▼ Many temperate forests in the Eastern US are young and have experienced decades of elevated inputs of acidic compounds from the atmosphere. As a result, I used the Fernow Experimental Forest Long Term Soil Productivity (LTSP) experiment near Parsons, WV to determine how ongoing acidic deposition may affect total ecosystem carbon (C) storage, stand level dynamics, and soil and foliar chemistry in a young regrowing temperate deciduous forest. I also assessed the potential for acidic deposition effects to cascade up into higher trophic levels through its effects on a soil invertebrate. The LTSP experiment is a randomized block design in which ammonium sulfate is experimentally added to the soil in order to accelerate the acidification of forest soils in a way that is similar to the effects of long-term nitrogen (N) deposition from the atmosphere.;I found that 13 years of ammonium sulfate additions to a regenerating deciduous forest stimulated its ability to store C. This response was driven primarily by increased C storage in aboveground biomass and to a lesser extent by increased C stored in the forest floor. Despite the dominance of a single tree species, the overall response was a complex mixture of species-specific changes in the growth of individuals that may have been tempered by changes in stand density. I also found that after 10 years of growth with continual N and S additions, soil and foliar chemistry in an aggrading temperate deciduous forest show signs of soil acidification and calcium (Ca) and magnesium (Mg) depletion – suggesting that the ability of these regenerating forests to store C may diminish if acidification were to continue. Additionally, I found that liming may mitigate some of the negative impacts of acidification for experimental or management purposes. Finally, I also found that Pseudopolydesmus serratus millipedes, leaf litter processing invertebrates that contain high levels of Ca, are negatively affected by 13 years of simulated acidic deposition in temperate deciduous forests. The negative effect of N addition on millipede populations, however, could not be tied to a depletion of Ca from the soil and plants but, if widespread, could affect the Ca supply to organisms, like some bird species, that have high Ca requirements during critical stages in their life.;Overall, this research suggests that young regrowing temperate deciduous forests may currently be sequestering more C due to inputs of N from acidic deposition. However, the positive response may involve species specific and stand-level changes and may be short-lived due to soil acidification effects, which should proceed, or co-occur with, reductions in growth rates. The effects of N deposition may also potentially reach higher trophic levels such as consumers of P. serratus, whose populations were negatively affected by N inputs.

▼ Broad scale geographic variation in species diversity correlates with environmental variables in most taxa, but a mechanistic understanding of this relationship has remained elusive. More than a half-century ago, F.W. Preston observed that the number of individuals per species in species assemblages is log-normally distributed (with two parameters: the total number of individuals, I, and the number of individuals of the rarest species, m). Here, we show that ϕ, a proxy for m, is correlated with environmental variables in several datasets of trees, birds, fish, and invertebrates. Moreover, variation in species richness is more strongly related to this measure of rarity than to environment. In all the datasets we examined, structural equation models are consistent with the hypothesis that environmental variables affect species richness principally by affecting rarity, which in turn affects richness. We propose that geographic variation in the ability of species to persist at low densities provides a possible unifying explanation for global gradients of species richness. Our findings may have important implications regarding Earth’s biodiversity, highlighting the rarest species as those most at-risk but also important indicators for the ongoing consequences of climate change.

▼ Biology
Species interactions are central to the study of community ecology, but these interactions can change with context. For instance, predator-prey interactions can vary with species introductions, spatial scale and temporal scale, and we are still learning how such factors can influence the strength of these interactions. Studying species interactions via multifaceted approaches and at different scales aids in the understanding of local and large scale processes, and can lead to predictions of how our ecosystems will persist in the face of continued anthropogenic alteration of the globe. The present series of studies sought to explore spatial and temporal variability in marine predator-prey interactions and invasion dynamics. The first objective was to assess biogeographic variability in predator invasions in the field. The second examined spatial variation in niche breadth via field collections, laboratory dissections, and database development, and the third involved a series of laboratory and field experiments as well as population modeling to examine temporal variability in native and non-native behavioral interactions. Specifically for the first objective, I examined the strength of marine invasive species-induced trophic cascades across latitude, hypothesizing that a non-native tertiary consumer could facilitate non-native basal prey establishment through the consumption of a native secondary consumer. I further predicted that the ecological importance of this cascade may be reduced in the subtropics relative to the temperate zone due to stronger predation pressure at lower latitudes. I found evidence of a trophic cascade in both regions, but it was only maintained under ambient predation pressure in the temperate zone. My results also suggest that strong predation pressure on the non-native intermediate predators in the subtropics may explain the weakened cascade under ambient conditions. For the second objective, I tested the hypothesis of increased specialization at lower latitudes using Brachyuran crabs as a model system and diet as my measure for niche breadth, while controlling for range size, body size and evolutionary relatedness. I compiled a dataset on 39 crab species' diets from existing studies and conducted my own diet analyses on species collected in a temperate, subtropical and tropical region, resulting in a global comparison. I found that latitudinal position was correlated with range size for temperate species, but not for tropical species, and found no correlation between the other focal variables and latitude. These results suggest that ecological mechanisms (i.e. competition strength) may be driving patterns of niche breadth in the temperate zone, while evolutionary mechanisms may be more important in predicting niche breadth patterns in tropical systems. For the third objective, I examined the influence of native and non-native prey naïveté on intermediate predator invasion success. I hypothesized that 1) naïveté is greatest in earlier stages of invasion across all trophic levels,…

▼ Many ecological patterns and processes are functions of metabolism (Brown 2004), meaning the acquisition, transformation, and allocation of energy, materials, and information within the bodies of individuals and among members of human and other animal societies. Individual metabolic rate should influence behavior by determining the energy available for action as well as the rate at which the body requires fuel. First, I test a key prediction of the metabolic theory of ecology (MTE), that biotic interaction rates are characteristic functions of temperature. Findings support this prediction and suggest that herbivory, predation, parasitism, parasitoidy, and competition increase exponentially with temperature and that this increase echoes that of individual metabolic rates. Second, I extend a metabolic framework to foraging patterns and space use of traditional human societies. Together with colleagues, I build on Hamilton (2007) to offer a model that formally incorporates hypothesized mechanisms affecting population sizes and densities and territory sizes: temperature, productivity, seasonality, and trophic level (degree of carnivory). We test this model on a dataset of 333 traditional foraging societies using multiple linear regression. Interactions between explanatory variables were important, and the influence of temperature, productivity, and seasonality often depended on trophic level. In addition, coastal productivity allowed marine foragers to disassociate themselves from terrestrial energetic constraints and maintain high population densities, small territory sizes, and thus high levels of cultural diversity. A metabolic perspective is useful for interpreting patterns in large scale human ecology and suggesting underlying mechanisms. Third, I argue for a macroecological approach to human ecology and suggest the value of a metabolic perspective using examples from human foraging ecology, life history, space use, population structure, disease ecology, cultural and linguistic diversity patterns, and industrial and urban systems. The ability of a metabolic framework to inform our understanding of behavior, from the interaction rates of small ectotherms to cultural diversity and urban activity patterns in Homo sapiens, suggests the power and promise of this approach.

▼ Modern and fossil ecological data exist at very different taxonomic, spatial, and temporal scales. For modern ecology, data are typically collected at the species-level, cover square meter quadrats to the entire globe, and span days to decades at most. For fossil assemblages, spatial scale might be comparable to that studied by modern ecologists, but fossil data are taxonomically and temporally much coarser (respectively, order-, family-, genus-level at best, and 104-108 years). Recent research has shown that ecological patterns and the processes affecting them change across scale. Therefore, using modern ecological theory and methods to study fossil data is an incommensurate exercise and potentially produces spurious results. Moreover, scale varies by orders of magnitude even among fossil assemblages, so comparing fossil sites without an appreciation of scale may also lead to ambiguous conclusions. I argue that a disregard of scale within paleoanthropology has contributed to its inability to synthesize seemingly disparate paleoecological results into a coherent, unified framework. As a result, paleoanthropology has remained relatively stagnant regarding its understanding of how paleoecological processes drove hominin evolution. With this in mind, I adopt scale as a central theme in my dissertation and attempt to understand how ecological pattern and process change across modern and fossil scales in East African large mammal communities, and if these scale differences can be analytically reconciled. The results from my three research chapters show ecological patterns (and the relevant processes driving them) fundamentally change across modern and fossil scales. Thus, modern and paleoecological theory and data are each incomplete: modern ecologists need to analyze fossil data if they want to study ecology at large time scales, and paleoecologists need to examine modern data and theory in order to understand smaller-scale processes; simple extrapolation and interpolation will not do. For paleoanthropologists, that means it is less than straightforward to infer smaller-scale ecological processes (e.g., paleoenvironmental reconstruction, interspecific interactions) from fossil assemblages, and caution should be exercised when attempting to do so. I by no means offer a panacea for this scale issue, but hopefully my research will make paleoanthropologists more cognizant of scale and encourage future research on this topic. Only then can we finally begin to understand what exactly were the important ecological drivers affecting hominin behavior and evolution.

▼ The goal of conservation biology is to understand and prevent the loss of biological diversity. Modern conservation science relies heavily on four major quantitative methods: reserve site selection algorithms, species distribution models, population viability analyses, and species-area relationships. These methods, however, have several longstanding and unresolved shortcomings, including extensive data requirements, long computation times, and important simplifying assumptions, that limit their ability to inform conservation decisions in many real landscapes. This dissertation develops new approaches in quantitative ecology that address these shortcomings through the use of simulation modeling, probability theory, machine learning, modern statistics, and economic input-output analysis.Chapter 2 examines the optimal design of reserve networks for preventing extinction of terrestrial mammal species, demonstrating that the match between a species' body size and the spatial scale of a landscape can be used to determine which species will benefit from a clustered reserve network design. Chapter 3 derives two new macroecological metrics, similar to the species-area relationship, that provide probabilistic estimates of single-species extinction risks and community-wide extinction rates in landscapes undergoing habitat loss. Chapter 4 uses data from acoustic surveys to examine the road ecology of California bats, finding that total bat activity, and the activity of four common species, is decreased in the vicinity of large highways. Chapter 5 presents a "wildlife footprint" analysis that combines global bird and mammal range maps, data on the human appropriation of net primary productivity, and economic input-output tables to link specific human consumption activities to decreases in wild bird and mammal populations.

▼ Macroevolution and macroecology are concerned with the patterns in evolutionary and ecological data, respectively, which arise when observing multiple species over time and/or space. Species extinction and species pool functional composition are the macroevolutionary and macroecological patterns at the heart of this dissertation. The hypotheses and analyses in the three studies forming this dissertaiton were all framed in terms of how species functional traits can shape these emergent patterns. In my first study, I analyzed the Cenozoic fossil record of North American mammals to test two long standing hypotheses: the survival of the unspecialized hypothesis, and the Law of Constant Extinction. My analysis centers around a model of species duration as a function of multiple species traits, species’ phylogenetic relatedness, and species’ origination cohort. My results support the conclusion that generalist species will, on average, have a greater duration than more specialized species. I also find that species extinction risk increases with species duration, a result that is counter the Law of Constant Extinction. Additionally, I find that only some of the factors associated with extinction risk for Modern mammals could be considered risk factors for mammals from the rest of the Cenozoic, indicating a difference between the modern biodiversity crisis and “normal” extinction dynamics. My second study also deals with the survival of the unspecialized and the Law of Constant Extinction, but focuses on a different system: post-Cambrian Paleozoic brachiopods. An additional aspect of this study is an analysis of the relationship between extinction intensity and the strength of trait selection. I find support for greater survival among environmental generalists than specialists. I also find evidence that for geographic range and environmental preference, as extinction intensity increases, the selective importance of these traits increases. This result is evidence for a qualitative difference between background and mass extinction. The final study is an analysis of the changing functional composition of the North American mammal regional species pool over the last 65 million years. The goals of this analysis are to understand when functional groups are enriched or depleted, and how changes to environmental context may shape these changes. I find that mammal diversity is more strongly shaped by changes to origination probability rather than changes to extinction probability. I also find that all arboreal ecotypes declined throughout the Paleogene and disappeared from the species pool by the Neogene. Additionally, I found that most herbivore ecotypes expand their relative contribution to functional diversity over time. My desire with this dissertation is to present the types of analyses and results that are possible through a synthesis of macroevolution and macroecology. The first step to building any dialogue is to agree on a common language and I’ve emphasised an…

▼ Species richness of virtually all high-level taxonomic groups is strongly statistically related to climatic variables such as temperature and precipitation, and consistently so across space and time. These observations are consistent with a causal link between the number of species that occur in a given region and its climate. Although dozens of hypotheses have been proposed, the main mechanisms underlying this pattern remain largely unresolved. And, few ecological studies have attempted to identify regularities in the individual species distributions that make up the richness–climate relationship. Despite the complexities of species’ biologies, I found that, to a first approximation, species’ probability of occupancy at continental scales were generally well statistically explained by a Gaussian function of temperature and precipitation. This simple model appeared general among species, taxa and regions. However, although individual species’ ranges are strongly statistically related to climate, spatial variations in richness cannot be explained by systematic variations in species’ climatic niches. And, individual species track changes in climatic variables through time much more weakly than species richness tracks these changes, suggesting that richness is at least partly constrained by mechanisms independent of species identities. Moreover, at macro-scales, species richness was also not strongly predictable from the temperature at which clades have originated, from historical variability in climatic variables nor from local short-term extirpation rates. In sum, I rejected several prominent hypotheses aiming to explain richness–climate relationship and found several lines of evidence inconsistent with the common idea that climatic constraints on individual species, by themselves, can explain richness–climate relationship. I propose a mechanism to explain, as a first approximation, the continental biogeography of species distributions that relies on neutral processes of dispersal and local extinctions within species’ broad deterministic thermal tolerances.

▼ Billions of dollars have been invested in land protection as a strategy to conserve biodiversity based on the assumption that protected areas buffer species from processes that drive extinction. Increasingly, protected area expansion and connectivity are being incorporated into climate change adaptation strategies to facilitate anticipated shifts in species ranges in response to predicted changes in temperature and precipitation. However, the effectiveness of protected areas at maintaining biodiversity, either by reducing the risk of extinction or facilitating colonization into new areas, has not been well established. In addition, the growing reliance on multiple-use protected areas that allow resource extraction, such as timber harvest and mineral mining, has raised questions about whether multiple-use protected areas are equally beneficial for long-term biodiversity conservation as more strictly protected areas that limit active resource management. In order to address these questions using repeated Breeding Bird Atlas data, I first had to confront the limitations of existing approaches to account for imperfect detection by developing a novel modelling approach to addresses the gap between requirements of other multi-season occupancy models (i.e. repeated sampling) and existing datasets. I then applied that single-visit dynamic occupancy modelling approach to Atlas data in New York and Pennsylvania for 97 species to quantify drivers of colonization and extinction while accounting for imperfect detection in landscapes that varied by type and amount of land cover and area under protection. In general, protected areas increased colonization and lowered extinction probabilities to an increasing degree as both forest cover and neighborhood protection decreased, with particular benefits for forest breeding birds. Both strict and multiple-use protected areas increased colonization and reduced extinction more for mature forest species than early forest species, with the greatest benefits accruing when forest cover was relatively low. These results provided the most comprehensive evidence to date that protected areas can facilitate species persistence by both reducing the risk of extinction and providing attractive colonization sites as species’ ranges shift and that biodiversity conservation can be compatible with renewable resource extraction.

▼ Patterns of community structure and richness provide context for studies from microbial ecology, global
macroecology, languages, to Bayesian statistics. Diversity patterns for animals on land and their predictor variables are well studied. However, diversity patterns for bacterial communities and marine macroorganisms are not well studied or understood. Here I examine diversity patterns in caves, on the external surface of Chiroptera (bats), and in marine ecosystems. At the local to regional scale we investigate factors that drive bacterial community patterns in richness and composition in lava cave microbial mats and microbes on bats. Lastly, out of the cave and into the surface world, a global picture emerges of factors that drive community structure and richness from bacteria to apex predators in marine environments. I hypothesize that for cave microbial mats found in lava caves, local factors (i.e. sample site temperature and relative humidity) are important factors for determining community structure and richness. For bacteria on bats, a mix of local factors (bat species, bat body mass, location of capture) and regional factors (net primary productivity (NPP), annual mean rainfall) explain richness and structure of the microbial communities. In addition, the predictor variables for richness and community structure will vary with spatial scale (local to regional to landscape). In the global marine data set, richness and community structure will be dependent on net primary productivity, temperature, thermal lifestyle, and foraging behavior. At small scales, temperature and NPP will be variable in their predicting power, while at large scales they will be positivity correlated with species richness. Local factors likely drive the larger scale patterns in community structure and richness.

▼ This dissertation addresses the spatial dynamics of marine species in nearshore environments. These are some of the most productive and diverse regions on earth, providing essential goods and services to a large number of people around the globe. However, they are also under increasing stress from numerous perturbations such as oil spills, over-harvesting, and from changes in our atmospheric and oceanic climates. These disturbances are but a few examples for why it is important that we develop our understanding, and have some predictive capacity for the population dynamics of nearshore marine species. This is no trivial task for nearshore systems are complex, being characterized by interacting physical, ecological and social processes, and it is often difficult to understand why certain species are where, and how they might respond to certain management actions. Nevertheless, this has been the focus on my Ph. D., specifically, I have studied the role that ocean circulation plays in the demography of nearshore marine species. Most nearshore marine species are sedentary as adults, with home ranges ∼ 10 km. It is as newly spawned larvae that they travel greater distances, sometimes traveling hundreds of kilometers. During this stage, dispersal is primarily directed by ocean currents, and as a result, these species exist in a complex system of connected subpopulations. This spatial connectivity is the heart of my dissertation. I have worked on answering four research questions that each have a focus on connectivity: (1) what do patterns of larval connectivity look like in the Southern California Bight? (2) is connectivity important for the robustness of nearshore metapopulations and their management? (3) does connectivity change in time and, if so, what are the demographic consequences? (4) does connectivity in uence the composition of species in nearshore communities?

▼ AbstractEmotional Behavior in Couples with bvFTD: Implications for Caregiver Relationship Satisfaction and Psychological Well-beingbyAnna SapozhnikovaDoctor of Philosophy in PsychologyUniversity of California, BerkeleyProfessor Robert W. Levenson, ChairEmotions are an important part of marital life. Prior research indicates that patients with behavioral variant frontotemporal dementia (bvFTD) experience significant impairments in socioemotional functioning, including emotional blunting, inappropriate behavior and decreased empathy (Neary et al., 1998). These changes in patients often strain marriages and can lead to a decline in marital satisfaction and increase the risk of depression in the healthy spouse (Ascher et al., 2010, Braun et al., 2010). However, few studies have explored the emotional dynamics of couples living with bvFTD in a systematic way (Braun et al., 2009). The aim of this study was to extend our understanding of the emotional dynamics of couples where one spouse has bvFTD as well as to understand the association between emotional behavior during the marital interaction and the caregiving spouse’s relationship satisfaction and psychological well-being, looking specifically at depression. This study examined emotional behavior and emotional reciprocity of couples where one spouse is diagnosed with either bvFTD (N=30) or Alzheimer’s disease (N=30) in the context of a 10-minute naturalistic marital interaction in comparison to healthy controls (N=29). Emotional behavior was coded using the Specific Affect Coding System (SPAFF), which consists of five positive emotional behavior codes, ten negative emotional behavior codes, and a neutral code. Emotional reciprocity between spouses was established using the Allison and Liker (1982) statistic. The study also examined the relationship between positive and negative emotional behavior as well as escalating and de-escalating patterns of emotional reciprocity and the caregiving spouse’s self-reported marital satisfaction and levels of depression. The current findings reveal a loss of humor and reciprocity of positive emotion and an exacerbation in negative emotion (e.g., criticism, sadness) and conflict escalation in couples with bvFTD during a marital interaction. Furthermore, low positive emotion, high negative emotion and conflict escalation are associated with low marital satisfaction and high negative emotion is related to increased levels of depression in the spousal caregiver.

▼ Rhamphichthyoidea is a monophyletic clade of Neotropical electric fishes (Ostariophysi, Gymnotiformes), with about 55 known species, some still awaiting formal description. These species are widespread in tropical and subtropical freshwaters of South America, with a single species reaching Costa Rica in southern Central America. Rhamphichthyoid species inhabit a variety of lowland habitats including small sandy streams, floodplain oxbow lakes, and the benthos of deep river channels. Rhamphichthyoidea displays substantial morphological disparity, ranging in maximum total body size from 62 millimeters to about 1 meter, and exhibiting diversity of distinctive snout shapes. This phenotypic diversity is reflected in a broad range of ecological interactions and foraging modes. Here I studied the diversity of Rhamphichthyoidea at three levels: alpha diversity, species interrelationships, and macroevolutionary patterns. The first chapter presents results of a species level phylogeny using a total evidence approach, including a new classification based on phylogenetically diagnosed clades. The second and third chapters review the species diversity and boundaries of the poorly studied genera <i>Rhamphichthys</i> (7 spp.) and <i>Gymnorhamphichthys</i> (5 spp.). The fourth chapter presents an analysis of diversification through time, linking habitat occupancy with morphological aspects of snout shape in the radiation of Rhamphichthyoidea. In summary, this dissertation provides information on the species diversity, morphological characteristics, biogeography of the long-snouted rhamphichthyids; the phylogenetic relationships and a newly proposed classification of Rhamphichthyoidea; and adds to the understanding of general patterns of diversification within the Neotropical ichthyofauna.

▼ Energy is a common currency of ecological interactions. In this dissertation, I consider ecological energetics at different temporal, spatial and organizational scales. In my first chapter, I examine the energetics and thermoregulation of an enigmatic taxon: dinosaurs. From fossil evidence and assessment of living vertebrates I conclude that many non-avian dinosaurs were likely thermally intermediate, or 'mesothermic'. In my second chapter I detail the empirical evidence gathered to buttress my claim of dinosaur mesothermy. In my third chapter, I show how ecosystem rates of carbon flux, gross primary production and total biomass can be linked to individual body size. In my fourth and final chapter I explore how differences in metabolism and thermoregulation lead to predictable difference in marine predator biogeography, diversity and food consumption at ecosystem scales. A focus on organismal energetics offers insight into ecological interactions across space and time.

▼ The distributions of species are determined by intrinsic factors such as physiological tolerances as well as extrinsic factors of the environment such as the availability of resources. While physiological tolerances generally change over evolutionary time scales, changes in environmental productivity due to processes such as succession or seasonal progression often occur over ecological times. I address both physiology and resource availability as drivers of the distributions and diversity of endothermic birds and mammals using a macroecological approach and a metabolic perspective. Migratory birds, altering communities over seasonal cycles, provide a unique opportunity to investigate the drivers of distributions and diversity that act over ecological time scales. In my first chapter, I show that energy use by migrants in North American breeding bird communities tracks the seasonal dynamics of resource availability. Migrants dominate consumption in tundra and boreal forests where the summer pulse of resources is large relative to winter productivity. While migrants are more prominent during the breeding season, many species overwinter throughout the temperate zone where their role in communities is understudied. In my second chapter, I quantify the contribution of migrants to diversity and energy use in North American winter bird communities. Overwintering migrants contribute little to diversity but dominate energy use in many temperate communities. My third chapter represents the efforts of myself and colleagues to understand the physiological adaptations that determine the thermal environments in which species can persist. By expanding on the Scholander-Irving model of heat transfer, we show that mass independent changes to basal metabolic rate and thermal conductance allow endotherms to inhabit nearly the full breadth of thermal environments on Earth.

▼ Animals are an integral part of ecosystems: they consume and process materials, thus connecting the cycling of nutrients and matter through ecosystems. Freshwater mussels (order Unionoida) are a diverse group of bivalve mollusks that are highly imperiled. They reside on the bottom of rivers in discrete patches known as mussel beds and are aquatic ecosystem engineers that can have a strong impact on ecosystem function. Filter feeding mussels remove seston from the water and release nutrients (nitrogen and phosphorus) back to the riverbed and water through their egesta and excreta. These recycled nutrients fertilize and increase the abundance of algae, which are then eaten by stream animals such as insect larvae. Mussels also store nutrients in their soft body parts and shell, which are released when they die and can lead to algae blooms. Finally, mussel shells change near-bed hydrodynamics and provide habitat for other organisms. While all mussels perform these functions, different species exhibit considerable variation in their behavior, life history, and physiology, all of which describes their ‘functional niche’ or ecological role. This variation makes mussels ideal study organisms for investigating how species characteristics change through space and how this impacts ecosystem function. My dissertation contains three chapters: (1) variation in potential maximum size characteristics in freshwater mussels along a latitudinal gradient, (2) the impact of mussel ecosystem engineering on macroinvertebrates, and (3) how the effects of drought-driven mass mortality of mussels impacts ecosystem function. Collectively, my dissertation chapters examine how species’ characteristics allow them to cope with their changing environment.
My first chapter addresses mussel’s adherence to a general ecogeographic pattern, neo-Bergmann’s rule, that states larger animals are found in areas of lower temperatures (or higher latitudes). To examine this, I radially dissected shells from two mussel taxa that inhabit different thermal niches (Amblema plicata and Lampsilis spp.) to access annually deposited rings. From those annuli, I calculated von Bertalanffy growth parameters to describe the asymptotic maximum size of the mussels. As latitude is correlated with temperature, precipitation, and productivity gradients, I compared how different climatic gradients predicted this potential maximum length. I found that mussels grow larger at higher latitudes. Watershed precipitation and annual water temperature were negatively related to potential maximum size in both taxa. There is some evidence that thermal niche alters the size-latitude relationship. As climate change alters precipitation patterns and water temperatures, mussel taxa are likely to reach a smaller maximum size, which has implications for individual fecundity and thus population viability in the future.
For my second chapter, I used an integrative approach combining field experiments and a large field survey to investigate how the mechanisms and magnitude of ecosystem…

▼ Macroecology is an evolving ecological discipline that analyzes regional through global processes whose temporal interactions are especially significant over decades to millennia. Understanding if and how variables acting on rivers at large spatiotemporal scales affect fish communities is key to better river management and ecological theory. Using the American Fisheries Society’s standard sampling protocol, we sampled fish communities in contrasting (constricted and wide valley) hydrogeomorphic patches in both upland and lowland areas within terminal basin rivers in the Great Basin USA. We used species and trait-based community composition data, reach scale habitat data, and valley scale hydrogeomorphic data to analyze relationships between community composition and environmental variables. These relationships were evaluated using Mantel and partial Mantel tests to elucidate a causal network between the previously listed elements. Canonical correspondence analysis (CCA) was then used to illuminate specific variables within each environmental scale that may shape the composition of fish communities. Results indicated that valley scale hydrogeomorphic variables had a significant direct effect on fish community composition and explained more variation within the CCA than reach scale habitat variables. Correlations were stronger when based on a trait description of fish community composition with valley scale variables and more variance was explained in CCAs by environmental variables when a trait-based description was used.

▼ Energy is a core ecological currency and modeling its fluxes has provided important insights for fundamental questions of both species - environment interactions and ecosystem processes. The energetic need of species has received attention as being a core ecological trait that may reconcile the two perspectives. However, researchers have previously relied on crude measures of energy needs, depending on proxies in lieu of direct measurement. In addition, an integrative energetic framework accounting for species energy needs, energy flow through ecosystems, and energetic interactions between species is lacking. I present such a framework here and consider the energetic position or "metabolic niche" of a species in an assemblage. Primary productivity required (PPR) measures the amount of energy from primary productivity required to sustain the daily energy needs of a species. PPR quantifies the "metabolic niche" of species by accounting not only for basic energetic requirements, but also energy flow (and importantly, energy loss) in animal communities. Thus, PPR extends the species-based approach to consider potential constraints of community assembly at the ecosystem level.In Chapter 1 I present justification for the use of PPR as a valuable measure of energy needs in ecological studies at both the species and community levels. I quantify PPR for all mammals and birds globally and provide a first exploration of the major patterns. Further, I discuss implications of PPR across the fields of ecology, evolution, and conservation biology.In Chapter 2 I develop a model using PPRs of species to predict community-level abundance distributions. I show that PPR, by quantifying a single dividable resource axis, places species energy needs in a community context and provides accurate prediction of species abundance distributions.In Chapter 3 I quantitatively describe the strong relationship between energy needs and population abundance. I explore additional biotic, abiotic, and biogeographic predictors of abundance, highlighting the fundamental importance of energy needs and, after controlling for PPR, the lessened value of some predictors previously thought significant. In Chapter 4 I explore geographic patterns of community PPR distributions and describe how analyzing the shape of those distributions provides insight into how animal communities are assembled.

▼ Abstract: Ecological processes are responsible for shaping diversity patterns and its contribution degree vary according to the scale that they are measured. Investigate the effect of processes in different scales is the key to understand its dynamics and relative contribution in generating patterns. Fruit-feeding butterflies are widely used in many ecological studies and conservations activities as well. The diversity distribution of these organisms are frequently addressed at local scales, but patterns at wider scales and the relative contribution of processes are still poorly understood. Aiming to fill the knowledge gaps our objectives were: 1) compile data from fruit-feeding butterfly communities of Atlantic Forest, seeking to support analyses of broader diversity patterns. 2) Compare at a local scale, the effect of fragmentation and vertical structure of forests on the phylogenetic and species composition of fruit-feeding butterfly communities. 3) On a broader scale, evaluate the effect of landscape modification on the distribution of fruit-feeding butterfly species richness in Atlantic Forest. The compilation revealed that fruit-feeding butterfly inventories are mostly represented by unpublished historical data, which are concentrated near the butterfly research centers. Our results also demonstrated that processes related to habitat quality and quantity are important structuring factors of local and regional communities. At local scales the fragmentation and vertical structure of forests generated similar patterns of species composition and flight functional traits distribution. This suggests that habitat structure may act under a similar filtering mechanism in different spatial dimensions. On a regional scale, the fruit-feeding butterfly species richness seems closely related to forest remnants of Atlantic Forest, demonstrating that forest fragments are efficient in maintaining high richness. The richness hotspots location match with endemism centers of other taxa. Moreover, they are located near to sites which landscapes models predicted low richness, which demonstrate that an increasing landscape modification may lead to significant species loss. Although the importance of ecological processes vary according to observed scale, we confirmed that habitat loss is a determinant factor structuring fruit-feeding butterfly communities at different scales. In times that were established goals for stopping the biodiversity loss, we highlight the importance of diversity knowledge divulgation and management, as well as the prominent role of the impacts caused by natural landscape modification

▼ Behavioral interference between species can influence a wide range of ecological and evolutionary processes. For example, aggressive and reproductive interference can lead to competitive exclusion, facilitate invasions, and limit how species ranges shift in response to climate change. While empirical examples of these diverse outcomes abound, a general understanding of when these behaviors arise is necessary to improve predictions of species coexistence and patterns of biodiversity. One type of behavioral interference, interspecific territoriality, has been found to generate important ecological and evolutionary patterns across numerous taxonomic groups, yet still unknown are the ecological circumstances associated with interspecific territoriality and its likelihood to persist through time. Here I present the first comparative study of interspecific territoriality among all sister species of North American songbirds. I tested core hypotheses regarding the origins and maintenance of interspecific territoriality and evaluated the role of interspecific territoriality and hybridization in shaping species distributions and in determining the likelihood of closely related species transitioning from parapatry to sympatry. To do so, I conducted extensive literature searches to identify sister species pairs that exhibit interspecific territoriality and assessed whether ecological traits and morphological divergence predict interspecific territoriality. Among closely related North American songbirds, interspecific territoriality is pervasive, and interspecifically territorial species pairs have more recently diverged than non-interspecifically territorial pairs. Analysis of the ecological correlates of interspecific territoriality indicates that misdirected intraspecific aggression and resource competition can each lead to interspecific territoriality. These patterns have implications for the ability of species pairs to coexist in sympatry: time since divergence between closely related songbird species does not predict breeding range overlap, nor does interspecific territoriality enable closely related species to transition from parapatric to sympatric distributions. Instead, the combination of interspecific territoriality and hybridization appears to be an unstable state associated with parapatry, whereas species that are interspecifically territorial and do not hybridize are able to achieve fine-scale and coarse-scale breeding range overlap. In sum, these results suggest that interspecific territoriality has multiple ecological origins and that interspecific territoriality and hybridization together can have striking impacts on species ranges. Our work highlights the value of comparative analyses for identifying ecological causes and evolutionary outcomes of this important interspecific behavioral interaction.

▼ Aim
It is commonly asserted that climate presents the primary constraint on species’ geographic distributions, and therefore, that species' ranges shift in response to changing climate given their specific climatic tolerances. However, supporting evidence is surprisingly inconsistent. Alternatively, spatially structured processes (e.g., dispersal) could more strongly determine species’ geographic distributions. Is climate the primary determinant of species’ geographic distributions, or might non-climatic, spatial processes constitute a stronger influence, such that the effect of climate is indirect? This study tests a number of predictions made by each of these hypotheses, during a single period of time.
Location
Contiguous United States and southern Canada.
Methods
We used 19 species of passerine birds whose distributions fall entirely within the area sampled by the North American Breeding Bird Survey from 1990-2000. We related these distributions to the mean breeding season climate, geographic locations and neighbourhood effects. Two spatial scales were addressed to assess the geographic location of species’ ranges and species' distributions within ranges.
Results
On average, geographic coordinates and a model representing neighbourhood occupancy outperform a simple climatic model. After controlling for geographic coordinates, species occupancy is poorly related to climate. A neighbourhood model on average accounts for the majority of variance captured by geographic coordinates within ranges, and more for the continental placement of ranges. Spatially explicit variables are more important than macroclimatic variables in a predictive model of species occupancy on average.
Main Conclusions
The geographic distributions of wide-spread North American passerine birds appear not to be primarily determined by climate. Our results are consistent with the hypothesis that localized spatial processes such as dispersal are stronger determinants of both continental range placement and within-range distributions of North American birds.

▼ How have we arrived at the diverse set of complex species that we currently find in our world? Using statistical simulations of evolutionary processes, this study investigates how the fundamental minimum sizes of species increase irreversibly over time, and how complexities evolved along the way compound throughout that process. Our results imply that unless a random mutation opens up a new dimension of nichespace for the clade to expand within, the mutation will eventually become extinct due to inherent genetic drift.

▼ Coral reefs are threatened worldwide due to local stressors such as overfishing, pollution, and diseases outbreaks, as well as global impacts such as ocean warming. The persistence of this ecosystem will depend, in part, on addressing local impacts since humanity is failing to control climate change. However, we need a better understanding of how protection from local stressors decreases the susceptibility of reef corals to the effects of climate change across large-spatial scales. My dissertation research evaluates the effects of overfishing on coral reefs under local and global impacts to determine changes in ecological processes across geographical scales. First, as large predatory reef fishes have drastically declined due to fishing, I reconstructed natural baselines of predatory reef fish biomass in the absence of human activities accounting for environmental variability across Caribbean reefs. I found that baselines were variable and site specific; but that contemporary predatory fish biomass was 80-95% lower than the potential carrying capacity of most reef areas, even within marine reserves. Second, I examined the effect of current native predatory reef fishes on controlling the invasion of Pacific lionfish across the Caribbean. Native predators and lionfish abundance were not related, even when predatory capacity was relatively high within certain marine reserves. Third, as herbivorous fishes may facilitate coral recovery after warming events by controlling competitive macroalgae, I evaluated whether major benthic groups, such as hard corals, crustose coralline algae, and macroalgae, were associated with these fish assemblages across Caribbean and Pacific reefs. Although, macroalgae abundance was negatively related to herbivorous fishes across geographical regions, contemporary coral cover showed no association with herbivores abundance after a recent history of thermal stress. Finally, I analyzed the relationship between ~30 years of thermal stress anomalies and coral assemblages in the Caribbean and suggest that recent warming has partially promoted a shift in coral-community composition across the region that compromise reef functionality. My dissertation research highlights the complex interactions among functional groups in coral reefs, local stressors, and environmental variability across geographical scales, and provides novel insights to reevaluate conservation strategies for this ecosystem in a rapidly changing world.

▼ This thesis uses a range of different size spectra to compare contrasting benthic habitats in the aquatic realm. Temporal and spatial variation in benthic size spectra were investigated across a full salinity gradient (i.e. from freshwater, through estuarine to marine) in the River Yealm, south Devon, in order to gauge the influence of large differences in taxonomy and evolutionary history. Abundance and biomass size spectra showed a similar pattern among sites in all seasons but winter, suggesting that the size structure of benthic communities may be similar in sites with very different community compositions. A subsequent study comparing size spectra across salinity by employing artificial substrata suggested that substratum type also had little effect on the size structure of these benthic communities. A technique was developed for obtaining microbial size distributions for benthic communities and showed that microbial size structures were also similar between the marine and freshwater sites within the Yealm system. A final study demonstrated that the shape of size spectra was clearly affected by metal contamination. Size spectra across a salinity gradient -(i.e. from freshwater to lower estuary) in the highly contaminated Fal system were very different to those in the uncontaminated Yealm, due mostly to the low macrofaunal abundance in the former. This thesis is the first to assess patterns in benthic size spectra across a full salinity range in the same system. It is hoped that it will provide a base line for further studies in this exciting research area in macroecology and that biomass spectra might also prove useful as metrics for biomonitoring.

▼ Rapidly growing research on mothers’ perinatal
depression, has demonstrated significant links among mothers’
depressive symptoms during pregnancy and the first year postpartum,
their parenting, and multiple aspects of children’s development.
This prospective longitudinal study contributes to research on
mothers’ perinatal depression by examining the mechanisms by which
maternal perinatal depression is associated with children’s
adjustment early in development in a sample of 204 Mexican-origin
adolescent mothers (Mage at Wave 1 = 16.80, SD = 1.0) and their
children (58% boys). I expected that adolescent mothers’ negative
parenting behaviors would mediate the associations between mothers’
perinatal depressive symptoms and three child outcomes:
internalizing symptoms, externalizing behaviors, and cognitive
ability. I further hypothesized that mothers’ perceived social
support from their family would modify the extent to which mothers’
perinatal depressive symptoms negatively impact their parenting
behaviors and their children’s developmental outcomes. Mothers
reported on their own depressive symptoms, their perceived social
support from their family and their children’s internalizing and
externalizing problems; negative parenting was assessed using
observational methods; and children’s cognitive ability was
assessed using standardized developmental assessments. In this
sample, adolescent mothers’ negative parenting behaviors did not
significantly mediate the relations between mothers’ perinatal
depression and children’s developmental outcomes. Further,
perceived social support did not significantly buffer the effects
of mothers’ perinatal depression on mothers’ negative parenting or
children’s developmental outcomes. However, in line with
hypotheses, results indicated that mothers’ prenatal depression had
a wider impact on children’s adjustment outcomes than mothers’
postpartum depression, which appeared more specific to children’s
internalizing problems. Discussion focuses on implications for
intervention addressing adolescent mothers’ perinatal depression,
as well as the need to continue to explore protective factors that
have the potential to disrupt the negative intergenerational
transmission of risks.

▼ Temperature is a major abiotic factor governing organismal performance and biotic distribution patterns worldwide. How different spatial resolutions of temperature variation relate to the thermal adaptiveness of organisms living within these environments informs predictions of physiological range limitations and response to climate change. Here I use Neotropical army ants as a model system to test broadly developed macrophysiological predictions on the scale of tropical microclimates and elevation clines. Social insect colonies make particularly interesting models for this purpose, as they enable the testing of predictions on both the level of the individual and the social group (colony). Here I form a new set of predictions for how insect societies are constrained and benefited by their thermal environments. I demonstrate novel patterns in tropical thermal tolerance due to soil microhabitat, elevation, and seasonality and discuss how these patterns interplay with the adaptiveness of castes in ant colonies. I also report novel differences in social thermoregulation across an elevational thermal cline and across brood ages in an above-ground nesting army ant species with a detailed study of thermal tolerance and thermoregulation in a below-ground army nest. The findings of this work suggest benefits in the incorporation of detailed microclimate use and social parameters in models predicting the ecological effects of climate change. These projects also form new testable hypotheses for future work relating to the thermal ecology of social insects.

▼ Despite being the most studied species on the planet, ecologists typically do not study humans the same way we study other organisms. My Ph.D. thesis contributes to scientific development in two ways: i) synthesizing our understand of the inter and intraspecific variation in social behavior in an understudied rodent lineage, the caviomorphs, providing a comparative context to understand social evolution in general, and 2) developing a macroecological approach to understand the metabolic trajectory of the human species. Through comparative analysis, chapter 2 synthesizes the available information on the diversity of sociality in the caviomorph rodents, both within and across species. Studies and theory derived from better-studied mammalian taxa establish an integrative and comparative framework from which to examine social systems in caviomorphs. We synthesize the literature to evaluate variation in space use, group size, mating systems, and parental care strategies in caviomorphs in the context of current hypotheses. We highlight unique aspects of caviomorph biology and offer potentially fruitful lines for future research both at the inter and intraspecific levels. We can gain unique insights into the ecological drivers and evolutionary significance of diverse animal societies by studying this diverse taxon. Chapter 3 outlines core ecological principles that should be integral to a science of sustainability: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per-capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development. Chapter 4 applies a socio-metabolic perspective of the urban transition coupled with empirical examination of cross-country data spanning decades. It highlights the central role of extra-metabolic energy in global urbanization and the coinciding transition from resource extraction to industrial and service economies. The global urban transition from resource producers in rural areas, to industrial and service employment in urban systems is fuelled by supplementing extra-metabolic energy in the form of fossil fuels for decreasing human and animal labor. Collectively, I hope this work demonstrates the utility of comparative analysis and synthesis in understanding the evolutionary ecology of sociality and the power of a macroecological approach in understanding the metabolic ecology and trajectory of the human species.

▼ Body size is a trait under selection. Genetic drift, climate, diet quality, and biotic interactions all select upon body size at the population, species, and community levels. These factors can be important in the context of rapidly changing climate. One of the ways an animal can persist in its environment is through morphological adaptation
in situ. Here, I investigate four questions relating to the evolution of body size: (1) what is the limit in body size change in response to climatic change; (2) how does body size influence the thermal tolerances of animals; (3) how does body size evolve over space and time; and (4) what are body size relationships between predators and their prey. I employ both the fossil and modern record, take both a macro- and micro- approach, and investigate both the terrestrial and marine realms. Overall, my dissertation demonstrates that species overwhelming evolve body size as a mechanism to persist in their environments.

▼ Boreal and arctic regions are predicted to warm faster and more severely than temperate latitudes. They contain large stocks of below- ground soil carbon in peatlands and frozen soil, and the flux of the soil C to the atmosphere may be a strong feedback to climate change. Increases in air temperature due to climate change will increase surface soil temperatures, soil temperatures at depth, active layer depths, and growing season length, but not degrade permafrost by 2100 at this site. Both wildfire and climate change increase active layer depths by 25 cm, but effects of wildfire diminish following vegetation recovery.
