▼ Predators may play an important role in affecting the fitness of preys. Many organisms have thus evolved strategies to prevent predation. Recognition of predator presence may be achieved by vision, olfaction, tactile sense or detection of water motion. Some organisms sense predators directly; others associate the injuries of victims to the presence of predators. There are many brittlestars (Ophiocoma scolopendrina) at the intertidal zone of Kenting, southern Taiwan and they suffer high frequencies of injuries in the wilds. Since their predators are likely to be diverse, we want to know if O. scolopendrina has the ability to sense the presence of predators, indirectly. We have two hypotheses: firstly, the avoidance behavior is elicited specifically in response to predators, secondly, the avoidance behavior is a general response to unfamiliar elements in the water mass. Our experiments revealed that the tested individuals would avoid conspecific viscera liquids and also that of other echinodermsâ. They are more likely to respond to conspecific viscera liquids. And O. scolopendrina hardly respond to solutions prepared from other organisms, e.g., fish, pork, macroalgae, freshwater. This behavior may help brittlestars reduce the probability of encountering predators. The results are compatible with the first hypothesis only. The effect of tide was also explored by testing in different times, but the frequencies of avoidance responses were independent of the tide. Furthermore, the subtidal species Ophiocoma dentata was also tested for the behavior. They escaped from conspecific viscera liquid as well as that of O. scolopendrina. This species, however, could not distinguish the liquids from the two brittlestar species. In conclusion, the avoidance behaviors of the ophiocomid brittlestars are adaptations for avoiding predators, not for avoiding unfamiliar environments.

▼ The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency. The environment acts directly on communities by causing direct mortality and changes to vital rates of individuals. However, the environment can also exert indirect effects on communities by changing the nature of biotic interactions. This occurs either through changes to the physiological performance of interacting species or through shifts in the abundance of other species in the community. Much of the effort to understand how global change will influence communities has focused on direct effects of environmental conditions. However, the essential influence of biotic interactions suggests that we will need to improve our conceptual understanding of indirect environmental effects to better predict outcomes of anthropogenic change. Understanding how the interactions of predators and prey are vulnerable to environmental context may provide a useful pathway to link relatively well-resolved individual effects of climate change to a broader community context. Predators are often important in determining community structure and stability through their control of lower trophic levels. However, predators also tend to be particularly sensitive to environmental stress. As a result, environmental stress models predict that the impacts of predators will lessen as stress increases, which could weaken existing processes regulating communities. Top predators, which often have the strongest impacts, may be especially vulnerable to climate change because of their large body size, energy needs, range requirements, and dependence on prey populations. The effects of environmental change on top predators have been justifiably well-studied, yet changing contexts require a more comprehensive view of which species may be important in novel environmental contexts. Subordinate predators are often weak interactors in communities, but they may play increasingly critical roles if top predators decline. Similarly, because weak interactions are highly variable, shifting environmental contexts could lead to different outcomes with subordinate predator interactions. Communities that experience high environmental variability across short spatial and temporal scales, such as rocky intertidal communities, are particularly useful for examining effects of environmental context on predator-prey interactions. The rocky shores along the US west coast have a rich history of study, enabling us to combine new insights and existing knowledge to build a greater context for predicting the impacts of environmental changes. Due to anthropogenic climate change, communities along rocky shores in the NE Pacific are predicted to experience warmer air temperatures, intensified upwelling, and greater exposure to low pH waters.

▼ Abiotic variables are well known community regulators and can strongly influence species distributions when they are outside of a species physiological tolerance limits. However, environmental variables within tolerance limits may also alter species distributions, morphology, predator-prey interactions, and influence the structure and function of communities. The purpose of this study was to determine how abiotic variables (notably turbidity) alter diversity, species distributions and abundances, predation rates on and species morphology. Texas Parks and Wildlife Department Fisheries Independent Survey Data from 1991-2008 were used in addition to field surveys of St. Charles Bay to determine the effects of turbidity on fish and crab diversity and abundance. Feeding assays were conducted in the field using groups of 5 mud crabs and 10 juvenile oysters to assess feeding rates in high and low turbidity. Juvenile oysters were also allowed to grow in the field to test the effects of turbidity on oyster growth. In addition, the effects of wave energy on oyster reef species composition and size were assessed using field surveys. I found that turbidity affects top-down control and biodiversity in estuaries and has similar effects to salinity and temperature. Elevated turbidity reduced fish diversity and abundance (p < 0.01), while increasing the diversity and abundance of crabs (p < 0.01). Predation by visual fish predators was also reduced in elevated turbidity (p = 0.02), which leads to an increase in the abundance of crabs and increased predation on mud crabs in high turbidities (p = 0.03). Juvenile oysters respond to increased crab abundance by growing heavier shells, which may lower fecundity. In laboratory assays, increased turbidity decreased the predation efficiency of visual predators (fish) but not of chemosensory predators (crabs). Differences were found between wave exposed and wave protected areas. Areas with higher wave energy had fewer species (p < 0.001) and the average size of species was smaller. This research identifies turbidity as an important variable within estuarine systems and extends the effects of wave energy from rocky intertidal systems to oyster reef communities. Both of these variables should be considered for effective management and restoration of estuarine communities. Advisors/Committee Members: Delbert L. Smee (advisor).

▼ Alien predators pose a pervasive threat to native species globally, yet our understanding of the behaviours that allow them to forage so effectively in novel environments is relatively limited. Many alien predators are mammals, relying upon olfaction to acquire information on prey location and hone their foraging effort. Understanding how predators occupy the landscape and use the spatial context of prey odour cues to decide where to devote foraging effort may explain the vulnerability of prey, and offers opportunities to alter odour environments in order to disrupt predator success. In this thesis I examine movement patterns of predators at increasing ecological and spatial scales to gain insight into factors that motivate foraging decisions and influence prey vulnerability. Using a combination of semi-wild and field-based experiments I investigated how spatial variation in olfactory cues (or ‘chemical camouflage’) influences the foraging behaviours of three alien predators. Firstly, using wild house mice, Mus musculus, I found that when prey are camouflaged, predators can show rapid temporal improvements in foraging success, although the degree of improvement depends upon prey quality. Secondly, using stoats, Mustela erminea, I found that increased search costs influenced a predator’s decision to switch to alternate prey, but that its foraging motivation was sensitive to the ease with which alternate prey were found. Thirdly, using free-living populations of black rats, Rattus rattus, I found that egg survival could be significantly enhanced by priming rats with birds nest odour cues. I was able to induce perceptual filters such that rats ignored formerly conspicuous prey odour cues even when eggs were present. Finally, using a multi-predator (red fox, Vulpes vulpes, and dingo, Canis lupus dingo) landscape, I show that unpredictability in predator behaviour is another layer of risk for prey to negotiate. My results indicate temporal variability of predator movements may serve to enhance prey vulnerability. In combination, my thesis demonstrates that the behaviour of alien predators influences the vulnerability of prey at multiple scales, from an individual within a patch to a species within a larger community. The olfactory conspicuousness of prey is a primary element motivating foraging decisions of alien predators, with prey vulnerability curtailed when the spatial variability within odour backgrounds is reduced.

▼ Predator-prey interactions have played a strong selective factor in the evolution of predator avoidance behaviour of prey. At an individual level predator recognition involves the understanding and inspection of a predator and discrimination between whether it poses a threat or not. Recognition is than followed by a defence response such as fight, flight or avoidance. However, in order for prey to appropriately and successfully respond and avoid predation, it is essential that prey species recognise a predatory threat in the first place. The isolation of prey species on predator free islands, geographically isolated continents (such as Australia) and predator free fenced reserves means that prey are increasingly isolated from predator driven natural selection processes. Australia has the highest contemporary mammal extinction rate in the world. Substantial evidence indicates that predation from introduced mammalian predators (feral cats and red foxes) are the main cause for these extinctions. Predator proof fences are now considered an important resource for ongoing conservation efforts, however, their long term effectiveness in terms of practical viability are still being evaluated. There are a number of theories that attempt to predict the responses of prey to their predators, particularly in environments where prey are isolated from predators and/or predators are introduced and may be considered ‘novel’ to the native fauna within that environment.In Chapter 1, I provide an overview of the current status and knowledge gaps in prey predator recognition, with particular focus on three native, threatened marsupials. Within Chapters 2, 3, 4 and 5 I carried out a number of olfactory and/or visual predator recognition experiments in order to explore: (1) predator recognition skills and abilities of threatened species within predator free fenced reserves, (2) whether seemingly ‘naïve’ prey species can develop predator recognition skills, and (3) the influence of evolutionary and ontogenetic experience on predator recognition. Results from these chapters provide support for the idea that one rule does not fit all when it comes to prey predator recognition. Rather prey predator recognition is species specific, highlighting the need for a paradigm shift if threatened species are to have a ‘future beyond the fence’.

▼ Vegetation structure plays a pivotal role in predator-prey interactions, because it influences the effectiveness with which predators are able to detect, pursue or ambush their prey, and determines the opportunities for prey to avoid being exposed to predators. Therefore, changes in vegetation structure may alter the impacts of predation on populations of prey species. In recent decades, populations of small mammals have collapsed across much of the savannah biome of northern Australia. The causes of this decline are not known, but predation by feral cats, intensification of fire regimes, and intensified grazing by introduced herbivores have all been implicated as possible causes by correlative and circumstantial evidence. However, we do not understand the mechanisms by which these factors, alone or in combination, affect population size in small mammals. Without this mechanistic understanding it is difficult to prescribe management interventions that will protect small mammals from further declines and allow recovery. I investigated interactions between predation by feral cats and vegetation structure in a study area in the central Kimberley region of northwestern Australia, to test whether one effect of fire and grazing regimes is to amplify the impacts on small mammals of predation by feral cats. I addressed three specific objectives. First, I measured population density of cats differed in areas with contrasting fire and grazing regimes. The second objective was to test how the movements of individual cats were influenced by vegetation and habitat structure, and especially to show whether cats preferentially hunted in burnt or grazed areas. The third objective was to derive direct measures of kill rates of feral cats, to show how these were influenced by habitat characteristics. To determine cat density, I deployed six arrays of infrared cameras across the study area during 2012 and 2013. The arrays were allocated evenly to areas with and without large introduced herbivores, and ranged across areas with differing fire histories. Each array consisted of 15 or more cameras deployed for one month. All cats ‘captured’ on camera were individually identified, and density was estimated using spatially-explicit mark-recapture analyses. Density at all six arrays was generally similar (mean 0.18 cats per km2, with SE of 0.08). There was no significant difference in density between grazed and un-grazed arrays, despite a five-fold difference in small mammal abundance. These results demonstrate that cats occur at low density in the Kimberley compared to other parts of Australia, and that population density does not increase when small-mammal abundance increases in ungrazed areas. To investigate movement behaviour and fine-scale habitat selection by cats, I deployed GPS collars on 32 cats in landscapes with contrasting fire and grazing treatments, and used discrete-choice modelling in relation to detailed habitat measures to reveal the movement decisions that underlie habitat selection by individual cats. Cats selected…

▼ When multiple predators foraging together have different individual consumption rates than predators foraging in isolation, they exhibit non-independent multiple predator effects on prey. I examined multiple predator effects in a system consisting of invasive green crabs (Carcinus maenas L.), native rock crabs (Cancer irroratus Say) and benthic macrofauna prey. First, I examined multiple predator effects when green crabs and rock crabs forage on soft-shell clams (Mya arenaria L.) in different habitat types (sand, sand with artificial seagrass) and assessed the behavioural mechanisms responsible for the observed predation effects. Independent multiple predator effects on prey were detected for most conspecific and heterospecific pairs in both habitat types. In general, crab foraging behaviours were not affected by the presence of another predator. Interactions between predators did not influence foraging behaviours because encounters were infrequent, short in duration and predominantly non-aggressive. A non-independent multiple predator effect on prey (marginally significant) was observed when green crabs foraged with rock crabs in artificial seagrass. This effect, however, could not be explained by the observed crab behaviours. Second, I investigated multiple predator effects when green crabs and rock crabs forage on a soft-sediment macrofauna community. Because crabs did not have significant predation effects on the community throughout the experiment, I did not evaluate multiple predator effects on prey. It is possible that crab predation was not important in regulating the macrofauna community, in which case multiple predator effects were non-existent. Predation may have been suppressed due to a combination of factors, including interactions between predators, harsh environmental conditions or a sub-optimal prey field. Alternatively, my ability to detect significant predation effects may have been hindered because of prey movement in and out of cages or low statistical power. Overall, results from this thesis demonstrate that multiple predator effects on prey may differ with habitat and highlights the importance of conducting behavioural observations to better understand interactions between predators and the resulting consequences for prey. Multiple predator effects on a soft-sediment community should be re-evaluated to assess the importance of these crab species in regulating benthic macrofauna under natural conditions.

▼ One of the central channels of nematode-environment interactions is through small molecules (non-polymeric chemical entities with a molecular mass <1000 Daltons). Nematodes release an abundance of small molecules which affect their environment, such as the ascarosides, di-deoxy sugar lipids which control the development and behavior of nematodes and other members of their environment. Through the advancement of high-resolution mass spectrometry and analysis software, we now find a wealth of other small molecules produced by nematodes which play key roles in their environmental interactions. Herein the author describes the integrated use of 2D NMR and high-resolution UHPLC-MS/MS to aid metabolomics of complex natural samples to characterize small molecules that regulate interactions between nematodes and their environment. Combining these analytical techniques with biological assay data, the author has characterized small molecules from nematodes which elicit defensive responses in other nematodes and affect microbial and nematode growth. The library of small molecules presented in this dissertation provide a new layer of structural diversity in nematodes and define a path forward in discovering other molecules of their kind. The novel small molecules shown in this thesis include - Branched chain sulfolipids (sufal/ac), molecules that cause defensive behavior in prey nematodes that appear to be linked to the development of the predator nematode’s mouth dimorphism. Cyclic sulfates (cysul), a class of metabolites unprecedented in nature, with possible epoxide precursors that suggest a straightforward biosynthetic pathway. The cyclic sulfates, unlike the branched chain sulfolipids, do not affect defensive behaviors in other nematodes, but may play a yet undiscovered role in a nematode’s interactions with its environment. Cyclopropyl lipids (cpfa), nematode derivatives of bacteriogenic metabolites which inhibit microbial growth in several species. The activity of these lipids was found to be stereochemically specific, suggesting that the effect on microbial growth may be through a signaling mechanism. Through these studies the author hopes to convey connections between small molecules created by nematodes with their environment and draw parallels with their potential effect on other organisms.

Considerando a importância do predador Podisus nigrispinus em programas de controle biológico de pragas e a escassez de estudos sobre as enzimas digestivas deste inseto, este trabalho teve como objetivo identificar, caracterizar e localizar as principais enzimas digestivas das glândulas salivares e do intestino médio de P. nigrispinus. Machos adultos de P. nigrispinus foram dissecados sendo as glândulas salivares e o intestino médio (dividido em anterior, médio e posterior) submetidas a testes enzimáticos para amilase, aminopeptidase, catepsina L, tripsina e α-glicosidase. Estas enzimas foram pré-purificadas e imunolocalizadas na região do intestino médio. O pH da glândula salivar foi 6,0 e do intestino médio foi de 5,6 na região anterior, 5,7 na mediana e 5,8 na posterior. A atividade específica das enzimas nas glândulas salivares e no intestino médio foi respectivamente: amilase 0,01, 21 mU/mg, aminopeptidase 0,19, 3 mU/mg, catepsina L 16, 3800 U/mg e α-glicosidase 0,27, 147 mU/mg de proteína. Tripsina não apresentou atividade no intestino médio, porém na glândula salivar sua atividade específica foi de 7 U/mg de proteína. Catepsina L foi a principal proteinase encontrada em P. nigrispinus e apresentou dois picos de atividade com pH ótimo 5,5 e massa molecular de 14 e 17 e Km de 32 e 11 μM.. Amilase, aminopeptidase, α-glicosidase apresentaram um pH ótimo de 5,1, 5,5, 5,8; Km de 0,1%, 0,03, 5 mM e massa molecular de 43, 125 e 90 respectivamente. Insetos alimentados há uma hora apresentaram diferenças na atividade enzimática de todas as enzimas analisadas e se manteve similar nos outros tempos. Os dados bioquímicos e da imunolocalização mostraram que a amilase, aminopeptidase e α-glicosidase de membrana foram as enzimas mais ativas na região anterior do intestino; já nas regiões mediana e posterior todas as enzimas estão ativas, porém com uma maior atividade de catepsina L e α-glicosidase solúvel. Estes dados mostram que a digestão inicial de carboidratos inicia na região anterior do intestino médio e termina na anterior e mediana. Já a digestão de proteínas tem o início na região mediana e termina na anterior do intestino médio, sugerindo que a membrana perimicrovilar nestes insetos tem um papel na compartimentação da digestão, na qual a anterior está relacionada à absorção de água e também na absorção de aminoácidos obtidos do xilema por esses insetos zoofitófagos.

Considering the importance of the predator Podisus nigrispinus in programs of biological control of pests and the poor studies on the digestive enzymes in Hemiptera, this study aimed to identify, locate and characterize the major digestive enzymes of the salivary glands and midgut of P. nigrispinus. Adult males of P. nigrispinus were dissected and the salivary glands and midgut (divided into anterior, middle and posterior) subjected to enzyme tests for amylase, aminopeptidase, cathepsin L, trypsin and α-glucosidase. These enzymes were pre-purified and immunolocalized in the midgut regions. The pH was 6.0 in salivary…

O predador Podisus nigrispinus (DALLAS, 1851) (Heteroptera: Pentatomidae) é um agente importante de controle biológico no agroecossistema de soja. Ele tem sido criado em laboratório, com diversos tipos de presas e plantas, o que melhora suas características biológicas e reprodutivas. O objetivo deste trabalho foi avaliar efeitos de compostos seqüestrados de plantas de soja pela presa natural Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae), comparada à presa alternativa Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae), nas características reprodutivas e no crescimento populacional de P. nigrispinus, com ou sem plantas de soja. Dois ensaios independentes foram realizados, o primeiro com planta e o segundo sem planta. No primeiro, P. nigrispinus foi criado em plantas de soja da cultivar UFV 16, com lagartas de A. gemmatalis criadas com dieta artificial (T1); lagartas de A. gemmatalis criadas com folhas de soja da cultivar UFV 16 (T2); e pupas de Tenebrio molitor (T3) ou pupas de A. gemmatalis criadas com folhas de soja (T4). No segundo ensaio P. nigrispinus foi criado sem planta, com lagartas de A. gemmatalis criadas com dieta artificial (T1); e lagartas de A. gemmatalis criadas com folhas de soja da cultivar UFV 16 (T2) ou pupas de T. molitor (T3). No primeiro ensaio P. nigrispinus apresentou maiores valores da duração da fase ninfal no T2; sobrevivência ninfal nos T1, T2 e T3; peso de ninfas de quinto estádio e de machos e fêmeas, números de ovos e ninfas por fêmea e de posturas no T3; menor número de ovos por postura no T2; e maior longevidade de fêmeas nos T2 e T3. A taxa líquida de reprodução (Ro) e a duração de uma geração (DG) foram menores no T1. O tempo para duplicar sua população (TD) e as razões finita (?) e infinitesimal (rm) de aumento populacional foram semelhantes. No segundo ensaio P. nigrispinus teve maior duração da fase ninfal no T1; e maior peso do quinto estádio e de machos e fêmeas, maior número de ovos e de ninfas por fêmea e o de posturas e ovos por postura e maior longevidade no T3. A taxa líquida de reprodução de P. nigrispinus (Ro) foi maior no T3; a duração de uma geração (DG) menor nos T1 e T2; o tempo necessário para o predador dobrar sua população em número de indivíduos (TD) foi menor nos T3 e T1, e os valores das razões finita (?) e infinitesimal (rm) de aumento populacional maiores nos T3 e T1. Nos dois ensaios, os parâmetros reprodutivos de P. nigrispinus foram melhores com pupas de T. molitor, provavelmente devido às melhores qualidades nutricionais dessa presa e ao efeito de plantas de soja no predador no segundo ensaio. Esse predador pode ser utilizado em programas de controle biológico de A. gemmatalis, por ter apresentado crescimento populacional com essa presa.

The predator Podisus nigrispinus (Dallas, 1851) (Heteroptera: Pentatomidae) is an important biological control agent in the soybean culture and it has been reared in the laboratory with plant besides prey what improves its biological and reproductive characteristics. This work aimed to evaluate…

▼ Mule deer (Odocoileus hemionus) are an iconic species of wildlife, and populations of mule deer across much of the western U.S. have experienced recent fluctuations in size. Factors that affect the survival and subsequent recruitment of juveniles may be the preeminent cause of population fluctuations for mule deer in many areas. Many factors, including habitat loss, extreme weather, intense predation, timing and synchrony of parturition, and competition with other species may be influencing these changes. We studied two potential factors that can influence the survival of neonate mule deer in southern Utah. To better understand how predation affects mule deer, we first implemented a study of the response of mule deer to removal of coyotes in southern Utah. We monitored survival and cause-specific mortality of neonate mule deer in areas where coyotes were removed and where they were not removed. We used multi-model inference within Program MARK and a known-fate model to estimate survival of neonate mule deer in both treatments (removal and non-removal), and to investigate factors potentially influencing survival. Our results indicated that coyote control can decrease mortality and increase survival of neonate mule deer in some situations. Removal of coyotes was most effective when removal efforts occurred for multiple consecutive years, and when control efforts occurred in or near fawning habitat. Second, we examined how synchrony of parturition affects the survival and cause-specific mortality of neonate mule deer. Reproductive synchrony is a strategy that influences the survival of juveniles and the growth of populations. Our objective was to test three possible explanations for the synchrony of parturition in mule deer; 1) pressure of predation on newborns, 2) a hybrid of predation and environmental effects, and 3) weather and food availability. To determine the effects of the timing of parturition on the survival and predator-related mortality of neonate mule deer, we used multi-model inference within Program MARK and a known-fate model. Our results indicated that the timing of parturition influenced survival and predator-related mortality of neonate mule deer. There was a lag between the onset of parturition of mule deer and predation of mule deer by fawns; individuals born close to the onset of parturition had higher survival and lower predator-related mortality than those whose births were delayed relative to the onset of parturition. Since predators selected for neonate mule deer that were born late, predator learning may partially explain reproductive synchrony in mule deer. Environmental factors may have a greater effect than predation on the survival of early-born individuals.

▼ Species have specific tolerances to a variety of environmental variables including temperature, dissolved oxygen (DO) and turbidity. Changes in either of these variables can therefore be expected to affect predator-prey interactions in shallow water ecosystems. Temperature drives the metabolic rates of poikilotherms, including fish. Hypoxic conditions generally affect larger fishes to a greater degree than smaller fishes, though the presence of physostomous swim bladders in certain species can alter that relationship. Finally there are species of fish that rely on vision for food acquisition while other species rely on other senses such as chemical cues. Changes in turbidity levels could therefore affect foraging efficiency of visual foragers. This thesis examines the role that each of these environmental variables (temperature, DO and turbidity) can have on community composition and therefore predator prey interactions, with a specific focus on the role of temperature in structuring predator-prey interactions. Laboratory, field and theoretical studies suggest that as temperature increases, encounter rates between predators and prey will increase. Prey are more active, spend more time foraging, and increase their use of risky habitats in warmer environments in laboratory experiments. In the field, prey and predator activity and/or abundance is positively related to temperature. These laboratory and field studies suggest that temperature increases should result in increased predation rtes of prey. Finally, the results of a dynamic state dependent optimization model also suggest that periods of warming will result in a lowering of the probability of survival of the fathead minnow, Pimephales promelas, a prey species, over the-ice free season. A reduction in DO levels in aquatic ecosystems results in a reduction in the number of and/or activity of predators present. This should result in a reduction in predation risk to prey. However, when endothermic predators are factored in to this equation, this reduction in risk may not occur. The presence of avian predators of small forage fish are directly related to the level of DO in the water, regardless of the abundance of prey fish present. This relationship is likely a result of behavioural decisions of prey that occurs in hypoxic conditions. In periods of low DO, prey fishes may exploit areas of higher DO that are closer to the surface of the waters. While their piscine predators may not be able to tolerate the low DO levels regardless of the position of prey in the water column, avian predators appear to be able to cue in to this increase in availability of potential prey, reducing any benefits that might occur by occupying surface areas where DO levels might be slightly higher than lower in the water column. As compared to temperature and DO, turbidity does not appear to affect the potential risk of predation to forage fish. The catch per unit effort (CPUE) of foragers who rely on vision and those that rely on chemical cues to forages, were not related to… Advisors/Committee Members: Abrahams, Mark (Biological Sciences) (supervisor), Anderson, Gary (Biological Sciences), Worley, Anne (Biological Sciences), Grant, James (Concordia University) (examiningcommittee).

▼ Exploring the causes and consequences of variation in species’ reproductive success is central to many research questions in ecology and evolutionary biology. For most species of birds, nest predation is the primary cause of nest failure and snakes have often been implicated as important nest predators. However, in other studies snakes are absent or infrequent predators. Here, I reviewed available nest camera studies from North America to better understand how the role of snakes as nest predators varies geographically and by snake species. I then conducted focal studies of two snake species (ratsnake [Elaphe obsoleta] and black racer [Coluber constrictor]) to better understand: 1) what factors influence nest predation rates by these two snakes, 2) which sensory mechanisms snakes use to locate prey, 3) how snake activity patterns vary with temperature, and finally, 4) how nest predation by snakes is predicted to change in a warming world. To address my first research question I reviewed 53 North American nest camera studies to identify geographic and species-specific patterns in nest predation by snakes. Snakes accounted for 26% (range: 0-90%) of recorded predation events and the ratsnake was the most frequent predator accounting for 65% of all recorded nest predation by snakes. Overall, snakes were more frequent predators at lower latitudes and in open macrohabitats. At a local scale, a single site in South Carolina, I found ratsnakes were the dominant snake predator of bird nests (28% of recorded nest predation) followed by corn snakes (E. guttata: 15%), black racers (12%), and coachwhips (Masticophis flagellum: 3%). In addition to monitoring 206 bird nests with video cameras to determine their fates, I simultaneously tracked 33 ratsnakes and 16 black racers using radiotelemetry. An examination of snake habitat use and avian nest survival revealed that racers and coachwhips were frequent predators of nests located near powerlines, due to their use of the shrubland habitat maintained below powerlines. Because racers and coachwhips were relatively infrequent predators of nests, however, daily nest survival rate was not influenced by distance to powerlines. Ratsnakes, the locally dominant nest predator, frequently preyed on nests near roads and distance to roads was the best predictor of daily nest survival of monitored nests. Radiotelemetry showed that ratsnakes were often near roads due to the associated forest edges, which ratsnakes are known to use for thermoregulatory purposes. Relatively little is known regarding how snakes locate nests. Because many snakes are active both during the day and night, I investigated how ratsnakes and racers locate prey, how temperature affects their daily activity patterns, and if the foraging mode of each species constrains when they are active. Because studies in Texas have reported a high rate of ratsnakes capturing adult birds on nests at night, I was particularly interested in understanding why ratsnakes switch to nocturnal activity, how they locate prey in… Advisors/Committee Members: Weatherhead, Patrick J.

▼ This dissertation explores the effects of varying the composition of aquatic and terrestrial habitats in a landscape: the aquatic to terrestrial ratio) on amphibians that use both the aquatic and terrestrial habitats during their lives. In Chapter 1, I first used meta-analysis and simulations to demonstrate that as the longevity of an amphibian increases, the elasticity of the population growth rate to perturbations in the aquatic: larval) habitat decreases. In Chapter 2, I examined the abundance of larvae of a long-lived amphibian, Ambystoma maculatum, across landscapes that varied in their aquatic to terrestrial ratios and found that larvae of this species were more dense in landscapes where aquatic habitat was scarce relative to terrestrial habitat. Because larval A. maculatum are top predators, they had more dramatic effects on the community composition of their prey in these isolated habitats, suggesting a result opposite to traditional metacommunity theory. In Chapter 3, I monitored the population level response of two common prey species, tadpoles of grey tree frogs: Hyla versicolor) and Blandchard's cricket frogs: Acris crepitans) to the presence and absence of predatory laval A. maculatum in large-scale experimental ponds. These prey species have very different longevities, and therefore differential use of the aquatic and terrestrial habitats. Population-level results suggest that, as expected, A. maculatum had a larger influence on the population dynamics of the shorter-lived A. crepitans than on H. versicolor. Finally, in Chapter 4, I found that the abundance of aquatic habitat in an area influences the ability of A. maculatum females to discern between oviposition sites of varying qualities. Studies of declining populations of amphibians typically focus on aquatic habitat and factors that affect larval survivorship and growth therein. However, this dissertation highlights the importance of both the aquatic and terrestrial habitats, and the ratio between the two, to overall population dynamics of amphibian species. These results will become more important as anthropogenic habitat destruction not only leads to an absolute loss of habitat, but also potentially alters the ratio of aquatic to terrestrial habitats on which amphibians depend.

▼ Artificial life evolutionary systems facilitate addressing lots of fundamental questions in evolutionary genetics. Behavioral adaptation requires long term evolution with continuous emergence of new traits, governed by natural selection. We model organism's genomes coding for their behavioral model and represented by fuzzy cognitive maps (FCM), in an individual-based evolutionary ecosystem simulation (EcoSim). The emergent of new traits (genes) in EcoSim is examined by studying their effect on individual's fitness and well being. We examine how the new traits are used to predict the value of fitness using machine learning techniques. A comparison between the genomic evolution of EcoSim and a neutral model (a randomized version of EcoSim) is examined focusing on their respective genomic diversity. In order to further emphasize the importance of genetic diversity to adaptation and thus the well being of individuals, we were encouraged to study the effect that genetic diversity has on fitness. EcoSim gives us the chance to study the relation between species genetic diversity and average species fitness without the limits in environmental conditions and time scales found in biological studies, but in highly variable environments and across evolutionary time. The ecological effects of predator removal and its consequence on prey behavior have been investigated widely. We investigated the effects of predation risk on prey energy allocation and fitness. Here the role of predator removal on the contemporary evolution of prey traits such as movement, reproduction and foraging was evaluated. Our study clearly shows that predation risk alone induces behavioural changes in prey which drastically affect population and community dynamics, A classification algorithm was used to demonstrate the difference between genomes belonging to prey co-evolving with predators and prey evolving in the absence of predation pressure. We argue that predator introductions to naive prey might be destabilizing if prey have evolved and adapted to the absence of predators. Our results suggest that both predator introduction and predator removal from an ecosystem have widespread effects on the survival and evolution of prey by altering their genomes and behaviour, even after relatively short time intervals.

▼ Due to the prevalence of threatening snakes in the evolutionary history and modern-day environments of human and nonhuman primates, sensory and perceptual abilities that allow for quick detection of and appropriate response to snakes are likely to have evolved. Many studies have demonstrated that primates recognize snakes faster than other stimuli and that snakes typically evoke a fearful response. However, few studies have varied specific perceptual features of snakes in order to examine primates??? responses to those features. One study suggested that nonhuman primates respond with anti-predator behavior to patterns on snake bodies, and pilot research in our colony of common marmosets indicated that some patterns are more threatening than others. In the current study, I tested the hypothesis that any pattern etched on a serpentine shape would generate a stronger anti-predator response than a serpentine shape without an etched pattern (H1). In addition, of the patterns etched on the serpentine models, I hypothesized that the marmosets would respond the strongest to a scaled pattern (H2). Lastly, I predicted that a pattern etched on a serpentine shape would generate stronger anti-predator behavior than the same pattern etched on a non-serpentine shaped object (H3). In order to test these hypotheses, various patterns (scales, stars, and lines) were etched on clay serpentine and triangle models and presented to individual marmosets. Models were presented in a blind and a researcher who was blind to condition scored the amount of time the marmoset looked into the blind prior to, during, and after stimulus presentation. Alarm vocalizations were recorded on a voice recorder and later scored by individuals who were blind to condition for latency to first call and number of alarm vocalizations emitted. Overall, the marmosets responded more strongly toward serpentine shapes with patterns than to serpentine shapes without patterns or patterns on non-serpentine shaped objects. However, the hypothesis that scales on a serpentine shape would generate a stronger anti-predator response than other patterns (lines and stars) on serpentine shapes was not supported. My study is the first to address particular snake characteristics that lead to anti-predator reactions in nonhuman primates, and the data serve as a foundation for future research to explore primates??? reactions to snakes.
