▼ The removal of marine species through fishing has impacted marine ecosystems for thousands of years. The pressure of exploitation on marine ecosystems has now reached a point at which there is serious concern over ecosystem well-being on a global scale. There has, therefore, been a global move towards an ecosystem approach to fisheries management. The objective of this study was to develop a decision tree framework to assess the status of exploited marine ecosystems, which could be successfully applied to numerous ecosystems and guide decision support under changing conditions. This work was based on that of the IndiSeas project, which makes use of indicators designed to detect the impacts of fishing on marine ecosystem around the world. A suite of indicators, selected from those utilised in the IndiSeas project, was divided into ecological and fishing pressure indicators. Ecosystem specific suites of environmental indicators were also included, allowing the framework to ascertain the impacts of environmental variability on ecosystem components. This is an important addition as currently many assessments of the impacts of fisheries do not account for the influence of the environment. The framework was developed for the Southern Benguela ecosystem and then applied, with minor adjustments to account for ecosystem-specific characteristics, to the South Catalan Sea and North Sea. Indicator time series were analysed making use of linear regressions, resulting in the assignment of a score between one and five, depending on the direction and significance of trends. Data series were divided into distinct periods based on known environmental changes or shifts within ecosystems. Careful consideration was given as to whether fishing and environmental indicator trends could explain the observed trends in ecological indicators. A method of score adjustment was then developed to account for the impacts of both fishing and environmental variability on ecological indicators. Correlations were conducted to detect potential redundancies of ecological indicators and weightings were applied to decrease the contribution of correlated indicators to overall ecosystem trends. However, as correlations differed between indicators and amongst ecosystems, it was necessary to adjust the applied weightings for individual ecosystems. Results for the Southern Benguela classified the ecosystem as neither improving nor deteriorating during Period 1 (1978-1993) and Period 2 (1994-2003). During Period 3 (2004-2010) the ecosystem was classified as possibly improving. The South Catalan Sea was classified as possibly deteriorating during Period 1 (1978-1990) and neither improving nor deteriorating during Period 2 (1991-2010). The North Sea ecosystem was classified as neither improving nor deteriorating during Period 1 (1983-1992). During the second (1993-2003) and third (2004-2010) periods the ecosystem was categorised as possibly improving. When assessing fisheries impacts at an ecosystem scale there are typically high levels of uncertainty. However,… Advisors/Committee Members: Shannon, Lynne J (advisor), Jarre, Astrid (advisor).

▼ Freshwater ecosystems and their associated landscape features found in developing cities and urban protected areas are essential components of urban social-ecological systems providing city residents with cultural, provisioning and regulating services, all of which hold value. Understanding these values requires overcoming conceptual and methodological challenges so that the multi-dimensional nature, relating to the varying values, benefits, and trade-offs are understood. Understanding values, benefits and trade-offs is essential for ensuring informed and effective management of these services and the landscapes that provide them. This requires the development of tools and methods to predict how changes in land-use and management practices might affect the provision of such services. This study contributes to both the methodological and empirical literature by developing integrated and multidisciplinary approaches to assessing the beneficiaries of freshwater ecosystem services in an urban context and recognising the ecological, social and economic values assigned to ecosystem services over multiple spatial and temporal scales. The aim of this thesis was to assess how beneficiaries, stakeholders and managers within a developing city context, recognise, value and manage the multiple diverse ecosystems services associated with freshwater ecosystems as provided by different landscape features originating in an urban protected area. This aim was achieved by establishing who the beneficiaries of freshwater ecosystem services are, uncovering the spatial and temporal relationships these beneficiaries have with landscape features, determining the nature of ecosystem service values, benefits, impacts and trade-offs as experienced by the different users, as well as analysing the management policies and practices associated with urban ES. Drawing on accumulated as well as existing data sets, newly developed methods and approaches were implemented in this study. This work was primarily undertaken in Table Mountain National Park and in Cape Town, South Africa. A comparative analysis of the perceptions of park managers toward ecosystem service governance and management was undertaken in Table Mountain National Park and in Tijuca National Park, in Rio de Janeiro, Brazil. Natural freshwater ecosystems (e.g. rivers), particularly when combined with built infrastructure (e.g. dams), provide highly valued features in landscapes, delivering multiple cultural services to city residents. Recreation, aesthetic and existence services were valued highest by respondents. People who live closer to the park use, and benefit from, the park's freshwater ecosystems more frequently than those living further away. Park visitors want ease of access in terms of distance to specific freshwater ecosystems, and then once there they want a diversity of activity options, such as recreation opportunities as well as places to reflect and meditate. The outcomes of the cultural-service study in this thesis have important management implications where insights… Advisors/Committee Members: Anderson, Pippin (advisor), O'Farrell, Patrick (advisor).

▼ Mangroves are specialised ecosystems developed along estuarine sea coasts and river mouths in tropical and subtropical regions of the world, mainly in the intertidal zone. Hence, the ecosystem and its biological components is under the influence of both marine and freshwater conditions and has developed a set of physiological adaptations to overcome problems of anoxia, salinity and frequent tidal inundations. This has led to the assemblage of a wide variety of plant and animal species of special adaptations suited to the ecosystem. The path of photosynthesis in mangroves is different from other glycophytes. There are modifications or alterations in other physiological processes such as carbohydrate metabolism or polyphenol synthesis. As they survive under extreme conditions of salinity, temperature, tides and anoxic soil conditions they may have chemical compounds, which protect them from these destructive elements. Mangroves are necessarily tolerant of high salt levels and have mechanisms to take up water despite strong osmotic potentials. Some also take up salts, but excrete them through specialised glands in the leaves. Others transfer salts into senescent leaves or store them in the bark or the wood. Still others simply become increasingly conservative in their water use as water salinity increases. A usual transportation or biosynthetic path as other plants cannot be expected in mangrove plants. In India, the states like West Bengal, Orissa, Andhra Pradesh, Tamil Nadu, Andaman and Nicobar Islands, Kerala, Goa, Maharashtra, and Gujarat occupy vast area of mangroves. Kerala has only 6 km2 total mangrove area with Rhizophora apiculata, Rhizophora mucronata, Bruguiera gymnorrhiza, Bruguiera cylindrica, Avicennia officinalis, Sonneratia caseolaris, Sonneratia apetala and Kandelia candal, as the important species present, most of which belong to the family Rhizophoraceae.Rhizophoraceae mangroves are ranked as “major elements of mangroves” as they give the real shape of this unique and interesting ecosystem and these mangrove species most productive and typical characteristic ecosystem of World renowned. It was found that the Rhizophoraceae mangrove extracts exhibit several bioactive properties. Various parts of these mangroves are used in ethnomedicinal practices. Even though extracts from these mangroves possess therapeutic activity against humans, animal and plant pathogens, the specific metabolites responsible for these bioactivities remains to be elucidated. Various parts of these mangroves are used in ethnomedicinal practices. There is a gap of information towards the chemistry of Rhizophoraceae mangroves from Kerala. Thorough phytochemical investigation can achieve the validity of ethnomedicines as well as apply the use of mangrove plants in the development of new drugs. Such studies can pave a firm base for their use in biomarker and chemotaxonomic studies as well as for the better management of the existing mangrove ecosystem. In this study, the various chemical parameters including minerals, biochemical…

Ph.D. University of Hawaii at Manoa 2013.

Coral reefs are some of the most diverse and productive marine ecosystems on earth. They are also among the most threatened by human disturbance. On a local scale, many of these systems are subject to over-fishing and land-based pollution, and on a global scale, these systems are impacted by climate change and ocean acidification: human activities clearly influence the structure of coral reef communities. However, before considering anthropogenic influence, it is necessary to consider the influence of local and regional environmental forcings on these ecosystems. In this research, I investigate natural environmental and anthropogenic drivers of benthic community organization in 41 coral reef ecosystems across the Pacific (14.2°S – 28.4°N, 144.8°E – 155.4°W). These systems have been the focus of a long-term, multi-disciplinary NOAA-led monitoring effort. I present a new methodological approach to spatially constrain environmental forcings at the scale of individual islands and atolls. The results indicate considerable spatial heterogeneity in environmental forcings, namely sea surface temperature, waves, chlorophyll-a concentration (a proxy for phytoplankton biomass) and irradiance. Further examination of long-term (10-year) chlorophyll-a concentrations revealed sustained increased phytoplankton biomass just offshore of reefs compared to surrounding oceanic waters around a majority (91%) of islands and atolls, providing widespread evidence of the occurrence and scale of the "island mass effect". Additionally, significant differences in horizontal gradients in chlorophyll-a between island and atoll systems were observed. Variations in reef area, bathymetric slope, geomorphic type (e.g. atoll versus island), and human population were identified as important drivers of increased phytoplankton biomass, together explaining 77% of the variability observed. In order to investigate biological-physical relationships at a smaller spatial scale, I focused on one oceanic atoll with a history of minimal human influence, Palmyra Atoll (5.8°N, 162.1°W). At intra-island scales, wave forcing and reef geomorphology were important drivers of benthic community organization. Model performance improved when hard coral cover was modeled in distinct morphological groups (encrusting, plating, branching), highlighting the response of coral reef communities to extrinsic physical forcings. Superimposed on natural variations in coral reef benthic community organization are the effects of anthropogenic disturbance.

▼ The circumpolar Arctic is experiencing dramatic environmental changes that are already impacting tundra ecosystems and northern communities that are intimately linked to the land. Increasing permafrost degradation, shrub encroachment, larger and more frequent fires, and increasing human development have significant effects on biotic and abiotic conditions in the lower Peel River watershed, NT. To understand and respond to rapid environmental changes, diverse knowledge perspectives are needed, so my M.Sc. research uses scientific and social scientific approaches to investigate environmental change in the lower Peel River watershed. I investigated the impacts of the Dempster highway on plants, soils and permafrost in the Peel Plateau by conducting field surveys at sites dominated either by tall alder (Alnus crispa) shrubs or by dwarf shrubs, at 30 m and 500 m from the highway. At each site I measured vegetation composition, alder growth, soil nutrients, litter and organic layer thickness, active layer thickness, and snow depth. We found that alder growth and recruitment were enhanced adjacent to the Dempster Highway, and dramatic alterations to plant community composition, soil properties and ground temperatures were observed where alder shrubs had formed closed canopies. Tall shrub sites adjacent to the road exhibited lower abundance of understory vegetation including mosses, greater litter and organic soil thickness, higher nutrient availability, and deeper snowpack. Biotic and abiotic changes associated with road effects feedback with alder canopy development, and have important implications for permafrost conditions adjacent to the roadbed, and potentially on road bed performance. This research contributes to our understanding of environmental changes caused by the highway and their consequences for infrastructure stability and pan-Arctic changes in vegetation cover. In a separate but complementary effort, I worked with Teetl’it Gwich’in land users and youth from Fort McPherson, NT to map observations of environmental conditions and changes. In the pilot year of a community-based environmental monitoring program, we employed participatory multimedia mapping with Teetl’it Gwich’in land users and youth from Fort McPherson, NT. I accompanied Gwich’in monitors on trips on the land to document environmental conditions and changes. Observations made by land users were documented using photos, videos and audio taken by youth, and land users provided detailed information about each observation in follow-up interviews. I compiled observations (photo/video, GPS location, and interview audio and transcript) into a web-based map where the public will be able to see changes on the land in the images and words of Gwich’in land users. The online map will provide a medium for local residents to communicate their knowledge and concerns about the environment, and will be useful for land management and planning, environmental monitoring, and adaptation.

▼ Agroforestry offers a land-use management methodology that may provide solutions to environmental degradation in the tropics. However, practitioners of agroforestry are faced with the dilemma of clearing more forest cover in order to increase crop size and sustain their income. The aim of this study is to understand the agroforester’s dilemma and to measure the value of the agroforestry ecosystem stewardship in yerba maté (Ilex paraguariensis A. St. Hil.) agroforestry parcels of the South American Atlantic forest eco-region. Biodiversity, carbon sequestration and vegetation cover were measured to be considerably higher in yerba maté (Ilex paraguariensis A. St. Hil.) agroforestry plantations than in neighboring monoculture crops. Agroforestry vegetation cover values were measured to have between 65-89% cover while monocultures had roughly 25% cover. Agroforestry stored carbon values ranged between 154.7-172.7 Mg C ha-1, compared to monoculture plantation values of 81.3 Mg C ha-1. Finally, as measured using the Shannon index, values of species richness ranged from 2.7-3.5 in agroforestry parcels and between 0.9-1.3 in monocultures, and values of evenness ranged between 0.6 and 0.8 in agroforestry parcels, and 0.2 in monocultures. These findings illustrate that yerba maté agroforestry can potentially contribute as a regional climate change mitigation strategy. Valuating and monetizing ecosystem services and engaging smaller farmers with worldwide ecosystem marketplaces offer the potential to expand the dialogue around payments for the valuable ecosystem services that agroforesters are providing. An analysis of market prices available within the ecosystem marketplace for total ecosystem services being conserved on agroforestry parcels amounted to a range in value between 16 – 160 ha-1 yr-1. To address environmental degradation in the Atlantic Forest region, in South America, governments should motivate environmental conservation to support a shift towards sustainable yerba maté production which supports livelihoods of small-scale farmers, economic justice and environmental sustainability.

▼ Interest in the role of organic nitrogen (N) to the N economy of forest ecosystems is gaining momentum as ecologists revise the traditional paradigm in N cycling to emphasize the importance of depolymerization of soil organic matter (SOM) in controlling the bioavailability of N in forest soils. Still, there has yet to be a coordinated effort aimed at developing general patterns for soil organic N cycling across ecosystems that vary in climate, SOM quality, plant taxa, or dominant mycorrhizal association: ectomycorrhizae (EM) vs. arbuscular mycorrhizae (AM). In this study, experimental additions of 13C15N-glycine and 15NH4+ were traced in situ through fine root and soil N pools for six North American forest ecosystems in an effort to define patterns of plant and microbial N utilization among divergent forest types. Recovery of 15N in extractable soil pools varied by N form, forest type, and sampling period. At all sites, immobilization by the soil microbial biomass represented the largest short-term (<24 h) biotic sink for NH4+ and amino acid-N, but differences in microbial turnover of the two N forms were linked to cross-ecosystem differences in SOM quality, particularly the availability of labile carbon (C). At the conclusion of the experiment, microbial N turnover had transferred the majority of immobilized 15N to non-extractable soil N pools. By comparison, fine root uptake of NH4+ and glycine-N was low (<10% total tracer recovery), but 15N enrichment of this pool was still increasing at the final sampling period. Since there was no significant loss of 15N tracer within the bulk soil after 14 days for any forest type except sugar maple, it suggests plants have the capacity to capitalize on multiple N turnover events and thus represent an important long-term sink for ecosystem N. Plants in all stands had some capacity to absorb glycine intact, but plant N preference again varied by forest type. Relative uptake of amino acid-N versus inorganic N was lowest in tulip poplar and highest in red pine and balsam poplar, while white oak, sugar maple, and white spruce stands were statistically near unity with respect to the two N forms. However, N uptake ratios were threefold higher in EM-dominated stands than in AM-dominated stands indicating mycorrhizal association in part mediated plant N preference. Thus, amino acids represent an important component of the N economies of a broad spectrum of forest ecosystems, but their relevance to plant nutrition likely varies as a function of microbial demand for C as well as N.

▼ Numerous "Fynbos" species of the Cape Floristic Region (CFR) have particularly fine, narrow leaves. The rates of transpiration and heat loss are partially dependent on boundary layer conductance, which is determined by leaf shape and size, surface modifications and wind speed. We expected fine-leaved species with higher boundary layer conductance to transpire faster than broad-leaved species at low temperatures whereas at higher temperatures we expected transpiration to be limited by stomata! conductance. In contrast, the rate of heat loss may be constrained by thick boundary layers in larger leaves at high temperatures. Leaf gas exchange characteristics at various temperatures were correlated with boundary layer thickness, leaf area and specific leaf area for 14 Proteaceae species using phylogenetically independent contrast species. When the temperatures of individual leaves were altered, while ambient temperature was kept at l 8°C, water loss decreased significantly at both 12°C and 30°C with increased leaf size and thus boundary layer thickness. At 30°C, small leaves with thin boundary layers resulted in leaf temperatures below ambient, while larger leaves with thicker boundary layers had leaf temperatures closer to ambient. However, at 30°C the variation in leaf temperature between the smallest and largest leaves was only 3.4°C. Such a small variation in leaf temperature is unlikely to alter temperature-dependent physiological processes. We conclude that the small boundary layer associated with small leaves enables fine-leaved species to transpire at faster rates when water is plentiful. This may be a particularly important strategy for plants that take up most of their nutrients in the wet winter months from nutrient-poor highly leached soils of the CFR region. We suggest that fine leaves are an adaptation for nutrient uptake during winter, although they may also have the benefit of improved coupling of leaf to ambient temperature during the summer drought period.

▼ ENGLISH ABSTRACT: “The twin concepts of sustainability and sustainable development” (Hattingh 2001: 1) have been in international circulation (Hattingh 2001) for thirty years, and yet debate persists about both their meaning and implementation. Essentially, sustainability and its implementation in sustainable development are aimed at curbing our exploitation of the natural environment while endeavouring to share natural provisions more equally among the worlds’ people. It is a conundrum, since sustainability and sustainable development seem to pull in different directions: how, in the context of a growing human population and hence rising demand, are we to reduce our extractions from the natural environment in order to conserve it, while simultaneously maintaining human wellbeing, requiring even greater extractions? Over time a few efforts have been made to conceptualise sustainable solutions, each proposing a different way forward. However, the world remains highly unequal and environmentally degraded. This suggests that, our attempts at sustainability/sustainable development maintain the status quo of a minimalist interpretation where we remain stuck in behaviours unsuited to a changed context. It is evident that sustainability has become a crucial consideration if we wish to safeguard our survival, and the survival of all other species. This said, meaningful action cannot be taken unless the full extent of social, ecological and economic issues is considered, and if the current perspectives on sustainability/sustainable development are critically assessed in terms of their suitability for intervening in our sustainability challenges. In this thesis, the cause of this situation “is explored from an ethical perspective” (Hattingh 2001: 1), and a few “proposals are made on a philosophical level” to “respond to the contested nature of these concepts”, focusing in particular on what kind of an understanding of sustainability/sustainable development we need. Emphasis is directed toward internal “tensions” that shape different interpretations of sustainability, associated with different “ethical positions” (1) that can be taken with regards to questions that address (a) What is so valuable that we ought to sustain it? (b) Why is it so valuable that we ought to sustain it? (c) How should we go about sustaining it? (d) What are the criteria that denote when a state of sustainability has been achieved? Having briefly outlined where tensions are to be found, it becomes possible to show how models of ecologically sustainability can be differently understood. Specifically, the ‘Brundtland Report’ and the ‘Caring for the Earth Report’ are analysed as two influential policy documents subscribing to a strong and moderate anthropocentric stance to sustainability respectively. These reports are critically compared and contrasted with a more ecocentric approach, which characterises the field of deep ecology. The emergent ecosystems services paradigm is also critically evaluated in order to ascertain … Advisors/Committee Members: Woermann, Minka, Hattingh, Johan, Stellenbosch University.

▼ In short term, re-mineralized nitrogen as ammonia can either be conserved in an ecosystem through its complete oxidation to nitrate e.g. 'efficient nitrification' or lost via oxidation to N2 gas e.g., 'inefficient nitrification'. Here, 15N tracers and molecular analyses were used to characterize the 'nitrification efficiency' in relation to aerobic ammonia oxidation, anaerobic ammonia oxidation (anammox) and nitrite oxidation across a range of oxic riverbeds. Here 15NO2- from 15NH4+ was rapidly consumed by anammox/denitrification and/or nitrite oxidation and although the total rate of ammonia oxidation (i.e. 15NO3- + 15N2) was conserved, nitrification efficiency varied from 22.2% to 99.7%. Nitrification efficiency was highest where the contribution from anammox to N2 production (ra) was lowest, and maximal where anammox was absent, suggesting competition between nitrite oxidation and anammox for nitrite. Nitrification efficiency was also highest where the abundance of nxrB gene (Nitrospira + Nitrobacter) was greatest, along with the highest abundance of comammox Nitrospira amoA gene. These results reveal a gradient in riverbed nitrification efficiency that was related primarily to Nitrospira dominating the nitrite oxidizing bacteria (NOB). A preincubation of soluble reactive phosphorus (SRP) selectively increased the degree of nitrification efficiency in some riverbed sediments by stimulating nitrite oxidation. Furthermore, anammox was more important where the abundance of hzsB and amoA genes were greatest, indicating an interaction between aerobic and anaerobic ammonia oxidation. In these oxic riverbeds, aerobic ammonia oxidizing microorganisms (AOM) and anammox bacteria may aggregate together, AOM consumed oxygen at a rate of 22.28 nmol g-1 h-1 and competed with heterotrophic respiration for 8% of the total oxygen consumption, making oxygen limited in the aggregates and thus enabling anammox. Furthermore, the aerobic ammonia oxidation can provide nitrite to sustain the anammox bacteria.

▼ Top predators are recognised as important ecological constituents because empirical studies demonstrate that they can supress populations of herbivores and smaller predators. Despite their important roles, top predators are subject to human-induced population declines globally. The main drivers of decline include habitat loss, habitat modification and human persecution resulting from conflict for resources such as livestock. One outcome of their declines has been a widespread interest in documenting the ensuing ecological effects owing to the fact that top predators are recognised as keystone species. In terrestrial ecosystems, research has shown that top predators can influence ecosystems and their species composition owing to direct effects on smaller predators and their prey species. These direct effects have been linked to far-reaching indirect effects at multiple trophic levels, that extend to vegetation and even the physical attributes of the landscape. The role of top predators is increasingly being viewed as an important component of healthy and functional ecosystems around the world. This thesis explores the hypothesis that Australia’s top terrestrial predator, the dingo (Canis dingo), induces shifts in mammal populations and vegetation in Australian forest ecosystems. The novelty of this thesis is that I test this hypothesis using longitudinal methodologies through time as opposed to snap-shot surveys. In my first chapter, I provide a detailed overview of the current state of knowledge regarding the role of top predators around the world. Specifically, I detail how top predators drive trophic cascades via direct and indirect effect pathways. My second chapter contains comprehensive meta-analyses which investigate the effects of dingo and fox control on mammal species. This provides a robust foundation for identifying knowledge gaps. My third chapter builds on the meta-analysis by conducting a multi-year occupancy analysis in forest ecosystems to determine how dingo control affects the occupancy of invasive mesopredators and native mammals. In chapter 4, I perform generalised linear modelling and quantile regression to improve our understanding of how dingoes supress foxes and to determine if environmental predictors have any bearing on this interaction. Finally, I test if reintroducing a marsupial predator back to mainland Australia can act as a surrogate for the dingo in some parts by restoring some lost ecological interactions to areas where dingoes have been extirpated.

▼ Bioturbation by invasive crayfish can significantly alter sediment properties and its transport in invaded water bodies; however, the indirect impacts of this on ecosystem functioning are poorly understood. In this thesis I present data from mesocosm and field manipulation experiments used to assess the effect of bioturbation by three widely distributed invasive crayfish species (Procambarus clarkii, Pacifastacus leniusculus and Astacus leptodactylus) on a variety of ecosystem properties across seasons. In the mesocosm experiments, P. clarkii caused significantly more bioturbation than the other species, although increased bioturbation by all species in the spring and/or summer was associated with: reduced dissolved oxygen concentrations in near-surface water, indicating a large increase in oxygen demand by the water column; increased methane oxidation potential within the water (MOPwat), indicating the re-suspension of methane oxidising bacteria (MOB) along with the sediment; and a shift in zooplankton community structure towards dominance by large cladoceran species. Stable isotope analysis of the zooplankton showed a strong relationship between δ13C and MOPwat, suggesting that bioturbation increases MOB consumption. Given the importance of zooplankton as a trophic link to the higher food web, crayfish bioturbation may increase the importance of methane derived (chemosynthetic) carbon in invaded ecosystems. Temperature was identified as the key driver of seasonal variations in crayfish bioturbation intensity through laboratory mesocosm experiments, enabling estimation of the full annual pattern of bioturbation intensity for each species. The optimal temperature for P. clarkii was much higher than for the other species meaning that its bioturbation impacts exhibited large seasonal fluctuations whilst P. leniusculus and A. leptodactylus maintained a lower but more consistent level. Field manipulation experiments of enclosed sections of Chalgrove Brook, Oxfordshire, found significant bioturbation activity by P. leniusculus in early autumn; however, the increase in turbidity was too small to detect other effects observed in the mesocosm experiments.

▼ It is important to assess, and fully understand, the mechanisms driving biodiversity responses in urban ecosystems, in order to better preserve, manage-for, and maintain biodiversity in the face of increasing urbanization. Our knowledge of urbanization impacts on biodiversity is predominantly founded on case studies, often lacking spatial and/or temporal rigor, impacting the generalizability of results. Fortunately, broad-scale biodiversity data are being collected by citizen scientists at an unprecedented scale, often biased towards urban areas. Throughout this thesis, I explore the role that citizen science data plays in expanding our knowledge of urban bird ecology. Specifically, I take advantage of these broad-scale data to: (1) assess the applicability of citizen science data to monitor biodiversity changes in urban ecosystems, (2) identify local and landscape attributes of urban greenspaces which predict species richness, (3) discover biodiversity responses to urbanization gradients, (4) demonstrate the species-specific biological and ecological traits which predict a species’ presence in urban ecosystems, and (5) provide methodological enhancements, relying on broad-scale empirical data, to better monitor biodiversity responses to urbanization. Through a multi-faceted approach, I found that: (1) with stringent filtering, unstructured citizen science data revealed comparable patterns to more structured surveys, (2) patch area was the strongest predictor of species richness in urban greenspaces, and tree cover and water cover were strongly associated with landbirds and waterbirds, respectively, (3) across an urbanization gradient, species diversity peaked at intermediate levels of urbanization, likely explained by increased habitat heterogeneity, (4) generalist bird species were the most urban-tolerant, potentially showing high levels of adaptability, and (5) by assigning an urban tolerance score to all Australian bird species based on their distributional response to intensity of urbanization, novel community-level metrics were identified for measuring the success of habitat restoration projects aimed at preserving urban bird diversity. This work transcends previous studies conducted at local scales to provide a global-scale perspective on the response of birds to urbanization, which has practical implications both locally and globally.

▼ Many river ecosystems, especially those in arid and semi-arid, are experiencing severe stress due to the increasing demands on the ecosystem services they provide, coupled with anthropogenic catchment impacts and factors associated with climate change and weather extremes. The flow regime of the Mackenzie River was substantially modified since the construction of a water supply reservoir on its upper reach in 1887. Water is now regulated at several locations downstream of the reservoir, creating a substantially modified flow regime, impacting key environmental values of the river. The river receives an environmental flow allocation and the river channel is used to transfer water dedicated for consumptive use. Water Quality and algal monitoring formed the basis of models that were developed evaluate the ecological condition of this working river under base flow and before, during and after freshes that deliver water to users. Samples of diatoms, soft algae and measurements of water quality were analysed at ten sampling sites for three years (between February 2012 and November 2014) along the MacKenzie River in different seasons and under different flow regimes to understand the spatial and temporal variation in the relationship between algal communities and water quality, and so stream condition. Baseline information on algal communities and water quality was collected during base flow conditions, while experiments on the effect of water releases on algal communities were based on flow regime variations (manipulated flow regimes), specifically on the algae community structure, water quality and ecosystem function. These comprised cease to flow (0 ML/day), low flows (10-15 ML/day), freshes (35-40 ML/day) and high flow (55ML/day) conditions. Physical and chemical characteristics of water, including pH, temperature, turbidity, electrical conductivity, dissolved oxygen, total nitrogen, phosphorus and cations and anions were measured. Biological properties of the algal periphyton communities, including dry mass, ash-free dry mass, chlorophyll-a concentration and species composition, were also measured. Furthermore, the DSIAR (Diatom Species Index for Australian Rivers) score was calculated to classify the condition of the waterway. The results showed the algal species composition changed under different flow regimes along the river. The sensitivity of diatoms to changes in water quality and flow rates deemed them useful indicators of river condition. The results indicated that flows tended to improve DSIAR scores and diatoms versus green algae and cyanobacteria biomass measures in the mid and lower reaches. The biological properties of the algal periphyton communities, and the species composition, varied between sites under different flow regimes. The accumulation of dry mass (not ash-free) decreased downstream during freshes, however the accumulation of AFDM (ash-free dry mass) gradually increased downstream. The results showed that the concentration of chlorophyll-a decreased downstream under water release events. The…

▼ The concept of the ecotone was formalised by Clements (1 905) as a boundary zone between plant communities. Little research exists on the ecological importance or the geographical variability of these zones. Two types of boundaries are acknowledged: the ecotone and the ecocline. The ecotone is a sharp boundary; the ecocline a gradual boundary. The term 'transitional area' is proposed here to more accurately describe these areas as this research demonstrates that a complex continuum exists between the two end points. Additionally, mosaics often complicate the nature of the transition and may form a boundary type in their own right. Upland plant communities represent important semi-natural habitats within the British Isles. Effective management depends on an understanding of their structure and function. This research is primarily concerned with the description of structure (spatial pattern and variability in floristic composition) but explanation of these patterns is only possible through an understanding of function (vegetation dynamics). Pilot studies determined an appropriate methodology for studying transitional areas. The approach progressed from a linear transect to a two-dimensional rectangular transect. The pilot studies also evaluated a range of methods for data analysis. Extended field sampling followed which included 23 sites in 4 locations: Dartmoor, Snowdonia, North York Moors and Barra, Western Isles of Scotland. Data analysis exposed the complexities of the transitional areas sampled but 'noise' often obscured the true characteristics. To overcome this a Species Ratio Index Model was devised to identify the strength of signal for each boundary. The final characterisation of transitional areas is based on three main components: ecotone, ecocline and mosaics, each displaying varying amplitude. Of the sites sampled, few boundaries revealed single characteristics and the majority were far more complex than their observed patterns implied. On the basis of this characterisation a classification is proposed which incorporates both natural and anthropogenic factors. The classification represents an important contribution to the understanding of boundary types. This study reinforces the significance of boundaries in the landscape. The potential for future research is great, particularly through the development of a predictive model for management purposes.

▼ Üks liigirikkamaid õistaimede sugukondi on orhideelised ehk käpalised, mille liigid moodustavad tihedaid seoseid nii putuktolmeldajate kui ka seenjuurt moodustavate seentega. Orhideede mükoriisa erineb teistest mükoriisatüüpidest nii anatoomiliselt, seentaksonite poolest kui ka funktsionaalselt. Käpalised on seotud mükoriisa seentega alates seemnete idanemise faasist, kuna nende seemned on tolmpeened ning ilma idanemiseks piisavalt vajalike toitaineteta. Samas jäävad mükoriisa seened mängima olulist rolli ka hiljem, kui orhideedel arenevad rohelised lehed ja fotosünteesivõime. Arvatavasti aga muutub seensümbiotide esinemine ning kooslus täiskasvanud orhideede juurtes vegetatsiooniperioodi vältel. Tavaliselt on rohelised, s.o fotosünteesivad orhideed seotud mullas leiduvate saproobidega sugukondadest Tulasnellaceae ja Ceratobasidiaceae ning seltsist Sebacinales. Nimetatud saproobide ökoloogiat ning esinemist mullas on seni vähe uuritud. Antud doktoritöö käigus uuriti fotosünteesivate orhideeliikide mükoriisa seenekoosluste ajalisi ja ruumilisi mustreid. Töö eesmärgiks oli välja selgitada, 1) kuidas muutuvad ühe vegetatsiooniperioodi vältel täiskasvanud orhideedega seotud seensümbiontide kooslused, 2) kas seensümbiontide kooslused on mõjutatud kasvukohatüübist, 3) kas seensümbiontide rohkus on mõjutatud orhidee lähedusest ning 4) millised on nende seenekoosluste ruumilised mustrid. Lisaks oli eesmärgiks arendada seente globaalsel geenijärjestustel põhineva määraja UNITE referentsandmebaasi. Doktoritöö peamisteks tulemusteks on, et orhideede mükoriisaseente kooslused on esmalt mõjutatud orhideeliigist ning seejärel kasvukeskkonnast ning orhidee arenguetapist. Loopealsetel on orhideede mükoriisaseened mullas levinud juhuslikult ning üldjuhul ei mõjuta nende seente arvukust mullas kaugus peremeestaimest. Andmebaasi täiendamisel leiti, et avalikes andmebaasides esineb mitmeid orhideede mükoriisaseente DNA järjestusi, mis on ebakvaliteetsed ning mille kohta puuduvad metaandmed.; Orchids represent one of the largest plant families and display tight associations with pollinators and mycorrhizal fungi. Orchid mycorrhizal (OrM) symbiosis is unique anatomically, taxonomically as well as functionally. Mycorrhizal fungi play a vital role for the orchids during their germination by providing essential nutrients to the dust-like orchid seeds that are almost devoid of their own food reserves. Even after orchids have developed green leaves and start photosynthesizing, their roots remain colonized by mycorrhizal fungi. However, the abundance of fungal colonization as well as the fungal community composition presumably change in the roots of the mature orchids during the vegetation period. Typically, photosynthetic, autotrophic orchids associate with saprotrophic fungi from the Ceratobasidiaceae, Tulasnellaceae and Sebacinales. So far, the distribution and ecological requirements of these fungi remain poorly explored. The aim of this thesis was therefore to study the temporal and spatial patterns of orchid mycorrhizal fungi in forest… Advisors/Committee Members: Kõljalg, Urmas, juhendaja (advisor), Kull, Tiiu, juhendaja (advisor).

▼ The unprecedented degradation of freshwater ecosystems due to the rampant exploitation of water resources re-establishes the importance of preserving freshwater ecosystems in order to ensure their continued viability that supports the attainment of sustainable development. This concern is addressed in Article 20 of the 1997 Watercourses Convention that specifically provides for the preservation of ecosystems of international watercourses. However, the interpretation and the subsequent application of this obligation are complicated by the proliferation of international instruments concerning the environment, which leads to the fragmentation of international law. In response to the apprehension raised over the undesirable consequences of the fragmentation of international law, the potential of Article 31(3)(c) of the 1969 Vienna Convention as an interpretative mechanism that enables the systemic integration of rules has come into the limelight. The objective of the present thesis, titled ‘Preservation of Ecosystems of International Watercourses and the Integration of Relevant Rules’ is to develop a interpretative framework for the operationalisation of Article 31(3)(c) that allows the full realisation of its potential as a tool of integration. A three-tier operationalisation framework that re-interprets the salient features of Article 31(3)(c) through the prism of an interactional understanding of international law is developed and executed through Chapters Two to Eight, where Chapter Nine provides a general conclusion of the thesis. The reconstruction of existing interpretation of Article 31(3)(c) provides a new understanding of this Article, which enables the realisation of its systemic integration potential. The application of this framework of operationalisation in the interpretation of the obligation to preserve ecosystems of international watercourses stipulated under Article 20 reflects contemporaneous development in international environmental law, and enhances the normative content and scope of Article 20.

Mediterranean riverine systems show distinct features due to their marked seasonal pattern. Species present in these environments developed specific functional adaptations to cope with this variability linked to events like floods, droughts and geomorphic natural disturbances. Widespread river and floodplain alteration across Mediterranean regions, turned restoration and rehabilitation of riparian corridors a subject of increasing interest during the last decade. Yet, the complex dynamics of riverine Mediterranean systems and their vegetation communities’ interaction is still under study. Improving our understanding on species functional responses to environmental variability will contribute to successful restoration/rehabilitation through more ecologically and economically efficient projects. It was hypothesized that tree growth is affected by water availability and that trees have higher growth near the water channel and downstream from the river source. In this dissertation, dendrochronology was used to study past tree growth in Fraxinus angustifolia Vahl trees from Odelouca river, in Algarve. Annual growth was analyzed in groups differing in their relative position to the active river channel and distance to catchment source, and analyzed with hydrological, climatic and edaphic factors. Tree position relative to active river channel showed to have the highest impact on mean raw tree growth during the last four decades, followed by soil C/N ratio. High minimum temperature during autumn extended the growing season, a trend associated with climate change and temperature rise in the last three decades in the Mediterranean. Additionally, discharges during spring created favorable conditions when tree growth was more intense. Establishing optimal growth position and ecological conditions for riverine species is important to define principles and guidelines for restoration and rehabilitation projects. Also, global change plays an important role in modulating future responses of vegetation under a changing climate, so understanding past responses can provide important clues for adaptive management
