▼ 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’.

▼ Abstract An ethnobotanical study was conducted from February to March 2008 to investigate the traditional uses and system of managing of the Dess’a forest by people in and around the forest. The aim of this study was to identify and document the traditional knowledge held by the local people in using and managing the forest resources. Seven forest Kushtes (village) very close to and within the forest area were purposively selected. Ninety-two informants comprising of 74 % (68) males and 26% (24) females were randomly selected for the study. Based on the community recommendations fifteen key informants with 73 % (11) males and 27 % (4) females were selected purposefully. Information was collected using semi-structured interview, direct matrix ranking and scoring, preference raking, pair wise ranking and focus group discussion. A total of 82 plants belonging to 65 genera and 43 families were recorded. The families best represented were Fabaceae (6 species), Lamiaceae and Solanaceae (5 species each) and Tiliaceae (4 species). Based on the results from the informant consensus, Olea europaea subsp cuspidata and Acacia etbaica are the most popular among the local people for their value. The results further indicated that the use categories animal fodder and bee forage scored 68% each followed by firewood 45%. Of the utilized growth habits shrubs account 62.19%. The most frequently used plant parts were leaves and nectar/pollen 20.89% each followed by stem 19.40%. The species O. europaea subsp cuspidate, A. etbaica, Boscia salicifolia, Erica arborea and Cordia africana are the 1st, 2nd, 3rd and 4th multipurpose forest plants respectively. The findings showed that the local people have held forest management systems through unique grazing area strategies for plough-oxen and open access to all other livestock. The forest trees are also used to hang beehives. The forest resources are exclusively held by the community and no external bodies are allowed to use which is important in biological conservation. Fire hazard, fuelwood collection and use of building materials were ranked 1st, 2nd and 3rd priority management problems in the study area. Based on the informants’ perception, Erica arborea, Boscia salicifolia and Cordia africana and Dracaena ellenbeckiana are the first, second and third locally threatened species respectively. The study generally shows the local people depend on the forest for their livelihoods. Currently, the traditional forest management is eroding due to population growth, which negatively affects the forest protection and management. Therefore, this study has tried to find out the traditional forest resource xi management systems and the main forest management problems and can contribute for the development of new forest management plan and forest protection strategies.

▼ This study describes the isolation and characterisation of microsatellite loci in Forbes’ parakeet (Cyanoramphus forbesi). These molecular markers are used to assess the status of interspecific hybridisation between Forbes’ parakeets and Chatham Island Red-crowned parakeets (C. novaezelandiae chathamensis) on Mangere and Little Mangere Islands in the Chatham Islands group. The evolution of these microsatellite loci in parrots is also investigated. Forbes’ parakeets are facing the problem of genetic introgression due to extensive hybridisation with Chatham Island Red-crowned parakeets. Hybrids show a spectrum of crown morphologies between the parent species (Nixon 1982), but identification of hybrids based on morphology alone is not foolproof. Mitochondrial DNA studies by Boon (2000) showed that Forbes’ parakeet is a distinct lineage, basal to all other New Zealand parakeets but several Forbes’ morphotypes have Chatham Island Redcrowned parakeet haplotype. However, mitochondrial DNA markers only probe the maternally inherited lineages and cannot tell the whole story. The microsatellite markers used in this study show that interspecific hybridisation between Forbes parakeet and Chatham Island Red-crowned parakeet is more extensive than previously expected. Microsatellite data combined with results from scoring mitochondrial DNA haplotypes show that crown morphology alone under-represents the proportion of hybrids in the population, and that a large number of cryptic hybrids (77.9%) show Forbes’ parakeet morphotypes. A three factor scoring system is suggested in which a parakeet must pass both genetic (microsatellites and mitochondrial) and morphological criteria to be considered a “pure” Forbes’ parakeet. Using this system, 17.8%, 1.2%, and 81.0% of the Mangere Island parakeet population are “pure” Forbes’ parakeets, “pure” Chatham Island Red-crowned parakeets, and interspecific hybrids respectively. The results of this study have implications for the future conservation of Forbes’ parakeet. Because interspecific hybridisation makes no positive contribution to the long-term survival of Forbes’ parakeets, conservation measures to limit contact between the two species should be taken to control further hybridisation of parakeets on Mangere Island. The microsatellite loci isolated in this study are found to evolve following the patterns best described by either the Stepwise Mutation Model (SMM; Ohta & Kimura 1973) or the Two-Phase Model (TPM; Di Rienzo et al. 1994) at population level. By mapping the evolutionary changes in repeat motif variations to a parrot phylogeny, it is suggested that these loci may evolve through a more complex model than sole repeat number changes.

▼ The Australian arid zone has the highest recent mammal extinction rate in the world with most species in the critical weight range of 35 g to 5.5 kg now regionally or globally extinct. Reversing arid zone mammal decline has become a major focus for conservation organizations and reintroduction programs are a common tool in species recovery. Unfortunately, reintroduction success in Australia is low and predation from introduced cats and foxes is commonly cited as the cause of reintroduction failure. In this thesis, I aimed to improve reintroduction success in the arid zone by exploring predation, release protocols and post release abundance at the Arid Recovery Reserve in northern South Australia. Firstly, I attempted to reintroduce threatened mammal species into both a predator free area and one where predators were controlled. Results suggested that successful reintroductions only occurred when cats and foxes were excluded. I then tested different predator reduction strategies to determine if reintroduction success could be improved, including aerial baiting, strategic bait placement and the use of a native top-order predator. Although the use of dingoes to control foxes and cats showed promise, I was unable to improve reintroduction success using poison baiting as it did not significantly reduce feral cat abundance. I investigated the role of release strategies on reintroduction success and conducted predator avoidance training, soft and hard releases and using captive versus wild stock. Predator avoidance training did not assist long term reintroduction success of the bilby but some behavioural differences were detected. Results suggest that Australian arid zone species may be able to learn predator avoidance behavior but this may not necessarily translate into improved reintroduction outcomes. The use of soft and hard releases and captive and wild stock had little effect on reintroduction success when cats and foxes were excluded. Interspecific differences in post-release mortality and behaviour indicated that soft releases may be useful at unrestricted release sites, in situations of high predation risk and where social, sedentary species which invest heavily in their shelters are being released. Finally, I analysed long term monitoring data for four reintroduced threatened species to determine whether factors such as rainfall, time since release or temperature influenced postrelease population fluctuations. Factors significantly influencing abundance included the Indian Ocean Dipole and temperature. Time since release was still the most important factor influencing abundance even 10 years after release indicating that reintroduced populations may not stabilize for decades and long term monitoring is essential. Regardless of reintroduction protocols, new methods of broadscale cat control are required before broadscale reintroduction success can be improved in the Australian arid zone. Present control methods are insufficient to enable successful reintroductions of cat-sensitive mammal species without exclusion… Advisors/Committee Members: Paton, David Cleland (advisor), School of Earth and Environmental Sciences (school).

▼ Phytophthora dieback, caused by Phytophthora cinnamomi Rands, affects a wide range of Australian native plants. In South Australia, the pathogen has affected large areas of native vegetation to threaten plant biodiversity. Lack of information on the disease in the local environment hampers management. The main objectives of this project were to: a) determine the rate of pathogen and disease spread in naturally infested native vegetation, b) assess the susceptibility of plant species native to South Australia to the disease and c) assess ability of antagonistic soil actinomycetes to protect susceptible species from Phytophthora dieback. A confirmed P. cinnamomi-infested site, with gentle slope, at Mount Bold Reservoir Catchment Reserve in the Mount Lofty Ranges, was selected to assess pathogen and disease spread in native vegetation. The soil was loamy sand. The vegetation was open woodland dominated by Eucalyptus obliqua L’Hérit with an understorey dominated by Xanthorrhoea semiplana F. Muell, a highly susceptible species which was used as an indicator to assess disease spread. An area of 70 m x 70 m, extending from two disease fronts into the adjoining healthy vegetation, was marked into 10 m x 10 m quadrats. The number of dead and dying X. semiplana was counted and soil samples from each quadrat, collected every spring and autumn from 2008 to 2010, were baited for P. cinnamomi using cotyledons of E. sieberi L.A.S. Johnson. P. cinnamomi was regularly detected along the disease front. However, the pathogen did not spread across the slope into the adjoining healthy vegetation despite annual rainfall of 626 to 900 mm for three consecutive years (2008 to 2010). The slow spread of the pathogen was reflected in the small numbers of dead and dying X. semiplana observed in each quadrat at each assessment time. The limited spread of the pathogen may be due to unfavourable weather conditions. In winter (June to August), when the precipitation was high (ca. 50% of the annual rainfall), soil temperature was generally too low (average temperature 9.3°C) for formation of sporangia. On the contrary when the temperature was warm (≥ 15°C) during spring (September to November) and autumn (March to May), the average soil water potential, ≤ -200 kPa, may have been too low for movement of zoospores. Further, sporadic distribution of P. cinnamomi and the patchiness of disease spread might have reflected the efficiency of the baiting technique. Thirty-seven South Australian native plant species, including 15 threatened or locally endangered species, were assessed for susceptibility to Phytophthora dieback in a greenhouse from October 2009 to July 2010. Seedlings or cuttings were raised in potting mix for native species then transplanted to 15 cm-diameter pots filled with limed University of California mix or Bio Gro® (Bio Gro, South Australia). Plants were inoculated with P. cinnamomi via pine wood-inoculum plugs when up to 6 months old, maintained in moist conditions and monitored for disease symptoms for 3 to 6 months.

▼ Styrax americanus Lam. (American snowbell) is an ornamental tree or shrub seldom used in the nursery industry. The species is common in the southeastern United States and is distributed continuously as far north as southeastern Virginia and southern Illinois. We studied a small, threatened population in northern Illinois (latitude = 41y10N), about 500 km disjunct from populations to the south. Little is known about the genetic diversity and landscape potential of this species. The first objective was to evaluate the genetic structure of the northern disjunct population and compare those individuals genetically to populations from the northern and southern extremes of the continuous range in southern Illinois and Florida, respectively. Percentage of polymorphic loci of the disjunct population was 64%, greater than that of the population in Florida. We propose that the diversity of the disjunct population is a consequence of its history as a component of the Grand Marsh that existed in the region until about 100 years ago. The second objective was to evaluate variation in floral morphology among plants from populations that span the distribution of S. americanus grown in a common environment. Results suggest that plants from Illinois have larger flowers than plants from Florida, new knowledge about phenotypic variation of traits with both horticultural and ecological implications. The third objective was to evaluate the tolerance of S. americanus to water deficit and partial flooding, and to determine how soil-water status affects cold tolerance during cold acclimation. Across hydration treatments, there were no provenance differences in CO2 exchange rates between the northern Illinois and Florida populations. Results suggest that plants exposed to prolonged water deficit exhibit less cold tolerance than well hydrated plants. This study provides initial evidence of a dynamic interplay of moisture supply and cold hardiness. Finally, the fourth objective was to characterize this species' capacity to resist deacclimation. Analyses suggest that plants from Florida deacclimated more rapidly in April than plants from Illinois. Selection of germplasm from the Illinois populations appears advantageous for horticultural applications in regions with harsh winters due to the greater mid-winter hardiness, and particularly the capacity of the northernmost population to resist deacclimation.

▼ The current study was undertaken to explore the relationship between self-esteem, narcissism, and empathy with intimate partner violence perpetration among men in 2 samples: college students and inmates. The sample was analyzed both as an aggregate and separately. A negative relationship was hypothesized between intimate violence perpetration and both self-esteem and empathy. A positive relationship was expected between intimate violence perpetration and narcissism. A 2-way interaction was examined between self-esteem and narcissism as a test of threatened egotism, defined as high self-esteem coupled with high narcissism, which was not expected in the current study. Empathy was hypothesized to moderate the relationship between intimate violence perpetration and threatened egotism, such that low empathy coupled with high narcissism and high self-esteem was expected to result in increased intimate violence perpetration. Participants were 488 men (249 college students; 239 inmates). Surveys consisted of a demographic questionnaire, CTS2 for participants’ relationships, CTS for their parents’ relationship, Rosenberg Self-Esteem Scale, entitlement and exploitative subscales of the NPI, and the IRI. Independent samples t-tests were used to explore differences in the 2 samples. Hierarchical multiple regression was undertaken in the aggregate sample as well as the college sample and inmate sample separately. For the aggregate sample significant main effects emerged for family violence, self-esteem, narcissism, and cognitive and affective empathy, as well as the 2-way interaction between self-esteem and narcissism. Results were similar for the college sample with the exception that affective empathy was not significant. For the inmate sample main effects emerged for family violence, narcissism, and affective empathy as well as the 2-way interaction between self-esteem and narcissism. The results appear to support the theory of threatened egotism, though further analysis indicates the findings are not so clear. Empathy did not moderate the 2-way interaction between self-esteem and narcissism.

▼ Worldwide, species are being driven to extinction due to anthropogenic activities that have led to habitat loss and modification, introduced species, over exploitation, pollution and climate change. As a result, species are now being reintroduced back into their former ranges, but many of these reintroductions fail. The eastern barred bandicoot Perameles gunnii, a threatened marsupial restricted to lowland grasslands in south-eastern Australia, has had many failed reintroduction attempts. This study aimed to improve the success of future eastern barred bandicoot reintroductions and expand our knowledge of this species’ ecological requirements to ensure its long term survival. I reviewed all previous eastern barred bandicoot reintroductions, determining how best to monitor bandicoots, analysing data from two different populations to find out the regulatory processes acting upon them and, examined how habitat quality influences the behaviour of bandicoots. Since 1989 the eastern barred bandicoot has been reintroduced into eight sites: Woodlands Historic Park, Hamilton Community Parklands, Mooramong, Floating Islands Nature Reserve, Lake Goldsmith Wildlife Reserve, Lanark, Cobra Killuc Wildlife Reserve, and Mt Rothwell. All reintroduced populations initially increased, but declines were observed during the mid to late 1990s, culminating in extinctions at many sites. Although the exact cause of these declines is not known, a combination of drought and predation by red foxes Vulpes vulpes and cats Felis catus is thought to be responsible. Monitoring threatened species is essential for determining growth trajectories and the response of populations to any management actions undertaken. I compared the effectiveness of three low-cost monitoring techniques in a low density, declining population, and in a relatively high density population. Trapping was suitable for monitoring only the high-density population, whilst spotlighting detected few bandicoots in both populations. Foraging dig counts were readily identified and counted at both reserves, with the density of digs being greater in the winter months. Using these three techniques together increased the probability of bandicoot detection, and identified the growth trajectory of the population and spatial occupation of the reserve. Using data collected from live trapping, I analysed a 17-year data set of a reintroduced population not protected by a predator-barrier fence. This population showed some evidence of an Allee effect. Two measures of fecundity showed negative density dependence, whilst high air temperature negatively affected breeding and litter size. The main cause of population regulation at this site is likely to be predation by introduced red foxes, exacerbated by a prolonged drought in the mid 1990s. I also analysed a smaller data set (2.5 years) collected from a newly-reintroduced population. This population also showed some…

▼ The conservation and management of biodiversity has become increasingly sophisticated and this has led to the development of new tools and methods, such as computer programmes to analyse data and modelling approaches to compare different management scenarios and evaluate their potential effectiveness (Kareiva & Levin, 2003). Conservation efforts depend on knowledge, availability of resources, management planning and a willingness of the government and community to commit to long-term recovery actions (National Biodiversity Strategy Review Task Group (NBSRTG), 2009). Currently, New Zealand legislation that specifically addresses threatened species at a national level in New Zealand, such as the Wildlife Act 1953 and the Conservation Act 1987 are outdated in managing the threats our endangered species face. Adopting more robust legislation, such as that found in Australia (the Environment, Protection and Biodiversity Protection Act 1999), or in the United States of America (the U.S. Endangered Species Act 1973) could help the Department of Conservation reduce the numbers of endemic species being added to the threatened species list and aid in recovery planning for the future. This research assesses New Zealand‟s threatened species recovery plans and compares them with national threatened species recovery plans in Australia. New Zealand has recovery plans for only 50 species despite the fact that there are some 2800 species classified as threatened and facing potential extinction (Department of Conservation (DOC), 2010a). Analysing what currently exists in management plans is one way in which to determine what planning has taken place and how an organisation is planning for the future (Sattler & Creighton, 2002b). The lack of review of existing plans is in itself an impediment to improving future plans (Clark, Reading, Clarke, 1994; Clark, Hoekstra, Boersma, Kareiva, 2002). A review of New Zealand‟s endangered species recovery plan programme indicates that if threatened species recovery efforts are to be successful in the future, there needs to be a review of existing recovery plans; increased advocacy in the community; and legislation at the national level should be revised and enforced.

▼ Butterfly numbers are declining worldwide primarily due to habitat loss and habitat degradation, resulting in many species now being classified as threatened. Many butterfly species are further endangered by the additional threats of fragmentation, agricultural chemicals, climate change and introduced predators. In Tasmania, Australia, the threatened ptunarra brown butterfly (Oreixenica ptunarra) has recently come under threat from predation by introduced vespid wasps, which have the potential to further reduce their numbers, possibly causing local extinctions. The nature of this new threat and possible conservation actions to mitigate it are the subject of this thesis. The present study investigated whether vespid wasps were having a significant impact on O. ptunarra numbers, ways of controlling the wasps or excluding them from O. ptunarra’s habitat, and methods of creating new populations of O. ptunarra by translocating individuals within its historical range. Vespid wasp control was performed by using toxic baits containing fipronil, as well as directly poisoning wasp nests. Transect surveys to count vespid wasp and O. ptunarra numbers performed at wasp control sites and monitoring sites, were compared to determine whether the wasp control was effective and whether the wasps were having a negative effect on O. ptunarra numbers. Vegetation transect surveys were also performed at sites with and without O. ptunarra to determine the relationship between flora species and O. ptunarra numbers and which species O. ptunarra prefers. Translocations of O. ptunarra were attempted by moving female imagoes and eggs to suitable sites within the species’ historical range to create new, self-sustaining populations. The buffer size necessary to exclude wasps from O. ptunarra habitat was also investigated by analysing the vegetation around the Poa grasslands that comprise O. ptunarra’s habitat at various buffer distances, using GIS. The vegetation analysis was compared to vespid wasp and O. ptunarra numbers to determine which vegetation types affected their numbers and the buffer size required to exclude wasps from O. ptunarra habitat. It was determined that vespid wasps were having a negative impact on O. ptunarra numbers and that, when wasp numbers were controlled, O. ptunarra numbers rose marginally. Unfortunately, wasp numbers were not decreased enough to protect O. ptunarra sufficiently, suggesting that wasp control efforts need to be increased. O. ptunarra was successfully translocated to one of four release sites, with a persistent population of butterflies being detected in the following four years. Analysis of the vegetation composition at the sites determined that O. ptunarra preferred sites containing the species Poa labillardierei and P. hiemata and a high abundance of flowering nectar plant species. These attributes should be taken into consideration during the selection of potential sites for future translocations of O. ptunarra. The buffer analysis determined that plantation forests were having a significant…

▼ Species and ecosystems worldwide are threatened by human activities, and intensive conservation efforts are needed to slow the ongoing biodiversity crisis (Tittensor et al. 2014). Islands are crucial to the conservation of global biodiversity: in just 5.5% of the earth's land area, they contain a disproportionate amount of terrestrial species, including an estimated 19% of birds and 17% of rodents. Islands are also highly vulnerable to human impact; 77% of known terrestrial vertebrate extinctions have taken place on islands and 40% of critically endangered species currently inhabit them (Tershy et al. In press). The leading cause of extinction and endangerment on islands is introduced species (Tershy et al. In press). In particular, animals associated with humans, such as such as rats, mice, pigs, goats, rabbits, and cats, have become feral on a large percentage of the world's roughly 400,000 islands (Atkinson 1985). These invaders have a myriad of direct and indirect effects on insular species, such as overgrazing of native plants, predation of native animals, competition with natives for food and other resources, and alteration of important physical and chemical ecosystem processes (Croll et al. 2005, Towns et al. 2006, Fukami et al. 2006, Kurle et al. 2008, Spear and Chown 2009, Simberloff 2011, Medina et al. 2011).The eradication of invasive mammals from islands is an increasingly utilized conservation tool with a strong record of mitigating or reversing much of the damage caused by invasions (Barun et al. 2011a). Nearly 1,100 successful eradications to date have removed invasive mammals from 750 islands globally (DIISE 2014). Ongoing developments in eradication technologies are creating opportunities to eradicate invasive vertebrates from increasingly large and complex islands (Howald et al. 2007, Burbidge 2011, Campbell et al. 2011). Consequently, national and regional government agencies and conservation organizations are increasingly investing in vigorous eradication programs on islands. However, the global scale of island invasions greatly outweighs the resources available to undertake eradication projects. To ensure that biodiversity conservation resources are allocated as effectively and efficiently as possible, islands must be prioritized for eradications.In my dissertation I address the island prioritization problem comprehensively. First, I develop a statistical model that explains global island extinctions as a function of invasive mammal presence, native taxonomy, and island attributes (Chapter 1). I use this model to isolate and quantify the impacts of invasive mammals on globally threatened island vertebrate species, and to predict the benefits to these species from invasive mammal eradication. Then, I combine these predicted benefits with eradication cost estimates, and develop an optimization model that identifies sets of islands where specified conservation goals can be attained via eradication for the minimum cost (Chapter 2). Finally, I assess the importance of socio-political factors in global…

As regiões tropicais têm sofrido drásticas modificações na paisagem ao longo do tempo. No Brasil, o bioma Cerrado é considerado um dos mais vulneráveis devido à crescente destruição ocasionada pela ação antrópica, sendo o bioma mais ameaçado do mundo. Restam apenas 20% da cobertura original do Cerrado em todo o país e somente 2,2% estão inseridos em áreas protegidas. Com essa crítica situação de conservação, além da rápida destruição de seus hábitats naturais e também por possuir uma elevada riqueza biológica, o Cerrado foi incluso entre os 25 hotspots mundiais. A redução excessiva das áreas nativas pode provocar a extinção de muitas espécies de aves, principalmente espécies especialistas de áreas campestres. Em aves, a seleção de hábitat é entendida como um processo hierárquico de respostas comportamentais que influenciam a sobrevivência e a aptidão dos indivíduos. A diminuição de sítios adequados para a nidificação no ambiente pode ser um fator crítico que determina a extinção local de muitas espécies de aves. Outro aspecto de extrema importância, é a compreensão de fatores relacionados à história de vida das espécies. Descrições detalhadas sobre a biologia reprodutiva da avifauna são de fundamental importância, ainda mais que muitas das espécies de aves neotropicais ainda não possuem descrições sobre informações básicas de suas histórias de vidas. Diante disso, visamos no capítulo I descrever a biologia reprodutiva de Alecturus tricolor e Sporophila pileata, dois Passeriformes dos quais muito pouco se sabe sobre aspectos fundamentais das suas histórias de vida. No capítulo II visamos entender como algumas aves de fitofisionomias campestres de cerrado selecionam o microhábitat para a nidificação e como essas escolhas podem influenciar no sucesso reprodutivo dessas espécies

Tropical regions have undergone drastic changes in the landscape over time. In Brazil, the Cerrado is considered one of the most vulnerable biomes due to increased destruction caused by human action; it is the most threatened biome in the world. Only 20% of the original cover of the Cerrado remains across the country and only 2.2% is included in protected areas. With this critical conservation situation, the rapid destruction of their natural habitats along with its high biological richness, the Cerrado has been included among the 25 global \"hotspots\". Excessive reduction of native areas can cause the extinction of many bird species, principally species specific to grassland areas. Among birds, the habitat selection is understood as a hierarchical process of behavioral responses that influence the survival and fitness of individuals. The reduction of suitable nesting sites in the environment may be a critical factor that determines the local extinction of many species of birds. Another very important aspect is the understanding of factors related to the life history of the species. Detailed descriptions of the reproductive biology of birds are of fundamental importance, even more so since many of neotropical birds still do not have…

▼ Abstract The natural diversity of Earth consists of two main elements: the diversity of biotic nature (biodiversity) and the diversity of abiotic nature (geodiversity). Their relationship is theoretically strong but insufficiently studied. A conservation principle called Conserving Nature’s Stage (CNS) states that geodiversity (e.g. data on geological, geomorphological and hydrological richness) could be used as a coarse filter strategy for conserving biodiversity in changing environmental conditions. It is based on an idea that areas where geodiversity is high are capable of supporting high biodiversity, because organisms depend on the abiotic “stage” on which they exist. The capability of present conservation actions to protect and sustain biodiversity in the face of global change is under debate, and CNS is proposed as one complementary solution to this issue. There is an urgent need for studies that examine the relationship between geo— and biodiversity to assess the possibilities of CNS for nature conservation. In this thesis, I explored the potentiality of how geodiversity information can be used in assessing biodiversity by examining their relationship in different areas, at different spatial scales and with different measures. This thesis consists of three studies: (1) a study where the importance of geodiversity, topographical and climatic variables to threatened species diversity and rarity was analysed, (2) a study where geodiversity and vascular plant species richness were examined at different land-use intensity (hemeroby) levels, and (3) a study where landforms were evaluated based on their vascular plant diversity. My most important goal was to determine how landforms and landscape-scale geodiversity (i.e. variables for which the geological, geomorphological and hydrological feature richness are accounted) are related to biodiversity (i.e. the species diversity and rarity of vascular plants and other taxa). The results highlighted the overall positive relationships between geo- and biodiversity in high-latitude environments. Geodiversity variables had consistent positive effects on threatened species richness, especially for threatened vascular plants. Of geodiversity variables, geomorphological richness was the most important predictor for most taxa, indicating that the landscape-scale variability of landforms plays an important role in determining threatened species richness patterns. Independent geodiversity contributions for vascular plant species richness were highest in pristine environments throughout Finland, and geodiversity land-use intensity relationships were mainly negative. Landforms were, in general, more diverse than control sites and there was notable variation in plant species diversity between different landforms. Gullies and river shores were the most diverse landforms at alpha and gamma diversity levels, whereas aapa mires were taxonomically the most unique (i.e. they had the highest beta diversity). To conclude, geodiversity added explanatory power for biodiversity models and… Advisors/Committee Members: Hjort, J. (Jan), Alahuhta, J. (Janne), Kalliola, R. (Risto).

▼ Freshwater turtles are a globally declining taxa, and estimates of population status are not available for many species. Primary causes of decline stem from widespread habitat loss and degradation, and obtaining spatially-explicit information on remaining habitat across a relevant spatial scale has proven challenging. The discipline of remote sensing science has been employed widely in studies of biodiversity conservation, but it has not been utilized as frequently for cryptic, and less vagile species such as turtles, despite their vulnerable status. The work presented in this thesis investigates how multi-temporal remote sensing imagery can contribute key information for building spatially-explicit and temporally dynamic models of habitat and connectivity for the threatened, Blanding’s turtle (Emydoidea blandingii) in southern Ontario, Canada. I began with outlining a methodological approach for delineating freshwater wetlands from high spatial resolution remote sensing imagery, using a geographic object-based image analysis (GEOBIA) approach. This method was applied to three different landscapes in southern Ontario, and across two biologically relevant seasons during the active (non-hibernating) period of Blanding’s turtles. Next, relevant environmental variables associated with turtle presence were extracted from remote sensing imagery, and a boosted regression tree model was developed to predict the probability of occurrence of this species. Finally, I analysed the movement potential for Blanding’s turtles in a disturbed landscape using a combination of approaches. Results indicate that (1) a parsimonious GEOBIA approach to land cover mapping, incorporating texture, spectral indices, and topographic information can map heterogeneous land cover with high accuracy, (2) remote-sensing derived environmental variables can be used to build habitat models with strong predictive power, and (3) connectivity potential is best estimated using a variety of approaches, though accurate estimates across human-altered landscapes is challenging. Overall, this body of work supports the use of remote sensing imagery in species distribution models to strengthen the precision, and power of predictive models, and also draws attention to the need to consider a multi-temporal examination of species habitat requirements.

▼ Many threatened and invasive species occupy collections of spatially separated populations subject to local extinction and colonisation, known as metapopulations. Although they occur naturally, metapopulations are becoming increasingly prevalent throughout the world due to habitat loss and fragmentation. To increase the persistence of threatened metapopulations, or decrease the persistence of invasive ones, managers must decide how, where and when to spend limited resources across space and time. In this thesis, I integrate quantitative models with decision theory to predict the persistence of metapopulations in response to management alternatives. This thesis is divided into six chapters. The first chapter provides a general introduction to metapopulations and decision theory. The second chapter explores when, where and how to manage threatened metapopulations when the dynamics of these networks are poorly understood. Adaptive management has been applied to ecological problems containing considerable uncertainty, but is yet to guide the restoration of metapopulations. I develop a framework to optimally manage metapopulations using adaptive management when there is uncertainty in the rate of colonisation between patches. I develop a case study for the threatened bay checkerspot butterfly (Euphydryas editha bayensis) and demonstrate how best to manage the population while learning about its dynamics over time. The third chapter examines when to add a patch to a threatened metapopulation to compensate for destruction of another due to urbanisation or agricultural development. I develop spatially explicit metapopulation models for two threatened Australian species – the growling grass frog (Litoria raniformis) and the southern emu-wren (Spititurus malachurus intermedius) – and determine when it is optimal to add a patch to each metapopulation if the budget available to managers accrues interest over time. I find that there are many occupancy states of each metapopulation where it is optimal to delay habitat creation until well-after habitat destruction has occurred. The second half of this thesis focuses on invasive metapopulations. Chapter 4 develops a rule for determining when to increase the colonisation rate of metapopulations susceptible to three types of threat – an abiotic threat (i.e. fire, flood or drought), a generalist threat, and a specialist threat (i.e. predators, pathogens or disease). When considering habitat corridors as a management strategy, I show that managers must consider not only the type of threat acting on a metapopulation, but also how a threat might also respond to increased colonisation of a focal species. In some instances, increasing the colonisation rate can be detrimental to metapopulation persistence because of increased exposure to threats occupying the same habitat. The fifth chapter examines which patches of suitable habitat should be managed to contain the spread of one of the worst invasive species in Australia, the cane toad (Rhinella marina). A previously published…

▼ Delineating the distribution of a threatened species is critical for identifying threats and guiding conservation management. The process is challenging, however, especially when a species is rapidly declining, and so changing its distribution. In this context, species distribution modelling (SDM) often lacks the precision needed to inform fine-scale management decisions, but on-ground surveys to test species’ distributions are time and resource intensive. The dilemma can be mitigated to some extent by careful examination of historical data, and optimal monitoring. The New Holland Mouse (NHM; Pseudomys novaehollandiae) is one of many Australian rodent species to have undergone drastic distributional declines since European invasion. Initially recorded in Victoria in 1970, by 2015 NHMs were thought to occur in only 3 of 12 historically occupied regions. I tested this decline with statistical rigour, using extensive Elliott and camera trapping surveys at >500 sites across Victoria. Combining my survey data with 48 years of others’ efforts, I evaluated the utility of standard Elliott trapping surveys and the efficacy of camera trapping for NHMs. I tested whether NHMs were where we would expect based on state-government threatened fauna SDMs, and whether the species’ purported early-successional fire association explained occurrence or abundance. I confirmed the species’ persistence in 5 of 12 historical regions – including regions where NHMs had not been detected in 5-21 years – and expanded the species’ known distribution in two regions. However, these finds can be attributed to a paucity of prior survey effort and were partnered with greater declines elsewhere. Elliott trapping surveys were often inadequate to provide statistical confidence in the species’ absence; camera trap surveys provide a viable alternative for distribution assessments. Standard state-government SDMs provided limited guidance as to the true distribution of NHMs and SDMs for declining species should be interpreted with caution. Time-since-fire did not explain the species’ occurrence and poorly explains abundance, though in certain locations inappropriate fire regimes are a threatening process. Predator control, habitat management, and careful reintroductions are key priorities for conservation of NHMs in Victoria.

▼ The conservation of threatened species requires an understanding of their ecology to identify the factors that are contributing to their decline and to assess their extinction risk. The objective of this thesis was to examine the ecology of Astelia australiana, a threatened herb endemic to Victoria, Australia to inform its conservation management. To achieve this objective, I examined how the distribution and abundance of A. australiana has changed over its entire known range in the 20- year period since its demographic monitoring program began. I also examined its habitat niche and regeneration ecology and response to potential threats including drought, wildfire, disease and low light availability. I then used this new understanding to develop a population viability model to explore the viability of A. australiana to current conditions, threats and limitations. The key findings of my research include a better understanding of the regeneration ecology of A. australiana including that it involves both sexual and asexual reproduction which occur at the same time. This reproduction occurs once in an individual’s lifetime and results in the production of flowers and fruit and three clones. Previously A. australiana had been variously described as dioecious and gynodioecious; however, it is trioecious, having male, female and hermaphrodite flowers on different plants and male and hermaphrodite flowers on the same plants. Various native bird and mammal species are involved in the regeneration ecology of A. australiana as pollinators and dispersers of fruit. Reproduction of A. australiana requires a minimum amount of available light from canopy gaps in the rainforest understorey to occur. A. australiana has declined in abundance by 57% over the 20-year period. Herbivory, and disease have contributed to mortality of A. australiana over this period but do not appear to be the only factors contributing to the observed decline. Although, A. australiana was found to be highly sensitive to drought, multiple lines of evidence including: the pattern of decline and recruitment of A. australiana; comparison of the physiological response of A. australiana to drought in an experimental trial with physiology of individuals in the rainforest; examination of the microclimate of the sites; and assessment of the growth response using dendrochronological techniques, of the dominant tree in the cool temperate rainforest, Nothofagus cunninghamii (Myrtle Beech) to drought periods, all indicate that drought is not driving the observed decline as had been previously concluded by others. Wildfire also resulted in a loss of individuals in one site that was burnt during the study period however, decline from this site was not included in the 57% change in abundance total. Changes in forest structure due to growth in the canopy reduce the light availability in the understory which limits A. australiana recruitment and increases mortality and thus contributes to the species decline. Population viability analysis of A. australiana, predicted that…
