Sense in Sensitivity: Assessing Species Vulnerability to Climate Change
… the impact of future climate change upon species vulnerability. Reports of shifts in species distributions are already numerous, but the pattern of change is not fully understood. This thesis looks to predict which species are likely to be most at risk under climate change and why? This …

An approach to the requirements for active management of different elements in New Zealand avifauna: Presented in partial fulfilment of the requirements for the Degree of Masters of Science in the University of Canterbury
… New Zealand avifauna can only proceed if those species which are vulnerable to extinction are known. An approach for establishing criteria to assess species vulnerability to extinction that uses population biology, genetics, and modelling is outlined. These criteria also provide a classification …

Climate Change and Potential Economic Impacts in Ireland: The Case for Adaptation
… on sustainability science the terms resilience, vulnerability and adaptive capacity are also discussed, defined and engaged with. Key results, associated with both potential climate impact and adaptation costs, are presented from global and regional integrated assessment models and in turn …

Potential Interaction Analysis of Offshore Wind Energy Areas and Breeding Avian Species on the US Mid-Atlantic Coast
… We combined colony size and location for each species along the mid-Atlantic coast with buffers around the colonies that correlate with the species’ foraging range. We integrated population size, vulnerability to offshore wind, and foraging areas to create a multi-species vulnerability model …

Predicting Mobile Species Response to Landscape Structure: The Roles of Spatiotemporal Pattern and Individual Dispersal
… impact resident populations of animal species, is a critical question for the conservation management of multiple-use reserves harboring rare and endangered species. Here I examine this question with a general, spatially-explicit, stochastic, individual-based simulation of a continuous …

Computer vision enabled approaches to predicting responses to fluctuating temperatures in aquatic embryos
… sensitive life stage, and thus can drive a species’ vulnerability to climate change. Our current understanding of the effects of fluctuating temperatures (FTs) is predominately based upon comparisons of responses to constant temperatures (CTs). Relating CT responses to those of FTs is …

Can sociality buffer the impacts of climate change on a cooperatively-breeding bird, the southern pied babbler Turdoides bicolor?
… populations everywhere and understanding how species respond to current environmental variability is important for predicting vulnerability to climate change over longer timescales. Species living in characteristically harsh and unpredictable arid and semi-arid ecosystems are useful models for …

Using population ecology to inform the conservation of Nevada's rare plants
… size is a necessary first step in assessing species vulnerability, and to the subsequent examination of population viability, prediction of extinction risks, and evaluation of conservation objectives. Population censuses and demographic monitoring are important tools in illuminating overall …

Insects in mountainous landscapes: Implications of landscape context and climate change
… The effects of landscape context on individual species are often complex and species-specific. Furthermore, interactions with higher trophic levels, such as parasitoids, and the spatio-temporal scaledependencies of habitat parameters further complicate the investigation of species habitat …

Environmental Change Impacts on Marine Calcifiers: Spatial and Temporal Biomineralisation Patterns in Mytilid Bivalves
… factors mediating spatial and temporal species’ responses to habitat alterations underpins our ability to forecast impacts on marine ecosystems under any range of scenarios. This is especially important for calcifying species, many of which have both a high climate sensitivity and …

A climate change vulnerability assessment of 58 Richtersveld plant species
… with regards to plants and climate change vulnerability. In this study I aimed to find which Richtersveld species are the most vulnerable to climate change while trialling a relatively novel approach in this context. I used a trait-based assessment with correlative species distribution …

Investigating the movement and foraging ecology of reef manta rays (Mobula alfredi) in the Chagos Archipelago
… elasmobranchs of the family Mobulidae. The species is dispersed throughout the Indian and West Pacific Oceans in small, isolated populations that tend to have a limited home range. Individuals within a population regularly visit specific locations to routinely engage in activities such as …

Revisiting Aloe dichotoma’s suitability as an indictor of climate change in southern Africa
… in the southern and central distribution of the species within the first half of the 20th century. This, as well as possible previous assumptive and interpretive problems prompted a reassessment of the evidence for A. dichotoma’s promotion as a climate change indicator species. In the current …
