Adaptive capacity of alpine fauna in Australia

Climate change is leading to rapid and unprecedented changes to Australia's alpine ecosystems. The impacts of these changes at a species level are not fully understood, making it challenging to holistically assess the impacts of a changing climate in these ecosystems. To address this gap, we combine a literature review with expert opinion to conduct individual adaptive capacity analyses for 29 species of Australia's alpine animals. We conduct these analyses using a published framework which encompasses key themes, such as life history, capacity for movement, genetic variation, and distribution. Our results highlight diversity in the adaptive capacity of Australia's alpine animals and suggest that climate change will impact even closely related species in surprisingly disparate ways. Our study also provides an example of how to overcome perceived data deficiency and support conservation practitioners with what is known. We have created an important resource for land managers in Australia's Alps that systematically integrates diverse data to provide insight into the mechanisms behind the vulnerability of some of Australia's most threatened species to climate change. The evidence this study collates should be considered in conservation planning to ensure species-level natural history information is included in decisions about management actions to mitigate climate change impacts.

Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change

Assessing the vulnerability of species to climate change serves as the basis for climate‐adaptation planning and climate‐smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive capacity (AC). AC is a species’ ability to cope with or adjust to changing climatic conditions, and is the least understood and most inconsistently applied of these three factors. We propose an attribute‐based framework for evaluating the AC of species, identifying two general classes of adaptive responses: “persist in place” and “shift in space”. Persist‐in‐place attributes enable species to survive in situ, whereas the shift‐in‐space response emphasizes attributes that facilitate tracking of suitable bioclimatic conditions. We provide guidance for assessing AC attributes and demonstrate the framework's application for species with disparate life histories. Results illustrate the broad utility of this generalized framework for informing adaptation planning and guiding species conservation in a rapidly changing climate.
