Résumé documentaire — langue originale

Abstract Climate change is a major factor contributing to biodiversity loss globally and in Australia. Addressing this conservation challenge requires information about present and future species distributions. To improve assessment of future species distributions, we have developed 19 bioclimatic indices calculated from dynamically and statistically downscaled Coupled Model Intercomparison Project 6 global climate models (GCMs) over Australia at a 5 km resolution through 1975–2099 for three emissions scenarios. These data are available on EcoCommons, an ecological modelling web platform used by conservation researchers and practitioners. Here, we demonstrate the use of this dataset in species distribution modelling using a case study of the southern and central populations of the greater glider ( Petauroides volans , referred to as P.volans hereafter). By the end of the century, projections for bioclimatic indices which measure temperature have increased by 2.9 °C–4.0 °C for the high emission scenario (SSP3-70; Shared Socioeconomic Pathway 3 with 7.0 W m −2 radiative forcing). Indices related to temperature range tend to decrease in northern Australia and increase in southern Australia, while isothermality increases along the northern coast of Australia. Precipitation based indices show a high amount of variability, due to the model uncertainty in precipitation projections for Australia, though there is a tendency for increases in precipitation during the warm and wet seasons, and decreases during the cooler and drier seasons. Our case study of the greater glider shows that by the end of the century under the high emission scenario (SSP3-7.0), its potential climatic range will be reduced by about 30%–50% across Australia, and in Queensland by over 90%. This study illustrates the utility of the 5 km statistically downscaled data and the use of the EcoCommons platform for analysing projected climate change impacts on species distributions in Australia.
