The geography of climate change: implications for conservation biogeography

Abstract Aim Climate change poses significant threats to biodiversity, including impacts on species distributions, abundance and ecological interactions. At a landscape scale, these impacts, and biotic responses such as adaptation and migration, will be mediated by spatial heterogeneity in climate and climate change. We examine several aspects of the geography of climate change and their significance for biodiversity conservation. Location California and Nevada, USA. Methods Using current climate surfaces (PRISM) and two scenarios of future climate (A1b, 2070–2099, warmer‐drier and warmer‐wetter), we mapped disappearing, declining, expanding and novel climates, and the velocity and direction of climate change…
