Climate Change Impacts on BiodiversityWe develop and apply methods that link climate change models, ecological niche (species distribution or habitat suitability) models, and demographic models to predict the extinction risk of species under global climate change.
The development of this coupled niche-population modeling approach was based on our previous work (2003-2005) on metapopulation models with dynamic spatial structure, which were applied to simulate the effects of landscape changes resulting from timber harvest and fires. The first applications of this modeling approach to climate change were developed in a series of workshops in 2007-2009, in Silwood Park, UK; Madrid, Spain; and Adelaide, Australia. One of the goals of these projects is to contribute to the development of Red List Guidelines for identifying species threatened by climate change.
Research papers that proposed, developed, and applied the coupled niche-demographic modeling approach (as well as other methods) are listed and described below.
