Alterations in species’ distribution and abundance as a consequence of changes in climate are well-known, but the processes that underpin these changes are not well understood. A literature review and meta-analysis undertaken by a collaboration of researchers from CCI partners, led by James Pearce-Higgins of the British Trust for Ornithology, have now shed light on these underpinning processes. The researchers found that indirect, biotic mechanisms associated with changes in species interactions appear to have a more significant bearing on the relationship between populations and climate than direct, abiotic mechanisms of climate, such as changes in temperature.
This paper was produced as one of the outputs from a CCI Collaborative Fund project.
