Mechanisms underpinning the impact of climate change on natural populations

There is an urgent need to identify the key mechanisms underpinning climate change impacts on biodiversity in order to inform climate change adaptation. This project will review the scientific literature to quantify the evidence for different potential climate change impact mechanisms and appraise their relative importance. Meta-analyses will be conducted to consider how their relative importance varies between taxa, habitats and regions. Results will be reported in a scientific paper and a policy-maker summary.

This project was funded by the CCI Collaborative Fund.

 

Project Aims

The project aims to conduct a comprehensive literature review and meta-analysis of the scientific and grey literature to quantify the evidence for different potential climate change impact mechanisms and appraise their relative importance, in order to address the following questions.

  1. What are the mechanisms underpinning climate change impacts on natural populations that have the most evidence to support them? Are the mechanisms that are most frequently investigated the same as those with the most evidence?
  2. Does the importance of different mechanisms vary between taxa, and to what extent can such variation be accounted for by various ecological traits?
  3. Does the importance of different mechanisms vary geographically and between habitats?

This information will be used to develop a matrix of species groups and environments in order to highlight which impacts are likely to be most important in particular circumstances. Meta-analyses will be conducted to consider how their relative importance varies between taxa, habitats and regions. Results will be reported in a paper aimed at a high-impact journal and a policy-maker summary; they are intended to serve the IPCC’s upcoming 5th Assessment Report and to inform conservation adaptation management.

 

Key Activities

  • Regular meetings over the course of the project to discuss how to approach the systematic review, and which elements of it will be led by each CCI partner.

Mechanisms underpinning climatic impacts on natural populations: altered species interactions are more important than direct effects

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…
