The synergistic impact of threats to biodiversity under global change (global warming, invasive species, habitat loss, etc.) is predicted based on theory and limited observation, but the magnitude of the interactions compared to additive effects is poorly quantified. In this study, a meta-analysis of 168 published papers from the last 20 years showed that habitat loss was positively related to maximum temperatures and negatively related to minimum temperatures and change in precipitation.
The logistic regression coefficients were relatively small for the climate change parameters, especially shift in mean temperature. Thus it was climate state, rather than climate change, that was more important for explaining habitat loss and fragmentation. This result may be due to lack of time for climate change to have a substantial impact. The other unsurprising result from this finding is that the tropics are losing habitat quickly and deserts less so. The overall conclusion is that areas at physiological limits for species are particularly susceptible to the synergy of global change drivers.
