Predictive models that can forecast biodiversity decline under anthropogenic climate change used to be too simplistic, as these ignored crucial biological mechanisms such as demography, dispersal, evolution, and species interactions (for instance species competition and ecosystem dependence). Fortunately these climate-biodiversity … Continue reading
Climate change leads to species extinctions and exponentially so: the loss of biodiversity is set to accelerate under continuation of global average temperature rise.
Yes, we found yet another publication that is critical of one-dimensional biodiversity loss projections of climate change – and again it is a component of interspecies interaction that may be underestimated. We’ve previously looked at species competition and at evolutionary … Continue reading
As species migrate in response to climate change and do so at different rates and dispersal directions, extra ecosystem disturbances might arise, leading to temporary local biodiversity increases – fuelling a net (global) downward trend.
Quickly migrating species can keep track of climate change by migrating along the optimum of their climate zone habitat. Paradoxically these species increase the pressure on slower dispersers, increasing their extinction risk. Overall, adding such complex interspecies interaction to models … Continue reading
