Anthropogenic climate change and land use change in the form of agricultural expansion (‘habitat conversion’ – a sweet description for deforestation) act as synergistic drivers of biodiversity loss – in a Costa Rican environmental experiment – literally drying out the … Continue reading
Again, the use of a geographical approach (and here defining biodiversity as ‘biotic intactness’) shows the Holocene-Anthropocene Mass Extinction is progressing faster then generally thought – and ‘biodiversity safe limits’, however arbitrarily defined, have already been passed on most of … Continue reading
Whether you focus on mammals, birds, reptiles or amphibians – land vertebrates are in rapid decline everywhere around us, illustrating a general decline of Life on Earth – and a prelude to the Holocene-Anthropocene Mass Extinction, that is being underestimated … Continue reading
If you live inside a heap of compost in someone’s backyard, your life may already feel quite miserable. But if you’re really tiny, at least you’re probably thinking your chances of surviving climate chance are –comparatively– okay. Well, our dear … Continue reading
If what goes for worms goes for the wider world, there is an important lesson to be learned: in order to prevent extinctions, we need to improve ecosystem health – before climate change kicks in. That is because ecosystems with … Continue reading
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
