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 →
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 →
“Over last 30 years 50% of coral has disappeared” “Based on current trends, within the next 30 years annual bleaching will kill most of the world’s coral” Earlier this month a new climate impact documentary was released, called Chasing Coral. … Continue reading →
Climate change is a direct disturbing factor to ecosystem health. It also leads to geographical biome shifts and therefore forced species migrations. Invasive species and food chain disturbances can lead to plagues, creating further ecosystem damage. All these factors work … Continue reading →
In 2016 two influential new publications raised the possibility of a rapid acceleration of sea level rise in the 21st century – to ±2 metres (DeConto & Pollard) or more (2-5m, Hansen et al). In this background article we take … Continue reading →
