We can all imagine that climate change-driven migration of species will have global consequences. But what do the actual effects look like – and how do these feed back on ecology, climate and human societies?
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
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 reserves off Spain and Italy, we found the largest fish biomass in the Mediterranean. Unfortunately, around Turkey and Greece, the waters were bare” – Enric Sala, National Geographic Society.
If this is true best stack up on your supply of antiviral drugs, because there would be an above-average chance of experiencing another influenza pandemic during the approaching northern hemisphere spring or summer of 2012 (as indeed La Niña is … Continue reading
