Climate Change & Anthropocene Extinction 4: Earth’s biodiversity may include >1,000,000,000,000 species(!)

Yes. That’s ONE TRILLION. ‘Possibly’ – as recent research using statistical scaling rules shows Earth’s total biodiversity, expressed in numbers of species, lies somewhere between 100 billion and (possibly more than) ten times as much. Welcome to the world of … Continue reading

Climate Change & Holocene-Anthropocene Mass Extinction 2: Biodiversity graph shows Garden of Eden is Now

Yesterday we tried to place the Holocene-Anthropocene Mass Extinction in the context of Earth’s past mass extinctions. Listing the Holocene Extinction as the ‘Sixth Mass Extinction’ proves problematic for various reasons. Today we offer additional context: although a mass extinction … Continue reading

Effects of climate change on mountain plants is delayed

Percentage of unsuitable occupied ecological sites

Percentage of unsuitable sites among those predicted to be occupied.

A modeling study from the European Alps suggests that population declines to be observed during the upcoming decades will probably underestimate the long-term effects of recent climate warming on mountain plants. A European team of ecologists around Stefan Dullinger from the Department of Conservation Biology, Vegetation and Landscape Ecology of the University of Vienna presents a new modeling tool to predict migration of mountain plants which explicitly takes population dynamic processes into account. Their results are published in “Nature Climate Change“.

Metastudy shows current climate change makes flora and fauna shrink

The paleoclimatic record shows it has happened before – and now two well-read researchers illustrate it is already happening again: species across life’s kingdoms are decreasing in size, due to warming, droughts and acidification. It’s a sign ecology is feeling … Continue reading
