Increased Ocean Acidification Rate Puts Polar Ecosystems at Risk
An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, with effects especially pronounced in…

Climate change pushing tropical trees upslope ‘exactly as predicted’
Tropical tree communities are moving up mountainsides to cooler habitats as temperatures rise, a new study in Global Change Biology has found. By examining the tree species present in ten one-hectare plots at various intervals over a decade, researchers found that the proportion of lowland species increased in the plots at higher elevations.

Eggshell of extinct giant bird provides ancient DNA
In a world first an international team of researchers have successfully extracted ancient DNA from the eggshells of various species of extinct birds. The research, published in scientific journal Proceedings of the Royal Society B, shows that fossil eggshell is a previously unrecognised source of ancient DNA and can provide exceptional long-term preservation of DNA…
