Why is Earth so biologically diverse? Mountains hold the answer Posted: 12 Sep 2019 11:04 AM PDT Life on Earth is amazingly diverse, and exhibits striking geographical global patterns in biodiversity. A pair of companion papers reveal that mountain regions -- especially those in the tropics -- are hotspots of extraordinary and baffling richness. Although mountain regions cover only 25% of Earth's land area, they are home to more than 85% of the world's species of amphibians, birds, and mammals, and many of these are found only in mountains. |

Sulphur emissions from marine algae dropped during glacial periods Posted: 12 Sep 2019 07:09 AM PDT Contrary to conventional wisdom, sulphur production by tiny marine algae decreased during glacial periods, and is more closely linked to climate than previously thought, according to latest research. A clearer understanding of the link between the climate and marine phytoplankton can help scientists incorporate these impacts in future climate models. |
