Glaciers drove kiwi diversity – Expert reaction

Sarah-Jane O'Connor posted in on August 30th, 2016.

A new study suggests kiwi are more diverse than previously thought, thanks to ice age glaciations driving evolution into multiple lineages. Researchers based in Canada, in collaboration with Department of Conservation scientists, examined a database of kiwi DNA across the geographic range of the five known kiwi species.

An excerpt: (read in full here) “Those winds also brought hot air and warm seawater south from the equator, which caused the beginning of warming in […]

Newsletter Digest: Southern Ocean carbon sink and NZ’s synthetic bio sitrep

Will the Southern Ocean carbon sink hold? Ice core records show there was a sharp rise in carbon dioxide in the atmosphere – a nearly 50% increase – at the end of the last ice age. Scientists have long puzzled over the origin of all the extra CO2 that appeared as the great ice sheets […]

Will the Southern Ocean’s carbon sink hold its breath?
