GeoSciences Column: Forests in flux – log-jams in the Amazon

Collapsing dams are a staple of disaster films, but the form that these take in natural systems is also surprisingly varied. Streams and rivers can be blocked by a range of rapid and gradual inputs. One of the lesser-known causes of stream blockage is through the accumulation of large woody debris – tree trunks and large branches – to form a log jam. The impact of these jams on river geomorphology ...[Read More]

In this post, originally published in June 2017 on the blog of the Geological Society of America (GSA), Terri Cook, a science and travel writer and former winner of the EGU’s Science Journalism Fellowship, argues the importance of quality science communication as a means for scientists to make their research accessible to a broad audience. One way to achieve this is working with a science jo ...[Read More]

We often read about Earth’s mass extinction events and how they wiped out vast numbers of animal species, leaving survivors to evolve and repopulate the planet. But it’s rarer to hear about how plants managed these catastrophes. A new study published last month by a team at University College Dublin, Ireland, in the journal Nature Plants shows how plants with thicker, heavier leaves we ...[Read More]
