The food web in Great Plains streams could be unraveling, according to a Kansas State University ecologist.

Keith Gido, professor of biology, and Josh Perkin, a Kansas State University alumnus, recently published "Groundwater declines are linked to changes in Great Plains stream fish assemblages" in the Proceedings of the National Academy of Sciences. The research maps the loss of stream habitat for many small fish in the Great Plains region and attributes it to declining groundwater sources.

Scientists at the University of York have shown that using historical wildlife data provides a more accurate measure of how vulnerable certain species might be to extinction from climate change.

Some of the methods used to predict at risk species are trend-based – an indicator of what happens gradually over time – while others are trait based, which uses signs of climate change in the current environment.

NASA’s Aqua satellite is keeping track of Typhoon Noru as it continues its slow trek through the Northwestern Pacific Ocean.

On August 2, 2017 at 12:05 a.m. EDT (0405 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Aqua satellite captured a visible image of Typhoon Noru. The MODIS image shows a symmetric band of thunderstorms completely surrounding a well-defined eye feature.

The largest remaining ice shelf on the Antarctic Peninsula lost 10% of its area when an iceberg four times the size of London broke free earlier this month.

Since the 12 July 2017 breakaway Dr Anna Hogg, from the University of Leeds, and Dr Hilmar Gudmundsson, from the British Antarctic Survey (BAS), have continued to track the iceberg – known as A68 – using the European Space Agency (ESA) and European Commission’s Copernicus Sentinel-1 satellite.

A team led by geoscientists from Arizona State University and Michigan State University has used computer modeling to explain how pockets of mushy rock accumulate at the boundary between Earth's core and mantle.
