Scientists have confirmed that East Antarctica’s interior is warming faster than its coastal areas and identified the cause. A 30-year study, published in Nature Communications and led by Nagoya University’s Naoyuki Kurita, has traced this warming to increased warm air flow triggered by temperature changes in the Southern Indian Ocean. Previously considered an observation “blind…

Among the tiniest living things in the ocean are a group of single celled microbes called Prochlorococcus. They are cyanobacteria, also known as blue-green algae, and they supply nutrients for animals all the way up the food chain. Over 75% of surface waters teem with Prochlorococcus, but as ocean temperatures rise, researchers fear that the…

The spread of species beyond their native habitat is a human-made environmental change on a global scale. Among vascular plants, over 16,000 species have now permanently settled in foreign countries. The majority of these “naturalizations” has taken place since the 1950s and predominantly in regions with considerable human influence. Naturalized alien plants, also known as…

Flathead catfish, opportunistic predators native to the Mississippi River basin, have the potential to decimate native and recreational fisheries, disrupting ecosystems in rivers where they become established after their introduction or invasion from a nearby river drainage. That concern led a team of researchers from Penn State, the U.S. Geological Survey (USGS), and the Pennsylvania…
