Location matters: For invasive aquatic species, it’s better to start upstream

These green crabs have been doing a number on native shellfish. They eat a lot of clams. And they're a very cosmopolitan species—they've now spread all over, to places as far afield as the West Coast of the U.S. and South Africa. [...more]

Ecologists at the Smithsonian Environmental Research Center measure the growth rate of sedge grass in a brackish Chesapeake Bay marsh. Fed a diet rich in CO2 and nitrogen, conditions that mimic the rise of atmospheric CO2  and pollution from farming and wastewater, the sedge has been grown and monitored in test chambers by Smithsonian scientist [...] [...more]

This fossil represents a new genus and species of extinct aneuretopsychid, Jeholopsyche liaoningensis, recently described in a paper in the journal ZooKeys by Conrad Labandeira of the Smithsonian’s National Museum of Natural History, and Dong Ren and ChungKun Shih of the College of Life Sciences, Capital Normal University, Beijing. The aneuretopsychidae are a family of long-proboscid insects that lived in Asia from the Late Jurassic to Early Cretaceous. The paper documents the first formal record of fossil Aneuretopsychidae in China. The new fossils reveal previously unknown and detailed structure of the mouthparts, antennae, head, thorax, legs and abdomen of this distinctive insect lineage.
