Freeze-dried mats of microbes awaken in Antarctic streambed

Geoscientists follow arsenic from chicken feed to streambeds

...t low concentrations of arsenic are transported to streambeds instead of being retained by the aquifers, Schreiber said. "We think that the arsenic is adsorbed onto nanoscale particles that pass though our filters and through the soil column," said Schreiber. "This suggests that particle transport is an importa...

Habitat microstructure drives salamander metamorphosis

...etamorphoses into a more terrestrial adult form in streambeds composed of fine, tightly packed gravel but retains its juvenile, or paedomorphic, form in streambeds made of large, loosely packed particles. This study highlights how a simple difference in habitat mi...
