The recent description of the Tremadocian halkieriid-like stem aculiferan, Calvapilosa kroegeri, could shed new light on some enigmatic Ordovician fossils known only by their disarticulated plates. Specifically, Conchopeltis alternata could be interpreted as a...

The polar bear (Ursus maritimus) was the first species to be classified as threatened with extinction based on predictions of future conditions rather than current status. These predictions were made using expert-opinion forecasts of population declines linked...

Our ability to prevent extinction in declining populations often depends on effective management of habitats that are disturbed through wildfire, logging, agriculture, or development. In these disturbed landscapes, the juxtaposition of multiple habitat types can...
