Description
Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species. Recent BioScience author Steven Mattocks of the University of Massachusetts, in Amherst, joins us on this episode of BioScience Talks to discuss the effects of lost habitat and river connectivity for these crucial fish. In particular, he explains that because of a dearth of information on pre-1950 conditions, past estimates of lost biomass may drastically underestimate the ecological harm of damming.

Episode #9: Plague-Afflicted Prairie Dogs and Modeling Animal-Borne Disease: Animal-borne diseases have ruled the news cycle recently—from Zika and Ebola to SARS and MERS. However, little is known about the spread of these diseases in their animal hosts. More perplexing, the mechanisms that lead to human outbreaks remain elusive. by BioScience Talks
