What role do emotions play? Why do some ex-smokers […]
Scientists and fishermen are working together to gain new insight into seasonal movements of valuable Pacific cod. Cutting edge technology and fishermen’s expertise are helping scientists track Aleutian Islands Pacific cod for the first time. Last winter scientists and fishermen partnered to launch a pilot study to develop methods for tagging cod on working commercial fishing […]
University of Alaska Fairbanks scientists are developing a new method to predict ecosystem change in Interior Alaska, and their techniques could prove useful elsewhere in the world. The study uses real-time water data, rather than simulations, to predict ecosystem “tipping points.” “We’re pretty good, as ecosystem ecologists, at using stream chemistry to tell us […]
