Methods for measuring change when marine tidal turbines are implemented

A new paper in Ecological Indicators by Hannah Linder and SAFS professor John Horne examines a wide range of statistical methods for detecting and forecasting change from monitoring studies. They found that different classes of models are needed to detect change, and to forecast the future effects of interventions such as building marine tidal turbines.

The most valuable salmon fishery in the world could become a mine

A front page investigative CNN article outlines how the Environmental Protection Agency reversed a decision to protect the most valuable salmon fishery in the world, giving the go-ahead for the Pebble Mine, one hour after the head met with the CEO of the Pebble Mine partnership. SAFS professor Thomas Quinn comments in the report: “This is the jewel in the crown of America’s fisheries resources – these salmon.

Fisheries can alter the timing of spawning and migration in fish

Fishing can substantially alter when fish migrate and when they breed, says a new review in Fish and Fisheries by SAFS student Michael Tillotson and faculty member Thomas Quinn. For example, fishing closures may increase fishing on late breeders, resulting in a greater proportion of early breeders in the population. Such changes can exacerbate the effects of climate-driven changes in the timing of migration and breeding.

New 3-D scanning campaign will reveal 20,000 animals in stunning detail

Science magazine reports that faculty members Luke Tournabene and Adam Summers have a new mission in life: CT scanning all the vertebrates in the world, with fish and frogs well on their way. All the scans will be made freely available for researchers to have access to unprecedented 3-D images of the skeletal structure of 80% of all vertebrates.

Rethinking the scientific career

Faculty member Julian Olden and others in ChronicleVitae urge scientists to see their careers as “an adventure on a long and winding path” that involves interacting with nature and making their science relevant. Instead of focusing on publishing small units of science, we should be embracing the spirit of discovery and striving for societal impact.

More than 10,000 seabirds die from harmful algal blooms, recorded by citizen scientists

Citizen scientists in a program run by Julia Parrish provided data about two mass die-offs of seabirds on the outer coast of Washington state, which is the largest mass death ever to be definitively ascribed to harmful algal blooms. The new report was authored by SAFS postdoc Timothy Jones, with other SAFS contributions from Julia Parrish, André Punt, and Jennifer Lang, as part of the Coastal Observation and Seabird Survey Team (COASST; a citizen science program at the University of Washington).
