Faculty Eve Robinson and Nicholas Som Biological Sciences

Eve Robinson (Department of Biological Sciences) and Nicholas Som (Department of Fisheries Biology; USFWS) co-authored an article in the North American Journal of Fisheries Management, titled “Prevalence of infection in hatchery-origin Chinook Salmon correlates with abundance of Ceratonova shasta spores: implications for management and disease risk”.  Their research was motivated by questions the State raised about potential linkages between hatchery fish and disease risk, and results from this work were published earlier this year in time to be used by decision-makers in timing the release of hatchery smolts in the Klamath River.

Faculty Dr. Laura Levy Geology

Dr. Laura Levy, in collaboration with 11 co-authors, published “Multi-phased deglaciation of south and southeast Greenland controlled by climate and topographic setting” in the journal Quaternary Science Reviews. This comprehensive study tracked the timing of retreat of the Greenland Ice Sheet since the last ice age in an area of Greenland that is especially sensitive to climate change.

Faculty Steven Railsback, Bret Harvey Mathematics

Steven Railsback (adjunct faculty, Mathematics) and Bret Harvey (adjunct, Fisheries Biology) just published the book “Modeling Populations of Adaptive Individuals”, volume 63 in the prestigious Princeton Monographs in Population Biology series. The book presents a new kind of theory for adaptive behavior of individual organisms (e.g., when and where to forage, considering both growth and predation risk) that works in complex individual-based population models. The book builds on Humboldt’s long tradition in individual-based ecological modeling.
