The zoogeographic distribution of Dolly Varden (Salvelinus malma) and whitespotted charr (S. leucomaenis) overlap in Hokkaido Island, northern Japan, but they occur in sympatry in relatively short segments of streams that shift in elevation across the island.  Moreover, in these sympatric segments Dolly Varden shift their foraging behavior to focus on benthic invertebrates and avoid direct interference competition with whitespotted charr, and also display shifts in head and jaw morphology that enhance foraging on benthic prey.  In turn, this ability to shift to benthic feeding can alter benthic communities and the resulting emergence of adult aquatic insects that are important prey for riparian predators like bats, birds, and spiders.  Research conducted over the last three decades with Japanese scientists in Hokkaido has revealed the complex interplay among these factors that contribute to the mystery of charrs.

Kurt Fausch er heimsþekktur vísindamaður sem hefur helgað líf sitt rannsóknum og miðlun þekkingar um vistfræði vatnakerfa, með sérstakri áherslu á ár og fiskana í þeim, þ.m.t. laxfiska. Hann er baráttumaður fyrir skynsamlegri umgengni og nýtingu straumvatna og bendir á að árnar eru lífæð mannkyns sem ber að varðveita og umgangast af virðingu. Hann er m.a. höfundur bókarinnar For the Love of Rivers: A Scientist’s Journey, sem kom út 2015.

Kurt Fausch is a Professor Emeritus in the Department of Fish, Wildlife, and Conservation Biology at Colorado State University, where he taught for 35 years.  His research collaborations in stream ecology and fish conservation have taken him throughout Colorado and the western U.S., and worldwide, including to Hokkaido in northern Japan.  His experiences were chronicled in the documentary film RiverWebs, and the book For the Love of Rivers: A Scientist’s Journey, which won the Sigurd Olson Nature Writing Award.   He received lifetime achievement awards from the American Fisheries Society, the World Council of Fisheries Societies, and Fly Fishers International, and served as the acting director of the Graduate Degree Program in Ecology at Colorado State University.
