The steady release of groundwater from the fractured rock that composes most mountainous regions sustains ecosystems and human activity during periods of drought. These groundwater systems are critically important for communities in mountainous areas such as Missoula, according to new research from the University of Montana. The new science was conducted by Matthew Swarr, a…
A new study by University of Victoria and Pacific Salmon Foundation scientists has uncovered what adult Chinook salmon in the Salish Sea are eating—and revealed diet can differ according to region.
The study, led by UVic PhD student Wesley Greentree and published recently in Fisheries Oceanography, analyzed the contents of salmon stomachs to assess salmon diet. Greentree found that year-round, herring are the most important food for adult Chinook salmon throughout the Salish Sea. Anchovy were often found in stomachs collected near Howe Sound and sand lance were important in Victoria and Sidney.
