New findings suggest that abnormal ocean currents cause the occasional appearance of pelagic red crabs outside their native range.
New understanding of relationship between stream flows and salmon survival provides a critical tool for balancing water needs in the highly managed Sacramento River.
A threshold defined as the “historic mean” flow of 10,712 cubic feet per second (cfs) provides an especially important target for resource managers, said Cyril Michel, associate project scientist in the Fisheries Collaborative Program at UC Santa Cruz.
