Artificial intelligence is emerging as a powerful new tool for whale identification. New software can be adapted and used to identify any animal with a dorsal fin on its back.
Beavers are typically associated with freshwater environments, but scientists have learned that they also survive and thrive in the shoreline marshes of the Salish Sea. New research is shedding light on the vital connection between tidal beavers and salmon.
Pink salmon now comprise nearly 80 percent of all adult salmon in the North Pacific. This record abundance is coming at a cost to other salmon species such as threatened Chinook, which compete with pinks for spawning territory. A new study shows that the ecological toll may extend all the way to endangered southern resident killer whales.
Just last year, scientists published the first direct evidence that noise interferes with orca feeding behavior. Officials hope a new law establishing a larger buffer zone between boats and endangered southern resident orcas will mean quieter seas and healthier whales.
The appropriately named common dolphin is probably the most abundant cetacean on the planet. Common dolphins occur in most of the world’s tropical and temperate waters. Historically, they have not been common in inshore waters in Puget Sound and the Salish Sea but they are becoming more frequent as water temperatures warm.
A formal proposal to designate resident and Bigg’s killer whales as separate species has been rejected by a committee widely recognized as the authority in naming new marine mammal species.
