Researchers examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales from 2012 to 2018. They looked at 11 different animal species to test for 17 different substances. The study is the first to report on concentrations in blubber tissues of stranded cetaceans of atrazine, DEP, NPE and triclosan. It also is the first to report concentrations of toxicants in a white-beaked dolphin and in Gervais’ beaked whales.
New research by an international team of scientists reveals that endangered North Atlantic right whales are in much poorer body condition than their counterparts in the southern hemisphere.
Microbial communities inside whales may play an important role in the digestion of one of the ocean’s most abundant carbon-rich lipids, known as a wax ester.
The highly endangered North Atlantic right whale is rapidly altering its use of important habitat areas off the New England coast, signaling disruptive changes in the marine environment.
A new study finds the western South Atlantic humpback population has grown to 25,000 whales. Researchers believe this new estimate is now close to pre-whaling numbers.
