redOrbit Staff & Wire Reports - Your Universe Online The pre-Ice Age marine mammals of the North Pacific were a diverse and fascinating lot, according to an analysis of hundreds of fossil bones and teeth excavated from the San Francisco Bay Area's Purisima Formation. Robert Boessenecker, a geology PhD student at New Zealand's University of Otago, put together a record of 21 marine mammal species that were fossilized 5 to 2.5 million years ago, including dwarf baleen whales, odd...

Five Distinct Humpback Whale Populations Identified In North Pacific Ocean
2013-12-04 19:40:46

Lee Rannals for redOrbit.com – Your Universe Online A new genetic study shows there are five distinct humpback whale populations in the North Pacific Ocean. There is currently a proposal to try and designate North Pacific humpbacks as a single distinct population segment, which could ultimately threaten the species’ endangered status. Humpback whales are listed as endangered in the US under the Endangered Species Act, but the species has recently been downlisted by the...

Killer Whales Use Stealth Approach When Hunting Prey

[ Watch the Video: Stealthy Tactics Used By Orca To Catch Their Prey ] redOrbit Staff & Wire Reports - Your Universe Online Newly discovered evidence that killer whales can hunt marine mammals during the nighttime has led scientists to suggest that the creatures can use their hearing to help locate prey, according to research presented at the 166th Meeting of the Acoustical Society of America (ASA). For example, the study authors said that the whales eavesdrop on male harbor...

New Method Measuring Marine Noise
2013-12-03 12:02:16

Brett Smith for redOrbit.com - Your Universe Online Previous research has found that underwater noise can be stressful or even harmful to sea creatures, and a team of UK scientists has devised a novel method for monitoring artificial noise in Scotland’s Moray Firth inlet, according to a newly published study in the journal Marine Pollution Bulletin. Study author Nathan Merchant, a postdoctoral researcher at the University of Syracuse, said human activities related to Scotland’s...

Mapping Human Impacts On Top Marine Predators
2013-10-29 08:00:43

April Flowers for redOrbit.com - Your Universe Online One of the richest ecosystems in the world, the California Current System, is driven by nutrient input from coastal upwelling and supports a great diversity of marine life. It is also heavily impacted by human activities, much like other coastal regions. Researchers from the University of California, Santa Cruz (UCSC), reveal areas along the west coast where human impacts on marine predators such as whales, seals, seabirds and sea...

Increased Abundance Of Humpback Whales In Critical Feeding Habitat

Public Library of Science Humpback whale populations are on the rise in the coastal fjords of British Columbia, doubling in size from 2004 to 2011, according to results published September 18 in the open access journal PLOS ONE by Erin Ashe from the Sea Mammal Research Unit at the University of St. Andrews and colleagues from other institutions. Researchers estimated abundance of Pacific humpback whales (Megaptera novaeangliae) using photo-identification surveillance of identifiable...

Whale’s Slow Death Caused By Fishing Gear
2013-05-22 11:06:50

Brett Smith for redOrbit.com — Your Universe Online While bans against whale hunting have greatly reduced the direct threat fishermen pose to the marine mammals, a new study in the journal Marine Mammal Science points to a deadly indirect threat — potential entanglement in fishing lines. Using a patented monitoring device, marine biologists from the Woods Hole Oceanographic Institution (WHOI) in Massachusetts were able to observe how an entangled whale called Eg 3911...

1972 Law Has Done Well To Protect Sea Mammals In US Waters
2013-04-12 13:41:54

Brett Smith for redOrbit.com - Your Universe Online In October 1972, Congress passed the Marine Mammal Protection Act (MMPA), a landmark law that enacted a moratorium on the import, export, and financial transaction of any marine mammal or their parts within the United States. To mark the 40th anniversary of its passage, a team of American biologists has published an analysis of the law´s effectiveness in the latest edition of the Annals of the New York Academy of Sciences (NYAS)....

Marine Mammals Need To Eat Right To Survive
2012-11-23 06:25:17

April Flowers for redOrbit.com - Your Universe Online High-energy prey make for high-energy predators in the marine world. Survival, for those predators, depends on sustaining the right kind of high-energy diet, so not just any prey will do. A new study from the University of British Columbia (UBC) and the University of La Rochelle (ULR), published online in the journal PLOS ONE, is the first to show that the survival of whales and dolphins depends on the quality of their diets. These...
