Evolutionary 'arms race' -- how dolphins and whales fight disease threats - A groundbreaking study reveals how dolphins, whales and other cetaceans compete for survival in an evolutionary 'arms race' with changing pathogenic threats like mercury and brevotoxin (e.g. Red Tide). Researchers show that cetaceans use several strategies for success in this race. They have developed tools to help wildlife managers and health professionals assess disease risk from the perspective of how individual animals are engineered to recognize the molecules of microorganisms in the environment and launch an immune response.
Polar bears gorged on whales to survive past warm periods; won't suffice as climate warms - A new study found that while dead whales are valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers.
PCB pollution threatens to wipe out killer whales - A new study shows that more than 40 years after the first initiatives were taken to ban the use of PCBs, the chemical pollutants remain a deadly threat to animals at the top of the food chain
Aerial survey reveals great diversity and abundance in NE Canyons Marine National Monument - Airborne marine biologists were amazed by the sheer abundance and diversity of large marine wildlife in their recent aerial survey of the Northeast Canyons and Seamounts Marine National Monument, the only marine national monument on the East Coast, about 150 southeast of Cape Cod.
Endocrine disruptors found in bottlenose dolphins - Evidence of exposure to phthalates, chemical compounds used in hundreds of consumer products, has been found in resident bottlenose dolphins in Sarasota Bay, Florida. Some phthalates have been linked to reproductive problems in humans.
