Northern and southern resident orcas hunt differently, which may help explain the decline of southern orcas
In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.
The New York – New Jersey Harbor Estuary is a Dining Hotspot During Summer and Autumn Months for Bottlenose Dolphins
They click. They whistle. They love seafood. They are New York City’s nearshore bottlenose dolphins (Tursiops truncatus) that return to feed in local waters from spring to fall each year, and a team of scientists led by the Wildlife Conservation Society (WCS) is tracking them.
Offshore Wind Farms Could Disturb Marine Mammal Behavior #ASA182
When an offshore wind farm pops up, there is a period of noisy but well-studied and in most cases regulated construction. Once the turbines are operational, they provide a valuable source of renewable energy while emitting a constant lower level of sound.
Could Climate Change be Altering the Marine Food Web?
Research by scientists at Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) reveals that climate velocity is affecting where large marine mammals are distributed relative to their prey species, which could have important implications for marine food web dynamics.
Dolphin Calf Entangled in Fishing Line Only Lived Two Years Following Rescue
Researchers examined the outcome of an entangled bottlenose dolphin calf with monofilament fishing line wrapped tightly around its upper jaw. It was successfully disentangled and immediately released it back into its natural habitat. Surviving only two years, results showed long-term severe damage due to this entanglement including emaciation. There are about 1,000 bottlenose dolphins that live in the Indian River Lagoon, which also is a very popular location for recreational fishing.
