Guadalupe fur seals (Arctocephalus townsendi) have established a large resting colony in the Gulf of California--bringing the total number of sites where this endangered species now occurs to just four. This new haul-out was discovered on El Farallón de San Ignacio Island, along the mainland coast of Mexico, according to researchers from Mexico and the University of British Columbia.
New research from marine biologists offers answers to a fundamental puzzle that had until now remained unsolved: why are some fish warm-blooded when most are not? It turns out that while (warm-blooded) fish able to regulate their own body temperatures can swim faster, they do not live in waters spanning a broader range of temperatures.
Ten estuaries on the West Coast of North America have been identified as priority locations for expanding the use of conservation aquaculture in a study led by the Native Olympia Oyster Collaborative and funded by the Science for Nature and People Partnership (SNAPP). SNAPP is a research collaboration supported by the National Center for Ecological Analysis & Synthesis (NCEAS) at UC Santa Barbara.
While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as 'blue-green algae' or cyanobacteria, that forms harmful floating blooms.
Pioneering research, led by a team from Trinity College Dublin and the Marine Research Institute of the Spanish Research Council (IIM-CSIC) in Vigo (Galicia, Spain), suggests 'subterranean estuaries' may be critical in managing sustainable fishing and aquaculture -- two growing industries of global importance.
A new study provides an in-depth look into the rich diversity of prey that giant plumose anemones consume. This includes a surprising menu item: ants. And the occasional spider.
A new United Nations report calls for an urgent change in the way the world's oceans are managed.
Researchers at William & Mary's Virginia Institute of Marine Science reveal that intensification of major oyster disease was due to evolving parasite, not just drought as previously thought.
Marine scientists assessed the risk posed by small-scale fisheries to all 72 species of toothed whales found throughout the world's oceans. They found that this risk was highest in the Central Indo-Pacific, Temperate Northern Pacific, Temperate South America and the Western Indo-Pacific.
Conditions during Baltic herring spawning may have cascading effects on the whole Baltic ecosystem.
