Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply
Fewer big sharks in the oceans mean that bay scallops and other shellfish may be harder to find at the market, according to an article in the March 30 issue of the journal Science, tying two unlikely links in the food web to the same fate. view more (2007-03-30)
UF scientists trace origin of shark's electric sense
Sharks are known for their almost uncanny ability to detect electrical signals while hunting and navigating. view more (2006-02-07)
New piece in the jigsaw puzzle of human origins
In an article in today's Nature, Uppsala researcher Martin Brazeau describes the skull and jaws of a fish that lived about 410 million years ago. The study may give important clues to the origin of jawed vertebrates, and thus ultimately our own evolution. view more (2009-01-16)
How marine reserves are giving coral reefs a helping hand
It may be no surprise that marine reserves protect the fish that live in them, but now scientists from the University of Exeter have shown for the first time that they could also help improve the health of coral reefs. view more (2006-01-06)
Conquest of land began in shark genome
When the first four-legged animals sprouted fingers and toes, they took an ancient genetic recipe and simply extended the cooking time, say University of Florida scientists writing in Wednesday's issue of the journal PLoS ONE. view more (2007-08-15)
Satellite technology allows scientists to track warm sharks in cold polar seas
Electronic tags broadcasting from the dorsal fins of salmon sharks reveal that these top predators migrate from the glacial waters of Alaska to the warm seas off Hawaii. view more (2005-10-07)
World interest in Australian fishery impact test
An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. view more (2009-10-28)
Loss of top predators causing surge in smaller predators, ecosystem collapse
The catastrophic decline around the world of "apex" predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller "mesopredators" that are causing major economic and ecological disruptions, a new study concludes. view more (2009-10-02)
Extinction threats grow as sea governance rules ignored
Those who rule the ocean waves are being named and shamed today for their role in failing to prevent the near extinction of the albatross. view more (2005-03-03)
World shark attacks dipped in 2005, part of long-term trend
Assertive and even aggressive human behavior could explain why shark attacks worldwide dipped last year, continuing a five-year downward trend in close encounters with the oceanic predators. view more (2006-02-14)
Human deaths from shark attacks hit 20-year low last year
Fatal shark attacks worldwide dipped to their lowest levels in two decades in 2007 with the sole casualty involving a swimmer vacationing in the South Pacific, according to the latest statistics from the University of Florida. view more (2008-02-13)
Ancient predator had strongest bite of any fish, rivaling bite of large alligators and T. rex
t could bite a shark in two. It might have been the first "king of the beasts." And it could teach scientists a lot about humans, because it is in the sister group of all jawed vertebrates. view more (2006-11-29)
Adolescents, risks and the pitfalls of rationality
Is it a good idea to swim with sharks? Is it smart to drink a bottle of Drano? What about setting your hair on fire - is that a good thing to do? view more (2006-11-14)
Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts. view more (2008-02-12)
Rare albino ratfish has eerie, silvery sheen
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound. view more (2007-09-25)
U of A researcher has rare evidence of dinosaur cannibalism
University of Alberta researcher Phil Bell has found 70 million year old evidence of dinosaur cannibalism. view more (2009-10-07)
UF study: World shark attacks rise slightly but continue long-term dip
Shark attacks edged up slightly in 2006 but continued an overall long-term decline as overfishing and more cautious swimmers helped take a bite out of the aggressive encounters, new University of Florida research finds. view more (2007-02-14)
Equations against hypothermia
Sharks are, by tradition, the eternal threat facing divers. Yet, a diver is quite a lot more unlikely to meet such a creature under the water than, at some time or another, to come up against an even greater danger - hypothermia, or exposure. To enable divers to prevent this syndrome from creeping silently up on them, two researchers from the Area... view more... (2004-09-01)
Historical Photographs Expose Decline in Florida's Reef Fish, New Scripps Study Finds
A unique study by a scientist at Scripps Institution of Oceanography at UC San Diego has provided fresh evidence of fishing's impact on marine ecosystems. view more (2009-02-18)
Mixed dolphins and the impact of tourism
Dolphins off the coast of East Africa are exposed to a number of threats, like indirect catching, hunting, and environmental impact. In her dissertation at the Department of Zoology, Stockholm University, Sweden, Eva Stensland has studied behavioral ecology in Indo-Pacific bottlenose and humpback dolphins, off Zanzibar, Tanzania. For the last... view more... (2004-05-07)
