Australian Great White Sharks Are Actually Two Distinct Species
2012-06-05 11:14:06

Brett Smith for redOrbit.com Despite inhabiting the same waters, two populations of Great White sharks living in the coastal waters of Australia are genetically distinct, according to a new study published in the journal Marine Ecology Progress Series. The two groups of Great Whites, or white sharks, are separated by the Bass Strait, a stretch of water between the Australian mainland and Tasmania to the south. The research team, led by Dean Blower from the University of Queensland, used...

Study Finds Drastic Decline in Reef Shark Population
2012-04-29 04:40:15

An international team of marine scientists has discovered that the population of reef sharks living the Pacific Ocean have decreased by at least 90% over the past several decades, claims a new study published online Friday in the journal Conservation Biology. As part of the study, a group of eight scientists used underwater surveys collected over the past 10 years from 46 different US Pacific islands and atolls as part of the National Oceanic and Atmospheric Association (NOAA) Pacific Reef...

sharksScientists Provide First Large-Scale Estimate of Reef Shark Losses in The Pacific Ocean

Tales from towed diver surveys demonstrate sobering truth about these top predators Many shark populations have plummeted in the past three decades as a result of excessive harvesting — for their fins, as an incidental catch of fisheries targeting other species, and in recreational fisheries. This is particularly true for oceanic species. However, until now, a lack of data prevented scientists from properly quantifying the status of Pacific reef sharks at a large geographic scale....

Research Suggests Ecotourism May Help, Not Harm, Wildlife
2012-03-10 06:31:14

A new study investigating the impact of ecotourism activities that use food to attract wildlife for observers has discovered that the booming business does not appear to have a negative effect on those creatures. In fact, researchers at the University of Miami's (UM) Rosenstiel School of Marine & Atmospheric Science have discovered that the opposite may very well be true -- ecotourism may be good for the creatures that are becoming so highly sought after by would-be onlookers. Their...

Sharks More Prevalent In Protected Areas, Study Claims
2012-03-10 06:22:33

Using data collected from over 200 baited remote underwater video (BRUV) cameras, scientists have discovered that Caribbean reef sharks are more abundant in marine reserves than in areas where fishing is allowed. The BRUV cameras, affectionately dubbed "chum cams," were placed both inside and outside aquatic reserve areas on the Mesoamerican Barrier Reef in the Caribbean Sea by researchers from the Stony Brook University Institute for Ocean Conservation Science. Their goal was to test a...

Shark fins are worth more than other parts of the shark and are often removed from the body, which gets thrown back into the sea. To curtail this wasteful practice, many countries allow the fins to be landed detached from shark bodies, as long as their weight does not exceed five per cent of the total shark catch. New University of British Columbia research shows that this kind of legislation is too liberal. A study published this week in the journal Fish Biology analyzes the fin to body...

Australia Waters Harbor Hybrid Sharks
2012-01-03 08:09:49

Marine scientists from the University of Queensland have discovered hybridized sharks off Australia´s east coast, leading them to believe that some of these predatory beasts display a tendency to interbreed, challenging long-standing scientific theories regarding shark behavior. This is the first time scientists have confirmed a substantial number of hybrid sharks off Australia´s coast, speculating that it may be an adaptation or reaction to climate change; and scientists now...
