Newly found species fills evolutionary gap between fish and land animals
Paleontologists have discovered fossils of a species that provides the missing evolutionary link between fish and the first animals that walked out of water onto land about 375 million years ago. view more (2006-04-06)
Slightly stressed carp succumb easily to parasite
Researchers from Wageningen have discovered that slightly stressed carp are much more susceptible to parasites than unstressed carp. All of the laboratory carp which were taken out of the water for one minute a day, died from parasitic attack. Only 40% of the carp who did not undergo the light stress treatment died from the parasites. The... view more... (2002-09-11)
Smithsonian puts tropical Eastern-Pacific shore fishes online
A new bilingual online information system created by D. Ross Robertson, staff scientist at the Smithsonian Tropical Research Institute, and Coeus Knowledge Systems makes it possible for conservationists, sport fishers, tourists, researchers, students and resource managers to identify and generate publishable maps for 1,287 tropical eastern Pacific... view more...

Rainfall and river networks prove accurate predictors of fish biodiversity
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams. view more (2008-05-08)
Global warming increases species extinctions worldwide
Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist. view more (2006-11-15)
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)
Three new species of lemurs identified
Researchers have identified three new species of lemurs, the small, big-eyed primates native to the island of Madagascar. view more (2006-02-23)
Fish evolve a longer lifespan by evolving a longer reproductive period, researchers find
A UC Riverside-led research team has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of the lifespan that contributes to "fitness" - the relative ability of an individual to contribute offspring to the next generation. view more (2005-12-27)
Genetic analysis of cavefish reveals more about evolution
A multi-institutional study offers additional insight into the evolutionary process by examining how albinism evolves in cavefish. view more (2005-12-20)
Unusual fish-eating dinosaur had crocodile-like skull
An unusual dinosaur has been shown to have a skull that functioned like a fish-eating crocodile, despite looking like a dinosaur. It also possessed two huge hand claws, perhaps used as grappling hooks to lift fish from the water. view more (2008-01-14)
Scientists Conduct Shark Survey off U.S. East Coast
Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems. view more (2009-08-14)
Anti-inflammatory effects of omega 3 fatty acid in fish oil linked to lowering of prostaglandin
Omega 3 fatty acids in dietary fish oil are reported to have anti-inflammatory and anti-thrombogenic and anti-arrhythmic effects in humans, but the biochemical basis for these beneficial health effects is not well understood. view more (2006-04-04)
Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. view more (2008-11-19)
Evolution of new species slows down as number of competitors increases
The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology. view more (2008-03-25)
Ocean temperature predicts spread of marine species
Scientists can predict how the distance marine larvae travel varies with ocean temperature - a key component in conservation and management of fish, shellfish and other marine species - according to a new study from the University of North Carolina at Chapel Hill. view more (2006-12-26)
New paper examines dams' effects on California salmon
Spring-run Chinook salmon and other fish in the rivers of California's Central Valley could be harmed by more water-storage dams, according to researchers at Duke University and the National Oceanic and Atmospheric Administration. view more (2007-09-25)
Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...

Biodiversity conservation - no guarantee for shortcuts
New research from scientists at the University of Sheffield published in the November issue of Ecology Letters has cast doubts on the widely held `rule of thumb` that the conservation of a country`s biodiversity can be guaranteed by focusing on protecting its threatened and endemic species. In a report published this week, Aletta Bonn, Ana... view more... (2002-10-30)
'DEEP AND CRISP AND EATEN': THE SCOTTISH DEEP-FRIED MARS BAR (p 2180)
A letter in this week's issue of THE LANCET details a survey of Scottish fish and chip shops to try and estimate the popularity of the deep-fried Mars bar. view more (2004-12-15)
Researchers call for wider implementation of FISH testing in metastatic breast cancer
Accurate diagnostic assessment of HER2 is essential for the effective treatment of metastatic breast cancer. Results to be published in the April issue of the Journal of Pathology indicate that FISH testing has many advantages over other methods, however in the UK there are very few diagnostic laboratories with the expertise to carry out the test.... view more...
