A study of venomous snails on remote Pacific islands reveals genetic underpinnings of an ecological phenomenon that has fascinated scientists since Darwin. The research, by University of Michigan evolutionary biologists Tom Duda and Taehwan Lee, is scheduled to be published online May 20 in the open-access journal PLoS ONE. In the study, Duda and Lee explored ecological release, a phenomenon thought to be responsible for some of the most dramatic diversifications of living things in Earth's...

Everything is coming up roses for snails with slower metabolic rates, Chilean researchers have found. This is the first instance that natural selection has chosen this trait in any kind of species.  These snails have a leg up over others because they reserve more energy for other actions like growth or mating, says the findings, available in the journal Evolution. Roberto Nespolo and Paulina Artacho from the Southern University of Chile reviewed an old hypothesis called the "energetic...

University of California, Berkeley, graduate student Alistair Boettiger has amassed a beautiful collection of seashells, but not by combing the beach. He created them in his computer.He and George Oster, a UC Berkeley biophysicist, along with University of Pittsburgh mathematical neuroscientist Bard Ermentrout, have written a computer program that generates the complex patterns of seashells using simple principles developed to explain how the brain works and how memories are stored.The...

U.S. biologists have finished a study started in 1915, determining snail shells can significantly increase in size during a relatively short period of time. The University of Pennsylvania researchers focused on the snail Nucella lapillus and found the snail experienced a dramatic increase in the size of its shell during less than a century, providing a clear illustration of how fast and effectively change can occur. The biologists said their most striking finding, which was not previously...

A team of biologists at the University of Pennsylvania has completed a research study begun in 1915 and determined that a snail making its home in the northwest Atlantic Ocean around Mount Desert Island, Me., has experienced a dramatic increase in the size of its shell during less than a century, providing a clear illustration of how fast and effectively change can occur. The study is published in the current issue of the Proceedings of the National Academy of Sciences. The most striking...

Change has important implications for the marine ecosystem A Queen's University biologist has discovered that the shell lengths of northwest Atlantic Ocean snails "“ an important member of the Atlantic food chain "“ have increased by 22.6 per cent over the past century. Until now, this significant change in the marine ecosystem has gone unnoticed. "We found a dramatic increase in size, which could affect the entire intertidal food chain," says Jonathan Fisher, Queen's Postdoctoral...

Genes determining asymmetry probably arose in the first bilaterally symmetric organisms Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body. The finding, reported online in advance of publication in Nature by University of California, Berkeley, researchers, indicates that the same genes have been responsible for establishing the left-right asymmetry of animals...

Scientists are looking to outer space for help in their attempt to prevent new outbreaks of the tropical disease schistosomiasis in southern China. Once the Three Gorges Dam is fully operational, researchers plan to use satellite data from space to determine whether changing water conditions in Poyang Lake, China's largest freshwater lake, create favorable conditions for the snails associated with the chronic disease that can damage internal organs and impair growth and cognitive development...

Hawaii's ongoing problem with invasive species such as snails and slugs, including their serious impact on plant nurseries and other aspects of the local horticultural industry, has been investigated and documented by four University of Hawaii at Mānoa researchers. It is the first documented baseline compilation of the distributions of all snail and slug species associated with the horticultural industry throughout the Hawaiian Islands. In an October-December 2008...

By Jenny Haworth Environment Correspondent IT MAY be only the size of a grain of sand, but despite its tiny stature giant steps have been taken to protect the narrow-mouthed whorl snail. Measuring less than a millimetre across, the snail is one of the smallest in the world and one of the rarest. A 15-hectare spot near Stonehaven is the last stronghold for the creature in Scotland. Yesterday the site at Garron Point - about half the size of the Royal Botanic Garden in Edinburgh -...
