Researcher Finds 'Goldilocks' Effect In Snail Populations
2013-12-04 08:18:59

University of Iowa Finding may one day help control invasive species A University of Iowa researcher has discovered that a “Goldilocks” effect applies to the reproductive output of a tiny New Zealand snail—considered a troublesome species in many countries—that may one day help environmentalists control their spread. Known in the United States as the “New Zealand mud snail,” the freshwater snail (Potamopyrgus antipodarum) grows to a length of about one-quarter inch in...

Aquatic Invader That Can Survive Without Water

Nowadays, an increasing number of rivers and lakes are being invaded by exotic snails, which come from remote regions, and even other continents. Such species represent a threat to native species, as they compete for food or space with them. This is the case of the mudsnail (Potamopyrgus antipodarum). This small aquatic snail is native to New Zealand, and has spread throughout rivers, lakes or streams in Europe, Australia, America and Asia. The invasion success of this mudsnail may be...

A new minute freshwater snail species belonging to the genus Daphniola was found by a researcher from University of Athens (Canella Radea) in a spring covered by snow on Mt. Parnassos, central Greece. This study was published in the open access journal Zookeys. The new species, Daphniola eptalophos, has a transparent conical-flat coiled shell, grey-black pigmented soft body and a black penis with a small colorless outgrowth on the left side near its base. D. eptalophos differs from its...

Living organisms have good reason for engaging in sexual, rather than asexual, reproduction according to Maurine Neiman, assistant professor of biology in the UI College of Liberal Arts and Sciences and researcher in the Roy J. Carver Center for Genomics. In an article published in a recent issue of the journal Molecular Biology and Evolution, she and her colleagues, including John M. Logsdon Jr., associate professor of biology, examined the theory that sexual reproduction, while requiring...

U.S. scientists say the New Zealand mud snail, long a problem in western states, has spread across four U.S. Great Lakes and is altering the lakes' ecology. Pennsylvania State University scientists said the tiny snails out-compete native snails and insects but aren't good fish food replacements for the native species. "These snails have an operculum, a door that closes the shell," said Associate Professor Edward Levri at the university's Altoona, Pa., campus. "They can be out of the water...
