Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

UCSB scientists see possible biomedical applications Scientists at UC Santa Barbara have discovered a caste of genetically identical "warrior worms" "“"“ members of a parasitic fluke species that invades the California horn snail. The findings are reported in the early online version of the Proceedings of the Royal Society B. "We have discovered flatworms in colonies with vicious, killer morphs defending the colony," said Armand M. Kuris, professor of zoology, in the Department of...

 The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in this week's Current Biology.The scientists' report represents direct experimental evidence for the "Red Queen Hypothesis" of sex, which suggests sexual reproduction allows host species to avoid infection by their...

WASHINGTON -- The growing number of deformed frogs in recent years is caused at least partly by runoff from farming and ranching, new research indicates. Nitrogen and phosphorous in the runoff fuel a cycle that results in a parasitic infection of tadpoles, resulting in loss of legs, extra legs or other deformities, according to researchers led by Pieter Johnson of the University of Colorado, Boulder. Their findings are being published in this week's online edition of Proceedings of the...

Scientists have discovered that parasites are surprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences. Scientists with the University of California, Santa Barbara, the U.S. Geological Survey, and Princeton University contributed. The report describes a study performed in Santa Barbara County at the Carpinteria Salt Marsh. Carpinteria Salt Marsh Reserve is...
