April Flowers for redOrbit.com - Your Universe Online A new study from the University of Colorado, Boulder shows that the richer the biodiversity of amphibian species living in a pond, the more protection that ecosystem has against parasitic infections. The finding of the study support the broader theory that greater biodiversity in large-scale ecosystems such as forests or grasslands may also provide greater protection against diseases, including those that attack humans. A larger...

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...

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...
