The fungal infection that has killed a record number of amphibians worldwide leads to deadly dehydration in frogs in the wild, according to a new study by University of California, Berkeley and San Francisco State University researchers. View More (2012-04-26)
USF study: Common fungicide wreaks havoc on freshwater ecosystems
Chlorothalonil, one of the world's most common fungicides used pervasively on food crops and golf courses, was lethal to a wide variety of freshwater organisms in a new study, University of South Florida researchers said Wednesday. View More (2012-05-17)
Spring fishing season arrives... and with it, amphibian diseases
Waterdogs, they're called, these larvae of tiger salamanders used as live bait for freshwater fishing. View More (2009-04-08)
Ancient fossils shed light on anatomical changes accompanying evolution of first land vertebrates
Cartoon depictions of the first animals to emerge from the ocean and walk on land often show a simple fish with feet, venturing from water to land. View More (2009-07-07)
Penn Research Using Frog Embryos Leads to New Understanding of Cardiac Development
During embryonic development, cells migrate to their eventual location in the adult body plan and begin to differentiate into specific cell types. View More (2011-04-25)
Decline in snow cover spells trouble for many plants, animals
For plants and animals forced to tough out harsh winter weather, the coverlet of snow that blankets the north country is a refuge, a stable beneath-the-snow habitat that gives essential respite from biting winds and subzero temperatures. View More (2013-05-08)
Caribbean frog populations started with single, ancient voyage on South American raft
Nearly all of the 162 land-breeding frog species on Caribbean islands, including the coqui frogs of Puerto Rico, originated from a single frog species that arrived on a sea voyage from South America. View More (2007-06-11)
New study points to agriculture in frog sexual abnormalities
A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. View More (2008-07-07)
80 percent of 'irreplaceable' habitats in Andes unprotected
Hundreds of rare, endemic species in the Central Andes remain unprotected and are increasingly under threat from development and climate change, according to a Duke University-led international study. View More (2012-01-27)
Living the high life is risky business for toads under threat from fungus
Midwife toads that live in the mountains are highly likely to die from a serious fungal infection, called chytridiomycosis, whereas their infected relatives in the lowlands are not, according to new research published today in Ecology Letters. View More (2010-01-25)
Freezing, preserving sperm vital to saving 'snot otter' salamanders
The hellbender salamander - known affectionately as a snot otter or devil dog - is one of America's unique giant salamander species. For unexplained reasons, most hellbender populations have rapidly declined as very little reproduction has occurred in recent decades. View More (2010-08-05)
Pesticide atrazine can turn male frogs into females
Atrazine, one of the world's most widely used pesticides, wreaks havoc with the sex lives of adult male frogs, emasculating three-quarters of them and turning one in 10 into females, according to a new study by University of California, Berkeley, biologists. View More (2010-03-02)
Biodiversity Protects Against Disease, Scientists Find
The richer the assortment of amphibian species in a pond, the more protection that community of frogs, toads and salamanders has against a parasitic infection that can cause severe deformities, including the growth of extra legs. View More (2013-02-15)
How to mend a broken heart: Advances in parthenogenic stem cells
Parthenogenesis is a form of asexual reproduction during which unfertilized eggs begin to develop as if they had been fertilized. View More (2013-02-25)
Why are there so many more species of insects? Because insects have been here longer
J. B. S. Haldane once famously quipped that "God is inordinately fond of beetles." Results of a study by Mark A. McPeek of Dartmouth College and Jonathan M. Brown of Grinnell College suggest that this fondness was expressed not by making so many, but rather by allowing them to persist for so long. View More (2007-04-04)
Mexican salamander helps uncover mysteries of stem cells and evolution
Dr Andrew Johnson is speaking today (12 July) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell...

Underestimation of frog numbers causes concern
Frogs are vanishing from all the world's ecosystems with unprecedented speed. It is thought that more than 100 species have died out since 1980 alone. View More (2007-10-31)
Scientists identify Ecuador's Yasuni National Park as one of most biodiverse places on earth
A team of scientists has documented that Yasuní National Park, in the core of the Ecuadorian Amazon, shatters world records for a wide array of plant and animal groups, from amphibians to trees to insects. View More (2010-01-20)
Secret of eternal youth may be in reptiles
Jo'£o Pedro Magalh'£es, researcher in the Biology of Aging, suggests, in work published in the June edition of the magazine "Experimental Gerontology" and entitled "The evolution of mammalian aging", that the study of certain species of reptiles and amphibians that apparently do not age could lead to discoveries about aging. For this Portuguese scientist the secret of eternal youth... View More (2002-06-18)
Priority regions for threatened frog and toad conservation in Latin America
Nearly 35% of all amphibians are now threatened of extinction raising them to the position of the most endangered group of animals in the world. View More (2008-05-07)
