Discovery in the evolution of the immune system absorbing cells
Led by Dr J Oriol Sunyer, of the Faculty of Veterinary Medicine at the University of Pennsylvania, and formed by researchers from Philadelphia, St Louis and Idaho (USA) and by Dr Lluís Tort of the Universitat Autònoma de Barcelona, the group has been able to show that B cells in fish as well as in amphibians are capable of strong phagocytosis... view more...

Study Confirms Amphibians' Ability to Predict Changes in Biodiversity
Biologists have long suspected that amphibians, whose moist permeable skins make them susceptible to slight changes in the environment, might be good bellwethers for impending alterations in biodiversity during rapid climate change. view more (2008-10-29)
The first gene-encoded amphibian toxin isolated
Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison. view more (2009-08-18)
Global map shows new patterns of extinction risk
The most detailed world map of mammals, birds and amphibians ever produced shows that endangered species from these groups do not inhabit the same geographical areas, says new research published today. view more (2006-11-02)
Amphibians as environmental omen disputed
Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters. view more (2009-11-12)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Amphibians in losing race with environmental change
Even though they had the ability to evolve and survive for hundreds of millions of years - since before the time of the dinosaurs and through many climatic regimes - the massive, worldwide decline of amphibians can best be understood by their inability to keep pace with the current rate of global change, a new study suggests. view more (2007-05-01)
Study rules out inbreeding as cause of amphibian deformities
Although research has linked inbreeding with elevated rates of deformity in a wide variety of animals, a new study finds it plays no part in the high incidence of malformation among salamanders. view more (2008-10-29)
Colombian Frog Believed Extinct Found Alive
Researchers exploring a Colombian mountain range found surviving members of a species of Harlequin frog believed extinct due to a killer fungus wiping out amphibian populations in Central and South America. view more (2006-05-19)
Experts develop global action plan to save amphibians facing extinction
A summit of leading scientists have agreed to an action plan intended to save hundreds of frogs, salamanders and other amphibians facing extinction from familiar threats such as pollution and habitat destruction, as well as a little-known fungus wiping out their populations. view more (2005-09-21)
New findings on immune system in amphibians
Krakow/Halle. Major Histocompatibility Complex (MHC) genes produce proteins that are crucial in fighting pathogen assault. Researchers from the Jagiellonian University in Krakow and from the Helmholtz Centre for Environmental Research (UFZ) characterized genetic variation and detected more than one MHC class II locus in a tailed amphibian. view more (2008-06-20)
Climate change drives widespread amphibian extinctions
Results of a new study provide the first clear proof that global warming is causing outbreaks of an infectious disease that is wiping out entire frog populations and driving many species to extinction. view more (2006-01-12)
Mangrove-dependent animals globally threatened
More than 40 percent of a sample of amphibians, reptiles, mammals, and birds that are restricted to mangrove ecosystems are globally threatened with extinction, according to an assessment published in the July/August issue of BioScience. view more (2009-07-01)
Ancient amphibians evolved a bite before migrating to dry land
Ancient aquatic amphibians developed the ability to feed on land before completing the transition to terrestrial life, researchers from Harvard University report this week in the Proceedings of the National Academy of Sciences. view more (2007-04-17)
Wildlife researchers identify impacts of contamination in amphibians
Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech's College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been proven for other vertebrates. view more (2006-02-22)
Smithsonian scientists find the frog legs trade may facilitate spread of pathogens
Most countries throughout the world participate in the $40-million-per-year culinary trade of frog legs in some way, with 75 percent of frog legs consumed in France, Belgium and the United States. view more (2009-11-20)
Leeches ferry infection among newts
Parasite-carrying bloodsucking leeches may be delivering a one-two punch to newts, according to biologists, who say the discovery may provide clues to disease outbreaks in amphibians. view more (2007-02-01)
Ancient Amphibians Left Full-Body Imprints
Unprecedented fossilized body imprints of amphibians have been discovered in 330 million-year-old rocks from Pennsylvania. The imprints show the unmistakably webbed feet and bodies of three previously unknown, foot-long salamander-like critters that lived 100 million years before the first dinosaurs. view more (2007-10-31)
New study reveals large scale conservation essential
Scientists were surprised with findings of a recent study that reveals many animal species believed to persist in small contained areas actually need broad, landscape level conservation to survive. view more (2008-06-10)
A missing link settles debate over the origin of frogs and salamanders
The description of an ancient amphibian that millions of years ago swam in quiet pools and caught mayflies on the surrounding land in Texas has set to rest one of the greatest current controversies in vertebrate evolution. The discovery was made by a research team led by scientists at the University of Calgary. view more (2008-05-22)
