Contents: Introduction Map of Global Declines Why are Populations Declining? Factors Involved in Amphibian Decline ... Recent Scientific Publications Amphibians, a unique group of vertebrates containing over 6,300 known species, are threatened worldwide. A recent assessment of the entire group (globalamphibians.org) found that nearly one-third (32%) of the world’s amphibian species are threatened, representing 1,856 species. Amphibians have existed on earth for over 300 million years, yet in just the last two decades there have been an alarming number of extinctions, nearly 168 species are believed to have gone extinct and at least 2,469 (43%) more have populations that are declining. This indicates that the number of extinct and threatened species will probably continue to rise (Stuart et al. 2004). Amphibian diversity is highest in the tropics and Brazil has the most described species at 789 species, by contrast, the United States has 291 species but is nearly the same size (as of January 16,2008). Declines have occured around the world, the areas that have suffered the most declines include Central America, the Caribbean, and Australia.

Scientists at the Zoological Society of London (ZSL) are currently researching the diseases affecting amphibians, with particular focus on the chytrid fungus, which is implicated in mass mortality events globally.

26. Amphibian Ark An international partnership to ensure the global survival of amphibians, especially those that cannot be safeguarded in nature. http://www.amphibianark.org/

Keeping threatened amphibian species afloat Deutsch English Español Search Welcome to the Amphibian Ark Amphibians are an important component of the global ecosystem, as indicators of environmental health and contributors to human health. They watched the dinosaurs come and go, but today almost half of them are themselves threatened with extinction. Addressing the amphibian extinction crisis represents the greatest species conservation challenge in the history of humanity. The global conservation community has formulated a response in the Amphibian Conservation Action Plan, and an integral part of that response is the Amphibian Ark, in which select species that would otherwise go extinct will be maintained in captivity until they can be secured in the wild. Without immediate captive management as a stopgap component of an integrated conservation effort, hundreds of species could become extinct. Amphibian Ark Global Campaign: "2008 Year of the Frog" During 2008, AArk is leading zoos in a globally coordinated public awareness campaign “The Year of the Frog.” The main goal of this campaign is to generate public awareness and understanding of the amphibian extinction crisis A message from Sir David Attenborough,

Herpetology Lab HomePage A mphibians and reptiles are important, but often overlooked, components of many southeastern ecosystems. Recently, many amphibian and reptile populations have experienced drastic declines, thus increasing the need for studies of their biology and conservation. Many amphibians and reptiles may be especially susceptible to environmental degradation, thus making them potentially important indicators of overall environmental health. The purpose of this web site is to foster an appreciation of amphibians and reptiles and to provide information regarding their biology and conservation, focusing on those species occuring in North Carolina. On this web site, you will find information on every species of amphibian and reptile found in North Carolina, information on conservation efforts in North Carolina, and an interesting section on amphibian and reptile facts and myths. Finally, you will also find an extensive website describing the outreach efforts of the Davidson College Herpetology Lab.

31. Amphibians In Kansas Currently, there are about 4000 recognized species of amphibians in the world, divided into 3 living orders. Within Kansas 30 species and subspecies are http://www.gpnc.org/amphibia.htm

Amphibians Are in the class Amphibia within the subphylum Vertebrata. Are cold-blooded. They cannot maintain their body temperature by internal means. Have a moist skin with no protective scales or shells. Lay soft, gelatinous eggs with no shell Lay their eggs in water or some other situation where they will remain moist. Start their life in the water in a gilled larval state (called tadpoles in frogs and toads). Have no claws on their toes. Currently, there are about 4,000 recognized species of amphibians in the world, divided into 3 living orders. Within Kansas 30 species and subspecies are recorded from 9 families in 2 orders. The following list is adapted from "A Checklist of the Vertebrate Animals of Kansas", 3rd edition, 2005, by George Potts and Joseph Collins.

Amphibians: Why Study Them? (Click on a picture to learn more...) Amphibians are a convenient system for studying vertebrate development for several reasons: They're vertebrates . While that is obvious, historically amphibians were the only vertebrate that could be easily studied using experimental techniques. Not only are they vertebrates, but amphibians (except for caecilians, an unusual order of amphibians) are tetropods, so they have all of the fundamental features of land-dwelling vertebrates. They undergo external development , so they can be observed and relatively easily manipulated. They are physically large . Mature Xenopus oocytes are 1 mm in diameter, which is an order of magnitude larger than a mouse oocyte, for example. Ambystoma oocytes are even larger. Their development is relatively rapid; they go from fertilization through neurulation in approximately 18 hrs. at 22 deg. C.

This animal class includes toads and frogs, salamanders and newts, and caecilians. Almost all amphibians have thin, moist skin that helps them breathe. No other group of animals has this special skin. Most amphibians undergo a unique change from larvae to adults, called metamorphosis. All amphibians are ectotherms (what used to be called "cold-blooded"), a trait they share with invertebrates, fish, and reptiles. Thin-skinned Most amphibians have thin skin that is very permeable (allowing liquids and gases to pass through it easily). This is important for two reasons. First, it means that their skin helps them breathe, since oxygen passes easily through it. Second, it means that amphibians lose a lot of water through their skin. This is why most amphibians are found in moist or humid environments, where they can re-load their water reserves. Leading a Double-Double Life The word amphibian comes from the Greek word amphibios , meaning "a being with a double life." Some say their name refers to the fact that amphibians live in two places on land and in water. While dual residence
