  • Bufo
  • In the last few years our interest has been devoted to the energy metabolism of the eggs of the common toad Bufo arenarum Hensel which, like some other amphibian eggs, can cleave at a normal rate in the absence of oxygen or in the presence of cyanide (Barbieri & Legname, 1957). (biologists.org)
  • They occur in the parotoid glands, skin and poison of many toads (genus Bufo) and other amphibians, and in some plants and mushrooms. (wikipedia.org)
  • Anura
  • Progress towards a taxonomic revision of the Asian Bufo viridis group: Current status of nominal taxa and unsolved problems (Amphibia: Anura: Bufonidae). (wikipedia.org)
  • populations
  • Over time, the data which Frogloggers collect will help biologists and land managers know where each species occurs and in what abundance, and will help them make good decisions which benefit our amphibian populations, our environment and ourselves. (tn.gov)
  • in recent decades there has been a dramatic decline in amphibian populations for many species around the globe. (wikipedia.org)
  • Scientists monitoring stable populations of 49 amphibian species listened and watched as they crashed in just two years, with 20 native species disappearing completely-including the golden toad, found nowhere else on Earth. (nwf.org)
  • Because amphibian populations naturally fluctuate-and because most herpetologists focus on a single region-it took time for the scientists to comprehend the global nature of the crisis. (nwf.org)
  • frog
  • The smallest amphibian (and vertebrate) in the world is a frog from New Guinea ( Paedophryne amauensis ) with a length of just 7.7 mm (0.30 in). (wikipedia.org)
  • In California's High Sierra, meadows rich with the call of amphibians such as the Yosemite toad and the yellow-legged frog became eerily silent. (nwf.org)
  • Amphibian herpesviruses might never have been studied had Luck√© (1934) not discovered that cells of the renal adenocarcinoma of the common leopard frog, Rana pipiens , frequently contain intranuclear acidophilic inclusion bodies similar to those found in herpes simplex infections and other viral diseases. (springer.com)
  • Currently, the only non-native amphibian naturalised in Western Australia (WA) is Limnodynastes tasmaniensis (Spotted Grass Frog), which was introduced to Kununurra in the 1970s, apparently during the relocation of several hundred transportable homes from Adelaide. (wikipedia.org)

  • birds
  • Amphibians have smaller range sizes than do birds or mammals, so if there is habitat loss in an area, they are more likely to be affected," says Chanson. (nwf.org)
  • assess
  • According to CI biologist and report coauthor Janice Chanson, participants lacked sufficient data to assess the status of nearly 1,300 amphibian species. (nwf.org)
  • Scientists
  • It is widely accepted by a broad spectrum of scientists and philosophers that non-human animals can perceive pain, including pain in amphibians. (wikipedia.org)
  • available
  • This chapter will summarize the relevant available information on the two amphibian herpesviruses and, where possible, point out reasons for the paucity of information on them. (springer.com)
  • world
  • Amphibians are the lifeblood of many environments, playing key roles in the function of ecosystems, and it is both extraordinary and terrifying that in just a few decades the world could lose half of all these species," said Sir David Attenborough, famed for his television nature shows.

  • Amphibian Species of the World: an online reference. (wikipedia.org)
  • Groups
  • This means that advocates of phylogenetic nomenclature have removed a large number of basal Devonian and Carboniferous amphibian-type tetrapod groups that were formerly placed in Amphibia in Linnaean taxonomy, and included them elsewhere under cladistic taxonomy. (wikipedia.org)
  • human
  • In Java, amphibian species commonly collected for human consumption include Limnonectes macrodon, Fejervarya cancrivora, Fejervarya limnocharis, and Fejervarya iskandari. (wikipedia.org)
  • time
  • David Wake, a University of California-Berkeley biologist who has studied amphibians for 40 years, recalls the first time he returned to Monteverde after the crash: "I had the perspective of the forest becoming silent, of what had been just an incredible experience suddenly turning into nothing. (nwf.org)
  • international
  • In response to these declines in North America, an international group of biologists created the North American Amphibian Monitoring Program (NAAMP) , with the goal of providing reliable methods of monitoring our native amphibians. (tn.gov)
  • state
  • The TAMP is sponsored by the Tennessee Wildlife Resources Agency (TWRA) and the Center For Environmental Education at Middle Tennessee State University.Participation in the Tennessee Amphibian Monitoring Program is voluntary and is open to all interested persons, old and young alike. (tn.gov)
  • The TAMP is being undertaken in an effort to understand the status of amphibians in our home state. (tn.gov)
  • Fossil records of Amphibia have been identified in the north west of the state. (wikipedia.org)
  • The Wyoming Toad or Baxter's Toad (Bufo baxteri or Anaxyrus baxteri) is an extremely rare amphibian that exists only in captivity and within Mortenson Lake National Wildlife Refuge in the U.S. state of Wyoming. (wikipedia.org)
  • fish
  • The earliest amphibians evolved in the Devonian period from sarcopterygian fish with lungs and bony-limbed fins, features that were helpful in adapting to dry land. (wikipedia.org)
