According to the International Union for Conservation of Nature (IUCN), 93 reptile and amphibian species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR.
As of 2018, the Conservation Needs Assessment had been used in nearly 2,700 assessments for more than 2,300 species of amphibians, or about 31% of all known amphibian species. [15] These assessments focused on anurans at almost 2,400 assessments, while newts and salamanders made up nearly 300 of the assessments, and caecilians made up only ...
Blue poison dart frog. Herpetology (from Greek ἑρπετόν herpetón, meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras).
When amphibian declines were first presented as a conservation issue in the late 1980s, some scientists remained unconvinced of the reality and gravity of the conservation issue. [10] Some biologists argued that populations of most organisms, amphibians included, naturally vary through time.
Additionally, 1193 amphibian species (16.4% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 3 ]
They decided in the fall of 1957 to formalize interactions amongst a small group of amateur herpetologists throughout Ohio and began publishing a combined journal and newsletter (called the Trimonthly Report) in January 1958. [1] The name of the society was changed to The Society for the Study of Amphibians and Reptiles on January 1, 1967.
