Study of amphibians
Wake abandoned entomology for the study of amphibians and reptiles, a field known as herpetology. He focused much of his attention on one species-rich, but poorly understood, family of mostly North and Central American salamanders, the lungless salamanders, Plethodontidae, many of which lead an entirely terrestrial existence and consequently do ...Comments where more study is needed are also included where pertinent. Authors, dates, and original spellings of the higher-level taxonomy of all taxa covered herein are also given. A total of 401 species (137 amphibians and 264 reptiles) are now known from the country with 111 species (27.7%) being Honduran endemics (52 amphibians …Batrachology is a branch of Herpetology concerned with the study of amphibians alone. Ophiology (Snakes) Ophiology or Ophidiology is a sub-division of Herpetology which deals with the study of ophidians or snakes.

For example, the 1943 Nobel Prize in Chemistry went to George de Hevesy for his work on the use of isotopes as tracers in the study of chemical processes using amphibians. Evolution of Amphibians. Fossil evidence shows that amphibians evolved about 365 million years ago from a lobe-finned lungfish ancestor. As the earliest land vertebrates, they were highly successful. Some of them were much larger than today's amphibians. For more than 100 million years, amphibians remained the dominant land vertebrates.The lack of a comprehensive picture of the extent and severity of amphibian declines prompted us to conduct the IUCN–The World Conservation Union Global Amphibian Assessment (GAA) to gather data on the distribution, abundance, population trends, habitat associations, and threats for all 5743 described species of amphibians …
So basically, the entire evolutionary emergence of amphibians is re-acted again and again in each successive generation of amphibian species – like the frog.They estimated a phylogeny for 4061 amphibian species based on DNA sequence data. The taxonomy used in that study was adapted to follow the Amphibian Species of the World (ASW) online reference 9 using the AmphiNom package 89 in R v3.6.1 90. Changes were made to either update species names or prune them from the phylogeny if they represent ...The discipline of conservation biology emerged specifically to understand, quantify and ameliorate the current biodiversity crisis (Soulé, 1986). Amphibians are playing an increasingly prominent role in this issue. The current era of research into amphibian declines followed the First World Congress of Herpetology in 1989 (Wake, 1991, Wake ...Batrachology. Batrachology is the branch of zoology concerned with the study of amphibians including frogs and toads, salamanders, newts, and caecilians. It is a sub-discipline of herpetology, [1] which also includes non-avian reptiles ( snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuatara ).
Once successful, mating frogs must still repel assaults from single males, while maintaining an unbreakable grip. A recent study found that successful males had much thicker forelimbs and enlarged “nuptial pads,” a portion of the hand that assists in gripping the female. Talk about sexual selection. It is not always the male doing the …Oct 11, 2023 · Herpetology is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts and the gymnophiona) and reptiles (including snakes, lizards, amphisbaenids ... …
