Amphibians / Amphibien / Anfibios

Amphibian

Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia.Modern amphibians are all Lissamphibia.They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems.Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.

Amphibian Survival Alliance

Conserving amphibians has never been more important. Around half of all amphibian species are declining, and the proportion threatened with extinction is thought to be over 40%, making amphibians the most threatened vertebrate group. Once a sanctuary for over 8,000 species, we now live in a world that is increasingly unsafe for amphibians.

Amphibian Pictures & Facts National Geographic

Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts.

A comprehensive assessment (more than 250 references) of how the application of evolutionary principles and approaches can improve conservation outcomes for amphibians (Pabijan et al. 2020) offers many examples and insights.A surprising number of negative effects can arise from invasive species and from introgression and hybridization, but there are also some known salutary effects.
