Effects of temperature and volume of water on the growth and development of tadpoles of Pleurodema diplolister and Rhinella granulosa (Amphibia: Anura)

open access: yesZoologia (Curitiba), 2009
The capacity of tadpoles to reduce their metamorphosis time and body size in response to fluctuations in environmental variables of temporary ponds has been recorded in field and laboratory studies. The main alterations in this habitat are related to the

A review of chemical defense in harlequin toads (Bufonidae; Atelopus)

open access: yesToxicon: X, 2021
Toads of the genus Atelopus are chemically defended by a unique combination of endogenously synthesized cardiotoxins (bufadienolides) and neurotoxins which may be sequestered (guanidinium alkaloids). Investigation into Atelopus small-molecule chemical defenses has been primarily concerned with identifying and characterizing various forms of these ...

Systematics of the endangered toad genus Andinophryne (Anura: Bufonidae): phylogenetic position and synonymy under the genus Rhaebo.

open access: yes, 2015
Bufonidae is one of the most diverse amphibian families. Its large-scale phylogenetic relationships are relatively well understood with the exception of few Neotropical genera that may have diverged early in the evolution of the family.

Frog tongue surface microstructures: functional and evolutionary patterns

open access: yesBeilstein Journal of Nanotechnology, 2016
Frogs (Lissamphibia: Anura) use adhesive tongues to capture fast moving, elusive prey. For this, the tongues are moved quickly and adhere instantaneously to various prey surfaces.

Positive Darwinian selection results in resistance to cardioactive toxins in true toads (Anura: Bufonidae)

open access: yes, 2016
Members of the Family Bufonidae, true toads, are famous for their endogenously synthesized cardioactive steroids that serve as defensive toxins. Evolution of resistance to these toxins is not understood.

Skin Resistance to Dehydration: A Theory‐Informed Trait Gradient in Anurans

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Aim Anurans' sensitivity to hydric stress has driven adaptive changes in multiple traits, potentially displaying geographical clines, as is the case with body size. A longstanding body of research suggests that skin resistance to water loss may also vary geographically in response to water loss.
