Shift of Nitrogen and Carbon Stable Isotopes in Temporary Pond Tadpoles Following the Decline of Large Mammalian Herbivores

Ecology and Evolution
Nutrient cycling across ecosystems is driven by complex ecological interactions, potentially impacting environmental stability. Savanna ecosystem processes are highly driven by large mammalian herbivores, so removing them likely causes significant ...

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Transcriptomic Changes in Hot Spring Frog Tadpoles (Buergeria otai) in Response to Heat Stress

Frontiers in Ecology and Evolution, 2021
Buergeria frog tadpoles exhibit high thermal tolerance and are occasionally found in water pools that temporarily exceed 40°C. With the aim of understanding how they can cope with the severe heat stress, we performed RNA-seq of three heat-treated (38°C ...

Fossils Reveal Long-Term Continuous and Parallel Innovation in the Sacro-Caudo-Pelvic Complex of the Highly Aquatic Pipid Frogs

Frontiers in Earth Science, 2019
Within the already peculiar Bauplan of anurans, pipid frogs have evolved an array of bizarre features that are commonly linked to their highly aquatic lifestyle. Among the latter, there are several distinctive sacro-caudo-pelvic features shared by extant
