Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Enzymatic activity of bone markers on Lithobates catesbeianus (Shaw, 1802) growth during the ossification process

open access: yesBrazilian Journal of Biology, 2021
In order to better understand the ossification processes in anurans our study was carried out on tadpoles and adults of Lithobates catesbeianus. In this sense, we characterized the kinetic properties of alkaline phosphatase with p-nitrophenylphosphatase (

Egg clutch dehydration induces early hatching in red-eyed treefrogs, Agalychnis callidryas [PDF]

open access: yes, 2017
Terrestrial eggs have evolved repeatedly in tropical anurans exposing embryos to the new threat of dehydration. Red-eyed treefrogs, Agalychnis callidryas, lay eggs on plants over water.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

open access: yesWildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Bice Salts of Anura

open access: yesChemical and Pharmaceutical Bulletin, 1973
Bile salts of six different species of the Anura were investigated by means of thin-layer chromatography, gas-liquid chromatography, and mass spectrometry. Bile of Xenopus laevis contained taurine-conjugated and free forms of 3α, 7α, 12α-trihydroxy-5β-cholestanoic acid and 5β-cyprinol sulfate2) as its chief constituents.

Effects of complex soundscapes on the occurrence of Anaxipha pallidula in isolated green spaces in Tokyo

open access: yesWildlife Biology, EarlyView.
Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.
