Locomotor, ecological and phylogenetic drivers of skeletal proportions in frogs. [PDF]
J Anat, 2023 Frogs exhibit complex anatomical features of the pelvis, limbs and spine, long assumed to represent specialisations for jumping. Yet frogs employ a wide range of locomotor modes, with several taxa featuring primary locomotor modes other than jumping ...

Digital dissection of the head of the frogs Calyptocephalella gayi and Leptodactylus pentadactylus with emphasis on the feeding apparatus. [PDF]
J Anat, 2021 Our study presents MicroCT‐scans of two frog species in order to reconstruct the complete anatomical condition of the whole feeding apparatus for the first time. The figure depicts a sagittal section through the heads of Calyptocephalella gayi (A) and Leptodactylus pentadactylus (B). Abstract Micro‐computed tomography (microCT) of small animals has led

First fossil frog from Antarctica: implications for Eocene high latitude climate conditions and Gondwanan cosmopolitanism of Australobatrachia. [PDF]
Sci Rep, 2020 Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone that can be attributed to the Recent,

Quantifying exposure of amphibian species to heat waves, cold spells, and droughts. [PDF]
Conserv BiolAbstract Globally, amphibians face severe threats, such as climate change and associated extreme events. Our goal was to quantify global amphibian exposure to 3 classes of extreme events: heat waves, cold spells, and droughts. We used the MERRA‐2 extreme climate events data and the standardized precipitation–evapotranspiration index database to ...
