Quantifying exposure of amphibian species to heat waves, cold spells, and droughts. [PDF]

open access: yesConserv Biol
Abstract 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 ...

Cytogenetics and sperm ultrastructure of Atelopus spumarius (Anura, Bufonidae) from the Brazilian Amazon [PDF]

open access: yes, 2013
The current taxonomy of most Atelopus species is based on morphological and color data only. Recent studies suggest that A. spumarius may represent a species complex assigned under the same name.

Kin discrimination in cannibalistic tadpoles of the Green Poison Frog, Dendrobates auratus (Anura, Dendrobatidae) [PDF]

open access: yesPhyllomedusa: Journal of Herpetology, 2009
Cannibalizing a related individual can reduce the inclusive fitness of the cannibal. Hence, mechanisms that allow a tadpole to recognize and modify its behavior toward kin may reduce the inclusive fitness costs of cannibalism.

Conservation of Glomerular Organization in the Main Olfactory Bulb of Anuran Larvae

open access: yesFrontiers in Neuroanatomy, 2020
The glomerular array in the olfactory bulb of many vertebrates is segregated into molecularly and anatomically distinct clusters linked to different olfactory functions. In anurans, glomerular clustering is so far only described in Xenopus laevis.

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]

open access: yes, 2015
Amphibian declines and extinctions are emblematic for the current sixth mass extinction event. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans ...

Morphological comparison of five species of poison dart frogs of the genus Ranitomeya (Anura: Dendrobatidae) including the skeleton, the muscle system and inner organs. [PDF]

open access: yesPLoS ONE, 2017
The morphology of larvae stages of most amphibians are often completely different than in adults. Tadpole descriptions have historically been based on external characters like morphometrics, color pattern and oral disc structure.
