CALL BROADCASTING AND AUTOMATED RECORDERS AS TOOLS FOR ANURAN SURVEYS IN A SUBARCTIC TUNDRA LANDSCAPE [PDF]

open access: diamond, 2014
Relatively little is known about population ecology of anurans in arctic and subarctic tundra regions, in part because it is difficult to survey anurans in these landscapes.

Exploring Brain Size Asymmetry and Its Relationship with Predation Risk Among Chinese Anurans [PDF]

open access: yesBiology
Brain size asymmetry differs considerably across species, including humans, vertebrates, and invertebrates. The subtle structural, functional, or size differences between the two brain sides are associated with processing specific cognitive tasks.

Testing the Role of Environmental Harshness and Sexual Selection in Limb Muscle Mass in Anurans

open access: yesFrontiers in Ecology and Evolution, 2022
Sexual dimorphism is regarded as the consequence of differential responses by males and females to selection pressures. Limb muscle plays a very important role during amplexus, which is likely to be under both natural and sexual selection in anurans ...

PREDATION OF Dryophylax chaquensis (SERPENTES: DIPSADIDAE) UPON Elachistocleis matogrosso AND Boana raniceps (ANURA)

open access: yesActa Biológica Colombiana, 2023
Anurans play a central role in food webs, being prey for different vertebrates, like snakes, mammals, fishes, and birds. The snakes from the tribe Tachymenini are known for their preference for preying on anurans, even different animals eventually being
