Sampling design may obscure species–area relationships in landscape-scale field studies [PDF]
, 2020 We investigated 1) the role of area per se in explaining anuran species richness on reservoir forest islands, after controlling for several confounding factors.

Geographic Variation in Organ Size in a Toad (Duttaphrynus melanostictus)
Animals, 2023 Adaptive evolution is the process by which organisms change their morphological, physiological and biochemical characteristics to adapt to different environments during long-term natural selection.

Testing the Role of Natural and Sexual Selection on Testes Size Asymmetry in Anurans
Biology, 2023 Directional asymmetry in testes size is commonly documented in vertebrates. The degree of testes size asymmetry has been confirmed to be associated with natural and sexual selection. However, the role of natural and sexual selection driving variations in

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]
, 2016 Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.

Delineating the anuran axial skeleton
The International Journal of Developmental Biology, 2021 The axial skeleton of the anurans has undergone an evolutionary reduction of its bone elements. This structural plan is strongly preserved throughout the order and would have emerged as a highly specialized anatomical adaptation to its locomotor jumping pattern.

Diversity, 2022 Wetland mitigation efforts have increased in numbers over the past two decades to combat wetland loss in the United States. Data regarding wetland function such as biodiversity are required to be collected 5–10 years after a project is complete; however,

Evolutionary insights into umami, sweet, and bitter taste receptors in amphibians
Ecology and Evolution, 2021 Umami and sweet sensations provide animals with important dietary information for detecting and consuming nutrients, whereas bitter sensation helps animals avoid potentially toxic or harmful substances. Enormous progress has been made toward animal sweet/

Digital dissection of the model organism Xenopus laevis using contrast-enhanced computed tomography [PDF]
, 2017 The African clawed frog, Xenopus laevis, is one of the most widely used model organisms in biological research. However, the most recent anatomical description of X. laevis was produced nearly a century ago.

CHORUSING PATTERNS OF A DIVERSE ANURAN COMMUNITY, WITH AN EMPHASIS ON SOUTHERN CRAWFISH FROGS (LITHOBATES AREOLATUS AREOLATUS) [PDF]
, 2016 Wildlife surveys have a critical role in conservation efforts and the collection of life history data. For anuran amphibians these surveys often focus on calling males.
