The Complete Mitochondrial Genome of Nearly Threatened Kwang‐Yang Asian Frog Nanorana quadranus (Anura: Dicroglossidae) and Its Phylogenetic Analyses [PDF]
Ecology and EvolutionNanorana quadranus (Liu, Hu & Yang, 1960) is a high‐altitude amphibian species native to the Qinghai‐Tibet Plateau. It plays a vital role in alpine wetland ecosystems and is listed as near threatened (NT) in the IUCN Red List.

Mitochondrial Phylogenomics and Genome Evolution in Anura: Insights From Structure and Gene Order Rearrangements. [PDF]
Ecol EvolBy analyzing 277 anuran mitochondrial genomes, this study reconstructs a robust phylogeny for frogs and toads, tracing their origins to the Triassic and major radiations to the Cretaceous‐Neogene. The research identifies 58 distinct gene arrangement patterns, providing a novel evolutionary framework.

Effects of Predator Species and Size on Prey Escape Success Through the Digestive Tract. [PDF]
Ecol EvolAdults of the aquatic beetle Regimbartia attenuata can survive passage through the digestive tracts of six predator (frog) species, including a non‐native bullfrog. Their active movement through the gut likely facilitates their escape through the cloaca, irrespective of predator species or size.

Seasonal Analysis of the Male Reproductive Tract and Germ Cell Proliferation in Leptodactylus podicipinus (Anura). [PDF]
J MorpholBox 1: Anuran reproductive morphology and dynamics are complex and diverse. Box 2: It is essential to comprehend reproductive morphology in a broad sense and simultaneously at different organizational levels. Box 3: The study characterizes the components of the male reproductive tract and assess testicular cell proliferation throughout the reproductive

Minor Allele Frequency Filtering Can Strongly Bias Uniqueness Estimates Within and Across Species [PDF]
Ecol EvolThis study provides early evidence of minor allele frequency filtering biasing uniqueness estimates. Low filtering thresholds (e.g., 1%) do not necessarily guarantee high reliability. Relatively unique populations can appear to be typical at thresholds of 5% and 10%.

Taxonomic clarifications on the floating frogs (Anura: Dicroglossidae: Occidozyga sensu lato) in southeastern China [PDF]
Vertebrate Zoology, 2022 The recognition for the floating frogs’ genus Occidozyga is in controversy for decades, and the species diversity of these frogs has recently been considered to be underestimated.
