Mitochondrial Phylogenomics and Genome Evolution in Anura: Insights From Structure and Gene Order Rearrangements. [PDF]

Ecol Evol
By 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.

Phenotypic and Ecological Correlates of Population Decline in the World's Anurans. [PDF]

Ecol Evol
In this study, we assess the ecological and environmental factors associated with population decline in the world's anurans, taking into account their evolutionary relationships. A large majority of evaluated species were in decline. Range size and temperature annual range were negatively correlated with decline, whereas latitude was positively ...
