Shift of Nitrogen and Carbon Stable Isotopes in Temporary Pond Tadpoles Following the Decline of Large Mammalian Herbivores. [PDF]
Ecol EvolOur study investigates how the decline of large mammalian herbivores in Comoé National Park, Ivory Coast, influenced nutrient dynamics in temporary ponds. Using stable isotope analyses of tadpoles collected before (1995–1996) and after (2014–2019) the decline, we reveal a consistent decrease in δ15N values across multiple taxa, suggesting a system‐wide

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.

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene-Edited Xenopus Tadpoles. [PDF]
J Pineal ResABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Locomotor, ecological and phylogenetic drivers of skeletal proportions in frogs. [PDF]
J Anat, 2023 This study investigates the link between skeletal anatomy and locomotor mode, habitat type and evolution in frogs, shedding new light on how functional demands impact morphology. Sacral expansion is the strongest driver of morphological variation. Locomotor mode has a more significant impact on morphology than habitat type and phylogenetic history ...

Pleistocene Forest Stability Predicts Patterns of Frog Diversity in Central Africa. [PDF]
Ecol EvolUsing high‐resolution paleoclimate reconstructions, we quantified habitat stability for Central African rainforests across 257 time slices since the early Pleistocene. Stacked projections of forest‐dependent frog niches identify both a large, continuous refugium and smaller, highly stable forest blocks embedded within today's forest cover.
