Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Longevity and survival curves of Rhinella icterica (Anura, Bufonidae) under laboratory conditions

Brazilian Journal of Biology
Life tables and survival curves of tadpoles from Rhinella icterica species were studied in the laboratory, under abiotic conditions controlled by a purification filter, a timer and a chiller. The survival curve for larval stage confirms a great mortality

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

The Tadpoles of Hyla rufitela (Anura: Hylidae)

Revista de Biología Tropical, 2005
The validity of the published description of Hyla rufitela is questioned because the origin of the described tadpoles does not correspond to the distribution of this species.

First genomic analysis of Platycopioida and phylogenomics across six copepod orders

Cladistics, EarlyView.
Abstract Recent advances in bioinformatics have significantly expanded our understanding of the genetic properties of organisms and have provided valuable insights into their phylogenetic relationships and evolutionary histories. However, molecular phylogenetic studies of the class Copepoda remain limited, and the focus has been mainly on the major ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Larval Adaptation to Salinity Shock in Cane Toads (Rhinella marina) From Coastal French Guiana

Ecology and Evolution
Many habitats not only differ in mean conditions but also in the degree to which these conditions fluctuate through time. Therefore, local adaptation to both mean abiotic conditions and habitat variability can enhance organismal viability.

Prolactin and Tadpole Growth.

Experimental Biology and Medicine, 1967
SummaryMammalian prolactin inhibits thyroxin-induced resorption of the tail in Rana catesbeiana tadpoles. Mammalian growth hormone does not show this effect. The possible importance of prolactin as a larval growth hormone in amphibians is emphasized.
