Integrative Zoology, EarlyView.High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Graellsia, 2002 La posición taxonómica del sapo andino Bufo poeppigii ha sido objeto de controversia desde su descripción por Tschudi en el siglo XIX. Ello se ha debido a su parecido con Bufo marinus y a que ambas especies pueden encontrarse juntas en algunas ...

The Caucasian Toad, Bufo verrucosissimus (Pallas, 1814) in the Levant: evidence from mitochondrial DNA [PDF]
Herpetozoa, 2019 We present the first molecular analysis of the Bufo bufo (Linnaeus, 1758) complex population in the Levant. This complex contains four species distributed through the Western Palearctic.

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians
Integrative Zoology, EarlyView.We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.

Hemoglobin affinity for oxygen in three subspecies of toads (Bufo sp.) living at different altitudes
Biological Research, 2000 Blood oxygen affinity and red blood cell properties were measured in three subspecies of genus Bufo: Bufo spinulosus limensis, collected at sea level and at an average day temperature of 20ºC; Bufo spinulosus trifolium, from 3100 m, average day ...

An Autoradiographic Study of Cell Kinetics in Epidermis of the Toad Bufo bufo bufo (L)
Journal of Investigative Dermatology, 1982 Under normal conditions, the toad Bufo bufo bufo molts about once a week. It was considered of interest to study whether the rhythmic pattern of cell loss through shedding of a stratum corneum is correlated with a rhythmic production of cells in stratum germinativum.

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans
Integrative Zoology, EarlyView.An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

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

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin
Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...
