Different Macroevolutionary Trajectories Lead to Contrasting Ecogeographical Patterns in Two Widespread Frog Radiations

Global Ecology and Biogeography, Volume 34, Issue 8, August 2025.
ABSTRACT Aim Large‐scale evolutionary radiations often occur through marked climatic gradients, which can promote morphological variation. However, opposite trends to the well‐known ecogeographical rules can be observed in closely related clades across different geographic regions.

Pharmacological Effects of Two Novel Bombesin-Like Peptides from the Skin Secretions of Chinese Piebald Odorous Frog (Odorrana schmackeri) and European Edible Frog (Pelophylax kl. esculentus) on Smooth Muscle [PDF]

, 2017
Bombesin-like peptides, which were identified from a diversity of amphibian skin secretions, have been demonstrated to possess several biological functions such as stimulation of smooth muscle contraction and regulation of food intake.

Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco

Environmental DNA, Volume 7, Issue 4, July–August 2025.
ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...

Speciation and zoogeography of amphibian in Sundaland

Journal of Biological Researches, 2015
Sundaland is an interesting area to be explored based on its geological history, topography, and climate. Sundaland consists of Penisular Malaysia, Sumatra, Borneo, and Java which experienced some emergence and submergence process in the past.

Cutaneous shedding in amphibians causes shifts in bacterial microbiomes

Integrative Zoology, Volume 20, Issue 4, Page 807-816, July 2025.
Trends of bacterial load and diversity on cane toad skin suggest that regular shedding events reduce bacterial abundance, consequently also reducing richness and causing a shift in community structure. After reductions due to shedding, bacteria regrow and recolonize until the next shed days later, suggesting that skin communities are constantly in flux,

Interplay of Genotypic and Thermal Effects on Sex Determination Shapes Climatic Distribution in Herpetofauna

Global Ecology and Biogeography, Volume 34, Issue 7, July 2025.
ABSTRACT Aim Sex is a fundamental trait of many organisms, and sex‐determination systems are diverse across the tree of life. Environmental temperature can influence sexual development not only in temperature‐dependent sex‐determination systems, but also in species with genotypic sex determination (GSD). Temperature‐induced sex reversal, resulting from

Foraging niche partitioning within a recently established guild of falcons

Ibis, Volume 167, Issue 3, Page 734-749, July 2025.
Ecological theory predicts that coexisting species should exhibit realized niche differentiation to minimize competition. However, little is known about patterns of niche differentiation when ‘newcomer’ species spontaneously colonize a new region, leading to novel sympatric conditions.
