Morphological differentiation of the common toad Bufo bufo (Linnaeus, 1758) in the central part of the Balkan Peninsula [PDF]

open access: yesArchives of Biological Sciences, 2013
This study analyzes the degree of morphological differentiation among populations of the common toad Bufo bufo in the central part of the Balkan Peninsula. Variations in a number of morphometric and qualitative characters in 14 population samples were

Similar population dynamics before and after a chytridiomycosis outbreak in a tropical riparian amphibian species

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Emerging infectious diseases can cause rapid, widespread host mortality, and the lack of demographic data before and after pathogen emergence complicates understanding mechanisms of host persistence. This challenge is further compounded by environmental conditions that influence host behavior, while driving pathogen growth and virulence. These

Pond frog as a predator of hornet workers: High tolerance to venomous stings

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Some animals use stingers to repel attackers, and some predators have evolved tolerance to such stings, enabling them to consume venomous prey. For example, social wasps, such as hornets, use modified ovipositors as venomous stingers to inject venom, which can cause intense pain in humans.

Heated Aquatic Shelters Reduce Infection Intensity but Not Prevalence of a Fungal Pathogen in Common Toad Tadpoles

open access: yesAnimal Conservation, Volume 28, Issue 6, Page 844-853, December 2025.
In a mesocosm experiment we tested whether heated aquatic shelters would help tadpoles of amphibian populations to eliminate Batrachochytrium dendrobatidis (Bd) infection or reduce its costs. Our results showed that, after appropriate modifications, the shelters could be effectively used in mitigation actions against Bd or other waterborne pathogens ...

Application of Invertebrate‐Derived DNA Barcoding (iDNA) in Blood Sucking Leeches From West Sumatra: A Discovery of Blue‐Eyed Litter Frog Leptobrachium waysapuntiense

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study explores the use of invertebrate‐derived DNA (iDNA) from haematophagous leeches to assess vertebrate biodiversity in the tropical rainforests of Indonesia. By applying Sanger sequencing with five primer sets, we detected 17 unique vertebrate taxa, including the rare Leptobrachium waysepuntiense, demonstrating the potential of iDNA as a ...
