Journal of Morphology, Volume 287, Issue 8, August 2026.The ontogenetic development, innervation, and morphology of the shoulder joint and forelimb muscles were investigated in 11 anuran species. The results reveal largely conserved splitting patterns of the dorsal and ventral pre‐muscle masses, alongside interspecific variation in muscle subdivision and morphology.

Nature Conservation Research: Заповедная наука, 2018 Amphibians are an important but vulnerable component of biodiversity. Climatic changes and anthropogenic transformation of the environment can lead to changes in spawning times and habitat boundaries, causing adverse genetic processes in populations.

Molecular Ecology, Volume 35, Issue 15, August 2026.ABSTRACT Identifying which populations within species to prioritize to maintain genetic diversity is challenging. Due to its direct connection to current patterns of adaptation and presumed connection to adaptive capacity, some researchers advocate prioritizing adaptive variation.

Behavior and mortality of anurans on roads in the Australian tropics
The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.Roads are a major source of mortality for wildlife, particularly amphibians. Identifying vulnerable species and understanding any behavioral predictors of mortality helps us understand vulnerability to traffic and can inform management strategies. We investigated a 9‐species anuran community in tropical Australia with respect to 3 behavioral responses ...

Method for obtaining Chromosomes Method for obtaining Chromosomes
Caldasia, 1973 It is very easy to obtain chromosomes from anuran amphibians.Amphibians have very large chromosomes which can easily be seen with an ordinary microscope. The method used has been tested in the laboratory and also at collecting sites. All that is required

Intoxicação por veneno de sapo em um canino Toad venom intoxication in a dog
Ciência Rural, 2008 O sapo do gênero Bufo possui nas suas glândulas paratóides uma secreção mucóide contendo toxinas como bufaginas e Bufotoxinas, que são esteróides cardiogênicos. Os cães podem atacar os sapos, entrando em contato com o veneno por meio das mucosas.

Conservation Science and Practice, Volume 8, Issue 7, July 2026.We evaluated the impacts of grazing, climatic variability, and vegetation productivity on the population dynamics of a northern Great Plains greater sage‐grouse population. We found winter temperature influenced annual population growth rates, but did not detect influences of drought, breeding season weather, vegetation productivity or short‐term ...

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 ...
