Immunoendocrinology and Ecoimmunology in Brazilian Anurans

open access: yesIntegrative And Comparative Biology, 2022
Abstract This paper reviews several aspects of immunoendocrinology and ecoimmunology in Brazilian species of anurans under investigation for more than a decade, including (1) patterns of annual covariation of circulating steroids, calling behavior and innate immunity, (2) endocrine and immune correlates of calling performance, (3 ...

From Gondwana to the Yellow Sea, evolutionary diversifications of true toads Bufo sp. in the Eastern Palearctic and a revisit of species boundaries for Asian lineages

open access: yeseLife, 2022
Taxa with vast distribution ranges often display unresolved phylogeographic structures and unclear taxonomic boundaries resulting in hidden diversity.

Watson-Crick conjugates of words and languages [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
In this work, we explore the concept of Watson-Crick conjugates, also known as $θ$-conjugates (where $θ$ is an antimorphic involution), of words and languages.

Reproductive activity of anurans in a dominant agricultural landscape from central-eastern Argentina

open access: yesRevista Mexicana de Biodiversidad, 2013
Agriculture can modify natural systems through habitat loss and fragmentation, as well as through the effect of agrochemicals on biological traits such as reproduction.

Development and characterization of novel microsatellite loci in the native tree frog species, Polypedates braueri and cross-species amplification in the alien species, P. megacephalus, in Taiwan [PDF]

open access: yesBiodiversity Data Journal
Polypedates megacephalus is an alien species first recorded in 2006 in Taiwan. The expanding population of P. megacephalus poses potential threats to the native frog species, especially to the closely-related species P. braueri.

Delineating the anuran axial skeleton

open access: yesThe International Journal of Developmental Biology, 2021
The axial skeleton of the anurans has undergone an evolutionary reduction of its bone elements. This structural plan is strongly preserved throughout the order and would have emerged as a highly specialized anatomical adaptation to its locomotor jumping pattern.

The relationship between pond habitat depth and functional tadpole diversity in an agricultural landscape [PDF]

open access: yesRoyal Society Open Science, 2015
One of the most important goals of biodiversity studies is to identify which characteristics of local habitats act as filters that determine the diversity of functional traits along environmental gradients. In this study, we investigated the relationship

Physiological Control of Water Exchange in Anurans [PDF]

open access: yesEcology and Evolution, 2022
1. Research on water exchange in frogs has historically assumed that blood osmotic potential drives water exchange between a frog and its environment, but here we show that the “seat patch” (the primary site of water exchange in many anurans), or other sites of cutaneous water uptake, act as an anatomic “compartment” with a water potential controlled ...
