Receptor-mediated endocytosis of lysozyme in renal proximal tubules of the frog Rana temporaria [PDF]

open access: yesEuropean Journal of Histochemistry, 2015
The mechanism of protein reabsorption in the kidney of lower vertebrates remains insufficiently investigated in spite of raising interest to the amphibian and fish kidneys as a useful model for physiological and pathophysiological examinations.

Investigating Sexual Characteristics in Two Frog Species Under Exposure to River Water Polluted with Endocrine Disruptors [PDF]

open access: yesAnimals
Endocrine-disrupting compounds (EDCs) are emerging environmental pollutants that are known to the disrsupt hormonal system of many vertebrates. Amphibians, with their aquatic larval stages and high sensitivity to waterborne contaminants, are especially ...

The Complete Mitochondrial Genome of Nearly Threatened Kwang-Yang Asian Frog <i>Nanorana quadranus</i> (Anura: Dicroglossidae) and Its Phylogenetic Analyses. [PDF]

open access: yesEcol Evol
We report the first complete mitochondrial genome of the near‐threatened frog Nanorana quadranus from the Qinghai‐Tibet Plateau. The 20,173 bp mitogenome includes 13 protein‐coding genes, 21 tRNAs, 2 rRNAs, and a control region. Phylogenetic analysis places N. quadranus in a clade with N.

In-situ Temperature Stations Elucidate Species’ Phenological Responses to Climate in the Alps, but Meteorological and Snow Reanalysis Facilitates Broad Scale and Long-Term Studies

open access: yesFrontiers in Earth Science, 2022
Linking climate variability and change to the phenological response of species is particularly challenging in the context of mountainous terrain. In these environments, elevation and topography lead to a diversity of bioclimatic conditions at fine scales

Local adaptation with high gene flow: temperature parameters drive adaptation to altitude in the common frog (Rana temporaria) [PDF]

open access: yes, 2014
Both environmental and genetic influences can result in phenotypic variation. Quantifying the relative contributions of local adaptation and phenotypic plasticity to phenotypes is key to understanding the effect of environmental variation on populations.
