Treatment of Lowland Frogs From the Spawn Stage with Homeopathically Prepared Thyroxin (10-30)
The Scientific World Journal, 2007 The influence of a highly diluted agitated, i.e. homeopathically prepared thyroxin solution (10-30, final concentration in the basin water 10-35 parts by weight after the first application) on metamorphosis in lowland Rana temporaria from the spawn stage

Effective Amphibian Conservation Monitoring and Habitat Assessment Using eDNA
Environmental DNA, Volume 7, Issue 5, September–October 2025.ABSTRACT The European green toad (Bufotes viridis) is currently in decline and considered endangered across the northern extent of its native range, with large investments in ongoing conservation and translocation efforts. To assist conservation efforts, survey methods must be established that are cost‐effective, non‐invasive, and rapidly deployable ...

Metamorphosis Reverses the Behavioral Phenotype in Rana arvalis Along a Latitudinal Gradient
Ecology and Evolution, Volume 15, Issue 8, August 2025.Investigating behavior and life history traits in moor frog across a broad latitudinal gradient, we reveal a striking reversal in proactive behavioral tendencies between the tadpole and froglet developmental stages. Furthermore, we demonstrate that the relationship between proactivity and growth rates is shaped by developmental stage, local adaptation,

Host species vary in infection probability, sub-lethal effects, and costs of immune response when exposed to an amphibian parasite [PDF]
, 2015 The amphibian parasite Batrachochytrium dendrobatidis (Bd) is regarded as an extreme generalist, infecting over 500 species, but amongst these hosts there exists a great deal of variation in the susceptibility to and the costs of parasite exposure.

Intra-specific variability and unusual organization of the repetitive units in a satellite DNA from Rana dalmatina: molecular evidence of a new mechanism of DNA repair acting on satellite DNA. [PDF]
, 2006 We have characterized the S1 satellite from eight European populations of Rana dalmatina by Southern blot, cloning and a new method that determines the sequence variability of repetitive units in the genome.
