Auditory monitoring of anuran populations

TL;DR: This chapter describes approaches for monitoring anuran populations based solely on auditory techniques, including manual calling surveys, automated recording systems (ARS), or some combination of the two, and explains how data resulting from ARS can be used to optimize manual survey protocol and to interpretData resulting from MCS.

Invasive Plant and Experimental Venue Affect Tadpole Performance

TL;DR: The results suggest that the impact of L. salicaria on ecosystem processes and aquatic food webs may be more general and likely to negatively affect other wetland species.

The Effects of Ultraviolet Radiation on the Biology of Amphibians

TL;DR: Studies including laboratory and field approaches on damage to amphibians from UVB exposure are reviewed and areas of future research are suggested to test the hypothesis of the causal connection between current UVB levels and amphibian decline.

An Electrophoretic Analysis of Holarctic Hylid Frog Evolution

S. Blair Hedges
- 01 Mar 1986 - 
TL;DR: Calibration of the molecular clock for Holarctic hylid frogs suggests that Pseudacris diverged from a Hyla-like ancestor in the early Tertiary, and physiological traits associated with cold-weather breeding and the morphological trait associated with terrestrial habits appear to have been key innovations.

Evolutionary history of the hybridogenetic hybrid frog Rana esculenta as deduced from mtDNA analyses.

TL;DR: The preponderance of R. esculenta individuals with lessonae mtDNA in samples from central Europe suggests that most lineages have gone through at least one mating between an R.Esculenta females with R. lessonae males, and reveals a greater reproductive role for R. Esculenta males than their partial sterility and infrequent matings would suggest.
