AFLPs: genetic markers for paternity studies in newts (Triturus vulgaris) (2006)
Journal Article
Jehle, R., Whitlock, A., & Sztatecsny, M. (2006). AFLPs: genetic markers for paternity studies in newts (Triturus vulgaris). Amphibia-Reptilia, 27(1), 126-129. https://doi.org/10.1163/156853806776052029

DNA-based genetic markers can reveal paternity whenever the direct assignment of fathers to offspring is precluded by multiple matings and internal fertilisation. Microsatellites are the current marker of choice in many behavioural studies, and have... Read More about AFLPs: genetic markers for paternity studies in newts (Triturus vulgaris).

Contemporary gene flow and the spatio-temporal genetic structure of subdivided newt populations (Triturus cristatus, T. marmoratus) (2005)
Journal Article
of subdivided newt populations (Triturus cristatus, T. marmoratus). Journal of Evolutionary Biology, 18, 619-628. https://doi.org/10.1111/j.1420-9101.2004.00864.x

Gene flow and drift shape the distribution of neutral genetic diversity in metapopulations, but their local rates are difficult to quantify. To identify gene flow between demes as distinct from individual migration, we present a modified Bayesian...

Delineating fine-scale genetic units in amphibians: probing the primacy of ponds (2005)
Journal Article
probing the primacy of ponds. Conservation Genetics, 6, 227-234. https://doi.org/10.1007/s10592-004-7832-8

The population structure of pond-breeding amphibians is shaped by their distinct breeding foci, but it is unclear to what extent this is reflected in the fine-scale distribution of genetic diversity. We used microsatellite genotypes to investigate... Read More about Delineating fine-scale genetic units in amphibians: probing the primacy of ponds.

Journal Article
model selection approach. Herpetological journal, 14, 89-97

Despite the key role of premetamorphic amphibians in experimental ecology, the factors affecting their abundance has received relatively little attention in natural settings. We applied a model selection approach with AIC (Akaike's Information Crit...

Conservation biology requires the assessment of demographic parameters and life-history data in wildlife populations. Such data can be gathered through capture-mark-recapture (CMR) of individuals. Marking techniques may vary for study organisms, rese... Read More about Cost comparison of marking techniques in long-term population studies: PIT-tags versus pattern maps.
