Calls, colours, shape, and genes: a multi-trait approach to the study of geographic variation in the Amazonian frog allobates femoralis (2009)
Journal Article
frog allobates femoralis. Biological Journal of the Linnean Society, 98(4), 826-838. https://doi.org/10.1111/j.1095-8312.2009.01324.x

Evolutionary divergence in behavioural traits related to mating may represent the initial stage of speciation. Direct
selective forces are usually invoked to explain divergence in mate-recognition traits, often neglecting a role for
neutral process... Read More about Calls, colours, shape, and genes: a multi-trait approach to the study of geographic variation in the Amazonian frog allobates femoralis.

Characterization of microsatellite loci in two closely related Lissotriton newt species (2009)
Journal Article

Care and parentage in a skin-feeding Caecilian amphibian (2008)
Journal Article
amphibian. Journal of Experimental Zoology Part A: Comparative Experimental Biology, 309A, 460-467

An exceptional form of parental care has recently been discovered in a poorly
known caecilian amphibian. Mothers of the Taita Hills (Kenya) endemic Boulengerula taitanus
provide their own skin as a food source for their offspring. Field data sugges... Read More about Care and parentage in a skin-feeding Caecilian amphibian.

Ten polymorphic microsatellite loci for Allobates femoralis, an Amazonian dendrobatoid frog (2008)
Journal Article
an Amazonian dendrobatoid frog. Molecular Ecology Resources, 8, 1326-1328. https://doi.org/10.1111/j.1755-0998.2008.02304.x

Within the anuran amphibians, dendrobatoids (poison-arrow frogs) are renowned for their
parental care, but the lack of highly variable DNA markers so far precluded precise and
comprehensive measurements of their genetic mating system. Here we prese... Read More about Ten polymorphic microsatellite loci for Allobates femoralis, an Amazonian dendrobatoid frog.

Genetic dissimilarity predicts paternity in the smooth newt (Lissotriton vulgaris) (2007)
Journal Article
(Lissotriton vulgaris). Biology Letters, 3, 526-528. https://doi.org/10.1098/rsbl.2007.0311

Under sperm competition, paternity is
apportioned by polyandrous females according
to the order of matings and the genetic quality
of the inseminating males. In order to distinguish
between these two effects, we sequentially
paired 12 female smo... Read More about Genetic dissimilarity predicts paternity in the smooth newt (Lissotriton vulgaris).

Female polyandry under male harassment: the case of the common toad (Bufo bufo) (2006)
Journal Article
common toad (Bufo bufo). Journal of Zoology, 270, 517-522. https://doi.org/10.1111/j.1469-7998.2006.00120.x

Several recent studies have demonstrated the occurrence of multiple paternity in
anuran amphibians, implying that it is more common than previously thought.
However, an adaptive explanation for polyandry in anurans is still lacking. The
common toa... Read More about Female polyandry under male harassment: the case of the common toad (Bufo bufo).

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).

Assessment of 17 new whiskered auklet ( Aethia pygmaea ) microsatellite loci in 42 seabirds identifies 5–15 polymorphic markers for each of nine Alcinae species (2005)

We isolated 17 microsatellite loci in the whiskered auklet (
Aethia pygmaea

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... Read More about Contemporary gene flow and the spatio-temporal genetic structure of subdivided newt populations (Triturus cristatus, T. marmoratus).

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.
