Male body size and parental relatedness but not nuptial colouration influence paternity success during scramble competition in Rana arvalis (2014)
Journal Article
Rausch, A., Sztatecsny, M., Jehle, R., Ringler, E., & Hoedl, W. (2014). Male body size and parental relatedness but not nuptial colouration influence paternity success during scramble competition in Rana arvalis. Behaviour, 151, 1869-1884. https://doi.org/10.1163/1568539X-00003220

Female mate choice promotes the development of male secondary sexual traits such as nuptial colouration, whereas scramble competition favours male traits which enhance their ability for access to females. In the explosively breeding moor frog (Rana a...

Determining whether isolated populations of a species are native or introduced is important for conservation, as non-native occurrences are likely to be of lower priority for conservation organisations with limited resources. The great crested newt T...

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).
