Genetic and migratory evidence for sympatric spawning of tropical pacific eels from Vanuatu (2015)
Journal Article
Schabetsberger, R., Økland, F., Kalfatak, D., Sichrowsky, U., Tambets, M., Aarestrup, K., …Quarterly, G. (2015). Genetic and migratory evidence for sympatric spawning of tropical pacific eels from Vanuatu. Marine Ecology Progress Series, 521, 171-187. https://doi.org/10.3354/meps11138

The spawning areas of tropical anguillid eels in the South Pacific are poorly known, and more information about their life histories is needed to facilitate conservation. We genetically characterized 83 out of 84 eels caught on Gaua Island (Vanuatu)... Read More about Genetic and migratory evidence for sympatric spawning of tropical pacific eels from Vanuatu.

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...

The use of genetic markers to reveal dynamic processes in a common toad (Bufo Bufo) population (2013)
Thesis
Coles, R. The use of genetic markers to reveal dynamic processes in a common toad (Bufo Bufo) population. (Thesis). University of Salford

In contrast to birds and mammals for example, amphibian population studies only rarely capture information based on genealogical relationships among individuals. As a consequence, we only have very limited knowledge about individual fitness measures...

A positive relationship between ant biodiversity (Hymenoptera: Formicidae) and rate of scavenger-mediated nutrient redistribution along a disturbance gradient in a south-east Asian rain forest. Myrmecological news, 14, 5-12

Human modification of pristine habitats almost always leads to the local extinction of a subset of the species present. This means that the ecosystem processes carried out by the remaining species may change. It is well documented that particular spe...
