Journal Article
Jiang, A., Zhong, M., Xie, M., Lou, S., Yin, L., Jehle, R., & Liao, W. (2015). Seasonality and age is positively related to brain size in Andrew’s toad (Bufo andrewsi). Evolutionary Biology, 42(3), 339-348. https://doi.org/10.1007/s11692-015-9329-4

The Expensive Brain Framework (EBF) and the Cognitive Buffer Hypothesis are commonly used to explain inter- and intraspecific variation in brain size and brain architecture. Using Andrew’s toad (Bufo andrewsi) as a model species, we investigated whet... Read More about Seasonality and age is positively related to brain size in Andrew’s toad (Bufo andrewsi).

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...

Evolution of sperm morphology in anurans : Insights into the roles of mating system and spawning location (2014)
Journal Article

Background: The degree of postcopulatory sexual selection, comprising variable degrees of sperm competition and cryptic female choice, is an important evolutionary
force to influence sperm form and function. Here we investigated the effects of
mati... Read More about Evolution of sperm morphology in anurans : Insights into the roles of mating system and spawning location.

Altitudinal variation in maternal investment and trade-offs between egg size and clutch size in the Andrew's toad (2014)
Journal Article

Environmental variation along altitudinal gradients can promote life-history trait differentiation in ectothermic animals. Life-history theory predicts that increased environmental stress results in a shift in reproductive allocation from offspring q...

Farewell to the bottle trap? An evaluation of aquatic funnel traps for great crested newt surveys (Triturus cristatus) (2013)
Journal Article
funnel traps for great crested newt surveys (Triturus cristatus). Herpetological journal, 23(4), 241-244

Aquatic funnel traps are an established technique for the capture of newts. In the United Kingdom they are widely used for commercial surveys of great crested newts (Triturus cristatus) to comply with EU regulations during land developments such as c...

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...

Sexual size dimorphism in anurans fails to obey Rensch’s rule (2013)
Journal Article
Rensch’s rule. Frontiers in Zoology, 10(10), https://doi.org/10.1186/1742-9994-10-10

Background: Sexual size dimorphism (SSD) is related to ecology, behaviour and life history of organisms. Rensch’s
rule states that SSD increases with overall body size in species where males are the larger sex, while decreasing
with body size when... Read More about Sexual size dimorphism in anurans fails to obey Rensch’s rule.

Assessing Risk and Guidance on Monitoring ofBatrachochytrium dendrobatidisin Europe through Identification of Taxonomic Selectivity of Infection (2013)
Journal Article

Amphibians are globally threatened, but not all species are affected equally by different threatening processes. This is true for the threat posed by the chytridiomycete fungus (Batrachochytrium dendrobatidis). We compiled a European data set for B....

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 (2011)
Journal Article

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...
