How did the toad get over the sea to Skye? Tracing the colonisation of Scottish inshore islands by common toads (Bufo bufo) (2021)
Journal Article
(Bufo bufo). Herpetological journal, 31, 204-213. https://doi.org/10.33256/31.4.204213

Processes of island colonisation have long been of interest to biologists. Colonisation events themselves are rarely observed, but the processes involved may be inferred using genetic approaches. We investigated possible means of island colonisation... Read More about How did the toad get over the sea to Skye? Tracing the colonisation of Scottish inshore islands by common toads (Bufo bufo).

Linking effective population size dynamics to phenotypic traits in the common toad (Bufo bufo) (2019)
Journal Article
in the common toad (Bufo bufo). Conservation Genetics, 20, 987-995. https://doi.org/10.1007/s10592-019-01185-1

The effective size of a population (Ne) determines the retention of neutral genetic variation in isolated populations, and is therefore a key parameter in conservation genetics. However, while our knowledge on the genetic properties of endangered pop... Read More about Linking effective population size dynamics to phenotypic traits in the common toad (Bufo bufo).

In human-modified landscapes, little is known about the influence of aquatic habitat types on the demographic structure of residing amphibian populations. In the present paper, we focus on a European flagship urodele species (the great crested newt T...

Soil and forest structure predicts large-scale patterns of occurrence and local abundance of a widespread Amazonian frog (2018)
Journal Article
Ferreira, A., Jehle, R., Stow, A., & Lima, A. (2018). Soil and forest structure predicts large-scale patterns of occurrence and local abundance of a widespread Amazonian frog. PeerJ, https://doi.org/10.7717/peerj.5424

The distribution of biodiversity within the Amazon basin is often structured by sharp environmental boundaries, such as large rivers. The Amazon region is also characterized by subtle environmental clines, but how they might affect the distributions...

Journal Article
(Bufo andrewsi). Frontiers in Zoology, 13(6), https://doi.org/10.1186/s12983-016-0138-0

Background: Environmental variation associated with season length is likely to promote differentiation in lifehistory
traits, but has been little studied in natural populations of ectotherms. We investigated patterns of variation
in egg size, clutc... Read More about Geographic variation in life-history traits : growth season affects age structure, egg size and clutch size in Andrew’s toad (Bufo andrewsi).
