Optimising recovery of DNA from minimally invasive sampling methods: Efficacy of buccal swabs, preservation strategy and DNA extraction approaches for amphibian studies (2024)
Journal Article

Studies in evolution, ecology and conservation are increasingly based on genetic and genomic data. With increased focus on molecular approaches, ethical concerns about destructive or more invasive techniques need to be considered, with a push for min...

Extreme genetic depletion upon postglacial colonization hampers determining the provenance of introduced palmate newt populations (2024)
Journal Article

MtDNA barcoding is regularly applied to determine the provenance of invasive species. Variation in spatial genetic structuring across a species’ range, typically high within glacial refugia and low in postglacially colonized areas, influences the pre...

When backcrosses are fertile, interbreeding between endangered taxa can lead to the admixture of gene pools under threat. One such case pertains to the Mesoamerican crocodile Crocodylus moreletii, a species which shows strong signatures of both recen...

High Evolutionary Potential Maintained in Common Frog (Rana temporaria) Populations Inhabiting Urban Drainage Ponds (2023)
Journal Article

Urbanisation leading to habitat change and fragmentation is a recognised global threat to biodiversity. However, it may also offer opportunities for some species. Genetic diversity, one of the three components of biodiversity, is often overlooked in...

N-mixture models provide informative crocodile (Crocodylus moreletii) abundance estimates in dynamic environments (2022)
Journal Article
Nobrega, J., González-Jaurégui, M., & Jehle, R. (2022). N-mixture models provide informative crocodile (Crocodylus moreletii) abundance estimates in dynamic environments. PeerJ, 10, e12906

Estimates of animal abundance provide essential information for population
ecological studies. However, the recording of individuals in the field can be
challenging, and accurate estimates require analytical techniques which account for
imperfect... Read More about N-mixture models provide informative crocodile (Crocodylus moreletii) abundance estimates in dynamic environments.

Challenging a host–pathogen paradigm: Susceptibility to chytridiomycosis is decoupled from genetic erosion (2022)
Journal Article

The putatively positive association between host genetic diversity and the ability to defend against pathogens has long attracted the attention of evolutionary biologists. Chytridiomycosis, a disease caused by the chytrid fungus Batrachochytrium dend...

Genetic and morphological data demonstrate hybridization and backcrossing in a pair of salamanders at the far end of the speciation continuum (2021)
Journal Article

Deeply diverged yet hybridizing species provide a system to investigate the final stages of the speciation
process. We study a hybridizing pair of salamander species — the morphologically and genetically
drastically different newts Triturus cristat... Read More about Genetic and morphological data demonstrate hybridization and backcrossing in a pair of salamanders at the far end of the speciation continuum.

Reversing a downward trend in threatened peripheral amphibian (Triturus cristatus) populations through interventions combining species, habitat and genetic information (2021)

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).

Thesis
Wagstaff, R. Establishing a protocol to measure tetrodotoxin (TTX) levels in small bodied newts (genus Lissotriton) in western Europe. (Dissertation). University of Salford

Tetrodotoxin (TTX) is a defence toxin most commonly found in marine organisms, and amphibians are the only land vertebrates (tetrapods) which are known to produce TTX. However, the origin of TTX in amphibians remains largely unknown, and our knowledg...
