The influence of environmental variation on the genetic structure of a poison frog distributed across continuous Amazonian rainforest (2020)
Journal Article

Biogeographic barriers such as rivers have been shown to shape spatial patterns of biodiversity in the Amazon basin, yet relatively little is known about the distribution of genetic variation across continuous rainforest. Here, we characterize the ge... Read More about The influence of environmental variation on the genetic structure of a poison frog distributed across continuous Amazonian rainforest.

Stable species boundaries despite ten million years of hybridization in tropical eels (2020)
Journal Article

Genomic evidence is increasingly underpinning that hybridization between taxa is commonplace, challenging our views on the mechanisms that maintain their boundaries.

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).
