This study evaluates the impact of clustering thresholds on RADseq assemblies in amphibians, showing that topology is resilient to threshold changes but branch lengths are affected.

The paper tracks the movement of a hybrid zone between two marbled newt species using genetic markers and estimates its displacement over time.

The paper examines factors driving population synchrony in great crested newts, finding low synchrony and strong density-dependence across local and continental scales.

The paper examines asymmetric introgression patterns in a toad hybrid zone, identifying shared and transect-specific barrier markers that suggest differences in gene flow restriction between two regions.

The paper resolves the phylogeny of Triturus newts using transcriptome data and shows that NTV count, body form, and aquatic ecology have evolved together.
