This study uses integrated eDNA and SNP analyses to reveal geographic differentiation and hybridization in Odontobutis gobies, showing hybrid origin of O. hikimius.

This study uses gut content and environmental DNA metabarcoding to assess the feeding ecology and ecological risks of the invasive Korean perch in Japan.

This study shows that tadpoles of Dryophytes leopardus develop predator-induced tail coloration in response to specific dragonfly nymphs, with differences in response based on predator foraging behavior and visual capabilities.

This study demonstrates that eDNA analysis can accurately reconstruct phylogeographic patterns of multiple fish species from water samples, reducing the effort required for traditional phylogeographic surveys.
