Phylogeography of a riparian earthworm shows environmental factors influence genetic structure

Journal of Biogeography, Volume 50, Issue 1, Page 156-168, January 2023., 2023
Abstract Aim The study of cosmopolitan earthworms could be even more interesting than that of endemic species in revealing evolutionary processes. Previous research on the cosmopolitan worm Eiseniella tetraedra has indicated some phylogeographic structure among populations, but the factors responsible remain unresolved.

Unraveling the dietary diversity of Neotropical top predators using scat DNA metabarcoding: A case study on the elusive Giant Otter

Environmental DNA, Volume 3, Issue 5, Page 889-900, September 2021., 2021
A multi‐marker scat DNA metabarcoding approach was used to examine the dietary diversity of the world's largest and rarest otter, the iconic giant otter (Pteronura brasiliensis) from fecal DNA. The combined use of highly discriminant markers (COI and 12S) and of local reference databases of DNA barcodes offered a high accuracy of taxonomic assignments ...
