Adding leaves to the Lepidoptera tree: capturing hundreds of nuclear genes from old museum specimens

open access: yesSystematic Entomology, Volume 46, Issue 3, Page 649-671, July 2021., 2021
A target enrichment kit and workflow to sequence and process hundreds to thousands of loci for recent and old Lepidoptera specimens is presented. Taxa are added to the Lepidoptera phylogeny based on museum specimens collected between 1892 and 2017. Lepidoptera systematic relationships are discussed.

Molecular diet analysis of neotropical bats based on fecal DNA metabarcoding

open access: yesEcology and Evolution, Volume 11, Issue 12, Page 7474-7491, June 2021., 2021
Inferring the exact diets of small, nocturnal mammals such as bats is notoriously difficult. Limited knowledge of what bats actually eat leaves important trophic interactions and food web networks unclear. Using molecular barcoding of plants, vertebrates, and invertebrates, we report fine‐scale dietary detection for 25 species of Belizean bats ...
