The clockwork of insect activity: Advancing ecological understanding through automation

open access: yesJournal of Animal Ecology, Volume 94, Issue 4, Page 597-610, April 2025.
The study demonstrates that time‐controlled insect sampling using an automated Malaise trap in combination with metabarcoding allows for the observation and documentation of taxon‐specific activity patterns. These recorded activity patterns can provide valuable insights into the underlying ecological processes, including parasitoid–host relationships ...

Molecular Clock Dating using MrBayes [PDF]

open access: yesarXiv, 2016
This paper provides an overview and a tutorial of molecular clock dating using MrBayes, which is a software for Bayesian inference of phylogeny. Two modern approaches, total-evidence dating and node dating, are demonstrated using a dataset of Hymenoptera with molecular sequences and morphological characters.
