Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

A Short‐Read Amplicon Sequencing Protocol and Bioinformatic Pipeline for Ecological Surveillance of Dipteran Disease Vectors

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Vector control remains an important strategy worldwide to prevent human infection with pathogens transmitted by arthropods. Vector control strategies rely on accurate identification of vector taxa along with vector‐specific biological indicators such as feeding ecology, infection prevalence and insecticide resistance.
