Spring migration dates of teal Anas crecca ringed in the Camargue, southern France

open access: yesWildlife Biology, Volume 12, Issue 2, Page 163-169, June 2006., 2006
Abstract The policy of the European Commission prohibits hunting of migratory birds while they travel to their breeding grounds. To date, spring migration dates of ducks have mainly been determined using bird counts, but the validity of this sometimes disputed method has never been tested. We used ring‐recovery data from close to 9,000 teal Anas crecca

Baseline reef health surveys at Bangka Island (North Sulawesi, Indonesia) reveal new threats [PDF]

open access: yes, 2016
Worldwide coral reef decline appears to be accompanied by an increase in the spread of hard coral diseases. However, whether this is the result of increased direct and indirect human disturbances and/or an increase in natural stresses remains poorly ...

Whole genome shotgun phylogenomics resolve the diving beetle tree of life

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 940-974, October 2025.
A new and strongly supported phylogeny of diving beetles (Dytiscidae) is presented using the largest genomic dataset to date. Laccophilinae and Coptotominae + Lancetinae are early diverging lineages excluded from a large monophyletic clade comprising the remaining eight subfamilies. We identify seven remaining problems in the backbone of the phylogeny,

Phylogenomic species delimitation of the twisted‐winged parasite genus Stylops (Strepsiptera)

open access: yesSystematic Entomology, Volume 49, Issue 2, Page 294-313, April 2024.
With newly generated whole‐genome sequence data, we use 2315 loci to perform species delimitation analyses for the Strepsiptera genus Stylops in the West Palaearctic region. We infer a minimum of 27 different Stylops species, report 35 new host associations and present justification for 10 synonymizations.
