Productive days in České Budějovice with @jiri-tuma.bsky.social and @eliaguariento.bsky.social, focusing on all aspects of camera traps for the MonitAnt project. We even squeezed in a wonderful trip to Šumava National Park.

Evidence for climate-mediated range expansion of hybrid wood ants Climate change challenges many species. To persist, species can shift ranges, respond plastically, and adapt. Yet, these responses require variation - often limited in natural populations. While hybri...

Exciting MonitAnt meeting at the Natural History Museum, Brussels. Great discussions on fieldwork and ant ID, plus a rare glimpse of the museum after hours! 🐜🦖

One mother for two species via obligate cross-species cloning in ants - Nature In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same mother having distinct genomes and morphologies.

This work comes out of the excellent master thesis of Felix Puff at the University of Vienna, also under the supervision of Christian Schulze.
During fieldwork Felix discovered also the northernmost occurrence of Tritemis annulata:
