Always a pleasure to see @veronicagroves.bsky.social present research from her PhD at #ICAIS2026. She explored the thermal tolerance response of native species exposed to invasive #Nileperch predator odour in Uganda. @qubelfastofficial.bsky.social. #invasivespecies

Successful @ricciardilab.bsky.social outreach event at one of @picard-m.bsky.social #TubenoseGoby sampling sites. Had fun discussing the importance of #InvasiveSpecies prevention alongside @emmaschubert.bsky.social @vanmierlo.bsky.social @briellecomartin.bsky.social and @ivanakomendic.bsky.social

Tubenose goby (Proterorhinus semilinaris) eggs slowly growing over two weeks. The fry (or “goblets”) should hatch any day now! The father has been diligently nest guarding.
