Verborgene Rhythmen im Cichliden-Alltag — Holtz et al. nutzen Computer-Vision-Analyse, um feine Unterschiede in Bewegungsmustern bei Buntbarschen aus dem Malawisee aufzudecken. Solche Nischenaufteilung im Verhalten kann zur Artenvielfalt beitragen, jenseits von Nahrungsunterschieden. 🐟📹🤖 #Ethologie

Wie wirken sich Mikroplastikpartikel auf das Gehirn von Fischen aus? 🧠🐟
Lucon-Xiccato et al. testeten, ob synthetisches (PE) oder biologisch abbaubares (PBAT) Mikroplastik die Kognition von Zebrafischen beeinflusst. PE senkte deutlich die Gehirnaktivität – das Lernvermögen blieb jedoch unverändert.
