Our new article how sex roles shape androgen and hematocrit profiles (or the other way round?) of classically polyandrous red phalaropes and polygynous pectoral sandpipers

Sex differences in testosterone and hematocrit levels reflect mating system differences of two Arctic-breeding shorebird species
Differences in mating strategies are often accompanied by differences in physiology. In two species of shorebirds, we found that testosterone levels reflec

Wie beeinflusst Angst das Kampfverhalten von Fischweibchen? 🐟⚔️😨
Salustri et al. untersuchten, ob Alarmstoffe (AS) die Aggression weiblicher Zebrafische in aufeinanderfolgenden Begegnungen verändern. AS senkten die Motivation, sich auf Kämpfe einzulassen – doch aggressives Verhalten blieb bestehen!

🧪 ETHOLOGY: How does fear shape female fish fights? 🐟⚔️😨
Salustri et al. tested whether alarm substances (AS) alter aggression in female zebrafish across encounters. AS reduced motivation to engage, but aggressive behavior was still maintained! Read more: doi.org/10.1111/eth.... #FishBehaviour
Agonistic Behavior and Fear Response During Consecutive Encounters in Female Fish
A well-established paradigm to assess different aspects related to fear sensing is the exposure to alarm substances (AS) from conspecifics in fish. While consecutive agonistic encounters modulating a...

Forschung zu Vogelgesang fokussiert oft weibliche Präferenzen — aber was mögen Männchen an weiblichen Lauten? 🐦🎶❤️
Le Gal et al. testeten männliche Kanarienvögel mit weiblichen Kopulations-Trillern. Es zeigte sich keine Gruppenpräferenz, aber einzelne Männchen hatten klare individuelle Vorlieben!

Risikoverhalten abhängig vom Zustand bei Mäusen! 🐭💥🍔
Lopez-Hervas et al. zeigen, dass Futterqualität und Körpermasse die Reaktionen von Mäusen auf Gefahr beeinflussen — schwerere, oder Tiere mit besseren Ressourcen, verhalten sich vorsichtiger und stützen damit die Asset-Protection-Hypothese!

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.
