Does the stress axis mediate behavioural flexibility in a social cichlid, Neolamprologus pulcher?

This study investigates how blocking glucocorticoid receptors affects behavioural flexibility in Neolamprologus pulcher fish during predator exposure and detour tasks, finding impaired flexibility and increased fear-related behaviours.

The unexpected loss of the "hunger hormone" ghrelin in true passerines: A game changer in migration physiology

The paper shows that true passerines lost the ghrelin gene but retain its receptor, suggesting a replacement ligand for migratory fat accumulation.

Controlled expression of avian migratory fattening influences innate immune responses

This study shows that migratory birds experience changes in innate immune responses during energy accumulation, with peak immunity occurring mid-fattening and linked to lean mass retention.

Modularity in temporal co-occurrence networks at a stopover site reveals strong co-migration fidelity in African-European migratory landbirds over time

The paper analyzes 15 years of bird ringing data to show increasing co-migration fidelity among African-European migratory landbirds over time, with stronger patterns in trans-Saharan migrants.

Androgen responsiveness to simulated territorial intrusions in Allobates femoralis males: evidence supporting the challenge hypothesis in a territorial frog

The study tests the Challenge Hypothesis in Allobates femoralis frogs by measuring androgen responses to simulated territorial intrusions, finding a positive correlation between intrusions and androgen levels.
