Congratulations to Holly Hennin for having her third PhD thesis chapter accepted in Ecology and Evolution. Entitled “Baseline glucocorticoids are drivers of body mass gain in a diving seabird“, the paper uses an experimental approach to examine the causal links between elevated baseline corticosterone and fattening in captive white-winged scoters. Holly’s results show that elevated baseline corticosterone can have a positive effect on fattening without inhibiting the Hypothalamic-Pituitary-Adrenal (HPA) axis. Fantastic work Holly!
