Congratulations to Graham Sorenson whose first data chapter from his thesis was just accepted to Oecologia! Working with Dr. Cody Dey and Dr. Christine Madliger, Graham performed a meta-analysis to determine whether baseline glucocorticoids reliably predict environmental and fitness-related traits across seabirds. Graham found that while baseline corticosterone may be a useful predictor of larger-scale environmental traits (e.g., food availability) and some fitness-related traits (e.g., reproductive success), it may not be sensitive enough to detect variation in body condition, foraging effort, and breeding effort. This work contributes to our growing understanding of corticosterone as a highly context-dependent hormone, having important implications for its use in ecological and conservation-based monitoring of seabird populations.
