Table 2.
Results of repeated-measures ANOVAs examining predictors of circulating luteinizing hormone or testosterone in male dark-eyed juncos. Hormones were sampled prior to or following injection (time point) in Carolina or white-winged juncos (population). LH was sampled following GnRH challenge, while T was sampled following either LH or GnRH challenge (injection type). Significant predictors are indicated in bold.
