Top: Blubber testosterone (ng/g lipid mass) concentrations by ordinal date sampled for each demographic group of T. truncatus from Sarasota Bay, FL. Bottom: Unpublished data by R. S. Wells, 2020, frequency of T. truncatus birthdates from 1976–2020 (n = 353) binned in 3-week intervals in Sarasota Bay, FL. The expectation is that testosterone measurements would be the greatest before and near the peak calving period as gestation is estimated to be approximately 12.5 months, and testosterone increases are associated with seasonal testis development54.
