"Assessment of a noninvasive approach to pregnancy diagnosis in gray whales through drone-based photogrammetry and faecal hormone analysis" Fernandez Ajó, A., Pirotta E., Bierlich, K.C., Hildebrand, L., Bird, C.N., Hunt K.E., Buck C.L., New L., Dillon D., Torres, L.G. Keywords: gray whale, progesterone, body width, enzyme immunoassay, pregnancy Author for correspondence ([e-mail]). Geospatial Ecology of Marine Megafauna Lab, Marine Mammal Institute, Department of Fisheries, Wildlife, and Conservation Sciences, Oregon State University, Newport (97365), Oregon, USA Summary Knowledge of baleen whales’ reproductive physiology is limited and requires long-term individual-based studies and innovative tools. We utilized six-years of individual-level data on the Pacific Coast Feeding Group gray whales to evaluate the utility of faecal progesterone immunoassays and drone-based photogrammetry for pregnancy diagnosis. We explored the variability in faecal progesterone metabolites and body morphology ...
