Competing hypotheses for the etiology of cryptorchidism in Sitka black‐tailed deer: an evaluation of evolutionary alternatives
Abstract On the Aliulik Peninsula (AP) of Kodiak Island, Alaska, 70% of male Sitka black‐tailed deer (SBTD; Odocoileus hemionus sitkensis ) are bilaterally cryptorchid (both testes fail to descend; male is sterile). Both genetic and environmental factors have been proposed as possible causes of this...
