Adrienne Crosier is a biologist with the Smithsonian Conservation Biology Institute (SCBI) and manager of the cheetah reproductive and research program. Crosier's current research program focuses on understanding fundamental carnivore biology to improve reproduction. Specifically, she has an interest in understanding management-based causes of infertility in captive-held carnivores and developing and utilizing assisted reproductive technologies for improved reproduction and offspring production. One of her primary research areas involves improving cheetah management and health for more efficient reproduction.
Working with colleagues from SCBI, the Cheetah Conservation Fund (CCF), the University of California-Davis and veterinary pathologists Linda Munson and Karen Terio, Crosier and the research team were the first to document age related changes to female cheetah physiology. The team determined that although cheetah females develop uterine pathologies as young as 6 years old, which reduces fertility as they age, their oocytes (eggs) remain viable up to 12 years old. These significant findings have guided cheetah management and breeding recommendations in the Species Survival Plan population.
Crosier trained as a postdoctoral fellow with the National Zoological Park in Namibia, based at the Cheetah Conservation Fund (CCF), where she developed a multi-disciplinary approach to addressing cheetah health and reproduction challenges. During her post-doctoral research, Crosier developed cryopreservation protocols for spermatozoa from free-ranging endangered cheetahs, trained local biologists and established a genome resource bank of genetic materials at the CCF. Since 2007, Crosier has been managing the cheetah breeding program at SCBI. The facility has produced 34 cubs in nine litters.
Crosier currently is the head of the Association of Zoos and Aquariums Species Survival Plan Program for Cheetahs, leading the 55 North American cheetah holding facilities in collaborative research and management programs. Adrienne is also involved with the reproductive management of the SCBI black-footed ferret collection, conducting sperm cryopreservation studies and artificial insemination. She recently received the Outstanding Young Alumnus award from North Carolina State University.
