Dr. Ulyesses Seal is Chairman of the Conservation Breeding Specialist Group (CBSG), one of more than 100 specialist groups of the Species Survival Commission (SSC) of the World Conservation Union (IUCN), a position he has held since 1979. A biochemist by training, Dr. Seal spent the majority of his professional career as a scientist carrying out research in endocrinology at the Veteran's Administration Center at the University of Minneapolis, Minnesota. He has published more than 260 peer-reviewed articles in scientific journals and about 70 book chapters and reviews. In 1974, he founded ISIS, the International Species Information System, that provides a computerized database for the management of animal collections presently used by more that 450 cooperating zoological institutions worldwide. In 1983, he initiated the first coordinated breeding program, the Tiger SSP, in North America, which soon became the model for coordinated breeding programs now in existence in practically all zoo-regions of the world. Under his leadership, CBSG has become one of the largest and most active specialist groups of IUCN. Over the past ten years, CBSG has developed a number of efficient tools to support and to improve small population management, such as Conservation Assessment Management Plans (CAMPs), Population and Habitat Viability Analyses (PHVAs), Global Captive Breeding Recommendations (GCARs), and Global Animal Survival Plans (GASPs).
