Genetic research is the largest area of effort within ConGen. This program works on genetics issues confronting small, fragmented populations in threatened habitats. Research to ameliorate the threats of inbreeding and loss of genetic variation are important contributions of this program. Another significant area involves an assessment of conservation units, and the use of systematics for establishing conservation priorities. Past examples of this research include a genetic assessment and plan for the St. Vincent Amazon Parrot, St. Vincent and the Grenadines and the selection of release candidates for the black and white ruffed lemur reintroduction program in Madagascar.
