Abstract:

The small group of Canis lupus on Isle Royale, Michigan, has been studied for over 30 yr. During the last 10 yr the population declined from 50 individuals to as few as 12 individuals. The authors address the issues of genetic variability and relationships of these wolves using allozyme electrophoresis, mtDNA restriction-site analysis, and multilocus hypervariable minisatellite DNA analysis (genetic fingerprinting). Some 50% of the allozyme heterozygosity has been lost in the island population, a decline similar to that expected if no immigration had occurred from the mainland. The wolves have an mtDNA genotype that is very rare on the mainland, suggesting that the remaining Isle Royale wolves are probably derived from a single female founder.
