Analysis of growth and stable isotopes in teeth of male Australian fur seals reveals interannual variability in prey resources

Knox, Travis C; Stuart-Williams, Hilary; Warneke, Robert M; Hoskins , Andrew J; Arnould, John P Y


To detect and monitor long-term ecosystem responses to environmental variability, managers must utilize reliable and quantitative techniques to predict future ecosystem responses. Canine teeth from 67 male Australian fur seals (aged 2-19 yr), collected at Seal Rocks, between 1967 and 1976, were measured for relative growth within the dentine growth layer groups (GLGs), as an index of body growth. Fluctuations in relative growth were apparent during 1956-1971, suggesting interannual variation in...[Show more]
