Bergmann ecogeographic trends among triplefin blennies (Teleostei: Tripterygiidae) in the Gulf of California, Mexico

  • Matthew R. Gilligan
Brief communication


Bergmann-type ecogeographic patterns are common among small resident rocky-shore fishes in the Gulf of California where triplefin blennies (Tripterygiidae) represent a significant component of the community. Using estimates of adult body size from samples throughout the Gulf, four triplefin species, three more than previously reported, showed significant correlations of body size with latitude. The intensity and form of the relationships are given. Measuring the length of the largest individual in samples rather than using average body weight per individuals in samples offers a better estimate of adult body size.
