Individual recognition of cetaceans: use of photo-identification and other techniques to estimate population parameters

This special issue incorporates the proceedings of a symposium and workshop held in La Jolla, CA, in April-May 1988, beginning with a report of the workshop which records discussion of information presented in the symposium contributions on the subjects of: individual recognition (with a summary of past photo-identification effort on cetacean species); re-identifying individuals; spatial and temporal distributions; estimating population parameters; and recommendations for research. Annexes provide supplementary technical information, including sampling strategies. The 49 published papers range from descriptions of data collection and processing techniques to problems in analysis and calculation of estimates of population parameters. Papers are organized into sections on: field and laboratory methodology; analytical problems (of which 2 are abstracted separately); population parameters, dynamics and behaviour (all 14 abstracted); species case studies (all 15 abstracted); and 4 short photo-identification feasibility studies on other species.
