| Summary: | "winter'' and "summer'' groups are temporally and a population expansion in the Pleistocene; (2) current activities after the first hour spent sampling. analysis of 40 "winter'' and 40 "summer'' individuals analysis of photo-identification data indicate analysis suggest New Zealand dusky dolphins underwent Behavioral responses to sampling were recorded for 315 behavioral state of dolphins prior to sampling or time behaviorally segregated into genetically distinct contact joyriders and sample time were used as contacts and 48 controls. The number of pro- and pest- distribution, and coloration patterns of dusky diversity were 0.16 and 0.98, respectively.
