My dissertation research focused on the behavior, movement patterns, and foraging ecology of dusky dolphins (Lagenorhynchus obscurus) off the east coast of New Zealand's South Island. Information on growth, morphometrics, parasites and life history was also collected. Movement patterns and foraging behavior of New Zealand dusky dolphins were much different from those of dusky dolphins observed off the Argentine coast by Bernd Wursig, the only other study of dusky dolphin behavior. Unlike the Argentine dolphins, which cooperatively herd anchovy to the surface and contain them there for feeding, New Zealand dusky dolphins behave and forage more like Hawaiian spinner dolphins (Stenella longirostris). In summer and fall, New Zealand dusky dolphins remain near shore in morning and early afternoon hours, then move into deeper water with greatly increased activity levels in late afternoon. In winter and spring they remain farther from shore at all times of day, are found in somewhat larger groups, and appear to travel along shore more often than in other seasons. In summer, dive times of radio-tagged dolphins also varied on a daily cycle, most long dives occurring during crepuscular and night periods. Stomach contents of incidentally-netted and beachcast dolphins contained primarily a demersal fish and a few types of mesopelagic fishes and squid. Acoustic surveys along the east coast of South Island show a dense layer of mesopelagic fishes and squid that move to within 50-100 m of the surface at night. Like Hawaiian spinners, New Zealand dusky dolphins feed primarily on prey in and associated with the vertically migrating layer, probably as a means of increasing foraging efficiency. External measurements of L. obscurus specimens were analyzed using canonical variate analysis, which revealed measurements useful in discrimination of age/sex classes, including dorsal fin dimensions, and positioning of dorsal fin and flipper insertions. Tooth-section age analysis of specimens allowed construction of growth curves; life span maximum was about 35 years. The very large size of active testes (over 1 kg each) during summer breeding represents a large proportion of total body weight. Along with observations of group composition variability, this suggests a promiscuous mating system and a fluid, extended-group social system.

Transparencies: New Zealand from 1953 to 1974 through the Slide Photography of Gladys Cunningham This thesis focuses on the amateur slide photography of Gladys Cunningham, formerly of Onehunga, Auckland. Viewed collectively, these slides provide a visual autobiography of a New Zealand woman’s life, as well as a larger social narrative. As Gladys’s granddaughter, I argue that Gladys’s 35mm colour transparencies, nostalgic fragments that memorialise a family history, are informed by the social history of European New Zealanders between the early 1950s and early 1970s. Gladys’s slides reflect stabilities and changes for the photographer herself, her family and New Zealand society. While the term “transparency” suggests that the meaning of a slide can be understood by all, in reality further contextual information is necessary to appreciate the family and public histories from which these scenes have been separated. To situate Gladys’s slides, I refer to popular magazines and tourist texts from this period, including The Weekly News, National Geographic and New Zealand Holiday, and to commercial slides, postcards and travel marketing texts. I analyse the near absence of Maori within Gladys’s slides and travel journalism, suggesting that their omissions represent a lack of dialogue between Pakeha and Maori. In New Zealand and overseas, slide photography was the popular medium for recording extraordinary family events during the 1950 and 1960s. Through an analysis of memory, leisure and photography, this study examines how Gladys’s photography documents family and community membership and celebration. I explore how aesthetically pleasing representations of family leisure also contain partly concealed clues to less positive memories and to secrets that were not unique to this family. I discuss the impact of private and public transport on Gladys’s slide photography, noting how car travel facilitated spatial and temporal freedoms, and how slide photography strengthened connections to extended family and distant communities. In contrast, Gladys and Jim’s later dependence on coach transport enhanced their ability to take slides and expanded the “family” gaze of their camera, but limited their photographic opportunities.
