Analysis of organic contaminants in New Zealand marine mammals
1. Chlorinated organic contaminants were analysed in samples of blubber collected from New Zealand's Hector's dolphin (Cephalorhynchus hectori ) and dusky dolphins (Lagenorhynchus obscurus ). 2. Polychlorinated biphenyl (PCB) congeners were detected in all samples analysed. Total PCB concentrations measured in these samples were lower than those detected in cetaceans from other countries. 3. Po...
متن کاملBrucellosis in Endangered Hector's Dolphins (Cephalorhynchus hectori).
Brucella spp infections of marine mammals are often asymptomatic but have been associated with reproductive losses and deaths. Zoonotic infections originating from marine isolates have also been described. Hector's dolphins (Cephalorhynchus hectori) are an endangered species with a declining population, and the role of infectious disease in population dynamics is not fully understood. In this s...

متن کاملFeeding at a high pitch: source parameters of narrow band, high-frequency clicks from echolocating off-shore hourglass dolphins and coastal Hector's dolphins.
Toothed whales depend on echolocation for orientation and prey localization, and source parameters of echolocation clicks from free-ranging animals therefore convey valuable information about the acoustic physiology and behavioral ecology of the recorded species. Recordings of wild hourglass (Lagenorhynchus cruciger) and Hector's dolphins (Cephalorhynchus hectori) were made in the Drake Passage...
متن کاملAn Application of Close Range Photogrammetry in Dolphin Studies
Dolphins are agile animals and are very difficult to measure at sea. However, for the conservation of threatened or endangered species, measurement may be vital because it allows a demographic analysis of the population. Hector’s dolphin (Cephalorhynchus hectori) is a rare species living only in coastal waters around New Zealand where it is studied from small boats. This paper describes a stere...
