Until recently, vessel collisions with small cetaceans were presumed rare, mainly as a consequence of limited reporting. Observations on dolphin wound healing from propeller strike injuries also remain scarce. We present an extreme case bottlenose (Tursiops truncatus) multiple wounds, including penetration to the bone, where survival was possible for at least 23 days post injury. used photographic records in conjunction field observations describe progression absence treatment. Considering...

Abstract On a global scale, false killer whales ( Pseudorca crassidens ) remain one of the lesser‐known delphinids. The occurrence, site fidelity, association patterns, and presence/absence foraging in waters off northeastern New Zealand are examined from records collected between 1995 2012. species was rarely encountered; however, 61 distinctive, photo‐identified individuals, 88.5% were resighted, with resightings up to 7 yr after initial identification, movements as far 650 km documented....

Population parameters of poorly marked gregarious species are difficult to estimate. This is the case for common dolphins (Delphinus sp.), a genus known its lack distinctive marks resulting in low mark ratio. Furthermore, widespread nature results recaptures. We developed reliable photo-identification protocols ensure accurate identification individuals Hauraki Gulf, New Zealand. These combined use nicks and notches pigmentation patterns included development distinctiveness threshold. The...

Understanding species distributions, and how they change in space time, is vital when prioritising conservation or management initiatives. We assessed the distribution density patterns of common dolphins (Delphinus sp.), bottlenose (Tursiops truncatus) Bryde's whales (Balaenoptera edeni) Hauraki Gulf, New Zealand. Dedicated boat-based surveys were conducted inner Gulf (IHG) off Great Barrier Island (GBI) during 2010–2012. Generalised linear models used to investigate temporal changes...

Abstract Two ecotypes of the common bottlenose dolphin ( Tursiops truncatus ) occur in New Zealand waters: a widely studied Nationally Endangered coastal ecotype and little‐known oceanic ecotype. Site fidelity association patterns ecotype, home range overlap with are examined from photo‐identification records collected off northeastern between 2005 2016. The occurs study area: distance shore ranged <1 to ~150 km ranges two some areas. Forty‐nine percent 478 identified distinctive or very...
