Abstract The endemic New Zealand dolphin Cephalorhynchus hectori has been shown through genetic analyses to consist of four regional populations separated to various degrees both geographically and reproductively. A morphological study of skull and mandible features was undertaken to examine variation between the most genetically distinct population, occurring on the west coast of the North Island, and the populations around the South Island. Univariate and principal component analyses… 
Description of a new subspecies of Commerson's dolphin, Cephalorhynchus commersonii (Lacépède, 1804), inhabiting the coastal waters of the Kerguelen Islands
Several arguments, including geographic isolation, morphological difference and genetic data (absence of genetic flow between populations and haplotype differences) lead to formally distinguishing a new subspecies, Cephalorhynchus commersonii kerguelenensis, from a nominate subspecies.
Variation in cranial morphology of bottlenose dolphins (genus Tursiops ) off South Africa
This study aimed to shed light on morphological variation of the genus Tursiops in South African waters using geometric morphometrics and to distinguish morphological groups and variation in these groups.
Cranial variation in common dolphins Delphinus spp. off South Africa, with the inclusion of information from the holotype of Delphinus capensis
There was a substantial difference between the composition of the dorsal-aspect and ventral- aspect clusters, suggesting the presence of only one species in South African waters.
Population ecological traits of Tursiops truncatus putative morphotypes in the transitional region of the Mexican Pacific Ocean
Introduction:  The bottlenose dolphin ( Tursiops truncatus ) exhibits high morphological and ecological variation not yet resolved for intraspecific systematics and population identity. Different
From Settlers to Subspecies: Genetic Differentiation in Commerson’s Dolphins Between South America and the Kerguelen Islands
C. c. kerguelenensis may represent the most recent diversification step of Cephalorhynchus, where isolation from their source population is driving a process of incipient speciation, and is consistent with the model of post-glacial colonization of KI by South American C. b. commersonii.
Distribution of Hector's dolphin (Cephalorhynchus hectori) off the west coast, South Island, New Zealand, with implications for the management of bycatch
To support decision making on placement of protected areas for Hector's dolphin on New Zealand's South Island west coast, we conducted three aerial surveys documenting the species' distribution in

Hector’s dolphins (Cephalorhynchus hectori hectori) are a small (~1.5 m long) marine dolphin, primarily inhabiting turbid, coastal waters discontinuously around the South Island of New Zealand. The
Distribution and abundance of Hector's dolphins off Otago, New Zealand
Abstract Data on the distribution and abundance of Hector's dolphins (Cephalorhynchus hectori) along the Otago coastline, between Taieri Mouth and Ōamaru (approximately 130 km alongshore), were
Geographical variation in franciscana (Pontoporia blainvillei) external morphology
The indication of a discontinuous distribution, consistency between genetic and morphological evidence, and a short time genetic divergence might indicate that franciscanas inhabiting FMA I represent a distinct subspecies.
Population Structure of Island-Associated Pantropical Spotted Dolphins (Stenella attenuata) in Hawaiian Waters
This research will address questions of dispersal patterns and gene flow among spotted dolphins near the Hawaiian Islands and explore genetic relationships among pantropical spotted dolphins around the main Hawaiian Islands.


Geographic Isolation of Hector’s Dolphin Populations Described by Mitochondrial DNA Sequences
The low rate of female dispersal, as indicated by this mitochondrial DNA structure, could increase the vulnerability of local populations to extinction due to fisheries‐related mortality.

Evidence is presented of a significant loss of mitochondrial DNA (mtDNA) diversity in two regional populations of Hector's dolphin in New Zealand, providing independent evidence of the severity of population decline and habitat contraction resulting from fisheries and perhaps other human activities.
Association patterns in three populations of Hector's dolphin, Cephalorhynchus hectori
The "half-weight index" was used to describe the association patterns in three previously unstudied populations of Hector's dolphin, Cephalorhynchus hectori, around the South Island of New Zealand.
Stocks of Dolphins (Stenella spp. and Delphinus delphis)in the Eastern Tropical Pacific: A Phylogeographic Classification
It is noted that the stock structure of ETP spinner dolphins is complex, with the whitebelly form exhibiting characteristics of a hybrid swarm between the eastern and pantropical subspecies, and there is little morphological basis at present for division of thewhitebelly spinner dolphin into northern and southern stocks.
Origin and radiation of Southern Hemisphere coastal dolphins (genus Cephalorhynchus)
The hypothesis that Cephalorhynchus is a monophyletic genus or that the four species have arisen separately from pelagic Lissodelphine species and have converged morphologically is investigated, and a pattern of radiation by colonization is proposed.
Molecular Analysis of mtDNA Types in Exploited Populations of Spinner Dolphins ( Stenella longirostris )
The results reinforce the morphologically-based hypothesis of non-uniqueness of the whitebelly form and suggest that relatively more emphasis should be placed on conservation of the endemic and presumably locally adapted eastern form.
Variation of spotted and spinner porpoise (genus Stenella) in the Eastern Pacific and Hawaii
Spotted and spinner porpoise occur in coastal and offshore tropical waters of the eastern and central Pacific, as well as elsewhere in world tropical waters. They are important in the tropical
Conservation of Hector's dolphins: The case and process which led to establishment of the Banks Peninsula Marine Mammal Sanctuary
1. Entanglement in gillnets constitutes the greatest known threat to populations of small cetaceans. In 1988, in response to data on the distribution and abundance, incidental catch, reproduction
Molecular genetic identification of southern hemisphere beaked whales (Cetacea: Ziphiidae)
To assist in the species‐level identification of stranded and hunted beaked whales, a database of ‘reference’ sequences from the mitochondrial DNA control region for 15 of the 20 described ziphiid species was compiled, showing that four of these ‘test’ specimens had initially been misidentified.
