It is postulated that deep-water foraging in sperm whales, Physeter macrocephalus, has led to communal care of young and long-term female bonds. By studying the social organization of a second, unrelated, deep-diving species, the northern bottlenose whale, we investigated the role that deep diving may play in the evolution of cetacean sociality. Northern bottlenose whales in a deep-water canyon, the Gully off Nova Scotia, Canada, form small groups (XSD=3.041.86). Associations within age/sex…

Behavioural Ecology Traits of Elusive Deep-Diver Whales Unravel a Complex Social Structure Influenced by Female Philopatry and Defence Polygyny
Knowledge of the role of individual associations has provided an insightful understanding of the structures of animal societies, especially in highly social mammals such as primates. Yet, this is
Moving in concert: Social and migratory behaviour of dolphins and whales in the North
A new model for Risso’s dolphin societies known as a stratified social organisation, which differs from fission-fusion and matrilineal society models is proposed, with strong associations between adult males and between adult females.
The bottlenose dolphin community of Doubtful Sound features a large proportion of long-lasting associations
A small, closed population of bottlenose dolphins living at the southern extreme of the species' range is described, which hypothesise that ecological constraints are important factors shaping social interactions within cetacean societies.
Prolonged maternal investment in northern bottlenose whales alters our understanding of beaked whale reproductive life history
The weaning strategy and nursing duration in northern bottlenose whales (Hyperoodon ampullatus) is examined by measuring stable isotopes deposited in dentine growth layer groups (GLGs), indicating that nursing is prolonged and weaning does not conclude until whales are 3–4 years old, substantially later than previous estimates of 1 year.

Sperm whale social organization in the GoC best fitted a constant companion/casual acquaintance model, where permanent units sizes were 12.5 individuals and two units usually associated together to form a group.
Abundance and behavioural ecology of bottlenose dolphins (Tursiops truncatus) in the Marlborough Sounds, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Conservation Biology at Massey University
This research's primary focus was to establish baseline information on the behavioural ecology of bottlenose dolphins, Tursiops truncatus in and around the Marlborough Sounds, New Zealand.
Status of northern bottlenose whales
The northern bottlenose whale, Hyperoodon ampullatus, is a beaked whale found only in the northern North Atlantic. It is a deep-diver, primarily using waters >500m deep. Whaling was concentrated in
Social Structure Within the Bottlenose Dolphin (Tursiops truncatus) Population in the Shannon Estuary, Ireland
The results found little evidence of social stability or group fidelity for this study’s dolphin population, which appears to live in a fission-fusion based society.
Heterogeneity and the markrecapture assessment of the Scotian Shelf population of northern bottlenose whales (Hyperoodon ampullatus)
A population of northern bottlenose whales (Hyperoodon ampullatus) inhabits the waters along the edge of the Scotian Shelf. The most important habitat of this population is the Gully, a large

Using suction–cup attached time–depth recorder/VHF radio tags, the first diving data is obtained on northern bottlenose whales (Hyperoodon ampullatus), the first such data on any species within the family Ziphiidae, suggesting that these whales may make greater use of deep portions of the water column than any other mammal so far studied.
Sperm whale social units : variation and change
Sperm whale photoidentification data spanning 12 years of study around the Galapagos Islands were examined to investigate the size, variability, and stability of social units, suggesting that the benefits of remaining in a social unit usually outweigh selection for some optimal unit size.

Babysitting in sperm whales seems to be a form of alloparental care, and its benefit may have been an important factor in the evolution of sociality in female sperm whales.
Northern bottlenose whales (Hyperoodon ampullatus) are consistently found through the year in the Gully, a prominent submarine canyon on the edge of the Scotian Shelf. Individuals were
Social organization and population structure of northern bottlenose whales in the Gully.
The social organization and population structure of northern bottlenose whales (Hyperoodon ampullatus) in the Gully was studied from 1988--1997 using photo-identification techniques, and the results scaled to account for the remainder of the population.
Two levels of alliance formation among male bottlenose dolphins (Tursiops sp.).
This study documents multiple-level male alliances within a social group outside of humans for bottlenose dolphins in Shark Bay, Western Australia.
Diving behaviour of the sperm whale, Physeter macrocephalus, off the Galapagos Islands
Sperm whales, Physeter macrocephalus, were tracked by means of a recording depth sounder in the waters off the Galapagos Islands, and usually started to make regular clicks when 150–300 m deep, which is approximately the depth of the oxygen minimum.

This volume should be of benefit to students of cetology and researchers in other areas of behavioral and conservation ecology, as well as anyone with a serious interest in the world of whales and dolphins.
Patterns of Female Attractiveness in Indian Ocean Bottlenose Dolphins
In Shark Bay, Western Australia, it is documented for the first time patterns of female attractiveness that may correspond to multiple oestrous cycles, supporting predictions of a promiscuous mating system in bottlenose dolphins.
Resource and habitat use of northern bottlenose whales in the Gully: Ecology, diving and ranging behaviour.
Northern bottlenose whales show a concentrated distribution within the Gully, a submarine canyon off the coast of eastern Canada, and the potential function of this local abundance is analyzed in terms of foraging behaviour, movements and distributional preferences.
