Background While cetaceans have been extensively studied around the world, nocturnal movements and habitat use have been largely unaddressed for most populations. We used satellite telemetry to examine the nocturnal movements and habitat use of four bottlenose dolphins (Tursiops truncatus) from a well-studied population in a complex estuary along t...

Information on movement patterns and habitat selection for critical activities are fundamental to understanding and managing animal populations. While bottlenose dolphins (Tursiops truncatus) inhabiting the Indian River Lagoon (IRL), Florida, are known to exhibit long-term residency, data regarding short-term movement and association patterns, habi...

Network analysis has recently been used to delve into the dynamics of cetacean sociality. Few studies, however, have addressed how habitat shape influences sociality, specifically how linear water bodies constrain the space where individuals might interact. We utilized network and spatiotemporal analyses to investigate association patterns and comm...

Bottlenose dolphins ( Tursiops truncatus ) in northern New Zealand range widely and their coastal distribution increases their risk of exposure to a variety of threats. Marine protected areas (MPAs) are increasingly used to protect species but there is a paucity of studies examining their efficacy. In the Bay of Islands, New Zealand (35°14'S, 174°0...

A common goal of many ecologists is to understand the spatial distribution of a species. Determining factors responsible for this distribution aids in predicting how animals respond to changes in their environment and explains other aspects of a populations‟ ecology such as social structure and foraging strategies. This thesis examines the demograp...
