ESTIMATING SIZE AND ASSESSING TRENDS IN A COASTAL BOTTLENOSE DOLPHIN POPULATION
A framework for determining the number of individuals present and assessing the likely time scale over which trends in abundance may be determined is used, appropriate for animal species that possess natural markings sufficient for individual recognition, and valuable in the development and implementation of management and monitoring programs for vulnerable populations.
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters
1. The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate and precise…
The Status of the World's Land and Marine Mammals: Diversity, Threat, and Knowledge
A comprehensive assessment of the conservation status and distribution of the world's mammals is presented, compiled by 1700+ experts, to suggest common mechanisms driving diversity and endemism across systems.
Habitat Use by Bottlenose Dolphins: Seasonal Distribution and Stratified Movement Patterns in the Moray Firth, Scotland
The stratification patterns amongst dolphins suggest that individuals do not move freely within the inner Moray Firth and therefore may be unable to move away from localized disturbance or pollution.
Cetacean abundance and distribution in European Atlantic shelf waters to inform conservation and management
Quantifying the influence of sociality on population structure in bottlenose dolphins.
This work applies recently developed analytical techniques to the population of bottlenose dolphins residing along the Scottish east coast, to detect the presence of communities within this population and infer its social structure from the temporal variation in association patterns between individuals.
Estimating relative energetic costs of human disturbance to killer whales (Orcinus orca)
Estimates of cetacean abundance in European Atlantic waters in summer 2016 from the SCANS-III aerial and shipboard surveys
Monitoring cetaceans in European waters
Monitoring spatial and temporal patterns in cetacean abundance involves a variety of approaches depending upon the target species and the resources available, and increasingly, spatial modelling using GLMs and GAMs is being used to provide a better understanding of the biotic and hydrographic factors influencing cetACEan distribution.
Habitat preference modelling as a conservation tool: proposals for marine protected areas for cetaceans in southern Spanish waters

As part of a project to identify marine protected areas (MPAs) in Spanish Mediterranean waters, habitat preference models were developed using 11 years of survey data to provide predictions of…
