Capture‐recapture methods are frequently employed to estimate abundance of cetaceans
using photographic techniques and a variety of statistical models. However, there are many …

We conducted a mark‐recapture survey of bottlenose dolphins Tursiops truncatus in the
bays, sounds, and estuaries of North Carolina during July 2000, using photographic …

Motivated by the need to estimate the abundance of marine mammal populations to inform
conservation assessments, especially relating to fishery bycatch, this paper provides …

Bay, sound and estuary (BSE) populations of bottlenose dolphins are common along the US
Atlantic and Gulf of Mexico coasts. NOAA Fisheries currently identifies 9 BSE stocks in the …

Recognizing individual animals using cues of colour pattern and shape is an everyday
occurrence. Of course, other physical cues such as size, and behavioural cues such as …

Methods for reliably identifying and monitoring individuals are critically important to
understanding the behavior of animals. Naturally occurring distinctive features have proven …

In 1997 the US National Marine Fisheries Service (NMFS) established the Mid-Atlantic
Bottlenose Dolphin Photo-ID Catalog (MABDC). This catalog is part of a NMFS program to …

Knowledge of demographic parameters of most cetacean populations is scarce because of
problems associated with sampling open populations of wide-ranging animals. In recent …

Misidentification of animals is potentially important when naturally existing features (natural
tags) are used to identify individual animals in a capture–recapture study. Photographic …

Monitoring spatial and temporal patterns in cetacean abundance involves a variety of
approaches depending upon the target species and the resources available. As a first step …
