TL;DR: This study demonstrates that genetic tagging is not only feasible, but generates data that can be valuable when interpreting the results of tagging experiments, and allows the first estimates of animal abundance based solely on genotypic data.

TL;DR: In this paper, the authors conducted a two-year ocean-basinwide photographic and biopsy study in 1992-1993 to resolve uncertainties about population size, as well as the spatial and genetic structure of the humpback whale population in the North Atlantic.

TL;DR: The results of a double-marking experiment using natural markings and microsatellite genetic markers to identify humpback whales (Megaptera novaeangliae) confirm that natural markings are a reliable means of identifying individuals on a large scale.

TL;DR: In this paper, a set of criteria for evaluating photographic quality and individual distinctiveness were developed involving judgments about overall quality or distinctiveness and about specific aspects of each of the judges.

TL;DR: In this article, the authors carried out dedicated surveys over three summers in the southern Inner Hebrides and used generalised additive models (GAMs) to predict areas of high relative density for harbour porpoises for each year.
