چکیده

The utility of microsatellites for managing captive Tursiops truncatus was investigated. Specifically the level of genetic diversity among the loci examined and their usefulness for resolving paternity was assessed. Overall a relatively low level of genetic variation was found among captive dolphins. In addition, a high percentage of common alleles was found among dolphins belonging to different morphotypes (inshore versus offshore). The implications of these findings are discussed and suggestions are given for the use of genetic markers in captive propagation programs for T. truncatus.

Molecular Evidence of a Captive-Born Intergeneric Hybridization Between Bottlenose and Risso’s Dolphins: Tursiops truncatus × Grampus griseus

Natural hybridization occurs rarely in mammals, but it is thought to have the potential to produce viable hybrid offspring in cetaceans more easily than in other mammals. Among cases of cetacean hybridization, hybrids between bottlenose dolphins (Tursiops truncatus) and Risso’s dolphins (Grampus griseus) have been documented in both the wild and in captivity. However, until now, no molecular ev...

Bubble ring play of bottlenose dolphins (Tursiops truncatus): implications for cognition.

Research on the cognitive capacities of dolphins and other cetaceans (whales and porpoises) has importance for the study of comparative cognition, particularly with other large-brained social mammals, such as primates. One of the areas in which cetaceans can be compared with primates is that of object manipulation and physical causality, for which there is an abundant body of literature in prim...

Genetic diversity of bottlenose dolphin (Tursiops sp.) populations in the western North Pacific and the conservation implications

The evolutionary processes that shape patterns of diversity in highly mobile marine species are poorly understood, but important towards transferable inference on their effective conservation. In this study, bottlenose dolphins (Tursiops sp.) are studied to address this broader question. They exhibit remarkable geographical variation for morphology, life history, and genetic diversity, and this...

Insights about the genetic diversity and population structure of an offshore group of common bottlenose dolphins (Tursiops truncatus) in the Mid-Atlantic.

Although the genus Tursiops has a worldwide distribution and is globally well-studied, some dolphin populations continue to face high risks of decline. Hence, it is necessary to assess the genetic diversity and structure of this genus to properly assess its conservation status and to implement appropriate management actions. In Brazil, genetic studies on this group remain rare, particularly for...

Reliable microsatellite genotyping of dolphin DNA from faeces

Noninvasive samples have proved useful in genotyping studies of free-ranging mammals. However, potential genotyping errors associated with such samples dictate the need for validation studies. This pilot study demonstrates the use of dolphin faeces in multilocus microsatellite genotyping studies. An empirical approach to calculating the rate of genotyping error was applied to data from matched ...
