Reproductive success of male Atlantic spotted dolphins (Stenella frontalis) revealed by noninvasive genetic analysis of paternity
Cetaceans are known to frequently engage in sexual behavior; however, the lack of male parental investment in offspring makes assessment of male reproductive success difficult. We assessed paternity in a small population (mean individuals sighted per year = 93) of Atlantic spotted dolphins (Stenella frontalis (G. Cuvier, 1829)) utilizing noninvasively collected fecal material. Samples (n = 88) ...
متن کاملPANTROPICAL SPOTTED DOLPHIN (Stenella attenuata): Western North Atlantic Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of spotted dolphin in the Western Atlantic — the Atlantic spotted dolphin, Stenella frontalis, formerly S. plagiodon (Perrin et al. 1987), and the pantropical spotted dolphin, S. attenuata. These species are difficult to differentiate at sea. The pantropical spotted dolphin is distributed worldwide in tropical and some sub-tropical oce...
متن کاملEcholocation signals of wild Atlantic spotted dolphin (Stenella frontalis).
An array of four hydrophones arranged in a symmetrical star configuration was used to measure the echolocation signals of the Atlantic spotted dolphin (Stenella frontalis) in the Bahamas. The spacing between the center hydrophone and the other hydrophones was 45.7 cm. A video camera was attached to the array and a video tape recorder was time synchronized with the computer used to digitize the ...
متن کاملWhistles emitted by Atlantic spotted dolphins (Stenella frontalis) in Southeastern Brazil.
The whistles of Atlantic spotted dolphins have been studied in a few localities of the North Atlantic Ocean and those studies revealed that the species emits whistles within a broad frequency range, with a high number of inflection points and presence of harmonics. In the South Atlantic Ocean, there is no information about the sounds produced by Atlantic spotted dolphins. A total of 1092 whistl...
متن کاملNoninvasive methodology for the sampling and extraction of DNA from free-ranging Atlantic spotted dolphins
Genetic sampling and molecular investigations are important parts of studying wild populations. However, collecting tissues from free-ranging animals can be difficult or impractical. This study develops a sampling and extraction protocol for template DNA from faecal material collected in a marine environment from small cetaceans. DNA was extracted from faecal material of free-ranging Atlantic s...
