Organization and social structure of the coastal bottlenose dolphin Tursiops truncatus in the Gulf de Guayaquil, Ecuador
A study on the coastal bottlenose dolphin was carried out between February 1990 and October 1992 in the inner estuary of the Gulf of Guayaquil, Ecuador (3 S, 80 W). In 143 boat surveys, a total of 4021–4351 dolphins in 241 groups were recorded. 441 different dolphins were identified by natural marks of which 1557 resightings were obtained. Based on resightings, it was established that this popu...
متن کاملSocial Structure Within the Bottlenose Dolphin (Tursiops truncatus) Population in the Shannon Estuary, Ireland
The Shannon Estuary is home to Ireland’s only known resident population of bottlenose dolphins (Tursiops truncatus) and is designated as a candidate Special Area of Conservation (cSAC) for this species. Proper conservation management of these dolphins requires an understanding of the social structure of this population. Four years of photoidentification data (2005 to 2009, excluding 2007) were ...
متن کاملBOTTLENOSE DOLPHIN (Tursiops truncatus): Western North Atlantic Coastal Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Stock Structure of the Coastal Morphotype A. Latitudinal distribution and structure along the coast
The coastal morphotype is continuously distributed along the Atlantic coast south of Long Island, around peninsula Florida and along the Gulf of Mexico coast. On the basis of differences in mtDNA haplotype frequencies, however, Curry (1997) concluded that the nearshore animals in the northern Gulf of Mexico and the western North Atlantic were significantly different and represent separate stock...
متن کاملBOTTLENOSE DOLPHIN (Tursiops truncatus): Northern Gulf of Mexico Bay, Sound, and Estuarine Stocks 2009
STOCK DEFINITION AND GEOGRAPHIC RANGE Bottlenose dolphins are distributed throughout the bays, sounds and estuaries of the Gulf of Mexico (Mullin 1988). The identification of biologically-meaningful " stocks " of bottlenose dolphins in these waters is complicated by the high degree of behavioral variability exhibited by this species (Shane et al. 1986; Wells and Scott 1999; Wells 2003), and by ...
متن کاملExodus! Large-scale displacement and social adjustments of resident Atlantic spotted dolphins (Stenella frontalis) in the Bahamas
Over the last 20 years, significant habitat shifts have been documented in some populations of cetaceans. On Little Bahama Bank (LBB) there are sympatric communities of resident Atlantic spotted dolphins (Stenella frontalis) and bottlenose dolphins (Tursiops truncatus), monitored since 1985. The size and social structure (three clusters: Northern, Central, Southern) have been stable among the s...
