Abstract We investigated the potential for using mark–recapture models to estimate abundance of bottlenose dolphin populations in open systems (e.g., bays, estuaries). A major challenge these is that immigration and emigration occur during sampling, thus violating one most basic assumptions models. assumed dolphins our study site were composed both residents (those used area almost exclusively study), transients passed through but did not remain long), examined several estimators their...
The adjacency of 2 marine biogeographic regions off Cape Hatteras, North Carolina (NC), and the proximity Gulf Stream result in a high biodiversity species from northern southern provinces coastal pelagic habitats. We examined spatiotemporal patterns mammal strandings evidence human interaction for these along NC shorelines evaluated whether diversity stranded animals reflected published...
A marked increase in the frequency of harbor porpoises ( Phocoena phocoena ) stranded North Carolina 2005 was declared as an Unusual Mortality Event (UME). Strandings occurred January through May when are seasonally present. Increased stranding rates were measured relative to a threshold determine that UME occurring. The analysis also revealed elevated strandings during 1999, undeclared year. Recovered carcasses 1999 and accounted for 39% 261 1997–2009. During 2005, 43 strandings, primary or...
Abstract Diet studies are fundamental for understanding trophic connections in marine ecosystems. In the southeastern US, common bottlenose dolphin Tursiops truncatus is predominant mammal coastal waters, but its role as a top predator has received little attention. of piscivorous predators, like dolphins, start with assessing prey otoliths recovered from stomachs or feces, digestive erosion hampers species identification and underestimates fish weight (FW). To compensate, FW often estimated...
The social structure of estuarine-resident bottlenose dolphins is complex and varied. Residing in habitats often utilized for resource exploitation, are at risk due to anthropogenic pressures while still federally protected. Effective conservation predicated upon accurate abundance estimates. In North Carolina, two stocks (demographically independent groups) common dolphin have been designated using spatiotemporal criteria. Both subjected bycatch fishing gear. southern Carolina estuarine...
Each fishery presents its own challenges for observers to document bycatch. The North Carolina (NC) stop net is especially challenging because it uses anchored gear (the net) that soaks up 15 days herd fish, which are then hauled shore via another (a beach seine). Three Tursiops truncatus (Bottlenose Dolphin) entanglements in nets and six Bottlenose Dolphin strandings, each suspected of having been entangled based on injuries noted (lesions) spatio-temporal overlap with the fishery, were...
Abstract Sea turtle bycatch has been documented in the large-mesh gillnet fishery that targets flounder estuarine waters of North Carolina (NC). However, only portions operated under Endangered Species Act Incidental Take Permits and had regular observer coverage to determine occurrence extent sea bycatch. From June through November 2009, an Alternative Platform Observer Program (APOP) was initiated southeastern Carteret County, NC, document entanglements. Observers covered 1.6% total number...
