Females are able to reproduce on average once every two to six-years. While twins may be possible, they are rare when compared to the far more numerous single births. The Flinders team’s recently published research – Passadore, C., Möller, L., Diaz-Aguirre, F., and Parra, G. J.

Female dolphins formed preferred associations and social clusters which ranged from overlapping to discrete home ranges. The Burrunan dolphin (Tursiops australis) is a rare and endangered species of bottlenose dolphins, with two genetically distinct year-round resident populations in Victoria.There are currently about 120 dolphins in Port Phillip Bay and 65 dolphins in the Gippsland Lakes.

In the study, Dr. Diaz-Aguirre and colleagues used generalized affiliation indices, combined with social networks, reproductive condition, and genetic data to investigate drivers of associations in female Burrunan dolphins. “Just like in human communities, Burrunan dolphins tend to form family groups, with those females most closely related genetically forming close social relationships in … “These close social groups among related females appear to be vital for them while raising young calves, or for those without calves who also combine due to similar biological requirements related to feeding and mating.”, “As well as key pointers on social evolution and behavior in these highly complex marine mammals, our study also provides important information for their conservation.”. F. Diaz-Aguirre et al. Finally, the Atlantic spotted dolphin can be found in tropical and sub-tropical waters ranging from the coast of Florida to the Indian Ocean; the darker coloring and stouter beak serve to identify this species. 2011) The Burrunan dolphin is the most ancestral node of all Tursiops (bottlenose) species (Moura et al. Interaction between marine mammals and vessels, as well as tourism operations, are regulated through the National Parks and Wildlife (Protected Animals – Marine Mammals) Regulations 2010, which places restrictions on the distance and speed of vessels approaching dolphins, and restrictions on swimmers and food provisioning.

Protecting and conserving marine wildlife will ensure that future generations are able to enjoy a more diverse and secure natural world. Dolphins are able to enjoy a great variety of fish and other marine life when it comes to finding a meal, and whole pods of dolphins can often be seen in the area when on the hunt. The Burrunan dolphin was formally described and named in 2011 by MMF’s Founding Director Dr Kate (Charlton-Robb et al. Burrunan Dolphin. “Dolphins that have such localised movement patterns are particularly susceptible to localised human pressures that could negatively impact upon them, such as habitat degradation and loss, entanglements in marine debris, interaction with fisheries (such as bycatch or reduction in prey availability due to overfishing) and pollution, among others.”. The study appears in the journal Scientific Reports. “Just like in human communities, Burrunan dolphins tend to form family groups, with those females most closely related genetically forming close social relationships in specific areas,” said Dr. Fernando Diaz-Aguirre, a researcher in the Cetacean Ecology, Behaviour and Evolution Lab and the Molecular Ecology Lab at the Flinders University’s College of Science and Engineering. South Australia 5042, South Australia | Northern Territory A Burrunan dolphin calf is cared for by its mother for between 3-5 years. “Our field studies are not only important for understanding the evolution of complex animal societies, but for providing information to conservation managers to sure the future survival of these unique dolphin populations.”, “Small resident populations of dolphins are particularly vulnerable to changes in the environment, and represent sentinels of the health of coastal ecosystems.”. The different species of dolphins that can be found in the waters of Florida have long been a popular attraction for residents and visitors of the area alike. Ensuring that these animals and the ecology of the region are able to enjoy a brighter and more secure future is not an issue that should be left to chance. Kinship and reproductive condition correlate with affiliation patterns in female southern Australian bottlenose dolphins. The social relationships, cooperative hunting techniques and complex dynamics that dolphins enjoy shape many aspects of their daily lives. And within such areas, we need to ensure that dolphin populations remain protected and secure, with good management. Burrunan dolphins in Victoria. A large proportion (56%) even restrict their space use to particular embayments within Coffin Bay.

Therefore, Dr Parra argues that current and future activities and developments, as well as marine parks zoning arrangements in the area, should all consider the local dolphins in their management strategies.
