Breeding Success at Duke Lemur Center

Pia and Conrad are doing well.

Just over a month ago, Pia and Conrad were fighting to survive. Pia had a uterine infection after giving birth to Conrad, and her milk wasn't coming in. Dedicated Primate Technicians and a skilled veterinary staff worked day and night to care for mom and infant, and it paid off. Now both are thriving.

Every life matters. With endangered species, each life takes on special importance. The animals at the Duke Lemur Center represent a genetic safety net for lemurs in the wild in Madagascar - the only place in the world where lemurs occur naturally. So every infant feels like a success.

This spring has been a good one for the breeding program at Duke Lemur Center. Just after Conrad was born, Drusilla, another Coquerel's sifaka, gave birth to Pompeia. This time mom and infant both did well from the beginning, and they are continuing to thrive. In fact, if you call 919.489.3364 x 0 for a tour, you can see mom and infant playing happily.

The Coquerel's sifaka are not the only lemurs having breeding success at Duke Lemur Center. This past week-end Foster, a Blue-eyed black lemur gave birth to twins. It's early days for the twins, and life for every species is fragile - particularly perinatally, but today mom and twins are doing well.

The Ring-tailed lemurs also had infants this spring. We have already had a set of twins and an additional single infant. All are doing well. There is a lot to celebrate at Duke Lemur Center this spring. Come see for yourself. If you can't come by, adopt a lemur. There are lots of ways to help save these precious animals.

It seems that we in the research department are a bit behind the times in blog world, as I see that the education and conservation departments are already up and running, illuminating their forks of our trifocal mission at the Duke Lemur Center. We will not be left behind, I say! And so, I would like to introduce Research at the Duke Lemur Center. I am often asked why we do research on these animals and what types of research we do. First things first, which means addressing the first question of why we do research on lemurs. How will that help their plight in the wild and their survival in captivity.

The use of captive animals for scientific research ultimately helps conservation efforts of wild populations in a number of ways. It stands to reason that the more we can learn about endangered species, the better our chances of conserving them. By studying the biology of these animals in areas such as behavior, reproduction, morphology, physiology, ontogeny, and genetics in a controlled environment, we can better define species and subspecies status, better quantify their ecological requirements, better understand their interactions with other species, and better determine a conservation plan given the animals and environment we have to work with. In addition, we do a number of research projects that focus on animal husbandry and care so that we can keep our animals happy and healthy here in Durham.

The Duke Lemur Center houses the largest and most diverse captive prosimian colony in the world, and these animals are used by investigators both at Duke and other national and international academic institutions for both species-specific and comparative research. Only non-invasive research is allowed at our facility, and all projects must be approved by both the DLC Research Committee and the Duke University Institutional Animal Care and Use Committee (IACUC), both of which contain veterinary oversight, before any research can begin. By maintaining these animals at the Duke Lemur Center and allowing experts in the US and international scientific communities to carry out studies of the animals in our colony, we take an important step toward the long-term goal of lemur conservation. Stay tuned for descriptions of the projects we are working on here at the DLC!
