A 52-year archive of life history data for the world’s largest and most diverse population of endangered primates is now available for free download online. Fully updated in February 2019, the Duke Lemur Center database allows visitors to view and download data for more than 3,700 animals representing 27 species of lemurs, lorises, and galagos.
Since the DLC’s first data release in 2014, data has been downloaded by students, scientists, veterinarians, zoo professionals, and educators from 25 countries around the world. The 2019 update contains the same file types released with the original manuscript in 2014 and includes additional data collected over the intervening years. A total of 130 animals have been added to the database.
According to registry information collected via the Duke Lemur Center website, the majority of downloads have been by undergraduate students (26%) and graduate students (25%). 12% of downloads were by veterinarians and zoo professionals, and 7% were by high school students and educators. 62% of registrants used the data for research projects.
A “treasure trove” of data and its uses
The DLC’s treasure trove of data, which contains information about the lives, health, and habits of thousands of animals, dates from the center’s beginnings in 1966. The large sample sizes, exact dates of events, and longitudinal data that in many cases span an animal’s entire life make these data sets unique, particularly within the primate literature.
Because lemurs hang near the edge of extinction, it’s extremely unlikely that a collection of similar size will ever be recreated, says Sarah Zehr, a research scientist and Data Manager at the DLC. “Many of these species are critically endangered in the wild, so they’re unlikely to be held in captivity again. This means that the data are irreproducible.”
By making its data available to the world, the DLC hopes that the information will (a) help institutions better care for lemurs in captivity, and (b) help researchers and conservationists understand these animals in order to better protect them in the wild. Lemurs are the most endangered mammals on Earth, and by studying the variables that most affect their health, reproduction, and social dynamics, we learn how to most effectively focus our conservation efforts in Madagascar.
How to access
You can download the updated datasets from two locations – directly from the DLC website and from the curated data repository Dryad. Both locations contain both the original and updated data releases and all associated information.
