Duke Lemur Center Database

The DLC life history data are now available for download!

Release Date:   23 July 2014


Data Summary:   Since its establishment in 1966, the Duke Lemur Center has accumulated detailed records for nearly 4200 individuals from over 40 closely related yet biologically diverse prosimian primate taxa. Here we release verified data for over 3600 of them, representing the 27 taxa in the table below. The large sample sizes, exact dates of events, and longitudinal data that in many cases span an animal’s entire life make these datasets unique, particularly within the primate literature. Visitors can download a life history table containing summarized species values for variables relating to ancestry, reproduction, longevity, and body mass, as well as two raw data files containing direct and calculated variables for the individual animals from which the summary table is built. We hope that this single source for verified raw data and systematically compiled species values, particularly in combination with associated biological samples and the current live colony for research — all available at the Duke Lemur Center — will support future studies from an enormous spectrum of investigators.

What’s New:   As we release updates in the future that contain additional individuals, variables, and/or taxa, please refer to this “What’s New” section to find out what has been added or changed since the previous release.

**The Duke Lemur Center requires identifying information about researchers, students, and educators who download data so that we can demonstrate levels of use to funding agencies. Your registration information will only be used by the DLC for these purposes and will not be shared with a third party.**

What you will see on the data download page: Downloadable data and associated information are organized into four folders, listed below with the information you will find in each.

*A list of the 27 species included, including taxonomic abbreviations
*A pdf version of the published paper (the pdf version does not contain all tables)

*Reference and analytic versions of the DLC life history table. Using the reference version (27 species columns x 91 variable rows), it may be easier to look up specific data points. The analytic version (91 variable columns x 27 species rows) is more difficult to read but can be imported directly into statistical software for analysis.
*A list of variable descriptions and usage notes for the DLC Life History Table

*The DLC Animal List data file, containing 32 variables for 3,627 individuals representing 27 taxa in all stages of life
*A list of variable descriptions and usage notes for the DLC Animal List data file

*The DLC Weight data file, containing 33 variables relating to 65,692 weight measurements across 2174 individuals and 27 taxa
*A list of variable descriptions and usage notes for the DLC Weight data file
