Data from: Life history profiles for 27 strepsirrhine primate taxa generated using captive data from the Duke Lemur Center
Since its establishment in 1966, the Duke Lemur Center (DLC) has accumulated detailed records for nearly 4200 individuals from over 40 strepsirrhine primate taxa – the lemurs, lorises, and galagos. Here we present verified data for 3627 individuals of 27 taxa in the form of a life history table containing summarized species values for variables relating to ancestry, reproduction, longevity, and body mass, as well as the two raw data files containing direct and calculated variables from which this summary table is built. Large sample sizes, longitudinal data that in many cases span an animal's entire life, exact dates of events, and large numbers of individuals from closely related yet biologically diverse primate taxa make these datasets unique. This single source for verified raw data and systematically compiled species values, particularly in combination with the availability of associated biological samples and the current live colony for research, will support future studies from an enormous spectrum of disciplines.
Figure 6 in Phylogeny and coevolutionary associations of makialgine mites (Acari, Psoroptidae, Makialginae) provide insight into evolutionary history of their hosts, strepsirrhine primates
Figure 6. Preferred TreeMap reconstruction of coevolutionary associations between strepsirrhine primates (bold) and makialgine mites using morphological data (see Table 4, no. 3). Filled circles indicate cospeciation, empty circles with crosses indicate extinctions, arrows indicate host switches, empty squares indicate speciation within a host lineage (duplication). As the multihost Lemuralges intermedius was arbitrarily restricted to Lemuridae only (see Material and methods), reconstructions involving Lemuralges (shown in grey) are incomplete and those involving Gaudalges may be biased because of this.
Figure 5 in Phylogeny and coevolutionary associations of makialgine mites (Acari, Psoroptidae, Makialginae) provide insight into evolutionary history of their hosts, strepsirrhine primates
Figure 5. Exploration of cost space to evaluate different coevolutionary scenarios in the observed association between strepsirrhine primates and makiagine mites using morphological data (codivergence cost is set to 0, extinction cost is set to 1). A, probability (P-values) was estimated using 100 000 permutations of both host and parasite terminals with a cospeciation cost and extinction cost of 0 and 1, respectively; B, significant values (P <0.05) are shaded and shown in detail. Dashed lines demark the cost space that corresponds to six significant coevolutionary models (as given in Table 3).

Figure 4. Single maximum parsimony tree of Makialginae (tree length = 76; consistency index without uninformative characters = 0.67; retention index = 0.76). Character numbers (see Appendix) are given above branches and their states below branches; homoplasies are indicated by empty circles. Ambiguous apomorphies are not shown. Bold numbers above branches are Bremer support indices.

Schematic representation of a makialgine mite (Makialginae): A, female hysterosoma, ventral view; B, chaetotaxy of legs I–IV, respectively; C, leg I, dorsal view; D, tarsus and distal part of tibia III, in dorsal view; E, tarsus IV of male, in lateral view. Filled circles indicate dorsal setae, empty circles indicate ventral setae.

Reconstructing dietary ecology of extinct strepsirrhines (Primates, Mammalia) with new approaches for characterizing and analyzing tooth shape
<p>The morphological and ecological diversity of lemurs and lorisiformes once rivalled the rest of the primate order. Here, we assemble a dataset of 3D models representing the second mandibular molars of a wide range of extant and fossil strepsirrhines encompassing this diversity. We use these models to distill quantitative descriptors of tooth form and then analyze these data using new analytical methods. We employ a recently developed dental topography metric (ariaDNE), which is less sensitive to details of random error in 3D model quality than previously used metrics (e.g., DNE); Bayesian multinomial modelling with metrics designed to measure overfitting risk; and a tooth segmentation algorithm that allows the shapes of disaggregated tooth surface features to be quantified using dental topography metrics. This approach is successful at reclassifying extant strepsirrhine primates to known dietary ecology and indicates that the averaging of morphological information across the tooth surface does not interfere with the ability of dental topography metrics to predict dietary adaptation. When applied to extinct species, many subfossil lemurs and the most basal fossil strepsirrhines are predicted to have been primarily frugivorous or gummivorous. This supports an ecological contraction among the extant lemurs and the importance of frugivory in the origins of crown Strepsirrhini, potentially to avoid competition with more insectivorous and folivorous members of Paleogene Afro-Arabian primate faunas.</p>
