Distribution. NE Madagascar from the Bemarivo River, near Sambava, S to the region of Mananara-Nord, including the Masoala Peninsula and possibly extending from Marojejy W into Tsaratanana; there are additional isolated and most likely introduced populations in the Betampona Strict Nature Reserve and on Nosy Mangabe and on Ile Roger (also called Aye-aye I) near the town of Mananara-Nord. The distribution S of Mananara needs to be clarified because significant hybridization with the Brown Lemur (FE. fulvus) occurs over a wide area. in Lemuridae

Distribution. NW Madagascar, probably restricted to the Sambirano region, including the Ampasindava Peninsula; the N extent ofits distribution is possibly the Sambirano River and the S limit is the Andranomalaza (= Maetsamalaza) River.

Distribution. NW Madagascar, the core distribution seems to be to the N and E of the Betsiboka River as far as the Bay of Narinda, and this is also the species present in Ankarafantsika National Park. The isolated population farther N in the Ankarana region may also be this species, but, in between, the Sambirano Woolly Lemur (A. unicolor) inhabits both the Ampasindava Peninsula and the Sambirano region, including the Manongarivo Special Reserve. in Indriidae

RADseq data reveal a lack of admixture in a mouse lemur contact zone contrary to previous microsatellite results

Microsatellites have been a workhorse of evolutionary genetic studies for decades and are still commonly in use for estimating signatures of genetic diversity at the population and species level across a multitude of taxa. Yet, the very high mutation rate of these loci is a double-edged sword, conferring great sensitivity at shallow levels of analysis (e.g., paternity analysis) but yielding considerable uncertainty for deeper evolutionary comparisons. For the present study, we used reduced representation genome-wide data (RADseq) to test for patterns of interspecific hybridization previously characterized using microsatellite data in a contact zone between two closely related mouse lemur species in Madagascar (Microcebus murinus and M. griseorufus). We revisit this system by examining populations in, near, and far from the contact zone, including many of the same individuals that had previously been identified as hybrids with microsatellite data. Surprisingly, we find no evidence for admixed nuclear ancestry. Instead, re-analyses of microsatellite data and simulations suggest that previously inferred hybrids were false positives and that the program NewHybrids can be particularly sensitive to erroneously inferring hybrid ancestry. Combined with results from coalescent-based analyses and evidence for local syntopic co-occurrence, we conclude that the two mouse lemur species are in fact completely reproductively isolated, thus providing a cautionary tale for the inference of interspecific hybridization with microsatellite data.

Data from: Blood transcriptomes reveal novel parasitic zoonoses circulating in Madagascar's lemurs

Zoonotic diseases are a looming threat to global populations, and nearly 75% of emerging infectious diseases can spread among wildlife, domestic animals and humans. A 'One World, One Health' perspective offers us an ideal framework for understanding and potentially mitigating the spread of zoonoses, and the island of Madagascar serves as a natural laboratory for conducting these studies. Rapid habitat degradation and climate change on the island are contributing to more frequent contact among humans, livestock and wildlife, increasing the potential for pathogen spillover events. Given Madagascar's long geographical isolation, coupled with recent and repeated introduction of agricultural and invasive species, it is likely that a number of circulating pathogens remain uncharacterized in lemur populations. Thus, it is imperative that new approaches be implemented for de novo pathogen discovery. To this end, we used non-targeted deep sequencing of blood transcriptomes from two species of critically endangered wild lemurs (Indri indri and Propithecus diadema) to characterize blood-borne pathogens. Our results show several undescribed vector-borne parasites circulating within lemurs, some of which may cause disease in wildlife, livestock and humans. We anticipate that advanced methods for de novo identification of unknown pathogens will have broad utility for characterizing other complex disease transmission systems.

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.
