On Genetic Data, Models, Storytelling and Consensus: (Re)Constructing the Demographic History of Homo sapiens and Its Putative Admixture with Neanderthals
The importance of well protected forests for the conservation genetics of West African colobine monkeys
In tropical forests, anthropogenic activities are major drivers of the destruction and degradation of natural habitats, causing severe biodiversity loss. African colobine monkeys (Colobinae) are mainly folivore and strictly arboreal primates that require large forests to subsist, being among the most vulnerable of all nonhuman primates. The Western red colobus Piliocolobus badius and the King colobus Colobus polykomos inhabit highly fragmented We…

Genetic Differentiation and Demographic History of the Northern Rufous Mouse Lemur (Microcebus tavaratra) Across a Fragmented Landscape in Northern Madagascar

Averting Lemur Extinctions amid Madagascar's Political Crisis
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions.
New density estimates of a threatened sifaka species ( Propithecus coquereli ) in Ankarafantsika National Park
Propithecus coquereli is one of the last sifaka species for which no reliable and extensive density estimates are yet available. Despite its endangered conservation status [IUCN, 2012] and recognition as a flagship species of the northwestern dry forests of Madagascar, its population in its last main refugium, the Ankarafantsika National Park (ANP), is still poorly known. Using line transect distance sampling surveys we estimated population densi…
Noninvasive molecular sexing: An evaluation and validation of the SRY‐ and amelogenin‐based method in three new lemur species
Many lemur species are arboreal, elusive, and/or nocturnal and are consequently difficult to approach, observe and catch. In addition, most of them are endangered. For these reasons, non‐invasive sampling is especially useful in primates including lemurs. A key issue in conservation and ecological studies is to identify the sex of the sampled individuals to investigate sex‐biased dispersal, parentage, social organization and population sex ratio.…
Density Estimates of Two Endangered Nocturnal Lemur Species From Northern M adagascar: New Results and a Comparison of Commonly Used Methods
Very little information is known of the recently described M icrocebus tavaratra and L epilemur milanoii in the D araina region, a restricted area in far northern M adagascar. Since their forest habitat is highly fragmented and expected to undergo significant changes in the future, rapid surveys are essential to determine conservation priorities. Using both distance sampling and capture–recapture methods, we estimated population densities in two …
Spatial variation in density and total size estimates in fragmented primate populations: The golden‐crowned sifaka ( Propithecus tattersalli )
The golden‐crowned sifaka ( Propithecus tattersalli ) is an endangered lemur species found only in the Daraina region, a very restricted area in north‐eastern Madagascar. Its forest habitat is highly fragmented and expected to suffer from significant changes in the near future. The species is poorly known and only one census study, carried out in 2000, has ever been published. It is thus crucial to update the conservation status of the golden‐cro…
Clinal Variation in the Nuclear DNA of Europeans
Allele frequencies are clinally distributed for many protein polymorphisms in Europe, suggesting that the current populations are derived from an ancestral group that expanded from the Near East. It is not yet fully established whether that expansion took place during the Neolithic or earlier or whether the detectable protein variation faithfully reflects the underlying molecular variation. In this study we address the latter question by describi…
Natural and anthropogenic determinants of genetic structure in the largest remaining population of the endangered golden‐brown mouse lemur, Microcebus ravelobensis
Genetic differentiation between natural populations is best understood as a result of both natural and anthropogenic factors. Genetic studies on large populations still living under relatively undisturbed conditions are extremely valuable to disentangle these influences. The effect of three natural (geographic distance, landscape, dispersal) factors and two anthropogenic factors (road, savannah) on gene flow was analyzed in the largest remaining …
The Neolithic transition in Europe: Comparing Broad Scale Genetic and Local Scale Isotopic Evidence
Genetic studies of modern populations are raising many interesting questions about how far the modern gene pool is owed to incoming populations during the agricultural revolution in Neolithic Europe. But, as the authors show, studies of isotopic data from cemeteries reveal a picture of increasing subtlety at local level. While early farmers may have been initially newcomers in the upper Rhine they may also have soon intermarried with contemporary…
