Signature of a Pre-Human Population Decline in the Critically Endangered Reunio...
Salmona, Jordi; Salamolard, Marc; Fouillot, Damien; Ghestemme, Thomas; Larose, Jerry; Centon, Jean-François; Sousa, Vitor; Dawson, Deborah A.The exceptional biodiversity of Reunion Island is threatened by anthropogenic landscape changes that took place during the 350 years of human colonization. During this period the human population size increased dramatically from 250 to 800,000. The arrival of humans together with the development of agriculture, invasive species such as rats and cats, and deforestation has lead to the extinction of more than hal...
The Confounding Effect of Population Structure on Bayesian Skyline Plot Inferen...
Heller, Rasmus; Chikhi, Lounes; Siegismund, Hans RedlefMany coalescent-based methods aiming to infer the demographic history of populations assume a single, isolated and panmictic population (i.e. a Wright-Fisher model). While this assumption may be reasonable under many conditions, several recent studies have shown that the results can be misleading when it is violated. Among the most widely applied demographic inference methods are Bayesian skyline plots (BSPs), ...
A DNA Metabarcoding Study of a Primate Dietary Diversity and Plasticity across ...
Quéméré, Erwan; Hibert, Fabrice; Miquel, Christian; Lhuillier, Emeline; Rasolondraibe, Emmanuel; Champeau, Julie; Rabarivola, Clément; Nusbaumer, LouisIn tropical regions, most primary ecosystems have been replaced by mosaic landscapes in which species must cope with a large shift in the distribution of their habitat and associated food resources. Primates are particularly vulnerable to habitat modifications. Most species persist in small fragments surrounded by complex human-mediated matrices whose structure and connectivity may strongly influence their disp...
Taille de la population d’Avahi laniger dans la réserve d’Ambodiriana-Manompana...
Sabin, E.; Delarue, C.; Misandeau, C.; Besse, P.; Salmona, J.; Chikhi, L.Avahi laniger est le seul lémurien nocturne appartenant à la famille des Indriidae qui habite les forêts humides de l’est de Madagascar (Mittermeier et. al., 2010) dont une partie disparaît chaque année (exploitation du bois, pratique du «tavy» ou culture sur brûlis) (Beaucent and Fayolle, 2011; Lehman and Wright, 2000). La fragmentation et la destruction de leur habitat ainsi que la chasse menacent la survie d...
Survey of the critically endangered Perrier’s sifaka (Propithecus Perrieri) acr...
Salmona, J.; Jan, F.; Rasolondraibe, E.; Zaranaina, D.; Ousseni, D.S.; Mohamed-Thani, I.; Rakotonanahary, A.; Ralantoharijaona, T.; Kun-Rodrigues, C.Propithecus perrieri (Perrier’s sifaka) is one of the most endangered lemur species due to its small and fragmented distribution range. Despite a Critically Endangered (CR) conservation and flagship species status, there are still many uncertainties regarding its actual distribution and its presence in some forests of its putative distribution range. We report the results of diurnal and nocturnal surveys carrie...
Noninvasive molecular sexing: An evaluation and validation of the SRY- and amel...
Vanpé, Cécile; Salmona, Jordi; Pais, Isa; Kun-Rodrigues, Célia; Pichon, Claire; Meyler, Samuel Viana; Rabarivola, Clément; Lewis, Rebecca J.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 or...
The scaling of genetic diversity in a changing and fragmented world
Arenas, M.; Mona, S.; Trochet, A.; Sramkova Hanulova, A.; Currat, M.; Ray, N.; Chikhi, L.; Rasteiro, R.; Schmeller, D.S.; Excoffier, L.Most species do not live in a constant environment over space or time. Their environment is often heterogeneous with a huge variability in resource availability and exposure to pathogens or predators, which may affect the local densities of the species. Moreover, the habitat might be fragmented, preventing free and isotropic migrations between local sub-populations (demes) of a species, making some demes more i...
Extensive survey of the Endangered Coquerel’s sifaka Propithecus coquereli
Salmona, J; Jan, F; Rasolondraibe, E; Besolo, A; Ousseni, DS; Beck, A; Zaranaina, R; Rakotoarisoa, H; Rabarivola, CJ; Chikhi, LCoquerel’s sifaka Propithecus coquereli has a large but highly fragmented distribution. Despite its Endangered (EN) IUCN conservation status, uncertainties persist regarding its actual distribution and its presence in forests that are thought to be part of its distribution range. We provide here the first extensive population surveys of Coquerel’s sifaka across a large number of forest fragments neighboring 27 ...
New density estimates of a threatened sifaka species (Propithecus coquereli) in...
Kun-Rodrigues, Célia; Salmona, Jordi; Besolo, Aubin; Rasolondraibe, Emmanuel; Rabarivola, Clément; Marques, Tiago A.; Chikhi, LounèsPropithecus 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 s...
Daraina sportive lemur (Lepilemur milanoii) density and population size estimat...
Salmona, J.; Ralantoharijaona, T.; Thani, I.M.; Rakotonanahary, A.; Zaranaina, R.; Jan, F.; Rasolondraibe, E.; Barnavon, M.; Beck, A.; Wholhauser, S.The population of the Daraina sportive lemur (Lepilemur milanoii) is believed to be mostly confined to the Loky-Manambato region (Louis et al., 2006). Very little is known about L. milanoii and it is classified as “Data Deficient” by the IUCN (IUCN, 2013; Schwitzer et al., 2013). Despite the management of the area by the NGO Fanamby since 2005, no study had been conducted to determine the presence and the abund...
