Integrative taxonomy clarifies the evolution of a cryptic primate clade
Elst, Tobias van; Sgarlata, Gabriele M.; Schüßler, Dominik; Tiley, George P.; Poelstra, Jelmer W.; Scheumann, Marina; Blanco, Marina B.Global biodiversity is under accelerating threats, and species are succumbing to extinction before being described. Madagascar’s biota represents an extreme example of this scenario, with the added complication that much of its endemic biodiversity is cryptic. Here we illustrate best practices for clarifying cryptic diversification processes by presenting an integrative framework that leverages multiple lines o...

Comparative conservation genetics of several threatened lemur species living in...
Salmona, JordiHow natural climate cycles and human driven impact, such as glacial/interglacial patterns drought and humid periods, or (is)land colonization, have shaped species distribution and forest cover is still subject to debate. Disentangling how natural factors and anthropogenic pressures contributed to the current landscape structure is crucial to understand landscape and wildlife dynamics and to improve predictions ...
Genomics and the challenging translation into conservation practice
Shafer, Aaron B.A.; Wolf, Jochen B.W.; Alves, Paulo C.; Bergström, Linnea; Bruford, Michael W.; Brännström, Ioana; Colling, Guy; Dalén, LoveThe global loss of biodiversity continues at an alarming rate. Genomic approaches have been suggested as a promising tool for conservation practice as scaling up to genome-wide data can improve traditional conservation genetic inferences and provide qualitatively novel insights. However, the generation of genomic data and subsequent analyses and interpretations remain challenging and largely confined to academi...
Conservation Status and Abundance of the Crowned Sifaka (Propithecus coronatus)
Salmona, Jordi; Rasolondraibe, Emmanuel; Jan, Fabien; Besolo, Aubin; Rakotoarisoa, Heriniaina; Meyler, Sam Viana; Wohlhauser, SébastienThe crowned sifaka (Propithecus coronatus) is Endangered. It has a large but highly fragmented distribution; its known range extends from the Betsiboka River in the north of Madagascar, to the Mahavavy River in the north-west, and down to the Tsiribihina River in the south-west. The species lives in forest habitats that are highly and increasingly fragmented and are continuously suffering perturbations and dest...
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...
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...
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...
Effective Population Size Dynamics and the Demographic Collapse of Bornean Oran...
Sharma, Reeta; Arora, Natasha; Goossens, Benoit; Nater, Alexander; Morf, Nadja; Salmona, Jordi; Bruford, Michael W.; Van Schaik, Carel P.Bornean orang-utans experienced a major demographic decline and local extirpations during the Pleistocene and Holocene due to climate change, the arrival of modern humans, of farmers and recent commercially-driven habitat loss and fragmentation. The recent loss of habitat and its dramatic fragmentation has affected the patterns of genetic variability and differentiation among the remaining populations and incre...
