low genetic diversity in the masked palm civet paguma larvata Viverridae
Journal of Zoology, 2009Co-Authors: Marie-lilith Patou, Jinping Chen, L Cosson, D H Andersen, Ettore Randi, Shuyi Zhang, Corinne Cruaud, Arnaud Couloux, Geraldine VeronAbstract:: The masked palm civet is distributed through south-east Asia, China and the Himalayas. Because of its potential role in the severe acute respiratory syndrome (SARS) epidemic, it has become important to gather information on this species, and notably to provide a tool to determine the origin of farm and market animals. For this purpose, we studied the genetic variability and the phylogeographic pattern of the masked palm civet Paguma larvata. First, two portions of mitochondrial genes, cytochrome b and the control region, were sequenced for a total of 76 individuals sampled from China, the Indochinese region and the Sundaic region. Results indicated a low genetic variability and suggested a lack of a phylogeographic structure in this species, which do not allow inferring the geographic origin of samples of unknown origin, although it is possible to distinguish individuals from China and the Sundaic region. This low variation is in contrast to the well-marked morphological differentiation between the populations in the Sundaic and Chinese-Indochinese regions. We also used five microsatellite loci to genotype 149 samples from two wild and four farmed populations in China, where the masked palm civet is farmed and where the SARS coronavirus was isolated. These analyses also showed a reduced variability in Chinese civets and showed that farmed populations did not exhibit a lower genetic diversity than wild populations, suggesting frequent introductions of wild individuals into farms.

phylogenetic relationships of the asian palm civets hemigalinae paradoxurinae Viverridae carnivora
Molecular Phylogenetics and Evolution, 2008Co-Authors: Marie-lilith Patou, Andrew P. Jennings, Régis Debruyne, Akbar Zubaid, Jeffrine Japning Rovieryan, Geraldine VeronAbstract:The Viverridae (Mammalia, Carnivora), one of the least studied groups of carnivorans, include two subfamilies of Asian palm civets: Hemigalinae and Paradoxurinae. The relationships between and within these two subfamilies have never been thoroughly tested using an extensive molecular sample set. In this study, we gathered sequences of four genes (two mitochondrial: Cytochrome b and ND2 and two nuclear: β-fibrinogen intron 7 and IRBP exon 1) for eight of the eleven extant species representing these two subfamilies. The results showed that: (1) the Asian palm civets (Hemigalinae and Paradoxurinae) have a single origin and form the sister-group of the (Genettinae + Viverrinae) clade, (2) the Hemigalinae (including the otter civet Cynogale bennettii) are monophyletic, (3) the Paradoxurinae are monophyletic and (4) the small-toothed palm civet (Arctogalidia trivirgata) is an early offshoot within the Paradoxurinae. Using a relaxed molecular clock analysis, the differentiation of the (Hemigalinae + Paradoxurinae) was inferred to occur in the Late Oligocene/Early Miocene.

PHYLOGÉNIE DES PETITS CARNIVORES FÉLIFORMES (MAMMALIA, CARNIVORA)
Bulletin De La Societe Zoologique De France, 2007Co-Authors: Geraldine VeronAbstract:De recents resultats de phylogenie moleculaire ont eclairci les relations phylogenetiques des carnivores feliformes et ont permis d'etablir la position de taxons debattus qui etaient auparavant inclus dans les Viverridae. La civette palmiste africaine, les civettes malgaches et les linsangs asiatiques ne sont desormais plus inclus dans les Viverridae, qui maintenant comprennent quatre sous-familles : les Hemigalinae (civettes palmistes a bandes et civette loutre), les Paradoxurinae (civettes palmistes et binturong), les Genettinae (genettes et poianes) et les Viverrinae (civettes terrestres). La civette palmiste africaine (Nandiniidae) est groupe-frere du reste des feliformes et les linsangs asiatiques (Prionodontidae) sont le groupe-frere des felins (Felidae). Les civettes malgaches (Euplerinae) et mangoustes malgaches (Galidiinae) forment un groupe monophyletique (Eupleridae), groupe frere des mangoustes (Herpestidae). Les Herpestidae sont eux-memes divises en deux sous-familles, les Herpestinae, regroupant les mangoustes solitaires et les Mungotinae, incluant les mangoustes sociales. Ces travaux ont egalement montre quels etaient les caracteres morphologiques ayant une valeur phylogenetique pour les carnivores feliformes.

Mosaics of convergences and noise in morphological phylogenies: what's in a viverrid-like carnivoran?
Systematic biology, 2005Co-Authors: Philippe Gaubert, W. Chris Wozencraft, Pedro Cordeiro-estrela, Geraldine VeronAbstract:Adaptive convergence in morphological characters has not been thoroughly investigated, and the processes by which phylogenetic relationships may be misled by morphological convergence remains unclear. We undertook a case study on the morphological evolution of viverrid-like feliformians (Nandinia, Cryptoprocta, Fossa, Eupleres, Prionodon) and built the largest morphological matrix concerning the suborder Feliformia to date. A total of 349 characters grouped into four anatomical partitions were used for all species of Viverridae and viverrid-like taxa plus representatives of the Felidae, Hyaenidae, Herpestidae, and one Malagasy mongoose. Recent molecular phylogenetic analyses suggest that viverrid-like morphotypes appeared independently at least three times during feliformian evolution. We thus used a synthetic molecular tree to assess morphological evolutionary patterns characterizing the viverrid-like taxa. We examined phylogenetic signal, convergence and noise in morphological characters using (a) tree-length distribution (g1), (b) partitioned Bremer support, (c) RI values and their distribution, (d) respective contributions of diagnostic synapomorphies at the nodes for each partition, (e) patterns of shared convergences among viverrid-like taxa and other feliformian lineages, (f) tree-length differences among alternative hypotheses, and (g) the successive removal of convergent character states from the original matrix. In addition, the lability of complex morphological structures was assessed by mapping them onto the synthetic molecular tree. The unconstrained morphological analysis yielded phylogenetic groupings that closely reflected traditional classification. The use of a synthetic molecular tree (constraint) combined with our thorough morphological investigations revealed the mosaics of convergences likely to have contributed to part of the historical uncertainty over viverrid classification. It also showed that complex morphological structures could be subjected to reversible evolutionary trends. The morphological matrix proved useful in characterizing several feliformian clades with diagnostic synapomorphies. These results support the removal from the traditionally held Viverridae of several viverrid-like taxa into three distinct families: Nandiniidae (Nandinia), Prionodontidae (Prionodon), and the newly defined Eupleridae (including Cryptoprocta, Fossa, Eupleres plus all "mongoose-like" Malagasy taxa). No clearly "phylogenetically misleading" data subsets could be identified, and the great majority of morphological convergences appeared to be nonadaptive. The multiple approaches used in this study revealed that the most disruptive element with regards to morphological phylogenetic reconstruction was noise, which blured the expression of phylogenetic signal. This study demonstrates the crucial need to consider independent (molecular) phylogenies in order to produce reliable evolutionary hypotheses and should promote a new approach to the definition of morphological characters in mammals.

First report of a chinchilla phenotype in Viverridae (Carnivora)
2013Co-Authors: Philippe Gaubert, Sylvain DufourAbstract:We report on the first case of a chinchilla phenotype in Viverridae (Carnivora), on the basis of a skin of Hausa Genet Genetta thierryi originating from Reserve de Faune de Kankan, Republic of Guinea. The specimen exhibits pale rufous brown spots likely to have been caused by eumelanin degradation, and uniform pale creamy orange background coloration probably due to lower concentration of phaeomelanin.

phylogenetic systematics and tempo of evolution of the viverrinae mammalia carnivora Viverridae within feliformians implications for faunal exchanges between asia and africa
Molecular Phylogenetics and Evolution, 2006Co-Authors: Philippe Gaubert, Pedro CordeiroestrelaAbstract:We reconstructed the phylogeny of the subfamily Viverrinae (Mammalia, Carnivora, Viverridae) using a approximately 3kb data set in order to reassess timing and patterns of faunal exchanges between Asia and Africa. Maximum parsimony, maximum likelihood, and Bayesian analyses of separated and combined matrices (cytochrome b, transthyretin intron I and IRBP exon 1 [IRBP1]) recovered all the well-supported relationships within feliformian lineages. In addition, IRBP1 supported paraphyly of genus Herpestes and contributed to the resolution of equivocal hypotheses within Viverridae, including (1) the monophyly of Viverrinae, and (2) Viverricula sister-group of the other terrestrial civets (Civettictis and Viverra). The combined analysis yielded a robust phylogeny, recovering monophyly of Prionodontidae and yielding high posterior probabilities for nodes (1) (Prionodontidae, Felidae) and (2) ((Felidae, Prionodontidae), ((Hyaenidae, (Herpestidae, Eupleridae)), Viverridae)). Using a fossil cross-validation method, we estimated the emergence of Viverridae at 34.29Myr, with a separation between the three traditional subfamilies Hemigalinae, Paradoxurinae, and Viverrinae during the Late Oligocene-Early Miocene. The terrestrial civets and the splits between (1) Civettictis and Viverra and (2) Poiana and Genetta were estimated to appear during the Middle Miocene. Parsimony- and maximum likelihood-based methods yielded unambiguous ancestral area reconstructions, including the Asian origin of the family Viverridae, the subfamily Viverrinae, the terrestrial civets and the clade (Civettictis, Viverra). On the grounds of genetic distances, morphological divergence, and divergence time estimates, we propose the erection of the subfamily Genettinae (including Genetta and Poiana). Our analyses suggested two independent migration events from Asia to Africa, during the Middle Miocene (Civettictis) and between the Late Oligocene and Middle Miocene (Genettinae). These results are in agreement with the hypothesis of Miocene routes from Asia to Africa-via the Arabian microplate-that would have involved several independent events of migrations. Couched in the context of the viverrid fossil record, our study calls for a revision of the paleontological data in order to fully appreciate the complexity of Afro-Asian faunal exchanges.

first molecular evidence for reassessing phylogenetic affinities between genets genetta and the enigmatic genet like taxa osbornictis poiana and prionodon carnivora Viverridae
Zoologica Scripta, 2004Co-Authors: Philippe Gaubert, Michel Tranier, Annesophie Delmas, Marc Colyn, Geraldine VeronAbstract:Gaubert, P., Tranier, M., Delmas, A.-S., Colyn, M. & Veron, G. (2004). First molecular evidence for reassessing phylogenetic affinities between genets (Genetta) and the enigmatic genet-like taxa Osbornictis, Poiana and Prionodon (Carnivora, Viverridae). —Zoologica Scripta, 33, 117–129. The subfamily Viverrinae is a composite group of carnivores comprising the large and plantigrade terrestrial civets (Civettictis, Viverricula and Viverra) and the slender and generally more arboreal genets and genet-like taxa (Genetta, Prionodon, Poiana, Osbornictis), both having Asiatic and African representatives. The problematic phylogenetic relationships between genets and genet-like taxa are addressed for the first time from a molecular perspective through complete cytochrome b gene sequences. We used a large taxonomic sample set including some very rare and crucial species such as Osbornictis piscivora, Poiana richardsonii (museum specimen material) and Genetta johnstoni. The results from parsimony, distance and maximum likelihood analyses do not support the monophyly of the Viverrinae and contradict previous morphological hypotheses. The Asiatic linsangs (Prionodon spp.) are excluded from the Viverrinae and represent either a basal Feliformia or Viverridae. The other genet-like taxa constitute a strongly supported monophyletic African group, in which the African linsang (represented by Poiana richardsonii) is a sister group to the genets. The aquatic genet Osbornictis piscivora is included within the latter clade, and the genus Osbornictis should be considered a junior synonym of Genetta. African and Asiatic terrestrial civets are monophyletic, but their phylogenetic affinities with the genet-like clade are inconclusive using our data set. On the basis of our molecular results, morphological convergences and adaptations to peculiar habitats and ways of life within genets and genet-like taxa are discussed.

systematique et biogeographie des herpestidae et Viverridae mammalia carnivora en asie
2008Co-Authors: Marie-lilith PatouAbstract:L’Asie est une region presentant une importante biodiversite et abrite ainsi plusieurs hotspots. Son climat tropical, son histoire geologique complexe, les variations climatiques qui ont eu lieu depuis le Tertiaire jusqu’au Pleistocene et enfin sa fragmentation insulaire (iles d’Asie du sud-est) sont autant de facteurs susceptibles d’avoir genere cette diversite. Ainsi, un certain nombre d’hypotheses biogeographiques ont ete avancees dans la litterature pour expliquer la distribution et la richesse specifique observee. Les Herpestidae (mangoustes) et les Viverridae (genettes et civettes) sont deux groupes de mammiferes carnivores presents en Afrique et en Asie. Nous avons etudie la phylogenie de ces groupes avec une attention particuliere pour leurs representants asiatiques, a partir des donnees moleculaires. Nous avons egalement etudie la phylogeographie, c’est-a-dire la distribution des differentes lignees dans l’espace, de plusieurs especes ou groupes d’especes proches. L’ensemble de ces donnees ont ete replacees dans un contexte temporel. Nous avons realise des analyses de datations moleculaires chez ces differents groupes afin de confronter ces resultats avec les hypotheses paleoclimatiques et paleobiogeographiques proposees. Ces resultats montrent que les Herpestidae asiatiques ainsi que les Hemigalinae et Paradoxurinae (deux sous-familles strictement asiatiques de Viverridae) forment des groupes monophyletiques qui se seraient diversifies a partir de la fin de l’Oligocene-debut du Miocene. Par la suite, differentes variations climatiques et topographiques auraient induit de nombreux evenements de diversifications au sein de chacun de ces groupes et nous avons cherche a mettre en relation ces deux parametres pour comprendre la facon dont la biodiversite s’est mise en place en Asie. Nous avons ainsi verifie un certain nombre de barrieres biogeographiques et suggere l’existence de differentes zones de refuges glaciaires en Asie

Molecular epidemiology of rabies virus in South Africa: evidence for two distinct virus groups.
The Journal of general virology, 1995Co-Authors: B F Von Teichman, G R Thomson, C D Meredith, L H NelAbstract:In order to derive phylogenetic relationships between rabies virus isolates from different geographical locations and host species in South Africa, two genome regions of the virus, viz. the cytoplasmic domain of the glycoprotein and the G-L intergenic region (pseudogene), were sequenced. A high level of nucleic acid sequence conservation indicated a close phylogenetic relationship between virus isolates from domestic dogs, jackals and bat-eared foxes, i.e. Canidae. These isolates appeared to be distinct from but closely related to European strains of rabies virus. However, a phylogenetically distinguishable and distant group, which contained isolates from mongooses (i.e. Viverridae) was identifiable. The latter group appears to be distantly related to European and vaccine strains of rabies virus and may have evolved uniquely on the central plateau of South Africa. Our data also indicate that spillover from mongooses (or other viverrids) to canid hosts occurs occasionally.
