    L’espĂšce de camĂ©lĂ©on Furcifer labordi, bien connue pour son cycle biologique le plus court parmi les vertĂ©brĂ©s est distribuĂ©e dans la forĂȘt sĂšche du Sud-ouest de Madagascar entre les deux fleuves, Tsiribihina et Fiherenana. Toutefois, sa longĂ©vitĂ© varie selon l’axe latitudinal. La population du nord, Ă  Kirindy est capable de vivre plus longtemps que celle de la partie sud, Ă  Ranobe. Les facteurs extrinsĂšques Ă  l’origine de cette variation ne sont pas encore dĂ©terminĂ©s. Nous avons menĂ© des Ă©tudes dans la RĂ©serve SpĂ©ciale d’Andranomena afin d’explorer les paramĂštres Ă©cologiques dĂ©terminant cette longĂ©vitĂ©. L’investigation a rĂ©vĂ©lĂ© que la prĂ©sence d'un groupe particulier d'insectes ainsi que les caractĂ©ristiques de microhabitat, Ă  savoir les couvertures de la canopĂ©e, le recouvrement et l’épaisseur de la litiĂšre et la densitĂ© d’arbres de plus de 1 m de hauteur ont une influence sur la longĂ©vitĂ© de cette espĂšce de camĂ©lĂ©on. Par contre, aucune influence n’a Ă©tĂ© constatĂ©e par la perturbation de l'habitat, l’abondance de prĂ©dateur comme les rapaces et la prĂ©sence d’un serpent prĂ©dateur.   The chameleon species Furcifer labordi, well known for its shortest life cycle among vertebrates, is distributed in the dry forest of southwestern Madagascar between Tsiribihina and Fiherenana rivers. However, this longevity varies along a latitudinal axis. The population in the north, in Kirindy, is able to live longer than that in the southern part, in Ranobe. The extrinsic factors responsible for this variation have not been yet identified. We have carried out studies in the Andranomena Special Reserve to explore the ecological parameters determining this longevity. The investigation revealed that the presence of a particular group of insects as well as the microhabitat characteristics including canopy covers, leaf litter cover and thickness as well as tree density greater than 1 m in height have an influence on the longevity of this chameleon species. On the other hand, no influence was observed by habitat disturbance, the abundance of predators such as raptors and the presence of a predatory snake

    Site-based conservation is widely recognized as a fundamental requirement for the maintenance of  biodiversity. We carried out a rapid biological assessment from 17 March to 14 May 2011 in the southwestern part of the provisionally protected rainforest corridor between Marojejy, Anjanaharibe-Sud and Tsaratanana protected areas (COMATSA), northern Madagascar, to assess its biodiversity richness and species conservation status. We recorded 248 endemic vertebrate species, including 80 amphibians, 52 reptiles, 79 birds, 27 small mammals and 10 lemurs. Of these 248 species, 36 are threatened including one Critically Endangered (one lemur), nine Endangered (two amphibians, four reptiles and three lemurs) and 26 Vulnerable (10 amphibians, six reptiles, four birds, one small mammal and five lemurs). For herpetofauna species, the pair COMATSAc –cMarojejy was the only site that had a similarity value greater than 0.50. For birds and  lemurs, values of similarity in three pairs of sites COMATSAc –c Marojejy, COMATSA c –c Anjanaharibe-Sud and Marojejyc –c Anjanaharibe-Sud exceeded those of herpetofauna in COMATSAc –c Marojejy. The inclusion of the COMATSA into the new protected area network in Madagascar is supported by our findings. Il est dorĂ©navant largement reconnu que pour maintenir la biodiversitĂ©, il est fondamental de rĂ©aliser la  conservation de la nature au niveau des sites. Un inventaire biologique rapide a Ă©tĂ© menĂ© du 17 mars au 14 mai 2011 dans la partie sud-ouest du couloir forestier reliant les parcs et rĂ©serves du Marojejy,  d’Anjanaharibe- Sud et du Tsaratanana (COMATSA). L’inventaire de ce couloir qui bĂ©nĂ©ficie d’un statut de protection temporaire dans la partie septentrionale de Madagascar, Ă©tait destinĂ© Ă  Ă©valuer la richesse de sa biodiversitĂ© et le statut de conservation des espĂšces de vertĂ©brĂ©s qu’il hĂ©berge. Les rĂ©sultats ont   montrĂ© que parmi les 248 espĂšces endĂ©miques de vertĂ©brĂ©s recensĂ©es, 80 sont des amphibiens, 52 des  reptiles, 79 des oiseaux, 27 des petits mammifĂšres mammifĂšres et 10 des lĂ©muriens. Sur ces 248  espĂšces, 36 sont menacĂ©es, dont une espĂšce qui est en Danger Critique d’Extinction (lĂ©murien), neuf en Danger (deux amphibiens, quatre reptiles et trois lĂ©muriens) et 26 VulnĂ©rables (1 0 amphibiens, six  reptiles, quatre oiseaux, un micromammifĂšre et cinq lĂ©muriens). Ce couloir forestier prĂ©sente un  coefficient de similaritĂ© Ă©levĂ©, d’une valeur supĂ©rieure Ă  0.50 avec le Marojejy pour les amphibiens et les reptiles. Pour les oiseaux et les lĂ©muriens, les coefficients sont encore plus importants, plus  particuliĂšrement dans les comparaisons COMATSAc –c Marojejy, COMATSAc –c Anjanaharibe- Sud et Marojejyc –c Anjanaharibe-Sud. Cette Ă©tude confirme l’importance d’intĂ©grer le COMATSA dans le rĂ©seau des Aires ProtĂ©gĂ©es de Madagascar pour renforcer la protection des espĂšces de vertĂ©brĂ©s endĂ©miques et menacĂ©es

    Perceived socio-economic impacts of the marbled crayfish invasion in Madagascar

    The negative environmental and economic impacts of many invasive species are well known. However, given the increased homogenization of global biota, and the difficulty of eradicating species once established, a balanced approach to considering the impacts of invasive species is needed. The marbled crayfish (Procambarus virginalis) is a parthenogenetic freshwater crayfish that was first observed in Madagascar around 2005 and has spread rapidly. We present the results of a socio-economic survey (n = 385) in three regions of Madagascar that vary in terms of when the marbled crayfish first arrived. Respondents generally considered marbled crayfish to have a negative impact on rice agriculture and fishing, however the animals were seen as making a positive contribution to household economy and food security. Regression modeling showed that respondents in regions with longer experience of marbled crayfish have more positive perceptions. Unsurprisingly, considering the perception that crayfish negatively impact rice agriculture, those not involved in crayfish harvesting and trading had more negative views towards the crayfish than those involved in crayfish-related activities. Food preference ranking and market surveys revealed the acceptance of marbled crayfish as a cheap source of animal protein; a clear positive in a country with widespread malnutrition. While data on biodiversity impacts of the marbled crayfish invasion in Madagascar are still completely lacking, this study provides insight into the socio-economic impacts of the dramatic spread of this unique invasive species.

    Furcifer labordi est une espĂšce de camĂ©lĂ©ons uniquement connue dans quelques localitĂ©s de la partie occidentale de Madagascar. Son aire de distribution est restreinte entre les fleuves Tsiribihina et Fiherenana.  Nous avons rĂ©alisĂ© des recherches pour comprendre sa distribution Ă©cologique et spatiale dans la Reserve SpĂ©ciale d’Andranomena. Des investigations ont Ă©tĂ© menĂ©es dans les habitats proche et loin de cours d’eau, Ă  la lisiĂšre et l’intĂ©rieur de la forĂȘt et dans la forĂȘt relativement intacte et celle en rĂ©gĂ©nĂ©ration. Nos rĂ©sultats ont rĂ©vĂ©lĂ© que cette espĂšce se rĂ©partit uniformĂ©ment dans les diffĂ©rents types d’habitats. Autrement dit, sa distribution horizontale n’est pas influencĂ©e ni par la dĂ©gradation de l’habitat, ni par le cours d’eau. La couverture de la canopĂ©e et la repartition des plantes selon la hauteur de l’extĂ©rieur vers l’itĂ©rieur de la forĂȘt sont des paramĂštres qui influencent cette distribution horizontale. Les oiseaux (six espĂšces) et les serpents (quatre espĂšces) prĂ©dateurs ne provoquent pas de perturbation sur F. labordi et n’influencent pas sa distribution horizontale.

Its distribution area is restricted between the Tsiribihina and Fiherenana rivers. We carried out research to understand its ecological and spatial distribution in the Andranomena Special Reserve. Investigations were carried out in habitats near and far from watercourses, at the edge and interior of the forest and in relatively intact and regenerating forest. Our results revealed that this species is evenly distributed across different habitat types. In other words, its horizontal distribution is not influenced either by habitat degradation or by the watercourse. The cover of the canopy and the distribution of plants according to height from the outside to the inside of the forest are parameters that influence this horizontal distribution. Predatory birds (six species) and snakes (four species) do not cause any disturbance to F. labordi and do not influence its horizontal distribution. The latter is not as influenced by the abundance of available insects. The height of the perch used varies a lot, however it is not linked to age class or sex. F. labordi generally shows no particular preference regarding the choice of plant used as a perch. The same goes for the height and DBH of perching plants. The species uses available plant parts similarly and shows no particular preference. All age classes were observed and do not show any particular preference in terms of habitat types. Our results suggest that the restricted distribution of this species could be due to the disappearance of its habitat

    Protected area surface extension in Madagascar: Do endemism and threatened species remain useful criteria for site selection ?

    The ‘hotspot approach’ considers that endemism and threatened species are key factors in protected area designation. Three wetland and forest sites have been proposed to be included into Madagascar’s system of protected areas (SAPM – SystĂšme des Aires ProtĂ©gĂ©es de Madagascar). These sites are Manambolomaty (14,701 ha) and Mandrozo (15,145 ha) in the west and Bemanevika (37,041 ha) in the north. Biodiversity inventories of these three sites recorded 243 endemic species comprised of 44 reptiles, 54 amphibians, 104 birds, 23 small mammals, 17 lemurs and one fish. Of these 243 species, 30 are threatened taxa comprising two Critically Endangered (CR), 11 Endangered (EN) and 17 Vulnerable (VU) species. The long term ecological viability of these sites has been shown by population stability of the two Critically Endangered flagship species, the Madagascar fish eagle (Haliaeetus vociferoides) in Manambolomaty and Mandrozo and the recently rediscovered Madagascar pochard (Aythya innotata) in Bemanevika. Other threatened species and high biological diversity also justifies their inclusion into Madagascar’s SAPM
