Habitat loss is the leading cause of reptile decline and therefore, habitat studies are crucial to implement conservation actions. We investigated the microhabitat use of the Manapany day gecko (Phelsuma inexpectata), a critically endangered species endemic to Reunion Island (Western Indian Ocean). Anthropogenic disturbances led to a severe fragmen...

The reproductive phenology of tropical geckos varies considerably between species. We investigated the reproductive timing of Phelsuma inexpectata, a critically endangered tropical squamate endemic to Reunion Island (west-ern Indian Ocean). From February 2018 to August 2020 (30 months), we carried out monthly monitoring of laying sites. Phelsuma in...

Ce document a pour objectif de renforcer les capacités en matière de collecte de données de répartition pour l'herpétofaune sur le département de La Réunion (Océan Indien). Il s’agit d’une méthode de récolte de données, qui est inspirée du protocole de suivi des populations de reptiles pour la France métropolitaine rédigé par Lourdais & Miaud (2016...

Feasibility study for breeding young geckos

Characterization of the breeding structure, zootechnics and breeding monitoring

Observation about the reproduction of the changeable lizard, Calotes versicolor (Daudin, 1802) (Squamata : Agamidae), in Reunion Island. A female laying eggs was observed in february 2019.

Recovery plan for Phelsuma borbonica and Phelsuma inexpectata

The after Margouillator®: “repticide” products available in shops on La Réunion Island, Indian Ocean. A product intended to kill lizards, the Margouillator®, was commonly used and readily available on Reunion Island in the 2000s until it was stopped some 10 years later. We analyze here all products freely available in Reunion and used to replace t...

A skink and gecko inventory of a closed forest near Poindimié, New Caledonia, was carried out using and comparing five detection protocols, visual and nocturnal encounter, pitfall traps, plots and sticky traps. Nine species of skinks and seven of geckos were found out of a total of 346 observations. Visual encounter surveys have emerged as the best...

IUCN assessment

We surveyed the Iles Eparses (Europa, Juan de Nova, Iles Glorieuses and Tromelin) in the Western Indian Ocean for terrestrial reptiles. We reviewed the literature and data on museum specimens, then used data recorded from field surveys and International Union for Conservation of Nature (IUCN) criteria to analyze habitat occupation and to map the di...

Technical report about CMR monitoring of Manapany day gecko populations

The importance of long-distance dispersal (LDD) in shaping geographical distributions has been debated since the nineteenth century. In terrestrial vertebrates, LDD events across large water bodies are considered highly improbable, but organismal traits affecting dispersal capacity are generally not taken into account. Here, we focus on a recent li...

Technical procedure to preserve Phelsuma borbonica populations located in forest kiosks in Reunion Island

Phelsuma borbonica Mertens, 1966 (Sauria: Gekkonidae) on “La Réunion”. II. Ecology and ethology. Informations about the eco-ethology of Phelsuma borbonica in the wild on “La Réunion” are scattered. This paper provides a review of such knowledge, from available literature information and from the database of the NGO Nature Ocean Indien. Diet, reprod...

Réunion Island landscapes are today characterised by a complex mosaic of ecosystems in varying degrees of alteration. Changes in natural areas result in hybrid ecosystems, retaining some original characteristics (e.g. native species) as well as novel elements (e.g. introduced species). Previous studies demonstrate that substantially modified areas...

Résumé – Les informations relatives à l’éco-éthologie de Phelsuma borbonica en milieu naturel sur l’île de La Réunion sont dispersées. Cet article fournit une synthèse de ces connaissances, à partir de toutes les informations disponibles dans la bibliographie et de la base de données de l’association Nature Océan Indien. L’alimentation de ce gecko,...

We provide a review on the knowledge of the alien herpetofauna knowledges in La Réunion (Indian Ocean). This work has been carried out using bibliographic and observation data (1818 data). Sixteen species are now naturalized on the island: 12 lizards, two ophidians and two amphibians. These taxa have been introduced from other islands of the Southw...

Alien reptile

Skinks predation by Egretta dimorpha

The giant day gecko Phelsuma grandis, endemic to Madagascar, was introduced to Reunion Island (Indian Ocean) in the mid-1990s. No studies have been conducted so far to define its precise distribution and habitat. To fill the knowledge gap about this invasive species, we compiled available data and performed field work during 2007-2014. We detected...

Lygodactyllus verticillatus (Gekkonidae) predation by Nephila madagascariensis (Nephilidae)

The pollination ecology and breeding system of Trochetia granulata (Malvaceae), an endemic tree species from Réunion were studied. In 2010–2011, compatibility studies were conducted on a total of 154 flowers from 35 different individuals using three different hand pollination treatments: (a) autofertility, (b) self-pollination and (c) cross-pollina...

Interspecific kleptoparasitism (the stealing of already-procured items from other species) has received little attention in tropical reptiles. We report here the second case of kleptoparasitism in tropical lizards, and the first known case of pollen theft by a vertebrate species. Phelsuma inexpectata, a gekkonid lizard endemic to Réunion, was obser...

Mormopterus francoismoutoui elevation record

Le grand gecko vert de Madagascar (Phelsuma grandis) est une espèce invasive sur l’île de La Réunion. Il constitue une menace pour la faune locale, notamment pour l’entomofaune et l’herpétofaune. En 2013, un Plan Régional de Lutte fournit une stratégie de gestion de cette espèce. Initié pour une durée de 5 ans, ce plan s’articule en deux objectifs...

Phelsuma grandis Gray, 1870 est un gecko introduit sur l'île de La Réunion. Le régime alimentaire de ce reptile, considéré comme invasif, a été étudié afin d'évaluer la menace qu'il pourrait représenter pour la faune indigène. Le contenu stomacal de 171 individus a été analysé. À La Réunion, P. grandis se nourrit principalement d'Arthropodes. Les r...

Withelist proposition for non native reptiles on Réunion Island

During the construction of a water storage tank for a hydroelectric plant, areas of natural habitat of the Reunion day gecko were destroyed by embankments of deposited excavated material. To offset this impact and encourage the gecko's return, 40 artificial egg laying site (AELS) were established in the area between September 2009 and July 2010. An...

Rapid inventory of herpetofauna on Koumac Islands, New Caledonia

The Manapany day gecko Phelsuma inexpectata Mertens, 1966 endemic to the south of Réunion Island, is a threatened species currently closely associated with the coastal habitat, one of the most endangered ecosystem on the island. We investigated the extent and the evolution of its distribution and its population size and density. We found that the s...
