Distribution and Habitat of the Invasive Giant Day Gecko Phelsuma Grandis Gray 1870
Phelsuma 22 (2014); 13-28 Distribution and habitat of the invasive giant day gecko Phelsuma grandis Gray 1870 (Sauria: Gekkonidae) in Reunion Island, and conservation implication Mickaël Sanchez1,* and Jean-Michel Probst1,2 1 Nature Océan Indien, 6, Lotissement les Magnolias, Rivière des Roches, 97470 Saint-Benoît, La Réunion, France 2 Nature et Patrimoine, 2, Allée Mangaron, Dos d’Ane, 97419 La Possession, La Réunion, France * Corresponding author; e-mail: [email protected] Abstract. 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 13 distinct populations of P. grandis, occurring mainly in the northern part of Reunion Island and on the west coast. This gecko inhabits human disturbed areas (gardens, urban parks, bamboos, orchards, coconuts, and banana plantation) and secondary habitats (shrubby savanna, and secondary dry woodlands, secondary dry and wet thickets). Its distribution strongly suggests that saltatory dispersal (through deliberate and/or accidental transport) and natural colonization are the mechanisms of spreading through Reunion Island. All our data in combination with both P. grandis ecology and native environmental range suggested that this gecko may colonize native forest, and constitutes a potential important threat to the native biodiversity of Reunion Island (arthropods and lizards). Key words. Phelsuma grandis, Reunion Island, distribution, invasive species, conservation. Introduction Day geckos of the genus Phelsuma are distributed in the western Indian Ocean (Austin et al. -

Republic of Seychelles is an archipelago of 116 islands located in the Western Indian Ocean east of East Africa. Across all 116 islands, Seychelles has a total land area of 455 square kilometers. The country consists of two distinct island groups: the Mahé group, in the north, and a chain of low-lying coral islands stretching away to the south. All of the country’s principal islands belong to the Mahé group; they include Mahé Island (the largest at 27 kilometers long and 11 kilometers wide), Praslin Island, Silhouette, La Digue and 28 smaller islands. The 83 coral islands are largely without water resources, and most are uninhabited. The population of Seychelles (2017 estimate) is 93,920. Victoria, on Mahé Island, is the capital, principal city and leading port of Seychelles. While more than 75% of the country’s population lives on Mahé Island, about 10% on Praslin, and others on La Digue and the outer islands. ANSE INTENDANCE, MAHÉ Visitor Arrivals Seychelles is known for its coral beaches, opportunities for water sports, UNESCO heritage sites, its abundant wildlife and nature reserves and its year-long tropical climate. The government of Seychelles strictly controls tourism development in the country to protect and conserve the fragile ecosystem of the islands, and also to enable the long-term sustainability of the sector, which depends heavily on the country’s MARKET SNAPSHOT: SEYCHELLES - HUNDRED ISLANDS OF PARADISE | PAGE 2 ecological offerings. -
Secret Seychelles Islands with Ponant Aboard Le Jacques Cartier
SECRET SEYCHELLES ISLANDS WITH PONANT ABOARD LE JACQUES CARTIER Embark with PONANT on an expedition cruise to discover the most beautiful islands of the Seychelles.

ATOLL RESEARCH BULLETIN NO. 365 ISSUED BY NATIONAL MUSEUM OF NATU HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C., U.S.A. June 1992 CHAPTER 1 INTRODUCTION TO THE SOVIET- ERICAN EXPEDITION TO THE SEUCHELLES ISWDS The First Soviet-American Expedition in arine Biology to the Seychelles Islands was organized by the Institute of arine Biobgy, Far East Branc of the USSR Academy of Sciences, at the request of the SeycheIles Government. The Republic of the Seychelles Islands sought informari on the marine plane resources and productivity of benthic and planktonic corn Seychelles Bank. After discussing the program of w rrnent of Development of the Republic of the Seychelles Islands with the Deputy lvine Jandron, the following research objectives were established for the expedition: 1) To study the benthic marine biota and fouling processes of the Seychelles Islands, which represents a poorly investigated region of the Indian Ocean. 2) To provide the first analyses of the species composition of algal communities for several remote island groups (Farquhar Atoll, CBeeivy Atoll, Cosmoledo Atoll, hirantes Group) and to supplement previous knowledge on the algae of Aldabra Atoll, ah6 Island and Praslin Island. 3) To study the distribution of autotrophic organisms over the various reef systems and determine the depth ranges of algae, seagrasses and corals. 4) To evaluate the common algal and seagrass resources in the area of study, particularly species of commercial interest. 5) To estimate the production potential of the major producers of organic matter on Seychelles reefs; i.e., benthic macroalgae, seagrasses, reef building corals and phytoplankton. 6) To assess the prevalent environmental parameters of the various island groups studied: e.g., optical characteristics of the water, seawater temperatures, nutrient contents, oxygen levels, pH and current velocities. -
