  • The Relationships Between Length and Weight of the Aldabra Giant Tortoise, Dipsochelys Dussumieri, in Mauritius
    The relationships between length and weight of the Aldabra giant tortoise, Dipsochelys dussumieri, in Mauritius L. Aworer & R. Ramchurn* *Faculty of Agriculture, University of Mauritius, Réduit, MAURITIUS [[email protected] / [email protected]] Abstract: In the Republic of Mauritius Aldabra giant tortoises, Dipsochelys dussumieri (also known as Geo- chelone gigantea), are kept in captivity mainly in private parks, public gardens, a few sugar estates and by some people as pets . The study was carried out in two private parks: Casela and La Vanille and two public gardens, SSR Botanical Garden at Pamplemousses and Balfour Garden. The private parks were better managed and maintained by virtue of their commercial purpose. Improvements were needed for Balfour Garden. Regressions were established between straight, curved carapace lengths and weight of juveniles, adults, both males and females. Regressions for adult males and females were compared using two different methods (straight and curved carapace lengths). A strong positive relationship was observed between the weight and straight carapace length of juveniles (R2=0.96) and adult males (R2=0.88), whereas, for adult females there was a weaker relationship (R2=0.69). The same coefficient of regression was observed when the curved carapace length was regressed with weights for juveniles. A strong positive relationship was observed between weight and curved carapace length of adult males (R2=0.94), and for adult females there was a positive relationship (R2=0.74). From the work carried out, it had been found that both methods could be used to estimate weights of the tortoises using their respective equations. The equation for straight carapace length was Log Y = 2.47Log X + 0.2 (Y = weight in grammes; X = length in cm).

    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.

  • ALDABRA GIANT TORTOISE Aldabrachelys Gigantea
    ALDABRA GIANT TORTOISE Aldabrachelys gigantea Location: The Aldabra giant tortoise inhabits the Aldabra Islands, a coral atoll comprised of 4 islands in the Seychelles, which is located between the coast of Kenya and the northern tip of Madagascar. The Aldabra giant tortoise occurs in many different habitats. The largest tortoise concentrations are found on the grasslands called platins; the grasslands are often dotted with trees and bushes. It also frequents scrublands, mangrove swamps and coastal dunes. Diet: These animals are primarily herbivores with the ability to both graze and browse. In the drier areas, they graze mostly on sedges, and a combination of native species of grasses and herbs. Many of these distinct plants are naturally dwarfed and grow their seeds not from the tops of the plants, but closer to the ground to avoid the tortoises’ close cropping jaws. In the wooded and scrub areas, tortoises browse on many types of woody plants. A number of species are readily eaten, and some show a conspicuous browse line about 3 feet above the ground, which is about as high as the tortoises can stretch their necks. Life Cycle: Aldabra giant tortoises are found both individually and in herds. They mainly feed in the mornings and continue until the temperature becomes too hot. Sheltering trees or bushes are necessary to escape the extreme mid- day sun; some tortoises cool themselves in pools or mud holes. Mating of Aldabra giant tortoises usually occurs between February and May. The eggs are carried within the female’s body for about 2.5 months. During the dry season, the female digs a flask-shaped cavity where she deposits her eggs.

  • ON the NATIVE FAUNA of ALDABRA ATOLL, SEYCHELLES Ferai Cats
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by I-Revues THE IMPACT OF THE FERAL CAT (FELIS CATUS) ON THE NATIVE FAUNA OF ALDABRA ATOLL, SEYCHELLES Wendy SEABROOK* Ferai cats (Fe lis catus) have colonized and caused considerable damage to island ecosystems throughout the world (Merton, 1978 ; Croxall et al., 1984 ; Veitch, 1985). In this paper the results of an examination (1985-86) of the distribution and ecology of the ferai cat on Aldabra Atoll in the Indian Ocean (9.5" S., 46.5" E.) are summarized, and the impact of cats on native fauna is assessed. Prior to this study very little was known about the cat population. Only sightings and signs of them had been reported on the four main islands of the Atoll (Stoddart, 1971 ; Racey Nicoll, 1984). Considering Aldabra's status as a World Heritage Site and its rich endemie fauna (eg. Giant tortoise (Geochelone& gigantea) and White-throated rail ( Dryo­ limnas cuvieri aldabranus)), a preliminary ecological study on the cats was necessary to design an eradication or control programme. Any proposai to eliminate an alien predator from an island should be justified on biological grounds, and the likely ecological consequences must be considered (Merton, 1978), especially if, as on Aldabra, other alien predators are also present. Because of the considerable financial investment and persan-power required, eradication and control programmes must also be evaluated with reference to other mana­ gement objectives. Aldabra is one of the finest examples in the world of a raised coral atoll ecosystem (Stoddart Savy, 1983).

    Getting to Know the Locals August 29, 2017, Seychelles, Desroches Island The Aldabra giant tortoise (Aldabrachelys gigantea) is unique to Seychelles. When humans first arrived in the Western Indian Ocean there were at least nine species of giant tortoises living on islands in the region (five in the Mascarenes, two on Madagascar, and two in Seychelles). In Seychelles, there were giant tortoises living on the granitic (inner) islands and also in the remote southern Aldabra group of islands. Sadly, humans drove them all to extinction, except for those living on Aldabra Atoll, which is the most remote island group in the Seychelles; but even at Aldabra, the tortoise population was much reduced by the late 19th century. Tortoises did not naturally occur in the Amirantes group of islands when Europeans discovered the islands in the 16th century. This is probably because the Amirantes are young sand cay islands that emerged above sea level only about 4,000 years earlier. So, a breeding colony of Aldabra giant tortoises was established on Desroches, comprising individuals from the Aldabra population. 1 The giant tortoises on Desroches are under the care of the Island Conservation Society (ICS), which oversees the running of the tortoise breeding program and works to ensure the well-being of the entire Desroches population, which includes more than 150 animals. While staying at Four Seasons Resort Seychelles at Desroches Island, guests are encouraged to visit the Tortoise Sanctuary, where they can learn more about their habits and way of life. For example: • An Aldabra giant tortoise drinks through its nose.

Oooh man I was right! The trip started in paradisiacal surroundings on the island of Mahe, the largest of all islands that together form the Seychelles. Before embarking the Silver Discoverer , we planned some pre-tour birding. In the afternoon we made an outing to find the rare Seychelles White-eye, Seychelles Blue-Pigeon, and Seychelles Sunbird. Rapidly they were found, and good looks were enjoyed by all. In the evening after dinner we went out for probably the rarest and most difficult bird of the entire tour, the Seychelles Scops-Owl. For a long time we heard no response, but just before we decided to leave the designated spot we heard one quick rasping call. Soon after, we found the bird in full delight—just amazing! The enchanting Seychelles Sunbird has a very restricted range (photo M.Valkenburg) Our journey would take us from several Seychellois islands to Madagascar, visiting the world-famous Aldabra Atoll on the way, ending the trip with visits to Reunion and Mauritius. This adventure was one-of- a-kind, with our program visiting so many difficult to reach places where we had the chance of finding many of the world’s most hard-to-get endangered species.

  • Environmental Impact Assessment: Proposal to Return Giant Tortoises to Madagascar to Conserve Threatened Forests
    Environmental Impact Assessment: Proposal to return giant tortoises to Madagascar to conserve threatened forests Hume Julian Submitted by Biodiversity Conservation Madagascar April 2016 EIA: Tortoise reintroduction to Beanka April 2016 Summary Madagascar’s fragile ecosystems have been severely degraded and the future survival of some species and ecosystems appears bleak, despite concerted conservation efforts. The extinction of key species has upset the ecological balance and left remnant ecosystems and their inhabitants poorly adapted to future pressures such as habitat destruction, fire, climate change and invasive species. Restoring the large grazers and seed dispersers which once created and maintained Madagascar’s ecosystems and their inhabitants is vital for their future persistence. In this document, we propose to reintroduce a surviving lineage of one of the Madagascan giant tortoises to Beanka Protected Area in western Madagascar. Reintroducing giant tortoises has shown to be a low-cost, landscape based approach to conserving endemic forests which are threatened by annual wildfires. We, Biodiversity Conservation Madagascar, La Vanille Nature Park and Bioculture (Mauritius) Ltd, believe that this innovative approach to aiding in the long- term restoration of threatened habitats will attract global attention and provide a useful framework for managing similarly threatened habitats across Madagascar. The purpose of this document is to explain the project and to provide an environmental impact assessment of the reintroduction evaluating any potential risk and how these can be mitigated. 1 EIA: Tortoise reintroduction to Beanka April 2016 Introduction The richness and spectacular array of Madagascar’s native wildlife is just a fraction of what once resided on the island.
