  • Land Molluscan Fauna of the Dongsha Island with Twenty New Recorded Species
    Taiwania, 52(2): 145-151, 2007 Land Molluscan Fauna of the Dongsha Island with Twenty New Recorded Species Shu-Ping Wu(1), Chung-Chi Hwang(2), Hui-Ming Huang(3), Hsueh-Wen Chang(4), Yao-Sung Lin(1,5) and Pei-Fen Lee(1,5,6) (Manuscript received 19 October, 2006; accepted 10 February, 2007) ABSTRACT: A thorough field survey concerning the land molluscan fauna of the Dongsha Island in the South China Sea was conducted in summer and fall, 2006. Twenty-six species belonging to thirteen families of land snail were recorded. Of these, 20 species and four families are new records. Emendations of five species from the previous records were also made. Alive adults along with juvenile individuals were collected in most of the species. Since no endemic land snail species was found, we proposed that the plausible origin of these land snails might have dispersed from adjacent localities or via artificial introduction. KEY WORDS: Land molluscan fauna, Pratas Island, Taiwan, South China Sea, New recorded species. INTRODUCTION Ministry of the Interior. In particular, we conducted a thorough inventory on the land molluscan fauna in The Dongsha (Pratas) Island is situated at the the Dongsha Island and studied the distribution and western side of the Dongsha reef atoll and is the taxonomy of these species. We also discussed the largest island in the South China Sea. The atoll has a origin, dispersal pathway and biogeography of the reputation for abundance in fishery resources (Su et snails. al., 1976; Lu and Shieh, 1981). There are several natural resources inventory conducted in the island MATERIALS AND METHODS and adjacent waters (Chang et al., 1995; Chen et al., 1991; Chiang, 1975; Huang et al., 1994; Jeng et al., Study Area 2005; Severinghaus et al., 2005).

Goals of the Belau Land Snail Project The goals of this project were twofold. The overarching goal of this project was to provide the Republic of Belau, local conservation agencies and state governors with an up-to-date assessment of the land snail species found within Belau’s many islands. Understanding what species are present and where is a vital first step for guiding all future management decisions. Through my collaboration with the Palau Conservation Society my aim is to continue this survey work, thereby increasing our knowledge (and indeed, the world’s knowledge) of this spectacular land snail fauna. The second goal of the project was to collect data for my doctoral dissertation work at the University of Chicago (Chicago, Illinois U.S.A.), which focuses on the evolution and biogeography of Belau’s diplommatinid land snails.

Y. Low Abstract. An annotated checklist of the Mollusca from the Australian Indian Ocean Territories (IOT) of Christmas Island (Indian Ocean) and the Cocos (Keeling) Islands is presented. The checklist combines data from all previous studies and new material collected during the recent Christmas Island Expeditions organised by the Lee Kong Chian Natural History Museum (formerly the Raffles Museum of Biodiversty Resarch), Singapore. The checklist provides an overview of the diversity of the malacofauna occurring in the Cocos (Keeling) / Christmas Island ecoregion. A total of 1,178 species representing 165 families are documented, with 760 (in 130 families) and 757 (in 126 families) species recorded from Christmas Island and the Cocos (Keeling) Islands, respectively. Forty-five species (or 3.8%) of these species are endemic to the Australian IOT. Fifty-seven molluscan records for this ecoregion are herein published for the first time. We also briefly discuss historical patterns of discovery and endemism in the malacofauna of the Australian IOT. Key words.

  • Prosobranch Gastropods of Guam
    Micronesica 35-36:244-270. 2003 Prosobranch gastropods of Guam BARRY D. SMITH Marine Laboratory University of Guam Mangilao, Guam 96923 U.S.A. email: [email protected] Abstract—Based on records from invertebrate collections at the University of Guam, specimens cataloged at other institutions, and the published literature, there are 895 species of prosobranch gastropods from Guam. The vast majority of the species are marine, but terrestrial and aquatic prosobranchs are included. Most the species recorded to date are conspicuous, epibenthic species from shallow reef habitats, but some species have been taken from depths up to 400 m. Microgastropods less than 7 mm in size have been poorly investigated to date. Comparison of prosobranch gastropods from Guam and Enewetak reveal that some 56% of the species occurring at Enewetak are found in Guam. Introduction Molluscs have been collected in Guam since the arrival of the earliest inhabitants (Thompson, 1945). Despite the long history of European contact with the island, scant attention was given to systematic investigation of the fauna until the collections of Quoy and Gaimard (1824–1826; 1830–1834). Hidalgo (1904– 1905) was the first to produce a catalog that included molluscs from Guam, but his emphasis was mostly on the Philippine Islands fauna. This catalog was followed by a series of unpublished lists produced by shell collectors and shell club members during the last several decades. Synoptic collections of molluscs from Guam and Micronesia were started by faculty of the University of Guam in the mid-1960s. These collections are housed in the Richard E. Dickinson Memorial Mollusc Collection at the University of Guam Marine Laboratory.

How do we treat them as intact voucher specimens? The shell of the whole individual in formalin or alcohol will corrode or fade. In order to dissect the soft parts, you must crack or dissolve the shell. Niku-nuki, a traditional method that has been used by Japanese malacologists overcomes this dilemma. It is also applicable to minute molluscs. The outline is: 1. Prepare boiling hot freshwater, a small beaker, forceps (with fi ne tips), a small syringe, a petri dish, and a stereomicroscope; 2. When the live animal in the beaker crawls on the bottom, pour boiling hot water over the animal, which is killed immediately. Some seconds later take the specimen out of the hot water, hold it with two fi ngers of one hand and hold the forceps with another hand; 3.

Many of the species are unique to the archipelago, or even to only one of the islands there. Sadly, much like the native terrestrial snail faunas across the tropical Pacific, the land snails of the Marianas are experiencing precipitous declines and extinctions due to the introduction of predators and loss of habitat.
