Sebastian). Students graduated: Hayes will graduate (PhD Zoology) in 2009, his dissertation research based partly on the project. CHANGES IN CONDITIONS The project has developed basic use of molecular phylogenetic techniques for identification of otherwise difficult to identify pest species. 72nd Annual Meeting of the American Malacological Society, Seattle, 26-30 June 2005 [best student paper award] Hayes, K.A. endobj Applesnails are larger than most freshwater snails and can be separated from other freshwater species by their oval shell which has the umbilicus (the axially aligned, hollow, cone-shaped space within the whorls of a coiled mollusc shell) of the shell perforated or broadly open. Description: Freshwater snail with a rounded, yellowish to ��� Our helpful friend Peter Topley at the Conchological Society (that���s a posh word for the study of molluscs), has produced a 1-page Snail and Slug Identification ��� Also collaboration with scientists throughout S. and C. America to obtain material from as wide a range as possible. Apple snail is a general name for freshwater snails that you���d find in pet stores for freshwater aquariums. Molluscan models in evolutionary biology: apple snails (Gastropoda: Ampullariidae) as a system for addressing fundamental questions. Translucent shells (see below) may be very pale when empty but nearly black with the animal showing through the shell. Golden apple snails are tremendously serious global invasive pests originated from South America. 2005. Lai, P.-Y., Chang, Y.F. These peaceful snails live 3 to 4 years, grow to a little over 1½ inch in diameter and are valued for their bright colors and algae eating ability. Additional samples were obtained from collaborators in south-east Asia. Applesnails are larger than most freshwater snails and can be separated from other freshwater species by their oval shell which has the umbilicus (the axially aligned, hollow, cone-shaped space within the whorls of a coiled mollusc shell) of the shell perforated or broadly open. Data or databases: ��� Apple snails are often sold under the name "golden (ivory, blue, black...) mystery snail" and they are ��� The other widespread species in south-east Asia is Pomacea insularum, the same species that is found in Texas, Florida and Georgia and that was previously incorrectly identified as P. canaliculata. The undergraduate who did his research in association with the project graduated (BS Biology) in 2007. Many invasive apple snails have been mistakenly identified as P. canaliculata since their introduction to ��� Out of South America: multiple origins of non-native apple snails in Asia. (9 - Brasil); Pomacea sp. These species can be distinguished genetically but many cannot be distinguished on gross morphology. The other species in south-east Asia is Pomacea insularum, the same species that is found in Texas, Florida and Georgia and & Cowie, R.H. VI Latin American Malacological Congress, Panama, 4-7 July 2005 [invited] Hayes, K.A. Most of the focus has been on the COI and 16S mitochondrial markers, with a lesser focus on the H3 nuclear marker. <> Shell color varies from yellow to brownish black with or without dark spiral bands. Apple snail is capable to get oxygen both from atmospheric air and from water. <> 30th Annual Tester Memorial Symposium, University of Hawaii, 16-18 March 2005 SERVICES University of Hawaii undergraduate trained in molecular phylogenetics and undertook a research project supervised by Cowie/Hayes to characterize Hawaiian apple snails genetically. Distribution of the invasive apple snail Pomacea canaliculata (Lamarck) in the Hawaiian Islands (Gastropoda: Ampullariidae). Came from the river Amazon where it inhabits all along the river. We expect similar interest in the papers on the species in SE Asia and Hawaii. 11 0 obj In: Proceedings - APEC symposium on the management of the golden apple snail, September 6-11, 2004 (eds. Apple Snails are often refered to as "Blue Mystery Snails" in the pet store, with little regard or information about their species. BACKGROUND. Operculum. Questions about apple snails, notably identification, often received from around the world and responded to. Such variation creates confusion in identification, leading in this case to over a hundred synonymies for this species and the moniker as the ��� endobj Though not everyone���s favourites, especially gardeners, you can easily find a variety of snails and slugs munching on your home���s plants.
