Dave Clarke, Craig Walker and Paul Atkin Invertebrate Conservation Centre, Zoological Society of London. Regent's Park. London NW1 4RY, UK Abstract Pearce-Kelly, P., Clarke, D., Walker, C. and Atkin, P., 1 997. A conservation programme for - the partulid tree snails of the Pacific region. Memoirs ofthe Museum of Victoria 56(2): 43 1 433. Throughout the Pacific numerous endemic mollusc species have either become extinct in the wild or are currently facing the threat of extinction as a result of introduction of the predatory snail Euglandina rosea and the New Guinea flatworm Platyclemus manokwari. Without determined conservation efforts, including the establishment of ex situ breeding programmes, much of the region's endemic snail fauna will be lost. Since 1986 a collabor- ative international conservation programme has been in place for partulid tree snails. The participating institutions currently maintain a total of 33 taxa in culture (comprising > 12 000 snails). The conservation status of all 1 17 partulid species has been assessed usingthe Conservation Action Management Plan (CAMP) process. Target ex situ population sizes required to maintain 90% of starting heterozygosity over 100 years have been calculated using the analytical model programme CAPACITY (Pearce-Kelly et al., 1994) The genetic management requirements of the breeding programme have necessitated the development of a colony management computer database enabling demographic management and analy- sis of the populations. -

EENY-494 Terrestrial Slugs of Florida (Gastropoda: Stylommatophora)1 John L. Capinera2 Introduction Florida has only a few terrestrial slug species that are native (indigenous), but some non-native (nonindigenous) species have successfully established here. Many interceptions of slugs are made by quarantine inspectors (Robinson 1999), including species not yet found in the United States or restricted to areas of North America other than Florida. In addition to the many potential invasive slugs originating in temperate climates such as Europe, the traditional source of invasive molluscs for the US, Florida is also quite susceptible to invasion by slugs from warmer climates. Indeed, most of the invaders that have established here are warm-weather or tropical species. Following is a discus- sion of the situation in Florida, including problems with Figure 1.

When closed, the pore can be difficult to locate. slug identification and taxonomy, as well as the behavior, Note that there are two pairs of tentacles, with the larger, upper pair ecology, and management of slugs. bearing visual organs.

Slugs also reduce water loss by opening their internal shell and a few have a greatly reduced external breathing pore (pneumostome) only periodically instead of shell). The slug life-form (with a reduced or invisible shell) having it open continuously. Slugs produce mucus (slime), has evolved a number of times in different snail families, which allows them to adhere to the substrate and provides but this shell-free body form has imparted similar behavior some protection against abrasion, but some mucus also and physiology in all species of slugs. -

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. -
CAPS PRA: Achatina Fulica 1 Mini Risk
Mini Risk Assessment Giant African Snail, Achatina fulica Bowdich [Gastropoda: Achatinidae] Robert C. Venette & Margaret Larson Department of Entomology, University of Minnesota St. Paul, MN 55108 September 29, 2004 Introduction The giant African snail, Achatina fulica, occurs in a large number of countries around the world, but all of the countries in which it is established have tropical climates with warm, mild year-round temperatures and high humidity. The snail has been introduced purposefully and accidentally to many parts of the world for medicinal purposes, food (escargot), and for research purposes (Raut and Barker 2002). In many instances, the snail has escaped cultivation and established reproductive populations in the wild. In Florida and Queensland, established populations were eradicated (Raut and Barker 2002). Where it occurs, the snail has the potential to be a significant pest of agricultural crops. It is also an intermediate host for several animal pathogens. As a result, this species has been listed as one of the 100 worst invasive species in the world. Figure 1. Giant African Snail (Image courtesy of USDA-APHIS). Established populations of Achatina fulica are not known to occur in the United States (Robinson 2002). Because of its broad host range and geographic distribution, A. fulica has the potential to become established in the US if accidentally or intentionally introduced. This document evaluates several factors that influence the degree of risk posed by A. fulica and applies this information to the refinement of sampling and detection programs. 1. Ecological Suitability. Rating: Low “Achatina fulica is believed to have originally inhabited eastern coastal Africa. -

The malacological collection of the Universidade Federal de Santa Maria, curated by Dr. Carla B. Kotzian, has been recently donated to the Museu de Zoologia da Universidade de São Paulo (MZSP, Brazil). The collection is rich in well preserved specimens of terrestrial gastropods from central Rio Grande do Sul state, in southernmost Brazil. That region, centered in the municipality of Santa Maria, represents a transitional area between the Atlantic Rainforest and Pampas biomes and has been scarcely reported in the literature. Therefore, we present a taxonomical study of these specimens, complemented by historical material of the MZSP collection. Overall, we report 20 species, mostly belonging to the Stylommatophora, from which four represent new records for Rio Grande do Sul: Adelopoma brasiliense, Happia vitrina, Macrodontes gargantua, and Cyclodontina corderoi. The present report of C. corderoi is also the first from Brazil. Two introduced species were found in the studied material: Bradybaena similaris and Zonitoides sp. Key-Words.

Morphometric Identification of Two Species of Achatinidae :Achatina Achatina Linné, 1758 Et Archachatinaventricosa Gould, 1850

To achieve this, measurements were made on different parts of the shell of the snails concerned and reports were made notified. Values show that i) the Right side length (LD) and Left side length (LG) obtained in the species A. achatina are statistically higher than those measured in the species Arch. ventricosa, while the measured high side lengths (LH) are statistically identical; ii) The length of the large diameter (LGD) in A. achatina is statistically higher than that of Arch. ventricosa; iii) total shell length (LT) and length Apex-Last suture (LAp-DS) in A. achatina are statistically higher than those of Arch. ventricosa.These results justify the fact that (i) the shell of the species A. achatina is longer than that of the species Arch. ventricosa ; ii) the shell opening of the species Arch.
