Mollusca) from Malta
The Central Mediterranean Naturalist 4 (1): 35 - 40 Malta: December 2003 ON SOME ALIEN TERRESTRIAL AND FRESHWATER GASTROPODS (MOLLUSCA) FROM MALTA Constantine Mifsud!, Paul Sammut2 and Charles Cachia3 ABSTRACT Nine species of gastropod molluscs: Otala lactea (0. F. MUller, 1774); Cemuella virgata (da Costa, 1778); Cochlicella barbara (Linnaeus, 1758); Oxychilus helveticus (Blum, 1881); Succinea putris (Linnaeus, 1758); Oxyloma elegans (Risso, 1826); Helisoma duryi Wetherby, 1879; Planorbarius comeus (Linnaeus, 1758); and the limacid slug Lehmannia valentiana (A. Ferussac, 1822) are recorded for the first time as alien species from local plant nurseries. For each species a short description and notes on distribution and ecology are given. INTRODUCTION The land and fresh water Mollusca of the Maltese Islands have been recently well treated by Giusti et al. (1995). However, during the last twelve years many non-indigenous plants, shrubs and trees, both decorative species and fruit trees, have been imported from Europe either to embellish local gardens or roadsides or for agricultural purposes. It occurred to the authors that there is the possibility that alien species of molluscs might have been introduced accidentally with these imported plants. This is not a completely new phenomenon. For example, Pomatias elegans and Discus rotundatus occur at San Anton Gardens were they were probably alien introductions due to human activities (Thake, 1973). During recent research to assess the status of some of the endemic molluscs of the Maltese Islands, with special emphasis on the Limacidae, areas where imported plants are stocked were searched for any alien species. This resulted in the discovery of several alien species of terrestrial and freshwater snails, a few of them alive. -

Land Gastropods (Snail & Slugs) of Los Angeles
Land gastropods (snails & slugs) of Los Angeles County Why snails? • Many local species are endemic to Southern California • In fact, land snails are highly endemic around the world. • They evolve adaptations to relatively small locations. • Habitat destruction has put many land snails at high risk of extinction, including almost all of the endemic species in Southern California. Papustyla pulcherrima Manus Green Tree Snail Found: Manus Island, Papua New Guinea Facts: green color is natural but is only in outer protein layer of shell Lifestyle: tree snail, lives in island rainforests Conservation status: Endangered due to over-collection by humans and habitat (native tree) loss from logging Achatinella fulgens O`ahu tree snail Found: O`ahu, Hawaii Facts: sinestral (left-coiling), 41 species, 30 species extinct Lifestyle: tree snail, eats fungus off tree leaves Conservation status: Critically endangered due to predation by rats, introduced snails, and habitat (native tree) loss Zonitoides arboreus S.L.I.M.E Snails & slugs Living Oxychilus sp. In Metropolitan Environments Goals of SLIME • Inventory of living snail species in Los Angeles County • Compare with Museum historical records • Note introductions and extinctions • Ask where and why do populations live where they do What role do snails play in the environment? Many snails are decomposers. Decomposers consume dead or dying leaves, wood, and fungus. Without snails and other decomposers it would take much longer for nutrients to cycle through the environment: that is, move from living things to the soil, then back into living things again. Which snails and slugs are considered pests? Why? Pest snails are those that cause damage to human-grown plants and/or are so abundant that they cause damage to human-created landscapes. -

Simple Summary: The superfamily Helicoidea is a large and diverse group of Eupulmonata. The su- perfamily has been the subject of several molecular and phylogenetic studies which greatly improved our knowledge on the evolutionary relationships and historical biogeography of many families. In contrast, the available karyological information on Helicoidea still results in an obscure general picture, lacking a homogeneous methodological approach and a consistent taxonomic record. Never- theless, the available karyological information highlights the occurrence of a significant chromosomal diversity in the superfamily in terms of chromosome number (varying from 2n = 40 to 2n = 62), Citation: Petraccioli, A.; Crovato, P.; chromosome morphology and the distribution of different karyological features among different Guarino, F.M.; Mezzasalma, M.; taxonomic groups. Here we performed a molecular and a comparative cytogenetic analysis on of Odierna, G.; Picariello, O.; Maio, N. -

The ratio of DDD to DDT stayed fai r1 y constant at approximately 3: 1. INTRODUCTION Terrestrial gastropods, as members of natural communities, have become increasingly ex posed to numerous synthetic pesticides. As non-target organisms of many of these chemicals, snails and slugs are able to accumulate and concentrate various insecticides without any noti ceable deleterious effect at concentrations equal to or higher than the concentrations in their physical environment. The organochlorine insecticide 1, 1, l-trichloro, 2, 2-bis (p-chlorophenyl) ethane (DDT), is one of the chemicals accumlated by many soil organisms, in c1 uding terrestrial gastropods. The information in the literature on the bioaccumulation and bioconcentration of DDT and of its degradation products DDD (1, I-dichloro, 2, 2-bis (p-chlorophenyl) ethane) and DDE (1 , l-dichloro, 2, 2-bis (p-chlorophenyl) ethylene) by terrestrial gastropods and other soil organisms has been revie\ved and summarized by Thompson (1973). -
