The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20%
The Slugs of Britain and Ireland: Undetected and Undescribed Species Increase a Well-Studied, Economically Important Fauna by More Than 20% Ben Rowson1*, Roy Anderson2, James A. Turner1, William O. C. Symondson3 1 National Museum of Wales, Cardiff, Wales, United Kingdom, 2 Conchological Society of Great Britain & Ireland, Belfast, Northern Ireland, United Kingdom, 3 Cardiff School of Biosciences, Cardiff University, Cardiff, Wales, United Kingdom Abstract The slugs of Britain and Ireland form a well-studied fauna of economic importance. They include many widespread European species that are introduced elsewhere (at least half of the 36 currently recorded British species are established in North America, for example). To test the contention that the British and Irish fauna consists of 36 species, and to verify the identity of each, a species delimitation study was conducted based on a geographically wide survey. Comparisons between mitochondrial DNA (COI, 16S), nuclear DNA (ITS-1) and morphology were investigated with reference to interspecific hybridisation. Species delimitation of the fauna produced a primary species hypothesis of 47 putative species. This was refined to a secondary species hypothesis of 44 species by integration with morphological and other data. Thirty six of these correspond to the known fauna (two species in Arion subgenus Carinarion were scarcely distinct and Arion (Mesarion) subfuscus consisted of two near-cryptic species). However, by the same criteria a further eight previously undetected species (22% of the fauna) are established in Britain and/or Ireland. Although overlooked, none are strictly morphologically cryptic, and some appear previously undescribed. Most of the additional species are probably accidentally introduced, and several are already widespread in Britain and Ireland (and thus perhaps elsewhere). -
On the Distribution and Food Preferences of Arion Subfuscus (Draparnaud, 1805)
Vol. 16(2): 61–67 ON THE DISTRIBUTION AND FOOD PREFERENCES OF ARION SUBFUSCUS (DRAPARNAUD, 1805) JAN KOZ£OWSKI Institute of Plant Protection, National Research Institute, W³adys³awa Wêgorka 20, 60-318 Poznañ, Poland (e-mail: [email protected]) ABSTRACT: In recent years Arion subfuscus (Drap.) is increasingly often observed in agricultural crops. Its abun- dance and effect on winter oilseed rape crops were studied. Its abundance was found to be much lower than that of Deroceras reticulatum (O. F. Müll.). Preferences of A. subfuscus to oilseed rape and 19 other herbaceous plants were determined based on multiple choice tests in the laboratory. Indices of acceptance (A.I.), palat- ability (P.I.) and consumption (C.I.) were calculated for the studied plant species; accepted and not accepted plant species were identified. A. subfuscus was found to prefer seedlings of Brassica napus, while Chelidonium maius, Euphorbia helioscopia and Plantago lanceolata were not accepted. KEY WORDS: Arion subfuscus, abundance, oilseed rape seedlings, herbaceous plants, acceptance of plants INTRODUCTION Pulmonate slugs are seroius pests of plants culti- common (RIEDEL 1988, WIKTOR 2004).

ABSTRACT OF THESIS IMPACT OF DIETARY DIVERSIFICATION ON INVASIVE SLUGS AND BIOLOGICAL CONTROL WITH NOTES ON SLUG SPECIES OF KENTUCKY Increasing introductions of non-native terrestrial slugs (Mollusca: Gastropoda) are a concern to North American regulatory agencies as these generalists impact the yield and reduce the aesthetic value of crop plants. Understanding how the increase in diversification in North American cropping systems affects non-native gastropods and finding effective biological control options are imperative for pest management; however, little research has been done in this area. This study tested the hypothesis that dietary diversification affects the biological control capacity of a generalist predator and allows the slug pest Deroceras reticulatum (Müller) (Stylommatophora: Agriolimacidae) to more effectively fulfill its nutritional requirements. -

Bollettino Malacologico, Roma, 39 (9-12): 203-206, [2003] 2004 - Società Italiana di Malacologia New records of Testacella (Gastropoda, Pulmonata, Testacellidae) from Abruzzo and Sardinia, Italy Andrea C. Rinaldi KEYWORDS: terrestrial molluscs, slugs, distribution, conservation, Abruzzo, Sardinia. ABSTRACT Testacella (Gastropoda, Pulmonata, Stylommatophora) is the only genus of the family Testacellidae, a small group of slugs characterised by a reduced, auriform shell situated at the posterior end of the body. In Italy, three species are present. Due in part to their largely subterranean lifestyle, records of these molluscs are relatively rare, and modern (post 1950) data on their local occurrence and distribution are limited to only few regions. We here report the recent finding of Testacella scutulum in Abruzzo and T. gestroi in south-eastern Sardinia, respectively. This is the first record of Testacella from Abruzzo, whereas T. gestroi was found in an area adjacent to the type locality for the species, described in 1873, confirming the survival to date of this population. In consideration of the value of Testacella from a biogeographical point of view, and of the scanty information currently available on the size and distribution of populations and on their conservation status, further research on these molluscs is auspicable. RIASSUNTO Testacella (gastropoda, pulmonata, stylommatophora), unico genere della famiglia Testacellidae, comprende poche specie di molluschi terrestri limaciformi, carnivori (in genere si nutrono di lombrichi ma occasionalmente anche altri molluschi terrestri), che presentano una piccola conchiglia auriculiforme, esterna, situata nella parte finale del corpo. In italia vivono solo tre specie ma, in parte a causa dello stile di vita sotterraneo, le segnalazioni relative a questi molluschi sono estremamente rare, tanto che dati ‘moderni’ (post 1950) relativi alla loro presenza e distribuzione sono limitati a poche regioni. -

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. -

Slugs: a Guide to the Invasive and Native Fauna of California ANR Publication 8336 2
University of California Division of Agriculture and Natural Resources http://anrcatalog.ucdavis.edu Publication 8336 • January 2009 SLUGA Guide to the InvasiveS and Native Fauna of California RORY J. MC DONNELL, Department of Entomology, University of California, Riverside; TimOTHY D. PAINE, Department of Entomology, University of California, Riverside; and MICHAEL J. GOrmALLY, Applied Ecology Unit, Centre for Environmental Science, National University of Ireland, Galway, Ireland Introduction Slugs have long been regarded worldwide as severe pests of agricultural and horticultural production, attacking a vast array of crops (reviewed by South [1992] and Godan [1983]). Species such as Deroceras reticulatum (Müller1), Arion hortensis d’Audebard de Férussac, and Tandonia budapestensis (Hazay) are among the most pestiferous (South 1992) and have increased their ranges as humans have continued their colonization of the planet. Slugs have also been implicated in the transmission of many plant pathogens, such as Alternaria brassicicola Schw., the causal agent of brassica dark leaf spot (Hasan and Vago 1966). In addition, they have been implicated as vectors of Angiostrongylus cantonensis (Chen), which can cause the potentially lethal eosinophilic meningo-encephalitis in humans (Aguiar, Morera, and Pascual 1981; Lindo et al. 2004) and Angiostrongylus costaricensis Morera and Céspedes, which causes abdominal angiostrongyliasis (South 1992). Recent evidence also indicates that slugs vector Campylobacter spp. and Escherichia coli (Migula), which cause food poisoning and may have been partially responsible for recent, highly publicized massive recalls of contaminated spinach and other salad crops grown in California (Raloff 2007, Sproston et al. 2006). 1Slug taxonomy follows Anderson (2005) throughout.
