Snail Herbivory Decreases Cyanobacterial Abundance And
Snail herbivory decreases cyanobacterial abundance and lichen diversity along cracks of limestone pavements 1 2, 2 2 LARS FRO€BERG, PETER STOLL, ANETTE BAUR, AND BRUNO BAUR 1Botanical Museum, Department of Biology, O¨ stra Vallgatan 18, SE-223 61 Lund, Sweden 2Section of Conservation Biology, Department of Environmental Sciences, University of Basel, St. Johanns-Vorstadt 10, CH-4056 Basel, Switzerland Abstract. Herbivores are known to decrease plant species diversity in ecosystems with low productivity. Limestone pavements are low-productive habitats harboring specialized communities of cyanobacteria, and endo- and epilithic lichens exposed to extreme temperature and humidity fluctuations. Pavements of the Great Alvar (O¨ land, Sweden) are covered by free-living cyanobacteria giving the rock surface a dark color. Based on cyanobacterial abundance along the edges, two types of cracks intersecting the pavements have been described: Type one with abundant cyanobacteria and type two without cyanobacteria resulting in light-colored edges. Erosion and different lengths of inundation by melt water have been suggested to cause the conspicuous differences in community composition and hence color between cracks. We hypothesized that this pattern results from the grazing activity of the cyanobacteria- and lichen-feeding snail Chondrina clienta, which reduces cyanobacterial cover along light-colored cracks and facilitates endolithic lichens. Three dark and three light-colored cracks were investigated at each of three localities. Crack characteristics (i.e., aspect, width, depth and erosion) and snail density were assessed at the crack level. Cyanobacterial cover and lichen diversity were recorded in 1-cm sections, sampled every 5 cm along eight 160-cm-long transects per crack. -

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). -
The Assimineidae of the Atlantic-Mediterranean Seashores
B72(4-6)_totaal-backup_corr:Basteria-basis.qxd 15-9-2008 10:35 Pagina 165 BASTERIA, 72: 165-181, 2008 The Assimineidae of the Atlantic-Mediterranean seashores J.J. VAN AARTSEN National Museum of Natural History, P.O.Box 9517, 2300 RA Leiden, The Netherlands. A study of the Atlantic – and Mediterranean marine species of the genera Assiminea and Paludinella revealed several new species. The species Assiminea gittenbergeri spec. nov. is estab- lished in the Mediterranean. Assiminea avilai spec. nov. and Assiminea rolani spec. nov. have been found in Terceira, Azores and in Madeira respectively. A species from the Atlantic coast of France, cited as Assiminea eliae Paladilhe, 1875 by Thiele, is described as Paludinella glaubrechti spec. nov. A. eliae cannot be identified today as no type material is known. The name , howev- er, is used for several different species as documented herein. Assiminea ostiorum (Bavay, 1920) is here considered a species in its own right. Paludinella sicana ( Brugnone, 1876), until now con- sidered an exclusively Mediterranean species, has been detected along the Atlantic coast at Laredo ( Spain) in the north as well as at Agadir ( Morocco) in the south. Keywords: Gastropoda, Caenogastropoda, Assimineidae, Assiminea, Paludinella, systematics, Atlantic Ocean east coast, Mediterranean. INTRODUCTION The Assimineidae H. & A. Adams, 1856 are a group of mollusks living worldwide in brackish water, in freshwater as well as terrestrial habitats. In Europe there are only a few species known. They live in usually more or less brackish conditions high in the tidal zone, frequently along tidal mudflats. The two genera recognized to date are Paludinella Pfeiffer, 1841 with Paludinella littorina (Delle Chiaje, 1828) and Paludinella sicana (Brugnone, 1876) and the type-genus Assiminea Leach in Fleming, 1828, with the type- species Assiminea grayana (Fleming, 1828) as well as Assiminea eliae Paladilhe, 1875. -

Av. Diagonal 645, 08028 Barcelona. E-mail: [email protected] Resumen.—Lista actualizada de los opistobranquios (Mollusca: Gastropoda: Opisthobranchia) de las costas catalanas. Se presenta una lista taxonómica de las especies de opistobranquios (Mollusca: Gastropoda: Opisthobranchia) registradas hasta el presente en aguas litorales o de profundidad de las costas catalanas (NE Península Ibérica). Esta lista se basa en citas publicadas en la literatura, en citas fotográficas procedentes de Internet, en comunicaciones personales de buceadores y en numerosos datos inéditos de recolecciones del autor. De cada especie se indican las referencias bibliográficas, y en el caso de los datos no publicados o procedentes de Internet, se indican las localidades concretas donde se han recolectado u observado. En aguas catalanas se registran hasta el momento un total de 205 especies de opistobranquios: 36 de Cephalaspidea s.s., 9 de Architectibranchia, 7 de Anaspidea, 11 de Thecosomata, 3 de Gymnosomata, 14 de Sacoglossa, 2 de Umbraculacea, 8 de Pleurobranchacea y 115 de Nudibranchia (55 Doridina, 14 Dendronotina, 4 Arminina y 42 Aeolidina). De estas especies, tres de ellas se citan por vez primera para el litoral ibérico (Runcina adriatica, R. brenkoae y Tritonia lineata), mientras que otras siete más no habían sido recolectadas en el litoral catalán (Runcina coronata, R. ferruginea, Elysia translucens, Ercolania coerulea, Berthellina edwarsi, Doris ocelligera y Piseinotecus gabinieri).
