Article Reference An integrated modelling approach for the management of clam farming in coastal lagoons
The development of shellfish farming was analyzed with a coupled watershed and 3D biogeochemical model for the Sacca di Goro coastal lagoon (Northern Adriatic Sea, Italy). Sacca di Goro is the second site in Europe for the production of the Manila clam (Tapes philippinarum). Different scenarios were identified and analyzed, considering clam productivity under different environmental conditions, namely with and without macroalgal blooms. In addition, the influence of climatic variability - dry, average and wet years - was assessed. Model simulations indicated that macroalgal blooms have an important negative impact on clam productivity due to the risk of anoxia and subsequent clam mortality. Furthermore, simulation results evidenced that meteorological conditions also affect clam productivity, especially in a dry year due to a shortage of food supply. © 2007 Elsevier B.V.

Article Reference Annotated checklist of the rotifers (Phylum Rotifera), with notes on nomenclature, taxonomy and distribution
Phylum Rotifera comprises about 2030 known species classified in three main groups, the marine Seisonida (3 species), the Monogononta (1570 species) and the unique, exclusively parthenogenetic Bdelloidea with 461 clonal species. Here I present an annotated checklist of the taxon, giving the global distribution of the valid species. This checklist contains over 3,000 available names at the genus- and species-group level, including valid names and a non-comprehensive list of synonyms. A number of taxonomic and nomenclatural suggestions following from the review is presented. Suggestions include several new synonyms and two nomina nova: Dissotrocha kostei for Dissotrocha aculeata Koste, 1996 non Ehrenberg, 1838 (stat. nov., ex. Dissotrocha hertzogi aculeata) and Lepadella zigzag for Lepadella bractea Myers, 1934 non (Ehrenberg, 1838). This contribution also describes features of an on-line, global names database of the Rotifera, on which this checklist is based. Copyright © 2007 Magnolia Press.

Article Reference Note on a highly diverse rotifer assemblage (Rotifera: Monogononta) in a Laotian rice paddy and adjacent pond
During August 1999, the authors conducted a sampling campaign in the PDR Laos, in order to contribute to the chorology of rotifers in the region. Two samples, collected from a rice paddy and an adjacent pond near Vientiane, Laos, contained a total of 135 rotifer species including several that appear new to science or that warrant taxonomical or biogeographical comments. No new species can be named, but Cephalodella boettgeri KOSTE and Floscularia armata SEGERS are recorded for the second time ever after their description from South America, and Parencentrum lutetiae (HARRING and MYERS) and Polyarthra luminosa KUTIKOVA are new to Southeast Asia. This raises the number of rotifers recorded from Laos from 9 to 130. The diversity recorded is remarkable, especially when compared with that of similar habitats in the Thai part of the floodplain of River Mekong and its tributaries. Different agricultural practices may account for the difference in species richness. Similar highly diverse rotifer faunas are known to occur in natural, tropical and subtropical floodplain systems only. This accords with the view that rice paddies can be regarded as artificial wetlands or floodplain systems, which, if managed taking biodiversity concerns into account, may have a potential for the conservation of freshwater biodiversity. © 2007 Wiley-VCH Verlag GmbH & Co.

Article Reference Revision of the Cancellariidae (Mollusca, Neogastropoda, Cancellarioidea) of the eastern Atlantic (40°N-40°S) and the Mediterranean
The Cancellariidae living off the western African coast, the mid-Atlantic Islands and in the Mediterranean Sea are reviewed. Twenty species are studied: 3 Admetula, 1 Axelella, 2 Bivetiella, 4 Brocchinia, 1 Cancellaria s.l., 1 Nothoadmete, 1 Loxotaphrus, 2 Solatia, 1 Sveltia, 2 Tribia, and 2 Trigonostoma. Trigonostoma gofasi n. sp. is distinguished from the western African T. scala (Gmelin, 1791) n. comb, by its multispiral protoconch, wider umbilicus, smooth columellar callus, axial ribs on the sutural ramp not reaching the suture, and the absence of a siphonal fasciole; and from the central western American T. goniostoma (Sowerby, 1832) in its wider umbilicus, more deviated columella and in being less elongate. A species of Solatia which has previously been recognised as new, is not named due to lack of adequate material. The species name in the combination Voluta cancellata Linnaeus, 1767 is declared nomen protectum, making the senior name Murex scabriculus Linnaeus, 1758 invalid as nomen oblitum. A neotype is designated for Murex scala Gmelin, 1791. A lectotype is designated for Cancellaria minima Reeve, 1856, Cancellaria similu Sowerby, 1833, Voluta lyrata Brocchi, 1814, Cancellaria angasi Crosse, 1863 and Cancellaria rigida Sowerby, 1832; the latter name refers to a West African and not a West American species. Distribution data are updated, and relations to fossil taxa are indicated when applicable. The protoconchs of 17 species are figured; only the protoconch type of the bathyal species Brocchinia decapensis and Nothoadmete euthymei n. comb, remain unknown. Egg capsules attributed to one of the North West African Bivetiella species are figured. © Publications Scientifiques du Muséum national d'Histoire naturelle.

Article Reference Diversity of rotifer fauna from five coastal peat swamps on phuket island, southern Thailand
A total of 133 rotifer species was identified from five coastal peat swamps on Phuket Island. Of these, Dicranophoroides sp.A and Harringia rousseleti were new to Thailand. The most speciose genus was Lecane (30.82\%), followed by Lepadella (12.03\%). The highest species richness occurred in Jae-Son (100 species), followed byJik (84 species), Jood (67 species), Mai-Khao (65 species) and Sra-Boua (48 species), respectively. One hundred and ninety-three rotifer species are now known from peat swamps in Thailand.

Article Reference Octet Stream Ant biodiversity conservation in Belgian calcareous grasslands: Active management is vital
A list of ant species collected in eight calcareous grasslands in the Viroin valley (Viroinval, Belgium) is presented. Thirty species were identified, including Temnothorax albipennis, for the first time recorded in Belgium. Ant community composition and chorology of some ant species are discussed. Recommendations on how to use ant community composition and nest densities of several ant species to evaluate management in calcareous grasslands are given. It appears that in locations with encroachment of tall grasses (especially Brachypodium pinnatum) and spontaneous afforestation, due to a complete lack of or to inadequate management, most of the often rare xerophilic ant species are replaced by mesophilic, rather common species.

Article Reference Esperiopsis koltuni sp. nov. (Demospongiae: Poecilosclerida: Esperiopsidae), a carnivorous sponge from deep water of the Sea of Okhotsk (North Pacific)
Esperiopsis koltuni, a new species of the sponge family Esperiopsidae, is described from deep water of the Sea of Okhotsk. The new species has a unique growth form: there is a basal plate with radiating cylindrical branches, whose oval flat distal parts bear filament-like outgrowths. Megascleres are arranged differently in the main part of branches and in their distal flat parts. The dermal membrane contains isochelae with protruding alae and abundant sigmancistras. Microscleres are represented by large anchorate spatuliferous isochelae, small isochelae, sigmas and sigmancistras. Esperiopsis koltuni sp. nov. is hermaphroditic, with parenchymella larva. The larval skeleton consists only of sigmas and sigmancistras. Esperiopsis koltuni sp. nov. can be easily distinguished from other Esperiopsis species by dimensions and combination of spicule types. In particular, it is the only species in the genus with three different size categories of styles. The new species lacks the aquiferous system, has a characteristic body plan with symmetrical lateral expansions, an unusual arrangement of microscleres in the dermal membrane and true sigmancistras. Moreover, prey capture by a filament-like outgrowth of the flat distal part was observed. All of these characteristics indicate that Esperiopsis koltuni sp. nov. is a carnivorous sponge.
