CIGESMED for divers: Establishing a citizen science initiative for the mapping and monitoring of coralligenous assemblages in the Mediterranean Sea ArchiMer
Gerovasileiou, Vasilis; Dailianis, Thanos; Panteri, Emmanouela; Michalakis, Nikitas; Gatti, Giulia; Sini, Maria; Dimitriadis, Charalampos; Issaris, Yiannis; Salomidi, Maria; Filiopoulou, Irene; Dogan, Alper; D'Avray, Laure Thierry De Ville; David, Romain; Cinar, Melih Ertan; Koutsoubas, Drosos; Feral, Jean-pierre; Arvanitidis, Christos.
Background Over the last decade, inventorying and monitoring of marine biodiversity has significantly benefited from the active engagement of volunteers. Although several Citizen Science projects concern tropical reef ecosystems worldwide, none of the existing initiatives has yet specifically focused on their Mediterranean equivalents. Mediterranean coralline reefs, known as “coralligenous”, are bioherms primarily built by calcifying rhodophytes on hard substrates under dim-light conditions; they are considered hotspots of biodiversity and are extremely popular among divers due to their complex structure, conspicuous biological wealth and high aesthetic value. Nevertheless, data on their distribution, structure and conservation status is lacking for...

Diversity and composition of macrobenthic community associated with sandy shoals of the Louisiana continental shelf ArchiMer
Dubois, Stanislas; Gelpi, Carey; Condrey, Richard E.; Grippo, Mark A.; Fleeger, John W..
Along the Louisiana, USA continental shelf, sandy shoals are shallow, possibly oxygen-rich "islands" surrounded by deeper muddy deposits prone to hypoxia. Shoals also contain significant quantities of fine sand that may be mined in the future for coastal restoration. The ecological role of shoals remains poorly understood and we hypothesized that shoals provide critical habitat for benthic invertebrates. Using Ship Shoal as a model system, we assessed the diversity and structure of macrobenthic assemblages and how community structure varies with season and environmental parameters. High biomass (averaging 26.7 g m(-2)) and high diversity (161 species) of macrobenthos was found in 2006. Polychaetes (45%-72 species) and crustaceans comprised most of the...

New species from Phytophthora Clade 6a: evidence for recent radiation Naturalis
Burgess, T.I.; Simamora, A.V.; White, D.; Wiliams, B.; Schwager, M.; Stukely, M.J.C.; Hardy, G.E.St.J..
During routine vegetation health surveys in the southwest of Western Australia (SWWA), several Phytophthora isolates with affinity to Clade 6a have been recovered. In this study, all known taxa from Clade 6a, P. inundata, P. humicola, P. gemini, P. ‘walnut’ and P. ‘personii’, and the new isolates were compared based on morphology and DNAsequence data from three nuclear genes and two mitochondrial genes resulting in the description of five new species, P. balyanboodja, P. condilina, P. cooljarloo, P. kwongonina and P. pseudorosacearum. With the exception of P. gemini and P. humicola, all species from Clade 6a have been recovered from natural ecosystems in SWWA. These species are morphologically similar, with predominantly ovoid sporangia and nested and...

Diversity of wasps (Hymenoptera: Aculeata: Vespidae) along an altitudinal gradient of Atlantic Forest in Itatiaia National Park, Brazil Rev. Bras. entomol.
Ribeiro,Daniele Guedes; Silvestre,Rogerio; Garcete-Barrett,Bolívar R..
ABSTRACT Surveying the diversity of stinging wasps (Hymenoptera: Aculeata) provides an important information base to assist in biodiversity conservation and the management of forest reserves, as wasps depend on and maintain the population balance of several other groups of insects. In accordance, this paper presents an altitudinal survey of wasps (Hymenoptera, Aculeata, Vespidae) in Itatiaia National Park, Brazil, which is a protected area covered by Atlantic Forest in a mountainous landscape, with altitudes ranging between 540 and 2791 metres above sea level. Six altitudinal zones were sampled with entomological net, and the abundance and diversity of the species were indicated by zones. Field sampling took 288 h of discontinuous activity, which was...
