Таксономическая структура и сезонная динамика меропланктона в районе марихозяйства(Мартынова бухта, Севастополь, Чёрное море) IBSS Repository
Лисицкая, Е. В..
На основании обработки 54 проб меропланктона, собранных в районе мидийной фермы (Мартынова бухта, Севастополь, Чёрное море) в 2008 г., определены личинки 56 видов донных беспозвоночных. Дана характеристика таксономической структуры и сезонной динамики меропланктона акватории марихозяйства.

Impact of crop management systems on soil nematode communities in South Brazil Scientia Agricola
Machado,Andressa Cristina Zamboni; Zagatto,Maurício Rumenos Guidetti; Skora Neto,Francisco; Silva,Santino Aleandro da; Zanão Júnior,Luiz Antonio.
ABSTRACT The analysis of nematode communities allows inferring consequences of management practices on the soil food web. We studied the taxonomic structure of nematode communities in preserved areas of the Atlantic forest (native forest = NF) in Ponta Grossa, Paraná State, Brazil, and in three different agroecosystems in neighboring areas to assess the effect of agricultural land use on nematode assemblages. Agroecosystems were located in a red latosol cropped during 30 years under conventional tillage (CT), no-tillage (NT), and minimal tillage (MT). We collected ten composite soil samples in each area in the summer. Nematodes were extracted by Baermann funnel and fixed with formalin. Subsequently, individuals were classified into taxonomic groups and...

SPATIAL AND TEMPORAL CHARACTERIZATION OF SOFT BOTTOM POLYCHAETES IN A SHALLOW TROPICAL BAY (COLOMBIAN CARIBBEAN) Boletín de Investigaciones
Guzmán-Alvis,Angela I.; Lattig,Patricia; Ruiz,José A..
The spatial and temporal variations of the polychaete assemblages were studied within and off a shallow (10-25 m) tropical bay (Bahía de Portete). The polychaete abundances at family level and their trophic mechanisms were used for this purpose. Sediment samples were collected at six stations in this bay during the wet and dry seasons. Multivariate analysis indicated that off- Bay polychaete assemblages were different from the bay ones; this spatial variation was related to sedimentary characteristics, depth and turbid-water conditions. On the other hand, these assemblages did not show significant differences between the dry and wet seasons. The differences between these two assemblages were given specially by the Syllidae, Gonidadidae, Nephtyidae,...
