О концепции экологической группировки гидробионтов.
Provedor de dados: 13
Autores: Протасов, А. А.
Рассмотрены основные положения концепции экологической группировки гидробионтов. Предложена их уточнённая классификация. Обсуждается вопрос о взаимосвязи группировок, облигатных и случайных или временных представителях группировок, на основе адаптационного градиента. Рассмотрены вопросы эволюции экологических группировок.

The neuston of the Karadag nature reserve (Crimea, the Black Sea) was investigated in the season 2005– 2008 for the first time. The benthic invertebrates consist of 59 species were identified. The maximum number of kinds was noted at midnight.

Enhanced heterotrophic activity in the surface microlayer of the Mediterranean Sea
Provedor de dados: 5
Autores: Obernosterer, Ingrid; Catala, Philippe; Reinthaler, Thomas; Herndl, Gerhard J.; Lebaron, Philippe.
The abundance and activity of heterotrophic and autotrophic organisms were determined in the surface microlayer (SML) at marine and estuarine sites in the NW Mediterranean Sea from May to July 2003. At all study sites, community respiration in the SML exceeded that in the subsurface water (SSW) by factors between 1.7 and 28. The abundance of heterotrophic bacteria and the major groups of the autotrophic community displayed consistent, but low enrichment factors (EF) for the SML (mean 1.3). In contrast, EF for the abundance of heterotrophic nanoflagellates and the concentration of particulate organic carbon were, on average, 4 and 7, respectively. Community respiration rates in the SML were related to the concentration of total organic carbon; however, no...

Annual variation in neustonic micro- and meso-plastic particles and zooplankton in the Bay of Calvi (Mediterranean–Corsica)
Provedor de dados: 5
Autores: Collignon, Amandine; Hecq, Jean-henri; Galgani, Francois; Collard, France; Goffart, Anne.
The annual variation in neustonic plastic particles and zooplankton was studied in the Bay of Calvi (Corsica) between 30 August 2011 and 7 August 2012. Plastic particles were classified into three size classes, small microplastics (0.2–2 mm), large microplastics (2–5 mm) and mesoplastics (5–10 mm).  74% of the 38 samples contained plastic particles of varying composition: e.g. filaments, polystyrene, thin plastic films. An average concentration of 6.2 particles/100 m2 was observed. The highest abundance values (69 particles/100 m2) observed occurred during periods of low offshore wind conditions. These values rose in the same order of magnitude as in previous studies in the North Western Mediterranean.  The relationships between the abundance values of the...
