Establishing management programs to preserve the benthic communities along NW Pacific and Arctic Ocean (AO) requires a deep understanding of composition their responses environmental stressors. In this study, we thus examine patterns community species richness Seas investigate most important drivers those patterns. Overall found trend decreasing toward higher latitudes deeper waters, peaking in...
In present study, besides investigating benthic communities and their demographics in Choghakhor wetland, the water quality has been evaluated and classified. Then, 10 stations were selected and sampling of benthos was done every 45 days since April 2010 to March 2011, with 3 replications at each station. Samples were obtained by Ekman grab Sampler (surface 400 cm2). The collected samples were ...
Patchy occurrences of benthic drift algae (i.e. loose lying macroalgal mats) may increase habitat complexity on normally bare soft bottoms, but at the same time, extensive amounts of drifting algal mats are known to stress the benthic fauna. This paper presents results of the first detailed study of the fauna associated with drift algal mats in the northern Baltic Sea. In order to assess the im...
Abstract Ecological theory predicts that the relative distribution of primary production across habitats influence fish size structure and biomass production. In this study, we assessed individual, population, community-level consequences for brown trout ( Salmo trutta ) Arctic char Salvelinus alpinus variation in estimated habitat specific (benthic pelagic) total whole lake (GPP gross 27 north...
