Geoenvironmental Implications and Biocenosis of Freshwater Lakes in the Arid Zone of East Kazakhstan
Steppe and semi-desert lakes of Central Asia represent unique still poorly known aquatic ecosystems. The paper provides summaries multi-proxy environmental biological investigations the previously unexplored ground Sibe in naturally pristine zone East Kazakhstan, their contributions to people. Data on taxonomic composition zooplankton zoobenthos these freshwater lacustrine basins are presented ...
Offshore fish farming is predicted to increase in the near future driven by the lack of coastal space. In this review I discuss the environmental issues of offshore farming from experience in coastal farms. Even more so than in coastal farms, a rapid and wide dispersal of dissolved waste products is predicted for offshore farms. Despite wider dispersal of particulate waste products, fast sinkin...
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
We examined the habitat of juvenile haddock on the eastern Scotian Shelf (off Nova Scotia, Canada) in relation to grab-sampled benthic macrofaunal invertebrate species assemblages in order to determine whether there were significant differences in benthic macrofauna between areas of historically persistent high and low juvenile haddock abundance. Our analyses were conducted over two spatial sca...
The Chironomidae occupy different habitats along the lotic system with their distribution determined by different factors such as the substrate characteristics and water speed. The input of vegetable material from the riparian forest allows a higher habitat diversity and food to the benthic fauna. The main aim of this paper is to verify the structure and spatial distribution of the Chironomidae...
Sea-level rise induced by climate change may have significant impacts on the ecosystem functions and ecosystem services provided by intertidal sediment ecosystems. Accelerated sea-level rise is expected to lead to steeper beach slopes, coarser particle sizes and increased wave exposure, with consequent impacts on intertidal ecosystems. We examined the relationships between abundance, biomass, a...
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...
On March 11(th), 2011 the Mw 9.0 2011 Tōhoku-Oki earthquake resulted in a tsunami which caused major devastation in coastal areas. Along the Japanese NE coast, tsunami waves reached maximum run-ups of 40 m, and travelled kilometers inland. Whereas devastation was clearly visible on land, underwater impact is much more difficult to assess. Here, we report unexpected results obtained during a res...
Microplastics are ubiquitous in the marine environment, however, mechanisms governing their uptake by, and burial within, seabed habitats poorly understood. In this study, microplastic its impact on fauna-mediated sedimentary processes was quantified at three coastal sites, potential contribution of burrowing faunal communities to process assessed via functional trait diversity analysis field d...
