  2013 MAY 3 (VerticalNews) -- By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Data detailed on Freshwater Research have been presented. According to news originating from London, United Kingdom, by VerticalNews correspondents, research stated, "1.The biological structure of arctic lakes is changing rapidly, apparently in response to global change processes such as increasing air temperatures, although altered nutrient stoichiometry may also be an important driver. Equally important, however, are local factors (e.g. landscape setting, hydrological linkages and trophic interactions) that may mediate responses of individual lakes at the regional scale. ...read more

  2013 MAY 3 (VerticalNews) -- By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Freshwater Research have been published. According to news reporting originating in Copenhagen, Denmark, by VerticalNews journalists, research stated, "1.Arbuscular mycorrhizal fungi (AMF) commonly colonise isoetid species inhabiting oxygenated sediments in oligotrophic lakes but are usually absent in other submerged plants. We hypothesised that organic enrichment of oligotrophic lake sediments reduces AMF colonisation and hyphal growth because of sediment O2 depletion and low carbon supply from stressed host plants. 2.We added organic matter to sediments inhabited by isoetids and measured pore-water chemistry (dissolved O2, inorganic carbon, Fe2+ and ), colonisation intensity of roots and hyphal density after 135days of exposure. 3.Addition of organic matter reduced AMF colonisation of roots of both Lobelia dortmanna and Littorella uniflora, and high additions stressed the plants. ...read more

  2013 MAY 3 (VerticalNews) -- By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- A new study on Freshwater Research is now available. According to news reporting originating from Miami, Florida, by VerticalNews correspondents, research stated, "1. The niche variation hypothesis predicts that among-individual variation in niche use will increase in the presence of intraspecific competition and decrease in the presence of interspecific competition. ...read more
