The alga occurs particularly in humic lakes, and can form dense blooms that can cause problems for water treatment plants and can be a nuisance to swimmers. Small lake area, high water colour, slight acidity and behavioural characteristics of the alga have all been suggested as possible explanations for its increasing distribution and abundance. This thesis evaluates the possible role of various environmental factors in the abundance and distribution of G. semen in Finland. Physicochemical variables from typical lakes where G. semen was present in epilimnetic samples are evaluated, as are the surface water type classes of these lakes. Correlation analysis between the physicochemical factors and the density of G. semen, and logistic regression analysis between the physicochemical and morphological factors of very low abundance G. semen lakes and bloom-forming G. semen lakes were made. The phytoplankton composition during G. semen blooms mainly consisted of flagellates. The alga thrives in high total phosphorus concentration, small, shallow, dark-water humic lakes in Finland. Maybe the most important single environmental change causing abundance of G. semen in Finland is the darkening of lake water colour.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Tuomo Sj\u00f6nberg (tutisjon) on 2015-01-09 08:25:01.134300.
