  1. 1. Biological growth on mineral façades

    University dissertation from Div of Building Materials LTH, Lund university

    Author : Sanne Johansson; Lunds universitet.; Lund University.; [2006]
    Keywords : mortar; moisture transport; mosses; biodeterioration; lichens; moulds; mineral facades; building physics; thin rendering on thermal insulation; heat transfer; biological growth; algae; heat capacity; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : During the last years there has been reported considerable and rapid contamination on newly built rendered façades in Sweden due to biological growth. The problem is believed to occur mostly on façades of render applied on thermal insulation, but apart from this it is difficult to find clear relationships indication which façades might be infected.

  2. 2. Biological growth on rendered façades

    University dissertation from Lund University, Division of Building Materials

    Author : Sanne Johansson; Lunds universitet.; Lund University.; [2011]
    Keywords : render; temperature; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance; TEKNIKVETENSKAP; TECHNOLOGY;

    Abstract : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.

  3. 3. Nutrient Stoichiometry in Benthic Food Webs – Interactions Between Algae, Herbivores and Fish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Antonia Liess; Uppsala universitet.; [2006]
    Keywords : Ecology; ecologial stoichiometry; periphyton; grazer; benthos; trophic interactions; nutrient; algae; Ekologi;

    Abstract : The aim of this thesis was to identify general structuring mechanisms in benthic food webs within the framework of ecological stoichiometry theory. Ecological stoichiometry is defined as the balance of multiple chemical substances in ecological interactions and explicitly considers the combined dynamics of key elements such as carbon (C), nitrogen (N) and phosphorus (P).

  5. 5. The Spider and the Sea : Effects of marine subsidies on the role of spiders in terrestrial food webs

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Kajsa Mellbrand; Stockholms universitet.; [2009]
    Keywords : Natural Sciences Biological Sciences Ecology; Naturvetenskap Biologiska vetenskaper Ekologi; marine subsidies; food webs; stable isotopes; shore ecosystems; predators; spiders; Pardosa; algae; emerging insects; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi; växtekologi; Plant Ecology;

    Abstract : The purpose of this study was to identify if terrestrial arthropod predators on Baltic Sea shores vary in their use of marine versus terrestrial food items, and to construct a bottom-up food web for Baltic Sea shores. The inflow of marine nutrients in the area consists mainly of marine algal detritus and emerging aquatic insects (e.g. READ MORE
