  1. 1. Biodiversity in fragmented boreal forests assessing the past, the present and the future

    Author : Håkan Berglund; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; bryophytes;  CWD;  edge effects;  fragmentation;  fungi;  habitat destruction;  historical records;  indicator;  lichens;  regression;  species-area relationship;  value pyramids;  woody debris ; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The aims of this thesis are to (1) analyze the predictability (indicators) of plant and fungal species diversity in old-growth forests, and (2) assess the history and biodiversity of woodland key habitats (WKHs) and their potential to maintain species diversity in fragmented boreal forest landscapes. Predictability was explored in Granlandet nature reserve, an unexploited landscape composed of discrete old-growth Picea forest patches of varying size isolated by wetland, reflecting conditions of insular biota at stochastic equilibrium.

  2. 2. Function and dynamics of woody debris in boreal forest streams

    University dissertation from Umeå : Ekologi och geovetenskap

    Author : Niklas Dahlström; Mittuniversitetet.; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi; Boreal forest;  CPOM;  CWD;  forest management;  geomorphology;  LWD;  riparian forest;  retention;  residence time;  streams;  Sweden;  woody debris;

    Abstract : The work in this thesis deals with (1) the effects of woody debris on stream channel morphology and retention of organic material, and (2) the dynamics of woody debris and its relation to riparian forest history and composition. The studied stream reaches are situated in mature, productive forests in the boreal zone of Sweden. READ MORE

  3. 3. Cost-effectiveness of measures to improve biodiversity in Swedish forests

    University dissertation from Umeå : Ekologi och geovetenskap

    Author : Hans Ekvall; Sveriges lantbruksuniversitet.; [2014]

    Abstract : The main objective of this thesis is to analyse the cost-effectiveness of measures, which improve biodiversity among life forms dependent on coarse woody debris (CWD). The amount of CWD in forest land has decreased due to modern forest management. READ MORE

  4. 4. Middle Ear Cholesteatoma Surgical Treatment, Follow-up and Hearing Restoration

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lennart Edfeldt; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

    Abstract : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. READ MORE

  5. 5. Luminescent molecular recognition of pathognomonic and aging associated protein aggregates

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Daniel Sjölander; Linköpings universitet.; Linköpings universitet.; [2014]

    Abstract : Various protein inclusions have been recognized to be associated with aging and pathogenic conditions, such as in Alzheimer’s disease, Parkinson’s disease, Type 2 diabetes, and the prionoses Creutzfeldt-Jakob disease, Chronic wasting disease (CWD), and Mad cow disease. The causative transition of protein aggregation is the alteration in the conformation of the protein that renders the protein susceptible towards self-assembly. READ MORE
