2. 1. Reproductive strategies and liming responses in forest field-layer flora

   Author : Annika Kruuse af Verchou; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; species turnover; species richness; sexual reproduction; podzol; pH; Lamiastrum galeobdolon; forest liming; demography; Cambisol; clonal plants; SRE; vegetative reproduction; VRE; Plant ecology; Växtekologi;

   Abstract : Liming increased species richness, in accordance with the species pool hypothesis, and number of plants of individual species in beech forest field-layer vegetation, by increasing establishment by seedlings and vegetative offspring. Turnover rates also increased, suggesting the explanatory value of the carousel model. READ MORE

5. 3. Nitrification and Nitrifying Bacterial Communities in Coniferous Forest Soils : Effects of Liming and Clear-Cutting

   Author : Jenny Bäckman; Wietse de Boer; Linköpings universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : This thesis deals with the effects of liming and clear-cutting on nitrification in hemi-boreal and northern temperate coniferous forest soils. The approach has been to study both the potential nitrification and the community structure of the ammonia-oxidising bacteria, which carry out the first step of autotrophic nitrification. READ MORE

6. 4. A paleolimnological perspective on liming – implications for defining reference conditions in Swedish lakes

   Author : Matilda Norberg; Ingemar Renberg; Helen Bennion; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acidification; Liming; European Water Framework Directive; Reference condition; Diatoms; Paleolimnology; Monitoring; Lake sediments; Earth sciences; Geovetenskap; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

   Abstract : Using paleolimnological techniques, I have studied surface-water acidification and the effects of liming in Swedish lakes on a decadal to millennial time-scale. The overall objective was to contribute to the discussion on the fulfilment of goals within the Swedish liming program. READ MORE

7. 5. Seed production and natural regeneration of beech (Fagus sylvatica L.) in southern Sweden

   Author : Rolf Övergaard; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : When mature beech forests are harvested, the new regeneration is established by natural regeneration, which is by using the seeds from the old stand to create the new generation. Most often the seed from a single mast year is used preceded by site preparation. READ MORE
