2. 1. Plant community assembly in grazed grasslands

   Author : Bryndís Marteinsdóttir; Eriksson Ove; Cousins Sara A. O.; Johan Ehrlén; Meelis Pärtel; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Assembly rules; dispersal limitation; environmental filtering; establishment limitation; ex-arable fields; functional traits; landscape history; semi-natural grasslands; seed bank; seed augmentation; seed rain; trait based filtering; Plant Ecology; växtekologi;

   Abstract : Species assembly into local communities from the surrounding region can be caused either by species failure to reach the site (i.e. seed limitation) or to establish (i.e. READ MORE

4. 2. The role of regeneration in plant niche differentiation and habitat specialization

   Author : Dirk-Jan ten Brink; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; seed mass; seed size; drought; shade; seed germination; seed dormancy; seedling establishment; plant community ecology; assembly rules; habitat specialization; plant recruitment; Regeneration; niche differentiation; phylogenetic independent contrasts; plant traits; soil fertility; comparative ecology;

   Abstract : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. READ MORE

5. 3. Chaperone/usher machinery : a catalyst of virulence organelle assembly

   Author : Xiaodi Yu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Many virulence organelles of Gram-negative bacterial pathogens are assembled via the periplasmic chaperone/usher (CU) pathway. The assembly process is a complex task, involving secretion of organelle subunits via the two membranes and periplasm, subunit folding and assembly. READ MORE

6. 4. Materials exposure: The interface between materials supply and assembly

   Author : Christian Finnsgård; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging; production systems; lean production; materials supply; materials handling; Materials exposure; assembly;

   Abstract : This thesis concerns the supply of components to assembly in production sys- tems, and introduces materials exposure as the interface between materials sup- ply systems and assembly systems. The purpose of the thesis is to explain how materials exposure influences the performance of materials supply systems and assembly systems. READ MORE

7. 5. Plant community assembly during succession from arable fields to semi-natural grassland

   Author : Barbara Christine Schmid; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; diversity; arable-to-grassland succession; space-for-time approach; land-use history; plant community assembly; grazing management; connectivity measures; dispersal vector; vascular plants; grassland specialist conservation;

   Abstract : Large areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. READ MORE
