  1. 1. Effects of climate change on boreal wetland and riparian vegetation

    Author : Lotta Ström; Roland Jansson; Christer Nilsson; Sarah Gergel; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biomass; flooding; hydrologic niche; invasibility; riparian zone; riparian plant species; river margin; climate scenario; seed sowing experiment; species composition; species richness; transplant experiment; Terrestrial ecology; Terrestrisk ekologi;

    Abstract : Models of climate change predict that temperature will increase during the 21th century and the largest warming will take place at high northern latitudes. In addition to warming, predictions for northern Europe include increased annual precipitation and a higher proportion of the precipitation during winter falling as rain instead of snow. READ MORE

  3. 3. Ecosystem response to dam removal

    Author : Anna G.C. Lejon; Christer Nilsson; Birgitta Malm Renöfält; Emily Stanley; Umeå universitet; []
    Keywords : dam removal; macroinvertebrates; plant species; plant succession; restoration; riparian zone; sediment deposition; species richness; Sweden; biology; biologi; ekologisk botanik; Ecological Botany; hydrologi; Hydrology;

    Abstract : This thesis aims to improve our understanding of how riverine ecosystems respond to dam removal. Riverine and particularly riparian ecosystems are among the most variable and important features of all landscapes. READ MORE

  4. 4. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks

    Author : Lenka Kuglerová; Roland Jansson; Hjalmar Laudon; Birgitta Malm-Renöfält; John Stella; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; boreal forest; channelization; groundwater; Krycklan catchment; liverworts; mosses; riparian buffers; riparian vegetation; river restoration; species richness; stream network; stream size; vascular plants;

    Abstract : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.

  5. 5. Conservation of transcription factors in infected cells of nitrogen-fixing root nodules

    Author : Behnoosh Rashidi; Katharina Pawlowski; Karsten Niehaus; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; root nodules; actinorhiza; legumes; infection thread; Frankia; subtilase; leghemoglobin; chitinase; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Infected cells of nitrogen-fixing root nodules are the only plant cells that can stably internally accommodate a eubacterial symbiont. In the context of studying the differentiation of infected cells, we set about to analyse the conservation of infected cell-specific transcription factors using altogether four different promoters from genes showing infected cell-specific expression, or nodule-specific expression.
