  1. 1. A comparative study of the mosses Ptychostomum pseudotriquetrum and P. bimum : Investigating morphological characters, habitat, and distribution across northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Isabell Sjölander; [2023]
    Keywords : Ptychostomum pseudotriquetrum; Ptychostomum bimum; Crypsis; Leaf decurrency; northern Sweden;

    Abstract : The mosses Ptychostomum pseudotriquetrum and P. bimum (syn: Bryum, Bryophyta) are difficult to distinguish from each other, as they appear morphologically identical besides their difference in sexual condition. Because of their similarities, some researchers treat both as P. pseudotriquetrum, while others treat them as two distinct species. READ MORE

  3. 2. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alexina Brännlund; [2023]
    Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  4. 3. Effects of soil factors on pioneer bryophyte species composition

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Dora Mijić; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

  5. 4. Tree growth and field vegetation in forest edge zones on a property in southeast Sweden

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Pieter van Tongeren; [2023]
    Keywords : tree growth; diversity; field vegetation; edge zones; edge effect;

    Abstract : Summary  In the 1990s a new way of thinking about forestry started. One of the effects of the changing silvicultural practices was that the size of clearcuts became smaller. As the felling areas were reduced in size, the areas where young and older forest meet grew, with this also the occurrence of edge zones increased. READ MORE

  6. 5. SPHAGNUM RE-ESTABLISHMENT ON BARE PEAT - an evaluation of restoration results
