  1. 1. How does grazing and burning affect the occurrence and development of vascular plants?

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Felicia Ivarsson; [2023-02-17]
    Keywords : Keywords: burning; grazing; plot; restoration; plant; flower;

    Abstract : Grazing and burning are disturbances that can be used for management of landscapes that are in need of restoration. When applying these disturbances, you can create a more diverse flora and fauna and control the grazing pressure from domestic cattle. READ MORE

  3. 2. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Danilo Esteban Ortiz Sarasty; [2023]
    Keywords : Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Abstract : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  4. 3. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    University essay from

    Author : Delshad Mansour Ayoubi; [2022-12-06]
    Keywords : Medical physics; Activity concentration; Transfer coefficient; Dose;

    Abstract : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. READ MORE

  5. 4. Preventing the spread of the invasive plant Lupinus polyphyllus.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : David Brobäck; [2015]
    Keywords : Lupinus poluphyllus; large-leaved lupin; invasive species; spread; invasive species management; road verges; Lupinus poluphyllus; blomsterlupin; invasiva arter; spridning; bekämpning; vägkanter;

    Abstract : Invasive species are an increasing problem worldwide, threatening indigenous communities and species. Many human-made environments promote introductions of alien species and one such habitat is road verges. The invasive plant Lupinus polyphyllus is benefiting from these habitats and is today widespread along road verges in many parts of Sweden. READ MORE

  6. 5. Analysis of Selection and Genetic Drift in a Dioecious Plant : Spatial Genetic Structure and Selection in Phenotypic Traits in a Young Island Population of Silene dioica

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

    Author : Bea Angelica Andersson; [2014]
    Keywords : selection; genetic drift; quantitative trait; FST; PST; drift; evolution; founder event; gene flow; Silene dioica; dioecious; substructure; subpopulation; phenotypic trait; pollinator preference; Skeppsvik; Sweden; succession;

    Abstract : Selection and genetic drift are often competing forces in shaping genetic structure in populations. Genetic drift will often effectively cancel out the effect of selection when population sizes are small, such as in colonizing island populations. READ MORE
