  1. 1. Trädplantering i den hårdgjorda staden : utmaningar och lösningsalternativ

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Ingela Carlgren; [2024]
    Keywords : gatuträd; urbana träd; trädplantering; gatumiljö; urban jord; kompaktering; skelettjord; makadamsubstrat; rotceller; suspended pavement;

    Abstract : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. READ MORE

  2. 2. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

    University essay from SLU/Department of Molecular Sciences

    Author : Ida Ekqvist; [2024]
    Keywords : Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

    Abstract : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

  3. 3. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    University essay from SLU/Dept. of Soil and Environment

    Author : Bella Strid; [2024]
    Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE

  4. 4. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

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

    Author : Ayesha Nagahage; [2024]
    Keywords : Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Abstract : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  5. 5. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.
