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

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

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

   Sammanfattning : 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.

3. 2. Modelling the Water Table in a Bog

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Tobias Bowley; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

4. 3. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Yanhe Zhou; [2023]
   Nyckelord :Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

   Sammanfattning : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. LÄS MER

5. 4. The potential nitrous oxide emissions in a permanent grassland chronosequence

   Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

   Författare :Sandra Lillsjö Kronblad; [2023]
   Nyckelord :nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Sammanfattning : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

7. 5. Effects of soil factors on pioneer bryophyte species composition

   Master-uppsats, Lunds universitet/Examensarbeten i biologi

   Författare :Dora Mijić; [2023]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : 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.
