16. Can the introduction of the topographic indices in LPJ-GUESS improve the spatial representation of environmental variables?
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Ecosystem modelling is an always evolving science trying to catch the complexity of the nature and its principles to model environmental responses in a realistic way. Over and over, models try to introduce more variables and interactions to achieve better representations of phenomena of interest like the responses of the ecosystem to a fast changing world (climate change, land use change).

17. Weed suppressive ability of crop mixtures
University essay from SLU/Dept. of Crop Production EcologyAbstract : In order to assess the weed suppressive ability of a pea/barley crop mixture and the component crops in sole cropping, a controlled outdoor experiment was performed at The Swedish University of Agricultural Sciences, Ultuna, Sweden, in the summer of 2015. A substitutive completely randomized experimental design was used with seven treatments and six replicates. READ MORE

18. Kan skillnader i bladarea, biomassa och kväveförklara produktionsskillnader mellan tall (Pinus sylvestris) och gran (Picea abies)?
University essay from SLU/Southern Swedish Forest Research CentreAbstract : I Sveriges boreala vegetationszon domineras skogen av tall och gran och produktionen begränsas av tillgången på kväve. Tillgängligt kväve tas upp genom rötterna och koncentreras till trädets aktiva delar som t.ex. barr, grenar och bark. READ MORE

19. Environmental Controls on Snow Cover Thickness and Water Equivalent in Two Sub-Arctic Mountain Catchments
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The spatial variability of snow cover characteristics (depth, density, and snow water equivalent [SWE]) has paramount importance for the management of water resources in mountain environments. Passive microwave (PM) inference of SWE from space-borne instrumentation is increasingly used but the reliability of this technique remains limited in mountainous areas. READ MORE

20. Feasibility of a low-cost weather sensor network for agricultural purposes : a preliminary assessment
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : This study has focused on challenges encountered when setting up a weather-network for agricultural purposes (e.g. linking temperature to the suitability of crops and pest incidence) with only low-cost sensors and materials.
