1. Effekter av torka och vall på marklevande nematoder
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Nematoder finns i stora mängder i marken och påverkar jordbruket på flera sätt. Det finns nematoder som har en positiv inverkan då de bidrar till markens näringsomsättning och mobiliserar kväve men det finns även växtätande nematoder som kan orsaka skördeförluster. LÄS MER
2. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. LÄS MER
3. Vegetation responses to summer- and winter warming : flower power in the Alaskan tussock tundra?
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Plants have an important role in the tundra carbon (C) cycle by storing C in primary production and thus potentially counteract the C released from thawing permafrost. Tundra vegetation is limited by nitrogen (N), which is predicted to increase with rising temperatures and increased snow depth. LÄS MER
4. The Vertical Route Forecast : an Evaluation of a New Flight Path Based Weather Forecast Product with HARMONIE-AROME High Resolution Forecasts over Scandinavia
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : As a complement to existing weather forecast products for aviation, a prototype of a new product is presented and evaluated. It shows the atmosphere in a vertical cross section along the intended route. LÄS MER
5. Commercial eucalyptus plantations with Taungya system in Lao PDR: analysis of tree root biomass
Kandidat-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : The increasing demand for wood, fibre and pulp coupled with efforts to mitigate greenhouse gas emission has put immense importance on the development of forest plantations. The rapidly growing human population will also face shortage of food, particularly in developing world where agricultural productivity is generally low. LÄS MER
