21. Diversified agroecosystems for biodiversity and ecosystem services : Ecological intensification of faba bean cropping under land use and climate change
Sammanfattning : Loss of natural habitats and lack of continuous floral resources in intensive agricultural landscapes limit the population growth of ecosystem service providers, such as pollinators. Weakened ecosystem service delivery and climate change stressors contribute to crop yield instability. LÄS MER
22. Local and landscape-level impacts of agricultural intensification on arthropod communities and their interaction networks
Sammanfattning : Arthropods play a central role in agricultural landscapes being responsible for the delivery of many ecosystem services such as pollination, biological pest control, and nutrient cycling. But the current global decline of arthropods is intensified by habitat modification, loss and fragmentation, pesticide use and other intensive management practices. LÄS MER
23. Water, Heat and Solute processes in Seasonally frozen Soils : Experimental and Modeling Study
Sammanfattning : Soil freezing and thawing is of importance in transport of water, heat and solute, which has coupled effects. Solute type and solute content in frozen soil could influence the osmotic potential of frozen soil and decrease freezing point, resulting in differences in soil freezing characteristic curves under various solute conditions.

24. Understanding the causes of spatial variation in pesticide sorption and degradation at the catchment scale
Sammanfattning : Intensive agricultural practices and use of pesticides, essential to achieve high crop yields, present particular risks to soil and water resources which sustain life. Degradation and sorption of pesticides in soils are both spatially variable and also among the most sensitive factors determining losses to surface water and groundwater. LÄS MER
25. Leguminous service crops in cereal production at high latitudes : provision of ecosystem services and disservices from a novel intercropping system
Sammanfattning : Service crops, crops grown to provide services such as soil protection, weed control, or nutrient capture and provision, can reduce the need for mineral fertilisers and intensive weed control. However, high biomass production is necessary in order for these services to be provided. This can be difficult to achieve at high latitudes (e.g. LÄS MER
