1. The natural pest control potential of different landscapes : mapping the ecosystem service in three regions of Sweden
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Natural pest control describes the process of natural enemies suppressing pests and thus reducing crop damage and stabilizing yields. How well these beneficial arthropod predators and parasitoids can thrive in a landscape is influenced by the land-use types in the vicinity, such as forest patches, pastures, or agricultural fields, and their ability to provide resources.

2. Expressing ecosystem model output and Swedish forestry goals with composite indictors
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Forest ecosystems provide a wide range of services necessary for maintaining environmental health and human well-being. Ecosystem models help inform how various management strategies respond in different regions to changing climate conditions. LÄS MER
3. Analysis of urban ecosystem condition indicators for the large urban zones and city cores in EU : threshold assessment and exploration of the relation to ecosystem services through the application of G.I.S
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : As almost three out of four EU citizens live in urban areas and this number is expected to further grow, studies on urban ecosystems and their services are crucial to understand a city’s environmental structure and capabilities. The European Commission has published a relative report which suggests an urban ecosystem condition indicator framework, yet without suggesting respective thresholds that might indicate a “desired” environmental condition of the city.

4. Indicators for ecosystem services in urban green space management
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Urban green spaces are put under high pressure due to increasing population density in cities. This problem will potentially accelerate where the densification in the cities continues. LÄS MER
5. Overstory dynamics as an indicator of ecosystem services from the understory vegetation in coniferous forests in Sweden
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Understory vegetation is a wide and diverse part of the forest environment, which provides a lot of information about the forest, its condition and ecosystem services. Understory vegetation is affected and moulded by the species composition and density of the overstory, which changes growth conditions and productivity in the lower layers during the whole rotation period.
