1. 1. 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 ekosystemvetenskap

   Författare :Christina Kourdounouli; [2018]
   Nyckelord :geography; GIS; EU; urban atlas; larger urban zone; city core; urban ecosystem; ecosystem condition indicator; urban green space; impervious surface; natural area; agricultural area; protected area; abandoned area; number of inhabitants per area; artificial area per inhabitant; urban ecosystem condition indicator thresholds; ecosystem services; recreation opportunity spectrum; NO2 removal by urban vegetation; urban heat island effect; cluster analysis; precipitation; temperature; climate adaptation; Earth and Environmental Sciences;

   Sammanfattning : 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.

3. 2. Overstory dynamics as an indicator of ecosystem services from the understory vegetation in coniferous forests in Sweden

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Daniel Boczniewicz; [2017]
   Nyckelord :berry production; biodiversity; ecosystem services; game potential; overstory vegetation dynamics; Picea abies; Pinus sylvestris; understory vegetation; Vaccinium myrtillus; Vaccinium vitis-idaea;

   Sammanfattning : 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.

4. 3. Land Surface Phenology as an indicator of performance of conservation policies like Natura2000

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Gunjan Sharma; [2016]
   Nyckelord :MODIS NDVI; Natura2000; Land Surface Phenology LSP ; ecological indicators; TIMESAT; trend analysis; GEM; Earth and Environmental Sciences;

   Sammanfattning : Considering the growing pressure on various ecosystems all around the world, the development of ecological indicators for assessing the health and condition of the ecosystems has become an integral part of environmental management and policy making efforts. Such indicators do not only simplify the complex ecosystem processes but can also act as a measure of performance of a conservation policy. LÄS MER
