1. The Valeriana officinalis aggregate in Sweden. A preliminary study.
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Common valerian (Valeriana officinalis L.) is a species of flowering plants native to Europe, the roots of which have been used in folk medicine for centuries. But due to high diversity in morphology and chromosome numbers, different populations in V. LÄS MER
2. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

3. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. LÄS MER
4. Värdväxter hos Coleophora - säckmalar : koppling till utbredning och hotstatus
Kandidat-uppsats, SLU/Dept. of EcologySammanfattning : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. LÄS MER
5. Spatial and Temporal Dynamics of Carbon Sequestration in Stockholm County's Green areas : A GIS-based Analysis
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The human influence of global climate is an issue currently assessed in various mitigation strategies. Stockholm County has committed to becoming carbon neutral by 2040 and negative by 2045 according to the Paris agreement. LÄS MER
