11. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. READ MORE

12. The effect of climate on vegetation cover in Swedish mountain regions
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : Climate change, with a higher temperature, is making the snow covered period shorter in the Swedish mountain region. This represents a threat towards plant species at high altitudes which, due to their sensitivity to temperature changes, will likely lead to a change in plant species composition. READ MORE

13. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. READ MORE

14. PLANT MIGRATION AT THE END OF THE WEICHSELIAN GLACIATION : Macrofossil evidence of early coniferous trees at two northern Swedish sites
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Studies of vegetation history bring a new incentive to our understanding of plant survival and migration in arctic environments. For decades, environmental research was based on palynological data and these studies created a notion that tree species such as larch (Larix sibirica) and Scots pine (Pinus sylvestris) did not grow in northern Scandinavia at the end of Weichselian glaciation.

15. Hydrologic modelling of the Zackenberg river basin : an applied study using the Soil and Water Assessment Tool
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Since the 1980s, the Arctic has experienced an amplified warming of more than twice the rate of the global-mean, leading to large-scale changes in the Arctic hydrologic system, ultimately having cascading feedbacks on the global climate. However, few of today’s distributed models manage to capture the complex processes in Arctic hydrology, and therefore, the aim of this thesis was to evaluate the usage of the distributed Soil and Water Assessment Tool (SWAT) model, to see whether it could capture the different surface water paths and processes characterizing the Arctic water cycle.
