1. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants
University essay from SLU/Southern Swedish Forest Research CentreAbstract : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. READ MORE

2. Correlation between Normalized Difference Vegetation Index (NDVI) and in vitro organic matter digestibility (IVOMD) of reindeer pasture plants : Korrelation mellan Normalized Difference Vegetation Index (NDVI) och smältbarhet av renbetesväxter i vomvätska in vitro (VOS)
University essay from SLU/Dept. of Animal Nutrition and ManagementAbstract : Renen livnär sig på många olika betesväxter och den följer växtfenologins utveckling under barmarkssäsongen, vilket resulterar i högkvalitativt foderintag. Levande växtbiomassa kan uppskattas på landskapsnivå genom att använda vegetationsindex som värderar vegetation utifrån spektrala mätningar. READ MORE

3. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.

4. 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

5. Jämförelse av tillväxtrytm mellan somatiska plantor och fröplantor av gran : en studie av tre fältförsök
University essay from SLU/School for Forest ManagementAbstract : Somatic embryogenesis (SE) has the potential to become a useful vegetative propagation method within the Swedish forest tree breeding programme. During the process of propagation, a loss of genotypes results in an uneven production of plants per clone. READ MORE
