  1. 21. Eyes in the nest : breeding phenology of Golden Eagles characterized using remote cameras

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Richard Larsson; [2020]
    Keywords : Golden eagle; breeding; Aquila chrysaetos; camera trap; phenology; Sweden;

    Abstract : In situ monitoring of raptor breeding ecology with field personnel is costly, difficult and demanding. Installing camera traps in raptor nests can provide researchers with diverse information and long-term monitoring. Furthermore, it allows for relatively cheap data collection. READ MORE

  5. 24. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Pavlos Aslanis; [2020]
    Keywords : spring barley; crop phenology; crop growth stages; TIMESAT; double logistic; threshold optimization; Sentinel 2; Earth and Environmental Sciences;

    Abstract : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.

  6. 25. Plant phenology and climate change : possible effect on the onset of various wild plant species first flowering day in the UK

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nigel Fox; [2019]
    Keywords : geography; GIS; plants; phenology; climate change; global warming; FFD; IPCC; Bluebell; Garlic mustard; Coltsfoot; Cuckooflower; United Kingdom; Woodland Trust; UK; Earth and Environmental Sciences;

    Abstract : The IPCC states that the planet is significantly warming due to effects of climate change. This warming effect has consequences for phenological events. Many species cannot track rapid climate change, resulting in phenological mismatches. This study looks at an extreme weather event and the longer-term effects of climate change. READ MORE
