  1. 1. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Krystyna Muszel; [2023]
    Keywords : Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

    Abstract : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. READ MORE

  3. 2. FLOWERING TIME DEPENDENCE ON MICROCLIMATE ACROSS AN ELEVATIONAL GRADIENT IN ARCTIC PLANT COMMUNITIES

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Maria Pavolotskaia; [2022-07-06]
    Keywords : The Arctic; flowering time; flowering phenology; elevation; elevational gradient; temperature; snowmelt; snow cover; microclimate.;

    Abstract : The Arctic is the fastest-warming region on Earth. Arctic plant communities are highly sensitive to temperature change; temperature-dependent advancement of flowering dates has already been observed in the Arctic. Flowering time is critical for reproductive success. READ MORE

  4. 3. 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

  5. 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 ekosystemvetenskap

    Author : Aleksandra Ivanova; [2019]
    Keywords : physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Abstract : 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

  6. 5. Impact of environmental variables on tundra vegetation onset of flowering explained by survival modelling

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Jonsson; [2019]
    Keywords : Flowering; Phenology; Cox proportional hazard model; Tundra; International tundra experiment; Climate change; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. READ MORE
