  1. 11. 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

  3. 12. Compact & Lightweight Antenna Designs for Harmonic Radar Application

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

  5. 14. Effect of diet and density on larval immune response and larval and adult host-preference in Spodoptera littoralis

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Sophie Chattington; [2015]
    Keywords : artificial encapsulation; Egyptian cotton leafworm; immune response; innate preference hierarchy; larval density; larval development; larval memory; oviposition choice; phenoloxidase; Spodoptera littoralis; Y-tube;

    Abstract : Polyphagy presents difficulties to an insect, especially in terms of host choice. The adult insect must choose from a large number of possible host plant species, something which is considered to require extensive neural capacity to process. READ MORE
