  4. 3. Evaluating habitat suitability and spectral heterogeneity models to predict weed species presence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christina Fotiou; [2014]
    Keywords : GARP; herbicide resistant weeds; climate change; spatial heterogeneity; habitat; regression; NDVI; Physical Geography and Ecosystem Analysis; GIS; Earth and Environmental Sciences;

    Abstract : The aim of this study is to analyze whether the presence of weed species resistant to herbicides is related to landscape heterogeneity and environmental variables. C3 and C4 weed species, such as Chenopodium album, Conyza canadensis, Amaranthus retroflexus, Papaver rhoeas, Sorghum halepense, Echinochloa crus-galli and Lolium rigidum, are studied in two differing bioclimatic countries, Greece and Germany.
