Arable weed vegetation of the northeastern part of the Czech Republic: effect of environmental factors on species composition
Original language description
Factors determining changes in species composition of arable field weed vegetation in the northeastern part of the Czech Republic were studied. Gradsect sampling, i.e. a priori stratified selection of sampling sites, was used for the field research. Using this method, a data set of 174 vegetation plots covering a whole range of basic environmental characteristics in the study area, was compiled in 2001 2003. A set of environmental variables (altitude, annual precipitation, mean annual temperature, soiltype, soil pH and crop type) together with date of sampling was obtained for each plot. Ordination methods were used to determine the effects of variables on arable weed composition. For each variable the gross and net effect on weed species compositionwere calculated. All variables considered in this study had a significant effect on weed species composition and explained 7.25% of the total variation in species data.
