Weed distribution and patches stability on the arable land in framework of the crop rotation

is characterized by high spatial stabilityWeed mapping was carried out 1999 - 2001 in central Bohemia. To determinate the weed occurrence heterogenity the Patchiness-Index was calculated. With the use of Unprog-so...

Spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds

This study reports that spatial and temporal patterns of carabid activity-density in cereals do not explain levels of predation on weed seeds. Possible causes are discussed....
