Abstract
|
|
|
|
The invasion of Ambrosia artemisiifolia in the Ukrainian Carpathians Mts. and the Transcarpathian Plain in Central Europe was reconstructed on the basis of floristic records. The first spontaneous occurrence was dated from the beginning of the 1940s. Within the next 55 year period, the distributional spread speed of the species was of 67.6 km /y (by the average data). The occupied area by A. artemisiifolia in the range of the studied areas is about 3716.5 km2 now. The features of behavior of the invader and the habitat preference were determined. The frequency of occurrence by socio?logic?ecological classification was carried out. The generalized model of correlations among the gravitation, the active temperature sum and the disturbance gradients and the frequency of occurrence of the species was presented. The scheme of the invasion stages of A. artemisiifolia is reflected in the population status changes of the species during the areal dynamics
