Ecology of expansion species is still a hot topic. The antropogenic landscape gradually occurred since the Neolithic . The result has been a change in the structure of plant communities and the successful expansion of species such as Calamagrostis epigejos.
C. epigejos is expansive, perennial, long-stemmed, rhizomatous grass. Its important characteristic are very large ecological amplitude, high biomass production and a ability adjust habitat conditions.
Experiments and studies that are included in dissertation, have the following basic objectives: (1) Investigate the expansion of C. epigejos in plant community. (2) Investigate the theoretical degree of stability of this phytocenosis. (3) Determine the response of C. epigejos to nutrients availability. (4) Test of possibility eliminating of C. epigejos. (5) Suggest a practical use of C. epigeos.
Primarily, we monitored the reaction of interest species to management (aplication of N, P, K nutrients, mowing in various combinations). We were interested in its behavior in the plant community. It founded field and pot experiment. Results of field experiment were also used to calculate the theoretical measure of the stability of individual variants. Further research has been directed at eliminating C. epigejos using wireworms (Elateridae larvae species). The study which uses C epigejos for monitoring of deposition of heavy metals, has shown that aspects of the global expansion of the grass are not always negative.
