Biotopes associated with railway corridor in valley of the river Tichá Orlice (Eastern Bohemia, Czech Republic) ABSTRACT Expansion, invasion or decline of plant species caused by environmental changes belong to the most important phenomenons associated with vegetation cover development. In spite of their often initiation by human activities the above mentioned processes continue then spontaneously and uncontrollably. This study is concentrated to the effect of these mechanisms on the biotope structure along the Tichá Orlice River (Eastern Bohemia, Czech Republic) - in its lowland landscape segment of the canyon character where the second axis of the valley (river flow is the first one) is created by railway line more than 150 years of local history. The case study has the general aim: to treat the present and/or future impact of described trends to plant biota and the degree of its influencing. My diploma thesis investigates functional impact and mutual interaction of the two main migration pathways of exotic species - the T.Orlice river and the railway corridor. It presents qualitative and quantitative changes in plant components of local (semi)natural biotopes by mean of interrelationships among selected ecological groups of species (neophytes, expansive species, and ephemeroids). At the same time, this...
