Invasion of Impatiens glandulifera was reconstructed along rivers in the Czech Republic, central Europe, based on floristic records. The occurrence was assessed along river banks, outside the river banks, and along tributaries downstream from the first records of the species in 1902, 1903, 1978 and 1995, respectively. The following main results were obtained: (a) The species nowadays occupies 77% of the river length in the country. (b) The rivers, investigated in detail, did not differ in the occurrence of the species along the river banks. (c) There were some significant relationships between the penetration of I. glandulifera far from the river banks both in terms of the lateral dimension in the main valley, and upstream along the tributaries, and the time of the first occurrence of the species on the river. (d) It took approximately 20 years from the first occurrence on the main river and the start of spread along the tributaries. The process of invasion is still in progress after about one century and further spread is expected.

This study is devoted to socio-spatial polarisation with regard to the rural environment in Slovakia. In fact, ongoing polarisation processes do not take place only in the rural-urban continuum, but within every single category as well. This is evident especially in the rural environment, which has begun to change significantly in terms of its structure and to diversify to a greater extent. As a result, some parts of the countryside began to stagnate and decline gradually. These parts of the rural environment can thus be referred to as marginal, peripheral. With respect to the proclaimed diversity of the rural environment, this study focuses on selected rural structures, namely mountain areas, the borderland, and the area at the intersection of those two structures. Generally, these parts of the rural environment are often confronted with the phenomenon of marginality and peripherality, and because of the given local predisposition are even more vulnerable to its manifestations. Taking into account the dynamism and multidimensional character of this phenomenon, we can further assume that its manifestation changes in time and space. With the use of ANOVA, we examine a set of selected indicators of socio-spatial polarisation and verify whether and to what extent this dynamism depends on the character of diversified rural structures.

The existence of marginal regions is closely linked to the socio-spatial polarisation of our society. Although marginality and peripherality can be considered a multidimensional phenomenon, the literature as well as social discourses often address only some of its dimensions, in particular on the basis of objective approaches. Such a research is usually based on the quantification of a wide range of statistical indicators, whether of a social, environmental or economic nature. This study aims to capture another equally important dimension of this phenomenon, namely the perception of marginality and peripherality. Drawing on a series of interviews carried out with experts in the field of Irish rurality, this research points to the various perceptions of this phenomenon in rural Ireland. The results once again confirm the complexity of marginality and peripherality, and highlight many differences but also similarities that exist with regard to this phenomenon in the Irish rural context.
