Subject and purpose of work: The contemporary labour market in Poland is characterised by a large scale of migration of people, caused by the desire to find a good job. This situation is facilitated by the possibility of free movement within the European Union. The purpose of this study is to present the concept of migration, its types, causes and effects. Statistics related to the labour migration of Poles are also presented. The subject of the study is the migration activity of Poles abroad. The obtained data are presented using the descriptive method and graphical methods. Materials and methods: National literature and statistical data were used during the work on the research problem. Results: Statistics showing the scale of the migration phenomenon in Poland are presented. The research period covered the years 2013-2018. Conclusions: Over the period under consideration, the number of Poles travelling abroad for work purposes decreased. This may be due to the decreasing number of unemployed people and the lower unemployment rate in Poland. At the same time, an increasing number of job offers in the national labour market can be observed.

Subject and purpose of work: This article analyzes the factors depicted in the literature as essential for the emergence of far-right parties and assesses the importance of unemployment, immigration and political establishments in the failures of the far-right wing parties in Sweden and Finland in early 2000s. Materials and methods: Multi-methods approach is used in this study including case studies and a novel technique based on Boolean algebra. Results: The findings of this paper lead to the conclusion that the correlation between unemployment rates and the electoral strength of far-right parties is weak and does not support simplistic thesis such as high unemployment leads to extremism. Moreover, despite objectively favorable conditions in terms of high immigration rates, the presence of non-European immigrants in a country does not in itself explain the emergence of far-right parties. Conclusions: The study points to the importance of political factors such as the differences between the mainstream parties and tackling the immigration issue by the Liberal Party in Sweden and the wide ideological span of the coalition government and the role of Finland’s special relationship with the USSR that militated against the emergence of far-right parties in these countries.

Many fish species migrate through the supply streams of fish cultivation facilities (ponds, farms and hatcheries). These streams are the sources of so-called exotic species which are undesirable in open waters. They appear in the Dobra River when ponds are drained and during other hatchery works conducted in spring (April-May) and autumn (October-November). As a result, the number of species varies seasonally from six to 15. The ichthyofauna density increases from 1.70 to 124.94 specimens 100 m⁻² , while the biomass grows from 27.86 to 962.95 g 100 m⁻² . The majority of escapee fish belong to limno- and stagnophilous species. Most of these fish remain in this foreign environment only for a short time of 2 to 4 months.

We studied the influence of immigration on the dynamics ofMicrotus ochrogaster Wagner, 1842 andM. pennsylvanicus Ord, 1815 populations in alfalfa, bluegrass, and tallgrass prairie in east-central Illinois for 25 years. The numbers of immigrants in a site were positively correlated with overall population densities of the species in the vicinity of the study sites and within the study site. Population density of the other species was not correlated with immigration of either species. Immigrants did not differ significantly from residents with respect to sex-ratio and reproductive condition. Persistence of immigrantM. pennsylvanicus was lower than that of resident adults in all three habitats, while that of immigrantM. ochrogaster was lower than that of resident adults in alfalfa, where the species was most abundant. Neither the absolute number of immigrants nor the proportion of the population composed of immigrants indicated an effect of immigrants on among- and within-habitat differences in demography and population fluctuations of either species. Immigrants may have been an important factor in maintenance ofM. pennsylvanicus in alfalfa, a low-quality habitat, but the influence of immigration on the dynamics of populations inhabiting other habitats was insubstantial.

A population of urban free-ranging dogs Canis familiaris Linnaeus, 1758 was studied in Katwa, West Bengal, India. The analysis of changes in the density of the dog population over a period of 4 years revealed a considerable stability of this population. Mean (±SD) seasonal population density was 185 ± 19 dogs/km , ranging from 156 to 214 dogs/km . A sex ratio of 1.37:1 in favour of male was recorded in this study. High mortality (67%) occurred under the age of 4 months, and 82% mortality occurred within the age of 1 year. Among the adults, 24% mortality under the age of 2.6 year was recorded. Only a single breeding cycle and synchronization of breeding was observed. Immigration was observed as a crucial factor affecting the stability of this population.
