1. Pathways describe the processes that result in the introduction of alien species from one location to another. A framework is proposed to facilitate the comparative analysis of invasion pathways by a wide range of taxa in both terrestrial and aquatic ecosystems. Comparisons with a range of data helped identify existing gaps in current knowledge of(More)
Over the past century, the potential for aquatic species to expand their ranges in Europe has been enhanced both as a result of the construction of new canals and because of increased international trade. A complex network of inland waterways now connects some previously isolated catchments in southern (Caspian, Azov, Black, Mediterranean seas) and northern(More)
A good understanding of the mechanisms and magnitude of the impact of invasive alien species on ecosystem services and biodiversity is a prerequisite for the efficient prioritisation of actions to prevent new invasions or for developing mitigation measures. In this review, we identified alien marine species that have a high impact on ecosystem services and(More)
Invasive alien species, following an arrival, undergo different colonization stages. The full pattern of an invasion is seldom tracked as many studies on invasive processes only take place over a few years. In this study the invasion of the zebra mussel, Dreissena polymorpha (Pallas, 1771), was followed for more than a ten-year period. It developed an(More)
This review examines the ecological, economical, and public health significance of chironomids and provides examples of chironomid invasions via international shipping and the subsequent local and regional impacts. Dispersal and adaptation mechanisms as facilitators of chironomid invasions are presented, and control methods are discussed. Impacts ranged(More)
The results of the study on spread, pathways, vectors, and ecological impact on the native fauna of alien invertebrate and fish species in the Dnieper River basin are presented. The relationship between invasive processes and basin hydrology is analyzed. It is shown that the main factor in spreading of alien species in the central part of the basin was(More)
Aquatic invasive species are a major threat to native freshwater ecosystems and cause enormous ecological and economic damage worldwide. Didymosphenia geminata (Lyngbye) M. Schmidt is an emerging invasive aquatic species that is spreading aggressively in Southern South America. Using niche analysis and species distribution models (SDMs), we examined niche(More)
