Untersuchung der bewegungsgleichungen,ped”,or what syndrome of traits must it possess to survive and flourish at a given locality. In the current human-mediated biodiversity crisis, where alien species play an important role, we need to know whether some species are inherently better equipped to become invasive when moved to new areas b

Untersuchung der bewegungsgleichungen, establish themselves in environments to which they have had no opportunity to adapt (Sax and Brown 2000). This paradox is usually resolved by invoking pre-adaptations of non-indigenous species to novel environments. The idea is that some species are successful invaders because they have attributes

The amount of ecosystem alteration is related to predominant land uses,which can be summarized into four categories of increasing impact: (1) conservation - nature reserves, wildernes

Other drivers of global change - such as alteration of the atmospheric composition and associated climate change, changing patterns of land use that fragment habitats and alter disturbance regimes, and increasing levels of airborne nitrogen deposition - also influence resource dynamics and specie

Perhaps rates of invasions in marine systems are simply lower than in other systems, but more likely lack of scrutiny, difficulty with taxonomic resolution, and unusual life-history characters of marine organisms cause the vast majority of invasions to go unrepor

Quantitative studies on changes in abundance of non-native species and on species composition of native communities complement these reports (e.g. Van den Brink et al. 1990, 1996; Haas et
