Global meta‐analysis of native and nonindigenous trophic traits in aquatic ecosystems

摘要: Ecologists have recently devoted their attention to the study of species traits and role in establishment spread nonindigenous (NIS). However, research efforts mostly focused on studies terrestrial taxa, with lesser being dedicated aquatic species. Aquatic habitats comprise interconnected waterways, as well exclusive introduction vectors that allow unparalleled artificial transport propagules. Consequently, commonly facilitate biological invasions systems may not be represented environments. We provide a global meta-analysis conducted both marine freshwater habitats. selected experiments native NIS under common environmental conditions detailed comparisons among traits. In addition, we explored whether different factors such relatedness, functional feeding groups, latitude, climate, experimental could linked predictive Our results show enhance consumption growth substantially increased probability establishing spreading when entering novel ecosystems. Moreover, associated predatory avoidance were more prevalent therefore favour invasive When analysed interacting taxonomically distinctive found particularly important This suggests particular should paid newly introduced for which there are no close relatives local biota. Finally, bias towards temperate regions, thus, other climatic regions needed. conclude aiming at predicting future range shifts consider trophic these indicative multiple mechanisms involved promoting invasions.
