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