Biological invasions are a global phenomenon that threatens biodiversity, and few, if any,
ecosystems are free from alien species. The outcome of human‐mediated introductions is …

Exotic species are a growing global ecological threat; however, their overall effects are
insufficiently understood. While some exotic species are implicated in many species …

Non‐indigenous species (NIS) and hypoxia (< 2 mg O2 l− 1) can disturb and restructure
aquatic communities. Both are heavily influenced by human activities and are intensifying …

Biological invasions are considered one of the most important drivers of biodiversity loss.
Here we use a before-after-control-impact (BACI) design to investigate the impact of …

Invasive ecosystem engineers can have far-reaching effects on systems, especially if they
provide structure where none was before. The non-native seaweed Gracilaria …

Aim Biotic homogenization (BH), a reduction in the distinctness of species composition
between geographically separated ecological communities in a region, is an important but …

Biotic homogenization—increasing similarity of species composition among ecological
communities—has been linked to anthropogenic processes operating over the last century …

Non-native foundation species occasionally invade habitats occupied by native foundation
species. Little is known, however, about reciprocal effects of native and non-native …

Habitat‐forming invasive species have complex impacts on native communities. Positive
above ground and negative below ground impacts are reported, suggesting that habitat …

We conducted a bibliographic survey, adding 69 taxa to a published list of 277 seaweeds,
thereby updating the total worldwide list of non-native and cryptogenic seaweeds to 346 …
