Simple Summary Aggressive invasive species can outcompete native species in contests
over resources, which can lead to the exclusion of a native species by the invader. Invasive …

In novel communities, a rising number of new and emerging invasive species interact with
resident species, some of which are non‐native themselves. We implemented an innovative …

Aggressive encounters between invasive and native species are considered a key threat
associated with the spread of invasive species. Extrinsic factors such as habitat complexity …

Biological invasions are a major cause of biodiversity loss and, coupled with climate
change, will likely have detrimental impacts for native species and the functioning of …
