This North American species is the most widely spread freshwater crayfish worldwide, and is one of the worst invasive species due to its severe impacts on the structure and functioning of freshwater ecosystems. The results of the study may help to prevent the further expansion of the red swamp crayfish and to avoid potential future invasions.

Understanding factors driving successful invasions is one of the cornerstones of invasion biology. Bird invasions have been frequently used as study models, and the foundation of current knowledge largely relies on species purposefully introduced during the 19th and early 20th centuries in countries colonized by Europeans. However, the profile of exotic bird species has changed radically in the last decades. Here, the role of the main drivers of invasion success on the establishment and...
