Propagule pressure increase and phylogenetic diversity decrease community’s susceptibility to invasion
2017
Background Invasions pose a large threat to native species, but the question of why some species are more invasive, and some communities more prone to invasions than others, is far from solved. Using 10 different three-species bacterial communities, we tested experimentally if the phylogenetic relationships between an invader and a resident community and the propagule pressure affect invasion probability. Results We found that greater diversity in phylogenetic distances between the members of resident community and the invader lowered invasion success, and higher propagule pressure increased invasion success whereas phylogenetic distance had no clear effect. In the later stages of invasion,…

Using ten different three-species bacterial communities, we tested experimentally if the phylogenetic relationships between an invader and a resident community and propagule pressure affect invasion probability. We found that greater diversity in phylogenetic distances between the resident community members and the invader lowered invasion success, and higher propagule pressure increased invasion success whereas phylogenetic distance had no clear effect.
