Biological invasions have steadily increased over recent centuries. However, we still lack a
clear expectation about future trends in alien species numbers. In particular, we do not know …

Although research on human-mediated exchanges of species has substantially intensified
during the last centuries, we know surprisingly little about temporal dynamics of alien species …

Biological invasions are a global consequence of an increasingly connected world and the
rise in human population size. The numbers of invasive alien species – the subset of alien …

Our ability to predict the identity of future invasive alien species is largely based upon knowledge
of prior invasion history. Emerging alien species—those never encountered as aliens …

The number of alien plants escaping from cultivation into native ecosystems is increasing
steadily. We provide an overview of the historical, contemporary and potential future roles of …

All around the globe, humans have greatly altered the abiotic and biotic environment with
ever-increasing speed. One defining feature of the Anthropocene epoch 1 , 2 is the erosion of …

Trade plays a key role in the spread of alien species and has arguably contributed to the
recent enormous acceleration of biological invasions, thus homogenizing biotas worldwide. …

Human-mediated transport beyond biogeographic barriers has led to the introduction and
establishment of alien species in new regions worldwide. However, we lack a global picture of …

Substantial progress has been made in understanding how pathways underlie and mediate
biological invasions. However, key features of their role in invasions remain poorly …

Rosaceae, Amaranthaceae, Pinaceae), some under-represented (eg Euphorbiaceae,
Rubiaceae), whereas the one richest in naturalized species, Compositae, reaches a value …
