Predicting the invasion range for a highly polyphagous and widespread forest herbivore
Here we compare the environmental niche of a highly polyphagous forest Lepidoptera species, the winter moth (Operophtera brumata), in its native and invaded range. During the last…

Assessing the probability of freedom from pine wood nematode based on 19 years of surveys
Many quarantine pests, such as the pine wood nematode (PWN, Bursaphelenchus xylophilus), are surveyed annually in all EU countries. Although a lot of resources are spent in the su…
Perceptions of alien plants and animals and acceptance of control methods among different societal groups
Biological invasions are a widespread phenomenon and cause substantial impacts on the natural environment and human livelihoods. Thus, the European Union (EU) recently adopted Reg…
Trait–environment relationships of plant species at different stages of the introduction process
The success of alien plant species can be attributed to differences in functional traits compared to less successful aliens as well as to native species, and thus their adaptation…
Simultaneous detection of native and invasive crayfish and Aphanomyces astaci from environmental DNA samples in a wide …
Crayfish of North American origin are amongst the most prominent high-impact invasive invertebrates in European freshwaters. They contribute to the decline of European native cray…
Spatiotemporal patterns of non-native terrestrial gastropods in the contiguous United States
The contiguous United States (CONUS) harbor a significant non-native species diversity. However, spatiotemporal trends of some groups such as terrestrial gastropods (i.e., land sn…
How dense is dense? Toward a harmonized approach to characterizing reefs of non-native Pacific oysters – with considera…
Pacific oysters Crassostrea (Magallana) gigas have been successfully invading ecosystems worldwide. As an ecosystem engineer, they have the potential to substantially impact on ot…
Invasive alien species add to the uncertain future of protected areas
Establishing and managing protected areas (national parks, nature reserves and other sites of conservation value) represent the most common approach to conserving species and ecos…
Biogeographical comparison of terrestrial invertebrates and trophic feeding guilds in the native and invasive ranges of…
