Complex biotic networks of invaders and their new environments pose immense challenges
for researchers aiming to predict current and future occupancy of introduced species. This …

Since alien species may threaten native ecosystems when becoming invasive, one of the
main challenges is try to predict their potential spread. Despite bees are essential pollinators …

Background Invasive species are increasingly driving biodiversity decline, and knowledge of
colonization dynamics, including both drivers and dispersal modes, are important to prevent …

Climate change is a key threat to pollination networks and has already caused shifts in the
distribution and phenology of many bee species. Predictions based on species distribution …

Highlights•Over 80 different species of bees have been introduced around the world.•Non-
native bees range from solitary to social, and managed to unmanaged.•There exists a …

The ecological impacts of alien species invasion are a major threat to global biodiversity.
The increasing number of invasion events by alien species and the high cost and difficulty of …

Andrena hattorfiana is a rare solitary bee which has declined during the last decades
throughout western Europe. It is specialised to forage pollen from plants of the family …

Simple Summary Climate change exacerbates the threat of biological invasions by
increasing climatically suitable regions for species to invade outside of their native range …

Simple Summary Alien bee species could have detrimental effects; in particular, they may
compete with native bee species for floral resources or nesting sites. Here, we first studied …

Citizen science, a practice of public participation in scientific projects, is popular in Western
countries, however, it is still a relatively novel approach in Southeast Europe. In this region …
