For themutualistic interaction between the aphidMetopeurum fuscoviride Stroyan (Homoptera:Aphididae) and the ant Lasius niger L. (Hymenoptera: Formicidae) it has been shown that ant-tended aphids develop faster, reproduce at a higher rate, and live longer than aphids not tended by ants. We used electrical penetration graphs (EPG) to investigate if behavioural patterns differ between...

More than “100 worst” alien species in Europe

Nentwig, Wolfgang ; Bacher, Sven ; Kumschick, Sabrina ; Pyšek, Petr ; Vilà, Montserrat

In: Biological Invasions, 2018, vol. 20, no. 6, p. 1611–1621

“One hundred worst” lists of alien species of the greatest concern proved useful for raising awareness of the risks and impacts of biological invasions amongst the general public, politicians and stakeholders. All lists so far have been based on expert opinion and primarily aimed at representativeness of the taxonomic and habitat diversity rather than at quantifying the harm the alien...
