Frameworks used in invasion science: progress and prospects

Wilson, John R.U. ; Bacher, Sven ; Daehler, Curtis C. ; Groom, Quentin J. ; Kumschick, Sabrina ; Lockwood, Julie L. ; Robinson, Tamara B. ; Zengeya, Tsungai A. ; Richardson, David M.

In: NeoBiota, 2020, vol. 62, p. 1–30

Our understanding and management of biological invasions relies on our ability to classify and conceptualise the phenomenon. This need has stimulated the development of a plethora of frameworks, ranging in nature from conceptual to applied. However, most of these frameworks have not been widely tested and their general applicability is unknown. In order to critically evaluate frameworks in...

Cross-fertilizing weed science and plant invasion science to improve efficient management: A European challenge

Müller-Schärer, Heinz ; Sun, Yan ; Chauvel, Bruno ; Karrer, Gerhard ; Kazinczi, Gabriella ; Kudsk, P. ; Lansink Oud, A. G. J. M. ; Schaffner, Urs ; Skjoth, C. A. ; Smith, M. ; Vurro, M. ; de Weger, L. A. ; Lommen, Suzanne T. E.

In: Basic and Applied Ecology, 2018, vol. 33, p. 1–13

Both weed science and plant invasion science deal with noxious plants. Yet, they have historically developed as two distinct research areas in Europe, with different target species, approaches and management aims, as well as with diverging institutions and researchers involved. We argue that the strengths of these two disciplines can be highly complementary in implementing management...

Plant invasions, generalist herbivores, and novel defense weapons

Schaffner, Urs ; Ridenour, Wendy M. ; Wolf, Vera C. ; Bassett, Thomas ; Müller, Caroline ; Müller-Schärer, Heinz ; Sutherland, Steve ; Lortie, Christopher J. ; Callaway, Ragan M.

In: Ecology, 2011, vol. 92, no. 4, p. 829-835

One commonly accepted mechanism for biological invasions is that species, after introduction to a new region, leave behind their natural enemies and therefore increase in distribution and abundance. However, which enemies are escaped remains unclear. Escape from specialist invertebrate herbivores has been examined in detail, but despite the profound effects of generalist herbivores in natural...
