The North American common ragweed, Ambrosia artemisiifolia, which produces highly allergenic pollen, is invasive in different parts of the world, including Europe. In 2013, common ragweed in northern Italy was found attacked by another accidentally introduced species, the North American leaf beetle Ophraella communa, which is used for biological control of common ragweed in China. Since the...

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...

Explaining variability in the production of seed and allergenic pollen by invasive Ambrosia artemisiifolia across Europe

Lommen, Suzanne T. E. ; Hallmann, Caspar A. ; Jongejans, Eelke ; Chauvel, Bruno ; Leitsch-Vitalos, Melinda ; Aleksanyan, Alla ; Tóth, Peter ; Preda, Cristina ; Šćepanović, Maja ; Onen, Huseyin ; Tokarska-Guzik, Barbara ; Anastasiu, Paulina ; Dorner, Zita ; Fenesi, Annamária ; Karrer, Gerhard ; Nagy, Katalin ; Pinke, Gyula ; Tiborcz, Viktor ; Zagyvai, Gergely ; Zalai, Mihály ; Kazinczi, Gabriella ; Leskovšek, Robert ; Stešević, Danijela ; Fried, Guillaume ; Kalatozishvili, Levani ; Lemke, Andreas ; Müller-Schärer, Heinz

In: Biological Invasions, 2017, p. 1–17

To better manage invasive populations, it is vital to understand the environmental drivers underlying spatial variation in demographic performance of invasive individuals and populations. The invasive common ragweed, Ambrosia artemisiifolia, has severe adverse effects on agriculture and human health, due to its vast production of seeds and allergenic pollen. Here, we identify the scale and...

In: Journal of Ecology, 2015, vol. 103, no. 4, p. 1069–1098

This account presents information on all aspects of the biology of Ambrosia artemisiifolia L. (Common ragweed) that are relevant to understanding its ecology. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral...
