Data from: Contrasting effects of specialist and generalist herbivores on resistance evolution in invasive plants

Zhijie Zhang, Xiaoyun Pan, Dana Blumenthal, Mark Van Kleunen, Mu Liu & Bo Li
Invasive alien plants are likely to be released from specialist herbivores and at the same time encounter biotic resistance from resident generalist herbivores in their new ranges. The Shifting Defense Hypothesis predicts that this will result in evolution of decreased defense against specialist herbivores and increased defense against generalist herbivores. To test this, we performed a comprehensive meta-analysis of 61 common garden studies that provide data on resistance and/or tolerance for both introduced and native...

Data from: Introduced garden plants are strong competitors of native and alien residents under simulated climate change

Emily Haeuser, Wayne Dawson & Mark Van Kleunen
1) Most invasive plants have been originally introduced for horticultural purposes. Still, most alien garden plants have not naturalized yet, probably due in part to inadequate climatic conditions. Climate change may alter this, but few experimental studies have addressed this for non-naturalized alien garden plants, and those that have, addressed only singular aspects of climate change. 2) In a greenhouse experiment, we examined the performance of nine non-naturalized alien herbaceous garden plants of varying climatic...

Data from: Autofertility and self-compatibility moderately benefit island colonization of plants

Mialy Razanajatovo, Mark Van Kleunen, Holger Kreft, Wayne Dawson, Franz Essl, Jan Pergl, Petr Pyšek, Marten Winter & Patrick Weigelt
Aim: The current geographical distribution of species largely reflects colonization success after natural long‐distance dispersal or introduction by humans. Plants with selfing ability should have an advantage when establishing on islands where mates and pollinators are limited (Baker's law). However, high percentages of dioecious and self‐incompatible species have been reported for some islands, possibly resulting from post‐colonization evolution. Given that such evolution is less likely to apply to alien species recently introduced to islands by...

Data from: European ornamental garden flora as an invasion debt under climate change

1.Most naturalized and invasive alien plant species were originally introduced to regions for horticultural purposes. However, many regions now face an invasion debt from ornamental alien species, which have not yet naturalized. In this regard, climate change represents a threat as it may lower the barriers to naturalization for some ornamental alien species. Identifying those species is extremely important for anticipating impending invasions. 2.To identify predictors of naturalization, we modelled the effects of climate, nursery...

Data from: Evolution of increased intraspecific competitive ability following introduction: the importance of relatedness among genotypes.

Zhijie Zhang, Fang Zhou, Xiaoyun Pan, Mark Van Kleunen, Mu Liu, Bo Li & Mark Kleunen
1.A long‐standing explanation for invasion success is that invasive plants could evolve to be more competitive following introduction. This evolution of increased competitive ability (EICA) hypothesis, however, has seldom been tested with regard to intraspecific competition. Given that plants can display different responses to related and unrelated conspecifics, the evolution of intraspecific competitive ability might be specific to genotypes of different relatedness. 2.Here, we grew five native (South American) and five introduced (North American) genotypes...

Data from: Increases and fluctuations in nutrient availability do not promote dominance of alien plants in synthetic communities of common natives

Yanjie Liu, Xiaoqi Zhang & Mark Van Kleunen
1. It is frequently thought that global environmental changes, and especially the concomitant changes in environmental variability, could further increase the success of invasive species in native resident communities. However, very few studies explicitly tested this, and it remains unknown whether invasive and non-invasive alien species respond differently to resource fluctuations in resident communities. 2. We grew ten invasive and ten non-invasive species as target species in pot-mesocosms with four different synthetic native resident communities...

Data from: Linking Darwin's naturalisation hypothesis and Elton's diversity‐invasibility hypothesis in experimental grassland communities

Yanhao Feng, Timothée Donatien Fouqueray & Mark Van Kleunen
1. Darwin's naturalisation hypothesis posing that phylogenetic distance of alien species to native residents predicts invasion success, and Elton's diversity‐invasibility hypothesis posing that diversity of native communities confers resistance to invasion, are both rooted in ideas of species coexistence. Because the two hypotheses are inherently linked, the mechanisms underlying them may interact in driving the invasion success. Even so, these links and interactions have not been explicitly disentangled in one experimental study before. 2. To...

Data from: Non-linear effects of phylogenetic distance on early-stage establishment of experimentally introduced plants in grassland communities

Eva Maria Malecore, Wayne Dawson, Anne Kempel, Gregor Müller & Mark Van Kleunen
1. The phylogenetic distance of an introduced plant species to a resident native community may play a role in determining its establishment success. While Darwin’s naturalization hypothesis predicts a positive relationship, the preadaptation hypothesis predicts a negative relationship. Rigorous tests of this now so-called Darwin’s naturalization conundrum require not only information on establishment successes but also of failures, which is frequently not available. Such essential information, however, can be provided by experimental introductions. 2. Here,...
