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: Targeted re-sequencing of coding DNA sequences for SNP discovery in non-model species

Daniel W. Förster, James K. Bull, Dorina Lenz, Marijke Autenrieth, Johanna L.A. Paijmans, Robert H.S. Kraus, Carsten Nowak, Helmut Bayerl, Ralph Kuehn, Alexander P. Saveljev, Magda Sindičić, Michael Hofreiter, Krzysztof Schmidt, Joerns Fickel, Johanna L. A. Paijmans & Robert H. S. Kraus
Targeted capture coupled with high throughput sequencing can be used to gain information about nuclear sequence variation at hundreds to thousands of loci. Divergent reference capture makes use of molecular data of one species to enrich target loci in other (related) species. This is particularly valuable for non-model organisms, for which often no a priori knowledge exists regarding these loci. Here, we have used targeted capture to obtain data for 809 nuclear coding DNA sequences...

Data from: Across a migratory divide: divergent migration directions and non-breeding grounds of Eurasian reed warblers revealed by geolocators and stable isotopes

Petr Procházka, Vojtěch Brlík, Elizabeth Yohannes, Bert Meister, Jürgen Auerswald, Mihaela Ilieva & Steffen Hahn
Migratory divides represent narrow zones of overlap between parapatric populations with distinct migration directions and, consequently, expected divergent non-breeding distributions. The composition of the mixed population at a migratory divide and the corresponding non-breeding ranges remain, however, unknown for many Palaearctic-African migrants. Here, we used light-level geolocation to track migration direction and non-breeding grounds of Eurasian reed warblers (Acrocephalus scirpaceus) from three breeding populations across the species’ migratory divide. Moreover, by using feathers grown at...

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: Long-term experimental hybridisation results in a heterologous transition and the evolution of a new sex chromosome in swordtail fish

Paolo Franchini, Julia C. Jones, Peiwen Xiong, Susanne Kneitz, Zachariah Gompert, Wesley C. Warren, Ronald B. Walter, Axel Meyer & Manfred Schartl
The remarkable diversity of sex determination mechanisms known in fish may be fuelled by exceptionally high rates of sex chromosome turnovers or transitions. However, the evolutionary causes and genomic mechanisms underlying this variation and instability are yet to be understood. Here we report on an over 30-year evolutionary experiment in which we tested the genomic consequences of hybridisation and selection between two Xiphophorus fish species with different sex chromosome systems. We find that introgression and...

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: Large birds travel farther in homogeneous environments

Marlee A. Tucker, Olga Alexandrou, , Keith L. Bildstein, Katrin Böhning-Gaese, Chloe Bracis, John N. Brzorad, Evan R. Buechley, David Cabot, Justin M. Calabrese, Carlos Carrapato, André Chiaradia, Lisa C. Davenport, Sarah C. Davidson, Mark Desholm, Christopher R. DeSorbo, Robert Domenech, Peter Enggist, William F. Fagan, Nina Farwig, Wolfgang Fiedler, Christen H. Fleming, Alastair Franke, John M. Fryxell, Clara García-Ripollés … & João Paulo Silva
Aim: Animal movement is an important determinant of individual survival, population dynamics, and ecosystem structure and function. Yet it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside of the migratory period, we examined how the distribution of resources affect the movement patterns of both large terrestrial birds (e.g., raptors, bustards, hornbills) and waterbirds (e.g., cranes, storks, ducks,...

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

Emily Haeuser, Wayne Dawson, Wilfried Thuiller, Stefan Dullinger, Svenja Block, Oliver Bossdorf, Marta Carboni, Luisa Conti, Iwona Dullinger, Franz Essl, Günther Klonner, Dietmar Moser, Tamara Muenkemueller, Madalin Parepa, Matthew V. Talluto, Holger Kreft, Jan Pergl, Petr Pyšek, Patrick Weigelt, Marten Winter, Martin Hermy, Sebastiaan Van Der Veken, Cristina Roquet & Mark Van Kleunen
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: The scent of attractiveness: levels of reproductive hormones explain individual differences in women’s body odour

Janek Lobmaier, Urs Fischbacher, Urs Wirthmüller, Daria Knoch & Janek S. Lobmaier
Individuals are thought to have their own distinctive body odour which reportedly plays an important role in mate choice. In the present study we investigated individual differences in body odours of women and examined whether some women generally smell more attractive than others or whether odour preferences are a matter of individual taste. We then explored whether levels of reproductive hormones explain women’s body odour attractiveness, to test the idea that body odour attractiveness may...

Data from: Evolutionary divergence of 3’ UTRs in cichlid fishes

Peiwen Xiong, Darrin C. Hulsey, Axel Meyer & Paolo Franchini
Background: Post-transcriptional regulation is crucial for the control of eukaryotic gene expression and might contribute to adaptive divergence. The three prime untranslated regions (3’ UTRs), that are located downstream of protein-coding sequences, play important roles in post-transcriptional regulation. These regions contain functional elements that influence the fate of mRNAs and could be exceptionally important in groups such as rapidly evolving cichlid fishes. Results: To examine cichlid 3’ UTR evolution, we 1) identified gene features in...

Data from: Hybridization could be a common phenomenon within the highly diverse lizard genus Liolaemus

Melisa Olave, Luciano J. Avila, , Mariana Morando & Jack W. Sites
Hybridization is likely to occur more often between closely related taxa that have had insufficient time to diverge to the point of reproductive incompatibility; hybridization between deeply divergent lineages is rare. In squamate reptiles, hybridization has been proposed as a possible explanation for the extensive paraphyly observed in mitochondrial gene trees in several species complexes of the South American lizard genus Liolaemus. One of the best-documented cases is within the L. boulengeri and L. rothi...

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,...

Data from: Temporal activity patterns of predators and prey across broad geographic scales

Stephen D.J. Lang, Richard P. Mann, Damien R. Farine & Stephen D J Lang
Predators and prey are locked in an evolutionary arms race that shapes their behaviour and life history. Predators target prey vulnerabilities to maximise hunting success, while prey trade-off foraging against predation avoidance. Though studies have demonstrated how predation risk can alter how prey allocate daily foraging effort, little work has considered the implications of this temporal component of behaviour from a predator’s perspective, or assessed its influence on broad-scale predator-prey interactions. We develop a method...

Data from: Agouti-related peptide 2 facilitates convergent evolution of stripe patterns across cichlid fish radiations

Claudius F. Kratochwil, Yipeng Liang, Jan Gerwin, Joost M. Woltering, Sabine Urban, Frederico Henning, Gonzalo Machado-Schiaffino, C. Darrin Hulsey & Axel Meyer
The color patterns of African cichlid fishes provide notable examples of phenotypic convergence. Across the more than 1200 East African rift lake species, melanic horizontal stripes have evolved numerous times. We discovered that regulatory changes of the gene agouti-related peptide 2 (agrp2) act as molecular switches controlling this evolutionarily labile phenotype. Reduced agrp2 expression is convergently associated with the presence of stripe patterns across species flocks. However, cis-regulatory mutations are not predictive of stripes across...

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...
