Correlation of native and exotic species richness: a global meta-analysis finds no invasion paradox across scales
This data set is also available on the Dryad Digital repository (link : https://doi.org/10.5061/dryad.59kv753) This dataset was created for investigating the biotic resistance hypothesis, that is, the idea that species‐rich communities are more successful at resisting invasion by exotic species than are species‐poor communities. It has been argued that native–exotic richness relationships (NERR) are negative at small spatial scales and positive at large scales, but evidence for the role of spatial scale on NERR has been contradictory. However, no formal quantitative synthesis had previously examined whether NERR is scale‐dependent across multiple studies, and previous studies on NERR have not distinguished spatial grain and extent, which may drive very different ecological processes Therefore, a global systematic review was carried out to create this dataset, which includes 204 individual cases of observational (non‐experimental) NERRs from 101 publications. Further, the above-mentioned hypotheses were investigated using a hierarchical mixed‐effects meta‐analysis, which showed that NERR was indeed highly scale dependent across studies and increased with the log of grain size. Also, no clear patterns of NERR across different spatial extents were found, suggesting that extent plays a less important role in determining NERR than does grain, although there was a complex interaction between extent and grain size. Almost all studies on NERR were found to have been conducted in North America, western Europe, and a few other regions, with little information on tropical or Arctic regions. NERR was also found to increase northward in temperate regions and vary with longitude. These results were published in the paper titled Correlation of native and exotic species richness: a global meta‐analysis finds no invasion paradox across scales (Peng et al. 2018), which represents the first global quantitative analysis of scale‐based NERR.
Community-level direct and indirect impacts of an invasive plant favour exotic over native species
<p class="CxSpFirst">1. Indirect interactions mediated by shared enemies or mutualists (i.e., apparent competition) can influence whether invasive plants harm or benefit co-occurring species. However, studies to date have largely examined single pairwise interactions, limiting our understanding of the interplay among different types of interactions and whether indirect impacts systematically favour native or exotic species. Predicting indirect interaction strength has also proven challenging, and it remains unclear whether the strengths of different indirect interactions are correlated.</p> <p class="CxSpMiddle">2. We conducted a field experiment in a grassland invaded by Scotch broom (<i>Cytisus scoparius</i>) to compare the strength of its indirect impacts, via both soil fungi or herbivores, on 21 native and exotic legume species growing in pots buried in the ground. Direct interactions of plants with soil fungi were controlled using nylon mesh pot windows of differing porosity (1 or 38 µm) to prevent or allow soil fungi hyphal growth. Arthropod herbivores were controlled through spraying pyrethrum pesticide. To assess indirect impacts, interactions were compared between plants adjacent to or 50 m away from an extensive Scotch broom invasion. We measured plant performance (survival, height, and biomass), arthropod and hare herbivory, and rhizobia nodulation.</p> <p class="CxSpMiddle">3. Despite increasing arthropod herbivory of both native and exotic plant species, Scotch broom had a net positive impact on their survival and growth, through sheltering them from abiotic stress, and indirectly via beneficial soil fungi and release from hare browsing. Soil fungi also increased arthropod herbivory, decreased rhizobia nodulation, and disproportionately promoted the growth of exotic plants. Overall, exotic plants experienced stronger interactions, which favoured them with beneficial soil fungi and rhizobia but not hare browsing. Finally, indirect interaction strength was not correlated among indirect interactions mediated by different interaction partners.</p> <p class="CxSpMiddle">4. Synthesis: We demonstrate that invaders affect their competitors through multiple interacting indirect pathways that were stronger than direct 'nurse plant' effects, emphasising the importance of a community-level approach to studying biological invasions. Exotic species experienced stronger positive and negative impacts than natives, but were facilitated overall, potentially contributing to exotic dominance in communities.</p>
Data from: Effects of native bryophytes on exotic grass invasion across an environmental gradient
Understanding the role that native biodiversity plays in controlling exotic species invasion is a critical goal in ecology. In terrestrial plant communities, most research has focused on the effects of native vascular plants on invasion by exotic vascular plants. However, in many ecosystems, native bryophytes and other non-vascular plants are common and can affect the establishment, survival and growth of vascular plants. A more complete picture of how native biodiversity affects exotic plant invasion, demands that more studies measure the effects of native bryophytes on exotic vascular plants. Moreover, there is growing realization that the effects of native species on invaders can range from negative to positive and that a complete picture of interactions between native and exotic plants requires measuring interactions in multiple environments. We used both observational and experimental studies to quantify the effects of native moss on two exotic annual grass species along a 200-m environmental gradient in a coastal dune in northern California. We found the effects of bryophytes to be species-specific and to vary with environmental context. Bryophytes facilitated the survival of one exotic grass species at both ends of the environmental gradient. For the other exotic grass species, bryophytes reduced survival at one end of the environmental gradient and had no effect at the other end. Our findings provide an important test of the effects of native bryophytes on exotic vascular plant invasion, and importantly show that these effects can vary dramatically even across local environmental gradients.

Data from: Effects of grass functional diversity on invasion success by exotic grasses in Cerrado grasslands
<ol> <li>Invasive species pose significant challenges to successful restoration efforts worldwide. A strategy to reduce invasions is to establish communities consisting of species with varied ecological strategies. These strategies typically align along the conservative and plant size axes, and more recently, along a belowground collaboration axis. However, we lack understanding of how the diverse ecological strategies of Cerrado grass species, their combinations, and their interactions with soil conditions can mitigate invasions.</li> <li>Here, we investigated how native grass communities composed of species with different ecological strategies affect the invasion success in two soil types of abandoned pastures in the Cerrado. Specifically, we tested the hypothesis that greater above- and belowground functional diversity reduces exotic species invasion. We also evaluated whether the isolated effects of native species on invasion were positive or negative.</li> <li>We installed an experiment with species richness ranging from zero to eight native grass species. In November 2019, we sowed species combinations to create communities composed by species with different ecological strategies. We quantified the aboveground biomass of exotic species as a measure of invasion. To characterize the species' ecological strategies, we measured five functional traits.</li> <li>Functional diversity of maximum height and specific root length (SRL) had the highest predictive power, however, the most parsimonious model included only SRL diversity, which represents the collaboration axis. Native aboveground biomass was also negatively related to exotic species biomass. Furthermore, invasion was greater in less stressful soil conditions but did not interact with diversity. The effect of native species varied from facilitation to competition, with the annual fast-growing native species favouring invasion.</li> <li> <em>Synthesis and applications</em>. Our results show that greater functional diversity of combined above- and belowground traits reduces invasion success, shedding light on an underexplored role of SRL diversity. The competitive and facilitative effects of different native species highlight the need for careful selection of the species to be used in restoration programs. Furthermore, the absence of interaction between diversity and soil types highlights the need for an integrated management of the functional composition and edaphic factors to increase resistance to invasion in these Neotropical grass communities.</li> </ol>
Data from: Land-use intensity and relatedness to native plants promote exotic plant invasion in a tropical biodiversity hotspot
<p>Exotic plant invasions threaten biodiversity and are costly to farmers. Land use is a major pathway promoting the spread of exotic plant species; however, little is known about the processes underlying the success of exotic plants in tropical agricultural landscapes. Focussing on the heterogeneous smallholder landscapes of north-eastern Madagascar, we studied exotic plants of understorey communities across a land-use intensity gradient from unburned lands (old-growth forests, forest fragments, and forest-derived vanilla agroforests) to burned ones (fallow-derived vanilla agroforests, woody fallows, and herbaceous fallows). </p> <p>We quantified the absolute species richness, abundance, and cover of exotic plants across land-use types and their proportional contribution to community richness, abundance, and cover as indicators of exotic plant invasion. We tested for the effects of land-use parameters, namely land-use history, canopy closure, and landscape-level forest cover, on exotic plants. Additionally, we tested whether the phylogenetic relatedness between exotic and native species in the same plot affected invasion success, testing Darwin's naturalization and pre-adaptation hypotheses. </p> <p>All indicators of exotic plant invasion were lowest in old-growth forests and forest fragments and highest in fallow-derived vanilla agroforests, woody fallows, and herbaceous fallows. Absolute and proportional exotic richness was negatively affected by canopy closure, and landscapes with high forest cover had lower proportions of exotic plant richness. High phylogenetic relatedness between exotics and natives was associated with lower proportional richness but higher proportions of exotics in abundance and cover. However, individual exotic species showed contrasting responses to land-use parameters and relatedness to natives.</p> <p>Synthesis and applications: Our results indicate that maintaining unburned lands, land-use types with dense canopies, and landscapes with high forest cover prevents the spread of exotic plants within agricultural landscapes of north-eastern Madagascar. Supporting Darwin's pre-adaptation hypothesis, exotic plants phylogenetically closely related to native plants are more likely to become successful invaders in terms of abundance and cover. Nevertheless, individual species show different responses to land-use changes and phylogenetic relatedness. Therefore, land-use decisions and management choices can be tailored to limit the spread of exotic species and to preserve native plants in this global biodiversity hotspot.</p>
Invasive plant species that experience lower herbivory pressure may evolve lower diversities of chemical defence compounds in the exotic range
<p><strong>ABSTRACT</strong></p> <p><strong>PREMISE</strong></p> <p>Invasive plant species often escape from specialist herbivore species and are likely to experience herbivory mostly from generalist herbivore species in the exotic range. Consequently, the Shifting Defence Hypothesis (SDH) predicts that invasive plants will express higher concentrations of qualitative defence compounds to deter dominant generalist herbivores in the exotic range. Here, I additionally propose a Reduced Chemical Diversity Hypothesis (RCDH), which predicts that reduced herbivory pressure will select for invasive plant genotypes that produce lower diversities of defence compounds in the exotic range.</p> <p><strong><span>METHODS</span></strong></p> <p>I tested whether: (1) Invasive <em>Brassica nigra</em> populations express a lower diversity and an overall higher concentration of glucosinolate compounds than native-range <em>B. nigra</em>; (2) <em>Brassica nigra</em> individuals that express high diversities and concentrations of glucosinolates are more attractive to specialist and deterrent to generalist herbivores; (3) Tissues of invasive <em>B. nigra </em>are less palatable to two generalist herbivores <em>Theba pisana</em> and <em>Helix aspersa</em> than tissues of native-range<em> B. nigra</em>.</p> <p><strong><span>RESULTS</span></strong></p> <p>Invasive <em>B. nigra </em>populations expressed a significantly lower diversity of glucosinolate compounds and a marginally higher concentration of total glucosinolate compounds. Leaf tissues of the invasive <em>B. nigra</em> were significantly less palatable to <em>T. pisana</em> and marginally less so to <em>H. aspersa</em>. <em>Brassica nigra</em> individuals that expressed high concentrations of total glucosinolate compounds were visited by a low diversity of generalist herbivore species in the field.</p> <p><strong><span>CONCLUSIONS</span></strong></p> <p>The biogeographical differences in glucosinolate profiles of invasive and native-range populations of <em>B. nigra</em> may be the result of differential herbivore selection pressures in the respective ranges.</p>
Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna
<p>1. Whether wild herbivores confer biotic resistance to invasion by exotic plants remains a key question in ecology. There is evidence that wild herbivores can impede invasion by exotic plants, but it is unclear whether and how this generalises across ecosystems with varying wild herbivore diversity and functional groups of plants, particularly over long-term (decadal) time frames.</p> <p>2. Using data from three long-term (13- to 26-year) exclosure experiments in central Kenya, we tested the effects of wild herbivores on the density of exotic invasive cacti, <em>Opuntia stricta</em> and <em>O. ficus-indica</em> (collectively, <em>Opuntia</em>), which are among the worst invasive species globally. We also examined relationships between wild herbivore richness and elephant occurrence probability with the probability of <em>O. stricta</em> presence at the landscape level (6,150 km<sup>2</sup>).</p> <p>3. <em>Opuntia</em> densities were 74% to 99% lower in almost all plots accessible to wild herbivores and increased more rapidly in plots excluding wild herbivores. These effects were largely driven by megaherbivores (≥1,000 kg), particularly elephants.</p> <p>4. At the landscape level, modelled <em>Opuntia</em> occurrence probability was negatively correlated with estimated species richness of wild herbivores and elephant occurrence probability. On average, O. stricta occurrence probability fell from ~0.56 to ~0.45 as wild herbivore richness increased from 6 to 10 species and fell from ~0.57 to ~0.40 as elephant occurrence probability increased from ~0.41 to ~0.84. These multi-scale results suggest that any facilitative effects of <em>Opuntia</em> by wild herbivores (e.g., seed/vegetative dispersal) are overridden by suppression (e.g., consumption, uprooting, trampling).</p> <p>5. <em>Synthesis</em>. Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions.</p>
Biogeographic differences in plant-soil biota relationships contribute to the invasion exotic range expansion of Verbascum thapsus
<ol> <li><span>Exotic plant species can evolve adaptations to environmental conditions in the exotic range. Furthermore, soil biota can foster exotic spread in the absence of negative soil pathogen-plant interactions or because of increased positive soil biota-plant feedbacks in the exotic range. Little is known, however, about the evolutionary dimension of plant-soil biota interactions when comparing native and introduced ranges.</span></li> <li><span>To assess the role of soil microbes for rapid evolution in plant invasion, we subjected <i>Verbascum thapsus</i>, a species native to Europe, to a reciprocal transplant experiment with soil and seed material originating from Germany (native) and New Zealand (exotic). Soil samples were treated with biocides to distinguish between effects of soil fungi and bacteria. Seedlings from each of five native and exotic populations were transplanted into soil biota communities originating from all populations and subjected to treatments of soil biota reduction: application of (i) fungicide, (ii) biocide, (iii) a combination of the two and (iv) control. </span></li> <li><span>For most of the investigated traits, native populations showed higher performance than exotic populations; there was no effect of soil biota origin. However, plants developed longer leaves and larger rosettes when treated with their respective home soil communities, indicating that native and exotic plant populations differed in their interaction with soil biota origin. The absence of fungi and bacteria resulted in a higher specific root length, suggesting that <i>V. thapsus</i> may compensate the absence of mutualistic microbes by increasing its root-soil surface contact.<b> </b></span></li> <li><span><b>Synthesis. </b>Introduced plants can evolve adaptations to soil biota in their new distribution range. This demonstrates the importance of biogeographic differences in plant-soil biota relationships and suggests that future studies addressing evolutionary divergence should account for differential effects of soil biota from the home and exotic range on native and exotic populations of successful plant invaders. </span></li> </ol>
Data for: Invasion by an exotic grass species homogenises native freshwater plant communities
<p>A growing body of evidence has shown that biological invasions cause shifts in species composition of communities in space and time. Although biological invasions are considered a major driver of biotic homogenisation worldwide, most previous studies are conducted at small spatial scales and over short time periods, which may have underestimated the impacts of exotic species on native communities.</p> <p>Using a unique dataset of aquatic plants sampled in 235 sites over 12 years (2007–2010 and 2015–2019) in a large reservoir (Itaipu Reservoir; 1,350 km²), we analyzed how the invasion of a non-native grass (<em>Urochloa arrecta</em>) affects the species richness, ecological uniqueness (i.e., local contribution to beta diversity – LCBD) and temporal β–diversity of native plant communities.</p> <p>From 3,934 surveyed plant communities, <em>U. arrecta</em> was recorded in 2,888 samples and it was absent from 1,046 samples. Overall, species richness and ecological uniqueness of native plant communities were markedly lower in sites invaded than non-invaded by <em>U. arrecta</em>. From 2007 to 2019, the ecological uniqueness of native plants was 60% lower in the invaded than non-invaded sites. Whereas in invaded sites the species loss was the dominant mechanism driving native communities over time, in non–invaded sites the gain of new native species was the primary mechanism underlying community trajectories. Moreover, comparing native plant communities before and after the invasion of <em>U. arrecta</em>, species richness, ecological uniqueness and species gains of native plant communities decreased, whereas species losses increased after the invasion of <em>U. arrecta</em>. Finally, the positive relationship between native biodiversity and precipitation was stronger in sites non-invaded than invaded by <em>U. arrecta</em>.</p> <p>Synthesis: Our findings provide comprehensive evidence that an invasive plant is decreasing the spatial and temporal β–diversity of native plant communities through declining species richness, rather than simply correlating with them. This suggests that<em> U. arrecta</em> is driving native plants to become less diverse and homogeneous after the invasion, both spatially and temporally. Our findings illustrate that at broad scales, aquatic plant communities may become increasingly homogeneous with the increasing number of biological invasion events taking place worldwide. </p>
Dataset for: Patterns of understory invasion in exotic, invasive timber stands
<p>Current climate and land cover change threaten global mountaintops with increased spread of invasive species. Long-established plantations of exotic and invasive trees on these mountaintops can alter their surroundings, further increasing invader-facilitated invasion. Identifying the ecological conditions that promote such specific associations can help develop better management interventions. </p> <p>The Western Ghats's Shola Sky Islands (>1400m MSL) host vast stretches of exotic and invasive tree plantations that sustain colonisation of other invasive woody, herbaceous and fern species in their understories. Here we analysed vegetation and landscape variables from 232 systematically-placed plots in randomly selected grids using NMDS and Phi Coefficient approaches, to examine patterns of association (positive interactions) between understory invasive species with specific exotic and invasive overstory species. We also conducted GLMM with zero inflation to determine the influence of environmental variables where such associations occur. </p> <p>We find that understory invasion of multiple species under the canopy of other exotic invasives is widespread across the Shola Sky Islands. Stands of Eucalyptus host the colonisation of 70% of non-native invasive species surveyed across the Shola Sky Islands. In particular, Lantana camara invasion is strongly associated with Eucalyptus stands. </p> <p><span></span></p> <p>We also found that climatic variables affect the colonisation of understorey woody invasive species, while invasion by exotic herbaceous species is associated with the density of road networks. Canopy cover impacts all invasives negatively, while incidence of fire was negatively associated with invasion by <em>Lantana</em> spp and the <em>Pteridium</em> spp. While the restoration of natural habitats largely targets the highly invasive Acacia, less invasive Eucalyptus and Pine are often not included. Our study suggests that retaining such exotic species in natural habitats, particularly protected areas, can hinder ongoing restoration efforts by facilitating further invasions by multiple woody and herbaceous species. </p>
Recolonizing native wildlife facilitates exotic plant invasion into Singapore's rain forests: Data and R script
<p>Halting biological invasions and rewilding extirpated fauna are conservation interventions to bolster biodiversity, species interactions, and ecosystems. These actions are often considered separately and the potential for reintroduced wildlife to facilitate invasive plants has been largely overlooked. Here, we investigate the role of Singapore's recolonizing native wild pigs (<em>Sus scrofa</em>) in facilitating an invasive weed <em>Miconia crenata </em>into tropical rain forests, which are normally highly resistant to invasion. We conducted line-transect surveys in 11 Singaporean rain forests and used generalized linear mixed models to consider the contribution of pigs' soil disturbances, human forest paths, and other environmental covariates, on the density of <em>M. crenata</em>. We found that <em>M. crenata</em> was more abundant at forest edges and invasion into forest interior was facilitated by pigs, paths, and canopy gaps, but that these effects were all additive, not synergistic (i.e. not multiplicative). These<span> results highlight how modern invasions are driven by multiple disturbances as well as propagule pressure (e.g. urban birds dispersing seeds at forest edges where they establish in pig soil disturbances). </span>Singapore's extensive native forest restoration efforts may have provided plentiful edge and secondary forests that are well suited to pigs and <em>M. crenata</em>, which in turn undermine the aims of fostering later-successional native plant communities. To prevent negative externalities, we suggest that plant restoration and rewilding projects consider the potential role of wildlife in facilitating non-native plants, and couple these actions with preliminary screening of unintended consequences and continued monitoring, as well as limiting human-mediated weed invasion to minimize propagule sources.</p>
Environmental variables serve as predictors of the exotic and invasive Asian longhorned tick (Haemaphysalis longicornis Neumann): an approach for targeted tick surveillance
<p>Since the 2017 discovery of established populations of the Asian longhorned tick, (<em>Haemaphysalis longicornis </em>Neumann) in the United States, populations continue to be detected in new areas. For this exotic and invasive species, capable of transmitting a diverse repertoire of pathogens and blood-feeding on a variety of host species, there remains a lack of targeted information on how to best prepare for this tick and understand when and where it occurs. To fill this gap, we conducted two years of weekly tick surveillance at four farms in Tennessee (three <em>H. longicornis</em>-infested and one without) to identify environmental factors associated with each questing life stage, to investigate predictors of abundance, and to determine the likelihood of not collecting ticks at different life stages. A total of 46,770 ticks were collected, of which 12,607 <em>H. longicornis</em> and five other tick species were identified. Overall, abundance of <em>H. longicornis </em>was associated with spring and summer seasons, forested environments, relative humidity and barometric pressure, sunny conditions, and in relation with other tick species. The likelihood of not collecting <em>H. longicornis</em> was associated with day length and barometric pressure. Additional associations for different life stages were also identified and included other tick species, climatic variables, and environmental conditions. Here, we demonstrated that environmental variables can be useful to predict the presence of questing <em>H. longicornis</em> and provide ideas on how to use this information to develop a surveillance plan for different southeastern areas with and without infestations.</p>
