Total biomass of two native and one nonnative Eugenia congeners from growth chamber experiment with site, soil microbe, and temperature treatments to test biotic interaction effects of range expansion.
To assess the potential for invasive plants to shift ranges more readily than native plant species, a growth chamber experiment was set up to monitor changes in biomass under different site, temperature, and soil biota treatments. Total biomass (above and belowground) of three Eugenia congeners was assessed by site, soil microbe, and temperature treatments. Of the three congeneric shrub species, two are native to southern and central Florida (Eugenia foetida and E. axillaris,), and one is a non-native invasive from south America (E. uniflora). We measured total biomass for these plant species in growth chambers grown under live and sterile soils from two sites within their current range, and one site in their expected range, simulating current (2010) and predicted future (2050) spring growing season temperatures in the new range. The experiments took place from 2012 - 2013 in University of Central Florida growth chambers.

Biogeographical comparison of terrestrial invertebrates and trophic feeding guilds in the native and invasive ranges of Carpobrotus edulis
Data from: Are exotic plants more abundant in the introduced versus native range?
<p>Many invasion hypotheses postulate that introducing species to novel environments allows some organisms to escape population controls within the native range to attain higher abundance in the introduced range. However, introductions may also allow inherently successful species access to new regions where they may flourish without increasing in abundance.</p> <p>To examine these hypotheses, we randomly surveyed semi-arid grasslands in the native and two introduced ranges (12,000-21,000 km2 per range) to quantify local abundance (mean cover per occupied plot) and occurrence (percentage of 1-m2 plots occupied) for 20 plant introductions that included pest and non-pest species. For each of these metrics, we evaluated relationships between abundance in the introduced versus native range 1) across all species and 2) according to designated pest status in the introduced range. We predicted that if escape from population controls primarily explained invader success, then these species would be more abundant in the introduced range; while if invader success was driven primarily by intrinsic species attributes, then their abundance would be correlated between ranges.</p> <p>Across all 20 invaders, we found that neither cover nor occurrence metrics were correlated between ranges. While cover was significantly higher in the introduced range, this result was driven by pest species. When the four pest species were excluded, cover but not occurrence was correlated between ranges. Interestingly, whereas cover of pest and non-pest species was comparably low in the native range, pest species cover increased 7-fold in the introduced range.</p> <p>Synthesis. Our results confirm previous findings that local abundance in the native range predicts local abundance in the introduced range for many introduced plants, suggesting that intrinsic species' attributes may determine most invasion outcomes. However, we also found that some species increased in local abundance in the introduced range, suggesting that changes in biogeographic context may also play an important role. While these latter species were pests, the small sample size precluded strong inferences. Determining what underlies the success of invasive pests remains elusive due to their low representation among introduced species.</p>
Data from: Soil functional responses to drought under range-expanding and native plant communities
1. Current climate warming enables plant species and soil organisms to expand their range to higher latitudes and altitudes. At the same time, climate change increases the incidence of extreme weather events such as drought. While it is expected that plants and soil organisms originating from the south are better able to cope with drought, little is known about the consequences of their range shifts on soil functioning under drought events. 2. Here, we test how range-expanding plant species and soil communities may influence soil functioning under drought. We performed a full-factorial outdoor mesocosm experiment with plant communities of range expanders or related natives, with soil inocula from the novel or the original range, with or without summer drought. We measured litter decomposition, carbon mineralization and enzyme activities, substrate-induced respiration, and the relative abundance of soil saprophytic fungi immediately after drought and at 6 and 12 weeks after rewetting. 3. Drought decreased all soil functions regardless of plant and soil origin except one; soil respiration was less reduced in soils of range-expanding plant communities, suggesting stronger resistance to drought. After rewetting, soil functioning responses depended on plant and soil origin. Soils of native plant communities with a history of drought had more litter mass loss and higher relative abundance of saprophytic fungi than soils without drought and soils of range expanders. Functions of soil from range expanders recovered in a more conservative manner than soils of natives, as litter mass loss did not exceed the control rates. At the end of the experiment, after rewetting, most soil functions in mesocosms with drought history did not differ anymore from the control. 4. We conclude that functional consequences of range expanding plants and soil biota may interact with effects of drought, and that these effects are most prominent during the first weeks after rewetting of the soil.
Not a melting pot: plant species aggregate in their non-native range
<p><b>Aim</b>: Plant species continue to be moved outside of their native range by human activities. Here, we aim at determining whether, once introduced, plants assimilate into native communities, or whether they aggregate, thus forming mosaics of native- and alien-rich communities. Alien species may aggregate in their non-native range due to shared habitat preferences, such as their tendency to establish in high-biomass, species-poor areas.</p> <p><b>Location</b>: 22 herbaceous grasslands in 14 countries, mainly in the temperate zone.</p> <p><b>Time period</b>: 2012 - 2016.</p> <p><b>Major taxa studied</b>: Plants.</p> <p><b>Methods</b>: We used a globally coordinated survey. Within this survey, we found 46 plant species, predominantly from Eurasia, for which we had co-occurrence data in their native and non-native range. We test for differences in co-occurrence patterns of 46 species, between their native (home) and non-native (away) range. We also tested whether species had similar habitat preferences, by testing for differences in total biomass and species richness of the patches species occupy in their native and non-native range.</p> <p><b>Results</b>: We found the same species to show different patterns of association, depending on whether they were in their native or non-native range. Alien species were negatively associated with native species, and aggregated instead with other alien species in species-poor, high-biomass communities in their non-native, compared to their native range.</p> <p><b>Main conclusions</b>: The strong differences between the native (home) and non-native (away) range in species co-occurrence patterns are evidence that how species associate with resident communities in their non-native range is not species-dependent, but rather a property of being away from their native range. These results thus highlight that species may undergo important ecological changes when introduced away from their native range. Overall, we show origin-dependent associations that result in novel communities in which alien-rich patches exist within a mosaic of native-dominated communities.</p>
Negative correlations between native macrophyte diversity and water hyacinth abundance are stronger in its introduced than in its native range
<p><span>Aim: </span>We tested the hypothesis that the diversity and abundance of aquatic macrophytes are negatively related with <i>Eichhornia crassipes</i> abundance in its introduced range, but not in its native range. </p> <p><span>Location: </span><span>Upper Parana River Floodplain, Brazil and Southeast China</span></p> <p><span>Methods: </span>We sampled aquatic macrophytes patches in Brazil (native range) and China (introduced range) along a biomass gradient of <i>E. crassipes</i>. For each patch, we obtained values of species richness and aquatic macrophytes percentage cover, as response variables in regression models. We also used species accumulation curves to quantify the total plot diversity in dominated and non-dominated plots for both countries. Finally, we compared the influence of <i>E. crassipes</i> dominance on community composition and beta diversity with Permanova and Permdisp, respectively.</p> <p><span>Results: </span>The regression analyses revealed a negative correlation between macrophyte richness and cover and <i>E. crassipes</i> biomass only in the introduced range. The cumulative number of species decreased at a higher extent in plots dominated by <i>E. crassipes</i> in China, compared to Brazil. Also, species composition changed and beta diversity decreased in the dominated plots in China, but not in Brazil.</p> <p><span>Main conclusions: </span>The reduction of all diversity attributes related to <i>E. crassipes</i> probably results from its engineer species role, which decreases littoral region habitat heterogeneity and affects rare species in the introduced range. Differences between countries may be associated with impacts of water hyacinth on native macrophytes since this plant grows very fast and is highly competitive. Although less probable, biotic resistance at the establishment phase of water hyacinth in sites with higher number of native species is also a possibility. Regardless of the main mechanism explaining our patterns, it is suggested that invasion by water hyacinth is a cause for concern for its higher impacts in the introduced ranges than the native ranges.</p>
Temporal dynamics and biocontrol potential of a hyperparasite on coffee leaf rust across a landscape in Arabica coffee's native range
<p>Agroforestry systems can provide habitats for rich biodiversity including multitrophic interactions, which presents opportunities to develop natural pest control. Shade coffee systems in several coffee-growing areas of the world host such unique habitats where pests and their natural enemies interact. One of the major global challenges for coffee production, coffee leaf rust caused by the fungal pathogen <i>Hemileia vastatrix</i> is attacked by the fungal hyperparasite, <i>Lecanicillium lecanii</i>. However, we lack insights in the dynamics and biocontrol potential of the hyperparasite on coffee leaf rust from landscapes in Arabica coffee's native range. To understand the temporal dynamics across landscapes and environmental drivers of the rust and hyperparasite, and the potential for biocontrol of the rust by the hyperparasite, we studied the rust and hyperparasite during the dry and wet seasons for three consecutive years at 60 sites across a gradient of coffee management in southwestern Ethiopia. We found that coffee leaf rust was more severe during the dry season, whereas the hyperparasite was more severe during the wet season in two out of three years. The rust growth rate from the wet to the dry season transition was negatively related to the hyperparasite index during the wet season, implying a potential top-down control. Coffee leaf rust was generally more severe at lower altitudes in the dry season, whereas the hyperparasite was more severe at high altitude. The rust incidence increased with management intensity, while the hyperparasite was more common under less intensive management. This study could be interesting in that it represents a landscape where Arabica coffee originated and the rust and hyperparasite might have a long co-evolutionary history. Our findings highlight the potential of the hyperparasite to suppress the rust's growth rate from the wet to dry season transition when the rust severity could otherwise be at its peak. We show that less intensively managed landscapes with dense shade levels are likely to increase hyperparasite abundance and result in an improved top-down control of the rust. However, more detailed knowledge is needed on the interaction of these species to assess its importance for reducing rust induced yield losses or the risk of rust outbreaks.</p>
Data from: Plant mutualisms with rhizosphere microbiota in introduced versus native ranges
The performance of introduced plants can be limited by the availability of soil mutualists outside their native range, but how interactions with mutualists differ between ranges is largely unknown. If mutualists are absent, incompatible or parasitic, plants may compensate by investing more in root biomass, adapting to be more selective or by maximizing the benefits associated with the mutualists available. We tested these hypotheses using seven non-agricultural species of Trifolium naturalized in New Zealand (NZ). We grew seeds from two native (Spain, UK) and one introduced (NZ) provenance of each species in glasshouse pots inoculated with rhizosphere microbiota collected from conspecifics in each region. We compared how plant biomass, degree of colonization by rhizobia and arbuscular mycorrhizal fungi (AMF), and the growth benefit associated with each mutualist differed between provenances (native and introduced populations) when grown with soil microbiota from each region. We also tested whether the growth benefit of colonization by mutualists was correlated with the extent to which alien plants were distributed in the introduced range. Rhizobia colonization was generally lower among introduced relative to native provenances. In NZ soils, 9% of all plants lacked rhizobia and 16% hosted parasitic nodules, whereas in native-range soils, there was no evidence of parasitism and all but one plant hosted rhizobia. Growth rates as a factor of rhizobia colonization were always highest when plants were grown in soil from their home range. Colonization by AMF was similar for all provenances in all soils but for four out of seven species grown in NZ soils, the level of AMF colonization was negatively correlated with growth rate. In general, introduced provenances did not compensate for lower growth rates or lower mutualist associations by decreasing shoot–root ratios. Synthesis. Despite differences between introduced and native provenances in their associations with soil mutualists and substantial evidence of parasitism in the introduced range, neither level of colonization by mutualists nor the growth benefit associated with colonization was correlated with the extent of species' distributions in the introduced range, suggesting mutualist associations are not predictive of invasion success for these species.
Data from: An invasive non-native mammal population conserves genetic diversity lost from its native range
Invasive, non-native species are one of the major causes of global biodiversity loss. Although they are, by definition, successful in their non-native range, their populations generally show major reductions in their genetic diversity during the demographic bottleneck they experience during colonization. By investigating the mitochondrial genetic diversity of an invasive non-native species, the stoat Mustela erminea, in New Zealand and comparing it to diversity in the species' native range in Great Britain, we reveal the opposite effect. We demonstrate that the New Zealand stoat population contains four mitochondrial haplotypes that have not been found in the native range. Stoats in Britain rely heavily on introduced rabbits Oryctolagus cuniculus as their primary prey and were introduced to New Zealand in a misguided attempt at biological control of rabbits, which had also been introduced there. While invasive stoats have since decimated the New Zealand avifauna, native stoat populations were themselves decimated by the introduction to Britain of Myxoma virus as a control measure for rabbits. We highlight the irony that while introduced species (rabbits) and subsequent biocontrol (myxomatosis) have caused population crashes of native stoats, invasive stoats in New Zealand, which were also introduced for biological control, now contain more genetic haplotypes than their most likely native source.
Data from: Global test of Eltonian niche conservatism of nonnative freshwater fish species between their native and introduced ranges
Despite growing evidence that biotic interactions limit the distribution of species and their potential redistribution under climate change, the recent surge of interest in niche conservatism has predominantly focused on the Grinellian (abiotic) niche, whereas few studies have attempted to quantify potential lability in the Eltonian (biotic or trophic) niche. Here, we test for conservatism in the Eltonian niche of 32 freshwater fish species between their introduced and native ranges from 435 populations across the globe. We used stable isotope data to quantify niche shifts along the horizontal (δ13C: indicating the origin of the resources consumed) and vertical (δ15N: describing the trophic position) dimensions of the isotopic niche, as well as shifts in overall isotopic niche breadth. Using an assemblage centroid standardized isotope vector analysis and controlling for phylogenetic relatedness among species, we demonstrated that introduced freshwater fishes exhibited flexibility in both resource use and trophic position that was beyond levels of natural variability observed in their native ranges. By contrast, niche breadth showed variability only within the limits recorded in native populations and varied independently from shifts in mean isotopic niche positions. Across all species and introduction histories, we found a consistent shift towards more balanced acquisition of resources with mixed origins and at intermediate trophic positions, suggesting a general mechanism by which fish species successfully establish into recipient communities. The mechanisms that promote or inhibit species from shifting their Eltonian niche remains unknown, but trophic flexibility is likely to contribute to both the success and the ecological impacts of invasive species and range shifts of native species under future global change.
