Patch size distribution affects species invasion dynamics in dendritic networks
<div class="page"> <div class="section"> <div class="layoutArea"> <div class="column"> <p>Biological invasions are globally affecting ecosystems, causing local species loss and altering ecosystem functioning. Understanding how such biological invasions occur and succeed is thus of high priority. Both local properties and the spatial network structure have been shown to be determinants of invasion success, and the identification of spatial invasion hubs directly promoting invasion dynamics is gaining attention. Spatial dynamics, however, could also indirectly alter invasion success by shaping pre- invasion local community structure: in many ecosystems, such as riverine networks, regional properties such as patch size distribution are known drivers of local community structures, which themselves may affect the establishment success of invading species. Using microcosm experiments in dendritic networks, we disentangled how inherent patch size distribution and dispersal along specific network topologies shaped local resident communities, and, subsequently, affected the establishment success of invading species. After controlling for regional-scale effects of connectivity on pre-invasion diversity, we find that patch size distributions independently shaped pre-invasion community diversity and invasion success, with no direct effect of pre-invasion diversity on invasion success. Our results suggest that 1) landscape configuration plays an underestimated role in invasion success and that 2) invasion success should follow predictable landscape-scale patterns in riverine networks given non-random patch-size distribution.</p> </div> </div> </div> </div>
Dataset for: Differential responses to fertilization and competition among invasive, non-invasive alien and native Bidens species
<p class="manuscript">Comparative studies of invasive, non-invasive alien, and native congenic plant species can identify plant traits that drive invasiveness. In particular, functional traits associated with rapid growth rate and high fecundity likely facilitate invasive success. As such traits often exhibit high phenotypic plasticity, characterizing plastic responses to anthropogenic environmental changes such as eutrophication and disturbance is important for predicting the invasive success of alien plant species in the future. Here, we compared trait expression and phenotypic plasticity at the species level among invasive, non-invasive alien, and native <i>Bidens</i> species. Plants were grown under nutrient addition and competition treatments, and their functional, morphological, and seed traits were examined. Invasive <i>B. frondosa</i> exhibited higher phenotypic plasticity in most measured traits than did the alien non-invasive <i>B. pilosa</i> or native <i>B. bipinnata</i>. However, differential plastic responses to environmental treatments rarely altered the rank of trait values among the three <i>Bidens</i> species, except for the number of inflorescences. The achene size of <i>B. frondosa</i> was larger, but its pappus length was shorter than that of <i>B. pilosa</i>. Two species demonstrated opposite plastic responses of pappus length to fertilization. These results suggest that the plasticity of functional traits does not significantly contribute to the invasive success of <i>B. frondosa</i>. The dispersal efficiency of <i>B. frondosa</i> is expected to be lower than that of <i>B. pilosa</i>, suggesting that long-distance dispersal is likely not a critical factor in determining invasive success.</p>
Data from: Invasive herbaceous respond more negatively to elevated ozone concentration than native species
<p>Aim: Many studies show that increase in ground-level ozone (O<sub>3</sub>) has adverse effects on plant growth. Due to high phenotypic plasticity, invasive species is considered to be more adaptable to elevated O3 than native species. This idea is only tested by the very limited studies comparing invasive weeds with crops. However, whether it holds remains unclear when comparing invasive species with their co-occurring native species in natural systems.</p> <p>Location: China</p> <p>Methods: We performed an open-top chamber experiment growing six congeneric pairs of invasive and native species with and without competition under ambient (approximately 43 ppb) and elevated O<sub>3</sub> (approximately 89 ppb) concentrations to test whether the growth responses to elevated O<sub>3</sub> concentrations differ between invasive and native species.</p> <p>Results: Our results revealed that elevated O<sub>3</sub> had a significant negative effect on both invasive and native species. In particular, elevated O<sub>3</sub> reduced the aboveground biomass and damaged the leaves of invasive species significantly more than those of native species.</p> <p>Main conclusions: Our study indicates that elevated O<sub>3</sub> concentration has a stronger adverse effect on invasive species than on native species. Therefore, increasing O<sub>3</sub> pollution might suppress plant invasion, and thus invasive species might expand their distribution more easily to the area with lower O<sub>3</sub> pollution in the future.</p>

Prioritizing terrestrial invasive alien plant species for management in urban ecosystems
<p>1. Invasive alien plant species (IAPs) in urban areas can have detrimental effects on biodiversity, ecosystem services and human well-being. Urban areas are complex social management mosaics with high land-use diversity, complex land tenure patterns, and many different stakeholder groups, some of which derive benefits from invading species. Urban conservation practitioners face complex decisions about which IAPs require management. Yet most IAPs prioritization frameworks have been designed for and implemented in natural or rural areas and are generally inadequate for guiding effective and sustainable interventions in urbanized areas.</p> <p>2. We modified an existing prioritization scheme to develop a framework for prioritizing terrestrial IAPs in urban areas which applies evidence-based (data-driven) and stakeholder-based (local knowledge) assessments to score and rank alien plant species in terms of their priority for management using an objective set of criteria.</p> <p>3. The framework consists of forty-six criteria, grouped into eight modules which assess invasion status, habitat requirements, biological characteristics, dispersal ability, distribution, impact (positive and negative), and potential for control for each alien plant species under consideration.</p> <p>4. We use the city of Toronto, Canada as a case study to test our framework – a list of 50 IAPs were effectively scored and ranked in order of high to low priority for control. Species with the highest <i>total prioritization scores</i> were <i>Vincetoxicum</i> <i>rossicum</i> (Dog Strangling Vine), <i>Convolvulus</i> <i>arvensis</i> (Field Bindweed) and <i>Taraxacum</i> <i>officinale</i> (Common Dandelion) (ranked 1, 2 and 3, respectively).</p> <p>5. Many of the identified high priority species align with the those previously flagged as of management concern by conservation practitioners, but also include those that are not actively managed due to their perceived lower ecological impacts. These species still require high resource investment for other objectives such as aesthetics. This highlights the complexity of alien plant species management in urban areas.</p> <p>6.<i> Synthesis and applications. </i>Prioritizing invasive alien plants for management in urban areas is particularly challenging due to often conflicting ecological, economic, and social objectives. We use available evidence and local stakeholder knowledge to develop an objective and systematic prioritization tool which can assist conservation practitioners in selecting priority species for management action in complex urban landscapes.</p>
Multiple modes of selection can influence the role of phenotypic plasticity in species' invasions: Evidence from a manipulative field experiment
<p><span>In exploring the roles of phenotypic plasticity in the establishment and early evolution of invading species, little empirical attention has been given to the importance of correlational selection acting upon suites of functionally related plastic traits in nature. We illustrate how this lack of attention has limited our ability to evaluate plasticity's role during invasion and also, the costs and benefits of plasticity. We addressed these issues by transplanting clones of European-derived <i>Plantago lanceolata</i> L. genotypes into two temporally variable habitats in the species' introduced range in North America. Phenotypic selection analyses were performed for each habitat to estimate linear, quadratic, and correlational selection on phenotypic trait values and plasticities in the reproductive traits: flowering onset, spike and scape lengths. Also, we measured pairwise genetic correlations for our "colonists". Results showed that 1) correlational selection acted on trait plasticity after transplantation, 2) selection favored certain combinations of genetically correlated and uncorrelated trait values and plasticities, 3) Using signed, instead of absolute, values of plasticity in analyses facilitated the detection of correlational selection on trait value-plasticity combinations and their adaptive value. Based on our results, we urge future studies on species invasions to: 1) measure correlational selection and 2) retain signed values of plasticity in order to better discriminate between adaptive and maladaptive plasticity. </span></p>
Data from: Population genomics of Sitka black-tailed deer supports invasive species management and ecological restoration on islands
<p>Invasive mammals represent a critical threat to island biodiversity; eradications can result in ecological restoration yet may fail in the absence of key population parameters. Over-browsing by invasive Sitka black-tailed deer (<em>Odocoileus hemionus sitkensis</em>) is causing severe ecological and cultural impacts across the Haida Gwaii archipelago (Canada). Previous eradication attempts demonstrate forest regeneration upon deer removal, but reinvasion reverses conservation gains. Here we use restriction-site associated DNA sequencing (12,947 SNPs) to investigate connectivity and gene flow of invasive deer (n=181) across 15 islands, revealing little structure throughout Haida Gwaii and identifying the large, central island of Moresby (>2,600 km2) as the greatest source of migrants. As a result, the archipelago itself should be considered the primary eradication unit, with the exception of geographically isolated islands like SGang Gwaay. Thus, limiting eradications to isolated islands combined with controlled culling and enhanced biosecurity may be the most effective strategies for achieving ecological restoration goals.</p>
Richness, not evenness, of invasive plant species promotes invasion success into native plant communities via selection effects
<p>Native plant communities are often invaded by multiple alien species. It is still unclear how increasing diversity of alien invasive species suppresses the growth of native species and thus contributes to invasion success. In the subtropical monsoon region of Southeast China, we experimentally created a native plant community with 18 herbaceous species. One week later, we let it be invaded by either zero (controls without invasion), one, two, four or eight alien plant species, with either high or low species evenness. After a four-month growth period we harvested the aboveground biomass of each species. We found that increasing invasive species richness significantly increased invasive plant biomass, the biomass of all invasive and native plant species within the community, and invasion success (the ratio of invasive plant biomass to the biomass of all native and invasive plants), but it did not significantly reduce native plant biomass. Experimentally manipulating invasive species evenness did not influence invasion success and did not show any differential suppression effects on native plants. One invasive species, Sesbania cannabina, became dominant in terms of plant biomass, irrespective of its proportion in the alien plant mixtures. Throughout this experiment, effects of invasive species richness on invasion success were mainly due to such selection effects among the invasive species. On the other hand, the unchanged biomass of native species under increasing invasive plant richness suggests the presence of at least partly complementary resource niches between invasive and native species.</p>
Data from: Foraging decisions with conservation consequences: Interaction between beavers and invasive tree species
<p><span>Herbivore species can either hinder or accelerate the invasion of woody species through selective utilization. Therefore, an exploration of foraging decisions can contribute to the understanding and forecasting of woody plant invasions. Despite the large distribution range and rapidly growing abundance of beaver species across the Northern Hemisphere, only a few studies focus on the interaction between the beaver and invasive woody plants. </span></p> <p><span>We collected data on the woody plant supply and utilization at 20 study sites in Hungary, at two fixed distances from the water. The following parameters were registered: taxon, trunk diameter, type of utilization, and carving depth. Altogether 5401 units (trunks and thick branches) were identified individually. We developed a statistical protocol that uses a dual approach, combining whole-database and transect-level analyses to examine foraging strategy.</span></p> <p><span>Taxon, diameter, and distance from water all had a significant effect on foraging decisions. The order of preference for the four most abundant taxa was: <em>Populus </em>spp. (softwood), <em>Salix </em>spp. (softwood), <em>Fraxinus pennsylvanica</em></span> <span>(invasive hardwood),<em> Acer negundo</em> (invasive hardwood). The diameter influenced the type of utilization, as units with greater diameter were rather carved or debarked than felled. According to the central-place foraging strategy, intensity of the foraging decreased with the distance from the water, while both the taxon and diameter selectivity increased. This suggests stronger modification of the woody vegetation directly along the waterbank, together with a weaker impact further from the water. </span></p> <p><span>In contrast to invasive trees, for which utilization occurred almost exclusively in the smallest diameter class, even the largest softwood trees were utilized by means of carving and debarking. This may lead to the gradual loss of softwoods or the transformation of them into shrubby form. After the return of the beaver, mature stages of softwood stands and thus the structural heterogeneity of floodplain woody vegetation could be supported by the maintenance of sufficiently large active floodplains. </span></p> <p><span>The beaver accelerates the shift of the canopy layer's species composition towards invasive hardwood species, supporting the enemy release hypothesis. However, the long-term impact will also depend on how plants respond to different types of utilization and on their ability to regenerate, which are still unexplored issues in this environment. Our results should be integrated with knowledge about factors influencing the competitiveness of the studied native and invasive woody species to support floodplain conservation and reconstruction.</span></p>
