Abstract Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, environmental changes, including climate change, facilitate establishment. Here we provide the first global, spatial analysis of terrestrial threat from in light twenty-first century evaluate national capacities to prevent manage invasions. We find that one-sixth global land surface is highly vulnerable invasion, substantial areas developing economies...

Across large parts of the world, wildlife has to coexist with human activity in highly modified and fragmented landscapes. Combining concepts from population viability analysis spatial reserve design, this study develops efficient quantitative methods for identifying conservation core areas at large, even national or continental scales. The proposed emphasize long-term persistence, are applicable both natural landscape structures, produce a hierarchical zonation regional priority. applied...

Managed relocation (MR) has rapidly emerged as a potential intervention strategy in the toolbox of biodiversity management under climate change. Previous authors have suggested that MR (also referred to assisted colonization, migration, or translocation) could be last-alternative option after interrogating linear decision tree. We argue numerous interacting and value-laden considerations demand more inclusive for evaluating MR. The pace modern change demands making with imperfect...

Fall armyworm, Spodopterafrugiperda , is a crop pest native to the Americas, which has invaded and spread throughout sub-Saharan Africa within two years. Recent estimates of 20–50% maize yield loss in suggest severe impact on livelihoods. armyworm still infilling its potential range could other continents. In order understand fall armyworm’s year-round, global, distribution, we used evidence effects temperature precipitation life-history, combined with data African distributions construct...

Abstract Aim Correlative models that forecast extinction risk from climate change and invasion risks following species introductions, depend on the assumption species' current distributions reflect their tolerances (‘climatic equilibrium’). This has rarely been tested with independent distribution data, studies have done so focused are widespread or weedy in native range. We use data to test climatic equilibrium for a broadly representative group of species, ask whether there any general...

Managed relocation is defined as the movement of species, populations, or genotypes to places outside areas their historical distributions maintain biological diversity ecosystem functioning with changing climate. It has been claimed that a major extinction event under way and climate change increasing its severity. Projections indicating may drive substantial losses biodiversity have compelled some scientists suggest traditional management strategies are insufficient. The managed species...

To predict the threat of biological invasions to native species, it is critical that we understand how increasing abundance invasive alien species (IAS) affects populations and communities. The form this relationship across taxa ecosystems unknown, but expected depend strongly on trophic position IAS relative species. Using a global metaanalysis based 1,258 empirical studies presented in 201 scientific publications, assessed shape, direction, strength responses invader abundance. We also...

The fall armyworm (FAW), an invasive pest from the Americas, is rapidly spreading through Old World, and has recently invaded Indochinese Peninsula southern China. In FAW migrates winter-breeding areas in south into summer-breeding throughout North America where it a major of corn. Asian populations are also likely to evolve migrations corn-producing regions eastern China, they will pose serious threat food security.To evaluate invasion risk rate expansion future migratory range was modelled...

Abstract Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals produce any offspring (fertility), or number produced fertile (fecundity). This has important ecological consequences, because reproduction is ultimate measure population fitness: a reduction in reproductive output lowers growth rate and increases extinction risk. Despite this importance, there have been no large‐scale summaries evidence for effect temperature on...

Abstract Ornamental horticulture is the primary pathway for invasive alien plant introductions. We critically appraise published evidence on effectiveness of four policy instruments that tackle invasions along supply chain: pre‐border import restrictions, post‐border bans, industry codes conduct and consumer education. Effective interventions rely rigorous risk assessment high compliance. Post‐border sales bans become progressively less effective when species widespread in a region. A lack...

A key question facing conservation biologists is whether declines in species' distributions are keeping pace with landscape change, or current overestimate probabilities of future persistence. We use metapopulations the marsh fritillary butterfly Euphydryas aurinia United Kingdom as a model system to test for extinction debt declining species. derive parameters metapopulation (incidence function model, IFM) using information from 625-km2 where habitat patch occupancy, colonization, and rates...

Abstract Criticism has been levelled at climate‐change‐induced forecasts of species range shifts that do not account explicitly for complex population dynamics. The relative importance such dynamics under climate change is, however, undetermined because direct tests comparing the performance demographic models vs. simpler ecological niche are still lacking owing to difficulties in evaluating using real‐world data. We provide first comparison skill coupled ecological‐niche‐population and...

Abstract Aim Understanding the factors that govern species' geographical ranges is of utmost importance for predicting potential range shifts triggered by environmental change. Species are partially limited their tolerances to extrinsic conditions such as climate and habitat. However, they also determined capacity species disperse, establish new populations proliferate, which in turn dependent on intrinsic life‐history traits. So far, contribution driving distributions has been inconclusive,...

Abstract Many analyses of biological responses to climate rely on gridded data derived from weather stations, which differ the conditions experienced by organisms in at least two respects. First, microclimate recorded a station is often quite different that near ground surface, where many live. Second, temporal and spatial resolutions datasets stations are too coarse capture organisms. Temporally spatially have clear benefits terms reduced model size complexity, but here we argue...

Abstract Crops worldwide are simultaneously affected by weeds, which reduce yield, and climate change, can negatively or positively affect both crop weed species. While the individual effects of environmental change weeds on yield have been assessed, combined not broadly characterized. To explore simultaneous impacts with changes in climate-related conditions future food production, we conducted a meta-analysis 171 observations measuring elevated CO 2 , drought warming 23 The effect tended...
