Abstract Ornamental horticulture is the major pathway of non‐native plant species introductions worldwide. Historic nursery catalogues capture a long‐term view introduction effort arising from garden plantings and are powerful resource for understanding why some introduced ornamental subsequently jump fence. Analyses historic can help us understand reasons failed invasions as well successfully naturalize or invade. We used New Zealand 1860s to 1990s patterns invasions, successful naturalization invasion. Together with data on several horticulturally relevant traits, we boosted classification model predict likelihood A species' maximum height, its frequency in catalogues, family‐level global rate were most influential variables. Naturalized generally taller, more frequently offered sale, belonged families higher rates than those that had not naturalized. Other traits such cold hardiness shade tolerance significantly different between naturalized non‐naturalized but contributed somewhat overall fit. By contrast, our predictions would become invasive poor, without any robust relationships covariates. This indicates factors drive transition may be determined by characteristics habitats they Species incorrectly predicted have sufficient opportunity do so pose greater risk naturalizing future. provides an avenue identifying future enabling proactive management monitoring these concern.

Wisdom of the crowd: evidence for density-dependent species fitness in Hyptis suaveolens (L.) Poit.

Abstract Background Biological invasions pose severe threats to global biodiversity and human well-being. Invading populations often experience negative growth rates during the ‘lag phase’, leading Allee effects, a density-dependent phenomenon. effects reduce species fitness or plant performance due low-density populations. The rapid spread range expansion of an invader, Hyptis suaveolens (L.) Poit. has been reported have impacts on local in invaded regions Vindhyan highlands, India. present study examines varied population densities H. its vegetative trait performance, reproductive output, regulations. Understanding relationship between density modulation ability at fine coarse scales could help strategize for management. Methods was conducted habitats Population divided into low-, medium-, high-density groups. Plant assessed two scales—fine scale scale. traits, growth, output were estimated as traits (PlTs) patch (PaTs) plasticity response index (PI) also among three densities. Results showed that PlTs-vegetative such height, biomass, number seeds, significantly different across densities, with medium-density individuals showing maximum height biomass exhibiting higher seeds per plant. PaTs analysis revealed similar medium- populations, whereas low- PI values PlTs low, medium, high plastic responses, while exhibited low responses. Conclusions concludes exhibits As increases, grow more rapidly, resulting denser These can negatively impact recipient and, if left unchecked, seed production. suggests areas should be considered priority developing efficient cost-effective management strategies. emphasizes importance incorporating dynamics invasion studies predicting high-risk/priority strategizing invasive

Abstract Background Global risk assessment of invasive weeds is a proactive strategy for identifying high-risk species and regions, predicting invasion rates extents, evaluating harmful impacts on native biodiversity, agriculture, ecosystems. In this study, distribution modeling was used to assess the global Ardisia elliptica , highly tropical shrub South Southeast Asia that in other parts world, under current climate future change scenarios [shared socioeconomic pathways (SSPs) SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5] environmental variables, including land use cover change, soil moisture, carbon, pH, human influence index. Results Our study revealed annual precipitation, index, precipitation wettest month contributed significantly MaxEnt model, with estimated contributions 31.35%, 22.76%, 14.77%, respectively.

Botanic gardens play key roles in the regional distribution of first records of alien plants in China

Global Ecology and Biogeography, Год журнала: 2021, Номер 30(8), С. 1572 - 1582

Опубликована: Май 18, 2021

Abstract Aim Plant invasions pose a serious risk to biodiversity, and living collections in botanic gardens are recognized as potentially important source of alien plant introductions. However, it is not yet known how the risks from compare with other socioeconomic environmental factors influencing regional distribution Location China. Time period 1840–2018. Major taxa studied All vascular plants. Method We compiled dataset locations first records introduction pathways for 454 species naturalized China used boosted regression trees evaluate roles number, size age gardens, local climate, native richness trade on total number plants at both city province level. Results Botanic large played most role scale. importance depended pathway species. The introduced horticulture were more influenced by attributes gardens. Moreover, agriculture associated climatic variables, accidentally strongly shaped trade. Main conclusions Our results highlight facilitating introductions across continent. Given rapid rise Asia since 1950, our point these potential hotspots future invasions. should implement screening procedures assess invasion arising their undertake systematic surveys plantings evidence naturalization.

Are species more harmful in their native, neonative or alien range? Insights from a global analysis of bark beetles

Diversity and Distributions, Год журнала: 2022, Номер 28(9), С. 1832 - 1849

Опубликована: Июнь 30, 2022

Abstract Aim Anthropogenic environmental modifications such as climate or land‐use change are causing species to move on their own beyond native ranges. As this phenomenon will increase in the near future, it is crucial determine whether range‐expanding species, neonatives, more less likely than and alien impact recipient ecosystems. Here, we compared magnitudes of bark beetle from native, neonative ranges, simultaneously. Location Global. Methods We formulated four general scenarios about magnitude impacts different ranges (native, alien) based hypotheses commonly used invasion biology. tested these globally Dendroctonus beetles, asking they have most harmful Impacts reported literature were assessed with IUCN Environmental Impact Classification for Alien Taxa (EICAT). Results found that beetles cause followed by while lowest. This indicates dissimilar environment range, lower probability high‐impact magnitudes. Our results align several non‐exclusive hypotheses, e.g. pre‐adaptation habitat filtering, do not support others, enemy release Darwin’s naturalization. The also contrast previous studies vertebrates plants, which no mixed differences biogeographic origin. Main conclusions analysis suggests like other keystone abundant generally when introduced novel environments due biotic resistance lack pre‐adaptation. Research management implications regarding populations discussed.
