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

Global Ecology and Biogeography, Journal Year: 2021, Volume and Issue: 30(8), P. 1572 - 1582

Published: May 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, Journal Year: 2022, Volume and Issue: 28(9), P. 1832 - 1849

Published: June 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.

Invasive Plant Species Demonstrate Enhanced Resource Acquisition Traits Relative to Native Non-Dominant Species but not Compared with Native Dominant Species

Diversity, Journal Year: 2024, Volume and Issue: 16(6), P. 317 - 317

Published: May 26, 2024

Invasive plant species are often characterized by superior resource acquisition capabilities compared with native species, contributing to their success in new environments. However, the dominance of these varies, and not all invasive become dominant, nor uniformly vulnerable competitive exclusion. In this study, we analyzed 19 functional traits across 144 herbaceous Guangzhou, China. The studied included 31 dominant (IDS), non-dominant (INS), 63 (NDS), (NNS). Our findings reveal no significant differences between IDS INS, indicating a broad trait similarity within categories. Pronounced similarities NDS suggest an ecological equivalency that facilitates successful integration competition habitats. Notable several key traits—height, leaf thickness, water content, stoichiometry, photosynthetic rate, use efficiency, nitrogen efficiency—indicate superiority utilization for over NNS. These distinctions vital understanding mechanisms driving crucial developing strategies manage impact on ecosystems.
