The number of alien plants escaping from cultivation into native ecosystems is increasing steadily. We provide an overview the historical, contemporary and potential future roles ornamental horticulture in plant invasions. show that currently at least 75% 93% global naturalised flora grown domestic botanical gardens, respectively.

Assembly of nonnative floras along elevational gradients explained by directional ecological filtering

Proceedings of the National Academy of Sciences, Journal Year: 2010, Volume and Issue: 108(2), P. 656 - 661

Published: Dec. 27, 2010

Nonnative species richness typically declines along environmental gradients such as elevation. It is usually assumed that this because few invaders possess the necessary adaptations to succeed under extreme conditions. Here, we show nonnative plants reaching high elevations around world are not highly specialized stress tolerators but with broad climatic tolerances capable of growing across a wide elevational range. These results contrast patterns for native species, and they can be explained by unidirectional expansion from anthropogenic sources at low progressive dropping out narrow amplitudes—a process call directional ecological filtering. Independent data confirm generalists have succeeded in colonizing more environments higher elevations. suggest invasion resistance conferred conditions particular site determined pathways introduction species. In future, increased direct ecophysiological mountain could increase risk invasion. As well providing general explanation importance traits phenotypic plasticity many invasive concept filtering useful understanding initial assembly some floras latitudes.

Integrative invasion science: model systems, multi‐site studies, focused meta‐analysis and invasion syndromes

New Phytologist, Journal Year: 2013, Volume and Issue: 200(3), P. 615 - 633

Published: July 24, 2013

Invasion science is a very active subdiscipline of ecology. However, some scientists contend that theoretical integration has been limited and predictive power remains weak. This paper, focusing on plants, proposes new multi-pronged research strategy builds recent advances in invasion science. More intensive studies particular model organisms ecosystems are needed to improve our understanding the full suite interacting factors influence invasions ('model system research'). At same time, comparative across many study systems essential for unravelling context-dependencies insights emerge from ('multi-site studies'); quantitative synthesis based large datasets should be constrained well-defined domains ('focused meta-analysis'). We also suggest ways better information about species biology ecosystem characteristics ('invasion syndromes'). expect resulting theory will need conceived as somewhat heterogeneous conglomerate elements varying generality power: laws apply well-specified domains, general concepts frameworks can guide thinking management, in-depth knowledge drivers invasions.

Why Are Invasive Plants Successful?

Annual Review of Plant Biology, Journal Year: 2023, Volume and Issue: 74(1), P. 635 - 670

Published: Feb. 8, 2023

Plant invasions, a byproduct of globalization, are increasing worldwide. Because their ecological and economic impacts, considerable efforts have been made to understand predict the success non-native plants. Numerous frameworks, hypotheses, theories advanced conceptualize interactions multiple drivers context dependence invasion with aim achieving robust explanations predictive power. We review these from community-level perspective rather than biogeographical one, focusing on terrestrial systems, explore roles intrinsic plant properties in determining species invasiveness, as well effects biotic abiotic conditions mediating ecosystem invasibility (or resistance) evolutionary processes. also consider fundamental influences human-induced changes at scales ranging local global triggering, promoting, sustaining invasions discuss how could alter future trajectories.

Rapid upwards spread of non-native plants in mountains across continents

Nature Ecology & Evolution, Journal Year: 2023, Volume and Issue: 7(3), P. 405 - 413

Published: Jan. 26, 2023

Abstract High-elevation ecosystems are among the few worldwide that not yet heavily invaded by non-native plants. This is expected to change as species expand their range limits upwards fill climatic niches and respond ongoing anthropogenic disturbances. Yet, whether how quickly these changes happening has only been assessed in a isolated cases. Starting 2007, we conducted repeated surveys of plant distributions along mountain roads 11 regions from 5 continents. We show over 5- 10-year period, number increased on average approximately 16% per decade across regions. The direction magnitude upper limit shifts depended elevation all Supported null-model approach accounting for chance alone, found greater than upward at lower/mid elevations least seven After dependence, significant were detected further three (revealing evidence 10 regions). Together, our results environments becoming increasingly exposed biological invasions, emphasizing need monitor prevent potential biosecurity issues emerging high-elevation ecosystems.

Effects of Invasive Plants on Arthropods

Conservation Biology, Journal Year: 2014, Volume and Issue: 28(6), P. 1532 - 1549

Published: July 26, 2014

Non-native plants have invaded nearly all ecosystems and represent a major component of global ecological change. Plant invasions frequently change the composition structure vegetation communities, which can alter animal communities ecosystem processes. We reviewed 87 articles published in peer-reviewed literature to evaluate responses arthropod functional groups non-native invasive plants. Total abundance arthropods decreased 62% studies increased 15%. Taxonomic richness 48% 13%. Herbivorous response plant 17%, likely due direct effects diversity. Predaceous 44% studies, may reflect indirect reductions prey. Twenty-two percent documented increases predators, changes that improved mobility, survival, or web-building for these species. Detritivores 67% litter decaying vegetation; no this group. Although many researchers examined on arthropods, sizeable information gaps remain, specifically regarding how influence habitat dietary requirements. Beyond this, ability predict populations associated with could be by adopting more mechanistic approach. Understanding will critically inform conservation virtually biodiversity processes because so organisms depend as prey their roles, including pollination, seed dispersal, decomposition. Given short generation times respond rapidly change, ideal targets restoration activities.
