Scientists' warning on invasive alien species

ABSTRACT Biological invasions are a global consequence of an increasingly connected world and the rise in human population size. The numbers invasive alien species – subset that spread widely areas where they not native, affecting environment or livelihoods increasing. Synergies with other changes exacerbating current facilitating new ones, thereby escalating extent impacts invaders. Invasions have complex often immense long‐term direct indirect impacts. In many cases, such become apparent problematic only when invaders well established large ranges. Invasive break down biogeographic realms, affect native richness abundance, increase risk extinction, genetic composition populations, change animal behaviour, alter phylogenetic diversity across communities, modify trophic networks. Many also ecosystem functioning delivery services by altering nutrient contaminant cycling, hydrology, habitat structure, disturbance regimes. These biodiversity accelerating will further future. Scientific evidence has identified policy strategies to reduce future invasions, but these insufficiently implemented. For some nations, notably Australia New Zealand, biosecurity national priority. There been successes, as eradication rats cats on islands biological control weeds continental areas. However, countries, receive little attention. Improved international cooperation is crucial biodiversity, services, livelihoods. Countries can strengthen their regulations implement enforce more effective management should address interact invasions.

Emerging Urban Forests: Opportunities for Promoting the Wild Side of the Urban Green Infrastructure

Sustainability, Journal Year: 2019, Volume and Issue: 11(22), P. 6318 - 6318

Published: Nov. 11, 2019

Many cities aim to increase urban forest cover benefit residents through the provision of ecosystem services and promote biodiversity. As a complement traditional plantings, we address opportunities associated with “emerging forests” (i.e., spontaneously developing forests in cities) for biodiversity conservation. We quantified area successional analyzed species richness native alien plants invertebrates (carabid beetles, spiders) emerging dominated by or trees, including Robinia pseudoacacia, Acer platanoides, Betula pendula. Emerging were revealed as shared habitats species. Native was not profoundly affected (co-)dominance canopy. Instead, plant richnesses positively related. Numbers endangered did differ between native- alien-dominated patches. Patterns tree regeneration indicate different trajectories novel types. conclude that these (i) provide species, some (ii) allow city dwellers experience wild nature, (iii) support arguments adapting dynamic environments. Integrating into green infrastructure is promising pathway sustainable can restoration greening approaches.

Facilitation and the invasibility of plant communities

Journal of Ecology, Journal Year: 2021, Volume and Issue: 109(5), P. 2019 - 2028

Published: Feb. 14, 2021

Abstract One of the most studied emergent functions plant community diversity is resistance diverse communities to non‐native invasions. As emphasized in this Special Feature, facilitation among native species a key mechanism by which biodiversity increases various functions, including invasion. However, when assemblages facilitate species, diversity–invasibility may be compromised. Here, I review scientific literature on invasion facilitative interactions, either and or affect invasibility. Native can directly also generate net indirect effects through suppressing that compete with invaders, but examples latter are not common. Such direct contributes ‘invasional meltdown’ restructures communities. In general, interactions between increased environmental stress, suggesting might resist more effectively environmentally favourable sites, whereas severe contribute Synthesis . each other ways, important consequences for invasibility Facilitative alter fundamental relationship invasibility, particularly habitats.

The rise of the Functional Response in invasion science: a systematic review

NeoBiota, Journal Year: 2023, Volume and Issue: 85, P. 43 - 79

Published: June 9, 2023

Predicting which non-native species will negatively impact biodiversity is a longstanding research priority. The Functional Response (FR; resource use in relation to availability) classical ecological concept that has been increasingly applied quantify, assess and compare impacts of species. Despite this recent growth, an overview applications knowledge gaps across relevant contexts currently lacking. We conducted systematic review using combination terms regarding FR invasion science synthesise scientific studies apply the approach field suggest new areas where it could have valuable applications. Trends publications about general were compared through Activity Index. Data extracted from papers reveal temporal, bibliographic, geographic trends, patterns study attributes such as type interaction habitat investigated, taxonomic groups used, context-dependencies assessed. In total, 120 included review. identified substantial unevenness reporting FRs science, despite rapidly growing number studies. To date, geographically skewed towards North America Europe, well predator-prey interactions freshwater habitats. Most focused on few invertebrates fishes. Species origin, life stage, environmental temperature complexity most frequently considered context-dependencies. conclude while thus far narrowly applied, broad potential application can be used test major hypotheses field.

Global proliferation of nonnative plants is a major driver of insect invasions

BioScience, Journal Year: 2024, Volume and Issue: 74(11), P. 770 - 781

Published: Oct. 18, 2024

Abstract Invasions by nonnative insect species can massively disrupt ecological processes, often leading to serious economic impacts. Previous work has identified propagule pressure as important driver of the trend increasing numbers invasions worldwide. In present article, we propose an alternative hypothesis—that are being driven proliferation plants, which create niches for specialists and facilitate their establishment outside native ranges where hosts planted or invasive. We synthesize mechanisms plant invasions, macroecological patterns supporting tight link between case studies having facilitated subsequent establishment. This body evidence indicates that a major invasions. Consequently, benefits limiting spread plants include averting insects spillover onto species.

The rate of non-native species introductions continues to increase, with directionality from continents islands. It is no longer single but entire networks coevolved and newly interacting continental that are establishing on consequences multispecies the population dynamics interactions native introduced will depend form trophic limitation island ecosystems. Freed biotic constraints in their range, islands experience top-down limitation, instead becoming limited by disrupting bottom-up processes dominate resource-limited This framing ecological evolutionary relationships among one another ecosystem has important for conservation.
