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.

The importance of assessing positive and beneficial impacts of alien species

NeoBiota, Journal Year: 2020, Volume and Issue: 62, P. 525 - 545

Alien may decrease or increase attributes ecosystems (e.g. total biomass diversity), thus causing negative positive environmental impacts. also negatively positively impact linked to local human communities number people involved in a given activity). Ethical societal values contribute define these socio-economic as deleterious beneficial. Whilst most focuses effects taxa, some recognise their beneficial activities.

Invasion impacts and dynamics of a European‐wide introduced species

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(15), P. 4620 - 4632

Published: May 15, 2022

Globalization has led to the introduction of thousands alien species worldwide. With growing impacts by invasive species, understanding invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, dynamics have been assumed follow an "invasion curve" (S-shaped curve available area invaded over time), but this dynamic lacked empirical testing using large-scale data neglects consider invader abundances. We propose "impact describing generated time based on cumulative To test curve's applicability, we used data-rich New Zealand mud snail Potamopyrgus antipodarum, one most damaging freshwater invaders that almost all Europe. Using long-term (1979-2020) abundance environmental collected across 306 European sites, observed P. antipodarum generally increased through time, with slower population growth at higher latitudes lower runoff depth. Fifty-nine percent these populations followed impact curve, characterized first occurrence, exponential growth, then saturation. This behaviour is consistent boom-bust dynamics, as saturation occurs due a rapid decline in time. Across estimated peaked approximately two decades after detection, rate progression along was influenced local abiotic conditions. The S-shaped may be common among many undergo complex dynamics. provides potentially unifying approach advance could inform timely management actions mitigate ecosystems economies.

The TOP-100 most dangerous invasive alien species in Northern Eurasia: invasion trends and species distribution modelling

NeoBiota, Journal Year: 2023, Volume and Issue: 82, P. 23 - 56

Published: Feb. 2, 2023

Northern Eurasia is extensive and includes terrestrial aquatic ecosystems that cover several natural zones access to the seas of three oceans. As a result, it has been invaded by numerous invasive alien species (IAS) over large temporal spatial scales. The purpose this research was assess invasion trends construct distribution models for Russian TOP-100 most dangerous IAS. Environmentally suitable regions IAS were established based on attribute databases, datasets 169,709 occurrence records (SOR) raster layers environmental variables using modelling (MaxEnt). objectives (1) create databases SOR in Russia; 2) determine pathways, residence time, donor invasions; (3) main types distributions their relation time; (4) distinguish with highest richness have strong impact Russia. We found although invasions date back 400 years, number naturalized increased non-linearly past 76 years. list mainly represented unintentionally introduced (62%) which are characterized different introduction pathways. Species revealed 56 distributed locally, 26 regionally 18 widespread local, regional or times 55, 126 190 respectively. local can expand range into more extensively (expected increase 32%) than only 7%). procedure identifying hot/cold spots locations allowed us identify Our results integrated database we created provide framework studying scales be used development management plans

Understanding the complex dynamics of zebra mussel invasions over several decades in European rivers: drivers, impacts and predictions

The zebra mussel Dreissena polymorpha is one of the most successful, notorious, and detrimental aquatic invasive non‐native species worldwide, having invaded Europe North America while causing substantial ecological socio‐economic impacts. Here, we investigated spatiotemporal trends in this species' invasion success using 178 macroinvertebrate abundance time series, containing 1451 records D. collected across nine European countries between 1972–2019. Using these raw (absolute) data, examined drivers occurrences relative abundances within communities.

Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology

NeoBiota, Journal Year: 2025, Volume and Issue: 97, P. 215 - 235

Invasive alien (IA) predators pose significant threats to native ecosystems, often leading profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused the NCE of predator-induced stress from one crayfish species, noble ( Astacus astacus ), compared danube Pontastacus leptodactylus ) two IA signal Pacifastacus leniusculus spinycheek Faxonius limosus damselfly Ischnura elegans . We investigated cue effect egg traits as well potential carry-over stage larval stage. hypothesised that cues would lead more pronounced negative crayfish, due an evolutionary history interaction recognition these threats. Unexpectedly, cues, caused significantly higher mortality prolonged developmental times, particularly while had weaker, yet, still effects.

Abstract Aim The establishment and spread of invasive alien species may be influenced by several mutually interacting factors, whose understanding is paramount to develop effective biosecurity policies. However, studies focused on modelling spatially explicit patterns future invasion risk have so far response climate change impacts, while land‐use has been neglected. We investigated how the interplay between could affect potential distribution dispersal corridors four squirrels introduced Europe ( Sciurus carolinensis, Callosciurus finlaysonii , erythraeus Eutamias sibiricus ). Location Methods Our study was conducted in Italy. used Species Distribution Models circuit theory methods test whether scenarios based only predict a different effect range connectivity squirrel populations, compared that include both changes. Results Scenarios predicted increase high geographic stability (>50%) for most species, with different, yet limited, effects corridors. Conversely, showed loss extent low (<50%) species. Main conclusions considering provide predictions overturn those including change. global warming alone would lead considerable expansion all when added, suitable habitat squirrels, hence limiting their expansion. recommend using multiple drivers models obtain reliable implementing policies related
