Why Are Invasive Plants Successful?

Annual Review of Plant Biology, Год журнала: 2023, Номер 74(1), С. 635 - 670

Опубликована: Фев. 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.

A synthesis of biological invasion hypotheses associated with the introduction–naturalisation–invasion continuum

With the advent of Anthropocene, biological invasions have reached an unprecedented level, and number species introductions is still increasing in ever‐changing world. Despite major advances invasion science, significant debate lack clarity remain surrounding determinants success introduced species, magnitude dimensions their impact, mechanisms sustaining successful invasions. Empirical studies show divergent impacts alien populations on ecosystems contrasting effects biotic abiotic factors dynamics populations, which hinders creation a unified theory Compounding these issues plethora hypotheses that aim to explain success, can be unclear contradictory. We propose synthesis categorizes along timeline invasion. sorted timeline, considered population, community ecosystem levels.

Preventing and controlling nonnative species invasions to bend the curve of global freshwater biodiversity loss

Environmental Reviews, Год журнала: 2023, Номер 31(2), С. 310 - 326

The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of six principal actions needed to bend the curve in loss. This because introduction rates continue accelerate globally and where these develop invasive populations, they can have severe impacts on biodiversity. most effective management measure protect prevent introductions species. Should a be introduced, however, then its early detection implementation rapid reaction measures avoid it establishing dispersing. If are unsuccessful becomes invasive, control containment minimize further spread impact. Minimizing impact includes methods reduce invader abundance such as screening invaded sites strict biosecurity dispersing neighbouring basins.

Understanding ‘it depends’ in ecology: a guide to hypothesising, visualising and interpreting statistical interactions

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2023, Номер 98(4), С. 983 - 1002

Опубликована: Март 1, 2023

ABSTRACT Ecologists routinely use statistical models to detect and explain interactions among ecological drivers, with a goal evaluate whether an effect of interest changes in sign or magnitude different contexts. Two fundamental properties are often overlooked during the process hypothesising, visualising interpreting between drivers: measurement scale – response is analysed on additive multiplicative scale, such as ratio logarithmic scale; symmetry dependencies considered both directions. Overlooking these can lead one more three inferential errors: misinterpretation ( i ) detection (Type‐D error), ii modification (Type‐S error); iii misidentification underlying processes (Type‐A error). We illustrate each errors broad range questions applied empirical simulated data sets. demonstrate how meta‐analysis, widely used approach that seeks explicitly characterise context dependence, especially prone all errors. Based insights, we propose guidelines improve hypothesis generation, testing, visualisation interpretation ecology.

Can ecological niche models be used to accurately predict the distribution of invasive insects? A case study of Hyphantria cunea in China

Ecology and Evolution, Год журнала: 2024, Номер 14(3)

Опубликована: Март 1, 2024

Abstract In recent decades, ecological niche models (ENMs) have been widely used to predict suitable habitats for species. However, invasive organisms, the prediction accuracy is unclear. this study, we employed most maximum entropy (MaxEnt) model and ensemble (EM) Biomod2 verified practical effectiveness of ENM in predicting distribution areas insects based on true occurrence Hyphantria cunea China. The results showed that when only limited data were used, two ENMs could not effectively H. , although use global can greatly improve ENMs. When analyzing same data, Biomod2's was significantly better than MaxEnt. For long‐term predictions, area habitat predicted by much greater area; short‐term improved. Under current conditions, China 118 × 10 4 km 2 which 59.32% moderately or highly habitat. Future climate change increase China, all scenarios exceeded 355 accounting 36.98% total land This study demonstrates provides a reference management

Contemporary perspectives on the ecological impacts of invasive freshwater fishes

Journal of Fish Biology, Год журнала: 2022, Номер 103(4), С. 752 - 764

Опубликована: Окт. 8, 2022

Introductions of non-native freshwater fish continue to increase globally, although only a small proportion these introductions will result in an invasion. These invasive populations can cause ecological impacts the receiving ecosystem through processes including increased competition and predation pressure, genetic introgression transmission pathogens. Definitions impact emphasize that shifts strength are insufficient for characterizing alone and, instead, must be associated with quantifiable decline biological and/or diversity lead measurable loss or change functioning. Assessments should thus consider multiple effects potentially occur from where, example, common carp Cyprinus carpio combination bottom-up top-down that, entirety, lake stable states decreased species richness abundances biotic communities. Such far-reaching also align contemporary definitions collapse, given they involve substantial persistent declines biodiversity functions cannot recovered unaided. Thus, while not all introduced fishes become invasive, those do develop impacts, where some on functioning might sufficiently harmful considered as contributing collapse.

Studying interactions among anthropogenic stressors in freshwater ecosystems: A systematic review of 2396 multiple‐stressor experiments

Ecology Letters, Год журнала: 2024, Номер 27(6)

Опубликована: Июнь 1, 2024

Abstract Understanding the interactions among anthropogenic stressors is critical for effective conservation and management of ecosystems. Freshwater scientists have invested considerable resources in conducting factorial experiments to disentangle stressor by testing their individual combined effects. However, diversity systems studied has hindered previous syntheses this body research. To overcome challenge, we used a novel machine learning framework identify relevant studies from over 235,000 publications. Our synthesis resulted new dataset 2396 multiple‐stressor freshwater systems. By summarizing methods these studies, quantifying trends popularity investigated stressors, performing co‐occurrence analysis, produce most comprehensive overview diverse field research date. We provide both taxonomy grouping 909 into 31 classes an open‐source interactive version ( https://jamesaorr.shinyapps.io/freshwater‐multiple‐stressors/ ). Inspired our results, help clarify whether statistical detected align with interest, outline general guidelines design any system. conclude highlighting directions required better understand ecosystems facing multiple stressors.
