Addressing context dependence in ecology

Trends in Ecology & Evolution, Journal Year: 2021, Volume and Issue: 37(2), P. 158 - 170

Published: Oct. 30, 2021

Context dependence is widely invoked to explain disparate results in ecology. It arises when the magnitude or sign of a relationship varies due conditions under which it observed. Such variation, especially unexplained, can lead spurious seemingly contradictory conclusions, limit understanding and our ability transfer findings across studies, space, time. Using examples from biological invasions, we identify two types context resulting four sources: mechanistic interaction effects; apparent arise presence confounding factors, problems statistical inference, methodological differences among studies. Addressing critical challenge ecology, essential for increased prediction.

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.

Solutions in microbiome engineering: prioritizing barriers to organism establishment

The ISME Journal, Journal Year: 2021, Volume and Issue: 16(2), P. 331 - 338

Abstract Microbiome engineering is increasingly being employed as a solution to challenges in health, agriculture, and climate. Often manipulation involves inoculation of new microbes designed improve function into preexisting microbial community. Despite, increased efforts microbiome inoculants frequently fail establish and/or confer long-lasting modifications on ecosystem function. We posit that one underlying cause these shortfalls the failure consider barriers organism establishment. This key challenge focus macroecology research, specifically invasion biology restoration ecology. adopt framework from summarizes establishment three categories: (1) propagule pressure, (2) environmental filtering, (3) biotic interactions factors. suggest most neglected factor we recommend number actions accelerate solutions.

Native diversity buffers against severity of non-native tree invasions

Nature, Journal Year: 2023, Volume and Issue: 621(7980), P. 773 - 781

Published: Aug. 23, 2023

Determining the drivers of non-native plant invasions is critical for managing native ecosystems and limiting spread invasive species1,2. Tree in particular have been relatively overlooked, even though they potential to transform economies3,4. Here, leveraging global tree databases5-7, we explore how phylogenetic functional diversity communities, human pressure environment influence establishment species subsequent invasion severity. We find that anthropogenic factors are key predicting whether a location invaded, but severity underpinned by diversity, with higher lower Temperature precipitation emerge as strong predictors strategy, invading successfully when similar community cold or dry extremes. Yet, despite these ecological forces determining evidence patterns can be obscured activity, signal areas proximity shipping ports. Our perspective highlights presence, role invasions.

Biodiversity increases resistance of grasslands against plant invasions under multiple environmental changes

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: May 27, 2024

Abstract Biodiversity often helps communities resist invasion. However, it is unclear whether this diversity–invasion relationship holds true under environmental changes. Here, we conduct a meta-analysis of 1010 observations from 25 grassland studies in which plant species richness manipulated together with one or more change factors to test invasibility (measured by biomass cover invaders). We find that biodiversity increases resistance invaders across various conditions. the positive effect on invasion strengthened experimental warming, whereas weakened experimentally imposed drought. When multiple are simultaneously, strengthened. Overall, show invasions Therefore, investment protection and restoration native not only important for prevention current conditions but also continued global change.

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

Oikos, Journal Year: 2024, Volume and Issue: 2024(4)

Published: Jan. 22, 2024

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. Meta‐regression models revealed non‐significant both at level for majority countries, except France (significant decreasing trend) Hungary (marginally positive trend). At level, number over followed a flat‐top bell‐shaped distribution, with steep increase 1973–1989 by plateau phase prior to significantly declining post‐1998. series climatic hydromorphological site‐specific characteristics uninvaded sites from two periods (1998–2002; 2011–2015), found that native richness, abundance, distance next barrier, elevation were associated occurrence .

One-Health is an umbrella term that integrates the health of environment, humans and non-human animals. This approach applied here to elucidate impact non-native invasive species on aquaculture food security. Despite inherent biases against these species, a better understanding their characteristics allows for identification those greatest concern, minimizing risk shortages infectious diseases. review summarises positive negative impacts delineating specific areas they may impact.

Published: Nov. 6, 2022

Abstract Aim Invasive alien species are a growing problem worldwide due to their ecological, economic and human health impacts. The “killer shrimp” Dikerogammarus villosus is notorious invasive amphipod from the Ponto‐Caspian region that has invaded many fresh brackish waters across Europe. Understandings of large‐scale population dynamics highly impactful invaders such as D. lacking, inhibiting predictions impact efficient timing management strategies. Hence, our aim was assess trends well its impacts in freshwater rivers streams. Location Methods We analysed 96 European time series between 1994 2019 identified relative abundance (i.e. dominance %) series, set site‐specific characteristics identify drivers determinants changes invasion using meta‐regression modelling. also looked at spread over space estimate speed (km/year) investigated on recipient community metrics abundance, taxa richness, temporal turnover, Shannon diversity Pielou evenness) generalized linear models.

Nevertheless, increased all frequency occurrences (used proxy for invader spread) described by Pareto distribution, whereby we estimated lag phase introduction spatial expansion) approximately 28 years, followed gradual increase before new declined rapidly long term. change associated with decreased turnover diversity. Main Conclusion Our results show well‐established significantly alters ecological communities. However, multidecadal prior observed expansion suggests initial introductions cryptic, thus signalling need more effective early detection methods.
