Plant regulatory lists in the United States are reactive and inconsistent

Journal of Applied Ecology, Journal Year: 2021, Volume and Issue: 58(9), P. 1957 - 1966

Abstract Global invasive species introductions are rising, necessitating coordinated regulatory strategies within and across national borders. Although states nations address their unique priorities using plant regulations, these regulations most likely to reduce introduction spread if they consistently enacted political borders proactively restrict early in the invasion process. Further, a unified landscape is particularly important given imminent range infilling large‐scale climate‐driven shifts of species. In United States, federal state several hundred noxious taxa an effort negative impacts. Using for lower 48 we assessed consistency among regulated based on similarities adjacent states’ lists.

Conflicting interests and growing importance of non‐indigenous species in commercial and recreational fisheries of the Mediterranean Sea

Fisheries Management and Ecology, Journal Year: 2022, Volume and Issue: 29(2), P. 169 - 182

Abstract Non‐indigenous species (NIS) are spreading and reshaping Mediterranean Sea biological communities fishery resources. The present study used fisheries data structured interviews to assess the impacts of NIS on recreational commercial fishers in Cyprus. that have been Cyprus for more than two decades were mostly perceived by local as native, with high market value considered be beneficial, venomous or poisonous deleterious. Pufferfishes (Tetraodontidae) identified causing significant economic damage, which undermines sustainability fishing sector. most popular highly priced rabbitfishes ( Siganus spp.). In terms landings, six non‐indigenous taxa contributed over a quarter total landing half during summer season. results emphasised multifaceted interactions sector, how policy objectives may not align social interests.

Macroscale analyses suggest invasive plant impacts depend more on the composition of invading plants than on environmental context

Global Ecology and Biogeography, Journal Year: 2023, Volume and Issue: 32(11), P. 1964 - 1976

Published: Aug. 29, 2023

Abstract Aim Native biodiversity is threatened by the spread of non‐native invasive species. Many studies demonstrate that invasions reduce local but we lack an understanding how impacts vary across environments at macroscale. Using ~11,500 vegetation surveys from ecosystems United States, quantified relationship between plant cover and native diversity varied different compositions invading plants (measured richness evenness) environmental contexts productivity human activity). Location Continental States. Time Period Surveys 1990s‐present. Major Taxa Studied Terrestrial communities. Methods We fit mixed effects models to understand richness, evenness with cover. tested this when interacted evenness, activity. Results Across communities greater had lower higher suggesting rare can be lost while dominant decline in abundance. The community was not associated Negative associations were strongest areas low characterizing invaded a plant. Main Conclusions Non‐native provides first approximation invasion on diversity, magnitude impact depended evenness. Relationships consistent strength continental scale gradients Therefore, macroscale, likely depend more characteristics plants, presence invader, than context.

Combining local, landscape, and regional geographies to assess plant community vulnerability to invasion impact

Abstract Invasive species science has focused heavily on the invasive agent. However, management to protect native also requires a proactive approach resident communities and features affecting their vulnerability invasion impacts. Vulnerability is likely result of factors acting across spatial scales, from local regional, it combined effects these that will determine magnitude vulnerability. Here, we introduce an analytical framework quantifies scale‐dependent impact biological invasions richness shape species–area relationship (SAR). We leveraged newly available, biogeographically extensive vegetation data U.S. National Ecological Observatory Network assess plant community as function scales. analyzed more than 1000 SARs widely distributed USA along environmental gradients under different levels non‐native cover. Decreases in were consistently associated with cover, but was compromised only at relatively high After accounting for variation baseline ecosystem diversity, net primary productivity, human modification, ecoregions colder wetter most vulnerable losses level, while warmer areas susceptible landscape level. document how cross‐scale heterogeneous pattern This could not be predicted by analyses any single scale, underscoring importance Simultaneously assessing differences between distinct local, landscape, regional scales provided outputs can used inform policy aimed reducing invasions.

Abstract With increasing impacts of climate change observed across ecosystems, there is an urgent need to consider in all future environmental policy. But existing policy and management might be slow respond this challenge, leading missed opportunities incorporate into practice. Furthermore, invasive species threats continue rise interact with change—exacerbating negative impacts. Enabling natural resource managers individuals proactive about climate-driven creates a win–win for conservation. Recommendations include expanding information sharing borders, supporting screening regulation high-risk on the horizon, incentivizing individual actions that reduce ecological In addition, risk should considered when crafting mitigation adaptation compounding stressors ecosystems. As we develop much-needed tools harm, must combined invasions change.

Soil nitrogen cycling in forests invaded by the shrub Rosa multiflora: importance of soil moisture and invasion density

Biogeochemistry, Journal Year: 2024, Volume and Issue: 167(3), P. 301 - 319

Published: March 23, 2024

Abstract Invasive plants often alter ecosystem function and processes, especially soil N cycling. In eastern United States forests, the shrub Rosa multiflora (“rose”) is a dominant invader, yet potential effects on cycling are poorly understood. Moreover, invasive plant management can impact by decreasing uptake disturbing soil. The objectives of this study were to evaluate along gradient rose invasion (observational) investigate changes (manipulative) under four different strategies: (1) do nothing (the control), (2) removal, (3) removal followed native seed mix addition, (4) mix, chipped stem addition. We selected three forest sites experiencing Low, Medium, or High amount invasion, measured in early (June) late (September) growing seasons. found was immobilized June mineralized September. One year after experimental management, alone had no effect compared control plots, but addition stems reduced early-season nitrification our Medium site. Our findings suggest that may increase rates when soils dry, which occur more frequently with future climate change. responds differentially following most noticeably moderate invasion.
