Environmental issues have become one of the important topics affecting China and world. As world’s most populous country second-largest economy, China’s environmental conditions significant impacts on global ecosystems sustainable development. To accurately determine relationship between economic development environment, explore non-coordination spatial characteristics two, promote regional This study is based land-use data from four periods: 1990, 2000, 2010, 2020. It uses dynamic measurement value equivalent method to changes measure ecosystem services in Central Yunnan Urban Agglomeration. At same time, degree model hotspot analysis tools identify Ecosystem Service Value (Gross Domestic Product), them. The research results show that: (1) main types include cultivated land, forest grassland, which account for more than 90% total proportion. land with a small proportion region are water areas, construction unused land. (2) level service presents changes: fluctuating increase, decrease, continuous decrease. distribution shows obvious heterogeneity, overall presenting pattern “low middle, high around.” (3) average index 1990 2020 0.591, 0.635, 0.584, 0.565, showing coordinated coupling type. space “high central western regions, low northeastern southern regions.” (4) hotspots mainly concentrated northwest regions Agglomeration, while coldspots distributed northeastern, western, regular agglomeration distribution. suggests that it necessary balance coordinate environment.

Management Measures and Trends of Biological Invasions in Europe: A Survey‐Based Assessment of Local Managers

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

Published: Jan. 1, 2025

Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions people worldwide. However, the effectiveness of invasive alien species (IAS) management measures progress toward achieving biodiversity targets remain uncertain due limited nonuniform data availability. Management success is usually assessed at local level documented in technical reports, often written languages other than English, which makes such notoriously difficult collect large geographic scales. Here we present first European assessment how managers perceive trends IAS mitigate biological invasions. We developed structured questionnaire translated into 18 disseminated it regional Europe. received responses from 1928 participants 41 countries, including 24 Union (EU) Member States. Our results reveal substantial efforts monitoring control, with plants being primary focus. Yet, there general perception an increase numbers, occupied areas, impacts across environment taxonomic groups, particularly plants, over time. This perceived consistent both EU non-EU respondents countries demonstrating more certainty their responses. also indicate lack on vertebrates invertebrates, reflecting need for targeted knowledge sharing between policymakers countries. Overall, our study suggests that Europe's current strategies insufficient substantially reduce by 2030 hence meet Kunming-Montreal Global Biodiversity Framework target.

Riverine Barrier Removals Could Proliferate Biological Invasions

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Multiple stressors, such as pollution, climate change, invasive species and fragmentation, threaten global ecosystems, requiring holistic management actions. Freshwater ecosystems are disproportionately biodiverse particularly impacted by fragmentation biological invasions. Artificial barriers, dams weirs, long-standing features of landscapes, with a divergence views on their benefits disbenefits. Recognition the negative impacts barriers river continuum native biota, for migratory aquatic species, has led to rapid rate barrier removals in recent decades, especially North America Europe. However, since rise riverine construction centuries ago, invasion rates have concurrently surged. can paradoxically slow spread through freshwaters, removal efforts thus risk proliferating that disperse rapidly connected habitats. Despite well-intended plans restoration removals, subsequent colonisation been largely overlooked. This presents 'connectivity conundrum': intuitively addresses issues migrations dispersals, but could perversely exacerbate species. Basin-scale data collection around short- long-term will help underpin future projects maximise potential beneficial outcomes

Latitude and Community Diversity Primarily Explain Invasion Patterns of Widespread Invasive Plants in Small, Subtropical Lakes

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(3)

Published: March 1, 2025

ABSTRACT Within the study of aquatic invasive species, small ecosystems are often neglected, despite representing most global freshwater bodies. This uses community composition and environmental geographic factors to explain occurrence species in lakes southeastern United States. Four widespread States were selected as focus this study: Alternanthera philoxeroides , Cyperus blepharoleptos Panicum repens Triadica sebifera . The plant communities surveyed using littoral zone point sampling. Generalized linear models for each fit with probability ( P occ ) response variable Secchi depth, diversity α‐ diversity), richness, perimeter, latitude, longitude potential predictors; all predictors subjected model selection define best‐fit models. All strongly predictive area under receiver operating characteristic curve values > 0.80. Plant was positively correlated A. P. T. Latitude negatively Perimeter related depth C. Although latitude commonly predictive, usually explained by multiple predictors, suggesting that these relationships best factors.

This review focuses on the alternative uses of Elodea nuttallii (Planch.) H.St.John biomass. is as an aquatic invasive alien species classified in EU a Species Union Concern. Its dense monospecific stands affect both ecosystems and human activities, thereby requiring specific monitoring management measures. The handling E. has high economic cost, biomass removed from natural environments considered mere waste product. need to implement circular economy, reducing preserving capital, led research for reuse valorisation waterweed biomasses, such nuttallii. critically assesses feasibility potential applications various sectors, including bioenergy production, extraction metabolites, fertilization. Out more than 200 articles 1965 2023, only 16 were found deal with use harvested biomass, all within last 12 years. highlights that underrepresented topic scientific literature, therefore industrial sectors. Studies biogas production are most represented have shown chemical composition suitable energy but better suited additional feedstock other biomasses already used this purpose. New cost-effective applications, animal feed biosorbent, should be further addressed. By investigating contributes development sustainable practices would turn costly into valuable resource.

Published: Jan. 1, 2024

Quarantine plant bacteria (QPB) are significant component of invasive alien species that result in substantial economic losses and serious environmental damage. Here, a colorimetric aptasensor has been proposed based on the sandwich structure an autonomous screening aptamer cascaded catalytic strategy nanozyme for on-site detecting Xanthomonas hyacinthi, type QPB, natural environments. The self-screened obtained through SELEX can bind with binding sites surface viable organism high affinity specificity, which guarantees selectivity aptasensor. As important part aptasensor, MIL-88-NH2(Fe) not only acts as multifunctional carrier both aptamers glucose oxidase, but also catalyzes enzyme-like reaction because tremendous specific area, plentiful amino excellent peroxidase-like activity. present hyacinthi trigger formation occurrence cascade reaction, enabling detection UV spectra naked eyes. presents low limit 2 cfu/mL wide linear range 10 -107 cfu/mL. Compared to traditional methods QPB detection, reasonable design, convenience significantly improve efficiency contribute protection.
