Published: March 11, 2025

The ecological balance and agricultural productivity of northeastern China are seriously threatened by the long-term invasion spread Asteraceae plants, which have severely disrupted region's biodiversity ecosystem stability. Ambrosia artemisiifolia L., trifida Erigeron canadensis L. Class 1 malignant invasive species widely distributed across China. In this context, we selected 36 predictor variables utilized MaxEnt model to investigate influence current climate on their distribution patterns. Using future data, projected shifts in dynamics these three for two time periods (2041–2060 2061–2080) under change scenarios (SSP126, SSP245, SSP585). demonstrated a good predictive impact, with an average area curve (AUC) 0.918. Currently, primarily found southern part However, due climatic changes, centroids gradually shifting southwest, leading increase highly suitable zones species. Moreover, trend analysis revealed that potential changes southwestern likely experience increasing various models. This study provides initial insights into change, enabling formulation plans managing preventing risks impacts

Spatial mid‐domain effect overrides climate, soil properties and microbes on a cosmopolitan non‐native plant across elevation

Oikos, Journal Year: 2025, Volume and Issue: unknown

Published: April 21, 2025

Climate warming and anthropogenic activities have led to an increase in the prevalence of non‐native plants mountainous regions that previously exhibited limited occurrences. This phenomenon has resulted detrimental effects on endemic ecosystem functions. However, variation traits successfully spread high elevations, as well underlying drivers these changes, remains poorly understood. In this study, we use Erigeron annuus , a cosmopolitan plant invaded our model explore its individual biomass pattern along 1900 m elevation gradient. We also contrast with native Artemisia lavandulifolia, which same distribution range E. . found displayed hump‐shape elevation, while A. lavandulifolia gradually decreased increasing elevation. By evaluating climate variables, soil properties, rhizosphere fungal communities spatial mid‐domain effect (i.e. geographic limitation) biomass, was primarily influenced by effect, from complex interplay climatic variables microbial communities. Our findings emphasize importance growth across indicating impact probable be greatest at mid‐elevations thus, where management priority should set. Further investigations considering more species species' will allow scrutinize vision.

Projecting global shifts in the invasive potential of Bidens pilosa L. under climate change using species distribution models

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: May 15, 2025

Invasive species pose significant threats to ecosystems by reducing biodiversity, introducing new diseases, and competing with native for resources. Bidens pilosa L., a globally invasive weed originating in tropical America, severely impacts agricultural productivity infesting 31 economically vital crops across over 40 countries. This study examined the global distribution of under current future climate scenarios. Using models occurrence data, we identified key factors influencing its spread, including temperature, precipitation, human influence. Our findings suggest likely decline suitable habitats regions an expansion into temperate regions, suitability decreasing higher temperatures. Additionally, historical reconstructions emphasize that rapid spread was facilitated maritime trade routes. Management strategies are proposed need enhanced control measures high-risk areas conservation efforts range America. Overall, this research contributes understanding dynamics B. informs proactive management mitigate ecological economic impacts.

Analysis of the Distribution Pattern of Phenacoccus manihoti in China under Climate Change Based on the Biomod2 Model

Biology, Journal Year: 2024, Volume and Issue: 13(7), P. 538 - 538

Published: July 17, 2024

The changing global climate has significantly impacted the spread of plant pests. cassava mealybug (Phenacoccus manihoti) is among most dangerous quarantine pests affecting cassavas worldwide, causing substantial losses in agricultural production and food security across several regions. Although China currently free mealybug, its proximity to affected countries extensive trade with these regions necessitate a detailed understanding pest's distribution pattern dynamic ecological niche changes. Using Biomod2 model, we selected two historical scenarios future (SSP1-2.6 SSP5-8.5) investigate patterns, potential habitats, centers, niches mealybugs China. Key environmental variables influencing were identified, including bio4, bio8, bio12, bio18, bio19. habitat mainly located provinces southern In future, suitable projected expand slightly under influence change, maintaining overall trend, but center areas will shift northward. Dynamic prediction results indicate for further expansion; however, may be unequal dissimilar invaded areas. predictions could serve as valuable reference early warning systems management strategies control introduction mealybugs.
