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. Results Population varied series. 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.

Present status, future trends, and control strategies of invasive alien plants in China affected by human activities and climate change

Invasive alien plants (IAPs) have serious environmental and economic impacts, especially in vulnerable areas of China. However, IAP richness distribution patterns, their driving factors, the dynamic shifts potential remain elusive. We assessed patterns drivers using 402 IAPs recorded China at 88 926 occurrence points, then predicted areas. The results show that hotspots were mainly located southeastern China, coastal South East large inland cities. Population density, gross domestic product (GDP), four climate variables associated with precipitation temperature jointly influenced pattern all IAPs. Specifically, population density GDP impacted narrow‐range IAPs, GDP, distance to nearest national highway, five affected widespread Only contributed significantly top 5% hotspot grid cells, whereas driest month (BIO14) for both 10% 20%. Prediction analysis demonstrated would particularly high invasion risk under current future scenarios. Regions increases species are more common (44.83–64.97%) than those decreases, except Representative Concentration Pathway (RCP) 4.5 scenario. Climate change will contribute greatly expansion optimistic (RCP 2.5) pessimistic scenarios 8.5). this study provide insights into priority management by developing promising strategies control prevention invasion.

Introduction risk of fire ants through container cargo in ports: Data integration approach considering a logistic network

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(2), P. e0313849 - e0313849

Published: Feb. 7, 2025

Invasive alien species introduced to ports through cargo containers have destroyed the biodiversity worldwide. The introduction risk at must be estimated control early stages of invasion. However, limited data are available for this estimation in stage. Spatial statistical models been used address lack information by considering observations neighbors or integrating multiple sources based on assumption spatial correlation. Unlike natural dispersal, methods these issues not yet established, because correlation between geographical distance is assumed human-mediated container cargo. Herein, we propose a multivariate conditional autoregressive model that considers logistic network order integrate and estimate risk. A relationship locations logistics connectivity rather than past. Hierarchical Bayesian were implemented two fire ant (Solenopsis invicta Solenopsis geminata) observed Japanese ports. We proposed joint improved fit compared conventional from single dataset. This finding suggests types helps observations. one first studies demonstrate effectiveness biological invasion networks contributes development reliable biosecurity strategies.

A mechanistic statistical approach to infer invasion characteristics of human‐dispersed species with complex life cycle

Ecological Monographs, Journal Year: 2025, Volume and Issue: 95(1)

Abstract The rising introduction of invasive species through trade networks threatens biodiversity and ecosystem services. Yet, we have a limited understanding how transportation determine spatiotemporal patterns range expansion. This knowledge gap may stem from two reasons. First, current analytical models fail to integrate the invader's life‐history dynamics with heterogeneity in human‐mediated dispersal patterns. Second, classical statistical methods often provide reliable estimates model parameters, such as time place characteristics, due spatial biases presence‐only records lack informative demographic data. To address these gaps, first formulate an age‐structured metapopulation that uses probability matrix emulate reveals invader spreads radially along shortest network path, inter‐patch distances decrease increasing traffic volume reproductive value hitchhikers. Next, propose hierarchical Bayesian method estimate parameters using data prior knowledge. show utility approach, analyze zebra mussel ( Dreissena polymorpha ) expansion North America inland commercial shipping network. Our analysis suggests mussels might been introduced before 1981, indicating lag 5 years between detection late 1986. Furthermore, our model, estimated one three chance they were near Kingsville (Ontario, Canada), where reported. We also find survival, fecundity, during early life (1–2 years) play critical role determining success mollusks. These results underscore importance fusing scientific observation processes framework for conceptual practical spread by human agency.

The global introduction of human-mediated trade and local dispersal through transport or natural pathways are major processes contributors to biological invasion. To effectively prevent manage invasion, invasions need be considered as a continuum (CGLD).
