Summary: Plant invasions are increasing worldwide due to globalization. Efforts have been made to understand and predict the success of non-native plants, with various frameworks and theories proposed. This review focuses on terrestrial systems and explores the roles of plant properties, biotic and abiotic conditions, and human-induced changes in mediating invasion success.

Summary: This study compared and evaluated four different indices of biotic integrity using stream fish community data, and found that the relationships among the indices varied across different management jurisdictions. The indices showed different sensitivities to changes in community composition due to replacements of native with non-native species and year-to-year species turnover. Resampling through bootstrap analysis showed the potential to significantly change resulting scores and alter stream health designations. Therefore, the potential advantages and limitations of indices of biotic integrity should be considered when selecting and using them in a given region.

Summary: This paper discusses the impact and importance of global invasive alien plants in freshwater ecosystems, pointing out emerging trends. Invasive alien plants have significant effects on freshwater biodiversity and ecosystem function, and a comprehensive understanding of their potential impact is needed from an ecosystem perspective.

Summary: Rigorous assessments of water resources' ecological condition and the impact of human activities on them require quantitative data, showing that artificial disturbances have negative effects on physical habitats. The U.S. Environmental Protection Agency's study found that a certain proportion of rivers and lakes in the country are in poor condition, characterized by anthropogenic disturbances, sediment accumulation, inadequate riparian vegetation cover, and low habitat complexity. The severity of these conditions varies in different ecological regions.

Summary: This study assessed people's perceptions of invasive alien plants (IAPs) in the riparian zone of the Ganga River in Varanasi, India. The results showed that residents were aware of IAPs and perceived them both positively and negatively. Socio-demographic factors such as age and education influenced people's perceptions of IAPs. Fire was commonly used as a management practice for IAPs.

Summary: The study found that invasive earthworms have led to changes in plant communities in North American forests, but their impact on plant community biomass and cover is not significant. The functional trait responses of different plants to earthworm invasion are species-specific, with some traits showing opposite responses within the presence of earthworms.

Summary: Based on a study conducted on three rivers, it was found that the impact of the Eurasian beaver on the tree layer of Mediterranean riparian sites is still unclear. The beavers mainly gnaw on willows and poplars, and their activity is most concentrated within ten meters from the riverbank. This research can serve as a model to predict mid-term riparian forest vegetation changes in other Mediterranean sites where the beaver population is expanding.

Summary: Urban forests have an impact on land surface temperature (LST) in cities due to the cooling effect of transpiration. Research has shown a positive correlation between urban forest tree diversity and LST, as well as a negative correlation between biotic disturbance and LST, indicating that the health of urban forests is affected by both factors.

Summary: This study aims to develop a system for assessing and mapping forest ecosystem integrity and services. By quantifying reference states for 61 forest ecosystem types, testing the use of soil monitoring data, modeling chemical soil indicators, and verifying indicator modeling, the study advances methodology for evaluating ecosystem integrity.

Summary: This study identified cryptic tolerant species using a dataset of stream fish and land cover data, and compared two indices of stream health. The results indicated that the proportion of cryptic tolerant species decreased with an increasing proportion of forested land, while the proportion of true sensitive species increased. However, both indices had a low correlation with expected disturbance levels.

Summary: Both biotic interactions and abiotic processes play important roles in shaping riparian communities. This study conducted an experiment to investigate the effects of interspecific competition and sediment burial on the survival, growth, and reproduction strategies of an endangered pioneer herbaceous plant species. The results showed that sediment burial had a significant negative impact on the plant's traits, while interspecific competition had minimal effects. Future research should focus on other abiotic factors to better understand population trends in alpine areas.

Summary: Agricultural activities lead to decreased avifauna diversity and biotic homogenization, compromising ecosystem functioning and resilience. However, the impacts of agriculture on bird communities in arid ecosystems are understudied.

Summary: Studies show that both riparian and non-riparian chestnut forests may serve as habitats for the Spotted Wing Drosophila, and there is a positive correlation between the spatial proximity of forest patches to streams and SWD captures.

Summary: The number of alien plant species is increasing in riparian ecosystems worldwide, which has negative consequences for native species communities and ecosystem services provision. In Portugal, invasive alien plants are more abundant in low altitude areas and downstream regions with high human concentration. Future efforts should focus on coordinated national and local measures to prevent and manage biological invasions, aligned with the EU Biodiversity Strategy for 2030.

Summary: This study compared the functionality of low-metric and metric-rich coldwater FIBIs for estimating stream health and found that the metric-rich index had improved ability to differentiate lower quality sites. The presence of Brook Trout was indicative of coldwater stream health for both indices, suggesting its importance in stream health assessments.
