Summary: Studies have shown that the colonization of excavations and sedimentation tanks in opencast mines is influenced by substratum, land relief, hydrological and hydrochemical relations. Invasive species such as black locust tend to colonize sandy habitats successfully due to a lack of trees and dense grasses, and their role increases along a gradient of dryness and vegetation development.

Summary: Bioplastics are considered as safer alternatives to address the persistence of conventional plastics, however, little is known about the release of additives and NIAS in the environment and the biological effects of their leachates. In this study, leachates from different bioplastics and a control material were examined and it was found that NIAS were the main components in bioplastics. Bisphenol A and trace metals were detected in all leachates, and biological effects were observed in early embryo stages of Mytilus galloprovincialis. Adult mussel physiology was also affected after exposure to the leachates. Harmonized chemical and biological approaches are recommended to assess the safety of bioplastics.

Summary: Inoculum size and heat perturbations have synergistic effects on predicting the invasion success of soil pathogens. Heating increases soil resource availability, but reduces resource differentiation between the pathogen and indigenous bacteria. The abundance of the pathogen increases with inoculum size in both heated and non-heated soils, with a greater effect in heated soils. Inoculum size and the increase in available carbon and nitrogen in the soil best predict invasion success.

Summary: The relationship between number of introduced individuals and introduction success is positively correlated, but successful establishment can still occur with smaller-than-expected founding populations, indicating the importance of chance in species introductions. A simulation model was used to evaluate the likelihood of success for the introduction of island canaries to Midway Atoll, with juvenile mortality rates found to have a significant impact on introduction success. Factors such as behavioral plasticity in mate selection, resistance to inbreeding depression, and reduction in juvenile mortality rates via human assistance were identified as potential contributors to increased likelihood of success in small introductions.

Summary: This study models the risk differences in cargo vessel discharges that meet the IMO D-2 standards and analyzes the impact on invasion risk. The results indicate that community composition strongly affects the risk, and colonization pressure has a significant influence at low community propagule pressure. The IMO D-2 standards require very low individual propagule pressures and community propagule pressures, and more empirical research is needed to determine if vessels can meet these requirements.

Summary: This study provides an updated list of mammalian species with established wild populations in the Neotropics and compares genetic variability between native and introduced populations. Loss of genetic variability is common in introduced populations, suggesting they have successfully established in new environments, supporting the genetic paradox of invasions. However, the magnitude of loss is not related to the number of introduction events or individuals, indicating a need for alternative approaches to estimate genetic diversity.

Summary: Geographical variation in the likelihood of biological invasions is influenced by propagule pressure and habitat suitability driven by ecological and social processes. By using eradication programs as proxies for new establishment events, it was found that socio-environmental factors such as human population size, climate, and availability of host trees significantly affect the probability of L. dispar arrival and establishment.

Summary: Behavioral parameters are sensitive and early bioindicators of toxicity in aquatic organisms. A video-tracking tool was used to monitor the swimming behavior of Mediterranean mussel larvae and investigate the effects of copper, silver, and temperature on their behavior and acetylcholinesterase (AChE) activity. The results showed that the exposure to copper and/or silver and the increase in temperature disrupted the swimming behavior of the mussel larvae, and AChE activity was positively correlated with maximum speeds. This study highlights the importance of behavioral analysis in assessing the effects of stressors.

Summary: Recent studies have shown that spatial synchrony is correlated with species specialization and growth rate, but the study in the Cana Brava Reservoir did not find a significant relationship between synchrony and these factors. Future studies should focus on a common set of explanatory variables to assess the generality of correlates of spatial synchrony.

Summary: Water-level oscillations play a significant role in shaping the community structure and diversity of chironomid larvae in tropical lakes. Environmental factors have a greater impact on chironomid composition during low-water-level periods compared to high-water-level periods. Extreme low- and high-water-level periods in floodplain systems may become more frequent and intense in the future, affecting the richness, density, and temporal beta-diversity of chironomids.

Summary: This study investigated the distribution of L. fortunei larval stages in floodplain environments and identified local abiotic filters that affect the density of each larval stage. The results showed that L. fortunei population pyramid is expanding in these environments, with the youngest larval stages accounting for the majority of the density. Abiotic factors such as turbidity, water level, and suspended inorganic matter directly decreased the density of the youngest larval stages, while temperature and pH directly increased the density of older larval stages. Water level indirectly affected the density of the youngest larval stages through its effects on turbidity and suspended inorganic matter.

Summary: Invasive species show greater resilience to drought but are more negatively affected by interspecific competition compared to native species. The high dominance of invasive species in aquatic ecosystems can be explained by their ability to recover from drought disturbances, while the presence of native species acts as a biotic resistance mechanism.

Summary: This study examines the effects of nutrient loading on shallow lakes, and how regime shifts from clear water to turbid or shaded states affect biodiversity and ecosystem functioning. The results show that functional diversity is the best predictor of ecosystem multifunctionality, and that regime shifts towards turbid or shaded states negatively impact taxonomic diversity and functional diversity of fish and zooplankton, leading to decreased multifunctionality.

Summary: This study estimates the rate of increase and doubling times of new records of 178 invasive alien species (IAS) using a global dataset. It finds that the number of IAS records has exponentially increased with a mean doubling time of around 14 years across the Earth. The records of IAS increased faster in non-native continents, suggesting an exponential expansion of their range size. Each continent has a taxonomic group with a particular increase in IAS records. The study highlights the need for more effective global efforts to control invasions.

Summary: Many studies have shown that biodiversity plays a crucial role in maintaining the productivity and functionality of ecosystems. In this study, the researchers investigated the association between species richness, functional diversity, and ecosystem multifunctionality in 72 lakes across four wetlands in Brazil. They found that higher species richness and functional diversity were positively correlated with ecosystem multifunctionality. However, human activities negatively impacted the diversity of aquatic organisms, leading to a decrease in wetland multifunctionality.
