Summary: Since the early 1990s, the global spread of the invasive round goby has triggered extensive research worldwide. However, there is still a lack of a common theory explaining the invasion success, especially in round goby. To better understand and manage aquatic invasions, it is proposed to strengthen the network of goby researchers and establish long-term databases based on continuous and harmonized monitoring.

Summary: Early detection of the spatial expansion pattern of alien plants and the associated environmental factors is crucial for their management. Regression kriging and geographically weighted regression were used in this study to estimate the critical environmental factors related to the invasion of Hypochaeris radicata into new habitats. The results indicate that human activities and roads are the primary factors driving the expansion of H. radicata, while forest areas have not been invaded.

Summary: In Suriname, the use of mercury has increased due to gold mining, putting fish-reliant communities, such as Indigenous and Tribal communities, at risk of higher mercury exposure. However, the study found no significant increase in fish mercury levels over time or based on proximity to gold mining sites. Instead, remote unmined sites were found to be more susceptible to gaseous elemental mercury deposition, leading to increased contamination risk. This highlights the potential impact of mercury releases from gold mining on fish-reliant communities far away from the mining sites.

Summary: The impacts of omnivorous invaders on community structure and biomass of multiple trophic levels are complex and poorly understood. This study examined the differences in species diversity and ecosystem attributes between invaded and uninvaded reservoirs with populations of omnivorous zebra mussels at the southern invasion front in North America. The results showed greater differences in local ecosystem variables than community properties, with reductions in zooplankton and phytoplankton biomass, increases in water column transparency, and decreases in total phosphorus observed in invaded reservoirs.

Summary: The study found that fish reproductive activity occurred both upstream of the Jirau Dam and within the Santo Antonio Reservoir. Some ichthyoplankton crossed the Santo Antonio Dam downstream, but at least some of their larval development stages disappeared along the reservoir. A critical section was identified in the last 10 km of the reservoir, possibly due to the drifting characteristics or mortality rates.

Summary: In freshwater ecosystems, flood pulses, connectivity between environments, and vegetation mosaic are the main variables affecting environmental structure. Local limnological conditions are more important for structuring river fish assemblages. However, these limnological characteristics can have combined impacts on the environment. This study evaluates the main drivers of fish trophic guilds in lakes and determines the importance of limnological conditions, spatial distance, and riparian vegetation. Limnological variables and riparian vegetation influenced the distribution of trophic guilds, especially during low water periods.

Summary: This study examines the impacts of dam construction on fish assemblages in tropical freshwater ecosystems. Rarely available data obtained before and after damming were used to assess the effects. The results showed negative trends in most response variables, with temporal and spatial variation playing a larger role in explaining the variation. Therefore, preserving upstream tributaries and natural environmental variation may help mitigate the impacts of damming on tropical ecosystems.

Summary: This study assessed the invasion process of non-native fish species in the upper Parana River floodplain from 1986 to 2018. It aimed to answer three questions: (1) whether non-native species abundance differs between lakes and rivers; (2) whether the probability of occurrence of non-native species differs between lakes and rivers over time, and (3) whether the probability of occurrence is explained by functional traits, phylogenetic relationships, or native range. The analysis showed that species abundance was higher in lakes, while the probability of occurrence was higher in rivers. Range size, functional traits, and habitat use dimensions positively influenced the probability of occurrence of non-native species. The most important functional traits included offspring investment, egg size and fertilization type, defense, and shape factor.

Summary: Extreme climate events and damming of rivers can intensify the impacts of droughts and floods on aquatic biota. This study investigates how a prolonged drought affects the similarity of aquatic metacommunities compared to a period with extreme flood events. The results suggest that while environmental variability decreases during drought, the homogenization of biota depends on the component of beta diversity considered. The findings highlight the importance of natural flood events for maintaining environmental variability and ecosystem functioning in floodplains.

Summary: The introduction of non-native species and resulting biological invasions are prominent features of the Anthropocene Epoch. Some initiatives have emphasized the value and protection of invasive populations, but in the context of megadiverse tropical countries, the protection of highly invasive fishes, such as the peacock basses in Brazil, has raised concerns. Legal instruments have been proposed to restrict fishing and other activities to favor the recruitment, growth, colonization, and spread of these invasive species, but they pose significant risks of environmental degradation, biodiversity loss, and social conflicts.

Summary: This study evaluated the abundance of Salminus brasiliensis populations in the upper Parana River floodplain. Despite an overall decrease in abundance, less impacted sites had higher abundances and slower decline in probability of occurrence. These sites also showed improved fish condition over time. Protected areas in the upper Parana River played a mitigating role by slowing down population decline and serving as a source for propagation to other areas.
