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: The study found that the round goby is more aggressive and dominant towards the marbled crayfish, but their predation on juvenile crayfish is limited by mouth gape size. In pairs of similar weight, gobies are more aggressive, although both species affect each other's behavior.

Summary: This study investigated the differences in nonmating behaviors between sneaker and guarder males in the round goby species, finding that sneaker males were more active, explorative, bold, and behaviorally plastic compared to guarder males. This research helps expand our understanding of the variations in alternative reproductive tactics, particularly in nonmating contexts.

Summary: The round goby, an invasive species, has been observed in both the Baltic Sea and the North American Great Lakes, causing negative impacts on specific molluscan taxa. While some groups are affected, others appear to be largely unaffected or even show positive trends following the invasion.

Summary: Neogobius melanostomus, an invasive fish species, poses a potential threat to crayfish and A. aquaticus populations in river tributaries, potentially causing disruptions to the macrozoobenthic community and triggering trophic cascades. Its non-selective feeding behavior may have significant ecological impacts on the ecosystem.

Summary: Freshwater mussels are crucial to riverine ecosystems, but their decline worldwide has raised concerns for conservation. This study reveals the invasive Round Goby's propensity to prey upon indigenous freshwater mussels, posing a growing threat to both common and endangered species. The introduction of Round Goby to North American freshwaters has significant implications for conservation and management.

Summary: In this study, the population development of round goby in Latvian coastal waters was characterized using data from scientific surveys and commercial fisheries landings. The results showed an exponential increase in population numbers, peaking in 2018 and then sharply declining. Intensive commercial fishing was identified as a significant factor in the decline, and similar declines were observed in other areas of the Baltic Sea. The study contributes to the understanding of invasive fish populations and provides recommendations for future monitoring efforts.

Summary: The study supports the predictions of the Antarctic climate-diversity-invasion hypothesis, indicating that climate change affects the abundance and diversity of indigenous fauna in the Antarctic region. Invasive alien species have negative impacts on indigenous fauna. The research shows that the density of indigenous fauna on invaded islands in the Antarctic is significantly lower than on uninvaded islands.

Summary: This study investigated the effects of salinity on oxygen consumption and behavior in the invasive round goby and the native European perch. The results showed that the invasive round goby is more sensitive to salinity changes, while the native European perch is less affected. This finding suggests that invasive species may be less tolerant to environmental changes and highlights the species-specific nature of salinity effects.

Summary: Identifying new areas of colonization by alien species is crucial for early detection and management. This study used habitat suitability modeling to identify the most likely areas for introduction and first establishment of the invasive round goby in Norway. Despite the lack of presence-absence data, the study was able to provide valuable insights using spatial analyses and knowledge of dispersal pathways and the species' biology. The results highlight several potential areas and hotspots for future invasion, particularly in less-exposed coastal brackish areas of southern Norway.

Summary: This field study revealed that the non-native round goby has negative impacts on the diversity of native epifaunal macroinvertebrate communities in the Baltic Sea, decreasing overall abundance, biomass, and taxon richness while altering trait-based composition. The predation of round gobies on larger epifaunal individuals led to an overall decrease in invertebrate body size, potentially affecting ecosystem processes and functioning in invaded areas.

Summary: The secondary invasion of the round goby into tributaries of the Laurentian Great Lakes has resulted in ecological impacts on many native benthic species. This study examined the dietary impact of the round goby invasion on white sucker and found significant diet overlap between the two species. White sucker in sympatry with round goby shifted their feeding strategy to be more generalist. However, no influence of diet competition with round goby on the trophic niche of white sucker was found.

Summary: Identifying general patterns and trends underlying the impacts and dynamics of biological invasions has proven elusive for scientists. Recently, the impact curve was proposed as a means to predict temporal impacts of invasive alien species, characterised by a sigmoidal growth pattern with an initial exponential increase, followed by a subsequent rate of decline and approaching a saturation level in the long-term where impact is maximised.

Summary: The study comprehensively evaluated invasion risk levels of Chinese provinces using multiple invasion indices and taxonomic groups, predicting distribution patterns based on environmental and anthropogenic factors. Results identified 17 provinces as high invasion risk regions, with environmental and anthropogenic factors showing similar prediction abilities on invasive species richness.

Summary: Invasive species, such as the round goby in this study, demonstrate a high level of thermal resilience across a broad temperature range as they maintain a large thermal safety margin through constant physiological performance. This thermal resilience, possibly facilitated by phenotypic buffering, allows invasive species to be highly adaptable and competitive in changing environments, potentially increasing their success under continued climate change.
