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: 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: 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: Efforts to restore river ecosystem connectivity mainly focus on diadromous fish species, while less attention is given to nonmigratory benthic fish species. Comparative swimming performance and behavior experiments were conducted on the invasive round goby and two native species. Results showed high variation in swimming performance and behavior among the three species, with the gudgeon displaying the best swimming performance.

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: 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.

Summary: Research indicates that the global economic cost of aquatic invasive alien species has reached $345 billion, with the majority attributed to invertebrates, vertebrates, and plants. The highest costs were reported in North America and Asia, primarily due to resource damages. The costs of aquatic invasive species have increased exponentially in recent decades, but are likely underreported.

Summary: This study found that boldness in Neogobius melanostomus can impact foraging competition, with bold individuals consuming fewer prey compared to shy individuals. However, competition is not solely dependent on personality, as other mechanisms also play a role.

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: This study investigated the expression response of the hsp70 gene in the invasive round goby to different salinity levels, showing highest stress in fresh water and lower stress in brackish and oceanic salinities. The results have implications to predictions for the species' plasticity potential and possible range expansion into other salinity regimes.

Summary: The invasive round goby utilizes vertical harbor walls as habitat and exhibits differences in trophic niche and breeding frequency compared to bottom-dwelling individuals. This ability to use anthropogenic structures and the presence of competitive individuals contribute to the invasion success of round gobies.

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 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: 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.
