Summary: Watersheds of the Great Lakes Basin in the USA and Canada have been significantly altered by human activities and pesticide use. Despite efforts to minimize risks to non-target organisms, there are concerns that pesticides are negatively impacting the environment. This study used toxicity estimates and high-throughput screening assays to identify pesticides and sites of concern in the streams of 16 tributaries. The results showed that pesticide levels exceeded benchmarks at multiple sites, with the highest impact observed in the Maumee River in Toledo, OH, USA. The study identified several pesticides of concern, including herbicides, fungicides, and insecticides.

Summary: Waterborne contaminants in 69 tributaries of the Laurentian Great Lakes were monitored using SPMDs and POCIS in 2010 and 2014. A risk-based screening approach was used to prioritize chemicals, identify sites at greatest risk, and determine potential hazards to monitor. Multiple chemicals were detected, with some showing toxicity quotients or exposure-activity ratios exceeding thresholds at various monitoring sites.

Summary: To assess the potential biological effects of pesticides in Great Lakes tributaries, a study monitored 223 pesticides and transformation products in 15 locations. The results showed that chemical concentrations were higher in watersheds draining agricultural and urban areas, and some chemicals exceeded levels of concern. The analysis also indicated potential activity on biological pathways related to cellular processes. This study provides important information for future monitoring and further evaluation of the effects of pesticides in the environment.

Summary: The study identifies omnipresent contaminants of emerging concern (CECs) in tributaries to the Great Lakes that pose potential hazards to aquatic species. Various approaches were used to predict vulnerability and hazards of CEC exposure to fish, with findings suggesting an overestimation of biological responses. Integrating these methods can assist in prioritizing management activities and research studies related to CEC exposure hazards for fish.

Summary: With improved analytical techniques, environmental monitoring studies are now able to report the occurrence of numerous chemicals per site, making it challenging to identify the most relevant ones from a biological perspective. This study examined the occurrence of organic chemicals, individually and as mixtures, and their potential biological effects. The results provide a screening-level prioritization of chemicals with the greatest potential for adverse biological effects and indicate the most likely sites where they occur.

Summary: Assessing the ecological risk of contaminants in the field is complex due to the mixture of compounds involved and the lack of data on the potential biological effects of many detected compounds. Advances in chemistry, toxicology, and bioinformatics have allowed for the development of concepts and tools to enhance the assessment of these contaminants. This article presents a multiagency effort to assess the occurrence and implications of contaminants of emerging concern (CECs) in the Great Lakes region, using state-of-the-science methods and models across multiple sites and species.

Summary: Contaminants of emerging concern (CECs) have been detected in urban surface waters within the Great Lakes. The study focuses on understanding the health consequences of environmentally-relevant exposures to CECs, especially as complex mixtures. The results show that compound mixtures become more complex downstream, indicating the dominance of wastewater effluent in the Lake Huron to Erie corridor and a mixed urban, suburban, and agricultural landscape in Lake St. Clair.

Summary: This study presents a taxonomic account and characterization of light micrographs of diatom taxa from the Laurentian Great lakes. A total of 154 taxa were identified, including both known and tentatively named or assigned ones. Lake and habitat specificity, optima for phosphorus and chloride, and tolerance to anthropogenic stressors were described for 39 common taxa.

Summary: This study analyzes the terrestrial water budget of the North American Great Lakes region using the Noah-MP land surface model. It shows that there are significant spatiotemporal differences in the hydrological budget, with precipitation and soil moisture explaining most of the variability in the southern basins, while the northern latitudes are snow-dominated regimes. The study also emphasizes that the variability in the terrestrial water cycle is crucial for assessing the impacts of climate and land cover changes in the diverse hydroclimate of the Great Lakes region.

Summary: The study found that mercury concentrations in the Laurentian Great Lakes are relatively low, but game fish concentrations are close to consumption advisory limits, indicating efficient methylmercury transfer from water to game fish. The bioaccumulation factors of mercury in phytoplankton are among the highest reported in water ecosystems and are influenced by dissolved organic carbon.

Summary: Climate refugia are special areas that provide protection for unique flora and fauna against prevailing climatic conditions. Physiographic features like large water bodies in the Great Lakes region create refugia favorable for fruit-bearing trees. However, global climate change may undermine the effectiveness of these refugia, leading to a decrease in fruit production.

Summary: The Laurentian Great Lakes are important and iconic ecosystems facing the problem of microplastic pollution, among other anthropogenic stressors. This study provides a comprehensive probabilistic risk assessment for these lakes, addressing the uncertainties and misalignments in the exposure and effect data for microplastics. The results show that although there is no lake-wide risk, there is a probability of risk from food dilution in certain parts of the lakes.

Summary: The study found that the passive adhesive performance of climbing gobies is influenced by species and substrate, with the strongest climbers exhibiting the highest shear pull-off forces on rough surfaces. Therefore, differences in adhesive performance may help explain the ability of species to migrate upstream and invade new habitats.

Summary: Long-term monitoring has shown that despite reductions in mercury emissions in the United States and Canada since 1990, contamination in fish from remote lakes and rivers still exists. However, the study suggests that regional to continental-scale decreases in mercury and sulfate emissions have benefitted aquatic resources.

Summary: Evolution of locomotor modes in goby fish is associated with morphological adaptations to meet the demands of various environments, such as marine and freshwater habitats. Climbing gobies have unique vertebral column structures that aid in vertical thrust production, with flexibility in the posterior portion of the body and larger intervertebral spaces in species that exhibit distinctive climbing behaviors.

Summary: Freshwater streams on oceanic islands are important for ecological and economic functions, but are often overlooked in assessments of pollution. This study found that Hawaiian streams are contaminated with various pollutants, comparable to continental streams, and have subtle effects on native fish species' locomotor performance. These results highlight the importance of including endemic species and ecologically relevant assays when assessing the effects of contaminants in island habitats.

Summary: Accurately measuring chemical exposures and biological effects in surface waters is a major challenge in ecotoxicology. This study used the transcriptome of Daphnia magna to detect distinct responses across different water sources in Minnesota. The results showed that each water source had a unique gene expression profile, with the most significant factors influencing gene expression patterns being pyriproxyfen exposure, season of stormwater sample collection, and wetland quality.

Summary: The functional capacities of animals are crucial for their survival and reproduction in nature. Understanding the biomechanical performance of animals can provide insights into various aspects of their biology, including ecological distributions and evolutionary diversification. By studying the comparative biomechanics of amphidromous goby fishes, we have clarified how different aspects of biomechanical performance contribute to their ecological and evolutionary diversity. Our research highlights the importance of integrating knowledge of mechanical underpinnings to gain critical insights into ecological and evolutionary questions.
