Summary: Functional homogenization refers to the simplification of functional communities or species traits over time. Only a few articles have quantitatively evaluated functional homogenization in aquatic ecosystems. While functional homogenization is expected in most studies, the result depends on factors such as temporal and spatial scales and biological groups.

Summary: This study examines the impact of biodiversity on the nutritional value of seafood diets and human health. It reveals that species with different ecological traits in seafood have distinct micronutrient profiles, but increasing species richness does not necessarily increase protein content and may lead to higher concentrations of toxic metal contaminants. By drawing on biodiversity-ecosystem functioning theory, the study demonstrates the importance of biodiversity in enhancing nutritional benefits derived from seafood and consolidating sustainability goals for biodiversity and human well-being.

Summary: Organic farming is considered as the main alternative to reduce the environmental impact of intensive agriculture by banning synthetic inputs and enhancing ecological functions like biological pest control. However, the potential effects of farming management on natural enemy communities, pest control, and crop performance have not been well investigated. This study compared conventional and organic rice farming in terms of diversity and abundance of aquatic macroinvertebrate predators, pest infestation levels, biological pest control efficiency, and rice seed germination.

Summary: Biological control by natural enemies, specifically predators, in crop fields is influenced by both local management practices (such as organic manure or inorganic mineral fertilization) and the composition of predator communities in the surrounding landscape. The study found that organic fertilization coupled with predator spillover had a synergistic effect on suppressing aphid growth, highlighting the importance of promoting both local and mobile predators for effective biological insect pest suppression in agricultural ecosystems.

Summary: The influence of aquatic resource-inputs on terrestrial communities, particularly in the tropics, is not well understood. Stable isotope analysis revealed that riparian predators in tropical forests consume more aquatic prey and exhibit greater trophic diversity compared to those in temperate regions. This suggests that tropical riparian communities rely more heavily on and are more affected by aquatic resources, making them more vulnerable to disruptions in aquatic-terrestrial linkages.

Summary: Regional-scale ecological processes in river networks are fundamental for biodiversity and ecosystem functioning, but are often overlooked in river management practices. A meta-system approach is proposed to integrate these processes into river conservation, restoration, and biomonitoring, with the implementation of relevant measurements and indicators. Alternative management strategies are needed to guide practitioners in applying recent advances in ecology to preserve and restore river ecosystems in the face of increasing alteration of river network connectivity worldwide.

Summary: Mine pit lakes are flooded open-cut pits that occur worldwide. The remediation and closure of these lakes are crucial for sustainable development and freshwater ecosystem services. Pit lakes are known for their poor water quality and risks to communities and the environment, but planning for future uses can lead to better outcomes. Poor water quality does not necessarily limit future uses, and short-term uses should transition to long-term uses that promote biodiversity and adhere to safety and sustainability principles. Eventually, pit lakes can develop ecosystem values and be valued by future generations.

Summary: Understanding the interactive effects of multiple environmental stressors on energy flux in aquatic ecosystems is crucial for effective ecosystem management. This study found that the combined effects of climate warming, heat waves, nutrient enrichment, and herbicide exposure altered the pattern of energy fluxes within the food web. The effects of these stressors were primarily antagonistic or additive, presenting significant challenges for ecosystem restoration.

Summary: Sharks, including blue sharks, exhibit exaggerated physiological responses to capture and handling stress. The study found that blue sharks in recreational fishing can withstand capture and handling in a catch-and-release setting without experiencing blood acidosis. However, smaller individuals may be more susceptible to capture stress. The findings have implications for angler education in the recreational fishery.

Summary: Dehooking tools and bare hands were compared for their efficacy in removing hooks from Bluegill fish caught with barbed and barbless hooks. Bare hands took the longest time, while there was little difference in dehooking times among the tools used. However, using tools resulted in more tissue tearing compared to bare hands. Barbed hooks took significantly longer to remove than barbless hooks, and there was an increase in tissue tear size for fish caught on barbed hooks. Larger fish took longer to dehook, but tearing was not size-dependent. Bleeding incidence was low and not significantly different among treatments. Reflex impairment was observed only in fish caught on barbed hooks with longer dehooking times. Overall, using barbless hooks is more important than the specific dehooking tool used.

Summary: This study investigated the potential effects of red tide events on Atlantic tarpon along the southwestern coast of Florida. The results showed that tarpon are somewhat tolerant to red tide blooms, but when the blooms overlap with tarpon peak abundance and become dense and large, tarpon may leave the affected area or suffer mortality. Additionally, the study found an increase in the overlap of red tide blooms with tarpon spawning season. Combining multiple data sources helped elucidate how red tide exposure influences tarpon and the recreational fishery that targets them.

Summary: Fisheries are complex systems that face challenges from resource management to climate change. Transdisciplinary fisheries research (TFR) integrates different perspectives and knowledge systems, but there are limitations in capacity. Early career researchers' perspectives provide insights into challenges and potential for systemic change. This paper presents the perspectives of ECRs on TFR goals, challenges, and potential. Barriers include institutional inertia, lack of recognition for extra time and labor, and limited skill development opportunities. Actions for ECRs, established researchers, and institutions are identified to reach goals and overcome barriers.

Summary: The spatial ecology of common carp within Lake Ontario was studied using passive acoustic telemetry across multiple spatial scales. The study found that season and physical habitat conditions significantly affected the habitat preference of common carp, with higher preference for sites with increased submerged aquatic vegetation during spring and summer. Larger individuals were more likely to be absent from the array during summer. Non-resident common carp exhibited extensive movements along the nearshore of Lake Ontario during spring and summer and were detected throughout the entire basin.

Summary: The common carp is a non-native fish species that negatively impacts freshwater environments. Conventional management focuses on using barriers to control or contain the carp, but the impacts on native species should also be considered. Different biological traits, such as phenology, sensory ability, morphology, and behavior, can be exploited to design barriers that minimize the ecological impacts on native species.

Summary: Fishways can restore functional connectivity within rivers for migratory fish, but their success can vary. A study on the passage success of Chinook salmon in the upper Yukon River found that it was low overall, particularly for female salmon. In contrast, salmon migrating in a nearby free-flowing river had high migration success. The findings suggest opportunities for improving fishway performance and connectivity for this impressive animal migration.

Summary: During spawning migrations, adult Pacific salmon must undergo changes in gene expression and behavior to adapt to stressful conditions. Assessments of physiology and infectious agent presence in gill tissue can provide insights into these adaptations. The study found that migrating salmon exhibited decreased thermal stress gene expression and showed evidence of cooler water selection, suggesting behavioral changes and potential benefits of thermal refuges in reducing the negative impacts of infection.

Summary: Atlantic tarpon (Megalops atlanticus) supports an economically important fishery, but there is limited information on their fishery and population. A survey of anglers and fishing guides was conducted to address data deficiencies and understand the status and threats to Atlantic tarpon. The survey revealed a decline in fishing quality since the 1970s, with water and habitat quality as major threats. These findings highlight the importance of ecological knowledge from recreational anglers and fishing guides for the conservation of Atlantic tarpon populations.

Summary: The study found that temporarily retaining fish on stringers can increase stress and injury levels, leading to post-release mortality. Anglers and fisheries managers should consider restricting the release of fish placed on stringers, and treat fish on stringers as part of the angler's daily harvest limit.
