Long distance dispersal with kinship in the Yangtze River during early life stage of a freshwater fish
October 2025
Aggregation is suggested beneficial with foraging, defense, and other fitness for the group members. While long distance dispersal with kinship has been found in several marine fishes, similar cases...
Mitigating methane emissions during nitrogen removal in constructed wetlands
October 2025
As nitrogen removal requires anaerobic conditions for denitrification, which facilitates the production of methane (CH4), a potent greenhouse gas, it is a challenge to achieve nitrogen removal with...
Exposure to chemical and commercial forms of NSAIDs at environmentally relevant concentrations exert transgenerational metabolic responses in daphnids
October 2025
Pharmaceuticals, including non-steroidal anti-inflammatory drugs (NSAIDs), such as indomethacin and ibuprofen, are prevalent pollutants in freshwater ecosystems, raising concerns about their ecological...
Family evolution and functional divergence of bony fish-specific Gig1 homologs
October 2025
Grass carp reovirus (GCRV)-induced gene 1 (Gig1) is identified initially in crucian carp C. auratus as a novel interferon-stimulated gene (ISG) encoding an antiviral protein and subsequently as the...
A new predictive model (MINASPACS) for spatially extensive biological assessments of southeastern Brazilian streams
October 2025
Freshwater ecosystems are threatened by flow regulation, sedimentation, habitat degradation, non-native species, and water pollution. These disturbances have led to global losses of biodiversity and...
Biologging as a potential platform for resolving ocean environmental issues and threats: Towards the development of the Internet of Animals
October 2025
Biologging is a method that utilizes animal-borne devices to study the behavioural ecology, physiology, and surrounding environment of animals. This is the Lagrangian observation method, which assigns...
Glacial microbial-environmental interactions on the Tibetan Plateau: A review
October 2025
The glaciers on the Tibetan Plateau are important climate regulators and recharge sources for many rivers and lakes, which are of great ecological value. However, actions to protect glacier-associated...
Mechanism of low temperature-induced intestinal damage in Danio rerio and the mitigating effect of alanylglutamine
October 2025
Recent cold waves and abrupt seasonal temperature drops have significantly impacted aquaculture, slowing fish growth and causing mass mortality. The intestine plays a crucial role in digestion, nutrient...
Land use extent and intensity affect the trophic structure of apex fish in neotropical lagoons
October 2025
The conversion of natural ecosystems to human land use is a primary cause of worldwide biodiversity loss and trophic structure changes in ecosystems. We investigated the effect of human land use at...
Non-native aquatic species in the Dongting Lake basin, China
October 2025
Dongting Lake is the second largest freshwater lake in China, supports high biodiversity and many endemic or endangered species, such as finless porpoise (Neophocaena phocaenoides), Baer's pochard (Aythya...
Atg9a is a critical factor in the immune response of grouper (Epinephelus coioides) to viral infection
October 2025
Autophagosome generation, development and maturation are largely dependent on Atg9a, an important member of the autophagy-related protein family. However, the potential role of fish Atg9a in viral infections...
Synthesis and properties of pentabutyryl glucose ester and its effects on the growth, liver and intestinal health, and gut microbiota of zebrafish (Danio rerio)
October 2025
Butyric acid and its derivatives are widely applied in aquaculture as an alternative to antibiotics, which are beneficial for the growth and health of aquatic animals. However, these products have some...
From primary to secondary invasions: Strategies to mitigate the invasion risk of pikeperch
October 2025
Aquaculture, as a major source of protein in the food industry, heavily relies on the introduction and farming of non-native species. Pikeperch, Sander lucioperca, an important fish in aquaculture,...
