AI Article Synopsis

  • Researchers measured the levels of omega-3 fatty acids (EPA and DHA) in Eurasian perch from various types of water bodies.
  • They created a formula to estimate the amount of these beneficial fats based on the phosphorus levels in the water.
  • The study concluded that the highest omega-3 content is found in fish from mesotrophic waters, making this an ideal source for human consumption.

Article Abstract

For the first time, the quantity of protectors of cardiovascular deceases-omega-3 polyunsaturated fatty acids, eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic (22:6n-3, DHA), obtained through fish (Eurasian perch) catch in water bodies of different trophic status was determined. A formula was drawn to calculate the quantity of obtained EPA + DHA (kg km year) depending on the concentration of total phosphorus in water. It is found that the maximum quantity of EPA + DHA can be obtained by humans from fish caught in mesotrophic water bodies.

Microplastics (MPs), as the crucial environmental pollutants, can be easily transported into the human body and accumulate in the liver. However, current studies mainly focus on acute exposure to MPs, investigations on long-term interactions with MPs alone remain limited. Thereby, we examined noxious properties of MPs and selected the most common polystyrene (PS) MPs as the research object, including unmodified PS MPs (PS-MPs) and positive-charged PS MPs (PS-NH) at 10 mg/L employing oral drinking water methods in mice for six consecutive months in vivo.

In developing tissues, the number, position, and differentiation of cells must be coordinately controlled to ensure the emergence of physiological function. The epidermis of the Xenopus embryo contains thousands of uniformly distributed multiciliated cells (MCCs), which grow hundreds of coordinately polarized cilia that beat vigorously to generate superficial water flow. Using this model, we uncovered a dual role for the conserved centriolar component Odf2, in MCC apical organization at the cell level, and in MCC spatial distribution at the tissue level.

Nitrogen and phosphorus inputs to surface water bodies lead to a decline in water quality and a disruption in the balance of aquatic ecosystems. Emergent aquatic plants were widely used for their high efficiency in removing nitrogen and phosphorus from surface waters. However, there was a lack of systematic analyses on the purification of surface waters by emergent aquatic plants, and the mechanism of differences in nitrogen and phosphorus removal by different plants needs to be further revealed.

This study addresses the significant issue of rapid land use and land cover (LULC) changes in Lahore District, which is critical for supporting ecological management and sustainable land-use planning. Understanding these changes is crucial for mitigating adverse environmental impacts and promoting sustainable development. The main goal is to evaluate historical LULC changes from 1994 to 2024 and forecast future trends for 2034 and 2044 utilizing the CA-Markov hybrid model combined with GIS methodologies.

Artificial fish nests are common tools in fisheries management, providing spawning grounds to enhance the size and diversity of fish populations. This study aimed to explore the effects of deployment locations on the reproductive efficiency and preferences of fish with adhesive and demersal eggs using artificial nests. Floating artificial nests were deployed in three regions (upstream, midstream, and downstream) of a reservoir in Zhejiang, China, at locations with three topographical types: steep slope (reservoir shore, slopes > 60°), gentle slope (reservoir shore, slopes < 30°), and confluence (middle thread of channel).
