Summary: In this study, cockles were found to exhibit different burrowing/emergence patterns in response to salinity variations: buried in sediment at high salinities, actively emerging as salinity decreased, and exposed at the sediment surface when salinity was <10. These behavioral changes may represent a survival strategy for this species in response to flooding events, as being at the sediment surface could enable transport towards more suitable areas.

Summary: The Andean Paramo, with its distinct vegetational zones, has a vast water storage and carbon fixation capacity. This study examines the activity of several enzymes at different altitudes and sampling depths, and finds a tendency towards decreasing enzyme activities at higher altitudes and in the dry season. The outcome suggests that slight environmental changes might lead to increased organic matter decomposition and endanger the paramo region and its ecosystem services.

Summary: Weaning is crucial for young ruminants, as it causes significant changes in rumen function, bacterial composition, and enzyme activity. Post-weaning calves showed a more complex rumen bacteria network, higher fermentation products, and microbial protein content, but lower digestive enzyme activity compared to pre-weaning calves. These findings highlight the importance of weaning on rumen function and provide valuable insights for calf feeding management.

Summary: The study aimed to investigate the activity and characteristics of digestive enzymes in juvenile greater amberjack and their modulation by water temperature. The results showed that chymotrypsin was the most active enzyme, while lipase had the lowest activity. Both enzymes, as well as trypsin, were responsive to water temperature. The study also revealed the importance of pH-sensitive and thermally robust proteases in greater amberjack. The findings contribute to the understanding of the species' digestive biochemistry and can help improve management practices in its industrialization.

Summary: Celtis australis, an important agroforestry tree species in the Himalayan region, plays a crucial role in sustaining the life of rural communities. The nutritive values of this species are influenced by altitude and harvesting season, showing significant seasonal and altitude variations. Potassium, calcium, crude protein, and starch content increase with altitude, while dry matter content, phosphorus, and soluble sugars decrease with altitude.

Summary: The study showed that protein levels increased during the transition from proliferation to maturation in gonadal tissue of C. hongkongensis, while maintaining a well-balanced essential amino acid profile meeting the requirements of preschool children. The lipid content and fatty acid composition varied with the reproductive cycle, but the omega-3:omega-6 ratio was consistently higher than in other bivalve species.

Summary: This study investigated the effects of Bacillus subtilis supplementation on the growth performance, organ weight, and serum biochemical indices of broiler chickens. The results showed that Bacillus subtilis could be used as an alternative to antibiotics, as it improved body weight gain, organ weight, serum metabolite concentrations, and digestive enzyme activities in broilers.

Summary: The study found that seawater acidification benefits the productivity of Ulva compressa by increasing photosynthetic pigments and primary metabolites levels. Acidified conditions also enhance mineral and polyunsaturated fatty acid content, while reducing malondialdehyde (MDA) levels, indicating a decrease in oxidative stress. However, total antioxidant capacity and various antioxidants were reduced in thalli grown under acidified conditions.

Summary: This study found that supplementation of oregano essential oils (OEO) can enhance rumen digestive ability in cattle by modulating epithelial development and microbiota composition. High dose of OEO led to longer rumen papillae, increased relative abundance of propionate and butyrate, and changes in enzyme concentrations.

Summary: Research found that there are close connections between the morphological, anatomical and biochemical traits of Sphagnum mosses, which are driven by their shared responses to local and regional environmental factors. The relationships between biochemicals and certain morphological traits can describe physiological dimensions that are not captured solely by anatomical and morphological traits alone. These findings are important for enhancing our understanding and predictive power in Sphagnum ecology.

Summary: The present study evaluated the effect of replacing fish meal with cricket meal on the growth performance of largemouth bass. The results showed that up to 45% of cricket meal can replace fish meal in the diet without significantly affecting the growth performance. However, when the replacement reached 60%, the fish exhibited lower weight and growth rate. The study also found some differences in serum biochemical indices and antioxidant capacity.

Summary: Increases in seawater temperature and reduction in light quality pose significant threats to marine coastal communities, including seagrass ecosystems. Seasonal acclimatization plays a critical role in modulating productivity and biochemical responses of Zostera marina to environmental stressors such as warming and irradiance reduction, with different results observed across seasons and temperatures.

Summary: The study examined the use of mannan oligosaccharides (MOS) as functional additives in grey mullet diets, showing significant improvements in growth performance, digestive enzyme activity, blood chemistry, and antioxidative capacity. MOS at 0.5-1% is required for enhancing the productivity of grey mullet.
