Ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico
A new study from World Data Ocean examines ecological patterns of trace and essential metal bioaccumulation in marine fish from the Gulf of California, Mexico. Researchers evaluated concentrations of eleven elements—including arsenic, selenium, and uranium—across three fish species from distinct feeding guilds at two locations, revealing significant variability linked to species ecology, regional geology, and historical mining activity. Notably, selenium exhibited high bioaccumulation, while arsenic concentrations displayed interspecific differences.
From nutrients to nutrition: nitrogen pathways and seafood nutritional quality in the Black Sea - a systematic review
The Black Sea's rich fisheries—particularly small pelagic fish and bivalves—are a vital source of protein, omega-3s, and essential micronutrients. However, ongoing environmental degradation raises concerns about the long-term nutritional value of this resource. A recent systematic review, adhering to PRISMA 2020 guidelines, reveals a critical knowledge gap: while broader nitrogen pathways are documented, direct biochemical measurements within key species like horse mackerel and anchovy remain limited.
Climate warming drives multidimensional reorganization of global zooplankton community structure and function: an updated review
Climate warming is fundamentally reshaping global zooplankton communities, impacting their structure and function through a complex interplay of environmental stressors—ocean warming, acidification, and intensified stratification, among others. This updated review synthesizes empirical evidence, highlighting how these drivers influence species distributions, body sizes, and ecosystem processes like carbon cycling and nutrient regeneration. Taxonomic and regional variability significantly affect these responses, demanding integrated approaches combining long-term observations and advanced modeling.
