:This study represents the efforts of a network researchers to characterise large, floating Sargassum (Fucales, Phaeophyceae) biomass that had reached Brazilian coast in 2014 and 2015. Material collected during these events was identified as natans S. fluitans using morphological characteristics; ITS2 sequences showed low divergence (0%–3%) with nine other species. Several epiphytic macroalgae, invertebrates fishes were associated Sargassum. Satellite images did not support hypothesis slicks...
Abstract Rhodolith beds are important marine benthic ecosystems, representing oases of high biodiversity among sedimentary seabed environments. They found frequently and abundantly, acting as major carbonate 'factories' playing a key role in the biogeochemical cycling carbonates South Atlantic. Rhodoliths under threat due to global change (mainly related ocean acidification warming) local stressors, such fishing coastal run-off. Here, we review different aspects biology these organisms,...
Marine heatwaves (MHWs) are a major concern worldwide due to their increasing impacts in recent years, and these extreme events may trigger deoxygenation of coastal waters affected by sewage eutrophication. Here we investigate the combined effects MHWs nutrient enrichment on water quality biodiversity Bay Santa Catarina Island (Brazil). We used historical (1994–2020) sea surface temperature data from satellites situ physical, chemical biological parameters assess temporal trends. Oxygen...
Mycosporine-like amino acids (MAA) are ultraviolet screen substances synthesized by marine algae. The physiological function of these is related to cellular protection against UV radiation and as a protective mechanism oxidative stress. These can be found mainly in the ocean, among red seaweeds. Its concentration organisms has been availability inorganic nitrogen environment. We start our study MAA content different species understand if environmental conditions influence MAAs Brazilian...
The coal mining activity is characterized by the generation of large amount by-products. One them pyrite, which tends to acidify water, solubilizing heavy metals. As a consequence environment becomes acid and rich in metals, selecting microorganisms able survive this condition, are great interest as bioremediation agents. This work describes isolation characterization from area Santa Catarina. These comprised bacteria, fungi yeasts resistant zinc, nickel cadmium.
Anthropogenic impacts on water resources, especially by nutrient discharge, is a worldwide problem in marine coastal areas. In this context, seaweed cultivation aquaculture wastewater can be considered as an alternative for effluent mitigation, where the biomass becomes source of valuable compounds. The current study examined potential use seaweeds Ulva pseudorotundata and rigida to remove nutrients treat effluents from culture Chelon labrosus . Two experiments were conducted under...
The aim of this study was to understand how a stream ecosystem that flows from its fountainhead mouth inside city, changes water resource point pollution source. A multidisciplinary descriptive approach adopted, including the short-term temporal and spatial determination physical, chemical, biological ecotoxicological variables. Results showed quality rapidly decreases with increasing urbanization, leading system acquire raw sewage attributes even in first hundred meters after fountainheads....
