Plastic pollution and invasive species are recognised as pervasive threats to marine biodiversity. However, despite the extensive on-going research on microplastics' effects in biota, knowledge their combination with additional stressors is still limited. This study investigates of polyamide microplastics (PA-MPs, 1 mg/L), alone toxic exudate from red seaweed Asparagopsis armata (2%), after a 96 h exposure, mussel Mytilus galloprovincialis. Biochemical responses associated oxidative stress...
During the Spanish colonial era, ships frequently transported mercury across Atlantic to New World be used in gold mining. As many of those eventually sank, shipwrecks may represent a local source contamination marine environment. In this context, evaluating coastal sediments and magnification food webs is crucial for understanding dynamics estimating exposure life locations where occurred. This study investigated concentration present biota from three distinct groups: macroalgae...
Asparagopsis armata is classified as an invasive species in Europe. Through the exudation of secondary metabolites, this macroalga holds a chemical defence against consumers, with potential toxic effects to native rocky shore communities. This study aims evaluate impact A. (gametophyte) exudate species, mussel Mytilus galloprovincialis, terms biochemical and organismal effects. The 96 h-LC50 was 3.667% based on it, concentrations (0.25; 0.5; 1; 2%) were determined further sublethal...
In this study, we evaluated the bioaccumulation of mercury in zebrafish (Danio rerio) exposed to mercury-contaminated food for 21 days and depuration a subsequent post-exposure period 28 days. Four tissues (muscle, liver, gills, skin) were analyzed content. Overall, data indicated that Hg accumulation liver is faster than other tissues. Furthermore, tissue with highest rate per day (0.021 µg g−1 day−1), followed by muscle, skin, gills. Conversely, rates different showed following order:...
Microplastic pollution, global warming, and invasive species are known threats to marine biota, but the impact of their simultaneous exposure is still not well understood. This study investigated whether toxic effects posed by red seaweed Asparagopsis armata exudate (2%) mussel Mytilus galloprovincialis amplified a 96 h increased temperature (24 °C) polyethylene microplastics (PE-MPs, 1 mg/L). Biochemical (neurotoxicity, energy metabolism, oxidative stress, damage) physiological (byssal...
Abstract The veined squid, Loligo forbesii Steenstrup, 1856, occurs at the European Shelf areas including Azores and represents a valuable resource for commercial fishery in North East Atlantic. However, very little is known about its population structure phylogeography. This lack of knowledge also impedes development sustainable management this species. present study combined use two types markers that retrieve patterns gene flow different time spans; analysis 16 nuclear microsatellites...
Because both predation risk and resource quality have a pivotal role in ecological communities, their combined effects were assessed stream detritivores. Bioassays conducted using simplified trophic chain, coupling of basal resources with different nutritious qualities, namely, predator planarian Dugesia subtentaculata, caddisfly shredder Sericostoma vittatum, dipteran collector Chironomus riparius, native alder Alnus glutinosa invasive eucalypt Eucalyptus globulus. We investigated whether...
Ocean warming and biological invasions are among the most pervasive factors threatening coastal ecosystems with a potential to interact. Ongoing temperature rise may affect physiological cellular mechanisms in marine organisms. Moreover, non-indigenous species spread has been major challenge biodiversity ecosystem functions services. The invasive red seaweed
Due to global warming, in the northeastern semiarid coastal regions of Brazil, regional and drivers are responsible for decreasing continental runoff increasing estuarine water residence time, which promotes a greater mobilization bioavailable mercury (Hg) allows fluxes and/or bioavailability this toxic trace element an acceleration biogeochemical transformation Hg. In work, application dendrochemistry analysis (annular tree rings analysis) was developed reconstruction historical pattern...
The consumption of fish is usually considered the main route contamination mercury in humans. In a climate change scenario implying ocean acidification, methylation expected to increase leading bioaccumulation increments food chain, affecting mainly coastal populations.
