Microplastics are routinely ingested and inhaled by humans other organisms. Despite the frequency of plastic exposure, little is known about its health consequences. Of particular concern additives─chemical compounds that intentionally or unintentionally added to plastics improve functionality as residual components production. Additives often loosely bound polymer may be released during exposures. To better understand effects additives, we performed a comprehensive literature search compile...
Oxidases are found to play a growing role in providing functional chemistry marine adhesives for the permanent attachment of macrofouling organisms. Here, we demonstrate active peroxidase and lysyl oxidase enzymes adhesive layer adult Amphibalanus amphitrite barnacles through live staining, proteomic analysis, competitive enzyme assays on isolated cement. A novel full-length peroxinectin (AaPxt-1) secreted by is largely responsible oxidizing phenolic chemistries; AaPxt-1 driven native...
Plastics of various chemistries pollute global water bodies. Toxic chemicals leach with detrimental and often unpredictable impacts on the surrounding ecosystems. We found that seawater leachates plastic pre-production pellets from 7 recycle categories are acutely toxic to stage II barnacle nauplii; lethal concentration 50 (LC50s) were observed in 24-h dilutions ranging 0.007 2.1 mg/mL seawater. Based previous observations macro-organismal settlement fouling management coatings toxicities...
Methane seeps provide a variety of ecosystem services, including the provision complex habitat structures and high levels primary production, which can act as trophic support to non-seep-endemic species in an otherwise food-limited environment. The discovery hundreds on US Atlantic margin, ranging depth from ~50 1700m, provides opportunity assess depth-related differences seep-associated communities. Here, we use photo transects characterize megafaunal communities at six along comparing...
The decorator worm Diopatra cuprea , a tube-forming marine polychaete common to intertidal and shallow subtidal waters, modifies habitats it occupies through microreef construction algal gardening. While several studies have demonstrated that tubes are hotspots of biogeochemical activity (i.e., nitrogen sulfur cycling), is still largely unclear whether the tube microbiome differs compositionally from surrounding sediment what distinct functional processes microbiomes may have. To address...

Abstract Plastics are the most prevalent human-made substance in world and ubiquitous throughout all ecosystems. Microscopic plastic particles routinely ingested inhaled by humans other organisms. Despite frequency of exposures, little is known about their health consequences. Of particular concern additives -chemical compounds that mixed into plastics to improve functionality or unintentionally acquired during production use. Additives loosely bound polymer may be released exposures. These...
Global sustainability challenges, such as climate change and the plastics crisis, converge across disciplines involve diverse stakeholders.Given magnitude interconnected nature of problem-solvers must be trained disciplines.The United Nations Brundtland Commission's report "Our Common Future" articulated a definition "sustainability" in context development: ". ..development that meets needs present without compromising ability future generations to meet their own needs" [1].Although...
Marine plastic pollution is projected to grow in the coming years. We investigate polyvinyl chloride pre-production pellet consumption sea anemones. Results indicate that anemones consume up 83% of pellets readily and will all offered with 10 µl aqueous shrimp extract. Anemones retained consumed for 222±53 minutes. Feeding retention time decreased repeated feedings same new After feeding on one daily days, tin levels were at detection limits inconclusive Experiments 3 4. In Experiment 5,...
