Coastal marine invertebrates will have to face the synergistic interactions of OA with other global and local stressors. One local factor, common in coastal environments, is trace element contamination. CO<sub>2</sub> vent sites are extensively studied in the context of OA and are often considered analogous to the oceans in the next few decades. The CO<sub>2</sub> vent found at Levante Bay (Vulcano, NE Sicily, Italy) also releases high concentrations of trace elements to its surrounding seawater, and is therefore a unique site to examine the effects of long-term exposure of nearby organisms to high <i>p</i>CO<sub>2</sub> and trace element enrichment <i>in situ</i>. The sea anemone <i>Anemonia viridis</i> is prevalent next to the Vulcano vent and does not show signs of trace element poisoning/stress. The aim of our study was to compare <i>A. viridis</i> trace element profiles and compartmentalization between high <i>p</i>CO<sub>2</sub> and control environments. Rather than examining whole anemone tissue, we analyzed two different body compartments—the pedal disc and the tentacles, and also examined the distribution of trace elements in the tentacles between the animal and the symbiotic algae. We found dramatic changes in trace element tissue concentrations between the high <i>p</i>CO<sub>2</sub>/high trace element and control sites, with strong accumulation of iron, lead, copper and cobalt, but decreased concentrations of cadmium, zinc and arsenic proximate to the vent. The pedal disc contained substantially more trace elements than the anemone’s tentacles, suggesting the pedal disc may serve as a detoxification/storage site for excess trace elements. Within the tentacles, the various trace elements displayed different partitioning patterns between animal tissue and algal symbionts. At both sites iron was found primarily in the algae, whereas cadmium, zinc and arsenic were primarily found in the animal tissue. Our data suggests that <i>A. viridis</i> regulates its internal trace element concentrations by compartmentalization and excretion and that these features contribute to its resilience and potential success at the trace element-rich high <i>p</i>CO<sub>2</sub> vent.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Trace element profiles of the sea anemone <i>Anemonia viridis</i> living nearby a natural CO<sub>2</sub> vent","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Ocean acidification; Trace elements; Metals; CO2 vent; Anemonia viridis","OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2017-09-20","DateCreate":"2017-09-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000347620200002","VABBcode":null,"OpenAcc":1,"DOI":"10.7717/peerj.538"},"refs":null,"anarec":{"AnaID":289285,"PubliDate":2014,"Pagination":"e538","XtraPublOfAnaID":null,"ISBN":null,"Volume":"2","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":242055,"SerRR":"PeerJ.
