Its purpose is to provide a forum for the publication of short research communications that provide important information but, due to their restricted focus, are not formatted in the manner of full research papers. All papers published under this heading will be peer reviewed. In order to follow the effects of pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorobenzenes (PCBs), and dioxins upon the European eel, we have developed an assay that quantifies hepatic cytochrome P4501A1 (CYP1A1) mRNA levels using real-time reverse transcription polymerase chain reaction (real-time RT-PCR). In this study, European eels were exposed to a diesel water soluble fraction (DWSF) in order to mimic environmental exposure to a mixture of organic pollutants. CYP1A1 mRNA levels were measured after 3, 6, 12, 24, 48, 72 and 156 h of exposure.

Gills (pair III) of fish exposed to 5.5 mg/L and 0.55 mg/L of copper sulfate and control without toxicant were placed in normal saline medium and, after rinsing, placed on a glass slide and observed under a Polyvar, Reichert-Jung light microscope attached to Ethovision-version 2.3 (Noldus Information Technology, Netherlands) through a Sony CCD IRIS camera (Model No: SSC-M370CE). Damage to secondary gill lamellae with loss of shape, necrosis, clubbing and fusion, shaft breakage, atrophy, curvature of tips, thick mucous sheathing and degeneration of rakers are observed in fish exposed to 5.5 mg/L of copper sulfate.

The Discussions are designed to generate focused debate around key topic areas, led by academic, government and industry experts, and are structured to produce definitive papers for peer review and publication in EBI's first-quarter issue of each publication year, albeit this year the papers will be published over the first two issues of 2007. The three Roundtables of the 14th ICEBI posed questions revolving around the chosen topic areas of Mercury Bioindicators, Marine Ecosystem-level Indicators, and Regulatory and Policy Uses of Bioindicators, and moved from “what we know” to “where we need to go” and “what are the policy implications from our discussions and conclusions.” The following paper on coral reef indi...","PeriodicalId":92776,"journal":{"name":"Environmental bioindicators","volume":"2 1","pages":"35-46"},"PeriodicalIF":0.0,"publicationDate":"2007-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15555270701263200","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60024193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bivalve mollusks are often used as bioindicators to monitor contaminant body burdens and are employed globally in pollution monitoring and as sentinels of environmental quality. The prevalence of proliferating cells in tissues of the eastern oyster, Crassostrea virginica, (n = 10) was investigated by using immunohistochemical staining of proliferating cell nuclear antigen (PCNA) and by flow cytometric analysis of DNA in cell cycle phases. The PCNA protein is highly conserved and central to DNA synthesis in dividing cells. This protein was detected by using a commercial antibody in the histological staining of gills, mantle, digestive gland, stomach, and labial palps. Cells obtained from these same organs and from the hearts of the oysters were used for flow cytometry (FCM). The proportions of nuclei in the S plus G2/M and G2/M fractions were compared with percentages of PCNA-positive cells scored through microscopy. ...","PeriodicalId":92776,"journal":{"name":"Environmental bioindicators","volume":"1 1","pages":"177-190"},"PeriodicalIF":0.0,"publicationDate":"2006-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15555270600868174","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60024073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metals were found to be selectively distributed among the holothuroid body compartments (i.e. body wall, gut, and haemal system). Among the sources of variation taken into account, the major part of the variability observed in metal concentrations was associated to the body compartment factor, then to the seasonal one and, finally, to the geographical and bathymetric factors. Our results suggest that, if one uses H. tubulosa as a bioindicator species for surveying and monitoring metal contamination in the Mediterranean P. oceanica meadows, attention should be paid to compare only concentrations measured in the same body compartments of individuals collected during the same period of the year. Body compartments that should be preferably considered for me...","PeriodicalId":92776,"journal":{"name":"Environmental bioindicators","volume":"1 1","pages":"268-285"},"PeriodicalIF":0.0,"publicationDate":"2006-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15555270601034388","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60023842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
