| conservation in the first internal transcribed spacer (its1) region of hematodinium perezi (genotype iii) from callinectes sapidus . | hematodinium spp. infections have been reported from blue crabs callinectes sapidus in high-salinity waters of the usa from new jersey to texas. recently, h. perezi (genotype iii) has been proposed as the parasite species and genotype infecting blue crabs from virginia; however, it is unknown whether this same genotype is present in blue crabs from other locations. to address this question, we collected 317 blue crabs from massachusetts, virginia, georgia, florida, louisiana, and texas to test f ... | 2013 | 23482386 |
| evaluation of potential relationships between chemical contaminants in sediments and aquatic organisms from the lower passaic river, new jersey, usa. | the lower passaic river, new jersey, usa, a tidal tributary to newark bay and part of the new york and new jersey harbor estuary, is contaminated with a variety of persistent organic pollutants (pops) due to nearly two centuries of heavy industrialization and urbanization. resident aquatic organisms are exposed to, and can bioaccumulate, a variety of chemical contaminants from sediments, water and other organisms. in the present study, the relationships between selected pops detected in both sur ... | 2011 | 21520249 |
| incremental ecological exposure risks from contaminated sediments in an urban estuarine river. | estuaries in urban regions present unique environmental management challenges. ecosystems in urban estuaries are typically impacted by habitat loss and degradation, watershed modification, and nonpoint and point sources of many chemicals. restoring such systems requires an understanding of the relative contribution of various stressors to overall ecological conditions and an understanding of shifting patterns of stress over time. in this article, we present the results of a multiparameter enviro ... | 2005 | 16639904 |
