concentrations of cadmium, lead, and zinc in fish from mining-influenced waters of northeastern oklahoma: sampling of blood, carcass, and liver for aquatic biomonitoring.	the tri-states mining district (tsmd) of missouri (mo), kansas (ks), and oklahoma (ok), usa, was mined for lead (pb) and zinc (zn) for more than a century. mining ceased more than 30 years ago, but wastes remain widely distributed in the region, and there is evidence of surface- and groundwater contamination in the spring river-neosho river (sr-nr) system of northeastern ok. in october 2001, we collected a total of 74 fish from six locations in the sr-nr system that included common carp (cyprinu ...	2005	15981034
a screening-level assessment of lead, cadmium, and zinc in fish and crayfish from northeastern oklahoma, usa.	the objective of this study was to evaluate potential human and ecological risks associated with metals in fish and crayfish from mining in the tri-states mining district (tsmd). crayfish (orconectes spp.) and fish of six frequently consumed species (common carp, cyprinus carpio; channel catfish, ictalurus punctatus; flathead catfish, pylodictis olivaris; largemouth bass, micropterus salmoides; spotted bass, m. punctulatus; and white crappie, pomoxis annularis) were collected in 2001--2002 from ...	2006	16791710
distribution, abundance, and genetic diversity of clinostomum spp. metacercariae (trematoda: digenea) in a modified ozark stream system.	abstract land-use alterations can have profound influences on faunal distributions, including host-parasite relationships. yellow grub trematodes ( clinostomum spp.) have complex life cycles involving 3 hosts: a snail, a fish or amphibian, and a bird. here, we analyze the distribution, prevalence, intensity, abundance, and genetic diversity of encysting metacercariae of clinostomum spp. in salamanders and fishes throughout an aquatic system that includes a natural ozark stream and man-made ponds ...	2011	21506775
landscape-level patterns of mercury contamination of fish in north texas, usa.	mercury (hg) is a toxic metal that is found in aquatic food webs and is hazardous to humans. an emerging conceptual model predicts that the areas of the landscape that have the potential to contain food webs with elevated concentrations of hg are those that receive high amounts of hg and sulfate deposition and have high coverage of forests and wetlands and low coverage of agriculture. the objective of the present study was to test this conceptual model using concentrations of hg in largemouth ba ...	2011	21647946
upstream effects of a reservoir on fish assemblages 45 years following impoundment.	fish assemblage structure, rarefied species richness, species diversity and evenness of assemblages upstream of a reservoir in oklahoma, u.s.a., were compared pre and post-impoundment as well as in contemporary collections from streams above and below the reservoir. there were significant shifts in assemblage structure between historical and contemporary collections above the reservoir but not between contemporary assemblages above and below the impoundment. indicator species analysis revealed t ...	2013	23639160
