relation of lake ontario fish consumption, lifetime lactation, and parity to breast milk polychlorobiphenyl and pesticide concentrations.lactating female members and spouses of male members of the new york state angler cohort who agreed to provide breast milk samples were the subjects of this study. questionnaires were provided to participants focusing on lake ontario fish consumption, reproductive history, and lactation history. milk samples were analyzed for 77 polychlorinated biphenyls (pcb) congeners, 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (dde), a metabolite of dichlorodiphenyltrichloroethane (ddt), hexachlorobenzene ...199910092430
parental consumption of contaminated sport fish from lake ontario and predicted fecundability.wildlife studies suggest that consumption of contaminated fish from the great lakes may expose humans to polychlorinated biphenyls and persistent chlorinated pesticides. to assess whether time to pregnancy or fecundability is affected, we conducted a telephone survey in 1993 with female members of the new york state angler cohort study who were considering pregnancy between 1991 and 1994 (n = 2,445). among the 1,234 (50%) women who became pregnant, 895 (73%) had a known time to pregnancy. upon e ...200010874544
least-cost transportation networks predict spatial interaction of invasion vectors.human-mediated dispersal among aquatic ecosystems often results in biotic transfer between drainage basins. such activities may circumvent biogeographic factors, with considerable ecological, evolutionary, and economic implications. however, the efficacy of predictions concerning community changes following inter-basin movements are limited, often because the dispersal mechanism is poorly understood (e.g., quantified only partially). to date, spatial-interaction models that predict the movement ...201021265458
the effects of regional angling effort, angler behavior, and harvesting efficiency on landscape patterns of overfishing.we used a coupled social-ecological model to study the landscape-scale patterns emerging from a mobile population of anglers exploiting a spatially structured walleye (sander vitreus) fishery. we systematically examined how variations in angler behaviors (i.e., relative importance of walleye catch rate in guiding fishing site choices), harvesting efficiency (as implied by varying degrees of inverse density-dependent catchability of walleye), and angler population size affected the depletion of w ...201122073644
blood mercury levels among ontario anglers and sport-fish eaters.we conducted two surveys of ontario (canada) fishers: a stratified sample of licensed anglers in two lake ontario communities (anglers, n=232) and a shore and community-based sample in five great lakes' areas of concern (aoc eaters, n=86). among the 176 anglers consuming their catch, the median number of sport-fish meals/year was 34.2 meals and 10.9, respectively, in two communities, with a mean blood total mercury level among these sport-fish consumers of 2.8 microg/l. the vast majority of fish ...200415220065
paternal lake ontario fish consumption and risk of conception delay, new york state angler cohort.the aquatic ecosystems of the great lakes are contaminated with a variety of compounds, some of which are considered reproductive toxicants. few studies of paternal fish consumption and reproductive endpoints have been undertaken and serve as the impetus for study. standardized telephone interviews were conducted with 2445 female members of the new york state angler cohort (82% response) to update reproductive profiles and to ascertain specific information on time-to-pregnancy (ttp). the study s ...199910092415
