| an evaluation of the mosquitofish, gambusia affinis, and the inland silverside, menidia beryllina, as mosquito control agents in california wild rice fields. | the mosquitofish, gambusia affinis, and the inland silverside, menidia beryllina, were evaluated in experimental, one-tenth hectare wild rice plots in lake county, california, for their impact on densities of culex tarsalis, anopheles freeborni and anopheles franciscanus. gambusia affinis were tested at 0.6 and 1.7 kg/ha and the silversides at ca. 0.9 kg/ha. the silversides did not survive well in the rice field system and none of the silverside guts examined contained mosquito larvae. the mosqu ... | 1987 | 2904970 |
| spatiotemporal trends in fish mercury from a mine-dominated ecosystem: clear lake, california. | clear lake, california, usa, receives acid mine drainage and mercury (hg) from the sulphur bank mercury mine, a u.s. environmental protection agency (u.s. epa) superfund site that was active intermittently from 1873 to 1957 and partially remediated in 1992. mercury concentrations were analyzed primarily in four species of clear lake fishes: inland silversides (menidia beryllina, planktivore), common carp (cyprinus carpio, benthic scavenger/omnivore), channel catfish (ictalurus punctatus, benthic ... | 2008 | 19475924 |
| changes in fish diets and food web mercury bioaccumulation induced by an invasive planktivorous fish. | the invasion, boom, collapse, and reestablishment of a population of the planktivorous threadfin shad in clear lake, california, usa, were documented over a 20-year period, as were the effects of changing shad populations on diet and mercury (hg) bioaccumulation in nearshore fishes. threadfin shad competitively displaced other planktivorous fish in the lake, such as inland silversides, young-of-year (yoy) largemouth bass, and yoy bluegill, by reducing zooplankton abundance. as a result, all thre ... | 2008 | 19475926 |
| changes in menidia beryllina gene expression and in vitro hormone-receptor activation after exposure to estuarine waters near treated wastewater outfalls. | fishes in estuarine waters are frequently exposed to treated wastewater effluent, among numerous other sources of contaminants, yet the impacts of these anthropogenic chemicals are not well understood in these dynamic and important waterways. inland silversides (menidia beryllina) at an early stage of development [12 days posthatch (dph)] were exposed to waters from two estuarine wastewater-treatment outfall locations in a tidal estuary, the sacramento/san joaquin delta (california, usa) that ha ... | 2016 | 27155869 |
