| 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 |
| novel concordance between geographic, environmental, and genetic structure in the ecological generalist prickly sculpin (cottus asper) in california. | ecological generalists may contain a wealth of information concerning diversity, ecology, and geographic connectivity throughout their range. we explored these ideas in prickly sculpin (cottus asper), a small generalist freshwater fish species where coastal forms have potentially undergone radiations into inland lacustrine and riverine environments. using a 962bp cytochrome b mtdna marker and 11 microsatellites, we estimated diversity, divergence times, gene flow, and structure among populations ... | 2016 | 27489253 |
