(1) Sampling reaches were selected to include riffle habitats with substrate composed primarily of cobble, gravel, and boulder.(2) Given their natural size advantage, salmon are competitively dominant and increase the proportion of trout occupying riffle habitat, whereas trout have little effect on habitat selection by salmon.(3) the loudest sound was the constant riffle of paper as people looked at the agendas(4) The stream has now become nothing more than a sediment sluice with rock pools filled-in with sand and gravel, and former riffle reaches submerged in sediment.(5) Faintly, though not frequently, a riffle of doubt perturbs Krugman's chipmunk paeans to the Clinton Age.(6) One minute you're in a sharp, spluttering, stony riffle , and then you're in a swift, frictionless, swirling run, or in a deep slow pool of long vowels and slow consonants.(7) We limited our selection of sites to approximately second to fourth order streams, and selected sites with naturally-occurring riffle zones having gravel-cobble-boulder substrate.(8) A rainbow stud, resplendent in his best dress uniform, stakes out and defends his riffle against all invaders, threatening would-be rivals with vicious fin-to-fin combat.(9) They added more than 20 riffle weirs, 15 post vanes, and 80,000 willows to slow water down, protect streambanks, increase habitat and raise the water table.(10) At night, some subdominant fish can be observed in pool and riffle margins, although numbers are low relative to the number of fish active by day.(11) Indeed, to keep games moving along at a brisk pace, blackjack dealers don't always take the time to perform the seven riffle shuffles necessary to achieve an adequate level of mixing.(12) This boat is fun in a class 1 riffle , and once you get the hang of it, you can use it to run up to class 3 rapids.(13) They may riffle or strip too high and, again, inadvertently expose cards allowing you to know their approximate location.(14) The channel morphology was characterized by alternating riffle , run, and pool segments that averaged 10-15 m in length.(15) just a riffle through the books(16) I'd sit down with Rick or Barry and make them riffle through the book of their choice.
