| How many are there in a book? http://fittor.fun/xxnxx2o2o/ vporn.comn Views differ on what would happen if that biomass vanished. Bruce Harrison, an entomologist at the North Carolina Department of Environment and Natural Resources in Winston-Salem estimates that the number of migratory birds that nest in the tundra could drop by more than 50% without mosquitoes to eat. Other researchers disagree. Cathy Curby, a wildlife biologist at the US Fish and Wildlife Service in Fairbanks, Alaska, says that Arctic mosquitoes don't show up in bird stomach samples in high numbers, and that midges are a more important source of food. "We (as humans) may overestimate the number of mosquitoes in the Arctic because they are selectively attracted to us," she says. |
