Witryna1 lis 2003 · The combination of human population growth, increased water usage, and limited groundwater resources often leads to extensive damming of rivers and streams on tropical islands. Witrynaan impounded stream is disturbed at the reach or val-ley segment scale (Frissell et al., 1986). Lake (2000) indicated that ﬂow cessation, mainly through drought, reduces water quality such that only the more toler-ant macroinvertebrate taxa are able to colonize and survive.
