Perturbations in ecosystems consist of a sequence of 2 events: the disturbance, marked by
the application of the disturbing forces, and the response shown by the biota to the damage …

Faced with widespread degradation of riverine ecosystems, stream restoration has greatly
increased. Such restoration is rarely planned and executed with inputs from ecological …

Publisher Summary This chapter draws attention to the similarities and differences in the
physical characteristics of floods and their ecological effects in upland and lowland …

Almost all rivers experience increases in discharge, although whether this results in a flood
depends on the size of the increase, channel morphology and hydrology. High flows have …

A patchy movement of surface stones during disturbance in streams has been proposed
from field observations, but few attempts have been made to quantify this phenomenon. If …

Disturbance is an important source of variability in species composition and diversity, but
application of disturbance models is contingent upon a very good understanding of the …

In recent years hydrologists and ecologists have come to realize the importance of
flowgenerated disturbances in streams and rivers. Such disturbances (floods and droughts) …

The harsh–benign model of community dynamics predicts that the impact of predation will
decline as abiotic conditions become more stressful to biota. Experiments were conducted to …

We conducted 2 experiments to examine how sorting, shape, and size of sediment grains
affected drift and mortality of the mayfly Deleatidium spp., the snail Potamopyrgus …

Studies were conducted on streams flowing through agricultural floodplains in south-eastern
Australia to quantify whether reductions in riparian canopy cover were associated with …
