This dataset accompanies the manuscript Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities in Water Resources Research.
Benthic macroinvertebrates were collected from samples taken annually during the first two weeks of August from 2002-2007 and again in 2017 at six sites in the South Fork McKenzie...
Twenty-five gabion-type structures across the main stem and
tributaries of the Siuslaw River in the Oregon Coastal Range, installed
to expand the available spawning area for fish, were investigated for
their ability to perform gravel control functions such as trapping bedload
carried by the stream or holding gravel placed behind...
This thesis reports a portion of a general ecological study of
a stream under conditions of controlled flow and low levels of organic
enrichment. It is concerned with the effects of experimental variations
of light intensity and concentration of soluble organic enrichment
imposed on seasonal variations of temperature and total...
An impounded estuary was employed to study primary productivity, community respiration, and community structure as they
related to seasonal and temporal succession, salinity, and water
temperature. Plankton metabolism was studied by means of the
light-and dark-bottle technique. Benthic community metabolism
was determined by using the "diurnal oxygen curve" method.
Four...
Laboratory stream communities in simulated old growth second
order streams were sampled June 1984 and June 1985 to advance an
understanding of their organization and development, and their
response to an environmental perturbance, the toxicant dieldrin. An
interpenetrating hierarchical view of habitats and community
subsystems was taken to conceptualize community...
New approaches are needed to quantify and understand spatial patterns of stream fishes and their environment. Concepts in riverine ecology emphasize the importance of thermal zones and gradual longitudinal changes in physical habitat and biota, but little is known about spatial variability within the river continuum. I present a conceptual...
The lack of cost-effective, reliable sampling methods for many wetland
characteristics hinders efforts to describe the structural and functional
properties of wetlands. This study evaluated techniques for sampling the
subsurface hydrology and invertebrates of freshwater wetlands. The depth of
rusting on mild steel rods was compared with water well measurements...
