More than 280 species of caddisflies (Trichoptera), representing 80
genera in 16 families, are known to occur in Oregon. Detailed distribution
records within the state are given, as well as the known geographic range
for each species. Biological information, such as life cycle, habitat
preference, flight period, and larval feeding...
In order to restore conifers in hardwood dominated riparian forests 25% of the
experimental reach forests alongside four streams in western Oregon was clearcut.
Clearcutting removed 400 m without residual buffers from a 1600-m streamside forest
reach in patchcuts spanning 100 and 200 meters. To assess the cumulative and direct...
Aquatic insects that emerge out of streams to mate represent a potential energy
flux to terrestrial food webs. The relative success of an individual aquatic adult insect
is whether it survives long enough to produce offspring, i.e. mate and return to the
stream to oviposit eggs. Some characteristics of the...
This study was an investigation of lotic macroinvertebrate distribution in northeastern Oregon at two different spatial and biological scales. Examination of assemblages at a limited spatial scale revealed relationships with natural and disturbance gradients and led to questions about distribution of a population at broader spatial scales. In a 16...
