I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects on key environmenta ...

Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to describe benthic ma ...

Benthic macroinvertebrate production

Bissonnette, Pam et al. [1973]

Macroinvertebrates were sampled on a regular basis from March to October1973. A relationship between chironomid length and biomass was established.Production equations to be used for these insects are reported. A similarlength/weight relationship is presently being explored for the oligochaetes.A proposal is made for calculating their production as well as for sphaeridsand P. affinis. Sampling ...

This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the community and functional ...

Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon, U ...

Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead(Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunctionwith selected physicochemical data, from representative wetland types at a mining site withinSalt Lake County, Utah, USA. The selected field sites included Oolitic Pond (lentic) and LeeCreek (lotic), which are moderately contam ...
