Benthic Macroinvertebrates In Uvas Creek, California, Downstream Of A Reservoir, Carole Ann Foster
Benthic Macroinvertebrates In Uvas Creek, California, Downstream Of A Reservoir, Carole Ann Foster
Master's Theses
I sampled macroinvertebrates in May, July, and October 2008 in Uvas Creek, a reservoir-regulated stream in south Santa Clara County, California, to assess what factors (including canopy closure, turbidity, and stream flow) downstream of the reservoir were related to food availability for rearing juvenile Steelhead (Oncorhynchus mykiss). I found benthic and drifting macroinvertebrate biomass was considerably greater during most months in the more open-canopied two sites in the downstream reach as compared to the densely shaded, more turbid and silty two sites in the upstream reach. Abundance of important drifting aquatic invertebrates in May (chironomids, simuliids, and baetids) was proportional …
Macroinvertebrate-Driven Nutrient Recycling In Four Large Rivers, Matt A. Schroer
Macroinvertebrate-Driven Nutrient Recycling In Four Large Rivers, Matt A. Schroer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The cycling of nutrients is a fundamental process in streams and rivers, and scientists are increasingly recognizing the importance of animal communities to nutrient dynamics in these ecosystems. Despite growing evidence that animal excretion (i.e. urine) can supply limiting nutrients to primary producers in small streams, the importance of excretion is uncertain in large rivers. Accordingly, I used three estimation approaches based on past and new excretion rate data to determine nitrogen (N) and phosphorus (P) excretion inputs from insect communities in four large rivers (discharge > 10 cubic meters per second) in North America, and I compared these rates to …
Benthic Macroinvertebrate Community Responses To A Headwater Valley Restoration At Slabcamp Creek, Rowan Co., Kentucky, Nicholas Primo Revetta
Benthic Macroinvertebrate Community Responses To A Headwater Valley Restoration At Slabcamp Creek, Rowan Co., Kentucky, Nicholas Primo Revetta
Online Theses and Dissertations
The practice of stream restoration is well underway in the U.S., but there are few quantitative post-restoration studies of macroinvertebrate communities in restored streams in Kentucky. Slabcamp Creek, a first order tributary within the Licking River Basin, was recently restored to improve hydrology and degraded habitat caused by historical land use. The primary goal of my study was to begin baseline studies of the macroinvertebrate community in the restored section of Slabcamp Creek and to compare those findings to White Pine Branch (a pre-restoration control site) during the first post-restoration year. Specific objectives of my study were to: 1) report …
