A REVIEW OF THE REMOVAL OF ARUNDO DONAX FROM A RIPARIAN AREA WITHIN SAN TIMOTEO CANYON
… other non-native species had established the area, or if native species were able to grow in place of the removed <em>A. donax</em>. The previous removals included a combination of grinding large patches of <em>A. donax</em> and then foliar spraying, foliar spraying of uncut plants, and direct …

The Hillslope Hydrology of a Mountain Pasture: The Influence of Subsurface Flow on Nitrate and Ammonium Transport
… nitrate and ammonium to a naturally developing riparian area along Cartoogechaye Creek. Vertical and lateral transport of nitrate and ammonium were measured along three transect perpendicular to the stream. Transects were instrumented with time domain reflectometry (TDR) and porous cup tension …

Examination of small mammal diversity in the riparian areas of Walden, Tennessee
… B. Examination of Small Mammal Diversity in the Riparian Areas of Walden, Tennessee Thesis under the direction of Robert D. Keller, Ph.D., Assistant Professor of Biology It has been hypothesized that riparian zones are prime conservation habitats and can be used as indicators of general ecosystem …

Hedonic Valuation of Forested Riparian Buffers Along Rivers in Northwestern North Carolina
… owning a home along a river and tree coverage of riparian areas along rivers. The setting of this study is Ashe and Watauga Counties in Northwestern North Carolina and the two rivers that flow through those counties: New River and Watauga River. House sales form the basis of the hedonic models …

Behavioral Ecology and Associated Virology of Mosquito-Host Interactions in Southern California
… and also decreased with distance from water at a riparian area but not at an open water source lacking a vegetated border. Birds might therefore prefer elevated nests or roosts to avoid mosquitoes. The second study examined the anti-mosquito behaviors of budgerigars (Melopsittacus undulatus) in a …

Seasonal Variation in Whole Stream Metabolism across Varying Land Use Types
… I found that there is greater influence of local riparian land cover than watershed land cover on GPP and ER. Streams had varying annual GPP, but generally the peak in GPP occurred in late winter- early spring with lows in fall. GPP was most strongly influenced by the amount of available light, …

Up an Urban Creek: The Role of Development Patterns in Stream Health
Population growth in urban and sub-urban areas imposes increasing pressure on stream ecosystems. The "Urban Stream Syndrome" explains the observed negative trends in stream conditions associated with increasingly urbanized watersheds. Urban planners are challenged with addressing increased growth …

Nutrient Movement in Streamside Management Zones and Piedmont Streams Following Forest Fertilization
… taeda L.) plantations upslope from SMZ study areas throughout Buckingham Co., VA. Three replications of four SMZ treatment widths (30.5m, 15.2m, and 7.6m plus a thinned 15.2m SMZ) were studied using surface water collectors, cation/anion exchange membranes, lysimeters, and stream grab-samples. …

Correlation Between Bioassessments of Macroinvertebrates and Fishes and Natural Land Cover in Virginia Coastal Plain Watersheds
… whether a predictable relationship between areas of Unfragmented Natural Land Cover (UNLC) and biotic integrity could be established. I hypothesized that as the area of UNLC increased in a watershed at either the whole catchment or riparian scale, biotic indices measuring stream water and …

Assessment of silvicultural practices to improve survival and growth of pioneer and mid-successional hardwoods on old field restoration sites
… oak (Quercus phellos L.) planted on an old field riparian area in the Virginia Piedmont. American sycamore seedlings subjected to greenhouse flood preconditioning had 25% greater height and willow oak seedlings grown under normal greenhouse conditions had 18% greater diameter, but these greenhouse …

Identifying nitrate transport mechanisms and export dynamics using water age modeling and concentration-discharge relationships
… river discharge into three flow components (riparian flow, slow matrix flow, fast overland flow). Flow from riparian areas significantly contributed to low-flow events in the summer and fall, while overland and sub-surface fast-flow pathways were activated only during extreme-flow events in …

Spatial habitat variation in a Great Plains river: effects on the fish assemblage and food web structure
… isotope analysis. Satellite imagery indicated riparian habitat on the Kansas River was dominated by agriculture in the upper reaches (>35%) and tended to increase in urban land use in the lower reaches (>58%). Instream habitat complexity also decreased with increased urban area (<25%) becoming …

BRIDGING AQUATIC AND TERRESTRIAL ECOSYSTEMS: ECOLOGY OF SEMI-AQUATIC MAMMALS IN SOUTHERN ILLINOIS
… but are affected by bottom-up forces from the riparian system itself. The goal of this study was to identify variables that correlate with the presence of beaver (Castor canadensis), muskrat (Ondatra zibethicus), mink (Neovison vison), and river otter (Lontra canadensis), including their …
