Data product for "Effects of water and nitrogen availability on nitrogen contribution by the legume, Lupinus argenteus Pursh"

Datasets Posted on: August 27, 2015
We conducted a greenhouse experiment to examine the separate and interacting effects of water and nitrogen (N) availability on biomass production, tissue N concentration, nodulation, nodule activity, and rhizodeposition of Lupinus argenteus (Pursh), a legume native to sagebrush steppe. Plants were grown in a replicated, randomized block design with three levels of water and four levels of N.

Data product for "Influence of a native legume on soil N and plant response following prescribed fire in sagebrush steppe"

Datasets Posted on: August 27, 2015
We examined the effects of prescribed fire and legume presence in Underdown Canyon located in the central Great Basin, Nevada, USA. We examined three treatments - one year post-burn, three years post-burn and unburned control in three replicate blocks. Within each treatment we measured density, biomass, cover, and nutrient content of a native legume, Lupinus argenteus (Pursh).

Data product for "Nitrogen level and legume presence affect competitive interactions between a native and invasive grass"

Datasets Posted on: August 27, 2015
We conducted a greenhouse experiment to investigate effects of the native N2-fixing legume, L. argenteus, on competitive interactions between seedlings of the non-native annual grass, B.tectorum, and a native perennial grass, E. multisetus, over a gradient of nitrogen (N) availability.

Data product for "Role of a native legume in facilitating native vs. invasive species in sagebrush steppe before and after fire"

Datasets Posted on: August 27, 2015
We conducted a field experiment near Reno, Nevada to determine if the native legume, Lupinus argenteus, is able to facilitate seedling establishment in an unburned and burned community in sagebrush steppe. We chose six treatments to identify specific mechanisms by which L.

Data product for "Anticipated climate warming effects on Bull Trout habitats and populations across the Interior Columbia River Basin"

Datasets Posted on: August 27, 2015
This archive contains the data necessary to complete the general processing steps as outlined in the associated publication, Rieman et al. (2007).

Geomorphology influences extent and composition of riparian plant communities at the watershed scale in central Nevada

Datasets Posted on: August 27, 2015
We conducted an observational study of the relationships between watershed-scale geomorphology and riparian vegetation using solely digital datasets. Watershed morphometry and geology were derived from Digital Elevation Models (DEMs) and geologic maps. Riparian corridors were classified into five vegetation types (riparian forest, riparian shrub, wet/mesic meadow, dry meadow, and shrub dry meadow) using high-resolution aerial photography.

Relationships between riparian vegetation and geomorphic process zones in the Toiyabe mountain range in Nevada

Datasets Posted on: August 27, 2015
We conducted a field observational study to investigate the ecological significance of the "process zone" geomorphic classification scheme for riparian ecosystem distribution, composition, and structure. We measured geomorphic characteristics at multiple scales in order to better understand relationships between geomorphology and riparian vegetation, and to suggest improvements to the classification scheme.

Central Nevada meadow characterization

Datasets Posted on: August 27, 2015
This data publication contains a geodatabase as well as tabular digital data for Central Nevada meadows that were based on data collected in the summer of 2005 and 2006. The geodatabase includes plant community arrangements, streams, springs, and watersheds within each meadow.

Tenderfoot Creek Experimental Forest water quality data: 1992-2009

Datasets Posted on: August 27, 2015
This data publication contains water quality data analyzed from water samples taken at 11 hydrologic flumes on the Tenderfoot Creek Experimental Forests from 1992 to 2009.

Tenderfoot Creek Experimental Forest 15 minute streamflow data: 2000-2009

Datasets Posted on: August 27, 2015
This data publication contains 15 minute stream flow rates (cubic feet per second) for 11 flumes in the upper Tenderfoot Creek watershed from 2000 to 2009. Two sub watersheds: Sun Creek and Spring Park Creek had experimental shelterwood harvests in 1999 and 2000. Portions of these units were prescribed burned between 2001 and 2003. Two adjacent subwatersheds: Bubbling Creek and Stringer Creek serve as controls.
