Scorpion stings in urban environments in the central Arizona-Phoenix area: 1996-1997
Determination of what degree of human modification influences the frequency of scorpion stings by looking at the number of scorpion stings in different zip code areas of the Phoenix metropolitan area. Results from this study may be useful in making recommendations on land development so scorpion stings are minimal.

Institutional drivers of urban growth in the central Arizona-Phoenix area
The Institutional Drivers of Growth in Phoenix is currently ongoing. The purpose of the project is to understand how the complex mix of institutions, federal, state, and local, influence the pattern of growth in Phoenix. This year we focused on state trust land, specifically changing state trust land policy in Arizona and the west in general. We are approaching the state trust land sub-project by conducting qualitative research of policy archival documents. The assessment of state trust land referenda included a text and factor analysis of the policy dimensions. Additionally, the Institutional Drivers project has just begun to work in concert with �Socioecological Gradients and Land-Use Fragmentation: A Cross-Site Comparative Analysis.� The Institutional Drivers that we�ve gathered include annexation data, as well as preliminary assessment of growth management policy. In the American West, vast stocks of federally and state managed land and a relatively long history of self-governance and direct democracy unite to form heated public debates about use, management, and values. We investigate the nexus of these two threads of American politics, direct democracy and public land policies, through a qualitative study of ballot propositions on state trust land over the last century. A database of state trust land propositions was developed with forty-two propositions from fourteen states with over 90% from the West. Using word count as ideological placements we identified twenty-nine topics in the propositions. Text and principle component analysis reduced these to four dimensions of debate: 1) resource use procedures, 2) use of the fund, 3) management, and 4) investment. Additionally, we identified one issue that is receding in importance, resource extraction, while conservation and development concerns are emerging as new priorities. This study uses analysis of the policy language of ballot propositions to understand the political debates over state trust land over the p
A budget and spatial representation of Phosphorus in the central Arizona-Phoenix area
Phosphorus is a limited resource and a critical element in biogeochemistry. The raster datasets included here were created to show the spatial distribution of phosphorus stocks, accumulation, and throughput in the Central Arizona Phoenix Long Term Ecological Research study area. These rasters were created as the products of a phosphorus budget compiled within the CAP-LTER study area and are intended to be used by researchers studying biogeochemical cycles and sustainability. The raster of phosphorus stocks show the distribution of both abiotic and biotic phosphorus pools in the environment, which generally have long residence in the urban ecosystem. The accumulation and throughput raster show the likely areas where phosphorus will aggregate (inputs-outputs) over time and throughput shows areas with the highest inputs plus outputs of P. In addition to our final products we also include rasters used as variables to calculate the raw stocks, accumulation, and throughput rasters.

SGS-LTER Ecosystem Stress Area - Soil Carbon & Nitrogen in shortgrass steppe on the Central Plains Experimental Range in Nunn, Colorado, USA 1991, ARS Study Number 3
This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. Water, nitrogen, and water-plus-nitrogen at levels beyond the range normally experience by shortgrass steppe communities were applied from 1971 through 1975, plant densities were sampled through 1977, and then sampling resumed in 1982, with sampling frequencies changing from annually to every other year. The initial sampling from 1970 to 1974 showed that the water and water plus nitrogen treatments had the strongest effect on plant community structure, both treatments increased biomass, and exotic weed species were noted on the water plus nitrogen treatment. Later sampling from 1982 to 1991 showed a ten-fold increase in exotic weed species on the water plus nitrogen plots as compared to the controls (Milchunas and Lauenroth 1995), a community change that has persisted on this site due to a chronic elevation of soil nitrogen caused by a plant tissue/soil organic matter feedback mechanism (Vinton and Burke 1995). In 1998, Six new treatments were superimposed on the historic study site. The six new treatments were: control, sugar, lignin, sawdust, lignin and sugar, and sawdust and sugar.In 2010, plots will be sampled every 5 years. Our objective in this study is to examine how plant communities change through time and explore implications of these changes for monitoring
