Comparison of Regional and Statewide Impacts on Salinity Mitigation in the Arkansas River Valley

The Arkansas River in Colorado has a major salinity problem, due to agricultural runoff caused by irrigation. It is necessary to see how on-farm net sales, regional and state employment and income levels are affected by alternative aquifer recharge rates. The positive impacts were greatest for the 40% recharge rate.Resource /Energy Economics and Policy,

Tourists’ and Residents’ Values for Maintaining Working Landscapes of the ‘Old West’

The value of agricultural landscapes to tourists and local residents is not captured in the marketplace. Landowners provide stewardship over these valuable landscape attributes, but do not receive any ‘uncaptured’ value. Through real estate markets, it is easy to reveal the value of converting landscapes, but less easy to understand the value of not converting them. Redistributive policies have the potential to provide incentives to landowners to act on behalf of these other stakeholders by lowering the opportunity cost of (raising the returns to) open lands stewardship. This article will examine this issue for a rural county in Colorado. Tourist and resident demographics and travel behavior will be identified. The value of ranch open space that currently is not reflected in the market will be estimated and further discussed in terms of its implications for the local economy. Policy implications for the local decision makers to capture this currently ‘uncaptured’ value of ranch open space will be briefly explored

BENEFITS OF CONTROLLING SALINE WATER IN COLORADO

The Arkansas River in Colorado is confronted with a salinity issue; the majority of this salinity problem is due to agricultural runoff caused by irrigation. Reducing applications of irrigation water through adoption of more technically efficient irrigation systems is one means of improving water quality in the Arkansas River basin. This research uses positive mathematical programming to model the cropping practices of the farms along the Arkansas River. It examines the affect of acreage and profit levels of these farms given the choice of changing their irrigation technologies.Environmental Economics and Policy,

Single-nucleus expression characterization of non-enhancing region of recurrent high-grade glioma

BackgroundNon-enhancing (NE) infiltrating tumor cells beyond the contrast-enhancing (CE) bulk of tumor are potential propagators of recurrence after gross total resection of high-grade glioma.MethodsWe leveraged single-nucleus RNA sequencing on 15 specimens from recurrent high-grade gliomas (n = 5) to compare prospectively identified biopsy specimens acquired from CE and NE regions. Additionally, 24 CE and 22 NE biopsies had immunohistochemical staining to validate RNA findings.ResultsTumor cells in NE regions are enriched in neural progenitor cell-like cellular states, while CE regions are enriched in mesenchymal-like states. NE glioma cells have similar proportions of proliferative and putative glioma stem cells relative to CE regions, without significant differences in % Ki-67 staining. Tumor cells in NE regions exhibit upregulation of genes previously associated with lower grade gliomas. Our findings in recurrent GBM paralleled some of the findings in a re-analysis of a dataset from primary GBM. Cell-, gene-, and pathway-level analyses of the tumor microenvironment in the NE region reveal relative downregulation of tumor-mediated neovascularization and cell-mediated immune response, but increased glioma-to-nonpathological cell interactions.ConclusionsThis comprehensive analysis illustrates differing tumor and nontumor landscapes of CE and NE regions in high-grade gliomas, highlighting the NE region as an area harboring likely initiators of recurrence in a pro-tumor microenvironment and identifying possible targets for future design of NE-specific adjuvant therapy. These findings also support the aggressive approach to resection of tumor-bearing NE regions
