Agenda: Uncovering The Hidden Resource: Groundwater Law, Hydrology And Policy In The 1990s, University Of Colorado Boulder. Natural Resources Law Center, Rocky Mountain Ground-Water Conference (1992), Colorado Ground-Water Association
Uncovering the Hidden Resource: Groundwater Law, Hydrology, and Policy in the 1990s (Summer Conference, June 15-17)
Sponsored by Natural Resources Law Center, University of Colorado School of Law and the Rocky Mountain Ground-Water Conference, organized by the Colorado Ground-Water Association.
Faculty for the conference included University of Colorado School of Law professor Lawrence J. MacDonnell.
Nearly half the people in the United States rely on groundwater as their primary water source. As demands for groundwater grow, it becomes increasingly important for lawyer and technical professionals to understand the legal and hydrologic issues arising in groundwater development, use, and protection. These issues will be the focus of the Center's thirteenth annual summer program, June 15-17, 1992.

Carbon And Nitrogen Isotopic Signatures Of Bat Guanos As A Record Of Past Environments, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya
Carbon And Nitrogen Isotopic Signatures Of Bat Guanos As A Record Of Past Environments, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya
WM Keck Science Faculty Papers
Carbon and nitrogen isotope ratios were measured for various ecogeochemical samples relevant to bat guano ecosystems. In particular, ca. 800-year-old subfossil guano from Jackson's Bay Cave Compex, Jamaica, yielded ratios similar to the modern guano from other Jamaican bat caves but quite different from modern guano of the same area. Diagenetic change and differences in bat food habits were unlikely explanations for the observation. Instead, insects that feed on C4 and CAM plants were the main prey for the bats in present Jackson's Bay area, while the ultimate source of organic matter for bats in other Jamaican caves and for …
Nitrogen And Carbon Isotope Studies Of A Bat Guano Core From Eagle Creek Cave, Arizona, Usa, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya
Nitrogen And Carbon Isotope Studies Of A Bat Guano Core From Eagle Creek Cave, Arizona, Usa, Hiroshi Mizutani, Donald A. Mcfarlane, Yuko Kabaya
WM Keck Science Faculty Papers
Nitrogen and carbon isotope ratios were studied in a stratified deposit of guano of Mexican Free-tailed bats in Eagle Creek Cave, Arizona, U.S.A. Little diagenetic change was observed over the 25-year time span of the guano deposit. High aridity and reduced circulation of air in the cave are hypothesized to have slowed the normally rapid decomposition of the excreta and the subsequent escape of resultant ammonia. The results suggest the high dependency of the speed of diagenetic change on specific physical and other conditions of the caves and indicate that great care need be exercised in the interpretation of the …
