151 Ehleringer, James R.Grupos funcionales en arbustos deserticos del norte de Chile, definidos sobre la base de las fuentes de agua utilizadasLa productividad primaria y la estructura de la vegetación en ecosistemas áridos están determinadas por la disponibilidad de agua. En un estudio realizado en el secano costero del norte-centro de Chile (29/43'S; 71/14'O, 300 m) se compararon los mecanismos de utilización de distintas fuentes de...Grupos funcionales; Functional groups; Arbustos deserticos; Desert shrubs; Fuentes de agua; Water sources; Water availability; Arid ecosystems; Pastoreo con caprinos; Goat overgrazing1999-01-01
152 Ehleringer, James R.Fuentes de aqua utilizadas por las plantas desérticas y su importancia en planes de manejo y restauración ecológicaEl agua es el factor más importante que afecta a la productividad primaria y la estructura de la vegetación en ecosistemas áridos.

156 Brown, Francis HaroldGeological development of the Omo-Turkana Basin during the pliocene and pleistocene epochsPliocene and Pleistocene deposits of the Omo-Turkana Basin extend from 6?N latitude to about 2?N latitude (-450 km), and laterally from about 35.5?E to 36.5?E. Sediments are brought to the basin by the Omo River which rises in Ethiopia, and by the Turkwel and Kerio Rivers which rise in Kenya and Uga...2004

158 Hillman, Nicholas WThe ethical dimensions of awarding financial aidAbstract In countries charging tuition fees, and those that are considering adopting tuition fee policies, recent economic conditions are making education less affordable and accessible for students (Johnstone & Marcucci, 2010; Schwarzenberger & Opheim, 2009). To combat these challenges, nations, ...2011

160 Davidson, Diane W.Effects of trenching on growth and survival of planted Shorea parvifolia seedlings under pioneer stands in a logged-over forestEffects of trenching on growth and survival of planted Shorea parvifolia seedlings under pioneer stands in a logged-over forest. We conducted an experiment to determine the value of trenching in reducing potentially negative effects of root competition on growth of Shorea parvifolia seedlings plant...Shorea parvifolia; Trenching; Dipterocarp seedlings; Enrichment planting; Pioneer stands; Root competition; Soil compaction; Sabah1998
161 Sekercioglu, CaganMapping functional traits: comparing bundance and presence-absence estimates at large spatial scalesEfforts to quantify the composition of biological communities increasingly focus on functional traits. The composition of communities in terms of traits can be summarized in several ways. Ecologists are beginning to map the geographic distribution of trait-based metrics from various sources of data,...2012-01-01
162 Lenart, Joshua B.The Uinta Express pipeline: a comprehensive research report conducted by students enrolled in CvEEN 3100 technical communicationsThe Uinta Express Pipeline is a proposed common carrier pipeline which would transport waxy crude oil extracted from the Uinta Basin in northeastern Utah to area refineries in North Salt Lake City. The proposed project would consist of a 12-inch, buried, insulated, carbon steel pipeline supported by...Uinta Express pipeline; Feasibility study; Waxy crude oil; Environmental impact assessment2015-02
163 Eddings, EricModified CPD Model for Coal Devolatilization at UCTT ConditionsTo study coal pyrolysis behavior at underground coal thermal treatment (UCTT) conditions, a modified CPD (M-CPD) model was developed and evaluated using two scales of experiments as well as two different coals, Utah Sufco and Illinois #6. Compared with the original CPD model, three major aspects wer...Coal; pyrolysis; modeling; underground heating2019
164 Ehleringer, James R.Patterns of local and nonlocal water resource use across the western U.S. determined via stable isotope intercomparisonsIn the western U.S., the mismatch between public water demands and natural water availability necessitates large interbasin transfers of water as well as groundwater mining of fossil aquifers. Here we identify probable situations of nonlocal water use in both space and time based on isotopic compari...2014-01-01
165 Sekercioglu, CaganCauses and consequences of bird extinctionsIncreased human domination of the planet has caused the declines and extinctions of countless species.
