Agave salmiana Plant Communities in Central Mexico as Affected by Commercial Use

Creator:: Martinez Salvador, Martin, Mata-Gonzalez, Ricardo, Morales Nieto, Carlos, and Valdez-Cepeda, Ricardo
Abstract:: Agave salmiana is a native plant species harvested for the commercial production of mezcal (Agave spirits) in the highlands of central Mexico. The objective of this study was to identify vegetation changes in natural communities where A. salmiana has been differentially harvested for commercial purposes. Three plant community categories were...

Agronomic performance of six winter wheat dwarfing sources when crossed to isogenic lines for Norin 10 Rht loci

Creator:: Pedretti, Ricardo
Abstract:: Six genetically diverse dwarfing sources of winter wheat were compared to four isogenic lines for the height reducing genes Rht₁ and Rht₂. Parents and generations through the F₃ including backcrosses to the respective parents were analyzed. Seedling response to gibberellic acid and tests for allelism for plant height were employed...

Quantifying spatial differences in metabolism in headwater streams

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Argerich, Alba
Abstract:: Stream functioning includes simultaneous interaction among solute transport, nutrient processing, and metabolism. Metabolism is measured with methods that have limited spatial representativeness and are highly uncertain. These problems restrict development of methods for up-scaling biological processes that mediate nutrient processing. We used the resazurin–resorufin (Raz-Rru) tracer system to estimate metabolism...

Quantitative Relationship between Resazurin and Respiration in Stream Ecosystems

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, Argerich, Alba, Acker, Sarah, and Myrold, David
Abstract:: After three decades of active research in hydrology and stream ecology, the connection between solute transport, stream metabolism and nutrient dynamics is still unresolved. This existing gap obscures the functionality of stream ecosystems and how they interact with other landscape processes. To date, determining rates of metabolism is accomplished with...

Measuring aerobic respiration in stream ecosystems using the resazurin-resorufin system

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Myrold, David D.
Abstract:: The use of smart tracers to study hydrologic systems is becoming more widespread. Smart tracers are compounds that irreversibly react in the presence of a process or condition under investigation. Resazurin (Raz) is a smart tracer that undergoes an irreversible reduction to resorufin (Rru) in the presence of cellular metabolic...

A two-way nested simulation of the oceanic circulation in the Southwestern Atlantic

Creator:: Combes, Vincent and Matano, Ricardo P.
Abstract:: This article presents the results of a high-resolution (1/12°), two-way nested simulation of the oceanic circulation in the southwestern Atlantic region. A comparison between the model results and extant observations indicates that the nested model has skill in reproducing the best-known aspects of the regional circulation, e.g., the volume transport...

Western Land Managers will Need all Available Tools for Adapting to Climate Change, Including Grazing: A Critique of Beschta et al.

Creator:: Svejcar, Tony, Boyd, Chad, Davies, Kirk, Madsen, Matthew, Bates, Jonathan D., Sheley, Roger, Marlow, Clayton, Bohnert, David W., Borman, Mike, Mata-Gonzalez, Ricardo, Buckhouse, John, Stringham, Tamzen, Perryman, Barry, Swanson, Sherman, Tate, Kenneth, George, Mel, Ruyle, George, Roundy, Bruce, Call, Chris, Jensen, Kevin, Launchbaugh, Karen, Gearhart, Amanda, Vermeire, Lance, Tanaka, John, Derner, Justin, Frasier, Gary, and Havstad, Kris
Abstract:: In a previous article, Beschta et al. (Environ Manag 51(2):474–491, 2013) argue that grazing by large ungulates (both native and domestic) should be eliminated or greatly reduced on western public lands to reduce potential climate change impacts. The authors did not present a balanced synthesis of the scientific literature, and...

Coupled transport and reaction kinetics control the nitrate source-sink function of hyporheic zones

Creator:: Zarnetske, Jay P., Haggerty, Roy, Wondzell, Steven M., Bokil, Vrushali A., and Gonzalez-Pinzon, Ricardo
Abstract:: The fate of biologically available nitrogen (N) and carbon (C) in stream ecosystems is controlled by the coupling of physical transport and biogeochemical reaction kinetics. However, determining the relative role of physical and biogeochemical controls at different temporal and spatial scales is difficult. The hyporheic zone (HZ), where groundwater–stream water...

On the Upwelling of Downwelling Currents

Creator:: Matano, Ricardo P. and Palma, Elbio D.
Abstract:: The term “downwelling currents” refers to currents with a downslope mass flux in the bottom boundary layer. Examples are the Malvinas and Southland Currents in the Southern Hemisphere and the Oyashio in the Northern Hemisphere. Although many of these currents generate the same type of highly productive ecosystems that is...
