Cartmill, Andrew David (Texas A&M University, 2005-11-01)High bicarbonate (HCO3-) content and associated high pH of irrigation water is detrimental to plant growth. Sustain ableagricultural/horticultural production will increasingly have to rely on economically feasible and ...
-
Kantola, Ilsa Beth (2012-07-16)Woody plant encroachment is a globally-prevalent vegetation change phenomenon that has shifted grass-dominated ecosystems to mixed grass and woody plant matrices over the last century. In the Rio Grande Plains of Texas, ...
-
Herrmann, Lori Lynn (1995)The abundance of woody plants has increased in recent history in many grassland and savanna ecosystems throughout the world. Woody plants involved in this successional process are often capable of N₂-fixation, such as ...
-
Franzluebbers, Kathrin (Texas A&M University. Libraries, 1994)Lack of organic input is a major factor contributing to the deterioration o f the sandy Alfisols and Entisols in the Sahelian zone of West Africa. Cowpea [Vigna unguiculata (L.) Walp.] has great potential as green manure ...
-
Storlien, Joseph Orgean (2013-06-13)Enhanced interest in biofuel production has renewed interest in bioenergy crop production within the United States. Agriculture’s role in biofuel production is critical because it has the potential to supply renewable ...
-
Lenoir, Katherine Judith (2013-04-29)Junipers and pines exhibit contrasting patterns of growth decline and mortality with climate change-type warming and drought; yet, the underlying physiological mechanisms are not fully understood. Does warming exacerbate ...
-
Chandrasena, Rajapakshage Inoka Ilmi (Texas A&M University, 2004-09-30)The broad objective of this thesis involves investigation of the role agriculture might play in a society wide greenhouse gas emissions reduction effort. Specifically, the breakeven price for carbon emission offsets is ...
-
Biederman, Lori Ann (2009-05-15)Increasing interest among restoration ecologists exists in developing strategies that stimulate biotic interactions and promote self-regulation in restored systems. These approaches should target above- and belowground ...
-
Saenz, Daniel (Texas A&M University, 2005-02-17)Multiple ecological factors can simultaneously affect species activity and community structure. The goal of my dissertation was to examine the effects of abiotic factors, biotic factors, and succession on anuran communities. ...
-
Zhang, Yang (2016-05-02)Wood debris is an important C pool in forest ecosystems. Understanding the controls on wood decomposition is necessary for predicting the response of forest ecosystem carbon cycling to management and climate. The productivity ...
-
Rothlisberger, Katie Lynn (2012-02-14)Oilseed crops are being widely evaluated for potential biodiesel production. Seed meal (SM) remaining after extracting oil may have use as a bioherbicide or organic fertilizer. Brassicaceae SM often contains glucosinolates ...
-
Caster, Stephen (2010-01-16)A two-year study was conducted in which soil solution, drainage water, and soil core samples were taken from three turfgrass test plots and two sports fields, located on the Texas A&M University campus. The goal was to ...
-
Da Ros Carvalho, Henrique (2019-06-04)Epicuticular waxes are hypothesized to enable plants to cope with drought. There is evidence that waxes alter the energy balance of plants through increase in reflectivity of solar radiation and through decrease in conductance ...
-
Torres-Poche, Zaria (2017-07-20)The largest tropical lake in Mexico, Lake Chapala, is a major fishery and a recipient of many contaminants (industrial and agricultural) via the Lerma River. The objectives were to evaluate concentrations of mercury (Hg), ...
-
Jacoby, Freddy J. (Texas A&M University, 2006-08-16)Phosphorus (P) inputs into water reservoirs are the primary cause for accelerated eutrophication affecting water quality. Attempts are underway to regulate inputs originating from concentrated animal feeding operations ...
-
Hubbard, John Andrew (Texas A&M University, 2004-09-30)Grasslands are characterized by recurring disturbances such as fire and grazing occurring against a background of topoedaphic heterogeneity and climatic variability. The result is a complex, multi-scaled disturbance regime, ...
-
Harris, Wylie Neal (Texas A&M University, 2006-08-16)Plant production and soil microbial biomass (SMB) in grassland ecosystems are linked by flows of carbon (C) and nitrogen (N) between the two groups of organisms. In native mixed grasslands of the southern Great Plains, ...
-
Egilla, Jonathan Nda (Texas A&M University. Libraries, 1994)The effect of potassium (K) and drought stress on leaf elemental concentration, water relations, gas exchange, instantaneous water-use efficiency [(WUEj), the ratio of photosynthesis to transpiration], long-term water-use ...
-
Shen, Li (2009-05-15)With the increase in human population, water resources have become more and more precious. A comprehensive study of water yield characteristics is imperative, especially in water-limited semiarid regions. The objective of ...
-
Hollister, Emily Brooke (2009-05-15)In the southern Great Plains, the encroachment of grassland ecosystems by mesquite (Prosopis glandulosa), is widespread, and prescribed fire is commonly used in its control. Despite this, substantial quantitative information ...
