A Multi-Decadal Precipitation Evaluation for Namibia Using Satellite, Model, and Ground-Based Data
(2019-06-18)Precipitation in southern Africa exhibits high variability with rain often falling in an intense deluge or not at all. Considerable research has gone into understanding what drives precipitation in southern Africa and how ... -
Abiotic Stress Effects on Physiological, Agronomic and Molecular Parameters of 1-MCP Treated Cotton Plants
(2012-02-14)Abiotic stresses impact cotton (Gossypium hirsutum L.) affecting physiological, molecular, morphological, and agronomic parameters. One of the main yield components in cotton production is the number of bolls per unit ... -
Analysis of Spatial-Temporal Variations of Drought in Oklahoma
(2017-07-12)Drought is a recurrent natural hazard that has impacts on agriculture, hydrology, ecosystem, and social-economy. A comprehensive analysis of drought is valuable for drought assessment and mitigation. Oklahoma is a state ... -
BACTERIALLY MEDIATED WATER STRESS TOLERANCE IN WHEAT CONFERRED BY PHENAZINE-PRODUCING RHIZOBACTERIA
(2017-12-09)The plant microbiome is the community of microorganisms living in association with plants and are considered to be a “second genome,” capable of directly modifying the plant’s biotic and abiotic environment. Predicted ... -
Bayesian Modeling of Plant Drought Resistance Pathway
(2018-07-31)Plants are sessile organisms and are unable to relocate to favorable locations under extreme environmental conditions, and hence they have no choice but to acclimate and eventually adapt to the severe conditions to ensure ... -
Crop- and Location-Specific Drought Index for Agricultural Water Management: Development, Evaluation, and Forecasting
(2015-08-04)Severe droughts have plagued the United States over the last few years. The 2011 Texas drought, the 2012 U.S. drought, and the current California drought have greatly impacted the nation’s economy and agricultural production. ... -
Development of indices for agricultural drought monitoring using a spatially distributed hydrologic model
(Texas A&M University, 2005-11-01)Farming communities in the United States and around the world lose billions of dollars every year due to drought. Drought Indices such as the Palmer Drought Severity Index (PDSI) and Standardized Precipitation Index (SPI) ... -
Drought over the past century in Texas and New Mexico: reducing inhomogeneities in long-term climate records via statistical methods to study drought
(Texas A&M University, 2008-10-10)This research looks at the past century of Texas and New Mexico climate in order to create datasets sufficient for documenting climatic variations. Inhomogeneities in climate records are defined as variations in climatic ... -
Establishment and Management of Turfgrass Under Municipal Water Restrictions
(2015-12-07)Drought has become and continues to be a major concern throughout many areas of the United States. To better manage water supplies, municipalities are constantly in search of ways to conserve and ration water. In this ... -
INFAUNAL ABUNDANCE IN RESTORED AND REFERENCE MARSHES OF THE NORTHWESTERN GULF OF MEXICO: THE IMPACT OF HABITAT TYPE AND DROUGHT
(2012-05-04)To date, over 50% of historical tidal marsh habitat in the U.S. has been lost. A widely accepted approach to mitigate the loss of valuable ecological services is marsh restoration, which includes using excavated soil or ... -
Integrated Drought Modeling For Texas Under Climate Change Impact With Implications For Water Resources Planning
(2014-12-02)Drought is a deficiency in the hydro climatic variable of interest that is experienced for an extended period of time. In many parts of the world, it is a normal, recurring feature of climate and is therefore inevitable. ... -
Investigation of the utility of the vegetation condition index (VCI) as an indicator of drought
(2009-05-15)The relationship between the satellite-based Vegetation Condition Index (VCI) and frequently used agricultural drought indices like Palmer Drought Severity Index, Palmer’s Z-index, Standard Precipitation Index, percent ... -
Phenotyping Drought Tolerance in Cotton (Gossypium hirsutum, L.)
(2014-04-30)Cotton plant breeders need well-defined phenotypic parameters by which they can select drought tolerant lines as well as correlate phenotypes to allelic polymorphisms in the cotton genome. Soil-moisture availability is ... -
Physiological and genetic control of water stress tolerance in zoysiagrass
(Texas A&M University, 2006-04-12)Significant cultivar difference in many water stress responses of zoysiagrass (Zoysia japonica (Steud.) and Zoysia matrella (L.) Merr.) are shown in this study. Of the four cultivars, Palisades was the most water stress ... -
Quantitative Trait Locus (QTL) Mapping of Transpiration Efficiency Related to Pre-flower Drought Tolerance in Sorghum [Sorghum bicolor (L.) Moench]
(2012-07-16)There is an increasing need to improve crop water-use efficiency (WUE) (ratio of whole-plant biomass to cumulative transpiration) due to decreased water availability and increased food and energy demands throughout the ... -
Three Essays on Climate Variability, Water and Agricultural Production
(2014-07-23)Agricultural production and water resources are sensitive to climate variability and change. Decadal climate variability (DCV) is another force that has been found to influence crop yields and water supplies. DCV phenomena ... -
Warming and Intensified Summer Drought Influence Leaf Dark Respiration and Related Plant Traits in Three Dominant Species of the Southern Oak Savanna
(2011-08-08)The short-term temperature-response of dark respiration may be altered by climate warming through temperature acclimation; however the role of drought in influencing thermal acclimation is not known. We hypothesized that ...
