Abiotic and biotic drivers of grassland structure: from individual to community responses
(2021-11-02)Climate has long been recognized as an important factor in determining the spatial-temporal distribution and abundance of species, consequently influencing global biological diversity. Model projections point to changes ... -
Can soil moisture sensors improve irrigation efficiency in southwest Oklahoma?
(Oklahoma State University, 2022-04-19)Farmers face numerous challenges when making water management decisions, and there is a need for research that develops a more thorough understanding of these considerations. This is especially true in Oklahoma, where ... -
Disentangling the relative contribution of land-atmosphere coupling toward the evolution of extreme events
(2021-05-14)The Great Plains region is characterized by highly variable and often extreme precipitation. Devastating multi-year droughts are common in the region, and can often be followed by years of above normal precipitation. Drought ... -
Drought-induced epigenetic modulation and transcriptional variation of winter wheat
(2020-12)The worsening climate uncertainty has exacerbated environmental stress, and the accompanying extreme weather disasters have damaged crop production across the globe. The yield production of wheat, one of the world's most ... -
Dying light: Detecting tree mortality risk with chlorophyll fluorescence
(Oklahoma State University, 2019-04-27)Increased greenhouse emissions have altered Earth's climate, resulting in rapid climate change which has brought warm droughts-especially in semi-arid regions-leading to forest die-off and dieback. Physiological stresses ... -
Effects of tree size and forest structure on forest dynamics
(2022-12)Climate change is exacerbating drought disturbances, reducing forest productivity, and causing increased forest mortality. Manipulating tree size and overall forest structure are two important components that are being ... -
Evaluation of turf-type bermudagrass cultivars and experimental genotypes for rooting characteristics and drought performance
(2021-07)Bermudagrass (Cynodon spp.) is one of the most widely used warm-season turfgrasses in the southern and transition zone areas of the United States. Due to the scarcity of water for turfgrass irrigation, it is necessary to ... -
Genome-wide analysis of drought stress induced histone 3 lysine 4 and histone 3 lysine 27 trimethylation modifications in winter wheat
(2020-07)Drought stress brings great impact on plant growth and development, that it is the most critical threat to world food security. Although drought responsive mechanisms plants have developed to tolerate drought stress are ... -
Long-term loblolly pine aboveground growth, canopy dynamics, and economic implications from throughfall exclusion, fertilization, and thinning in southeastern Oklahoma, USA
(2020-12)Loblolly pine (Pinus tadea L.) is the most commercially important timber species in the southern USA. Climate change induced drought, due to longer periods without rainfall, will alter forest growth in the region. Loblolly ... -
Monitoring and modeling soil salinity dynamics at greenhouse and field scales
(2018-12)An integrated monitoring and modeling approach was undertaken in greenhouse and field scale in terms of three main studies. In the first study, the changes in soil salinity and several other chemical properties were ... -
Plant Stress and Drivers in Ecosystem Sustainability
(Oklahoma State University, 2011-12-01)We sampled switchgrass ( Panicum virgatum L.) in adjacent fields near Medford, OK. Fields were either enrolled in CRP or were considered old field. Switchgrass in the CRP plots appeared to have a higher soluble protein ... -
Precipitation Whiplash Events Across the Southern Great Plains of the United States
(2021-08)The Southern Great Plains is a region that is prone to precipitation extremes and transitions between them which have direct impacts on agriculture, infrastructure, water quality and water quantity. However, current ... -
Small RNA profiles in soybean primary root tips under water deficit
(BioMed Central, 2016-12-05)Background: Soybean (Glycine max) production is significantly hampered by frequent droughts in many regions of the world including the United States. Identifying microRNA (miRNA)-controlled posttranscriptional gene regulation ... -
Temperature response surfaces for mortality risk of tree species with future drought
(IOP Publishing, 2017-11-17)Widespread, high levels of tree mortality, termed forest die-off, associated with drought and rising temperatures, are disrupting forests worldwide. Drought will likely become more frequent with climate change, but even ... -
Testing of Clonal Bermudagrass Cultivars and Experimental Genotypes for Differences in Drought Performance
(Oklahoma State University, 2010-12-01)Bermudagrass is used in many parts of the world as a forage crop and as turfgrass in sports fields, golf courses and lawns. Selection and identification of drought resistant bermudagrass cultivars under acute or chronic ... -
THE USE OF REMOTE SENSING AND EDDY COVARIANCE TECHNOLOGIES TO CHARACTERIZE CROPLAND, DROUGHT AND LAND MANAGEMENTS AND THEIR IMPACTS ON ECOSYSTEM DYNAMICS
(2017-05-12)With the increasing population, human needs more food, fresh water, and other ecosystem services, which burdens the agricultural and natural ecosystems. Under the background of climate change, meeting these human needs ... -
What kills trees? Drivers, mechanisms, and timing of climate-induced tree mortality
(2021-05)In recent decades, drought-induced tree mortality has been observed on every forested continent of the planet. This is of great concern, as trees support some of the most biodiverse communities on Earth, are keystones in ...
