Effects of dormant season soil flooding and soil temperature on pin oak (Quercus palustris) seedlings
(University of Missouri--Columbia, 2022)Bottomland forests are the dominant forest cover along the Mississippi Alluvial Valley. Changes in land use and hydrologic regimes have reduced the area of bottomland forest, putting pressure on the remaining area to meet ... -
Effects of light availability and herbivory on planted white oak (Quercus alba) seedlings and acorns
(University of Missouri--Columbia, 2022)Despite remaining abundant in the overstory across the eastern US, white oak (Quercus alba) is failing to regenerate in many forests. Many interacting factors contribute to the continued failure of white oak regeneration, ... -
Establishment of native plant species for livestock forage in silvopasture systems
(University of Missouri--Columbia, 2022)Incorporating sustainable agriculture practices and environmental stewardship into existing forage-livestock systems is growing in popularity. This project takes a novel approach incorporating native rather than introduced ... -
Estimating at-vessel mortality rates of shortfin mako sharks caught in the US pelagic longline fishery and examining environmental drivers of their depth use in the North Atlantic Ocean
(University of Missouri--Columbia, 2022)Shortfin mako sharks, Isurus oxyrinchus, have historically been a small part of recreational and commercial fisheries in the United States (U.S.). Recent stock assessments have identified declines in mako shark stocks that ... -
Genetic mapping of soybean cyst nematode resistance and evaluation of resistant germplasm in soybean and pennycress
(University of Missouri--Columbia, 2022)A single mode of genetic resistance derived from PI 88788 (rhg1-b) has dominated the $57.5 B US soybean market for almost three decades. The breakdown of resistance and selection of virulent nematode populations poses a ... -
The impact of economically important Grapevine viruses on yield and berry juice quality in the hybrid grape cultivars Norton and Chardonel
(University of Missouri--Columbia, 2022)Three grapevine viruses are considered to pose great threats to grape and wine production in the United States. Those viruses are Grapevine vein clearing virus (GVCV), Grapevine leafroll-associated virus 3 (GLRaV-3) and ... -
Increasing methionine content of soybean using CRISPR/Cas9 and developing machine learning predictive models
(University of Missouri--Columbia, 2022)Soybean [Glycine max (L.) Merr.] is an important protein source for both humans and animals. Its relatively low cost combined with its excellent nutritive value has enabled soybeans to attain elite stature as the world's ... -
Manipulating forest structure and ground flora composition for the restoration of oak woodlands and the reconstruction of oak savannas in Central Missouri
(University of Missouri--Columbia, 2022)Managers across the central US are interested in restoring once abundant ecosystems such as savannas and woodlands. These restorations are inundated with challenges like creating the appropriate native plant structure and ... -
The quantitative precipitation estimation (QPE) over Mid-Missouri and comparison between ground-truth point instruments and X- and S-band radars
(University of Missouri--Columbia, 2022)The estimation of rainfall rate from radar is crucial for hydrological modelling using remote sensing devices and ground truth instruments in the field of mainly atmospheric science and agriculture to prevent the loss of ... -
Turning up the heat: fire ecology and climate adaptive silviculture in longleaf pine forests
(University of Missouri--Columbia, 2022)Frequent fire is required to maintain the characteristic structure, function, and high biodiversity of longleaf pine woodlands. Longleaf pine regeneration is exposed to this frequent fire, yet persists as both patches and ... -
Uneven-aged management in the Missouri Ozarks: effects of site conditions, stand density, and prior populations on oak regeneration
(University of Missouri--Columbia, 2022)While studies have shown the importance of site characteristics and overstory density on the success of white oak regeneration under uneven-aged management, few studies have analyzed the effects of these variables over ... -
Using a vertical integration of Doppler-derived divergence to assess thunderstorm updraft/downdraft characteristics
(University of Missouri--Columbia, 2022)Analyses of thunderstorm updraft and downdraft characteristics, such as magnitude and size, can reveal essential information pertaining to the strength of the thunderstorm itself. Such information can aid in assessing the ...
