Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the effects of prescribed...
A study of the factors influencing the ability of the animal to digest its food
(University of Missouri--Columbia, 1916)
The purpose of the digestion trials, to be discussed in this paper, was to determine the effect of various factors on the ability of the animal to digest its food. The object of these experiments is somewhat different from the great majority...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
Disturbance-mediated oak (Quercus spp.) woodlands were formerly a prevalent community type in Missouri, and their restoration is a key objective of land management agencies and conservation organizations. Over one-third of wooded land in Missouri (2...

Structure and organization comparisons of U.S. large volume swine producers : a national survey
(University of Missouri--Columbia, 1986)
A national sample of hog operations marketing 1,000 head or more a year was taken in 1981. A mail questionnaire gathered the necessary information. A second survey grouped operations into three groups: feeder pig producers, ...
Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)
/water-quality stations were installed in a nested-scale watershed study design to capture differing land-use type influences on SSC. Mean SSCs were estimated to be 66.0, 70.0, and 86.0 [mu]l/l for the headwater (agricultural), suburban (mixed land-use), and urban sub...
Evaluating effects of neonicotinoid seed treatments and agroecosystem land management practices on solitary bees in Midwestern agroecosystems
(University of Missouri--Columbia, 2021)
Bees are declining due to multiple factors including habitat loss and non-target exposure to pesticides resulting from agricultural intensification. Solitary bees are often overlooked as important pollinators, but they are valuable contributors...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
-fortran (HSPF) was used to estimate the hydrology and sediment loading throughout the Brush Creek, MO watershed for future land use development scenarios between upstream and downstream locations. Brush Creek does not have a proper monitoring station...
Agroforestry and cover crops for improving surface water and groundwater quality
(University of Missouri--Columbia, 2023)
Unsustainable agricultural practices and the rapid expansion of agricultural lands to satisfy the food demand of the growing world population have caused significant sediment, and nutrient losses from agricultural fields, harming the environment...
Detection and modeling of bat species occupancy at multiple scales across a forested landscape in southeastern Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Populations of forest dwelling bats have been in decline in recent years, and have therefore become increasing foci in forestry research efforts. Difficulty in bat species...

Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
