character of agricultural vulnerability to changing climate in Missouri’s six climate divisions and the use of crop insurance by farmers as a climate adaptation or risk management strategy. Crop insurance plays an important role in the process of adapting...
Impacts of Precipitation, Land use Land cover and Soil type on the Water Balance of Lake Chad Basin
(2013)
the runoff from the agricultural land. The annual mean interception in LCB for the period 2003 - 2010 ranges from 0 - 63 mm with the mixed forest intercepting more water than open vegetation such as grass and shrub. Also the annual mean actual...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
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...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)

A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age ...
Effects of Weed-Resistance Concerns and Resistance-Management Practices on the Value of Roundup Ready[trademark] Crops
(AgBioForum, 2009)
This study estimates grower benefits of Roundup-Ready[trademark] (RR) weed management programs and how weed-resistance concerns and resistance-management practices affect those benefits. Direct survey methods were used to ...
The effect of reduced nocturnal temperatures on the performance of broiler chicks and hen turkey poults from 0 to 21 days of age
(University of Missouri--Columbia, 2018)
in the year 2016 (USDA, 2017a,b). The production of broilers in the United States has increased by 1% from 2015 and turkey production is up 5% from 2015 (USDA, 2017a). One could speculate that these production values will continue to increase...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
-and post-harvest samples showed that six of the twelve water quality parameters (TSS, TVSS, Ca, K, NO[superscript 3 -] and SRP) had probabilities that the post-harvest concentration would exceed the pre-harvest concentration, after taking climatic factors...
Visitor experiences at Eagle Days in Missouri
