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...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
.e. an aquatic-terrestrial zone (ATTZ), within the main channel of the lower Missouri River. Predictive models of sandbar morphometry (area, wetted perimeter, elevation, and water-surface slope) were developed to determine how changes in discharge affect...
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
on the 1) artificial regeneration of 13 native bottomland tree species, 2) composition of natural tree regeneration, and 3) composition, structure, and diversity of the resulting ground flora at three riparian sites in the Missouri Ozarks. Choice of tree...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
Over 500 million people live in proximity of an active volcano globally. Although lava flows rarely endanger human life, they often destroy critical infrastructure. Advancing our understanding of lava flow dynamics is ...

(University of Missouri--Columbia, 2019)
, and microbial community and structure; (2) compare ecosystem response to changing climatic conditions between Northern (Nebraska) and Southern (Texas) playa soils; and (3) assess effectsof increased agricultural nitrogen inputs on playa plant communities...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
and nutrient removal in a no-till, terrace-tiled field with and without CCs. Runoff water samples were collected using automated water samplers from individual runoff flumes and analyzed for total suspended solids (TSS), nitrate-N (NO3-N), dissolved reactive...
An empirical study of advertised retail meat prices in a metropolitan area
(University of Missouri--Columbia, 1975)
. Weekly data for the advertised meat prices from different firms were obtained for a total of thirteen (1960-72) years by consulting the appropriate newspaper files in the Missouri Historical Society Library. The primary objectives of this study were...
Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were conducted in 2005 and 2006...
Heterogeneity in body condition, survival, and seasonal origins among lesser snow and Ross's geese

Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
