A stream physical habitat assessment in an urbanizing watershed of the Central U.S.A.
(University of Missouri--Columbia, 2015)
Longitudinal variations in aquatic biological habitat in a watershed (frequently associated with land-use in mixed-land-use watersheds) can be quantified by means of a physical habitat assessment (PHA). PHA indices include ...
An assessment of the whole tree weight, wood density, and specific gravity of four species groups in Washington County, Missouri
(University of Missouri--Columbia, 2015)
New methods of scaling logs by weight are becoming more prevalent in the Ozark forests of Missouri. In 2009, a major weather event known as a derecho downed millions of board feet of timber in Missouri and the ensuing ...
Bird data : Bolivia, La Paz
(Springer, 2010)
Urbanization alters ecosystems worldwide, but little is known about its effects in the Neotropical region. In the present research we examined the relative influence of different levels of urbanization and of some urban ...
Kinetic energy flux associated wiht natural and simulated rainfall events and instrumentation used in the evaluation
(University of Missouri--Columbia, 2011)
There have been many studies that focus on the evaluation of the raindrop-size distribution and the parameters that are based upon this distribution, ranging from radar reflectivity to kinetic energy flux at the surface. ...
Modeling the financial impact of management decisions on loblolly pine (Pinus taeda) production
(University of Missouri--Columbia, 2010)
Located primarily in the southeastern United States, Loblolly pine (Pinus taeda L.) is a variety of Southern yellow pine that is often planted by non-industrial private landowners seeking a beneficial long-term investment ...
Soil quality as affected by agroforestry and grass buffers in grazed pasture and row crop systems
(University of Missouri--Columbia, 2011)
Establishment of agroforestry and grass buffers within agroecosystems is believed to improve soil quality. Soil enzyme activities and water stable aggregates have been identified as sensitive soil quality indicators to ...
Bird data : Australia, Brisbane
(Thesis, University of Queensland, 2011)
Unprecedented loss of global biodiversity driven by anthropogenic actives continues, and in response governments and researchers around the world have prioritised efforts to slow the continued decline in species diversity. ...
Influence of residue management on soil chemical properties and nutrient flux in forests harvested for woody biomass
(University of Missouri--Columbia, 2014)
Altered soil solution chemistry and nutrient flux within forests harvested for woody biomass may result from disturbance, slash removals, slash decomposition, and mineralization. Because of the potential adverse effects ...
Bird data : Kenya, Nairobi
(Nairobi : Jomo Kenyatta University of Agriculture and Technology, Research Production and Extension Division, 2010)
The landscape structure of Nairobi city is experiencing rapid transformation as once wild and pristine spaces are converted to anthropocentric uses. In order to understand how the changing urban structure affects urban ...
Bird data : Canada, Ottawa
(Ottawa Breeding Bird Count, 2011)
We have only a basic understanding of how urban development affects native bird populations. Citizens, planners, and developers will all benefit from having access to rigorously collected and quantified baseline observations. ...
Bird data : Brazil, Porto Alegre
(Springer, 2011)
Cities are highly modified environments in which the only areas that resemble natural landscapes are urban parks with low human population density. Attempts are frequently made to maintain high bird diversity in cities for ...
Linking wetland management decisions to secretive marsh bird habitat use during spring migration and summer breeding on public wetlands in Missouri
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The extent to which secretive marsh birds rely on wetlands in Missouri during spring migration is relatively unknown. My objective for chapter one was ...
Linking wetland management decisions to secretive marsh bird habitat use during spring migration and summer breeding on public wetlands in Missouri
(University of Missouri--Columbia, 2015)
Dynamic occupancy modeling was used to determine how SMB occupancy and colonization and extinction probabilities were influenced by wetland management practices, including the duration and initiation date of spring water-level ...
Bird data : Switzerland, Lugano
(Wiley on behalf of the Ecological Society of America, 2010)
Spatially organized distribution patterns of species and communities are shaped by both autogenic processes (neutral mechanism theory) and exogenous processes (niche theory). In the latter, environmental variables that are ...
Bird data : Switzerland, Lucerne
(Wiley on behalf of the Ecological Society of America, 2010)
Spatially organized distribution patterns of species and communities are shaped by both autogenic processes (neutral mechanism theory) and exogenous processes (niche theory). In the latter, environmental variables that are ...
Bird data : Switzerland, Zurich
(Ecological Society of America, 2010)
Spatially organized distribution patterns of species and communities are shaped by both autogenic processes (neutral mechanism theory) and exogenous processes (niche theory). In the latter, environmental variables that are ...
Identification and characterization of atrazine-degrading phytochemicals in eastern gamagrass
(University of Missouri--Columbia, 2014)
Naturally occurring phytochemicals of the 1,4-benzoxazin-3-one (Bx) class exhibit broad chemical reactivity that includes detoxification of chloro-triazine herbicides. Atrazine (6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5- ...
