Best Management Practice Use and Efficacy for the Virginia Nursery and Greenhouse Industry
… efficiency, and also serve to help meet clean water limitations on contaminants entering waters such as the Chesapeake Bay Watershed. Research is lacking on which BMPs are most widely used or most efficacious for Virginia nursery and greenhouse growers. Objectives of this work were to determine …

Deep-Layer Terrestrial Hydrologic Memory and Mechanisms of Its Influence on the Eco-Climatology of the Biosphere
… land surface models. Moreover, plants in water-limited environments use a mechanism called ""hydraulic redistribution"" for transferring moisture via the root system from moist soil layers to dry soil layers. Analyses using observed and simulated datasets of soil moisture indicate an …

Sensitivity of northern red oak (Quercus rubra L.) to variation of temperature and moisture availability along latitudinal and longitudinal climate gradients
… a species. These models assume that temperature limitations control the latitudinal range boundaries for tree species in the eastern United States, and that water limitations control the western range boundary. This study investigated spatial variation of tree-growth responses to historical …

Overcompensation of Ipomopsis aggregata following ungulate herbivory: getting to the root of it
… the compensatory response, particularly under water limited conditions, increasing compensation from equal to over. In a year of normal precipitation, a fungicide treatment reduced the compensatory response from overcompensation to a marginally significant trend toward overcompensation, by …

Irrigation and nitrogen management of soybean in highly productive soils
… practices. Two areas of interest include water limitations of soybean yield under rainfed conditions in highly productive Illinois soils and use of fertilizer nitrogen (N) to supplement soybean when mineralized soil N and biologically fixed N may be insufficient. Three studies on …

Resin-based method for concentration of enteric viruses and F-RNA coliphages from water samples
Fecal contamination of source and recreational waters represents a public health concern due to potential content of human pathogens, and the variety of sources from which an individual may be exposed to such contamination. Enteric viruses such as noroviruses, rotaviruses, adenoviruses and …

High-throughput phenotyping and physiological genetics of stomatal patterning and water use efficiency in maize
… of maize has shown to be associated with greater water inputs, which makes maize production more sensitive and vulnerable to drought events. In addition, the greater atmospheric vapor pressure deficit in the future climate will pose greater forces to pull water vapor out of plants. Thus, there is …

Effects of Climate, Forest Structure, Soil Water, & Scale on Biosphere-Atmosphere Gas Exchange in a Great Lakes Mixed-Deciduous Forest
… exercises to test the sensitivity of carbon, water, and momentum transfer to climate, canopy structure heterogeneity, soil moisture heterogeneity, time, and scale within a Great Lakes Mixed-Deciduous Forest located at the University of Michigan Biological Station (UMBS).We first described a …

Green water and loading on high speed containerships
Green water problem and its loading effects on high speed containerships was investigated with the purpose of developing a modelling framework that can practically guide naval architects to a better understanding of this problem and improvements in design. The research began by reviewing extensive …

The functional role of root-associated microbiome and metabolome of myrothamnus flabellifolia
… dynamics of these interactions under severe water limitations have not been comprehensively investigated. Consequently, a primary objective of this study was to unravel the beneficial root-associated microbiome of M. flabellifolia and delineate their functions in the context of water deficit …
