Physiological traits for screening drought resistance in barley
Evaluates critically a number of physiological traits which may be related to drought resistance in cereals and examines the feasibility of using these screening techniques in selecting more drought resistant genotypes of barley for South Australia

PARENT SELECTION IN TOMATO BASED ON MORPHO-PHYSIOLOGICAL TRAITS
… if a relationship exists between selected morpho-physiological traits and general combining ability for yield in determinate and indeterminate tomato inbred lines, to determine if a relationship exists between these traits and the average probability that an inbred can produce transgressive …

Intersection of environment, behavior, and physiological traits on angling vulnerability
… the removal of fish with specific heritable traits. The mechanism(s) defining why fish strike lures are unknown, as are how environmental factors influence capture, leaving knowledge gaps surrounding selection effects of capture and harvest. Objectives included how physiological and …

Defining the ecological and physiological traits of phytoplankton across marine ecosystems
… and bioinformatic pipelines to characterize the physiological response of phytoplankton to their environment at various levels of taxonomic grouping. An in silico Bayesian statistical approach was designed to identify stable reference genes from high-throughput sequence data for use in RT-qPCR …

Genetics of Physiological Traits Associated with Drought Tolerance in Soybean (Glycine max)
… production is often limited by drought stress. Physiological traits from exotic germplasm that confer drought tolerance may be useful in improving commercial soybean production. For example, carbon isotope ratio (δ13C) is positively correlated with water use efficiency (WUE), and nitrogen …

Physiological Traits and Quantitative Trait Loci Associated with Nitrogen Use Efficiency in Soft Red Winter Wheat
… NUE was associated with above-ground biomass at physiological maturity were found to be both highly heritable across multiple N supplies. In the second study, two bi-parental mapping populations having a common low ('Yorktown') and two high (VA05W-151 and VA09W-52) NUE parents were characterized …

Genes, haplotypes and physiological traits associated with a chromosome 3B locus for wheat improvement in hot climates
… in a Mexican environment-type. To study the physiological mechanisms under qYDH.3BL control, we developed heterozygous inbred families (HIF). The lines were phenotyped in the deep soil platform. The lines with the RAC875 allele among the HIFs increased biomass, single grain weight and number …

Evaluation of physiological traits and identification of QTLs for drought tolerance in hexaploid wheat (Triticum aestivum L.).
… study comprised three major parts: a comparative physiological study of drought responses under controlled conditions; a genetic study to construct the skeleton map of a doubled haploid (DH) population; and a quantitative trait loci (QTL) analysis to identify QTLs associated with drought tolerance …

Identification and Characterization of Physiological Traits Related to Productivity of Maize (Multiple Regression, Leaf Senescence, Inheritance, Green Score)
… concentrate research efforts the most important traits related to productivity. Our objectives were to: (a) evaluate genotypic variation and the relationship of a large array of physiological traits to maize (Zea mays L.) grain yield and stalk lodging in a group of 76 hybrids; (b) utilize …

Inheritance of reactions to gray leaf spot and maize dwarf mosaic virus in maize and their associations with physiological traits
Gray leaf spot, caused by Cercospora zeae-maydis, can be a yield-limiting factor in maize where continuous minimum tillage practices are followed. Commercial corn hybrids were evaluated for response to gray leaf spot for seven years at two Virginia locations (Shenandoah and Wythe Counties) and one …

Studies on the Metabolism and Senescence of Nodulating and Nonnodulating Isolines of Soybean (Glycine Max L. Merrill Cv. Harosoy)
… similarly. A secondary objective was to compare physiological traits of nodulated and nonnodulated plants relative to productivity.

Combining remotely sensed estimates of structure and function to improve quantification of forest productivity
… ecosystems, integrating both structural and physiological information. This work includes three separate studies under a common objective to establish an improved understanding of forest productivity in different forest compositions using a combination of physiological function from optical …

The energetics of sociality in the molerats (Bathyergidae)
… the factors selecting for the characteristic physiological traits of subterranean rodents. It also isolates the the probable causes of eusociality within the molerats (Bathyergidae). The bathyergids display the widest range of sociality of all mammals, from strictly solitary genera …

Why it takes all kinds: diversity mechanisms and patterns in ecological communities
… mean-field model is used to show that the traits of individuals in a community affect community diversity. The mathematical analysis, supported by numerical simulations, demonstrates that trade-offs between the individual traits are required for community diversity to exist. Moreover, the …

Gut physiology and host-microbe interactions of the rotation-resistant variant of the western corn rootworm (Diabrotica virgifera virgifera LeConte) (Coleoptera: Chrysomelidae)
… In search of explanations for the distinct physiological traits and gene expression profiles documented in RR-WCR populations, host-microbe interactions in adult RR- and WT-WCR guts were characterized and tested for their contribution to WCR gut physiology (Chapter 2). Microbial community …

Analysis and synthesis of iris images
Of all the physiological traits of the human body that help in personal identification, the iris is probably the most robust and accurate. Although numerous iris recognition algorithms have been proposed, the underlying processes that define the texture of irises have not been extensively studied. …
