|Biogeo-optics: particle optical properties and the partitioning of the spectral scattering coefficient of ocean waters
||We propose a direct method of partitioning the particulate spectral scattering coefficient of the marine hydrosol based on the concurrent determination of the concentrations of particulate mineral and organic matter (the total mass of optically activ...
|Bottom–up regulates top–down: the effects of hybridization of grass endophytes on an aphid herbivore and its generalist predator
||The ecological consequences of hybridization of microbial symbionts are largely unknown. We tested the hypothesis that hybridization of microbial symbionts of plants can negatively affect performance of herbivores and their natural enemies. In additi...
|Characters as Groups: A New Approach to Morphological Characters in Phylogenetic Analysis
||A new method for working with morphological characters is described and explored in experiments using human participants. The method uses direct comparison and sorting of images to produce hierarchical character-cladograms. A character-cladogram is a...
|Complex Data Produce Better Characters
||Abstract: Two studies were conducted to explore the use of complex data in character description and hybrid identification. In order to determine if complex data allow the production of better characters, eight groups of plant systematists were given...
|Determining Functional Relations in Multivariate Oceanographic Systems: Model II Multiple Linear Regression
||A method for estimating multivariate functional relationships between sets of measured oceanographic, meteorological, and other field data is presented. Model II regression is well known for describing functional relationships between two variables. ...
|Fitness Effects of Floral Plasticity and Thermoregulation in a Thermally Changing Environment
||To better understand the evolution of phenotypic plasticity and thermoregulation and their potential value for ectotherms in the face of global warming, we conducted field experiments to measure their effects on fitness and their association with rep...
|Floral Reflectance, Color, and Thermoregulation: What Really Explains Geographic Variation in Thermal Acclimation Ability of Ectotherms?
||Adaptive phenotypic plasticity in thermally sensitive
traits, that is, thermal acclimation, generally increases with increasing
latitude and altitude. The presumed explanation is that high-latitude/
altitude organisms have evolved greater acclimat...
|Necrotizing enterocolitis in preterm infants with patent ductus arteriosus: Does indomethacin increase the risk?
||Objectives: To examine any association of necrotizing enterocolitis (NEC) and intestinal perforation (IP) in very low birth weight neonates with indomethacin treatment, cumulative dose or maximum plasma concentrations. Methods: This is a retrospectiv...
|Simultaneous multiple comparisons with a control using median differences and permutation tests
||Permutation methods using median differences for simultaneous pairwise comparisons with a control are investigated. Simulation results suggest that the permutation methods are generally more powerful than the Dunnett procedure when data are from nonn...
|Step-Down Multiple Comparison Procedures Using Medians and Permutation Tests
||Richter and McCann (2007) presented a median-based multiple comparison procedure for assessing evidence of group location differences. The sampling distribution was based on the permutation distribution of the maximum median difference among all pair...
|Temperature-sensitive alternative oxidase protein content and its relationship to floral reflectance in natural Plantago lanceolata populations
||In many plant species, the alternative respiratory pathway consisting of alternative oxidase (AOX) is affected by growth temperature. The adaptive significance of this temperature-sensitivity is unresolved.
Here, leaf and spike (flower cluster) AOX...
|Using the Tukey–Kramer omnibus test in the Hayter–Fisher procedure
||Using Tukey–Kramer versus the ANOVA F-test as the omnibus test of the Hayter–Fisher procedure for comparing all pairs of normally distributed means, when sample sizes are unequal, is investigated. Simulation results suggest that using Tukey–Kramer le...
|Voiced initial consonant perception deficits in older listeners with hearing loss and good and poor word recognition.
||Purpose: This study examined differences in voiced consonant-vowel (CV) perception in older listeners with normal hearing and in 2 groups of older listeners with matched hearing losses: those with good and those with poor word recognition scores.
