Covariability of Vibrio cholerae Microdiversity and Environmental Parameters [PDF]

Applied and Environmental Microbiology, 2008
ABSTRACT Fine-scale diversity of natural bacterial assemblages has been attributed to neutral radiation because correspondence between bacterial phylogenetic signals in the natural environment and environmental parameters had not been detected. Evidence that such correspondence occurs is provided for Vibrio cholerae

Assessing Machine Learning-Based Prediction under Different Agricultural Practices for Digital Mapping of Soil Organic Carbon and Available Phosphorus

Agriculture, 2022
Predicting soil chemical properties such as soil organic carbon (SOC) and available phosphorus (Ava-P) content is critical in areas where different land uses exist. The distribution of SOC and Ava-P is influenced by both natural and anthropogenic factors.

Extending Finlay–Wilkinson regression with environmental covariates

Plant Breeding, 2023
Abstract Finlay–Wilkinson regression is a popular method for analysing genotype–environment interaction in series of plant breeding and variety trials. It involves a regression on the environmental mean, indexing the productivity of an environment, which is driven by a wide array of environmental factors.

SURVEILLANCE OF ENVIRONMENTAL DOSE RATE WITH THE COVARIANCE MATRIX

Radiation Protection Dosimetry, 2018
Abstract The objective of this study is the operational verification of an environmental dose rate monitoring network composed by several sensors. The verification of the study has been tested on the CIEMAT’s Radiological Network, establishing a records quality assurance of the detectors using the covariance matrix and the eigenvalues ...

Genetic and Environmental Covariation Between Autistic Traits and Behavioral Problems [PDF]

Twin Research and Human Genetics, 2007
AbstractOur objective was to examine the overlap between autistic traits and other behavioral problems in a general population sample, and explore the extent to which this overlap is due to genetic or environmental factors. Youth Self Report (YSR) data were collected in a general population sample of 424 twin pairs at 18 years of age, and their nontwin

Genetic and environmental influences on disgust proneness, contamination sensitivity, and their covariance [PDF]

Clinical Psychological Science, 2020
Dozens of studies indicate that individuals more prone to experiencing disgust have stronger symptoms of anxiety disorders – especially contamination sensitivity. However, no work has informed the degree to which this relationship arises from genetic versus environmental factors.

Weak Environmental Controls of Tropical Forest Canopy Height in the Guiana Shield

Remote Sensing, 2016
Canopy height is a key variable in tropical forest functioning and for regional carbon inventories. We investigate the spatial structure of the canopy height of a tropical forest, its relationship with environmental physical covariates, and the ...

Using Machine Learning Algorithms to Estimate Soil Organic Carbon Variability with Environmental Variables and Soil Nutrient Indicators in an Alluvial Soil

Land, 2020
Soil organic carbon (SOC) is an important indicator of soil quality and directly determines soil fertility. Hence, understanding its spatial distribution and controlling factors is necessary for efficient and sustainable soil nutrient management. In this

A review on digital mapping of soil carbon in cropland: progress, challenge, and prospect

Environmental Research Letters, 2022
Cropland soil carbon not only serves food security but also contributes to the stability of the terrestrial ecosystem carbon pool due to the strong interconnection with atmospheric carbon dioxide.
