We tested the importance of microenvironmental topographic parameters as predictors of emmer wheat genetic variation using three classes of single-locus (or at most several-loci) genetic markers (allozymes, glutenins, and qualitative traits) and two classes of markers of polygenic inheritance (phenological and morphological traits). Canonical correspondence analysis (CCA) and redundancy analysi...

The Southern Ocean plays a major role in the Earth’s climate, provides fisheries products and help maintenance of biodiversity. degree correspondence between physical biogeochemical spatial variability regionalization were investigated by calculating main factors that statistically explained within 48.1 zone Commission for Conservation Antarctic Marine Living Resources (CCAMLR). mean value vari...

The study uses 30 years of the third generation Advanced Very-High-Resolution Radiometer (AVHRR) NDVI3g monthly data from 1982 to 2012 identify natural clusters and important driving factors upstream watersheds in Taiwan through hierarchical cluster analysis (HCA) redundancy (RDA), respectively. Subsequently, as a result HCA, six were identified based on NDVI data, delineating unique characteri...

INTRODUCTION The aim of the study was to analyse genetic architecture of RA by utilizing multiparametric statistical methods such as linear discriminant analysis (LDA) and redundancy analysis (RDA). METHODS A total of 1393 volunteers, 499 patients with RA and 894 healthy controls were included in the study. The presence of shared epitope (SE) in HLA-DRB1 and 11 SNPs (PTPN22 C/T (rs2476601), S...

Ammonia-oxidizing archaea (AOA) have been reported at high abundance in much of the global ocean, even in environments, such as pelagic oxygen minimum zones (OMZs), where conditions seem unlikely to support aerobic ammonium oxidation. Due to the lack of information on any potential alternative metabolism of AOA, the AOA community composition might be expected to differ between oxic and anoxic e...

The Edwards Aquifer and related Edwards-Trinity of Central Texas, USA, is a global hotspot stygobiont biodiversity. We summarize 125 years biological investigation at the San Marcos Artesian Well (SMAW), best studied most biodiverse groundwater site (55 taxa: 39 described 16 undescribed) within Groundwater Ecosystem. Cluster analysis redundancy (RDA) incorporating temporally derived, distance-b...

This paper studies Regularized Discriminant Analysis (RDA) in the context of face recognition. We check RDA sensitivity to different photometric preprocessing methods and compare its performance to other classifiers. Our study shows that RDA is better able to extract the relevant discriminatory information from training data than the other classifiers tested, thus obtaining a lower error rate. ...

We present a generalized multivariate seismic event identification method, Regularized Discrimination Analysis (RDA) [Friedman 1989], that can be applied to a large number of regional discriminants. RDA is readily adaptable to an outlier or classical identification approach to regional seismic identification. RDA is designed to address the problems associated with linear (LDA) and quadratic (QD...

Understanding the capacity of forest tree species to adapt climate change is increasing importance for managing genetic resources. Through a genomics approach, we modelled spatial variation in adaptation within Australian temperate Eucalyptus globulus, identified putative drivers this genomic variation, and predicted locations future refugia populations at-risk maladaptation. Using 812,158 SNPs...

ABSTRACT To determine the presence of emergent contaminants in aquatic environments and to evaluate responses dominant taxa benthic macrofauna, seven stations were sampled along three rivers that serve as public water suppliers sampling campaigns, Upper Iguassu Basin, Brazil. Concentrations ethinylestradiol, fenofibrate, ibuprofen triclosan detected sediment. correlate patterns distribution abu...
