Bird-mediated selection on fruit display traits in Celtis ehrenbergiana (Cannabaceae)
(Evolutionary Ecology Ltd, 2014-08)
Background: In mutualistic interactions of fleshy-fruited plants and seed-dispersing birds, dispersers act as natural selection agents on fruit display traits. Bird-mediated phenotypic selection on maternal and seed level ...
Comparison of selective genotyping strategies for prediction of breeding values in a population undergoing selection
(Amer Soc Animal Science, 2012-12-01)
Genomewide marker information can improve the reliability of breeding value predictions for young selection candidates in genomic selection. However, the cost of genotyping limits its use to elite animals, and how such ...
Level crossing rate and average fade duration for pure selection and threshold selection diversity-combining systems
(John Wiley & Sons LtdW SussexInglaterra, 2001)
Rapid method for determining very low fluoride concentrations using an ion-selective electrode
(1988)
A mathematical treatment is presented that allows the experimental determination of fluoride concentrations at the ng ml<sup>-1</sup> level with good precision. The proposed method is able to determine blank ...

Human genomic regions with exceptionally high levels of population differentiation identified from 911 whole-genome sequences
(BioMed Central, 2016-06-30)
Population differentiation has proved to be effective for identifying loci under geographically localized positive selection, and has the potential to identify loci subject to balancing selection. We have previously ...
Comparative Study on Feature Selection and Fusion Schemes for Emotion Recognition from Speech
The automatic analysis of speech to detect affective states may improve the way users interact with electronic devices. However, the analysis only at the acoustic level could be not enough to determine the emotion of a ...
Genetic variability and breeding potential of Flintisa Composite of maize in two levels of technology
(Brazilian Soc Plant Breeding, 2019-04-01)
The purpose this study was to verify the breeding potential of Flintisa Composite for low (LT) and high (HT) technology of cultivation, and the best selection strategy to be adopted. For this reason half-sib progenies were ...
The levels of selection debate: taking into account existing empirical evidence
(Universidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biología, 2016-09-01)
For over five decades the dominant neo-Darwinian view is that natural selection acts only at the genic and organismal levels, but the ignored empirical evidence of multilevel selection occurring in nature obtained over the ...
