Evolution of sexual dichromatism: contribution of carotenoid- versus melananin-based coloration

In birds, carotenoid-based plumage coloration is more dependent on physical condition and foraging abilities and less constrained developmentally than is melanin-based coloration. Thus, female mate choice for honest signals should result in more intense sexual selection on carotenoidthan on melanin-based plumage coloration. Using variation in sexual dimorphism as an indirect measure of the inte...

Evolutionary Biology Select

Next to natural selection, sexual selection is the most powerful force driving evolution. A cluster of recent papers about sex and evolution are the focus of this Select. New work suggests that the evolution of sex chromosomes is a potent mechanism for resolving sexual conflict and for driving speciation. Furthermore, another study suggests that the mechanism by which the sex of the offspring o...

Phylogenetic Analysis of bor Gene in an Escherichia coli Strain 1378 (O78:K80) Isolated from an Avian Colibacillosis Case in Tehran, Iran

Colibacillosis is known as a fatal bacterial disease resulting in a high level of commercial loss worldwide. This study amid to elucidate the sequence, genetic characteristics, and phylogeny of the bor gene in Escherichia coli (E. coli) strain c1378 (O78:K80) isolated from avian colibacillosis in Iran and develop a rapid and optimal polymerase chain reaction (PCR) mol...

Diagnosis of the disease using an ant colony gene selection method based on information gain ratio using fuzzy rough sets

With the advancement of metagenome data mining science has become focused on microarrays. Microarrays are datasets with a large number of genes that are usually irrelevant to the output class; hence, the process of gene selection or feature selection is essential. So, it follows that you can remove redundant genes and increase the speed and accuracy of classification. After applying the gene se...
