ANALYSIS OF SPATIAL GENETIC VARIATION REVEALS GENETIC DIVERGENCE AMONG POPULATIONS OF PRIMULA VERIS ASSOCIATED TO CONTRASTING HABITATS

Abstract Genetic divergence by environment is a process whereby selection causes the formation of gene flow barriers between populations adapting to contrasting environments and is often considered to be the onset of speciation.Nevertheless, the extent to which genetic differentiation by environment on small spatial scales can be detected by means

A self-designed oxygen-kerosene ablation system SALTY DOG was employed to study the ablation mechanism and performance of the carbon-carbon composites.Particle concentrations of the gas-solid two-phase ablation flow were 0, 1.37%, 2.22%, and 2.64% respectively.The microstructure of post-test samples was analysed through the scanning electron micros
