Effect of Population Reduction on mtDNA Diversity and Demographic History of Korean Cattle Populations
Cattle Mitochondrial DNA Genetic Diversity Population Expansion
2016/5/10
The population sizes of three Korean indigenous cattle populations have been drastically reduced over the past decades. In this study, we examined the extent to which reduction in populations influenc...

Excellent outcrops in Matale Sri Lanka provide unique insight into the emplacement and evolution history of hydrothermal and pegmatitic rocks in the central highlands of Sri Lanka. Field, structural, ...
Chemical history of molecules in circumstellar disks
astrochemistry – stars: formation – circumstellar matter – planetary systems: pro- toplanetary disks – molecular processes
2011/10/8
The chemical composition of a protoplanetary disk is determined not only by in situ chemical processes during the disk phase, but also by the history of the gas and dust before it accreted from the na...
Star formation history, double degenerates and type Ia supernovae in the thin disc
stars: white dwarfs − stars: evolution − stars: binaries: close − supernovae: general − Galaxy: evolution − Galaxy: structure
2011/9/27
We investigate the relation between the star formation history and the evolution of the double-degenerate (DD) population in the thin disc of the Galaxy, which we assume to have formed 10 Gyr before t...
