报告摘要:The on-going disruption of ecological equilibrium in Siberia leads to the extinction of numerous wild and aboriginal species of domestic animals in the region. Aboriginal genepool is of great importance not only for biodiversity preservation but as a source of specific genetic resources to improve important economic traits of Siberian agricultural animals. The following animal breeds are being preserved and studied: Grey Ukrainian cattle, Yakutian cattle, Yakutian horse, Altai horse, Kulunda fur-cloak sheep, European bison, Altai snowcock. And the main purpose of our work is to demonstrate how mink has become a domesticate animal.Professor Trapezov proceeded from the development of specific estimates of domestic behavior in mink, using the “hand catch test”. Then starting populations includes individuals that were more tamable or more aggressive were established. As a result, two types of minks were distinguished, showing domestic or aggressive behavior.Do changes in brain biochemistry take place in the course of mink domestication? In minks showing aggressive response to human, the level of serotonin in the hypothalamus and corpus striatum was reduced in comparison with domestic minks. The higher level of brain serotonin in domestic animals can make them less aggressive.
