不同地位的克氏原螯虾各自在镜面环境中的反应
Behavioral Response of Crayfish of Different Status to a Reflective Environment Respectively
摘要
Abstract
For the study of crayfish dominant and subordinate's behavior differences in the mirror reflection environ?ment and the influence of mirror for the winner-effect and loser-effect. This study separate every pair of crayfish(domi?nate and subordinate according to the pre-experiment)and rest for 1 d,then insert mirror in their own tank,observe their behavioral responses for 30 min. The results show that the dominant and subordinate all choose to avoid reflection envi?ronment(P<0.05),suggesting that the crayfish have the ability to recognize the mirror-image and make significant behav?ioral responses,and both prefer non-reflective environment;but subordinate behave more action than the dominant in the reflective corner(P<0.05),indicating that subordinate maybe more sensitive than dominate when facing a"intruder"alone in their own field. Based on the results,this study also compares the change of the dominance index(DI)of the dom?inant and subordinate crayfish which have respectively lived on the mirror environment for 7 d,discuss whether the mir?ror environment regulate winner and loser effect. The result shows that the mirror has an effect to lower the winner effect of the dominant and the failure effect of the subordinate,meaning that narrow the gap of social status.关键词
