| 摘 要： | 研究了非自由生活的4窝11只猞猁幼仔的玩耍行为、亲和及入侵关系的变化.观察到36-57日龄幼仔的同胞打斗行为,这些打斗减少了这些幼仔之间游戏性接触的频次.这个"打斗期"与游戏行为和食性的变化同步发生.打斗后,幼仔游戏性接触的非对称性以及同胞之间的偏爱更加清楚.这些打斗导致了不同窝的幼仔之间等级结构的建立.

| Abstract: | The changes in play, affiliative and aggressive relations among lynx littermates were studied for 11 kittens from 4 different litters in captivity. Sibling fights were observed in these litters at the age of 36-57 days. The fights resulted in a decrease in the frequency of playful contacts in the litters. This "fight period" coincided with the intense development of playful behavior and dietary changes. The asymmetry of playful contacts and siblings' preferences were much clearer after the fights. These fights led to the establishment of a hierarchical dominance structure in the litters. |
