Abstract

Agonistic and non-agonistic behaviors were studied before, during, and after the formation of social status in crayfish. Differences in the expression of a non-agonistic behavior by dominant and subordinate crayfish developed in parallel with the differences in agonistic behaviors that indicate the animals' social status. An increase in burrowing behavior marked the ascendancy of the dominant animal, while an immediate suppression of burrowing paralleled the inhibition of aggressive behavior in the new subordinate. The strikingly similar changes in both agonistic and non-agonistic behaviors following the decision on status suggest related underlying neural mechanisms.

摘要

在小龙虾形成社会地位之前、期间和之后，对其争斗行为和非争斗行为进行了研究。优势小龙虾和从属小龙虾在非争斗行为表达上的差异，与表明动物社会地位的争斗行为差异同步发展。掘洞行为的增加标志着优势动物的崛起，而掘洞行为的立即抑制则与新从属动物攻击行为的抑制同步。在确定地位后，争斗行为和非争斗行为都发生了惊人的相似变化，这表明存在相关的潜在神经机制。
