Development of shy/bold behaviour in southern dumpling squid (Euprymna tasmanica)

Behavioural syndromes are important in the context of understanding the evolution of behaviour. This study examines the lifetime development of shy/bold behaviour of dumpling squid (Euprymna tasmanica). The first component examined correlations of shy/bold behaviour across two test contexts - a threat and a feeding test, measured 5 times during the lifetime of the squid. The second component examined developmental plasticity in shy/bold phenotypes with age and sexual maturity.

行为综合征（behavioural syndromes）对于解析行为演化过程至关重要。本研究针对饺子乌贼（Euprymna tasmanica）的害羞/大胆行为（shy/bold behaviour）的终生发育模式展开探究。研究包含两个部分：第一部分分析了害羞/大胆行为在两种测试情境——胁迫测试与摄食测试——中的跨情境相关性，该系列测量在乌贼的终生周期内共开展5次；第二部分则探究了害羞/大胆行为表型（phenotypes）的发育可塑性（developmental plasticity）随年龄与性成熟进程的变化规律。
