在过去十年中，一致的个体差异在(动物个性)和跨行为(行为综合症)行为中得到了很好的认识。然而，我们对这些现象背后的进化和发展机制的了解仍然不完整。在这里，我们探索了在野外捕获的成年欧洲绿色蜥蜴(Lacerta Viridis)及其2-3周大的实验室饲养的后代中，冒险和探索是否一致，并与不同的生态相关特征有关。成年和青少年都表现出动物个性，青少年的一致性更高。我们只在成年人中发现了冒险和探索(暗示有行为综合症)之间的相关性。青少年比成年人更具探索性。体型较大或无体外寄生虫的成年雄蜂比体型较小或寄生的雄蜂更具探索性。未成年的女性往往比男性更愿意冒险。父亲和他们的子女的行为没有相关性。我们得出结论，欧洲绿蜥蜴表现出高度的行为一致性，年龄是其强度的重要决定因素，并与可能影响健康的特征有关。(C)2014爱思唯尔B.V.保留所有权利。
Consistent individual differences within (animal personality) and across (behavioural syndrome) behaviours became well recognized during the past decade. Nevertheless, our knowledge about the evolutionary and developmental mechanisms behind the phenomena is still incomplete. Here, we explored if risk-taking and exploration were consistent and linked to different ecologically relevant traits in wild-caught adult male European green lizards (Lacerta viridis) and in their 2-3 weeks old laboratory-reared offspring. Both adults and juveniles displayed animal personality, consistency being higher in juveniles. We found correlation between risk-taking and exploration (suggestive of a behavioural syndrome) only in adults. Juveniles were more explorative than adults. Large or ectoparasite-free adult males were more explorative than small or parasitized males. Juvenile females tended to be more risk-taking than males. Behaviour of fathers and their offspring did not correlate. We conclude that European green lizards show high behavioural consistency and age is an important determinant of its strength and links to traits likely affecting fitness. (C) 2014 Elsevier B.V.
