摘要

侧化是动物的特征之一,在无脊椎动物和脊椎动物中都有发生。侧化存在于个体水平和群体水平两个层面。本研究的重点是在实验室条件下欧洲绿蜥蜴(Lacerta viridis)的个体和种群水平的偏侧化。实验中观察到蜥蜴在没有视觉控制的情况下,在一个改进的t型迷宫中出现了偏侧化。蜥蜴被一个来自尾端的活塞刺激,以模拟捕食者从后面攻击。评估左、右选项的数量。统计分析证实,在个体和群体水平上,侧化没有统计学上的显著差异。自我切割的缺失或存在表明,与左倾或右倾的个体相比,无偏见的蜥蜴有更好的机会从捕食者手中逃脱。在我们所研究的L. viridis种群中,似乎没有偏见可能是在捕食者攻击中生存的最佳策略。

Lateralization at the individual and population levels of European green lizard in Slovak Karst

Lateralization is one of the specific characteristics of animals, occurring in both invertebrates and vertebrates. Lateralization exists at two levels, individual level and population level. This research is focused on the individual- and population-level lateralization of the European green lizard (Lacerta viridis) under laboratory conditions. Lateralization was observed experimentally in a modified T-maze without the possibility of visual control by lizards. Lizards were stimulated by a piston from the caudal side to simulate a predator attack from behind. The numbers of left and right choices were evaluated. Statistical analysis confirmed no statistically significant difference in lateralization at both the individual and population levels. The absence or presence of autotomy suggests that non-biased lizards have a better chance of escape from a predator than left- or right-biased individuals. In the population of L. viridis studied by us, it seems that to be non-biased could be the best strategy to survive predator attacks.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
