Abstract

Predation can be an important factor shaping the dynamics of animal groups. The lizard Pholidoscelis fuscatus forms small groups while foraging, providing the opportunity to examine how predation risk influences group dynamics. We studied the escape angles of P. fuscatus during simulated predator approaches, focusing on whether grouped lizards behaved differently from solitary animals and the extent to which group cohesion was maintained during escape. Both solitary and grouped lizards exhibited non-random escape angles, oriented away from the approaching predator. However, lizards in groups exhibited escape angles closer to 0° (i.e., more directly away from the predator) than solitary lizards. Groups maintained their cohesiveness during flight. Grouping by P. fuscatus could allow more effective escape behaviour to occur.

独居动物和群蜥蜴的逃生角

捕食是影响动物群体动态的一个重要因素。蜥蜴Pholidoscelis fuscatus在觅食时形成小群体，为研究捕食风险如何影响群体动态提供了机会。我们研究了P. fuscatus在模拟捕食者接近时的逃跑角度，重点研究了成群蜥蜴的行为是否与独居动物不同，以及在逃跑过程中群体凝聚力的维持程度。独居蜥蜴和群居蜥蜴都表现出非随机的逃跑角度，远离接近的捕食者。然而，成群的蜥蜴比单独的蜥蜴表现出更接近0°的逃跑角度(即更直接地远离捕食者)。群体在飞行过程中保持了凝聚力。fuscatus的分组可以使更有效的逃脱行为发生。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
