Abstract

The surface morph of the Mexican tetra fish (Astyanax mexicanus) exhibits strong territoriality behavior and high levels of aggression. In contrast, the eyeless cave-adapted morph from Sierra de El Abra, México, rarely are aggressive and have totally lost the territorial behavior. These behaviors are part of what has been called the cavefish behavioral syndrome. Here, we report that several Astyanax cave populations of Sierra de Guatemala, unlike those reported for the Sierra de El Abra cave populations, display significant territoriality and aggression when confined into a reduced space. We discuss divergent evolutionary trajectories in terms of agonistic behavior for cavefish populations inhabiting different mountain ranges.

Astyanax岩洞鱼攻击性和领地性的不同进化途径

墨西哥四尾鱼（Astyanax mexicanus）的表面形态表现出强烈的领地行为和高度的攻击性。相比之下，墨西哥Sierra de El Abra的无眼洞穴变形很少具有攻击性，完全失去了领土行为。这些行为是所谓的穴居鱼行为综合征的一部分。在这里，我们报告了危地马拉山脉的几个Astyanax洞穴种群，与El Abra山脉洞穴种群不同，当被限制在狭小的空间内时，它们表现出显著的领土性和侵略性。我们讨论了栖息在不同山脉的洞穴鱼类种群在痛苦行为方面的不同进化轨迹。

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.
