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.
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：
Subterranean Biology is an international journal published by Pensoft on behalf of the International Society for Subterranean Biology [SIBIOS-ISSB] for the publication of original and significant contributions on all aspects of subterranean life. The Journal will consider original scientific papers dealing with any aspect of subterranean ecosystems and their components focusing on biology, ecology, evolution and conservation. Reviews and Commentaries: The journal welcomes review articles on aspects of subterranean biology. They should be submitted in the same way as research articles but use a simple layout with no more than three levels of headings. Commentaries on previous matter published in the journal may be also considered. Both reviews and commentaries will be reviewed. Book Reviews: Reviews of books, symposia volumes and conferences pertinent to the journal are welcome. The journal publishes electronic versions of the articles when these are ready to publish, without delays that might be caused by completion of an issue. These electronic versions are not "pre-prints" but final and immutable (Version of Record), hence available for the purposes of biological nomenclature. The date indicated on the electronic version is to be considered the actual publication date.
