我们研究了跳蛛 Phidippus clarus（跳蛛科）的运动模式和导航信标的使用。克拉鲁斯菲迪普斯不会结网来捕获猎物，但会建造厚厚的丝质巢穴，用作夜间休息的场所。我们通过单独标记的蜘蛛和人造巢管网格来测量巢址的保真度。八月的雌性对地点最忠诚，其次是七月的雌性，然后是雄性。蜘蛛在结构复杂的栖息地中移动很长的距离，这表明巢穴在白天很可能在蜘蛛的视线之外，并且蜘蛛必须使用巢穴以外的线索来导航。然后我们测试了雌性是否使用信标来寻找它们的巢穴。在一项实验中，蜘蛛在与信标（橙色木销钉）相关或不相关的巢管上定居。然后他们在测试信标附近被释放。经历过信标的蜘蛛很容易接近自己的信标或不同位置的类似的、新颖的信标。相比之下，没有信标经验的蜘蛛接近测试信标的可能性明显较小。在第二次测试中，使用与自己颜色相同的新型信标进行测试的蜘蛛比使用不同颜色的新型信标进行测试的蜘蛛更有可能接近它。我们的结论是，克拉鲁斯虾可能需要导航技能，并且能够使用信标作为导航方法。跳蛛为导航和空间利用的研究提供了一种新的、易于处理的模型系统。 (c) 2005 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
We studied movement patterns and the use of navigational beacons in the jumping spider Phidippus clarus (Salticidae). Phidippus clarus does not build prey-capture webs, but does construct thick silken nests used as nighttime retreats. We measured the degree of nest site fidelity with individually marked spiders and a grid of artificial nest tubes. Females in August were most site-faithful, followed by July females and then by males. Spiders moved long distances through complexly structured habitats, suggesting that nests are likely to be out of sight of the spiders during the day, and that spiders must use cues other than their nest to navigate. We then tested whether females used beacons to find their nests. In one experiment, spiders colonized nest tube'S that were either associated with beacons (orange wooden dowels) or not. They were then released near a test beacon. Spiders experienced with beacons readily approached either their own beacon or a similar, novel beacon in a different location. In contrast, spiders with no experience with beacons were significantly less likely to approach the test beacon. In a second test, spiders tested with novel beacons of the same colour as their own were significantly more likely to approach it than were spiders tested with novel beacons of a different colour. We conclude that P. clarus are likely to need navigational skills and are able to use beacons as a method of navigation. Jumping spiders provide a new and tractable model system for the study of navigation and space use. (c) 2005 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.
