Locomotor behavior of wolf spiders in the paramo

We ran locomotor behavior trials in which we tested the relative velocity of female wolf spiders of Pardosa sp. (Araneae: Lycosidae). Spiders were experimentally subjected to cold or heat conditions, and we measured their velocity afterward. A portion of those females was carrying an external egg sac that represented up to ~1/3 of their body size. This allowed us to test the effect of carrying that object on their speed. We conducted this fieldwork in the highland paramo environment of Costa Rica.本研究开展了运动行为试验，以测定豹蛛属（Pardosa sp.）雌性狼蛛的相对运动速度，该物种隶属于蛛形纲（Araneae）狼蛛科（Lycosidae）。实验中将受试蜘蛛分别置于低温或高温环境中，随后测定其运动速度。其中部分雌性个体携带有体外卵囊，卵囊体型最大可达其自身的约1/3，借此可探究携带该物体对其运动速度的影响。本研究的野外数据采集工作开展于哥斯达黎加的高原帕拉莫（paramo）生境中。
