我们研究了阿根廷蚂蚁探索一个空旷的竞技场时形成的踪迹模式。利用一种新的成像和分析技术，我们估计了信息素在实验场所所有空间位置和不同时间的浓度。然后，我们通过观察信息素浓度与蚂蚁速度或方向变化之间的相关性，导出了个体蚂蚁对信息素浓度的响应函数。研究发现，蚂蚁会对当地信息素浓度做出反应，而它们的速度在很大程度上不受这些浓度的影响。随着时间的推移，蚂蚁并没有整合信息素的浓度，信息素在蚂蚁前面1厘米半径内的浓度决定了转弯的角度。发现对信息素的反应遵循韦伯定律，即蚂蚁两侧信息素的数量之差除以它们的总和决定了转弯角度的大小。这种比例响应与文献中用来模拟蚁群中二元桥实验结果的既定非线性选择函数明显矛盾（Deneubourg et al.1990)。然而，基于agent的模拟实现了韦伯定律响应函数，导致了踪迹的形成，并重现了文献中报道的结果。我们用解析的方法证明，当假定蚂蚁的首选运动方向周围有方向性噪声时，我们在实验中建立的个体对信息素浓度的韦伯型反应可以导出类似于集体决策的经典Deneubourg模型中的乙状结肠反应。

英文摘要：
We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in the experimental arena and at different times. Then we derived the response function of individual ants to pheromone concentrations by looking at correlations between concentrations and changes in speed or direction of the ants. Ants were found to turn in response to local pheromone concentrations, while their speed was largely unaffected by these concentrations. Ants did not integrate pheromone concentrations over time, with the concentration of pheromone in a 1 cm radius in front of the ant determining the turning angle. The response to pheromone was found to follow a Weber's Law, such that the difference between quantities of pheromone on the two sides of the ant divided by their sum determines the magnitude of the turning angle. This proportional response is in apparent contradiction with the well-established non-linear choice function used in the literature to model the results of binary bridge experiments in ant colonies (Deneubourg et al. 1990). However, agent based simulations implementing the Weber's Law response function led to the formation of trails and reproduced results reported in the literature. We show analytically that a sigmoidal response, analogous to that in the classical Deneubourg model for collective decision making, can be derived from the individual Weber-type response to pheromone concentrations that we have established in our experiments when directional noise around the preferred direction of movement of the ants is assumed.
