当在矩形竞技场中进行测试时，蚂蚁Gigantiops destructor的导航行为可以产生类似于脊椎动物的结果。这些结果通常被解释为支持动物分离空间几何形状和特征的能力。在这里，我们结合联合收割机的蚂蚁的路径与全景图像从蚂蚁的角度来看，可以作为一个基础上开发基于视图的匹配模型的详细分析。蚂蚁观察到的角落的选择更好地预测使用全景图沿着与一个简单的匹配过程[旋转图像差异函数（rIDF）]比模型假设隔离的几何形状和功能（G/F）。我们的基于视图的匹配模型也可以解释蚂蚁路径的某些方面（即，最初的方向，长度）的不同视觉条件下产生的，这表明蚂蚁使用这样的分类策略。在个体水平上分析，结果表明，蚂蚁的特异性路径往往是逐渐演变的，从试验到试验，揭示了蚂蚁在每次试验后，部分更新其路径记忆。这项研究说明了显着的灵活性，可以从使用类分类策略，并强调在脊椎动物中考虑它们的重要性。
When tested in rectangular arenas, the navigational behavior of the ant Gigantiops destructor can produce results similar to vertebrates. Such results are usually interpreted as supporting the ability of animals to segregate spatial geometry and features. Here, we combine a detailed analysis of ants' paths with panoramic images taken from the ant's perspective that can serve as a basis for developing view-based matching models. The corner choices observed in ants were better predicted by the use of panoramic views along with a simple matching process [rotational image difference function (rIDF)] than by models assuming segregation of geometry and features (G/F). Our view-based matching model could also explain some aspects of the ants' path (i.e., initial direction, length) resulting from the different visual conditions, suggesting that ants were using such a taxon-like strategy. Analyzed at the individual level, the results show that ants' idiosyncratic paths tend to evolve gradually from trial to trial, revealing that the ants were partially updating their route memory after each trial. This study illustrates the remarkable flexibilities that can arise from the use of taxon-like strategies and stresses the importance of considering them in vertebrates.
