Decision-making ants An ant’s simple threshold for absolute nest-site quality determines whether a nest-seaching ant sticks with a potential nest site or continues searching. The poorer the quality, the more likely the ant is to switch to searching. I guess the probabilistic element comes from the variations in quality measurements inevitable when repeatedly assessing a noisy environment. Collectively, this enables a community to choose between a poor nest nearby and a good nest further away, without needing to comparatively evaluate both nests. Research done by Dr Elva Robinson and colleagues at Bristol’s School of Biological Sciences. More info here.
