Conversely, natural selection resulting from pollinator limitation in small isolated or low‐density populations is suggested to cause rare, isolated species to favor autogamy (42; 18; 38; 43; 79). In high‐density populations, pollinators tend to be more species‐constant and are more likely to carry appropriate pollen .
