测定了内布拉斯加州一系列温带生境的花外蜜腺植物的丰度。花外蜜腺植物的平均盖度在河岸林下为1.3%，原始落叶林下为1.8%，高草草原为0.0%，沙丘草原为8.3%。沙丘草原花外蜜腺植物群落分布明显，平均盖度不同，蜜腺活动呈季节性变化。将花外蜜腺植物的盖度与蚂蚁丰度、植物物种多样性、降雨量和无霜期进行比较，发现前两者与花外蜜腺的平均盖度呈极显著相关。
The abundance of plants with extrafloral nectaries was determined for a series of temperate habitats in Nebraska. Mean cover of plants with extrafloral nectaries was 1.3% in riparian forest understory, 1.8% in virgin deciduous forest understory, 0.0% in tall-grass prairie, and 8.3% in sandhill prairie. Sandhills prairie contained distinct communities with different mean cover of plants with extrafloral nectaries and showed seasonal changes in nectary activity. Cover of plants with extrafloral nectaries was compared to ant abundance, plant species diversity, rainfall and frost-free season: the first two showed highly significant correlations with mean cover of extrafloral nectaries.
