Data from: Are pollination "syndromes" predictive? Asian dalechampia fit neotropical models

Using pollination-syndrome parameters and pollinator correlations with floral phenotype from the neotropics, we predicted that Dalechampia bidentata Blume (Euphorbiaceae) in southern China would be pollinated by female resin-collecting bees between 12 and 20 mm in length. Observations in southwestern Yunnan Province, China, revealed pollination by resin-collecting, female Megachile (Callomegachile) nr. faceta Bingham (Hymenoptera: Megachilidae). These bees, at 14 mm in length, were in the predicted size range, confirming the utility of syndromes and models developed in distant regions. Phenotypic-selection analyses and estimation of adaptive surfaces and adaptive accuracies together suggest that the blossoms of D. bidentata are well adapted to pollination by their most common floral visitors.本研究借助新热带区（neotropics）的传粉综合征（pollination syndrome）参数及传粉者与花部表型（floral phenotype）的关联特征，预测中国南方的二齿香大戟（Dalechampia bidentata Blume，大戟科Euphorbiaceae）将由体长12~20 mm的雌性树脂采集蜂（resin-collecting bees）传粉。 在中国云南省西南部开展的野外观测显示，其实际传粉者为雌性切叶蜂属（Megachile）丽切叶蜂亚属（Callomegachile）近缘Bingham命名的faceta切叶蜂（Megachile nr. faceta Bingham，膜翅目Hymenoptera：切叶蜂科Megachilidae）。该蜂体长14 mm，处于本研究预测的体长范围之内，证实了在异域区域建立的传粉综合征及相关模型的实用性。 表型选择分析（phenotypic-selection analyses）、适应曲面（adaptive surface）与适应精度（adaptive accuracies）的联合估算结果表明，二齿香大戟的花部结构已高度适配其最常见的花部访客的传粉行为。
