Pollinator service is essential for successful sexual reproduction and long‐term population persistence of animal‐pollinated plants, and innumerable studies have shown that insufficient service by pollinators results in impaired sexual reproduction (“pollen limitation”). Studies directly addressing the predictors of variation in pollinator service across species or habitats remain comparatively scarce, which limits our understanding of the primary causes of natural variation in pollen limitation. This paper evaluates the importance of pollination‐related features, evolutionary history, and environment as predictors of pollinator service in a large sample of plant species from undisturbed montane habitats in southeastern Spain. Quantitative data on pollinator visitation were obtained for 191 insect‐pollinated species belonging to 142 genera in 43 families, and the predictive values of simple floral traits (perianth type, class of pollinator visitation unit, and visitation unit dry mass), phylogeny, and habitat type were assessed. A total of 24,866 pollinator censuses accounting for 5,414,856 flower‐minutes of observation were conducted on 510 different dates. Flowering patch and single flower visitation probabilities by all pollinators combined were significantly predicted by the combined effects of perianth type (open vs. restricted), class of visitation unit (single flower vs. flower packet), mass of visitation unit, phylogenetic relationships, and habitat type. Pollinator composition at insect order level varied extensively among plant species, largely reflecting the contrasting visitation responses of Coleoptera, Diptera, Hymenoptera, and Lepidoptera to variation in floral traits. Pollinator composition had a strong phylogenetic component, and the distribution of phylogenetic autocorrelation hotspots of visitation rates across the plant phylogeny differed widely among insect orders. Habitat type was a key predictor of pollinator composition, as major insect orders exhibited decoupled variation across habitat types in visitation rates. Comprehensive pollinator sampling of a regional plant community has shown that pollinator visitation and composition can be parsimoniously predicted by a combination of simple floral features, habitat type, and evolutionary history. Ambitious community‐level studies can help to formulate novel hypotheses and questions, shed fresh light on long‐standing controversies in pollination research (e.g., “pollination syndromes”), and identify methodological cautions that should be considered in pollination community studies dealing with small, phylogenetically biased plant species samples.

花卉特征，生境和系统发育是传粉媒介服务的预测因子：植物群落的观点

授粉媒介服务对于成功的有性繁殖和动物授粉植物的长期种群持续生存至关重要，无数研究表明，授粉媒介服务不足会导致有性繁殖受损（“花粉限制”）。直接解决跨物种或生境的传粉媒介服务变化的预测因素的研究仍然相对较少，这限制了我们对花粉限制自然变化的主要原因的理解。本文评估了与传粉有关的特征，进化史和环境作为传粉媒介服务预测指标的重要性，这些传粉指标来自西班牙东南部未受干扰的山地生境的大量植物物种中的传粉媒介服务。获得了43个科中142属的191种昆虫授粉物种的传粉媒介访视的定量数据，以及简单的花性状（花被类型，传粉媒介访视单位的类别和探视单位干重），系统发生和生境的预测值类型进行了评估。在510个不同的日期进行了总共24,866例传粉媒介普查，占观察到5,414,856分钟的花朵。花粉类型（开放与限制），探视单位类别（单花与花包），探视单位质量，系统发育关系和栖息地类型。昆虫顺序水平上的授粉媒介组成在植物物种中差异很大，很大程度上反映了鞘翅目，双翅目，膜翅目和鳞翅目对花性状变化的不同访视响应。传粉媒介的组成具有很强的系统发育成分，并且在整个植物系统发育中，访视率的系统发生自相关热点的分布在昆虫阶之间也有很大差异。栖息地类型是传粉媒介组成的关键预测因子，因为主要昆虫种群的栖息率在生境类型之间表现出解耦的变化。区域植物群落的综合授粉媒介抽样显示，可以通过简单的花艺特征，栖息地类型和进化史的组合来简约地预测授粉媒介的来访和组成。雄心勃勃的社区级研究可以帮助提出新颖的假设和问题，
