土地利用变化影响物种丰富度和功能多样性。在巴西亚马逊，我们研究了油棕榈种植园对兰花蜜蜂（蜜蜂科：Euglossini）物种使用丰度和FD的影响。我们收集了雄性兰花蜂在油棕种植园（PALM），法律的保护区（LR），和河岸走廊（APP），然后我们用形态和生活史特征来描述每个物种。我们通过比较翅间跨度值来评估蜜蜂体型的差异。我们测试了栖息地的影响，兰花蜜蜂的分类和功能参数应用部分冗余分析（pRDA）。我们通过计算物种丰富度、功能丰富度和功能分散度来对比FD。我们在2015年和2016年的18个采样日内对30个物种的1176只蜜蜂进行了采样。来自PALM的雄蜂比LR地区的雄蜂大13.6%，来自APP的雄蜂与LR和PALM的雄蜂相比表现出相似的模式。不到15%的物种组成的变化与采样点之间的距离，8%是由于栖息地结构。在我们的pRDA中，空间差异解释了6%的兰花蜂性状的变化，但没有栖息地参数对FD的影响。随着油棕种植引起的土地利用变化，FD降低。我们的研究结果支持了许多蜜蜂受到耕地影响的观点。然而，LRs和APP之间的功能相似性反映了它们之间的共同结构元素，虽然我们没有发现我们评估的功能组成和栖息地结构之间的显着关系。
Land use change impact species richness and functional diversity (FD). In the Brazilian Amazon, we examined the impacts of oil palm plantations on orchid bee (Apidae: Euglossini) species using abundance and FD. We collected male orchid bees in oil palm plantation (PALM), legal reserves (LR), and riparian corridors (APP), and then we used morphological and life-history traits to characterize each species. We evaluated differences in bee body size by comparing intertegular span values. We tested the influence of habitat on taxonomic and functional parameters of orchid bees by applying a partial redundancy analysis (pRDA). We contrasted FD by calculating species richness, functional richness, and functional dispersion. We sampled 1176 bees from 30 species in 18 sampling days across 2015 and 2016. Males from PALM were 13.6% bigger than those in LR areas, and bees from APP showed a similar pattern compared to LR and PALM. Less than 15% of the variation in species composition was related to the distance among sampling sites, and 8% was due to habitat structure. In our pRDA, the spatial difference explained 6% of the variation in orchid bee traits, but there were no effects of habitat parameters upon FD. FD was reduced with land use change caused by oil palm plantations. Our findings support the belief that many bees are impacted by cultivated lands. Nevertheless, the functional similarity between LRs and APPs reflects common structural elements between them, although we did not find significant relationship between functional composition and habitat structure that we evaluated.
