兰花蜜蜂在不同的生物群系的采样提供了一个很好的机会来分析这一组的形态变异。我们研究了Eulaema nigrita的地理起源的确定的背景下，人口的形态变化。它还评估了这组在不同的景观从两个重要的生物群落，大西洋森林，巴西稀树草原，和它们之间的过渡带的人口变异。这些分析是通过记录形态分化的模式，使用几何形态测量分析的翅膀256个人，从9个地点，从4个不同的地貌。结果表明，从大西洋森林地貌的个体大于从稀树草原。个体的聚类是基于采样区的景观特征。结果表明，很少或甚至完全没有人口结构。总的来说，特定地点的人口分化并不强烈支持翅膀性状，加强声明符合更广泛的模式，兰花蜜蜂有很高的迁移能力。然而，这种细微的分化可能表明存在着由雌性亲合保持的局部适应性状或由环境因素引发的表型可塑性，尚待研究。
The sampling of orchid bees across different biomes provides an excellent opportunity to analyze morphological variability in this group. We examined the morphological variation of populations of Eulaema nigrita in the context of the determination of geographic origin. It also evaluated population variability of this group in different landscapes from two important biomes, Atlantic Forest, Brazilian Savanna, and the transition zone between them. These analyses were achieved by documenting the pattern of morphological differentiation using geometric morphometric analysis of the wings of 256 individuals, sampled from nine locations, from four different physiognomies. Results indicated that individuals from the Atlantic Forest physiognomies are larger than the ones from the Savanna. The clusterization of individuals was based on landscape features of the sampling areas. The results indicate little or even a complete absence of population structure. Overall, site-specific population differentiation is not strongly supported by wing traits, reinforcing the statement consistent with the broader pattern that orchid bees have a high migratory capacity. However, the subtle differentiation may indicate the existence of locally adapted traits kept by female philopatry or phenotypic plasticity triggered by environmental factors yet to be studied.
