The morphological variations of four populations of geographically isolated located in the area of inter-Andean valleys and Chaco of Chuquisaca, Bolivia, were evaluated. Fifty-three females and sixty-one males were collected in the peri-domicile and analyzed with geometric morphometrics tools to study the patterns of the head and wing shape variation. The principal component analysis and canonical variate analysis revealed morphological variations between the populations studied, which were then confirmed by the permutation test of the differences between populations using Mahalanobis and Procustes distances. The multivariate regression analysis shows that the centroid size influences the shape of the heads and wings. of the inter-Andean valleys are longer in the head and wings compared to the population of the Chaco. We propose that the geometric shape variation may be explained by geographical changes in climatic conditions, peri-domiciliar habitats, food source quality, and the use of insecticides.
对位于玻利维亚丘基萨卡的安第斯山谷间和查科地区四个地理隔离种群的形态变异进行了评估。在住所周边收集了53只雌性和61只雄性样本，并用几何形态测量工具进行分析，以研究头部和翅膀形状的变异模式。主成分分析和典型变量分析揭示了所研究种群之间的形态变异，然后通过使用马氏距离和普氏距离的种群间差异置换检验得到证实。多元回归分析表明，质心大小会影响头部和翅膀的形状。与查科种群相比，安第斯山谷间种群的头部和翅膀更长。我们认为，几何形状变异可能是由气候条件、住所周边栖息地、食物源质量和杀虫剂使用的地理变化所导致的。
