我们研究了气候和人类对从半落叶森林保护区采集的两种裸舌蜂的大小和波动不对称性的影响。每个物种收集了六十只雄性；对它们的翅膀进行了四次测量，以获得多变量尺寸指数和波动不对称指数。 Eulaema nigrita Lepeletier 的大小在地区和季节之间没有发现显着差异。在湿热季节收集体型较大的雄性 Euglossa pleosticta Dressler；然而，雄性的体型并不随地点而变化。降雨量的增加和随之而来的食物供应量的增加可能影响了 E. pleosticta 的大小增加。湿热季节在森林边界采集的蜜蜂比冷干季节采集的蜜蜂更加不对称；后者是在森林里发现的。这表明气候和人为干扰影响了E. pleosticta发育的稳定性。因此，该物种可以用作压力的生物指示剂。显然，E. nigrita 对环境干扰的抵抗力更强。
We examined the influence of climate and man on size and fluctuating asymmetry in two species of Euglossine bees collected from a semideciduous forest reserve. Sixty males of each species were collected; four measurements were made of their wings to obtain a multivariable size index and a fluctuating asymmetry index. No significant differences in the size of Eulaema nigrita Lepeletier were found between the areas and seasons. Larger males of Euglossa pleosticta Dressler were collected during the hot and wet season; however, male size did not vary with location. Higher rainfall and a consequent increase in food availability could have influenced the increase in size of E. pleosticta. Bees collected during the hot and wet season at the forest border were more asymmetric than bees collected during the cold and dry season; the latter were found inside the forest. This indicates that climate and anthropic interferences influence the stability of development of E. pleosticta. Consequently, this species could be used as a bioindicator of stress. Apparently, E. nigrita is more resistant to environmental interference.
