Abstract

Morphologic alterations in the Cladocera population are crucial indicators of aquatic toxicity. This study describes deformities in Bosmina freyi sampled from three shallow urban reservoirs. Each reservoir was sampled monthly from May/2019 to April/2020. The specimens were separated and quantified, and the deformations on sensorial and swimming structures were photographed and drawn. Larger proportions of abnormal organisms were registered when the reservoirs had a high volume reduction and sediment resuspension.

城市小水库水蚤种群的形态异常(枝总目:水蚤科)

枝角类种群的形态学变化是水生毒性的重要指标。本研究描述了从三个浅层城市水库中取样的Bosmina freyi畸形。从2019年5月至2020年4月，每个水库每月进行一次采样。对标本进行分离和量化，并对感觉结构和游泳结构的变形进行拍照和绘制。当储层的体积减少和沉积物再悬浮率较高时，记录到更大比例的异常生物。
