✦ Synopsis


In the two desert reservoirs examined seasonal and spatial variations in both densities and biomasses of chironomid dipterans and tubiticid oligochaetes were quite high, but mean values are comparatively low. Densities of both organisms were generally low in summer, larger in autumn, and highest in spring. Disjunct distribution of the two taxa was evident. Distribution of these animals with depth in these desert reservoirs is affected by hypolimnic oxygen depletion, food supply (Chlorophyll-a concentrations), lake morphology and perhaps by substrate composition and predator-prey interactions.
