species of the water boatman (Corixidae; Sigara alternate. Trichocorixa nais. and Corisella), the 

 snails {PhyseHa. Gyraulm. and Stagnicola), mayflies {Caenis and Callihaetis). and beetles 

 (Oreodyles. Laccophilus. Hydroporus and Hygrotus). As the complexit\ of the pool habitat decreases 

 the dinger habitat species are lost, such as the damselllies and many of the water boatman taxa. Only 

 65% of the indicator species were present in this sample.
