Description
A total of 201 individuals were recorded corresponding to three phyla: Arthropoda, Mollusca and Annelida. The most abundant phyllum was Arthropoda (85%), followed by Mollusca (15%) and the least abundant phyllum was Annelida. The most abundant invertebrates in the study area were insects with 164 individuals, with fewer gastropods with 30 individuals, 6 crustaceans and only one oligochaete. The most abundant insect families were Leptophlebiidae, Helicopsychidae and Veliidae corresponding to the orders Ephemeroptera, Tricoptera and Hemiptera respectively. The observed families of gastropods correspond to Thiaridae, Hydrobiidae and Planorbidae. In the case of crustaceans, two families, Pseudothelphusidae and Hyalellidae, were recorded. Oligochaetes were the least abundant organisms overall in this study with only 1 individual identified only at the class level. In terms of invasive species, Melanoides tuberculata and Hypolobocera guayaquilensis were recorded as intermediate host crayfish of Paragonimus mexicanus, which produces the paragonimiasis disease affecting the lungs of consumers that feed on this crayfish.

The Condor, Guitarra, Canoa, Quebrada 507, Pantano and Pigio streams located in Cerro Blanco were sampled. At each site, three replicates were made at the lower. The sampling sites were photographed to obtain a visual description of the study sites.

| Description du design | For sample collection, the D-net hand net with a 500 u mesh eye attached to an aluminium handle was used to capture organisms present in the water column, vegetation and boulders in inland waters; this net was used to sweep along the vegetated banks for 30 minutes in an area of approximately 10 m2. Vegetation and small stones were manually removed, allowing for the trapping of organisms attached to roots, stems, submerged leaves and those inhabiting under rocks, which allowed for qualitative analysis (Roldán 1988).
The samples were placed on a plastic tray and the macroinvertebrates were quickly extracted with tweezers and placed in 25 cc bottles, these were fixed with 80% alcohol; the remaining material was placed in zip lock bags and labelled, for later separation in the laboratory. Laboratory analysis In the laboratory, the organisms were washed and separated from the sediment, then the organisms were analysed, separated and identified to the level of major groups (Phylum) through stereomicroscopes and microscopes; these samples were transferred to 25 cc flasks and preserved with 80% alcohol. Only organisms that presented complete morphological structures were analysed for identification down to the lowest possible taxonomic level (genus or species), for which taxonomic keys specific to the region were used, such as: Holthuis (1952); Roldán (1988); Pennak (1989); Thorp J. P. Covich (1994); Ituarte (1995); Klemm (1995); Springer (2006); Domínguez (2009). Identified specimens were labelled and stored in 25 cc glass jars. |
