AQUATIC MACROINVERTEBRATES FROM HIDROLOGICAL SYSTEM IN A NATURAL PROTECTED AREA IN CENTRAL MEXICO
In Natural Protected Areas (NPA) in Mexico, flora and vertebrates are well studied; however, aquatic macroinvertebrates (AM) are scarcely known, especially in Sierra Gorda (Central México). The aim of this study was to describe the AM diversity and their relationship with water quality along five streams in two periods (dry and rainy). AM were collected using multi-habitat method (kick net 500 µm), water samples and physicochemical characteristics were taken. Samples were processed to obtain 23 variables. Invertebrate’s diversity indexes and cumulative curves were assessed. An ANOSIM analysis were tested from a matrix (environmental and AM taxa). Analysis were performed with R software. A total of 93 families from 103 possible (Chao 1) were identified along the streams studied. Families, Chironomidae, Baetidae and Elmidae were the most abundant. Sites from streams Extoraz and Santa Maria showed unique assemblages of AM. According with water characteristics and AM diversity, Ayutla stream showed statistical differences with other studied streams (ANOSIM, P= 0.001). Sierra Gorda possess a great diversity of AM, Ayutla stream has the highest diversity, representing a Sanctuary for diversity, meanwhile other studied streams were considered a diversity buffer in the NPA.
