MAYFLIES (INSECTA) ABUNDANCE IN THE CUBA´S RIVERS YARA AND NAGUA: MICRO-HABITAT USE, SEASONALITY AND STREAM ORDER INFLUENCE
Analyzing the effect of altitude, river order and seasonality the authors have tried to establish those variables which defined micro-habitat use and abundance pattern of mayflies’ species in two rivers of the eastern region of Cuba: Nagua and Yara. This study was carried out during dry and rainy seasons. Lotic habitats (riffles) were sampled using two methods: direct picking-up out of stones, and D-net. Meanwhile, pool zones were sampled through four methods. In each predefined micro-habitat: direct picking-up out of stones, D-net in sand, Leave-packed, and Bank vegetation. To explore the abundance of the mayflies´ species by micro-habitats, a clustering k-means method was used. This analysis allows to cluster the samples in five groups according to the abundance by micro-habitats, altitude and stream order. There were found 12 331 individuals belonging to four families, 12 genus and 20 species. The results showed that the abundance of the mayflies have a strong influence by the microhabitats, seasonality and among rivers. Riffles was the microhabitats with more abundance of mayflies. This study provides important ecological information related with abundance patterns measured in the microhabitats, useful to monitoring programs.
