- Abstract
Introduction: Macroinvertebrates are an important biological component of aquatic ecosystems as they are actively linked in the flow of matter and energy. Objective: To identify the Functional Feeding Groups (FFG) of benthic macroinvertebrates present in Caño Baranda. Materials and method: Physical and chemical characteristics were measured in 5 sampling points along Caño Baranda during the rainy season, likewise aquatic macroinvertebrates were collected using Surber net, Tienneman net, Kick net and hand collection. Samples were obtained at each sampling point to estimate the density of macroinvertebrates and FFG per taxa. Results: 251 organisms belonging to 32 families were collected, sorted into 9 orders. The most abundant families were Leptophlebiidae (35%) and Glossosomatidae (12%). Collected organisms were associated to five FFG, the dominant being collectors (45%) followed by predators (23%) which presented positive correlations with pH. On the other hand, the least collected group was shredders (1%) whose presence was related to the increase in dissolved oxygen.
