MORENO RODRIGUEZ, Fabián; CARO CARO, Clara Ines; PINILLA, Gabriel Antonio  e  OSORIO, Diana Paola. Current Knowledge Status on Periphyton Algae and Benthic Macroinvertebrates of The Meta Region, Colombia. Acta biol.Colomb. [online]. 2017, vol.22, n.3, pp.274-306.

Nowadays the Meta Department has a high hydrological potential, which results in an opportunity for agriculture and livestock. Moreover, activities of the oil industry have significantly increased, which have brought new challenges and threats to the region. Consequently, different types of discharges and environment modifications affect the Meta Region's rivers in their watersheds and their riparian and benthic communities. However, these systems are poorly understood, including the periphyton and macroinvertebrate communities that inhabit them. In this paper, we provide a review of the most relevant characteristics of these communities, and we discuss the changes caused by human activities on the ecological stability of the rivers in a regional context. Additionally, we presented a list of periphytic algae and benthic macroinvertebrates taxa registered in the Meta Region.
