| Summary: | The “paramo” provides essential environmental services to the population, being an ecological unit that regulates the water flows, and atmospheric carbon storage, which helps to control global warming. These ecosystems are suffering irreparable transformations that directly or indirectly control the structure of communities of microorganisms, which activity is essential for the maintenance of biogeochemical cycles. The diversity of heterotrophic and oligotrophic bacteria in horizons A, AB and B, of areas conserved and altered in the Páramo of Cortadera in the municipalities of Siachoque, Pesca and Toca were evaluated. The total number of aerobic heterotrophic and oligotrophic bacteria was estimated as colony forming units, being cultivated on Agar + Nystatin TSA Trypticase Soya Agar Scharlau®and Agar Agar MSC and MSH at 30°C for 48 hours respectively. The soils have a loamy clay texture, acid pH, low organic matter and high levels of P, isolating the genera Pseudomonas, Acinetobacter, Lactobacillus, Bacillus and Klebsiella, and oligotrophic bacteria genera Caulobacter, and Hyphomicrobium, being the most diverse the area Pesca. This diversity could be influenced by a wide range of biotic and abiotic factors, which can be affected by environmental changes and anthropogenic disturbances. |
