Abstract
Wood-inhabiting fungi are responsible for the degradation of dead wood, playing a role in nutrient cycling and nutrient transport making them indispensable to their ecosystem’s health. Fungi are generally understudied, specifically in the tropics despite its proven hotspot in diversity and the importance of conservation. Wood-inhabiting fungi were investigated in the eastern Andean montane cloud forest of Ecuador to determine the biodiversity, distribution, and relation to an altitudinal gradient. Along multiple ridges of EcoMinga’s Rio Zuñac reserve, 13 20x20 meter (0.1-hectare) quadrants between the altitudes of 1300 to 2000 meters were sampled for wood-inhabiting fungi. A total of 175 samples were taken comprised of 36 families and 152 species demonstrating extremely high diversity and low species coverage. Species abundance estimations suggest a much higher quantity of species in the Ecuadorian montane cloud forest than are currently described. Six different altitudes were compared, and it was found that, on a spectrum, communities were neither distinct nor the same provoking the need for more study on the complete effect of altitude and different biotic and abiotic factors.
Resumen
Los hongos que habitan en la madera son responsables de la descomposición de los troncos, siendo la base en el ciclo de nutrientes, además son indispensable para el desarrollo del ecosistema. Generalmente los hongos son poco estudiados, especialmente en los trópicos, donde existe una alta biodiversidad de especies y que se debería prestar más atención sobre la importancia y conservación. La investigación sobre los hongos se realizó en el bosque nublado, en una zona comprendida entre la población de Baños y Puyo, al oriente del Ecuador, para biodiversidad, distribución y tendencia existente en esta zona. La muestra se produjo en la reserva del Rio Zuñac, donde la altura del lugar oscila entre los 1300 a 2000 msnm. Dentro de la investigación se determinaron 13 cuadrantes de 20x20 meteros (0.1 ha) dentro de ellos se encontraron 152 especies de 36 diferentes familias en 175 muestras colectados. A pesar de haberse encontrado una alta cantidad de especies, esta muestra representa un bajo porcentaje de la cobertura de especies existentes en la zona. En la investigación se tomó en cuenta seis diferentes altitudes para comparar las comunidades de hongos. Se encontró que las comunidades no fueron lo mismo ni distinta.
