Abstract

The purpose of this study was to examine macrofungal community richness at different distances from the Quebrada Máquina in the cloud forest of Monteverde, Costa Rica. Twenty transects no closer than ten meters apart were tested. Each transect contained a 1X 1 m2 plot positioned at zero, five, ten, fifteen, and twenty meters from the stream edge. Fungi were counted and photographed and weather and substrate type were recorded. I predicted to find more macrofungal richness closer to the river because of water and sunlight availability. However, using Friedman’s method for randomized blocks, I found a Chi squared value of 9.18 (df = 4, p > 0.05), which shows no statistical significance in fungal community richness between the five different distances. However, graphing mean number of species found per distance, we can see a trend. It shows that fungal richness is highest at the middle distances. I also tested distribution of species on substrates, and found dead wood was the most common. A Chi squared Goodness of Fit Test (assuming substrate abundance was equal) showed that the distribution differed significantly from the expected distribution (Chi squared = 315.5, df = 5, p < 0.001). These results therefore imply that there may be more dead wood at the middle distances than at the closest and farthest distances, or that other conditions are more favorable to fungi there. El propósito de este estudio fue examinar la riqueza de la comunidad de Macrohongos a diferentes distancias de la Quebrada Máquina en el bosque nuboso de Monteverde, Costa Rica.
