Fungi population variation under the Subtropical Ombrophilous Forest and Pinus taeda plantation

Abstract

This paper aims to evaluate vertical and horizontal distribution of fungi population in Subtropical Ombrophilous Forest and Pinus taeda plantation, separately. The experiment had been improved in the municipality of Tijucas do Sul, PR, with 2 factors and 3 replications. The evaluated factors were depth (litter, transition zone and soil) and seasons (winter and summer). The Subtropical Ombrophilous Forest toposequence was divided in plain, hillside and top, where it was placed a 10,000 m² plot; which was subdivided in one hundred subplots. It was selected five alleatory samples which composed the simple samples, and, as they were randomized, they composed one block sample unit. The P. taeda plantation exhibited a topographic sequence that was classified as plain, and the same topography was used for the following sampling. The microorganism’s population analyses revealed differences between depths, it was higher in the litter and in the summer. The fungi population presented no differences between seasons in the P. taeda plantation, it was higher in the litter. It was identified a higher fungi population in the Subtropical Ombrophilous Forest compared to the results observed in the plantation.
