ABSTRACT

In this paper, we study the fungal community in which woody fibers are decomposed through fungal activity. Firstly, by analyzing the data of fungal traits, we establish Model I: a model for the decomposition of woody fibers by multiple fungi and their interaction. Secondly, under the existing microbiology research, we establish Model II: The Fungal Population Competition Model, to predict the relative advantages of species combinations in different environments and the importance and role of biodiversity. For this question, we extract the data of different fungi’s hyphal extension rate, moisture tolerance and decomposition rate. Then by modeling the Binary Nonlinear Regression model based on the least square method, we describe the breakdown of ground litter and woody fibers through two traits of fungi. Finally, we analyze the accuracy and sensitivity of the model, and prove that our model is accurate and stable for different parameters. Also, we discuss the latest developments in the role of fungi in ecosystems.
