Abstract

As the key medium for decomposing wood fibers, fungi play a vital role in promoting the carbon cycle. The purpose of this paper is to establish mathematic models describing the process of fungi decomposing litter and wood fiber. The paper comprehensively consider the effects of temperature, moisture, location and other factors on fungal traits, and introduced the experimental data of the US Forest Service Center for Forest Mycology Research (CFMR).Based on the model of competition among populations and the modern coexistence theory, this paper establishes the competitive model between two fungi, then generalizes it to a variety of fungi and predicts the short-term and long-term effects.

Highlights

The carbon cycle is an important part of life on earth
The decomposition of plant materials and wood fibers is the key to this process
Yang Peng (2019) and others carried out the simulation of the birth and death process model of growth retardation

Summary

Introduction

The carbon cycle is an important part of life on earth Part of it includes the decomposition of compounds, allowing carbon to be renewed and used in other forms. The decomposition of plant materials and wood fibers is the key to this process. Some of the key factors that decompose wood fibers are fungi. Maynard (2019) and others believe that competition can profoundly affect biodiversity patterns by determining whether similar species are likely to coexist. By demonstrating that species richness can serve as a selfreinforcing buffer against competitive exclusion, these results help us understand how biodiversity is maintained in natural systems. Yang Peng (2019) and others carried out the simulation of the birth and death process model of growth retardation. The results showed that the growth rate of species gradually slowed down with the increase of population biomass after adding the retardation term.
