The effect of different climatic conditions on the decomposition of wood by fungi and the interaction between fungal populations

Abstract

This article mainly explores the process of decomposing wood that simulates the fungal community. Under the conditions of a given environmental temperature and humidity, the relationship between the decomposition rate of the fungus and the growth rate, moisture resistance, environmental temperature and humidity of the fungus is obtained. In the Logstic model, a competitive resistance term was introduced to describe the interaction between fungal communities. In the end, we get: The interaction between communities will mainly make the community evolve in two directions: multiple populations coexist and a single species survives. Community evolution is more sensitive to changes in humidity, while changes in temperature have a significant impact on the decomposition rate of fungal communities.. And through the analysis of climatic conditions in different regions, it is obtained that the fungal community prefers warm and humid environments. The diversity of the population causes the fungus community to have stronger resistance and resilience. The slow growth rate of the fungus will make the community more adaptable, and it also leads to the reduction of the overall decomposition efficiency of the community.
