Abstract

Fungi plays an important role in the breakdown of wood, which is a part of carbon cycle. This kind of litter refers to plants that are no longer useful for humans to use. The aim of this paper is to model the decomposition process of wood fiber by fungi in the presence of multiple fungal interactions, different growth rates and niche width effects in a region. A set of differential equations are established to obtain the curve of the growth rate of fungal hyphae and the rate of wood decomposition increasing with time. Nextly, the Lotka Volterra model is adapted to established a model for the interaction of multiple kinds of fungi. Lastly, the effect of the diversity of fungal communities on the efficiency of decomposing wood is considered. It can be concluded that the greater the diversity of fungal communities, the greater the efficiency of the system in decomposition of wood.
