Modelling combat strategies in fungal mycelia

Area of Science:

• Mycology
• Mathematical Biology
• Ecology

Background:

• Fungal mycelia are crucial for nutrient cycling, biological control, and land remediation.
• Competition among fungal communities significantly impacts biodiversity and biotechnological applications.
• Understanding fungal interactions is key to optimizing ecological and industrial uses.

Purpose of the Study:

• To simulate and analyze the combat dynamics between two fungal colonies using a mathematical model.
• To identify key factors influencing the outcome of fungal interspecific competition.
• To explore the emergence of non-transitive hierarchies and defensive structures in fungal communities.

Main Methods:

• Development of a mathematical model representing fungal mycelia as partial differential equations.
• Numerical integration of the model equations to simulate fungal growth and combat.
• Analysis of simulation results to determine the influence of various parameters on combat outcomes.

Main Results:

• The model accurately simulates known outcomes of fungal combat.
• Combat success is determined by hyphal suppression, biomass degradation, and nutrient resource utilization.
• Non-transitive hierarchies and specialized defensive structures emerge under specific resource redistribution conditions.

Conclusions:

• Mathematical modeling provides valuable insights into fungal competition dynamics.
• Fungal interactions are complex, influenced by resource availability and inter-colony interactions.
• The study's findings can inform strategies for biological control and ecological restoration.
