Multi-Species Model of Stationary Biological Communities

Student: Viktor Zelenkov

Supervisor: Alexey Antonovich Nikitin

Faculty: Faculty of Computer Science

Educational Programme: Applied Mathematics and Information Science (Bachelor)

Year of Graduation: 2020

The main obstacle to the study of stationary biological communities, such as plants, is their lifespan that is too long compared to human. Biologists cannot research the communities for hundreds of years due to a shorter human lifespan. Nowadays they use computer simulations to accelerate the process. However, this method is too slow. To solve this problem Ulf Dieckmann and Richard Law have proposed to explore the system of integral-differential equations of spatial moments dynamics as an alternative to simulation. This paper continues the study of a system with three species. No previous study, as we know, has investigated such systems. First spatial moments have been used to compare the results of the numerical method with those obtained by simulations. The results are corresponded.
