Abstract This paper deals with the complex dynamical behavior of a discrete-time two-prey one-predator system with Holling Type-III functional response, coupled with inter-specific competition among the prey due to dietary overlap and intra-specific competition among the predators. The existence and local stability criteria of the steady states of the system are analyzed and the conditions for permanent co-existence of the three species are obtained. Finally, using a suitable example, some numerical simulations are performed to illustrate the rich dynamics of the system. [ABSTRACT FROM AUTHOR]

The article discusses the use of computer software in ecology research. According to the author, ecologists are using artificial intelligence (AI) to understand complex interactions among a variety of species. Topics include how ecologists are using AI to predict which invasive plant species are most likely to spread and the challenges to using AI techniques in ecology research, such as the requirement of large amounts of data.

The article discusses a 2014 report in the journal "PLoS Biology" about the creation of a computer model, named Madingley, that obeys the same basic principles as life on planet Earth by Drew Purves and colleagues at software company Microsoft's Computational Science Laboratory in Cambridge, England. How Purves and colleagues programmed Madingley to simulate the way all types of organisms interact on a global scale is discusses at length.
