Understanding the evolution of cooperation is an important topic in several areas of science, such as economics, politics, negotiations and agreements on climate change, biology, and many other areas. In biology, the cooperation between individuals of different species, called mutualism, involves ecological interactions such as pollination, protection from natural enemies, and trophic and sheltering interactions as mycorrhizae. Different species, here understood as different populations, evolve in response to selective pressures imposed by individuals of the same population over themselves, but also as a result of interactions with individuals from other populations. The symbiosis is a mutualistic interaction in which the partners became intrinsically (physically or physiologically) integrated. Many of this special type of mutualism comprise interactions between haploid and diploid organisms that reproduce sexually and asexually, respectively. Furthermore, the haploid species of these interactions are usually organisms with restricted locomotion at reproduction when compared with the diploid partner. Cheating the partner to obtain the profits of the interaction, but not giving anything in return, is a rare behavior in symbiosis. In this project, I propose to model the evolution of symbiosis taking into account the different reproduction methods and ploidies of the partners. I also intend to research how the spatial distribution of individuals with different ploidies and reproduction methods can affect the mutualism evolution as well as how fixation is reached. (AU)
