Xiaonan Liu, Miaoxiao Wang, Yong Nie, Xiao-Lei Wu
Many organisms live in habitats with limited nutrients or space, competition for these resources is ubiquitous. Although spatial factors related to population’s manner of colonizing space influences its success in spatial competition, what these factors are and to what extent they influence the outcome remains…

Competition for space is ubiquitous in the ecology of both microorganisms and macro-organisms. We introduce a bacterial model system in which the factors influencing competition for space during colonization of an initially empty habitat can be tracked directly. Using fluorescence microscopy, we follow the fate of…

'Jaroslaw Krzywanski' 'Karolina Grabowska' 'Marcin Sosnowski' 'Dorian Skrobek'] Space exploration is a hot topic in the application field of mobile robots. Proposed solutions have included the frontier exploration algorithm, heuristic algorithms, and deep reinforcement learning. However, these methods cannot solve…

Spatial stochastic simulations of evolutionary processes are computationally expensive. Here, based on spatially explicit decoupling approximations (SEDA) introduced in [1], we derive a deterministic approximation to a spatial stochastic birth-death process in the presence of two types: the less advantageous resident…

'Kateryna Bazaka'] Title: Abstract Colonization of Mars: As humans gradually overcome technological challenges of deep space missions, the possibility of exploration and colonization of extraterrestrial outposts is being seriously considered by space agencies and commercial entities alike. But should we do it just…

Superorganisms such as social insect colonies are very successful relative to their non-social counterparts. Powerful emergent information processing capabilities would seem to contribute to their abundance, as they explore and exploit their environment collectively. In this series of three papers, we develop a…

Theories on the evolutionary origins of altruistic behavior have a long history and have become a canonical part of the theory of evolution. Nevertheless, the mechanisms that allow altruism to appear and persist are still incompletely understood. The spatial structure of populations is known to be an important…
