Species exclusion and coexistence in a noisy voter model with a competition-colonization tradeoff

Abstract: We introduce an asymmetric noisy voter model to study the joint effect of immigration and a competitiondispersal tradeoff in the dynamics of two species competing for space in regular lattices. Individuals of one species can invade a nearest-neighbor site in the lattice, while individuals of the other species are able to invade sites at any distance but are less competitive locally, i.e., they establish with a probability g 1. The model also accounts for immigration, modeled as an external noise that may spont… Show more

“…This result agrees with field observations showing that corridors have a positive impact on populations, aiding in their conservation. Future investigations should address the role of competition between species, e.g., predator-prey dynamics [27] and multispecies models [28,29], as well as the influence of patch arrangement on species richness and persistence [30,31,32,33].…”

“… 1 , 4 , 12 In general, the voter model can be viewed as a general model of competition, including competition between species in ecosystems, or between genotypes within a species during evolution. Despite this potential, the model has not been widely used in biology (see examples in ecology 9 , 13 16 and evolutionary biology 1 , 4 , 11 , 12 ). Its broader application is an exciting matter of future research.…”

“…The voter model has been extensively studied in many different fields, including physics (Sood and Redner, 2005), social dynamics (Castellano et al, 2009), and ecology (Martinez-Garcia et al, 2021). It is a valuable tool for exploring collective decision-making and opinion dynamics in large populations.…”
