论文摘要
疾病爆发会影响许多威胁性物种的生态系统，这些生态系统也与其他自然敌人作斗争。我们研究了一个$ 5 $的物种的环状游戏系统，该物种在流行病期间根据广义空间岩纸剪辑游戏的规则胜过其有机体。我们研究了行为运动策略的影响，这些策略使该物种中的一个人能够向疾病载体密度低和敌人的敌人高度浓缩的地区移动。我们执行一系列随机模拟，以发现自我保护策略在模式形成中的影响，从而计算物种的空间自相关功能。考虑到具有不同身体和认知能力的生物，我们计算了每种运动策略的好处，以降低选择和感染风险。我们的发现表明，如果将两种生存运动策略结合在一起，则可以在循环游戏中获得最大的利润，而个人优先考虑社会距离。在流行病引起症状性疾病的情况下，当生物识别和避免疾病向量时，感染风险下降不会导致该物种种群的增加，因为许多避难所被忽视，从而限制了保护自然敌人的益处。我们的结果可能有助于理解生态系统的行为策略，在这种生态系统中，有机体适应面对生活条件的变化。
Disease outbreaks affect many ecosystems threatening species that also fight against other natural enemies. We investigate a cyclic game system with $5$ species, whose organisms outcompete according to the rules of a generalised spatial rock-paper-scissors game, during an epidemic. We study the effects of behavioural movement strategies that allow individuals of one out of the species to move towards areas with a low density of disease vectors and a high concentration of enemies of their enemies. We perform a series of stochastic simulations to discover the impact of self-preservation strategies in pattern formation, calculating the species' spatial autocorrelation functions. Considering organisms with different physical and cognitive abilities, we compute the benefits of each movement tactic to reduce selection and infection risks. Our findings show that the maximum profit in terms of territorial dominance in the cyclic game is achieved if both survival movement strategies are combined, with individuals prioritising social distancing. In the case of an epidemic causing symptomatic illness, the drop in infection risk when organisms identify and avoid disease vectors does not render a rise in the species population because many refuges are disregarded, limiting the benefits of safeguarding against natural enemies. Our results may be helpful to the understanding of the behavioural strategies in ecosystems where organisms adapt to face living conditions changes.
