The theory of games and microbe ecology

生态学理论解析微生物二分法

Ecology theory disentangles microbial dichotomies

本文通过将生态学理论与Monod曲线结合，把微生物的富营养/寡营养及快慢生长二分法统一为包含r/K策略者的生活史策略三角，为自然微生物群落研究提供了定量框架。

Biodiversity of marine microbes is safeguarded by phenotypic variability in ecological traits

Why, contrary to theoretical predictions, do marine microbe communities harbor tremendous phenotypic heterogeneity? How can so many marine microbe species competing in the same niche coexist? We discovered a unifying explanation for both phenomena by investigating a non-cooperative game that interpolates between individual-level competitions and species-level outcomes. We identified all equilibrium strategies of the game. These strategies are characterized by maximal phenotypic heterogeneity. They are also neutral towards each other in the sense that an unlimited number of species can co-exist…

有限的资源和进化学习可能有助于理解气候变化导致的鸟类不合时宜的繁殖

Limited resources and evolutionary learning may help to understand the mistimed reproduction in birds caused by climate change

我们提出了一个基于代理的模型的启发进化少数人博弈（EMG），虽然强烈适应的情况下，生态有限的资源竞争。经过一段时间后，这个游戏中的智能体能够预测进化驱动的学习过程的结果，即先验的最佳选择。我们表明，一个自我隔离的社会结构可以从这个过程中出现，即，极端学习策略总是受到青睐，而中间学习策略则趋于消亡。这一结果可能有助于理解生态和社会系统中的组织和合作行为的某些层次。我们使用这里报道的想法和结果来讨论生态学中当前感兴趣的一个问题：观察到某些鸟类产卵的错误时间，这是由于它们对气候变化的适应速度比它们的猎物慢。我们的模型支持这一假设，即特定于栖息地的限制可以解释为什么不同的人群适应不同的情况，在最近的实验中。

Multiple stable states in microbial communities explained by the stable marriage problem

Experimental studies of microbial communities routinely reveal that they have multiple stable states. While each of these states is generally resilient, certain perturbations such as antibiotics, probiotics and diet shifts, result in transitions to other states. Can we reliably both predict such stable states as well as direct and control transitions between them? Here we present a new conceptual model inspired by the stable marriage problem in game theory and economics in which microbial communities naturally exhibit multiple stable states, each state with a different species' abundance profi…

Fixation properties of rock-paper-scissors games in fluctuating populations

Rock-paper-scissors games metaphorically model cyclic dominance in ecology and microbiology. In a static environment, these models are characterized by fixation probabilities obeying two different "laws" in large and small well-mixed populations. Here, we investigate the evolution of these three-species models subject to a randomly switching carrying capacity modeling the endless change between states of resources scarcity and abundance. Focusing mainly on the zero-sum rock-paper-scissors game, equivalent to the cyclic Lotka-Volterra model, we study how the ${\it coupling}$ of demographic and …
