Hysteresis Can Grant Fitness in Stochastically Varying Environment
Although the existence of multiple stable phenotypes of living organisms enables random switching between phenotypes as well as non-random history dependent switching called hysteresis, only random switching has been considered in prior experimental and theoretical models of adaptation to variable environments. This work considers the possibility that hysteresis may also evolve together with ra...
متن کاملResponse of a deterministic epidemiological system to a stochastically varying environment.
Fluctuations in the natural environment introduce variability into the biological systems that exist within them. In this paper, we develop a model for the influence of random fluctuations in the environment on a simple epidemiological system. The model describes the infection of a dynamic host population by an environmentally sensitive pathogen and is based on the infection of sugar beet plant...
متن کاملThe Coalescent Process in a Population with Stochastically Varying Size
We study the genealogical structure of a population with stochastically fluctuating size. If such fluctuations, after suitable rescaling, can be approximated by a nice continuous-time process, we prove weak convergence in the Skorokhod topology of the scaled ancestral process to a stochastic time change of Kingman’s coalescent, the time change being given by an additive functional of the limiti...
متن کاملStability Analysis of Stochastically Varying Formations of Dynamic Agents
We analyze a network of dynamic agents where the topology of the network specifies the information flow between the agents. We present an analysis method for such a sjstem for both consensus and formation stabilization problems. To consider the general features introduced by the information flow topology, we consider the case of agent dynamics being a single integrator. Then we show that the me...
متن کاملAging in varying environment
An impact of environment on mortality rates is often modeled by a proportional hazards model. This model describes the memory-less property, when the mortality rate at a given instant of time depends only on current environment and does not depend on a history. In the presence of aging (degradation) this assumption is usually unrealistic and historydependent models should be considered. The sim...
