Environmental Noise and Nonlinear Relaxation in Biological Systems

TL;DR

This paper investigates how environmental noise influences various biological systems, including insect mating, polymer translocation, and ecosystems, revealing complex nonlinear relaxation behaviors across these contexts.

Contribution

It provides a comparative analysis of environmental noise effects on diverse biological systems, highlighting nonlinear relaxation phenomena and introducing models for these interactions.

Findings

Environmental noise affects insect mating behavior.

Polymer translocation dynamics are altered by noise.

Ecosystem models show nonlinear relaxation under noise.

Abstract

We analyse the effects of environmental noise in three different biological systems: (i) mating behaviour of individuals of \emph{Nezara viridula} (L.) (Heteroptera Pentatomidae); (ii) polymer translocation in crowded solution; (iii) an ecosystem described by a Verhulst model with a multiplicative L\'{e}vy noise.
