In this work, we consider a reaction–diffusion system, modeling the interaction between nutrients, phytoplankton, and zooplankton. Using a semigroup approach in urn:x-wiley:00222526:media:sapm12345:sapm12345-math-0001, we prove global existence, uniqueness, and positivity of the solutions. The nonlinearity is handled by providing estimates in urn:x-wiley:00222526:media:sapm12345:sapm12345-math-0002, allowing to deal with most of the functional responses that describe predator/prey interactions (Holling I, II, III, Ivlev) in ecology. The paper finally exhibits some time asymptotic properties of the solutions.

浮游生物群落反应扩散模型的适度性,正性和时间渐近性,涉及具有奇异性的理性非线性

在这项工作中,我们考虑一个反应扩散系统,对营养物,浮游植物和浮游动物之间的相互作用进行建模。使用中的半群方法缸:x-wiley:00222526:media:sapm12345:sapm12345-math-0001,我们证明了解的全局存在性,唯一性和正性。通过提供中的估计值缸:x-wiley:00222526:media:sapm12345:sapm12345-math-0002来处理非线性,从而可以处理描述生态系统中捕食者/猎物相互作用(Holling I,II,III,Ivlev)的大多数功能响应。本文最后展示了该溶液的一些时间渐近性质。
