项目摘要
Cushing Competition is one of the most fundamental interactions occurringamong biological species. The investigators study carefully derived modelsin order to understand the mathematical and biological mechanisms thatpromote the stage-structure-mediated coexistence phenomenon that occursunder strong inter-specific competition. Special cases that allow adimensional reduction are particularly important in the study because thesecases are amenable to rigorous mathematical analysis using stability theoryand bifurcation methods. The robustness of the competitive coexistencephenomenon is investigated by studying a variety of other models, includingmodels allowing a large number of life stages, different kinds ofinter-stage competition scenarios, different types of nonlinearities, andcommunities of more than two competing species. The importance of the investigation is to study the underlyingprinciple in theoretical ecology that states coexistence among biologicalspecies requires some sort of niche separation that decreasesinter-specific competition. This project contributes to the understandingof ecological niche and competitive coexistence. Overall, it can lead tothe ability to understand and develop mechanisms to handle problems such asnatural resource management, introduction or re-introduction of speciesinto ecosystems, sustainable yield in the harvesting of ecosystems, andbiocontrol in pest management.
库欣竞争是生物物种之间发生的最基本的相互作用之一。 研究人员仔细研究了衍生的模型,以了解促进在强烈的种间竞争下发生的阶段结构介导的共存现象的数学和生物学机制。 允许降维的特殊情况在研究中特别重要,因为这些情况可以使用稳定性理论和分岔方法进行严格的数学分析。 通过研究各种其他模型来研究竞争共存现象的鲁棒性,包括允许大量生命阶段的模型、不同类型的阶段间竞争场景、不同类型的非线性以及两个以上竞争物种的群落。 这项调查的重要性在于研究理论生态学的基本原理,即生物物种之间的共存需要某种减少物种间竞争的生态位分离。 该项目有助于理解生态位和竞争共存。 总体而言,它可以提高理解和开发机制来处理诸如自然资源管理、将物种引入或重新引入生态系统、生态系统收获中的可持续产量以及害虫管理中的生物防治等问题的能力。
