摘要

在本手稿中,我们试图理解一个具有通性捕食者施加的恐惧的生态系统的延迟诱导(酝酿和结转效应延迟)动力学及其与竞争干扰的结转效应。所设计的模型表现出有限时间炸毁,这取决于大量的初始数据。通过霍普夫分岔分析,对延迟和非延迟系统的稳定性进行了分析。研究发现,在非延迟系统的稳定性控制中,结转效应和恐惧效应的作用是相反的。这两种延迟(滞后效应和酝酿延迟)对动力学有重大影响。前者表现出稳定和失稳两种作用,而后者对系统动力学具有失稳倾向。通过验证分析条件,捕食者物种的炸毁现象得到了数值证明。我们的研究采用了多种图表来说明和支持我们的发现。通过对非线性模型的探索,我们的研究揭示了一些耐人寻味的特征。这些见解对于生物学家寻求更详细、更实用地了解捕食者-猎物系统是非常有价值的。我们研究中提供的可视化表述有助于进行全面分析,提高了研究结果对该领域研究人员和从业人员的可及性和适用性。

Deciphering two delay dynamics of ecological system with generalist predator incorporating competitive interference

In this manuscript, an attempt has been made to understand the delay induced (gestation and carry-over effect delay) dynamics of an ecological system with generalist predator exerted fear and its carry-over effect with competitive interference. The designed model exhibits finite time blow up depending on large initial data. The stability of both the delayed and non-delayed systems have been analyzed along with Hopf-bifurcation analysis. It has been observed that carry-over and fear effects act in opposite way in context of stability control for non-delayed system. The two delay (carry-over effect and gestation delay) have significant impact on the dynamics. The former exhibits both stabilizing and destabilizing role while the latter has a destabilizing tendency on the system dynamics. The blow up phenomena for predator species have been shown numerically by verifying the analytical conditions. Our study incorporates a diverse array of figures and diagrams to illustrate and support our findings. Through the exploration of non-linear models, our research unveils several intriguing characteristics. These insights can prove invaluable for biologists seeking a more detailed and pragmatic understanding of generalist predator–prey systems. The visual representations provided in our study contribute to a comprehensive analysis, enhancing the accessibility and applicability of the findings for researchers and practitioners in the field.
