There is increasing evidence that the wellbeing of marine and terrestrial animalsis affected by the exposure to anthropogenic noise (arising from variousindustrial activities; e.g., the Oil & Gas industry), which interferes with signalprocessing or animal communication, or can directly harm animals [1].A major issue regarding the anthropogenic noise is the difficulty of assessing itsimpact, and estimating behavioural effects on animals.The goal of this research is to use mathematical modelling, combined withanalytical techniques and available experimental data, to propose hypothesesregarding the effect of anthropogenic noise (e.g., generated by the Oil & Gasindustry) on the inter-individual communication between the members of small,medium or large animal aggregations. The project will see the development of2D multiscale mathematical models that describe the spatial interactionsbetween animals via sound signals (the models will be generalizations of modelsin [2,3]). To investigate the models developed in this project, various analyticaland numerical techniques will be used. For biological realism, the models will beparametrised with available data regarding animal movement (e.g., speed,turning behaviours) and animal communication (e.g., communication soundlevels, frequency). Finally, the models will be used to test the effect ofanthropogenic noise on disrupting group-level communication, and the potentialconsequences regarding the survival of individuals.This project will not only lead to the development of new computational andanalytical techniques to investigate these mathematical models, but will alsoincrease our understanding of the role of man-made noise on the biologicalmechanisms that disrupt animal movements and behaviour, and eventually leadto better mitigation methods to increase population survival.[1] A.A.

越来越多的证据表明，海洋和陆地动物的福祉受到人为噪声（由各种工业活动产生，例如石油和天然气工业）的影响，这些噪声会干扰信号处理或动物交流，或者可能直接伤害动物[1]。人为噪声的一个主要问题是难以评估其影响，并估计对动物的行为影响。这项研究的目标是使用数学方法 建模，结合分析技术和现有实验数据，提出关于人为噪声（例如石油和天然气工业产生的噪声）对小型、中型或大型动物聚集体成员之间个体间交流的影响的假设。该项目将看到二维多尺度数学模型的发展，这些模型通过声音信号描述动物之间的空间相互作用（这些模型将是[2,3]中模型的概括）。为了研究该项目中开发的模型，将使用各种分析和数值技术。对于生物现实主义，模型将使用有关动物运动（例如速度、转向行为）和动物交流（例如交流声级、频率）的可用数据进行参数化。最后，这些模型将用于测试人为噪声对破坏群体层面的沟通的影响，以及对个体生存的潜在后果。该项目不仅将导致新的计算和分析技术的发展来研究这些数学模型，而且还将加深我们对人为噪声对扰乱动物运动和行为的生物机制的作用的理解，并最终导致更好的缓解方法来增加种群 生存。[1]互诫协会Yim-Hol Chan, D.T.
