Abstract Jellyfish behavior and physiology significantly influence spatial distribution and aggregations in the marine environment. However, current models used to study these transport patterns have a limited incorporation of these physiological and behavioral variables. In this paper, the life cycle and movement of the mauve stinger, Pelagia noctiluca, is simulated from fertilized egg up to the adult stage using an individual-based model (IBM). Our model combines available knowledge on the mauve stinger with inputs of ocean currents and temperature from the CMEMS hydrodynamic model. Horizontal transport is solely governed by ocean currents, but vertical distribution is controlled by diel vertical migration, motility and stage of development. Particle agents are released along the submarine canyons in the Spanish Mediterranean waters during the spring reproduction period, to later disperse and develop through an interplay between physical and biological processes. When compared with a simpler model, that omits behavior and physiology, the biophysical model is able to qualitatively better predict stranding events in the Balearic Sea. Our results expose the potential for operational life stage and distribution modelling of jellyfish.

使用基于个体的模型模拟行为对巴利阿里海中水母紫红色毒刺 (Pelagianoctiluca) 分布的影响

摘要 水母的行为和生理对海洋环境中的空间分布和聚集有显着影响。然而，用于研究这些运输模式的当前模型对这些生理和行为变量的结合有限。在本文中，使用基于个体的模型 (IBM) 模拟了从受精卵到成年阶段的紫红色毒刺 Pelagia noctiluca 的生命周期和运动。我们的模型将有关紫红色毒刺的可用知识与来自 CMEMS 水动力模型的洋流和温度输入相结合。水平运输完全受洋流控制，但垂直分布受日间垂直迁移、运动和发展阶段控制。在春季繁殖期间，粒子剂沿着西班牙地中海水域的海底峡谷释放，随后通过物理和生物过程之间的相互作用分散和发展。与忽略行为和生理的更简单模型相比，生物物理模型能够从质量上更好地预测巴利阿里海的搁浅事件。我们的结果揭示了水母运行生命阶段和分布建模的潜力。
