Abstract

The swarming behavior of certain scyphozoan clades, such as Pelagia noctiluca (Forskål, 1775), highlights an evolutionary advantage. These adaptations promote survival and reproductive success, resulting in mass occurrences. P. noctiluca, notorious for its ecological disruption and harmful stings, swarms in response to nutrient availability. This study is the first to document the co-occurrence of a swarm of P. noctiluca (120–180 ind. m⁻³) and a bloom of Noctiluca scintillans (Macartney) Kofoid & Swezy, 1921 (2.68 x 10³-4.32 × 10³ cells L⁻¹) in the Bay of Bengal, Indian Ocean. The study suggests that N. scintillans grazes on phytoplankton in nutrient-rich waters due to reduced competition from P. noctiluca's opportunistic feeding on zooplankton. This interaction gives N. scintillans a competitive edge, allowing both species to co-exist and significantly impact the marine ecosystem. The proliferation of N. scintillans, supported by favorable conditions, is intertwined with P. noctiluca's feeding dynamics, posing significant ecological and economic challenges. Continuous monitoring is essential to understand the swarming and migration patterns of P. noctiluca in the Indian Ocean, as their outbreaks indicate a broader ecosystem shift influenced by climate change and altered prey availability.

破坏性协同作用：绿鞭毛藻夜光藻（forssk, 1775）与绿鞭毛藻夜光藻（Macartney）共同发生

某些两栖动物分支的群集行为，如夜蛾（Pelagia noctiluca, forsk, 1775），突出了一种进化优势。这些适应促进了生存和繁殖的成功，导致了大规模的发生。夜luca，因其生态破坏和有害的蜇伤而臭名昭著，蜂群是对养分可用性的反应。这项研究首次记录了夜luca （120-180 ind. m - 3）和夜光luca (Macartney) Kofoid开花同时发生的情况。Swezy, 1921 （2.68 × 103-4.32 × 103细胞L−1）在孟加拉湾，印度洋。该研究表明，闪烁螺在营养丰富的水域以浮游植物为食，这是由于夜间螺对浮游动物的机会性取食减少了竞争。这种相互作用使闪烁螺具有竞争优势，使这两个物种能够共存，并对海洋生态系统产生重大影响。夜莺的繁殖在有利条件的支持下，与夜莺的摄食动态交织在一起，构成了重大的生态和经济挑战。持续监测对于了解印度洋夜luca的群体和迁徙模式至关重要，因为它们的爆发表明受气候变化和猎物可得性改变影响的更广泛的生态系统转变。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
