摘要：海洋碳酸盐泵对应于通过钙化浮游生物产生和下沉颗粒无机碳（PIC）。在这项研究中，对全球 PIC 存量、海洋颜色产生的产量以及钙化类群的贡献的估计与过去几十年覆盖全球海洋的短期沉积物捕集器的 PIC 通量观测相结合。颗石藻是真光带中主要的钙化浮游生物群，表现出显着的季节性开花模式和明显的依赖于纬度的季节性响应。本研究强调，富光带的 PIC 产量和中上层 PIC 通量因海洋区域、深度和季节而异。 基于沉积物捕集器的 PIC 通量与遥感气候观测之间的地理匹配，揭示了富光带颗粒有机碳 (POC) 的净初级生产 (NPP) 与 PIC 通量之间的相关性。然而，富光带的 PIC 产量与全球范围内的 PIC 通量无关，而仅与特定海洋盆地相关，例如北大西洋和南大洋。尽管优光带的 PIC 产量和 PIC/POC 比率较低，但与赤道和亚热带地区相比，温带和次极地地区在出口 PIC 方面效率更高，而赤道和亚热带地区的 PIC 产量和 PIC/POC 比率在优光带较高。浮游生物物候似乎是 PIC 输出效率 (PIC Eeff) 和 PIC 转移效率 (PIC Teff) 的重要驱动因素。 这项研究表明，“包装因素”，包括生物碳泵的载体（例如海洋雪聚集体、粪便颗粒）和浮游生物网络（例如浮游动物群落、微生物循环），在很大程度上决定了PIC的输出和转移效率。
Abstract: The oceanic carbonate pump corresponds to the production and sinking of particulate inorganic carbon (PIC) by calcifying planktonic organisms. In this study, global estimates of PIC standing stock, production derived from ocean colour, and the contribution of calcifying taxa were combined with PIC flux observations from short-term sediment traps deployed over the past decades, covering the global ocean. Coccolithophores are the main calcifying plankton group in the euphotic zone, exhibiting a significant seasonal blooming pattern and a pronounced latitude-dependent seasonal response. The present study highlights that PIC production in the euphotic zone, and the pelagic PIC flux vary among oceanic regions, depths, and seasons. Based on a geographic matchup between PIC flux from sediment traps and remote sensing climatological observations, a correlation between net primary production (NPP) of particulate organic carbon (POC) in the euphotic zone and PIC flux is revealed. However, PIC production in the euphotic zone is not correlated with PIC flux at a global scale, but only in specific ocean basins, such as the North Atlantic and the Southern Ocean. Despite lower PIC production and PIC / POC ratios in the euphotic zone, temperate and subpolar areas are more efficient at exporting PIC compared to equatorial and subtropical regions, which have higher PIC production and PIC / POC ratios in the euphotic zone. Plankton phenology appears to be an important driver of PIC export efficiency (PIC Eeff) and PIC transfer efficiency (PIC Teff). This study suggests that the “packaging factor”, which includes the vehicles of the biological carbon pump (e.g., marine snow aggregates, fecal pellets) and the plankton network (e.g., zooplankton communities, microbial loop), largely determines PIC export and transfer efficiencies.

摘要：Aurelia coerulea 和 Rhizostoma pulmo 是两种开花形成的 scyphomedusae，具有复杂的生命周期，以底栖 scyphistoma 和远洋水母阶段为特征。了解环境变异如何调节水生动物的发育转变和无性繁殖途径是进化发育生物学的核心，特别是在持续的气候变化下。地中海是气候变化的热点地区，那里不断上升的气温和日益频繁的海洋热浪为研究季节性和极端热条件如何影响生命周期调节提供了自然背景。在这里，我们进行了一项为期九个月的实验，在受控条件下饲养这两种水螅体，再现了 Bages-Sigean 泻湖每周的原位温度变化，并结合两次实验施加的热浪（12 月 6 天 +5°C 和 12 月 +3°C）。 4 月份 5 °C，持续 5 天）。蓝花珊瑚虫表现出很强的发育可塑性，在低温下通过出芽进行增殖，并快速定殖于基质（0. 12 cm² 天 -1 ），然后当温度持续超过 15 °C 时，无性繁殖显着下降。相比之下，R. pulmo 息肉遵循高度保守的发育途径，在整个实验过程中几乎只产生足囊，底物定植最少（每 100 cm² 200 个碟状体），而 R. pulmo 则从 1 月到 7 月表现出较长的颤动期，在 3 月下旬达到顶峰（每 100 cm² > 30 个碟状体）。温度显着调节这两个物种的芽、足囊和球果的产生，但具有相反的最适温度：寒冷条件有利于蓝花球菌的球球化，而变暖则增强了蓝球菌的球球球化。 热浪暴露进一步改变了这些反应，表明对极端事件的环境依赖性发育敏感性。总之，这些结果表明，密切共存的水母动物可以在相同的热状态下表达根本不同的生命周期调节策略，强调发育途径如何调节物种对气候变暖的特异性反应并塑造未来水母繁殖动态。
Abstract: Aurelia coerulea and Rhizostoma pulmo are two bloom-forming scyphomedusae with a complex life cycle characterized by benthic scyphistoma and pelagic medusa stages. Understanding how environmental variability regulates developmental transitions and asexual reproductive pathways in medusozoans is central to evolutionary developmental biology, particularly under ongoing climate change. The Mediterranean Sea is a climate-change hotspot, where rising temperatures and increasingly frequent marine heatwaves provide a natural context to examine how seasonal and extreme thermal conditions shape life-cycle regulation. Here, we conducted a nine-months experiment rearing polyps of both species under controlled conditions that reproduced weekly in situ temperature variations from the Bages-Sigean lagoon, combined with two experimentally imposed heatwaves (+5 °C for 6 days in December and +3.5 °C for 5 days in April). A. coerulea polyps exhibited strong developmental plasticity, proliferating through budding at low temperatures and rapidly colonizing the substrate (0.12 cm² day -1 ), before a marked decline in asexual propagation when temperatures persistently exceeded 15 °C. In contrast, R. pulmo polyps followed a highly conservative developmental pathway, almost exclusively producing podocysts throughout the experiment, with minimal substrate colonization ( 200 ephyrae per 100 cm²), whereas R. pulmo showed an extended strobilation period from January to July, peaking in late March (>30 ephyrae per 100 cm²). Temperature significantly regulated the production of buds, podocysts, and strobilae in both species, but with contrasting thermal optima: cold conditions favored A. coerulea strobilation, whereas warming enhanced R. pulmo strobilation. Heatwave exposure further modified these responses, indicating context-dependent developmental sensitivity to extreme events. Together, these results demonstrate that closely co-occurring medusozoans can express fundamentally different life-cycle regulation strategies under identical thermal regimes, highlighting how developmental pathways may mediate species-specific responses to climate warming and shape future jellyfish bloom dynamics.

Abstract: Laser Raman spectroscopy is a versatile and well-known technique to probe molecular vibrations. The aim of the study is to design and construct a compact, easy-to-use Raman spectrometer and verify its operation. A laser Raman spectrometer was constructed using a blue diode laser module operating at 402 nm, a novel and efficient combination of backscattering and sidescattering collection geometries, and a spectrometer employing an uncooled CCD (charge-coupled device). The choice of the excitation laser wavelength at 402 nm significantly improves the Raman generation efficiency compared to that for excitation lasers operating at longer wavelengths. Off-the-shelf optical components were used throughout the system. The Raman spectrometer is relatively compact and easy to operate. The operation of the Raman spectrometer was verified with well-known molecules. Raman spectra of several sample materials (both liquids and solids) were acquired and presented.
