The severity of marine heatwaves (MHWs) that are increasingly impacting ocean ecosystems, including vulnerable coral reefs, has primarily been assessed using remotely sensed sea-surface temperatures (SSTs), without information relevant to heating across ecosystem depths. Here, using a rare combination of SST, high-resolution in-situ temperatures, and sea level anomalies observed over 15 years near Moorea, French Polynesia, we document subsurface MHWs that have been paradoxical in comparison to SST metrics and associated with unexpected coral bleaching across depths. Variations in the depth range and severity of MHWs was driven by mesoscale (10s to 100s of km) eddies that altered sea levels and thermocline depths and decreased (2007, 2017 and 2019) or increased (2012, 2015, 2016) internal-wave cooling. Pronounced eddy-induced reductions in internal waves during early 2019 contributed to a prolonged subsurface MHW and unexpectedly severe coral bleaching, with subsequent mortality offsetting almost a decade of coral recovery. Variability in mesoscale eddy fields, and thus thermocline depths, is expected to increase with climate change, which, along with strengthening and deepening stratification, could increase the occurrence of subsurface MHWs over ecosystems historically insulated from surface ocean heating by the cooling effects of internal waves.

水平基因转移加速了微生物的进化。海洋微型蓝藻Prochlorococcus（原绿球藻）展示了高度的基因组可塑性，而潜在的机制尚不清楚。在此，我们报告了DNA转座子的一个新的家族——“tycheposons”——其中一些是病毒卫星，另一些则携带物质，比如获取营养的基因，这些基因决定了这个全球丰富的属的遗传变异性。Tycheposons 共享独特的与移动生命周期相关的标志基因，包括一个深分支位点特异性的酪氨酸重组酶。它们在tRNA基因上的切除和整合似乎驱动了基因组岛的重塑，这是细菌中灵活基因的关键库。在一个选择实验中，动态获得和丢去携带硝酸盐同化盒的tycheposons，从而促进了染色体的重新排列和宿主的适应。从海水中获得的囊泡和噬菌体颗粒中富含tycheposons，为其在野外的传播提供途径。类似的元件也在与原绿球藻共生的微生物中被发现，这意味着在广阔的寡营养海洋中有一种对于微生物多样化的共同机制。

Fig. 2 Structure and function of tycheposons in Prochlorococcus

(A and B) Examples of two types of tycheposons illustrating their modular structure: (A) cargo-carrying tycheposons selected here because of their clear ecological relevance in ocean ecosystems, and (B) satellite tycheposons, carrying either a terS or MCP viral-packaging gene likely used to hijack phage capsids for dispersal. Cargo modules were annotated with roles in nitrate assimilation,³¹ siderophore transport,¹⁸ phosphate assimilation,³² zinc homeostasis,³³ and phosphite assimilation.³⁴

Gene labels: full-length and partial tRNA genes are labeled with single-letter amino acid code and their anticodon, e.g., Stga, tRNA-serineTGA; YR, tyrosine recombinase; MCP, major capsid protein; terS, terminase small subunit; xis, excisionase; hel, helicase; top, topoisomerase; lig, ligase; reg, transcriptional regulator; pri, primase, primase/polymerase, or primase/helicase; end, endonuclease; SSR, small serine recombinase; unk, conserved unknown. Some annotations are further labeled with more specific subprofiles indicating specific families of helicases, for example (helDnaB or helVirE). 

Horizontal gene transfer accelerates microbial evolution. The marine picocyanobacterium Prochlorococcus exhibits high genomic plasticity, yet the underlying mechanisms are elusive. Here, we report a novel family of DNA transposons—“tycheposons”—some of which are viral satellites while others carry cargo, such as nutrient-acquisition genes, which shape the genetic variability in this globally abundant genus. Tycheposons share distinctive mobile-lifecycle-linked hallmark genes, including a deep-branching site-specific tyrosine recombinase. Their excision and integration at tRNA genes appear to drive the remodeling of genomic islands—key reservoirs for flexible genes in bacteria. In a selection experiment, tycheposons harboring a nitrate assimilation cassette were dynamically gained and lost, thereby promoting chromosomal rearrangements and host adaptation. Vesicles and phage particles harvested from seawater are enriched in tycheposons, providing a means for their dispersal in the wild. Similar elements are found in microbes co-occurring with Prochlorococcus, suggesting a common mechanism for microbial diversification in the vast oligotrophic oceans.

海洋鱼类利用Slc4a11A生电硼酸转运机制，经肾脏排出硼酸

Seawater Fish Use an Electrogenic Boric Acid Transporter, Slc4a11A, for Boric Acid Excretion by the Kidney

作者: Akira Kato, Yuuri Kimura, Yukihiro Kurita, Min-Hwang Chang, Koji Kasai, Toru Fujiwara , Taku Hirata, Hiroyuki Doi, Shigehisa Hirose, and Michael F. Romero

期刊:Journal of Biological Chemistry

硼酸是动物体内重要的微量营养素，但若过量则会产生毒性。然而，人们对动物全身的硼酸内稳态知之甚少。海水（SW）含有0.4 mM的硼酸，且海洋鱼类会吸入海水，因此，本研究将海洋鱼类的泌尿系统作为硼酸排出系统的模型。我们对一种广盐性河鲀（河豚/暗纹东方鲀）进行了研究，发现其适应淡水时膀胱尿液含有0.020mM的硼酸，适应海水时则是19 mM（后者是前者的950倍），这表明存在强大的泌尿排泄系统可排出硼酸。Slc4a11存在于动物体内，是编码植物硼转运蛋白BOR1同源的蛋白质的未表征基因；然而，哺乳动物的Slc4a11虽能调节H⁺ (OH^-)的传导，但无法转运硼酸。将河豚从淡水转移到海水后，我们发现其Slc4a11旁系基因Slc4a11A的肾脏表达明显受到诱导，且Slc4a11A定位于肾小管的顶端膜。当河豚的Slc4a11A基因在非洲爪蟾卵母细胞中表达时，接触含有硼酸的介质和电压钳导致产生全细胞外向电流，pH_i值明显增加，硼含量增加。此外，Slc4a11A的活性与胞外Na⁺无关。以上结果表明河豚Slc4a11A是一种可生电的硼酸转运机制，与B(OH)₄^-单转运蛋白、B(OH)₃-OH^-协同转运蛋白或B(OH)₃/H⁺交换蛋白的功能相同。这些观察表明，Slc4a11A参与了海洋鱼类肾小管的硼酸排出，原因或为负膜电位和低尿液pH值。

Fig. 3 Renal expression of Slc4a11A. A, phylogenetic tree of boric acid transporters in relation to the other human SLC4 family members. The boric acid transport activity of Takifugu Slc4a11A is shown in this study. The scale bar represents 0.1 amino acid substitution per site. B, tissue distribution of Slc4a11A and Slc4a11B. Semiquantitative RT–PCR was performed on various tissues of river pufferfish. Numbers indicate PCR cycles. Results from 27 PCR cycles show tissues with relatively high expression of the indicated genes, and those of 32 cycles show all tissues expressing the indicated genes from low to high levels (111, 162, 65). C, real-time PCR quantification of mRNAs for Slc4a11A and Slc4a11B in the kidneys of river pufferfish acclimated to FW and SW. Values are expressed relative to GAPDH. Dots represent individual data. Bar graphs represent means ± SD, n = 5. ∗p < 0.05. D, in situ hybridization of Slc4a11A and Slc4a11B in the kidney of river pufferfish in SW. Sense probes did not show labeling (data not shown). AE, anion exchanger; c, chicken; F, FW; NBC, Na-HCO⁺₃^– cotransporter; NDCBE, Na-driven Cl^+-/HCO⁺₃^– exchanger; S, SW; SLC4, solute carrier family 4; z, zebrafish.

Boric acid is a vital micronutrient in animals; however, excess amounts are toxic to them. Little is known about whole-body boric acid homeostasis in animals. Seawater (SW) contains 0.4 mM boric acid, and since marine fish drink SW, their urinary system was used here as a model of the boric acid excretion system. We determined that the bladder urine of a euryhaline pufferfish (river pufferfish, Takifugu obscurus) acclimated to fresh water and SW contained 0.020 and 19 mM of boric acid, respectively (a 950-fold difference), indicating the presence of a powerful excretory renal system for boric acid. Slc4a11 is a potential animal homolog of the plant boron transporter BOR1; however, mammalian Slc4a11 mediates H⁺(OH⁻) conductance but does not transport boric acid. We found that renal expression of the pufferfish paralog of Slc4a11, Slc4a11A, was markedly induced after transfer from fresh water to SW, and Slc4a11A was localized to the apical membrane of kidney tubules. When pufferfish Slc4a11A was expressed in Xenopus oocytes, exposure to media containing boric acid and a voltage clamp elicited whole-cell outward currents, a marked increase in pHi, and increased boron content. In addition, the activity of Slc4a11A was independent of extracellular Na. These results indicate that pufferfish Slc4a11A is an electrogenic boric acid transporter that functions as a B(OH)₄⁻ uniporter, B(OH)₃-OH⁻ cotransporter, or B(OH)₃/H⁺ exchanger. These observations suggest that Slc4a11A is involved in the kidney tubular secretion of boric acid in SW fish, probably induced by the negative membrane potential and low pH of urine.

浮游植物营养吸收的可塑性维持了未来海洋的净初级生产力

Nutrient Uptake Plasticity in Phytoplankton

Sustains Future Ocean Net Primary Production

期刊： Science Advances

每年海洋中的浮游植物将大约500亿吨的溶解无机碳转变为颗粒物和溶解有机碳，其中一部分通过生物碳泵输出到海洋深处。尽管浮游植物在通过固碳调节大气二氧化碳和维持海洋生态系统方面发挥重要作用，但利用模型预测的未来海洋净初级生产力的变化具有高度的不确定性，甚至连变化的标志也是如此。本文中我们通过采用一种地球系统模型表明浮游植物在磷酸盐胁迫条件下对磷的节约利用可以过度补偿之前预测的21世纪由于海洋变暖和分层增强现象所带来的下降。本研究模拟结果与夏威夷海洋时间序列（Hawaii Ocean Time-series）项目实地观测结果一致，即在全球变暖情况下，亚热带海洋中浮游植物利用磷的适应性变化对维持浮游植物生产力和碳输出能力具有重要的调节作用。

Fig. 4 Relationships between surface PO₄ and the C:P ratio of suspended and sinking particles.

(A) Time series of monthly mean PO₄ concentrations (blue) and the ratio of PC concentration to PP concentration (red) averaged over depths of 0 to 125 m at Station ALOHA. The C:P ratios before November 2011 (a time of PP measurement method change) are shown as open diamonds, and those since November 2011 are shown as filled diamonds. Shaded red and blue lines are 12-month moving averages of the respective monthly mean data. The PO₄ concentrations lower than a P-stressed threshold of 0.06 μmol kg⁻¹ (26) are shaded in purple. (B) Scatter plot showing the C:P ratios of suspended particles in the y axis and the surface PO₄ concentrations in the x axis. The ALOHA time-series data [presented in (A)] are shown in dark blue dots. The climatological mean spatially distributed data (gray dots) are taken from (32) and (33). The BATS time-series data are taken from (15) and plotted in sky blue dots. The two empirical relationships previously derived on the basis of the spatial data are shown as red [hyperbolic; Galbraith and Martiny (9)] and purple [power law; Tanioka and Matsumoto (18)] lines. The best fit to the ALOHA time-series data, P:C = (12.2 ± 7.4)‰ (per mil) × [PO₄] + (5.8 ± 0.5)‰, is shown in yellow solid line with an SE denoted as yellow dashed lines. (C) Oligotrophic portion of (B) is zoomed in. (D) Scatter plot showing the C:P ratios of sinking particles at 150 m in the y axis and the surface PO₄ concentrations in the x axis. The best fit to the ALOHA time-series data is P:C = (17.2 ± 8.3)‰ × [PO₄] + (3.9 ± 0.5)‰.

Annually, marine phytoplankton convert approximately 50 billion tons of dissolved inorganic carbon to particulate and dissolved organic carbon, a portion of which is exported to depth via the biological carbon pump. Despite its important roles in regulating atmospheric carbon dioxide via carbon sequestration and in sustaining marine ecosystems, model-projected future changes in marine net primary production are highly uncertain even in the sign of the change. Here, using an Earth system model, we show that frugal utilization of phosphorus by phytoplankton under phosphate-stressed conditions can overcompensate the previously projected 21st century declines due to ocean warming and enhanced stratification. Our results, which are supported by observations from the Hawaii Ocean Time-series program, suggest that nutrient uptake plasticity in the subtropical ocean plays a key role in sustaining phytoplankton productivity and carbon export production in a warmer world.

从水源地青藏高原到海洋：与土地利用变化和气候变异相关的长江营养盐状况

From the Water Sources of the Tibetan Plateau

to the Ocean: State of Nutrients in the Changjiang

Linked to Land Use Changes and Climate Variability

作者：Jing Zhang, Guosen Zhang, Yanan Du, Anyu Zhang, Yan Chang, Yingchun Zhou, Zhuoyi Zhu, Ying Wu, Zaifeng Zhang, and Sumei Liu 

期刊：Science China Earth Sciences

人类活动是次大陆尺度（例如100万平方公里）流域中营养盐（N、P和Si）化学组分变化的一个重要驱动因素，并可显著改变其入海通量。本文研究了长江营养盐的现状，数据来自1997至2016年间11次流域考察，涵盖了约4500公里的干流和15至20条主要支流，以及1980年以来在河口的月度观测数据。结合已发表的文献结果，本文综合分析了长江营养盐的变化和现状；为实现对整个流域营养盐的系统性研究，将青藏高原水系源头的研究成果也包括在内。研究表明，流域上游的支流共同决定了长江干流中营养盐的高浓度和比例失衡，并对下游2000-2500公里直至河口产生显著影响。此外，利用2003-2016年三峡水库的数据，评估了三峡大坝对营养盐的截留和/或放大效应。受潮汐影响的河流三角洲为入海通量贡献了20%的溶解无机磷和5-10%的溶解无机氮和溶解硅酸盐，极大地影响了河口营养盐的化学计量。然后，根据汇编的营养盐收支数据，对营养盐盈余进行了估算。流域内氮和磷均处于积累阶段，营养盐盈余量远高于入海通量。最后，研究得出长江水体中来源于人类活动的营养盐入海通量超过了地球上其他十大河流，主要受过去三、四十年土地利用变化的影响。

Fig. 5 (Color online) (1a) Watersheds of the Changjiang (Yangtze River), with important sampling sites and the major tributaries sampled during field expeditions in 1997–2016, and the Nantong and Xuliujing (XLJ) monitoring stations are marked. (1b) Connection of the Qinghai-Tibetan Plateau (Qingzang Gaoyuan) and the watersheds of Changjiang, the figure is modified from the Ministry of Natural Resources (Web-site: http://bzdt.ch.mnr.gov.cn/browse.html? picId=%224o28b0625501ad13015501ad2bfc0065%22), The pink and orange areas represents Qinghai-Tibetan Plateau and the watersheds of Changjiang, respectively. (1c) Changes in riverbed elevation, water discharge, and catchment area along the river course sampled. The geographic separation between the Changjiang and the East China Sea is defined by the line between the tips of Qidong (QD) to the north and Nanhui (NH) to the south at river mouth. Stations and name abbreviations include: SG (Shigu), JH (Jinhe), PZH (Panzhihua), XJB (Xiangjiaba), YB (Yibin), JJ (Jiangjin), CD (Chengdu), CQ (Chongqing), CT (Cuntan), WZ (Wanzhou), YC (Yichang), YY (Yueyang), CS (Changsha), WH (Wuhan), NC (Nanchang), HK (Hukou), AQ (Anqing), HF (Hefei), DT (Datong), NJ (Nanjing), ZJ (Zhenjiang), SZ (Suzhou), XLJ (Xuliujing and Nantong), QD (Qidong), SH (Shanghai), and NH (Nanhui). Black letters show the geographic locations, and blue circles indicate the sampling stations along the river mainstream. The area marked by orange color indicates the water surface area of the Three Gorges Reservoir (TGR) with the dam (i.e., TGD) site that is ca. 30 km upstream the Yichang.

Anthropogenic activity is an important driver of changes in the chemistry of nutrients (N, P, and Si) over watersheds at the sub-continental scale (e.g., 10⁶ km²) and can markedly modify their seaward fluxes to the global ocean. In the present study, we reviewed the current status of nutrient chemistry in Changjiang (Yangtze River) based on data collected through 11 expeditions along a river course spanning 4,500 km and 15–20 major tributaries during 1997–2016 as well as monthly monitoring at the river mouth since 1980. The data were analyzed together with published results in the literature to synthesize the recent developments and current state of nutrients in the Changjiang. Previously published results from the Qinghai-Tibetan Plateau head waters were included to realize the systematics of nutrients for the whole drainage basin. Here, we showed that tributaries of the upper reaches of watersheds collectively determine the regime with high concentration and skewed species ratio of nutrients in the Changjiang mainstream, producing profound effects over a water course of 2,000–2,500 km further downstream and until the river mouth. Moreover, using data across the Three Gorges Reservoir (TGR) during 2003–2016, we evaluated the trapping and/or amplifying effects of the Three Gorges Dam (TGD) on nutrient chemistry. Tide-influenced river delta contributed an additional 20% dissolved inorganic phosphorus and 5–10% dissolved inorganic nitrogen and dissolved silicates to the seaward flux, dramatically affecting the stoichiometry of nutrients at the river mouth. Next, based on compiled data on supply and export, legacy nutrients were evaluated. Both nitrogen and phosphorus are in the accumulation phase over the watersheds, and the legacy nutrient fluxes are much higher than the annual riverine seaward fluxes. Finally, we demonstrated that the seaward fluxes of anthropogenic nutrients from the Changjiang exceed those from other top 10 largest rivers on this planet, which can be attributed to land use changes in the China over the last three to four decades.

由浮游植物生态生理学驱动的海洋有机质化学计量的全球模式

Global Patterns in Marine Organic Matter

Stoichiometry Driven by Phytoplankton Ecophysiology

作者：Keisuke Inomura, Curtis Deutsch, Oliver Jahn, Stephanie Dutkiewicz, and Michael J. Follows

期刊：Nature Geoscience

海洋有机物中主要元素的比例将细胞活动过程与全球营养物、氧气以及碳循环联系起来。在海洋生物群落之间已经观测到有机物C:N:P比值（碳氮磷比值）的差异，但在小规模的生理和生态过程中这些差异模式尚未被量化。本文中我们使用了一种生态模型，这个模型中包含了生态学水平上大小截然不同的浮游生物内部和相互之间的适应性资源分配，以确定影响C:N:P比值中全球模式的因素。我们发现N:C比值（氮碳比值）的变化很大程度上是由所有浮游植物共同的生理调节策略所驱动，而N:P比值（氮磷比值）的模式变化则是由不同储磷能力的分类群生态选择所驱动。尽管N:C比值（氮碳比值）因细胞会对光照和营养物质的调整而变化很大，但因为营养物质和光照供应之间的平衡随深度而变化，其纬度梯度变化不大。N:P比值（氮磷比值）在纬度上的大幅度变化反映了这样一种生态平衡，即亚热带地区偏好具有较低储磷能力的小型浮游生物，而营养丰富的高纬度地区则偏好具有较高细胞储磷能力的较大真核生物。南半球和北半球，大西洋和太平洋之间较小的N:P比值（氮磷比值）差异反映了可用于细胞储存的磷酸盐的差异性。尽管只模拟了两种大小等级的浮游植物，但元素比例的全球差异性与所有观测物种相似，研究表明生长条件的范围与生态选择维持了所观测到的浮游植物间化学计量的多样性。

Fig. 6 a,b, Variations in elemental ratios in ‘small’ (prokaryotic) phytoplankton (a) and ‘large’ (eukaryotic) phytoplankton (b). Colour shading indicates N:P, computed as the ratio of N:C (x axis) and P:C (y axis). Laboratory data for small prokaryotic cells (white points, a) and eukaryotic cells (white points, b) at a variety of growth rates and light intensities (excluding a few outliers) (see Supplementary Data and references there). Arrows indicate the stoichiometric ratios predicted by the allocation model decomposed into structural and storage components based on average nutrient and light conditions from the surface ocean at 50° S, where N and P nutrients are largely replete. Lilac arrows indicate the modelled contribution from acclimation in the absence of P storage. Observed points fall above those lines due to P storage, the sense of which is indicated by the light blue vectors (modelled P storage). Larger, eukaryotic cells in b are associated with higher storage contributions (longer blue vector) than smaller prokaryotic cells in a. c, Differences in P storage between small and large plankton size classes in the model are based on empirical estimates derived from laboratory studies of prokaryotic^20,39 and eukaryotic⁴⁴ phytoplankton (n = 43 and 28 for prokaryotes and eukaryotes, respectively. A few data with excess growth-limiting nutrients at the steady state³⁹ are not included). The box represents median (centre line) and first and third quartiles (box). The whiskers represent the value range without outliers (those outside the box by 1.5 times the interquartile range). The P storage is estimated based on the differences in P:C under N and P limitations for closest growth rates.

The proportion of major elements in marine organic matter links cellular processes to global nutrient, oxygen and carbon cycles. Differences in the C:N:P ratios of organic matter have been observed between ocean biomes, but these patterns have yet to be quantified from the underlying small-scale physiological and ecological processes. Here we use an ecosystem model that includes adaptive resource allocation within and between ecologically distinct plankton size classes to attribute the causes of global patterns in the C:N:P ratios. We find that patterns of N:C variation are largely driven by common physiological adjustment strategies across all phytoplankton, while patterns of N:P are driven by ecological selection for taxonomic groups with different phosphorus storage capacities. Although N:C varies widely due to cellular adjustment to light and nutrients, its latitudinal gradient is modest because of depth-dependent trade-offs between nutrient and light availability. Strong latitudinal variation in N:P reflects an ecological balance favouring small plankton with lower P storage capacity in the subtropics, and larger eukaryotes with a higher cellular P storage capacity in nutrient-rich high latitudes. A weaker N:P difference between southern and northern hemispheres, and between the Atlantic and Pacific oceans, reflects differences in phosphate available for cellular storage. Despite simulating only two phytoplankton size classes, the emergent global variability of elemental ratios resembles that of all measured species, suggesting that the range of growth conditions and ecological selection sustain the observed diversity of stoichiometry among phytoplankton.
