海洋环带的地形稳定性研究 Topographic Stabilization of Ocean Rings 作者：L. T. Gulliver and T. Radko 期刊：Geophysical Research Letters 开阔海域中的大尺度相干涡旋可以保持其结构和特性长达数年之久。然而，这些涡旋的位涡模式表明，它们是气压不稳定的，因此理应迅速瓦解。这项研究基于海底粗糙度对大尺度海洋环带寿命提出了一个合理解释，粗糙的海底限制了涡旋下层的流动，从而稳定了涡流。我们进行了一系列模拟，其中海底地形由观测推导的Goff-Jordan能谱函数表示。我们证明，粗糙海底稳定了相干涡旋，并显著延长了它们的寿命。相比之下，平滑海底模式中的相同涡旋在几周就表现出强烈的不稳定性和破碎。这说明存在一个临界深度变量，使涡旋无限期地保持稳定和圆对称。我们的研究强调了海底地形在大、中尺度流体动力学中发挥的重要作用。 点击阅览文章全文 （实习生朱珺月编译） Figure 1: The model configuration. The upper plane shows the pattern of the sub-surface potential vorticity in the cyclonic vortex. The vortex is located above the irregular seafloor (brown surface) with the depth variance of Hrms = 305 m. Only a fraction (400 × 400 km in x and y) of the computational domain is shown. Coherent large-scale vortices in the open ocean can retain their structure and properties for periods as long as several years. However, the patterns of potential vorticity in such vortices suggest that they are baroclinically unstable and therefore should rapidly disintegrate. This study proposes a plausible explanation of the longevity of large-scale ocean rings based on bottom roughness, which restricts flow in the lower layer and thereby stabilizes the eddy. We perform a series of simulations in which topography is represented by the observationally derived Goff-Jordan spectrum. We demonstrate that topography stabilizes coherent vortices and dramatically prolongs their lifespan. In contrast, the same vortices in the flat-bottom model exhibit strong instability and fragmentation on the timescale of weeks. A critical depth variance exists that allows vortices to remain stable and circularly symmetric indefinitely. Our investigation underscores the essential role played by topography in the dynamics of large- and meso-scale flows.

Luecke, S. J. Constantinou, J. R. Gallant, J. K. Eberhart, and H. H. Zakon 期刊：Science Advances 南美洲弱电鱼和非洲弱电鱼各自独立地从肌肉中进化出电器官。在这两种鱼中，电压门控钠通道基因都独立地从肌肉中失去表达，而在电器官中获得表达，使该通道成为产生电信号的专用通道。目前尚不清楚这种电压门控钠通道基因如何靶向调控任一脊椎动物的肌肉。我们描述了一种增强子，选择性地靶向肌肉中钠通道的表达。接下来，我们展示了这种增强子（而非反式激活因子）的缺失是如何导致南美电鱼肌肉中钠通道基因表达缺失的。虽然这种增强子在非洲电鱼中也发生了改变，但关键的转录因子结合位点和增强子活性仍被保留，这表明在这两种电鱼谱系中，肌肉中钠通道表达的趋同缺失是通过不同路径发生的。 点击阅览文章全文 （实习生周敏编译）

Figure 2: Gymnotiform electric fish and their EOs. Some lineages generate sinusoidal EODs (wave EOD); others generate brief pulsatile EODs (pulse EOD). The structure of the electrocytes, the single cells that comprise the EO, is schematically represented to the right. Wave fish have simple, cylindrical electrocytes that resemble elongated muscle fibers, whereas the pulse fish have more complex, derived electrocytes with box-like shapes [the most extreme variant is observed in the electric eel (E. electricus), in which the electrocytes are thin, pancake-like cells]. The gymnotiform species used in this study are identified in their relative phylogenetic position according to (14).

South American and African weakly electric fish independently evolved electric organs from muscle. In both groups, a voltage-gated sodium channel gene independently lost expression from muscle and gained it in the electric organ, allowing the channel to become specialized for generating electric signals. It is unknown how this voltage-gated sodium channel gene is targeted to muscle in any vertebrate. We describe an enhancer that selectively targets sodium channel expression to muscle. Next, we demonstrate how the loss of this enhancer, but not trans-activating factors, drove the loss of sodium channel gene expression from muscle in South American electric fish. While this enhancer is also altered in African electric fish, key transcription factor binding sites and enhancer activity are retained, suggesting that the convergent loss of sodium channel expression from muscle in these two electric fish lineages occurred via different processes.

大量的多倍体克隆是海草扩张到新的水下环境的成功策略 Extensive Polyploid Clonality Was a Successful Strategy for Seagrass to Expand into a Newly Submerged Environment

作者：J. M. Edgeloe, A. A. Severn-Ellis, P. E. Bayer, S. Mehravi, M. F. Breed, S. L. Krauss, J. Batley, G. A. Kendrick, and E. A. Sinclair 期刊：Proceedings of the Royal Society B 多倍体生物有可能在竞争中超越其二倍体祖先，并占领新的环境。西澳大利亚的鲨鱼湾是世界遗产保护区，以温带海草草甸为主，包括波希多尼亚带状杂草——澳大利亚海神草（Posidonia australis）。这种海草位于其自然地理范围的北部，经历着极端的温度和盐度。我们对10处受到地理限制的草甸进行了基因组和细胞遗传学评估，仅在一处发现二倍体克隆（2n=20），而其他所有位置则是单一植株的、广泛分布的、高杂合度的多倍体克隆（2n = 40）。该多倍体克隆至少绵延180公里，是地球上已知最大的克隆体。通过多倍体的全基因组复制，结合克隆性，可能提供了一种机制，使澳大利亚海神草扩展到新的栖息地，并适应了对其二倍体祖先来说变得压力渐增的新环境。这种新的多倍体无性系可能是8500年前鲨鱼湾被淹没后在浅水区形成的，随后通过营养生长扩展到新的水下栖息地。 点击阅览文章全文 （实习生周敏编译）

Broken line indicates the 2.8% cut-off for SNP calling error, as defined by technical replicates. Karyotypes are indicated along the branches, Guischenault Point clade (light blue closed circle) 2n = 20, all other sites are 2n = 40; clade 1 (southwest) Nanga Bay (black closed circle), White Island (brown closed circle); clade 2 (northern) Dirk Hartog Island (black closed circle), Herald Bight (purple closed circle); clade 3 (widespread) Middle Bluff (yellow closed circle), Fowlers Camp (green closed circle), Nanga Bay (black closed circle), Herald Bight (purple closed circle), Monkey Mia (grey closed circle), Dubaut Point (brown closed circle) and Faure sill (blue closed circle); clade 4 low-frequency genotype at Fowlers Camp (green closed circle). (b) Admixture results for optimal K ancestral populations, where K = 2. Each bar corresponds to an individual, with shared colour indicating genetic homogeneity. See table 1 for abbreviations.

Polyploidy has the potential to allow organisms to outcompete their diploid progenitor(s) and occupy new environments. Shark Bay, Western Australia, is a World Heritage Area dominated by temperate seagrass meadows including Poseidon's ribbon weed, Posidonia australis. This seagrass is at the northern extent of its natural geographic range and experiences extremes in temperature and salinity. Our genomic and cytogenetic assessments of 10 meadows identified geographically restricted, diploid clones (2n = 20) in a single location, and a single widespread, high-heterozygosity, polyploid clone (2n = 40) in all other locations. The polyploid clone spanned at least 180 km, making it the largest known example of a clone in any environment on earth. Whole-genome duplication through polyploidy, combined with clonality, may have provided the mechanism for P. australis to expand into new habitats and adapt to new environments that became increasingly stressful for its diploid progenitor(s). The new polyploid clone probably formed in shallow waters after the inundation of Shark Bay less than 8500 years ago and subsequently expanded via vegetative growth into newly submerged habitats.

捕食者对性信号的利用：一项元分析 The Exploitation of Sexual Signals by Predators: a Meta-analysis

作者：T. E. White, T. Latty, and K. D. L. Umbers 期刊：Proceedings of the Royal Society B 性信号通常是繁殖的核心。表达性信号被认为是需要平衡求偶的需求和由于捕食者“窃听”而被发现的风险。然而，对预测捕食成本的测试产生了复杂的结果。在此，我们从78项实验研究中综合归纳出187种效应，试图通过这种元分析测试回答两个问题：即捕食者、寄生生物和拟寄生生物是否对猎物的性信号表现出偏好，以及性信号是否会增加在野外被捕食的风险。我们发现，在迫选范式的实验情景下，捕食者和拟寄生生物对信号表现出强烈且一致的偏好。在野外环境中，对性信号者的捕食总体上也有类似的显著增加，尽管信号的属性存在特异性。相对于视觉信号，嗅觉和听觉信号增加了窃听的发生率，而通常视觉信号的风险不比对照组大。对结果测量的差异普遍很高，这表明性信号可能不会“产生成本”（引来危险），甚至会减少捕食的发生率，这种情况很常见。研究结果揭示了性信号所产生的核心生存能力成本中意想不到的复杂性；同时也谈到了入侵生物学和害虫管理的应用问题，在这些领域，信号的开发为仿生解决方案提供了希望。 点击阅览文章全文 （实习生周敏编译）

Figure 4: Forest plots depicting the meta-analytic mean effect of sexual signalling on the preference of predators eavesdroppers (a) and the risk of predation eavesdropping (b), as well as the mean effects within each signalling modality as estimated via moderator analyses. For preference assays the displayed effects are proportions back-transformed from logits, while Hedges’s g was used to summarize the results of predation risk assays. Points are scaled by the precision of each estimate, and solid lines denote 95% confidence intervals while broken lines indicate 95% prediction intervals.

Sexual signals are often central to reproduction, and their expression is thought to strike a balance between advertising to mates and avoiding detection by predatory eavesdroppers. Tests of the predicted predation costs have produced mixed results, however. Here we synthesized 187 effects from 78 experimental studies in a meta-analytic test of two questions; namely, whether predators, parasites and parasitoids express preferences for the sexual signals of prey, and whether sexual signals increase realized predation risk in the wild. We found that predators and parasitoids express strong and consistent preferences for signals in forced-choice contexts. We found a similarly strong overall increase in predation on sexual signallers in the wild, though here it was modality specific. Olfactory and acoustic signals increased the incidence of eavesdropping relative to visual signals, which experienced no greater risk than controls on average. Variation in outcome measures was universally high, suggesting that contexts in which sexual signalling may incur no cost, or even reduce the incidence of predation, are common. Our results reveal unexpected complexity in a central viability cost to sexual signalling, while also speaking to applied problems in invasion biology and pest management where signal exploitation holds promise for bio-inspired solutions.

光养性海绵动物的生产力在全球高二氧化碳浓度的环境中可能无法提高 Phototrophic Sponge Productivity May Not Be Enhanced in A High CO2 World

作者：J. J. Bell, M. Shaffer, H. M. Luter, R. Mana, and R. Rodolfo-Metalpa 期刊：Global Change Biology 海绵动物是全球底栖生物群落的主要组成部分，由于其对海洋变暖和酸化（OA）的耐受性，被视为全球气候变化下珊瑚礁的潜在“赢家”。先前的研究也假设，含有光合共生体的海绵动物在未来的OA条件下可能具有更高的生产力，因为光合共生体吸收更多二氧化碳，进而增加固碳量。我们在巴布亚新几内亚一处有CO2泄漏的地方模拟OA环境，对一种分布广泛且富含光合共生体的海绵物种——Lamellodyside herbacea进行了假设的验证。我们发现CO2泄漏处海绵的蓝藻丰度、叶绿素浓度和共生体光合效率相比非泄漏处海绵更高，泄漏处海绵的丰度是非泄漏处海绵的三倍。然而，虽然两处海绵的总产氧量相同，但泄漏处海绵的暗呼吸速率较高，光合/呼吸比（P:R）较低。研究表明，虽然含有光合共生物的海绵在OA环境下可能不会提高生产力，但它们能够在与微生物的结合中更为灵活，并抵消与气候变化相关的胁迫造成的代谢成本增加。 点击阅览文章全文 （实习生朱珺月编译）

Figure 5: The abundance (± SE) of different benthic community groups at seep and control reefs in Ambitle. CCA, crustose coralline algae; M/T, macroalgae and turf; OI, other benthic invertebrates; BS, bare space suitable for colonization; US, abiotic substrate not suitable for growth (sand and silt); UN, ‘undetermined’.

Sponges are major components of benthic communities across the world and have been identified as potential “winners” on coral reefs in the face of global climate change as result of their tolerance to ocean warming and acidification (OA). Previous studies have also hypothesised that photosymbiont-containing sponges might have higher productivity under future OA conditions as a result of photosymbionts having increased access to CO2 and subsequently greater carbon production. Here we test this hypothesis for a widespread and abundant photosymbiont-containing sponge species Lamellodysidea herbacea at a CO2 seep in Papua New Guinea simulating OA conditions. We found seep sponges had relatively higher cyanobacterial abundance, chlorophyll concentrations and symbiont photosynthetic efficiency than non-seep sponges, and a three-fold higher sponge abundance at the seep site. However, while gross oxygen production was the same for seep and non-seep sponges, seep sponge dark respiration rates were higher and instantaneous photosynthesis: respiration (P:R) ratios were lower. We show that while photosymbiont containing sponges may not have increased productivity under OA, they are able to show flexibility in their relationships with microbes and offset increased metabolic costs associated with climate change associated stress.

单传感器控制海洋蓝细菌中锌配额的巨大变化 A Single Sensor Controls Large Variations in Zinc Quotas in a Marine Cyanobacterium

作者：A. Mikhaylina, A. Z. Ksibe, R. C. Wilkinson, D. Smith, E. Marks, J. P. C. Coverdale, V. Fülöp, D. J. Scanlan, and C. A. Blindauer  期刊： Nature Chemical Biology  海洋蓝细菌是全球营养物质循环中的重要参与者，该循环主要依赖于金属酶中的痕量金属，包括用于固定二氧化碳和获取磷的锌。目前尚不清楚在超低锌浓度下，菌株是如何在巨大的寡营养海洋环流中增殖并茁壮成长的。以聚球菌WH8102为模型，我们发现其锌传感器蛋白Zur与所有其他已知细菌Zur蛋白在整体结构和锌传感位点的位置上都有所不同。独特的是，聚球菌Zur可以激活金属硫蛋白基因表达，从而支持细胞锌配额跨越两个数量级。因此，单个锌传感器能促进锌浓度从皮摩尔跨越到微摩尔的增长，并附带将锌这一宝贵资源储存起来。这种在超低锌和过量锌条件下均能生长良好的能力，以及总体较低的锌需求量，有助于聚球菌在全球海洋的广泛生态分布。 点击阅览文章全文 （实习生周敏编译）

Marine cyanobacteria are critical players in global nutrient cycles that crucially depend on trace metals in metalloenzymes, including zinc for CO2 fixation and phosphorus acquisition. How strains proliferating in the vast oligotrophic ocean gyres thrive at ultra-low zinc concentrations is currently unknown. Using Synechococcus sp. WH8102 as a model we show that its zinc-sensor protein Zur differs from all other known bacterial Zur proteins in overall structure and the location of its sensory zinc site. Uniquely, Synechococcus Zur activates metallothionein gene expression, which supports cellular zinc quotas spanning two orders of magnitude. Thus, a single zinc sensor facilitates growth across pico- to micromolar zinc concentrations with the bonus of banking this precious resource. The resultant ability to grow well at both ultra-low and excess zinc, together with overall lower zinc requirements, likely contribute to the broad ecological distribution of Synechococcus across the global oceans.

在115度纬度跨度范围内，捕食者对海洋群落的控制随温度的升高而增强 Predator Control of Marine Communities Increases with Temperature Across 115 Degrees of Latitude

Ruiz 期刊：Science 早期的博物学家认为，捕食强度从两极向热带地区逐渐增加，从而通过纬度梯度影响基本的生态和进化过程，但这种经验支持还很有限。几项研究在大尺度上测量了整个纬度梯度的捕食强度，结果各不相同。此外，在这样的地理尺度上，捕食如何影响猎物群落组成仍然是未知的。通过在纬度跨度达115°的美洲两岸36个近岸地点的标准化实验，研究发现，在较温暖的热带水域中，海洋捕食者对海洋无脊椎动物群落的生物量和物种组成有更高的捕食强度和持续更强的影响，这可能是鱼类捕食者造成的。我们的研究结果为这种随温度梯度变化的相互作用强度提供了有力的支持，并对海洋生态系统如何应对海洋变暖提供了潜在的见解。 点击阅览文章全文 （实习生朱珺月编译）

Figure 7: Effects of predator treatments on community composition at a tropical Atlantic site and response of key functional groups from models based on all sites. (A to C) Photographs illustrate differences among experimental treatments at Bocas del Toro, Panama. At this and other warm water sites, encrusting bryozoans predominated in (A) control panels (exposed to predators), (B) solitary tunicates in caged panels (predators excluded), and (C) bare space in exposed cage panels [as in (B) but exposed to predators for the last 2 weeks through cage removal]. (D to F): Modeled percent cover across all sites of (D) encrusting bryozoans, (E) solitary tunicates, and (F) bare space, which together explained most of the variation in community composition among treatments (yellow, controls; dark blue, caged; green, exposed cage) in warm water sites. Shaded areas show 95% CIs (24).

Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how predation affects prey community composition at such geographic scales remains unknown. Using standardized experiments that spanned 115° of latitude, at 36 nearshore sites along both coasts of the Americas, we found that marine predators have both higher consumption rates and consistently stronger impacts on biomass and species composition of marine invertebrate communities in warmer tropical waters, likely owing to fish predators. Our results provide robust support for a temperature-dependent gradient in interaction strength and have potential implications for how marine ecosystems will respond to ocean warming.

美国俄勒冈州蓝藻水华产生柱孢藻毒素结构变体 和微囊藻毒素的蓝藻种类来自不同属——鱼腥藻属/长孢藻属/水华束丝藻属 7-Epi-Cylindrospermopsin and Microcystin Producers Among Diverse  Anabaena/Dolichospermum/Aphanizomenon Cyanohabs in Oregon, USA

作者：T. W.Drehera, A. J.Fossb, E. W.DavisIIc, and R. S.Muellera 期刊：Harmful Algae 最近我们对美国西北太平洋地区的念珠藻目下三个属，鱼腥藻属/长孢藻/水华束丝藻属（Anabaena/Dolichospermum/Aphanizomenon, ADA）的几个基因组进行了测序。15株长孢藻/鱼腥藻菌株中有7株存在微囊藻毒素（MC）、柱孢藻毒素（CYN）或鱼腥藻毒素-a的生物合成基因，5株水华束丝藻（AFA）菌株中均不存在以上三种的生物合成基因。毒素分析（酶联免疫吸附测定和液相二级质谱检测）用于定量和鉴定已知基因组序列以长孢菌属为主的样品中的MC和CYN同源物/类似物。MC-LR是Junipers水库、比利奇努克湖和奥德尔湖中长孢菌属产生的主要同系物，而底特律水库的长孢菌属生产的是一种暂时确定为 [Dha7] MC-HtyR 的同系物。底特律水库的第二种长孢藻属产生两种CYN的结构变体 7-epi-CYN 和 7-deoxy-CYN，但没有CYN。这些湖泊的监测历史表明，当蓝藻中长孢藻属占主导时，蓝藻毒素浓度水平高。在美国太平洋西北部发现的ADA菌株的多样性强调了这些蓝藻在这个温带气候地区作为潜在有毒藻华（HAB）形成菌的重要性。我们的结果将同源物和遗传特性联系起来，增加了数据点，这将有助于指导开发从蓝藻毒素基因序列预测同源物特异性的改进工具。 点击阅览文章全文 （实习生朱珺月编译）

Figure 8: MC congeners detected during targeted LC-MS/MS analysis in Dolichospermum-dominated samples collected from three Oregon lakes. MC-LR was the dominant congener detected, followed by the desmethyl derivative [D-Asp3]MC-LR. Minor contributions (< 1% each) of other congeners — desmethylated congeners (dmMC-LR, [Dha7]MC-LR, [DMAdda5]MC-LR, and [D-Asp3]MC-RR), MC-YR, MC-HtyR, MC-HilR, and an unknown MC (m/z 1009.5) — were observed. Dolichospermum sp. OL01 present in samples OL01 and OL02 and Dolichospermum sp. LBC05a present in samples LBC01 and LBC05 have near-identical genomes, including mcy genes, while Dolichospermum sp. JUN01 present in sample JUN03 has closely related mcy genes.

Several genomes of Nostocales ADA clade members from the US Pacific Northwest were recently sequenced. Biosynthetic genes for microcystin, cylindrospermopsin or anatoxin-a were present in 7 of the 15 Dolichospermum/Anabaena strains and none of the 5 Aphanizomenon flos-aquae (AFA) strains. Toxin analyses (ELISA and LC-MS/MS) were conducted to quantitate and identify microcystin (MC) and cylindrospermopsin (CYN) congeners/analogs in samples dominated by Dolichospermum spp. of known genome sequence. MC-LR was the main congener produced by Dolichospermum spp. from Junipers Reservoir, Lake Billy Chinook and Odell Lake, while a congener provisionally identified as [Dha7]MC-HtyR was produced by a Dolichospermum sp. in Detroit Reservoir. A second Dolichospermum sp. from Detroit Reservoir was found to produce 7-epi-CYN, with 7-deoxy-CYN also present, but no CYN. The monitoring history of each of these lakes indicates the capacity for high levels of cyanotoxins during periods when Dolichospermum spp. are the dominant cyanobacteria. The diversity of ADA strains found in the US Pacific NW emphasizes the importance of these cyanobacteria as potentially toxic HAB formers in this temperate climatic region. Our results linking congener and genetic identity add data points that will help guide development of improved tools for predicting congener specificity from cyanotoxin gene sequences.
