To capture prey more efficiently, cetaceans can display a wide range of foraging tactics to separate individual prey. Barrier feeding tactics are performed to restrict prey movements, using natural and non-natural barriers and some species can even create barriers with their own bodies. Mud ring feeding has been observed in bottlenose dolphins in Florida Bay and in Chetumal-Corozal Bay, where ring-maker dolphins create ring-shaped mud plumes to encircle fish schools. Here, we document for the first time Guiana dolphins performing the mud ring feeding behaviour in the Cananéia estuarine system, in the southern portion of the state of São Paulo, Brazil. A total of 11 dolphins were recorded in four expeditions through aerial footage engaging in the behaviour. These findings expand our knowledge about the behavioural plasticity of the species and builds upon existing records of mud ring feeding behaviour in cetaceans.
为了更有效地捕获猎物,鲸目动物可以采取多种觅食策略来分离猎物个体。障碍捕食战术是利用自然和非自然的障碍物来限制猎物的行动,有些物种甚至可以用自己的身体制造障碍物。在佛罗里达湾和切图马尔-科罗萨尔湾的瓶鼻海豚身上观察到了泥环取食的现象,在那里,造环海豚会制造环形泥羽来包围鱼群。在这里,我们首次记录了圭亚那海豚在巴西圣保罗州南部的卡纳内亚河口系统中的泥环觅食行为。在四次考察中,通过航拍镜头共记录了 11 条海豚的这种行为。这些发现扩大了我们对该物种行为可塑性的了解,并以鲸目动物泥环取食行为的现有记录为基础。

Eve Caroline Southward (1930–2023) was a multi-talented scientist, motivated by her curiosity and love of nature. Since she was never paid as a scientist, Eve was an amateur, in the best sense of the word. She was highly proficient at transmission electron microscopy and made lasting contributions to polychaete taxonomy, morphology and ecology. Eve was internationally respected, especially for her studies on the Siboglinidae, mouthless and gutless tubeworms (formerly called Pogonophora) that are found worldwide in the deep-sea. She described how the siboglinids obtained nutrition from symbiotic, sulphur-oxidising bacteria and described similar symbiotic relationships in several bivalve species. Eve wrote over 140 scientific publications and described 56 new benthic species, 47 being mouthless and gutless ‘pogonophores’. Eve assisted her husband Alan Southward in starting broad-scale intertidal surveys around the British Isles and Northwest Europe. These surveys formed the foundation for the time-series, later continued by others, that allowed assessments of the influence of climatic fluctuations, using intertidal rocky shore biota as indicators. Eve contributed, with Alan, to what became a 50-year study describing the long-term effects on intertidal communities of the oil pollution and excessive dispersant use resulting from the Torrey Canyon oil spill in 1967. Eve also co-wrote the Linnaean Society Synopsis on Echinoderms of the British Isles and helped complete unpublished work by Alan Southward and others on barnacle taxonomy.
夏娃-卡罗琳-索斯沃德(1930-2023 年)是一位多才多艺的科学家,她对大自然充满好奇和热爱。作为一名科学家,伊芙从未获得过报酬,因此从最好的意义上来说,她是一名业余爱好者。她精通透射电子显微镜,在多毛目动物分类学、形态学和生态学方面做出了不朽的贡献。伊芙在国际上备受尊敬,尤其是她对深海无口无肠管虫(原名 Pogonophora)的研究。她描述了 Siboglinids 如何从硫氧化共生细菌中获取营养,并描述了几种双壳类动物的类似共生关系。伊芙撰写了 140 多篇科学论文,描述了 56 种新的底栖生物,其中 47 种是无口无肠的 "pogonophores"。伊芙协助她的丈夫艾伦-索斯沃德(Alan Southward)在不列颠群岛和西北欧开始了大规模的潮间带调查。这些调查为后来由其他人继续进行的时间序列奠定了基础,从而可以利用潮间带岩岸生物群作为指标,评估气候波动的影响。伊芙与艾伦一起参与了一项长达 50 年的研究,该研究描述了 1967 年托雷峡谷石油泄漏造成的石油污染和过度使用分散剂对潮间带生物群落的长期影响。夏娃还与他人合作撰写了林奈学会关于不列颠群岛棘皮动物的提纲,并帮助完成了艾伦-索斯沃德(Alan Southward)等人未发表的藤壶分类工作。

This study describes the presence of the royal cucumber Parastichopus regalis (Cuvier, 1817) in The Natural Park of Ria Formosa (NPRF), Portugal. A single individual was observed during a monitoring scuba dive at a depth of 3 m inside this shallow mesotidal lagoon. The most plausible explanation for this occurrence is attributed to the rejection by trawlers when returning to their home port from their fishing grounds. This marine species has a deeper distribution outside the lagoon and is commonly captured as by-catch and subsequently discarded. This study also alerts us to the growing presence of non-indigenous species and the emergent threat of new invasions, highlighting the need to adopt biosecurity measures, like good practices for fishers when dealing with discards to avoid new species introductions in this fragile coastal marine habitat.
本研究描述了葡萄牙福尔摩沙岛自然公园(NPRF)中皇家黄瓜 Parastichopus regalis(Cuvier,1817 年)的存在。在该浅潮间带泻湖内 3 米深处进行的一次水肺潜水监测中,观察到了一只个体。出现这种情况的最合理解释是拖网渔船从渔场返回母港时将其拒之门外。这种海洋物种在环礁湖外分布较深,通常作为副渔获物被捕获,随后被丢弃。这项研究还提醒我们注意非土著物种的日益增多和新物种入侵的威胁,强调有必要采取生物安全措施,如渔民在处理丢弃物时的良好做法,以避免在这一脆弱的沿海海洋生境中引入新物种。

Lough Hyne (LH) Marine Nature Reserve in Ireland is a globally recognised biodiversity hotspot that hosts mesophotic-like communities in shallow water, however, major changes have occurred to most of the rocky cliff (>6 m) communities in one or more events between 2010 and 2015. To provide insights into these changes, we compared the sponge assemblage composition on the undersides of different sized, shallow (<1 m) subtidal boulders between 2000 and 2022 at two sites in LH. We also measured sponge species richness at seven sites in 2018. We found that unlike earlier reports from the deeper subtidal reef sponge assemblages, there was no evidence for changes in sponge assemblage composition on the undersides of boulders at either site. We also found high levels of sponge species richness at all seven sites sampled in 2018. We did find differences in sponge assemblages between sites and for different boulder sizes, which we propose is a result of site-specific environmental conditions and disturbance and size–area relationships. Since we found no changes in the shallow subtidal sponge assemblages between 2000 and 2022, our results support the hypothesis that changes to the deeper subtidal sponge assemblages at LH are driven by local processes associated with deeper water in LH, potentially related to the seasonal oxythermocline that forms within LH. Given the national and global importance of LH, understanding the drivers of change is critical to determine if management actions can prevent any future alterations to the LH sponge assemblages and support wider mesophotic community management.
爱尔兰海恩湖(Lough Hyne,LH)海洋自然保护区是全球公认的生物多样性热点地区,这里的浅水区拥有类似中生代的群落,然而,在 2010 年至 2015 年期间的一次或多次事件中,大部分岩石悬崖(6 米)群落发生了重大变化。为了深入了解这些变化,我们比较了 2000 年至 2022 年期间 LH 两个地点不同大小、浅滩(1 米)潮下巨石底部的海绵群落组成。我们还测量了 2018 年七个地点的海绵物种丰富度。我们发现,与之前有关潮下暗礁海绵组合的报告不同,没有证据表明这两个地点巨石底部的海绵组合组成发生了变化。我们还发现,2018 年采样的七个地点的海绵物种丰富度都很高。我们确实发现不同地点和不同大小巨石上的海绵组合存在差异,我们认为这是由于特定地点的环境条件以及干扰和大小面积关系造成的。由于我们发现 2000 年至 2022 年期间浅海潮下带海绵群落没有发生变化,我们的研究结果支持这样的假设,即 LH 深海潮下带海绵群落的变化是由与 LH 深水区相关的局部过程驱动的,可能与 LH 内形成的季节性温跃层有关。鉴于 LH 在国家和全球的重要性,了解变化的驱动因素对于确定管理行动是否能防止 LH 海绵群落在未来发生任何变化并支持更广泛的中层生物群落管理至关重要。

Ergasilid copepods represent one of the commonest groups of fish parasites in Brazil. Within Ergasilidae, three genera share a peculiar latching mechanism on the antenna that completely encircles the gill filament, one of which is Acusicola Cressey, 1970. During a survey of estuarine fish from the Brazilian Amazon Coast, a new species of Acusicola was found on the gills of the largescale foureyes Anableps anableps (Linnaeus, 1758) (Actinopterygii: Anablepidae) in São Marcos Bay, State of Maranhão. Acusicola rochai n. sp. can be distinguished from its closest congeners mainly by three protrusions on the dorsal surface of third and fourth pedigerous somites, and by smooth interpodal plates. This work is the first report of a parasitic copepod infesting a fish from Anablepidae and, consequently, the host An. anableps. The existing dichotomous key proposed for the genus Acusicola includes only ten species, excluding the eight species subsequently described. Therefore, in the present work, a new dichotomous key is provided based on reliable and well-documented features.

麦角桡足类是巴西最常见的鱼类寄生虫之一。在 Ergasilidae 中,有三个属的触角上都有一个奇特的闩锁机制,可以完全环绕鳃丝,其中一个属是 Acusicola Cressey,1970 年。在对巴西亚马孙河沿岸的河口鱼类进行调查期间,在马拉尼昂州圣马科斯湾的大型胭脂鱼 Anableps anableps (Linnaeus, 1758) (Actinopterygii: Anablepidae) 的鳃上发现了一种 Acusicola 新种。Acusicola rochai n. sp.主要通过第三和第四节背板上的三个突起以及光滑的节间板与其近缘种进行区分。这是首次报道寄生于 Anablepidae 鱼类的桡足类,因此也是寄主 Anableps 的桡足类。现有的 Acusicola 属二分检索表只包括 10 个物种,不包括后来描述的 8 个物种。因此,本研究根据可靠和有据可查的特征,提供了一个新的二分检索表。

Function of maxillipeds and first oostegites in bopyrid isopods inferred from behavioural observations of Bopyrus crangorum infesting Palaemon serrifer 通过观察蟋蟀等脚类动物侵扰蚕蛹的行为,推断栉水母等脚类动物的上鳃和第一鳃的功能

The morphology of female bopyrids is adapted to parasitism, but understanding the function of their thoracic and mouth appendages is hindered by their small size and cryptic lifestyle, limiting detailed examination. This study aimed to clarify the function of the first oostegites and maxillipeds in bopyrid isopods infesting the branchial chamber of caridean shrimp through behavioural observations and morphological examination. We tested whether the movement of these structures was exclusive to ovigerous female parasites during brood ventilation. The results revealed that the beating of the maxillipeds and flapping of the first oostegites were not restricted to ovigerous females. However, the frequency of these movements was significantly higher in ovigerous females than in non-ovigerous females. The frequency of maxilliped beating increased with embryonic development, whereas that of flapping the first oostegites exhibited the opposite trend. Microscopic observation using dye showed that the movements of the maxillipeds and the first oostegites expelled residual dye from the female brood chamber through the dorsal surface or beneath the first oostegites. The dye was then transported by the water current generated by the scaphognathite of the host shrimp. These findings suggest that these structures not only facilitate ventilation but also serve as a grooming mechanism for female parasites, which is critical for embryonic survival. The results of the present study represent the first observation of embryo grooming in bopyrid isopods. This study also provides new information on the functional morphology of bopyrid isopods, which is important for understanding their ecological dynamics and adaptation to parasitism.

雌性栉水母的形态适应寄生,但由于其体型较小,生活方式隐蔽,限制了对其胸部和口部附肢功能的详细检查。本研究旨在通过行为观察和形态学检查,弄清寄生在卡氏对虾鳃腔内的栉水母等脚类动物的第一口附肢和上颚附肢的功能。我们测试了这些结构的运动是否为卵生雌性寄生虫在育雏通风期间所独有。结果发现,上颚的跳动和第一节口的拍打并不局限于卵生雌虫。然而,有卵雌虫的这些运动频率明显高于无卵雌虫。随着胚胎的发育,上唇跳动的频率增加,而拍打第一节口的频率则呈现出相反的趋势。利用染料进行的显微观察表明,上鳃和第一节口的运动会将残留染料从雌性育雏室的背面或第一节口下方排出。然后,染料被宿主虾的鳞栉产生的水流带走。这些研究结果表明,这些结构不仅有利于通风,还可作为雌性寄生虫的梳理机制,这对胚胎的存活至关重要。本研究结果是首次观察到栉水母等脚类动物的胚胎梳理机制。本研究还提供了有关栉水母等脚类动物功能形态的新信息,这对了解其生态动态和对寄生的适应性非常重要。

Saccular otoliths (sagittae) have long been shown to be species-specific and exhibit inland geospatial intra- and interpopulation morphological differences with variations in environmental conditions. Here, we analysed inland and outland geospatial variations in sagittae shape, length (Lo), width (Wo), perimeter (Po), and area (Ao), and fluctuating asymmetry (FA) in Chelon auratus males and females collected from Ghar El Melh (Tunisia) and Etoile Bay (Mauritania) stations to assess whether sagittae shape and morphometry differ between these two niches having different environmental conditions. At the intrapopulation level, a significant otolith shape asymmetry was observed between left and right and left–left and right–right otoliths among males and females of the Ghar El Melh (Tunisia) population and a significant symmetry among those of the Etoile Bay (Mauritania) population. At the interpopulation level, a significant asymmetry was found between left and right otoliths' shape among males and females of the two populations. Besides, a discriminant function analysis of otoliths' contour shape separated left and right otoliths among males and females at the intra- and interpopulation levels and also separated those of the two populations. Moreover, differential significant asymmetry in Lo, Wo, Po, and Ao between left and right otoliths was observed among males and females at the intra- and interpopulation levels. Therefore, the geospatial variations in environmental conditions between the two ecological niches effectively induced differences in otolith morphology. These significant asymmetries were discussed in terms of FA caused by environmental stress conditions resulting from variations in abiotic factors between the two ecological niches.
很早以前就有研究表明,囊状耳石(sagittae)具有物种特异性,并随着环境条件的变化而表现出种群内和种群间的内陆地理空间形态差异。在此,我们分析了采集自突尼斯加尔梅勒(Ghar El Melh)站和毛里塔尼亚埃托尔湾(Etoile Bay)站的螯龙雄性和雌性的矢状突形状、长度(Lo)、宽度(Wo)、周长(Po)和面积(Ao)以及波动不对称性(FA)的内陆和内陆地理空间差异,以评估这两个具有不同环境条件的种群之间的矢状突形状和形态是否存在差异。在种群内水平,Ghar El Melh(突尼斯)种群的雄性和雌性耳石之间存在显著的左右不对称和左右对称,而 Etoile Bay(毛里塔尼亚)种群的雄性和雌性耳石之间存在显著的对称。在种群间水平,两个种群的雄性和雌性耳石的左右形状明显不对称。此外,通过对耳石轮廓形状的判别函数分析,在种群内和种群间水平上,雄性和雌性耳石的左侧和右侧耳石被区分开来,两个种群的雄性和雌性耳石也被区分开来。此外,在种群内和种群间水平上,雄性和雌性耳石的Lo、Wo、Po和Ao在左右耳石之间存在差异显著的不对称性。因此,两个生态位之间环境条件的地理空间差异有效地诱导了耳石形态的差异。这些明显的不对称现象被认为是由于两个生态位之间非生物因素的变化所导致的环境压力条件引起的。

We investigated how environmental conditions translate into reproductive success or failure in Aurelia aurita from the medusa to the polyp life stage. This study examined how: (i) settlement success and development of planula larvae and polyps vary across the year, (ii) the role of temperature in determining the successful settlement of larvae and growth of polyps, and (iii) the influence of maternal provisioning in the successful settlement of larvae and growth of polyps. Medusae were collected monthly from February to December 2019 from Horsea Lake, UK. Planula larvae were settled in conditions mimicking the in situ temperature and salinity of collection. For the individual treatments, planula collected in August settled most rapidly. Early development rates (<8 tentacles) were significantly higher than later growth rates (>8 tentacles) and were positively correlated with temperature, unlike later growth rates. Planula length, used as an indicator of maternal provisioning, varied significantly across the year. In July 2019, a high temperature anomaly coincided with an increased time spent by planula larvae in the water column. Increasing temperatures past thermal limits through the increasing occurrence of temperature anomalies is likely to be detrimental to larval settlement and indirectly to the replenishment of temperate polyp populations.
我们研究了环境条件是如何转化为 Aurelia aurita 从触角到息肉生命阶段的繁殖成败的。这项研究考察了(i) 介壳虫幼虫和多角体的定居成功率和发育在一年中的变化,(ii) 温度在决定幼虫成功定居和多角体生长中的作用,以及 (iii) 母体供给在幼虫成功定居和多角体生长中的影响。2019年2月至12月期间,每月从英国霍尔沙湖采集鳉鱼。栉水母幼虫在模拟采集时的原地温度和盐度条件下沉降。在各处理中,8月份采集的栉水母沉降速度最快。早期发育率(8触手)明显高于后期生长率(8触手),并且与温度呈正相关,与后期生长率不同。作为母体供养指标的触角长度在一年中变化很大。2019 年 7 月,气温异常升高的同时,浮游幼虫在水体中停留的时间也增加了。通过增加温度异常的发生率来提高温度,使其超过热极限,很可能不利于幼虫的沉降,并间接影响温带多角体种群的补充。

Egg masses from an unknown mollusc have been found in South-West Iceland since 2020, but it was not until September 2023 that the adult organism was collected. Morphological analysis of both adults and egg masses pointed towards the identification of the species as Melanochlamys diomedea. This was further confirmed through DNA analyses using COI, H3, and 16S rRNA markers, which established the presence of a new non-indigenous species in the North Atlantic. Members of the genus Melanochlamys have predominantly been found in the Indo-Pacific basin and the Pacific Ocean, with only one species known to exist across the Madeira Islands, Canary Islands, and Cape Verde in the Atlantic. The known distribution range of M. diomedea extends from Alaska to California on the Pacific side of North America, where it typically inhabits sandy-muddy areas of the littoral in the tidal zone and below. It is not known how the species arrived in Iceland. However, maritime transport through either ballast water or biofouling is being considered as the most likely mode of dispersal.
自 2020 年以来,冰岛西南部发现了一种未知软体动物的卵块,但直到 2023 年 9 月才采集到成体。对成体和卵块的形态分析表明,该物种被鉴定为 Melanochlamys diomedea。利用 COI、H3 和 16S rRNA 标记进行的 DNA 分析进一步证实了这一点,从而确定了北大西洋存在一个新的非本土物种。Melanochlamys属的成员主要分布在印度洋-太平洋盆地和太平洋,已知只有一个物种分布在大西洋的马德拉群岛、加那利群岛和佛得角。蓑鲉的已知分布范围从北美洲太平洋一侧的阿拉斯加延伸到加利福尼亚,通常栖息在潮汐带及以下的沿岸沙泥地区。目前尚不清楚该物种是如何到达冰岛的。不过,通过压舱水或生物污损进行海上运输被认为是最可能的传播方式。

Polynesia is a hotspot for marine biodiversity in the South Pacific Ocean, yet the distribution of many invertebrate taxa in this region is still often poorly assessed. Information on the diversity and phylogeography of sponges in particular remains limited in spite of their importance for coral reef ecosystems. Recent expeditions to the island group of Wallis and Futuna enabled the first larger-scale assessment of the Wallis Island sponge fauna, resulting in the molecular identification of 82 unique Molecular Operational Taxonomic Units (MOTUs) from 339 sponge samples based on 28S C-region rDNA and CO1 mtDNA data. Faunal comparisons with both adjacent archipelagos and more distant Indo-Pacific regions were predominantly based on the MOTUs obtained from Wallis Island ecoregions, and suggest high levels of endemism of sponges in Wallis and Futuna, corroborating previous data on the biodiversity of sponges and other marine phyla in the South Pacific. The results of this molecular taxonomic survey of the Wallis and Futuna sponge fauna aim to lay solid foundations for a sustainable ‘Blue Economy’ in Wallis and Futuna for the conservation of their local coral reefs.
波利尼西亚是南太平洋海洋生物多样性的热点地区,但该地区许多无脊椎动物类群的分布情况往往还没有得到很好的评估。尽管海绵对珊瑚礁生态系统非常重要,但有关海绵多样性和系统地理学的信息仍然有限。最近对瓦利斯群岛和富图纳群岛的考察首次对瓦利斯岛海绵动物群进行了较大规模的评估,根据 28S C 区域 rDNA 和 CO1 mtDNA 数据,从 339 个海绵样本中分子鉴定出 82 个独特的分子操作分类单元(MOTU)。与邻近群岛和更遥远的印度洋-太平洋地区的动物比较主要基于从瓦利斯岛生态区域获得的分子操作分类单元,结果表明瓦利斯群岛和富图纳群岛的海绵具有高度的地方特有性,证实了之前关于南太平洋海绵和其他海洋门类生物多样性的数据。瓦利斯群岛和富图纳群岛海绵动物群分子分类调查的结果旨在为瓦利斯群岛和富图纳群岛的可持续 "蓝色经济 "奠定坚实的基础,以保护当地的珊瑚礁。
