Abstract

A systematic study of the interaction of hydrobiological, hydrochemical, hydrological, and hydrophysical processes that occur in the ecosystem of the Vistula Lagoon (VL) of the Baltic Sea has been carried out using mathematical modeling and taking into account the processes in the active layer of bottom sediments (BSs). The features of the dynamics of nitrogen and phosphorus compounds, the turnover time, and the components of the balance of compounds of biogenic elements in the VL ecosystem, as well as the degree of their temporal variability, have been analyzed. It is shown that the variability of nitrogen and phosphorus compounds in the aquatic environment increases in spring and autumn periods. This is due to an increase in river flow into the lagoon and an increase in the level of external biogenic load on the water area of the VL. Model calculations of matter fluxes allow us to state that the inputs of dissolved organic and suspended matter into the lagoon from external sources and the removal to the Baltic Sea are important processes that significantly affect their content in the VL ecosystem. It has been established that under strong winds the process of sedimentation of suspensions can be largely blocked, and the intensity of BS resuspension can increase significantly. An analysis of the main qualitative and quantitative features of the nature of the temporal dynamics of the DON and DOP turnover times, as well as the mineral compounds of nitrogen and phosphorus, indicates a close conjugation of the processes of transformation of dissolved organic and inorganic substances in the water of the VL. A quantitative assessment of the processes of consumption and excretion of compounds of biogenic elements by different groups of aquatic organisms has been performed, and the important role of heterotrophic bacterioplankton and protozoa in the processes of transformation of compounds of nutrients in the VL ecosystem has been shown. The model can be used for scenario modeling and analyzing possible changes in the VL ecosystem under changing climatic and anthropogenic conditions.

摘要利用数学模型并考虑到底层沉积物（BSs）活动层的过程，对波罗的海维斯瓦泻湖（VL）生态系统中发生的水生物、水化学、水文和水物理过程的相互作用进行了系统研究。研究分析了 VL 生态系统中氮化合物和磷化合物的动态特征、周转时间、生物源元素化合物平衡的组成部分及其时间变化程度。结果表明，水生环境中氮化合物和磷化合物的变化在春季和秋季增加。这是由于流入泻湖的河水流量增加，以及 VL 水域的外部生物负荷水平提高所致。通过对物质通量的模型计算，我们可以得出这样的结论：从外部输入泻湖的溶解有机物和悬浮物以及向波罗的海的清除是对 VL 生态系统中物质含量产生重大影响的重要过程。已经证实，在强风的作用下，悬浮物的沉积过程会在很大程度上受阻，BS 再悬浮的强度也会显著增加。对 DON 和 DOP 以及氮和磷的矿物化合物的时间动态性质的主要定性和定量特征的分析表明，VL 水体中溶解的有机物和无机物的转化过程密切相关。对不同种类水生生物消耗和排泄生物元素化合物的过程进行了定量评估，结果表明，在 VL 生态系统中，异养浮游细菌和原生动物在营养物质化合物的转化过程中发挥着重要作用。该模型可用于情景建模，分析在不断变化的气候和人为条件下 VL 生态系统可能发生的变化。

Abstract

Using scanning electron microscopy, 33 morphotypes of stomatocysts of Chrysophyceae are found in the plankton of the reservoirs, lakes, and rivers of the mountain–forest zone of the Southern Urals; 8 of them are noted in Russia for the first time, and 1 is described as new to science. The description of each morphotype is accompanied by a SEM micrography, geographical location, and environmental characteristics. Unornamented stomatocysts with a spherical form are predominant in abundance in plankton. Ornamented stomatocysts with a spherical form are predominant in diversity in plankton. The maximum diversity of stomatocysts is observed in spring and in autumn. The high diversity of stomatocysts indicates a significant diversity of golden algae in the Southern Ural region.

Abstract

The results of an experiment on the oral exposure of polychlorinated biphenyl (PCB) 118 into the zebrafish Danio rerio (Hamilton, 1822) (F0) with food at calculated doses of 5, 20, and 80 μg/individuals are presented. In the first generation F1, there is a decrease in survival rate and a shift in the sex ratio, predominantly towards females. In the second generation F2, the same effects are noted as in F1, but they are not as pronounced. It has been hypothesized that the effects seen in the F2 generation may be caused by epigenetic mechanisms, which are still poorly understood. It is possible that the feminization of animal populations and a decrease in their survival rate are very strong factors in reducing the populations of living organisms, including humans, especially near sites of distribution of PCBs. It is necessary to study epigenetic mechanisms in order to develop measures to eliminate and prevent problems with the biotic degradation and depopulation of fish exposed to PCBs in the sites that arise as a result of the improper disposal of electrical engineering waste containing PCBs.

摘要本文介绍了斑马鱼 Danio rerio（Hamilton，1822 年）口服多氯联苯（PCB）118（F0）的实验结果，食物的计算剂量为 5、20 和 80 微克/个体。在第一代 F1 中，存活率下降，性别比例发生变化，主要偏向雌性。在第二代 F2 中，发现了与 F1 相同的影响，但并不明显。据推测，F2 代中出现的影响可能是由表观遗传机制造成的，但人们对这种机制还不太了解。动物种群的雌性化和存活率的下降可能是导致生物种群（包括人类）减少的重要因素，尤其是在多氯联苯的分布地点附近。有必要对表观遗传学机制进行研究，以便制定措施，消除和防止由于含有多氯联苯的电气工程废物处置不当而造成的生物退化和鱼类接触多氯联苯后数量减少的问题。

Abstract

Materials determining the possible pathways of Arctic zone colonization by representatives of thermophilic ichthyofauna are presented. The previously proposed hypothesis that the fish of the thermophilic complex that lived in the White Sea basin during the Subboreal period (sterlet, blue bream, common rudd, white-eye bream, and asp) and were considered extinct during the subsequent cooling in the Subatlantic period, adapted to changed conditions, stayed in particular areas of their range, and became part of the modern ichthyofauna in limited numbers have been elaborated and confirmed. The possible pathways of spontaneous introduction of the Caspian thermophilic species, white-eye bream, and asp to the Northern Dvina basin are considered. Populations of rudd and blue bream, rare thermophilic species for the region, have been detected and studied in the lakes of the Kenozersky National Park. Rudd, a relict species of the Holocene thermal maximum, was previously recorded only in several floodplain lakes of the middle reaches of the Northern Dvina River. The Kenozero population of rudd is the first case of finding epresentatives of this species in the Onega River basin. Blue bream can be also considered a relict found in the territory of the region only in one lake system of the Kenozersky National Park and several small lakes of the Siysky State Nature Reserve.

摘要介绍了确定嗜热鱼类代表在北极地区定居的可能途径的材料。之前提出的假说得到了详细阐述和证实，即在亚寒带时期生活在白海盆地的嗜热复合鱼类（赤鲷、蓝鲷、普通鳕、白眼鲷和鳕鱼）在随后的亚大西洋时期的降温过程中被认为已经灭绝，但它们适应了变化的条件，停留在其分布范围的特定区域，并以有限的数量成为现代鱼类的一部分。考虑了里海嗜热鱼种、白眼鳊和asp自发引入北德维纳盆地的可能途径。在凯诺泽尔斯基国家公园的湖泊中发现并研究了该地区罕见的嗜热鱼种--大红鲂和青鳊的种群。白鲦鱼是全新世热量最高时期的孑遗物种，以前仅在北德维纳河中游的几个洪泛平原湖泊中有过记录。凯诺泽罗的鳊鱼种群是首次在奥涅加河流域发现该物种的代表。蓝鳊鱼也可以被认为是该地区的一种孑遗鱼，仅在凯诺泽尔国家公园的一个湖系和西伊斯基国家自然保护区的几个小湖泊中发现过。

Abstract

As a result of global warming, the average annual water temperature has significantly increased in the Upper Volga reservoirs. Warming and the subsequent deterioration of the oxygen regime has had a significant effect on most of the fish populations inhabiting temperate waters. This has led to changes in the population structure of many fish species. Phenomena such as the disappearance or a sharp decline in the abundance of cold-water species (European smelt, vendace, burbot, and pike) in the Rybinsk Reservoir coincide with the period of warming. The disappearance of European smelt in the Rybinsk Reservoir and the favorable temperature regime has contributed to the appearance and rapid increase in the abundance of a Caspian invader, the Black Sea sprat, which has occupied the empty niche of the European smelt and became the dominant species in the pelagic zone of the Upper Volga reservoirs. Warming has resulted in a decrease in the abundance and the growth rate of burbot and pike. Climate warming has had an indirect effect on many species through oxygen deficiency or the transformation of the forage base (ruff, zander, perch, and roach), which has also led to a decrease in abundance and the growth rate.

摘要由于全球变暖，伏尔加河上游水库的年平均水温明显升高。气候变暖以及随之而来的氧气系统恶化对栖息在温带水域的大多数鱼类种群产生了重大影响。这导致许多鱼类的种群结构发生变化。雷宾斯克水库中的冷水鱼种（欧洲胡瓜鱼、鲑鱼、鳕鱼和梭子鱼）消失或数量急剧下降等现象与气候变暖时期相吻合。欧洲胡瓜鱼在雷宾斯克水库的消失和有利的温度条件促成了里海入侵者黑海鲱的出现和数量的迅速增加，黑海鲱占据了欧洲胡瓜鱼的空位，成为伏尔加河上游水库水层区的主要物种。气候变暖导致大菱鲆和梭子鱼的数量和生长速度下降。气候变暖通过缺氧或觅食基础的改变对许多物种产生了间接影响（胭脂鱼、塘鲉、鲈鱼和鳊鱼），这也导致了数量和生长率的下降。

Abstract

The presence of a complex of biologically active steroid compounds (BASCs)—hydrocortisone, corticosterone, progesterone, testosterone, and estrogens (vertebrate hormones)—in invertebrate hydrobionts of different phylogenetic levels has been revealed in experiments. The features of the quantitative content of BASCs in different organs/tissues of hydrobionts and their changes at different stages of development are shown. The level of BASCs in organisms or their organs is largely due to their own steroidogenesis, but organisms can accumulate exogenous steroid compounds. The adaptive role of BASCs in some invertebrates in changing conditions of the aquatic environment has been found. The similarity of the concentration of steroid compounds in different groups of bionts leads to the idea of a certain “physiological constant” of this complex of compounds in all organisms.

摘要通过实验发现，在不同系统发育水平的无脊椎动物水螅中存在生物活性类固醇化合物（BASCs）复合物--氢化可的松、皮质酮、孕酮、睾酮和雌激素（脊椎动物激素）。实验显示了水螅不同器官/组织中 BASCs 的定量含量特征及其在不同发育阶段的变化。生物体或其器官中的 BASCs 水平主要是由其自身的类固醇生成所致，但生物体也可积累外源类固醇化合物。研究发现，一些无脊椎动物体内的 BASCs 对水生环境条件的变化具有适应作用。不同类群仿生生物体内类固醇化合物浓度的相似性导致人们认为，所有生物体内的这种复合化合物都有一定的 "生理常数"。

Abstract

Study was conducted to determine the impact of current velocity on density and abundance of benthic macroinvertebrate fauna in an Indian Himalayan River, the Ramganga. The samples were collected at 8 different stations from headwater to mouth (S1 to S8) during October 2014 to March 2015. One-time intensive sampling (20 quadrates per station) was performed in the dry-period. The benthic macroinvertebrate samples were collected to all possible current velocities at each station from 7 cm to 55 cm depth. and they were categorized in to 5 categories of current velocity; extreme low (type I, 0–15 cm s^–1), low (type II, 15–30 cm s^–1), mild (type III, 30–45 cm s^–1), moderate (type IV, 45–60 cm s^–1) and high (type V, >60 cm s^–1). The standard methods were used to collect invertebrate samples and identify at family level. The total mean density of invertebrate fauna decreased from type I (616 ind. × m^–2) to type II (358.87 ind. × m^–2), and increased to type III (925.25 ind. × m^–2), but again decreased to type IV (539.37 ind. × m^–2) and type V (85.25 ind. × m^–2). The mild velocity (type III) was most important for providing maximum density and richness. The total density (ind. × m^–2) between every two current velocity types was not found significantly different except current velocity type V-I. Total 34 taxa were observed among all the stations, maximum number (22) taxa were found in type III, while lowest number (8) in type IV. However, out of 34 taxa, Glossoscolecidae was most abundant in type I velocity, Simulidae in type II, Leptoceridae in type III and V, while Psephenidae in type IV. Similarly, PCA also suggested the characteristics taxa at each velocity type.

摘要研究旨在确定水流速度对印度喜马拉雅山脉河流拉姆甘加河底栖大型无脊椎动物密度和丰度的影响。样本于 2014 年 10 月至 2015 年 3 月期间在从上游到河口（S1 至 S8）的 8 个不同站点采集。在枯水期进行了一次性密集采样（每个站点 20 个四分点）。底栖大型无脊椎动物样本在每个站点从 7 厘米到 55 厘米深度的所有可能流速下采集，并按流速分为 5 类：极低（I 类，0-15 厘米 s-1）、低（II 类，15-30 厘米 s-1）、轻（III 类，30-45 厘米 s-1）、中（IV 类，45-60 厘米 s-1）和高（V 类，60 厘米 s-1）。采用标准方法采集无脊椎动物样本并进行科级鉴定。无脊椎动物总平均密度从 I 型（616 ind. × m-2）下降到 II 型（358.87 ind. × m-2），然后上升到 III 型（925.25 ind. × m-2），但又下降到 IV 型（539.37 ind. × m-2）和 V 型（85.25 ind. × m-2）。轻度速度（III 型）对提供最大密度和丰富度最为重要。除 V-I 型流速外，每两种流速之间的总密度（指数×米-2）均无显著差异。各站共观察到 34 个分类群，其中类型 III 的分类群数量最多（22 个），类型 IV 的分类群数量最少（8 个）。然而，在 34 个分类群中，I 型流速下的 Glossoscolecidae 种类最多，II 型流速下的 Simulidae 种类最多，III 型和 V 型流速下的 Leptoceridae 种类最多，而 IV 型流速下的 Psephenidae 种类最少。同样，PCA 也显示了各速度类型的特征类群。

One-time intensive sampling (20 quadrates per station) was performed in the dry-period. The benthic macroinvertebrate samples were collected to all possible current velocities at each station from 7 cm to 55 cm depth. and they were categorized in to 5 categories of current velocity; extreme low (type I, 0–15 cm s<sup>–1</sup>), low (type II, 15–30 cm s<sup>–1</sup>), mild (type III, 30–45 cm s<sup>–1</sup>), moderate (type IV, 45–60 cm s<sup>–1</sup>) and high (type V, >60 cm s<sup>–1</sup>). The standard methods were used to collect invertebrate samples and identify at family level. The total mean density of invertebrate fauna decreased from type I (616 ind. × m<sup>–2</sup>) to type II (358.87 ind. × m<sup>–2</sup>), and increased to type III (925.25 ind. × m<sup>–2</sup>), but again decreased to type IV (539.37 ind. × m<sup>–2</sup>) and type V (85.25 ind. × m<sup>–2</sup>). The mild velocity (type III) was most important for providing maximum density and richness. The total density (ind. × m<sup>–2</sup>) between every two current velocity types was not found significantly different except current velocity type V-I. Total 34 taxa were observed among all the stations, maximum number (22) taxa were found in type III, while lowest number (8) in type IV. However, out of 34 taxa, Glossoscolecidae was most abundant in type I velocity, Simulidae in type II, Leptoceridae in type III and V, while Psephenidae in type IV. Similarly, PCA also suggested the characteristics taxa at each velocity type.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"11 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract

The report provides new data on Vaucheria vipera Blum, one of the rarest collected marine species. In 2023, V. vipera was discovered in the littoral zone of the Unskaya Inlet of the White Sea. The record is considered first in Russia and the Arctic Ocean. The study of the morphology of specimens from the White Sea allowed to expand the morphological range of the species in terms of the maximum dimensions of oogonia, oospores, and antheridia. The work also pays attention to the basal septa that separate short branches bearing the gametangia. Based on the morphology of the gametangia, it is proposed to transfer this species to the section Woroninia.

摘要报告提供了有关 Vaucheria vipera Blum 的新数据，这是收集到的最稀有的海洋物种之一。2023 年，V. vipera 在白海 Unskaya Inlet 沿岸地区被发现。该记录被认为是俄罗斯和北冰洋的首次记录。通过对白海标本形态的研究，扩大了该物种的形态范围，包括卵原细胞、卵孢子和花药的最大尺寸。这项工作还关注了基部隔膜，该隔膜将带有配子器的短枝分开。根据配子器的形态，建议将该物种归入 Woroninia 节。

Abstract

The current state of the concept of the health of aquatic ecosystems and the main methods and technologies (mainly instrumental) for its assessment are briefly considered. The data obtained during the study of the health of ecosystems of several recreational areas of the Black Sea, the eastern part of the Gulf of Finland, several channels of the Volga delta are considered. An operational assessment of the health of ecosystems was carried out using innovative biomonitoring technology by testing the health of adult bivalve mollusks living in them by the functional load method based on the analysis of their heart rate, measured using the BioArgus bioelectronic fiber-optic system. It has been established that the functional state of mollusks can serve as an indicator of excess pollution of coastal waters by objects that discharge insufficiently treated domestic wastewater from their local treatment facilities, including household wastewater. It is concluded that, taking into account the rather high rapidity and ease of use, this technology can be effectively used to solve the problems of screening studies and early diagnostics of the state of aquatic ecosystems as well as serve as an information basis for developing regionally oriented, science-based environmental management decisions. Recently, the BioArgus automated system was metrologically type-certified (Order of Rosstandart No. 2702 dated 10/27/2022 on the approval of types of measuring instruments). The latter opened up the legal right to use this measuring system in urban water supply and sanitation enterprises, as well as to develop various regional certified methods and technologies for assessing the ecological state (health) of aquatic ecosystems, based on the use of BioArgus systems as measuring instrument.

摘要简要介绍了水生生态系统健康概念的现状及其评估的主要方法和技术（主要是仪器）。文中考虑了在对黑海、芬兰湾东部和伏尔加河三角洲几个水道的几个休闲区的生态系统健康状况进行研究期间获得的数据。利用创新的生物监测技术对生态系统的健康状况进行了实际评估，通过使用 BioArgus 生物电子光纤系统测量双壳软体动物的心率分析，采用功能负荷法对生活在生态系统中的成年双壳软体动物的健康状况进行了检测。研究表明，软体动物的功能状态可以作为沿海水域受到当地处理设施排放的未经充分处理的生活废水（包括家庭废水）过量污染的指标。结论是，考虑到该技术的快速性和易用性，它可以有效地用于解决筛选研究和早期诊断水生生态系统状况的问题，并可作为制定面向区域的、以科学为基础的环境管理决策的信息依据。最近，BioArgus 自动化系统通过了计量类型认证（关于计量仪器类型认证的俄罗斯标准局第 2702 号命令，日期为 10/27/2022 年）。这为在城市供水和卫生企业中使用该测量系统，以及在使用 BioArgus 系统作为测量仪器的基础上开发各种评估水生生态系统生态状态（健康）的区域认证方法和技术提供了合法权利。
