The Notch receptor is a pleiotropic signaling protein that translates intercellular ligand interactions into changes in gene expression via the nuclear localization of the Notch intracellular Domain (NICD). Using a combination of immunohistochemistry, RNA in situ, Optogenetics and super-resolution live imaging of transcription in human cells, we show that the N1ICD can form condensates that positively facilitate Notch target gene expression. We determined that N1ICD undergoes Phase Separation Coupled Percolation (PSCP) into transcriptional condensates, which recruit, enrich, and encapsulate a broad set of core transcriptional proteins. We show that the capacity for condensation is due to the intrinsically disordered transcriptional activation domain of the N1ICD. In addition, the formation of such transcriptional condensates acts to promote Notch-mediated super enhancer-looping and concomitant activation of the MYC protooncogene expression. Overall, we introduce a novel mechanism of Notch1 activity in which discrete changes in nuclear N1ICD abundance are translated into the assembly of transcriptional condensates that facilitate gene expression by enriching essential transcriptional machineries at target genomic loci.

ABSTRACT Yang, S.M. and Lee, J.K., 2024. Evaluating the geoengineering performance of a gravity multiblock quay wall and jet-grouting on marine clayey soils along the Korean coastline. Journal of Coastal Research, 40(4), 672–682. Charlotte (North Carolina), ISSN 0749-0208. Jet-grouting has been widely used as a ground improvement method in several fields of geoengineering, but most of the case studies have focused on embankments and excavations. This paper describes the performance of a gravity block-type quay wall in the southwest coast of Korea where the underlying soft clayey soils were improved by jet-grout columns. The scheme and properties of jet-grouting and the construction history and measured behavior of the wall-soil system are presented. A finite element analysis was conducted to estimate the settlement, lateral displacement, and horizontal earth pressure of the quay wall. The computed results compare well with the field data during and after construction. The effect of area replacement ratio, quantifying the degree of ground improvement, on the response of the quay walls was also investigated. The field and numerical results show that the jet-grout columns enhanced the performance of the block-type quay wall over soft soils.
ABSTRACT Yang, S.M. and Lee, J.K., 2024.韩国海岸线海洋粘土上的重力多块式码头墙和喷射灌浆的地质工程性能评估。Journal of Coastal Research, 40(4), 672-682.夏洛特（北卡罗来纳州），ISSN 0749-0208。喷射灌浆作为一种地基改良方法已被广泛应用于多个地质工程领域，但大多数案例研究都集中在路堤和开挖方面。本文介绍了韩国西南海岸重力砌块式码头墙的性能，该码头墙的下层软粘土是通过喷射灌浆柱改良的。文中介绍了喷射灌浆的方案和特性，以及墙土系统的施工历史和实测行为。对码头墙的沉降、侧向位移和水平土压力进行了有限元分析。计算结果与施工期间和施工后的实地数据比较吻合。此外，还研究了面积置换比（量化地面改良程度）对码头墙响应的影响。现场和数值结果表明，喷射灌浆柱增强了砌块式码头墙在软土上的性能。

ABSTRACT Mohale, H.P.; Jawahar, P.; Jayakumar, N.; Swapnil, N.; Kadam, R.V.; Prakash, P.; Oli, G.A., and Ravikumar, T., 2024. Fishery, biology, and dynamics of Parapenaeopsis maxillipedo (Alcock, 1905) off the SE coast of Tamil Nadu (India). Journal of Coastal Research, 40(4), 779–791. Charlotte (North Carolina), ISSN 0749-0208. The current study was carried out between September 2022 to September 2023 from SE coast of Tamil Nadu for Parapenaeopsis shrimp. This shrimp, estimated to rank third in shrimp production, landed as 2216, 2032, and 1704 kg from Thoothukudi, Mandapam, and Nagapattinam landing centers, respectively. The catch per unit effort was calculated to check the abundance of this species and ranged from 21.83 to 96.41 kg, averaging 46.33% in both years. The total length of males and females was observed in the range of 5.5 to 10.5 cm and 6.5 to 12.5 cm, respectively. Female shrimp attained first maturity at 6.5 cm, whereas male shrimp were 5.5 cm. The gonadosomatic index was calculated and found to be the highest (5.64–5.78) in March and September and the lowest in April and October for both years. The absolute fecundity for P. maxillipedo was recorded and ranged from 38,500 to 1,32,000 ova per female. The highest index of relative importance was observed in October and April for both male (57.04) and female (73.82) shrimp. To estimate von Bertalanffy's growth equation in P. maxillipedo, the asymptotic length and growth coefficient (K) growth parameters were combined for both sexes and analyzedas 13.55 cm and 1.5 y–1, respectively. The total mortality and natural mortality (M) were observed as 3.04 and 2.86 y–1, respectively. Hence, fishing mortality was 0.18 y–1, and the exploitation rate (E) was 0.06. The length at first catch per length (LC/L) and M/K values were calculated using the Y/R model as 0.52 and 1.2 for males and 0.48 and 1.3 for females, respectively. E was observed as 0.06, which was lower than the maximum E of 0.4, which showed that the P. maxillipedo fisheries along the SE coast of Tamil Nadu were at unexploited conditions.

ABSTRACT Amarasekara, K.; Perera, C.; Yatawara, M., and Jayasiri, H.B., 2024. Lesser-known species (Ipomoea imperati) from the Convolvulaceae family: First record from the Manalkaadu sand dunes of Jaffna, Sri Lanka. Journal of Coastal Research, 40(4), 803–808. Charlotte (North Carolina), ISSN 0749-0208. Coastal sand dunes are dynamic and fragile ecosystems found along some sandy shorelines. They are typically supported by a wide variety of specialized floral and faunal life. Coastal sand dunes are especially common in temperate coastal areas but are less abundant in tropical or subtropical coasts. A comprehensive study of flora in the Manalkaadu sand dune ecosystem was completed from August 2022 to May 2023, using 50-m × 5-m belt transects. The study area was divided into nine distinct locations for systematic sampling. Ipomoea imperati (Vahl) Griseb., a dicotyledonous flowering plant commonly known as fiddle-leaf morning-glory of the Convolvulaceae family, was recorded for the first time in the Manalkaadu sand dunes of the Northern Province in Sri Lanka during the study. Ipomoea imperati has smooth trailing stems that are covered with alternately arranged lanceolate, fleshy dark green leaves with a notched apex. Ipomoea imperati bloomed from September 2022 to March 2023 in the study area, and the funnel-shaped flowers were fused with white petals and yellow centers. In the area where it was discovered, the species withstood high substrate temperatures (about 29°C to 35°C), sand scouring, and moderate burial by accreted sand. Out of nine sampling locations, I. imperati was found in five locations. The plant density (two to six), plant percentage frequency (40% to 60%), Shannon Wiener diversity index (0.54 to 1.43), species evenness (0.50 to 0.90), and richness (2 to 5) were also analyzed. Thus, the density of I. imperati in five sampling locations was considered to be moderate, whereas the diversity was very low. It is designated as endangered in the National Red List 2020—Conservation Status of the Flora of Sri Lanka.

ABSTRACT Abir, T.M.; Das, T., and Ferdous, F., 2024. Building community resilience and adaptation to climate change: Integrating disaster risk reduction in the coastal regions of Bangladesh. Journal of Coastal Research, 40(4), 792–802. Charlotte (North Carolina), ISSN 0749-0208. Building community resilience is very significant in reducing climate shocks and disaster risk. There is some insufficiency in community resiliency among coastal communities of Bangladesh, so they are still suffering from disastrous events like cyclones, floods, riverbank erosion, heavy rain, salinity, and tidal surges. So, this study critically examined the impacts of disasters on coastal communities and how they can build their resilience to reduce disaster risk. This study emphasizes the local adaptation strategies for risk reduction and the barriers faced by the local coastal community that hinder disaster resilience. The study was conducted from November 2022 to March 2023. A mixed-method research approach was utilized to assess the situation. In order to gauge the resilience of the community, the study focused on social, economic, infrastructure, and institutional dimensions based on different established climate disaster resilience indexes and frameworks. Key informant interview and face-to-face interview methods were used for data collection. Findings showed that the main barrier to sustainable adaptation and community resilience is the poor socioeconomic conditions of the community in the study area. Lower rates of quality education, limited livelihood opportunities, lack of other resources, and repeated disastrous events cause poor socioeconomic situations for those communities. The results show that the area is highly dependent on agriculture and fishing, so there needs to be special consideration given to disaster tolerance cultivation. In addition, the collaboration of locally grounded adaptation solutions and technological solutions should be emphasized for sustainable adaptation and will be necessary to ensure sustainable livelihoods. The study suggests that policymakers prioritize social and institutional support in building community resilience to reduce disaster risk.
ABSTRACT Abir, T.M.; Das, T., and Ferdous, F., 2024.建设社区抗灾能力，适应气候变化：孟加拉国沿海地区的减灾一体化。Journal of Coastal Research, 40(4), 792-802.Charlotte (North Carolina), ISSN 0749-0208.建设社区抗灾能力对减少气候冲击和灾害风险意义重大。孟加拉国沿海社区的抗灾能力还存在一些不足，因此他们仍在遭受气旋、洪水、河岸侵蚀、暴雨、盐碱化和潮汐汹涌等灾难性事件的影响。因此，本研究批判性地考察了灾害对沿海社区的影响，以及他们如何增强自身的抗灾能力以降低灾害风险。本研究强调了当地减少风险的适应战略，以及当地沿海社区面临的阻碍抗灾能力的障碍。研究于 2022 年 11 月至 2023 年 3 月进行。研究采用了混合方法评估情况。为了衡量社区的抗灾能力，研究根据不同的既定气候灾害抗灾能力指数和框架，重点关注社会、经济、基础设施和机构等方面。数据收集采用了关键信息提供者访谈和面对面访谈的方法。研究结果表明，可持续适应和社区抗灾能力的主要障碍是研究地区社区的社会经济条件较差。较低的优质教育率、有限的谋生机会、其他资源的缺乏以及灾难性事件的反复发生，都造成了这些社区的社会经济状况不佳。研究结果表明，该地区高度依赖农业和渔业，因此需要特别考虑容灾能力的培养。此外，为实现可持续适应，应强调立足当地的适应解决方案与技术解决方案的合作，这对确保可持续生计十分必要。研究建议决策者在建设社区抗灾能力时优先考虑社会和机构支持，以降低灾害风险。

ABSTRACT Sun, Y.; Zhang, S.; Yang, S.; Zhou, W.; Cui, X., and Wu, Y., 2024. Review and analysis of electronic monitoring (EM) minimum standards for pelagic main fishing gear. Journal of Coastal Research, 40(4), 816–825. Charlotte (North Carolina), ISSN 0749-0208. Observer systems for monitoring and collecting catch information from pelagic fisheries are essential in ensuring the sustainable harvesting of pelagic fisheries resources. The emergence in recent years of electronic observers that rely on video surveillance is gradually becoming a complementary or alternative measure to human observers. Electronic observers' security and ease of use make full electronic monitoring (EM) of ocean-going fishing ships possible while ensuring complete data availability. The development and improvement of its standards are the keys to ensuring the large-scale application of EM. This paper summarizes and justifies the minimum standards for EM for pelagic fishing by analyzing the standards and current status of human observers, documenting the functions and applications of EM systems, comparing the monitoring capabilities of human observers and EM, and analyzing the characteristics of the three main fishing methods: purse seine, trawl, and longline, respectively, in terms of equipment platform technology, data collection, and data management. The development of EM standards can clarify the cost of the entire monitoring process, ensure the compliance and economics of EM, and achieve effective long-term monitoring of pelagic fishing.

ABSTRACT Engin, S.; Gurkan, S., and Taskavak, E., 2024. Cellular changes in liver tissue of adult common sole (Solea solea L. 1758) in the Aegean Sea, Turkey. Journal of Coastal Research, 40(4), 740–748. Charlotte (North Carolina), ISSN 0749-0208. In this study, cellular changes and biological indices in the liver tissue of the common sole, Solea solea (L. 1758), are investigated based on sex, size groups, and seasons. The specimens used in the study were obtained monthly between 2019 and 2020 from commercial trawlers and small scale–fishing operations in the fishing grounds of Izmir Bay, the Aegean Sea coast of Turkey. A total of 240 common sole fish (166 female, 66 male, 8 immature) were used in this study. In the obtained specimens, the male: female ratio was determined as 0.39:1 (χ2 = 33.19; p > 0.05), whereas the length–weight relationship was calculated as W = 0.009TL2.97 (R2 = 0.86) for females and W = 0.009TL3.27 (R2 = 0.91) for males. Four size groups (19–22, 23–26, 27–30, >30cm) were established in the study. Significant histological changes, such as macrovesicular steatosis degenerations, were observed in the liver tissue of the examined fish, especially in larger size groups. Females exhibited higher levels of condition and hepatosomatic index values compared with males, possibly because they are more susceptible to liver degeneration. During the summer months, liver degeneration is more striking due to hunger among common soles. Based on these results, 36.7% of the specimens caught from fishing grounds in Izmir Bay have normal liver tissues, whereas 11.3% have macrosteosis and 8.3% have a sinusoidal hemorrhage.
ABSTRACT Engin, S.; Gurkan, S., and Taskavak, E., 2024.土耳其爱琴海成年普通鳎鱼（Solea solea L. 1758）肝脏组织的细胞变化。沿海研究期刊》，40（4），740-748。夏洛特（北卡罗来纳州），ISSN 0749-0208。本研究调查了普通鳎鱼（Solea solea (L. 1758)）肝脏组织中的细胞变化和生物指数，以性别、体型组和季节为基础。研究中使用的标本是 2019 年至 2020 年期间每月从土耳其爱琴海沿岸伊兹密尔湾渔场的商业拖网渔船和小规模捕捞作业中获得的。本研究共使用了 240 尾普通鳎鱼（166 尾雌鱼、66 尾雄鱼、8 尾未成熟鱼）。所获标本的雌雄比例为 0.39:1 (χ2 = 33.19; p > 0.05)，雌鱼的长度-重量关系计算结果为 W = 0.009TL2.97 (R2 = 0.86)，雄鱼的长度-重量关系计算结果为 W = 0.009TL3.27 (R2 = 0.91)。研究中设立了四个体型组（19-22、23-26、27-30、>30 厘米）。在受检鱼类的肝组织中观察到明显的组织学变化，如大泡性脂肪变性，尤其是在较大规格组中。与雄鱼相比，雌鱼表现出更高的体况和肝功能指数值，这可能是因为雌鱼更容易发生肝脏退化。在夏季，由于普通鳎鱼的饥饿，肝脏退化更为显著。根据上述结果，在伊兹密尔湾渔场捕获的标本中，36.7%的肝组织正常，11.3%的肝组织大骨节病，8.3%的肝组织窦状出血。

ABSTRACT Stalter, R. and Lonard, R.I., 2024. Biological flora of coastal salt marshes: Iva frutescens L. Journal of Coastal Research, 40(4), 809–815. Charlotte (North Carolina), ISSN 0749-0208. Iva frutescens L., also known as marsh elder, has a broad distributional range, from the Atlantic coast of Nova Scotia, Canada, to Florida in the United States and from Florida on the Gulf of Mexico to the central Texas coast. Iva frutescens typically occurs in the upper tidal ecotone of salt marshes with more terrestrial upland vegetation. Marsh elder is a hardy shrub that is relatively intolerant to flooding but has a relative tolerance to low soil salinity. Iva frutescens recovers quickly after cutting and fire and may be important in blocking the invasion of Phragmites australis into reconstructed salt marshes. Borrichia frutescens and I. frutescens are associated with the phenomenon of associational resistance. Gall-midge densities in marsh elder stems are reduced when I. frutescens occurs with a second gall-forming host, B. frutescens.
ABSTRACT Stalter, R. and Lonard, R.I., 2024.沿海盐沼的生物区系：海岸研究杂志》，40（4），809-815。Charlotte (North Carolina), ISSN 0749-0208.Iva frutescens L. 又名沼泽接骨木，分布范围很广，从加拿大新斯科舍省大西洋沿岸到美国佛罗里达州，从墨西哥湾的佛罗里达州到德克萨斯州中部海岸。沼泽接骨木（Iva frutescens）通常生长在盐沼与陆地高地植被之间的潮汐上游生态带。沼泽接骨木是一种耐寒灌木，相对不耐洪水，但对低土壤盐度有一定的耐受力。沼泽接骨木在砍伐和火灾后能迅速恢复，在阻止葭萌植物入侵重建的盐沼中可能很重要。Borrichia frutescens 和 Iva frutescens 与联合抵抗现象有关。当 I. frutescens 与第二个形成虫瘿的宿主 B. frutescens 共存时，沼泽接骨木茎中的瘿蚊密度会降低。

ABSTRACT Rahim, A.; Soeprobowati, T.R.; Putranto, T.T.; Hadiyanto, H., and Alfalah, M.H., 2024. Investigating the impact of climate and land use changes on mangrove ecosystems: A bibliometric analysis from 2013 to 2023. Journal of Coastal Research, 40(4), 768–778. Charlotte (North Carolina), ISSN 0749-0208. Mangroves are essential to the stability of coastal regions, especially when facing the threat of climate change. However, deforestation, land use changes, and rising sea levels destroy mangrove forests. Based on bibliometric analysis, this paper aims to gain insight into the impact of climate and land use changes on mangroves. By searching Scopus, 534 pieces of literature from 2013 to 2023 were found, and they were analyzed based on bibliometric information and article metadata. Trends and hotspots of the impact of climate and land use changes on mangrove research were explored using VOSviewer software. The results of a network co-occurrence analysis revealed that mangroves, climate change, land use change, blue carbon, and wetlands represent the most popular central areas of study. The results of this paper show that the countries with the greatest number of publications on mangroves and climate and land use changes are the United States, Australia, India, Indonesia, and China. The research findings revealed that remote sensing and geographic information systems (GIS) are the most recently used technologies to enhance the research field of ecosystem monitoring in mangrove research. Maintaining and increasing carbon sinks through sustainable management of mangrove ecosystems have been a potential priority in climate change and mangrove ecosystem research development. This research highlights trends in the impact of climate and land use changes on mangrove ecosystem research over the past 10 years. It identifies areas that require further research investment to promote future research collaboration.
