We tested hypotheses about spatial and temporal patterns in settlement and subsequent recruitment during two successive years using three sets of field experiments based on deployment of seed collectors. Both species showed significant, but unpredictable variability in settlement among sites with prevalence of complex small scale spatial and temporally interactive patterns. Recruitments patterns were in many respects similar to those of the settlement. While <em>M. gigas</em> showed a significantly higher settlement at sites with adult <em>O. edulis</em>, the pattern for <em>O. edulis</em> settlement was not equally linked to the presence of adult oysters. Both settlement and recruitment of <em>O. edulis</em> increased with depth while the opposite was true for <em>M. gigas</em>. Many of the ecological patterns observed were general and predictable, such as the primary settlement period. While the effect of position in the water columns was markedly different between the two species with <em>M. gigas</em> settling closer to water surface. The observed pattern suggests that settlement of <em>O. edulis</em> to some degree are limited by the availability of suitable substrate. Understanding these fundamental spatial and temporal recruitment patterns of the oysters are important for effective management of bivalve and successful implementation of restoration initiatives.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"313 ","pages":"Article 109094"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the interactive processes that influence and control the species composition, diversity, relative abundance, and size structure of inner surf zone fish assemblages in a highly diverse tropical region. Beach seine sampling was conducted at three distinct sampling sites for 12 consecutive months during the new and first quarter moon phases, with replicates collected during both day and night periods, on Serrambi Beach, Pernambuco State, northeast Brazil. Generalized Linear Models (GLM) were applied to assess the relationships between species richness and abundance and explanatory environmental variables. A set of environmental variables was measured at each sampling point. A total of 19,026 individuals belonging to 84 taxa were caught, with fourteen taxa comprising 87.5% of the total number of individuals, representing an equitable and constant composition throughout the year. GLM results showed that the sampling point alone explained 16% and 38% of the richness and abundance models, respectively. Temperature had a stronger influence on the structure of the fish assemblage than salinity. Fish size distribution ranged from 8 to 450 mm SL, and individuals between 10- and 120-mm SL represented up to 97% and occurred systematically throughout the year. Our results suggest that proximity to reefs results in a fish assemblage that is more abundant, diverse, and temporally stable. The presence of small individuals of the dominant species is likely an ontogenetic strategy, where juveniles use the shallow areas of the surf zone as a “standby transient habitat,” finding protection from predators and food while seeking suitable conditions to later move to nearby coastal environments and complete their life cycle or even remain within the surf zone itself.

Here, we investigated the impact of rainfall on tidal channel evolution, based on field investigation of geomorphic change and a numerical model (MIKE21 FM). The results indicate that intense low-tide rainfall promotes formation of tidal channels. Rainfall induces rill erosion, facilitating rapid formation of a rill network. Initial tidal currents converging through the rill network enhance sediment transport, leading to rapid development of a tidal channel network. The tidal channel network inherits features from the rainfall-induced rill network, retaining up to 34% of these characteristics after 30 tidal cycles. Furthermore, long durations, steep slope, micro-tidal conditions, and peaked rainfall pattern enhance the effect of rainfall on tidal channel network morphodynamics. There exists a critical slope threshold for a specific high-intensity rainfall. Rainfall dominates channel length when slope is above this threshold, whereas tides become dominant as slope is below it. These findings provide an explanation for the rapid growth of tidal channels during rainy seasons in earlier field observations, indicating that rainfall condition should be incorporated into research of coastal wetland evolution.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"313 ","pages":"Article 109108"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In decapod crustaceans, the external body shape has been identified as an essential trait to assess the invasive potential of species given its relevance in their biological and ecological performance. The present study analyses the abundance trends of two tropical anomuran decapods that expanded their distribution and established in the western Mediterranean in recent decades (the squat lobster <em>Iridonida speciosa</em> and the hermit crab <em>Pagurus mbizi</em>) and assess their impacts on the population dynamics of their taxocoenoses along the Iberian Peninsula (western Mediterranean Sea) over 25 years (1994–2018). In addition, external morphology, measured with geometric morphometric methods, was used to characterize the taxocoenoses to evaluate whether it contributes to understanding the invasive ability of allochthonous species. The results showed that the exotic species that achieved dominant levels (<em>I. speciosa</em>) presented some particular morphological differences from native species that likely provide it with greater exploitation efficiency or unoccupied niche opportunities to avoid or overcome competition with residents. However, the invader that settled itself apparently favoured by external or environmental variables but failed to establish dense populations (<em>P. mbizi</em>) was morphologically similar to native species. This overlap probably implies ecological competition for the available resources, thus reducing the probability of becoming abundant within the taxocoenosis. The findings of the model agree with those obtained in other taxonomic groups, which reinforces the hypothesis that external morphology is an additional element to be considered within the complex combination of factors determining the success of marine invasive processes.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"313 ","pages":"Article 109114"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario, the loss of habitat-forming species is of great concern since they facilitate the occurrence of other organisms. These habitat-forming organisms facilitate the occurrence of other species by providing new habitats or increasing the complexity of existing ones. Also, they can minimize adverse abiotic conditions and negative interactions and, thus, their presence allows for the development of an abundant and diverse associated fauna, such as amphipod species. Amphipods have an intimate relationship with macroalgae and can use macroalgae as shelter and food. Marine macroalgae have been under strong decline in abundance and diversity, mainly due to climate change. The loss of diversity of host macroalgae means the loss of the facilitation process that these organisms perform, potentially affecting associated amphipods. Thus, the aim of this study was to investigate how the loss of habitat-forming species affects the associated fauna. Specifically, the questions are (1) What is the effect of host macroalgal diversity on the amphipod assemblage? (2) What is the relative importance of richness and identity of host macroalgae for the amphipod assemblage? To answer these questions, a field experiment is conducted to manipulate the richness of host macroalgae <em>(Dichotomaria marginata, Padina gymnospora, Sargassum filipendula)</em> on a subtropical rocky shore (Ubatuba, SP, Brazil). Treatments ranged from monoculture to polycultures, combining additive and substitutive designs. The polyculture treatment harbored higher amphipod abundance and richness than monocultures and had a unique assemblage composition. These results were attributed to the richness, but not to the identity of host macroalgae. This pattern was observed in additive and substitutive experimental designs performed. Moreover, an overyielding of the polyculture relative to that expected from the individual contribution of the monocultures (Dt &gt; 0) and based on the yield of the best monoculture (Dmax&gt;0) is observed, indicating a complementarity effect. These results show that more diverse substrates provide a greater variety of resources (e.g. habitat and food) than monospecific substrates, harboring a richer associated fauna. Therefore, the importance of maintaining the diversity of host macroalgae for the associated faunal community should be emphasized.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"313 ","pages":"Article 109091"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in certain areas of tidal flats, the natural tidal inundation is partially obstructed by artificial structures, resulting in incomplete correspondence between the inundation frequency and the topography. Therefore, this study proposes the frequency-distance joint retrieval (FDJR) approach to improve the tidal inundation frequency method. The FDJR approach derives the local multi-year lowest tidal level line, characterized by an inundation frequency of 1, from the inundation frequency image. It further incorporates the landward distance between this line and the tidal flat point into the regression model, thereby effectively capturing the overall monotonic variation in the elevation of the tidal flat profile. Taking the Yellow River Delta (YRD) as an example, the retrieval of tidal flat topography was conducted by integrating Sentinel-2 remote sensing images, ICESat-2, ATL08 elevation products and RTK measured terrain. The results show that there exists a high correlation among the landward distance, inundation frequency and elevation. Moreover, the machine learning regression model based on Random Forest and Bagging algorithm effectively characterizes this relationship. Compared with the tidal inundation frequency method, the proposed approach achieves an increase in training accuracy of approximately 30 %-40 % while providing more concentrated retrieval elevation distribution with smoother kernel density curves. The FDJR approach proves applicable to the tidal flats where natural tide inundation is partially obstructed and provides topographic reference for coastal zone studies.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"313 ","pages":"Article 109061"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
