Local variations in species abundances also contributed to differences in composition observed at the assemblage scale.

The significance of freshwater taxa to the overall communities was higher in stations where higher river inputs were expected. Feces- and sewage-associated bacteria were found at multiple locations, highlighting the occurrence of anthropogenic contaminants.

Multivariate statistical analysis indicated that various factors, such as sediment grain size, nutrient, Al, Fe contents and concentration of inorganic pollutants (As, Hg, Ni, Pb, Zn) significantly contribute to the assembly mechanisms of prokaryotic communities in these lagoons. Our results imply that riverine freshwater inputs and human activities jointly shape the microbial composition of these lagoons, which is consistent with their close connection to the Adriatic Sea.

Additionally, this paper presents a general LSTR derived from the derived peak LSTR equation. The general equation for the LSTR is then validated by comparing it with five conventional equations, notably the famous CERC (1984)and Kamphuis (1991), using observed values of waves, sediment, and the LSTR collected from 12 beach sites in the United States.

Two complementary objectives are pursued: (1) to investigate depth-related patterns in the diel cycle of fish sounds using generalized additive models, and (2) to assess whether their realized acoustic niches change between depths. Although most sound types were shared between 60 and 120 m, the study revealed that the dynamics of fish sounds varied significantly between the two depths. It also supported clear diel patterns. As depth increased, frequency-modulated sounds became more prominent at night, while the opposite trend was observed for pulse series sounds. At the community level, acoustic activity was more concentrated during short time periods at night at 120 m. Different sound types were either produced at distinct times or differed in pulse period range or frequency spectrum during periods of temporal overlap. The structure of realized acoustic niches also differed between the two depths. The consistent increase in the abundance of frequency-modulated sounds under reduced light conditions (both at night and in deeper waters) may reflect the need for more stereotyped acoustic signals, suggesting a potential adaptation to low-light environments.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"322 ","pages":"Article 109336"},"PeriodicalIF":2.6,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144116335","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}

This study aimed to determine whether the recovery of the ghost crab metapopulation observed during the pandemic persisted into the post-pandemic period and following the creation of a locally managed Environmental Protected Area (EPA). Monthly data on burrow abundance and opening diameter from the lockdown (2020–2021) and post-pandemic (2022–2023) periods were analyzed and compared with historical data from pre-pandemic times (2013–2019) across areas with varying levels of urbanization and human disturbances. We hypothesized that burrow abundance and burrow opening diameter in urbanized areas decrease in the post-pandemic period compared to the lockdown even after the establishment of the EPA. A significant increase in burrow density in the most urbanized areas was observed during the lockdown and post-pandemic periods compared to pre-pandemic times, likely attributed to the \"anthropause\" and the restriction of activities such as vehicle traffic within the EPA. However, the most urbanized areas recorded the smallest burrows even during the lockdown and post-pandemic periods compared to non-urbanized areas, suggesting that recreational activities still affect individual energy budget and growth.

We used an individual-based model (IBM) to assess the larval connectivity patterns of the wedge clam during the period 2000–2012. The IBM combines a 3D hydrodynamic model with a biological sub-model that considers larval mortality due to low salinity (&lt;7, and &lt;9) and sea surface temperature range (high &gt;30 °C or low &lt;9 °C). The main larval connectivity patterns were observed near the release/recruitment areas, suggesting a high potential for self-recruitment. Based on the IBM and adult abundance data, we also identified the likely source and sink areas within this metapopulation. Source beach areas were Navegantes and Cassino in Brazil (from 26.3° S to 34.34°S), Arachania in Uruguay (34.56°S), and Santa Teresita in Argentina (37.15°S). A low probability of larval transport towards the poleward limit of the species' distribution was observed, supporting an irregular recruitment pattern typical of sink populations located at the edge of the distribution range of metapopulations. Larval mortality due to warm or cold waters did not affect connectivity patterns for this subtropical species. Southward larval transport across the RdlP estuary (from Uruguayan to Argentine beaches) only occurred for larvae released on early January 2011, concurrently with the strongest La Niña year observed during the study period.
