Dissolved oxygen (DO) and other redox elements, pH, P distributions, as well as chlorophyll <em>a</em> (Chl-a) and alkaline phosphatase activity (APA) were measured. On-site experimental results revealed that OP photolysis significantly contributed to inorganic phosphorus (IP) generation. The enhanced OP hydrolysis caused by algal enzyme secretion under IP scarcity stimulation is also important for IP release. Algal growth governed by differential P utilization among various P species, induced different patterns of pH and DO variations. The simulation experiment containing sediment showed that throughout the entire cultivation process, the DO penetration depth of all algal groups showed an upward trend with a higher value in the IP group. This result further affected the bioavailability of P in the sediment. The distribution of P fractions in the sediment after cultivation indicated that extractable phosphorus (Ex-P) of the groups containing algae was lower, while iron-bound phosphorus (Fe-P) and OP were obviously higher than those in the groups without algae.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"329 ","pages":"Article 109643"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685001","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}

Tests focused on how the performance of the SW under various regular wave heights and periods was affected by either the presence of an offshore structure in front of the wall or the placement of uniformly energy-dissipating blocks (EDB) of triangular or trapezoidal geometries on the SW surface. The results indicate that Kr decreases as wave steepness (H_i/gT²), relative depth (d/L_i), and relative submerged width (B/L) increases, and as seawall slope (cot θ) decreases. These parameters were more effective in controlling wave hydrodynamic characteristics than the surf similarity parameter (ξ). Notably, the performance of a 45° sloping plane SW was substantially enhanced by adding horizontal reversed-triangle blocks with a narrow spacing (S/W = 1), resulting in a reduction in Kr of approximately 37 %–49 %. The addition of a submerged breakwater (SB) in front of a vertical SW decreased Kr and relative run-up (R_u/H_i) by about 29 %–46 % and 5 %–34 %, respectively, compared to the plane SW alone.

We calculated moisture content (MC), condition (CI), gonadosomatic (GSI) and muscle (MI) indices, and meat yield (MY), seasonally. The soft tissue MC averaged around 82 % and varied seasonally, with differences noted between various soft tissue parts. The GSI results indicate that <em>P. jacobaeus</em> experiences three potential spawning peaks annually: a major one in late winter/early spring, and weaker ones in early fall, and a posibble in early winter. The sea temperature emerged as the most significant environmental factor influencing the reproductive cycle of <em>P. jacobaeus</em>, showing a negative correlation with GSI. In contrast, river inflow positively correlated with GSI, suggesting that food availability plays a crucial role in supporting gonadal development. Additionally, an extreme decline in salinity can have detrimental effects on reproduction. A significant negative correlation between GSI and MI, implies that energy allocation is divided between muscle and gonads, indicating that muscle reserves are utilized for gonad development. According to the results of the GSI analyses, we can suggest that spring is the optimal season for collecting wild spat or broodstock for aquaculture development, while summer is the best time for harvesting natural populations when the muscle reaches its maximum size.</div></div>","PeriodicalId":50497,"journal":{"name":"Estuarine Coastal and Shelf Science","volume":"329 ","pages":"Article 109669"},"PeriodicalIF":2.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790352","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}

The study quantified key foraminiferan traits, tested trait–environment relationships, and compared functional diversity (FRic, FDis, RaoQ), redundancy, and vulnerability across the inner, middle, and outer zones of Krossfjord using RLQ and fourth-corner analyses. Trait analysis of 43 species showed that communities were dominated by infaunal strategies, calcareous tests, muddy-sand substrates, suboxic affinities, and fresh food preferences, with only weak shifts among zones. Functional diversity was broadly similar across the fjord gradient, with a tendency for slightly higher functional richness in the outer fjord and slightly higher functional dispersion and Rao's quadratic entropy in the inner fjord. Test material was the only trait significantly associated with environmental gradients, with agglutinated forms more common in the inner fjord and calcareous forms prevailing in the outer fjord. The study identified 35 functional entities, of which 37 % were represented by a single species, indicating potential functional vulnerability.

Galicia (northwestern Spain) is the leading producer of farmed mussels in Europe, and most of mussel rafts are seeded with wild spat collected from intertidal rocks. Using a UAV equipped with an RGB camera and LiDAR sensor, we surveyed a rocky intertidal area in Galicia where mussel spat are harvested.
