The burial of leaves inside the sediment suggests a positive relationship between crab activity and carbon storage in mangrove forests. However, crab burrows increase the sediment-air interface and, thus, might amplify CO 2 fluxes from the sediment. Additionally, the tidal export of carbon from burrows acting as preferential flow paths may offset the enhancing effect of crab burrows on carbon storage. In this study, we investigated the interactive effect of burrowing crabs and tidal flows on mangrove carbon storage in a laboratory experiment. Significantly higher dissolved organic carbon (DOC) concentrations in the porewater were found in microtidal compared to mesotidal treatments, while the total amount of outflowing DOC was similar across tidal treatments. No significant effect of burrowing crabs on the DOC content of the porewater was found. Significantly lower CO 2 fluxes into the atmosphere were found in treatments with crabs present which is contrary to previous studies. We suggest that lower CO 2 flux values were a result of collapsed burrows that preserved the particulate organic carbon (POC) in deeper sediment layers. Previous studies, showing enhanced CO 2 fluxes from crab burrows, have been carried out in the field and did not take the potential of burrow collapse into account. We stress the importance of considering temporal variability in crab burrow stability and spatial variability in tidal dynamics when evaluating their interactive effect on carbon fluxes in mangrove forests.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"101 3","pages":"1221-1236"},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147907786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we analyze 12 demersal longline sampling expeditions circumnavigating continental shelves in the Gulf of Mexico (GoM) during 2011-2017. Two Ophichthid eels were dominant components of fish assemblages: king snake eel (KSE), Ophichthus rex, and palespotted eel (PSE), Ophichthus puncticeps. Relative abundance (CPUE) of KSE was highest in the north central GoM, lower in the northwest and southeast and on the West Florida Shelf, and absent from northwest Cuba and the Yucatán Platform. Contrariwise, PSE abundance was highest on the Yucatán Platform, lower in the north central GoM and on the West Florida Shelf, and absent from the northwest and southwest GoM and Cuba. GAM-based species distribution models were fit to presence-absence data from sampled stations using a variety of environmental covariates including water depth, longitude, and sediment type (sand vs mud/silt). Although the two species were caught in similar depths and bottom temperatures, they were only caught together at 1% of the stations. This study extends the record length of KSE to 226 cm (total length). Despite being abundant in areas overlapping the footprint of the Deepwater Horizon oil spill in 2010, concentrations of polycyclic aromatic hydrocarbons (PAHs) and their metabolites were relatively low in KSE, perhaps related to copious slime production which, in other studies, has been determined to be a vector for PAH excretion in fishes.ResumenLas especies de anguilas ofictidas son abundantes y diversas en los mares tropicales y semitropicales; sin embargo existen pocos estudios sobre las historias de vida de las anguilas serpiente y los factores que influyen en sus distribuciones espaciales. En este estudio analizamos 12 expediciones de muestreo con palangre demersal desarrolladas en la plataforma continental de todo el Golfo de México (GoM) durante 2011-2017. Dos anguilas Ophichthid fueron componentes dominantes en los conjuntos de peces: lairón (KSE), Ophichthus rex, y tieso de puntos pálidos (PSE), Ophichthus puncticeps. La abundancia relativa (CPUE) de KSE fue más alta en el centro norte del GoM, menor en el noroeste y suroeste y en la plataforma del oeste de Florida, y nula en el noroeste de Cuba y la plataforma de Yucatán. Por el contrario, la abundancia de PSE fue mayor en la plataforma de Yucatán, menor en el centro norte del GoM y en la plataforma occidental de Florida, y nula en el noroeste y suroeste del GoM y en Cuba.

However, populations of this species are experiencing declines due to overcollection, use as bait, and other anthropogenic factors. Citizen science holds great potential as a useful complementary tool to traditional monitoring efforts, so we evaluated horseshoe crab observations uploaded to the citizen science platform iNaturalist. Across 10,094 observations, the majority of which occurred primarily during summer months, the number of observations increased annually from 2008 to 2022, presumably as this platform is gaining popularity in overall use by citizen scientists. Analyzing a subset of images from this dataset, we found evidence of scavenging, ranges in the number of individuals, and additional organisms (mollusks or barnacles) attached to specimens, with 52.7% live versus 38.9% dead, and most images showing a complete specimen (61.6%) and adult life stages (80.3%). Most observations were taken on sand (75.7%), with some in shallow water (9.4%) or in vegetation (7%). We recommend researchers incorporate this freely available database as a complementary conservation tool to document presence and natural history and to monitor population trends both in this species and other marine species.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135755388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water quality of coastal waters of Liaodong Bay was evaluated using the comprehensive water quality evaluation index, Nemerow index, and principal component analysis. Dalian and Huludao were found to have significantly better water quality than Panjin, Yingkou, and Jinzhou near the Liaohe Estuary. Marine functional areas and seawater quality index were spatially correlated, and the intensity of sea area development and utilization had a significant positive correlation with the comprehensive evaluation index of seawater quality and Nemerow index. The per capita gross domestic product of coastal cities and seawater quality index followed an “inverted U-shaped” Kuznets curve. Variance decomposition analysis showed that the intensity of sea area development and utilization cumulatively explained 42.3% of the changes in the quality of the seawater environment, while the economic and industrial structure cumulatively explained 31.8%. The direct impact of the intensity of development and utilization of the sea area and the economic and industrial structure contributed 16.5%, while interaction between the natural geographical location and sea area development and utilization intensity and economic and industrial structure cumulatively explained 58.9% of the changes. Our results strongly support management and control of sea reclamation, comprehensive management of coastal waters, and optimization of coastal industrial structure to improve the environmental quality of coastal waters.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a soft and flexible body, only a few attempts have been made to quantify the growth rate, either in the field or in aquarium systems. In this study, the planar area measurement approach was applied and evaluated for its applicability to soft corals. All fragments of Sinularia penghuensis and Cladiella hartogi were placed on individual tiles (10 × 10 cm) and randomly distributed in the mesocosm. Two treatments were applied: (1) finger touch treatment, and (2) air exposure for one minute to avoid the influence of morphological flexibility caused by the hydroskeleton before taking photographs underwater. Two independent tests were carried out including (1) applying two treatments before taking photographs for four sides (only for S. penghuensis), and (2) comparing the planar area and linear measurement with its dry weight (for both species). Since the shape of C. hartogi is stable through time, the first test was not required for C. hartogi. The photographs were taken twice per day (11:00am and 8:00pm), and five pictures were taken for each side. The results showed that there was no significant difference between one and five pictures used (P > 0.05). Furthermore, taking photographs of two sides that are perpendicular to each other is recommended to provide sufficient statistical power. Meanwhile, the air treatment made the fragments less flexible during the photographing process which should be used in this standardized 2D image analysis. Our results also showed that planar area was strongly correlated (P < 0.001) with its dry weight (R2 = 0.929 for S. penghuensis and R2 = 0.945 for C. hartogi). In addition, the air exposure treatment was consistently similar during both times (daytime and nighttime). Based on the results, we suggest this standardized 2D method to measure the growth of soft corals by measuring planar area changes through time.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70885410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
