The existence of a novel lineage first observed from Puerto Rico (“Lineage 3”) was confirmed in the presence of specimens of C. parallelus from Florida (Lineage 1), and C. mexicanus from Texas (Lineage 2). The novel lineage was found to be in the same phylogenetic clade as specimens from Brazil, consistent with distribution along the Caribbean coast as far as South America. Lineages 1 and 2 are spatially isolated, with no fat snook reported from Pensacola, Florida to Freeport, Texas. The transition zone between lineages 2 and 3 may occur in the area between the Yucatán Peninsula and western Panama. Sampling from this region is necessary to identify the breakpoint and potential for hybridization. Analysis of sequence data within a maximum likelihood framework revealed that all three lineages form a monophyletic clade within Centropomus, with Lineage 3 as ancestral to the other two lineages. Lineage 3 may have originated in South America and expanded to seed the other two lineages. This expansion is estimated to have occurred 0.9-2.5 million years ago. Lineage 3 individuals occasionally migrate to the Atlantic coast of Florida from the distal area of their distribution range and hybridize with local specimens of Lineage 1, suggesting some overlap in the distribution of these two lineages. Overall, these data suggest a complex underlying phylogenetic history of fat snooks in the western Atlantic, with the potential for future taxonomic revision.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884495","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 observed fish fauna, consisting of 127,351 individuals of at least 79 species, was dominated by rockfishes (genus Sebastes; 94.5% of individuals, 47% of species). The Footprint is home to a complex of benthic habitats that are occupied by a number of fish assemblages. These were defined by bottom depth, habitat type, and the environmental tolerances and preferences of each species. While the habitat-limited benthic species that occupy the shallower parts of the Footprint are isolated from the Santa Cruz Island and Anacapa Island shelves, the fishes living on the Footprint are not reproductively isolated. Rather, through a web of connections, the fishes of the Footprint are likely well integrated into the Southern California Bight. This connectivity, flowing towards and away from the Footprint, means that events hundreds or thousands of kilometers away may have profound effects on the fish assemblages on this feature. For example, economically important species were relatively uncommon, possibly the result of past overfishing locally and a lack of immigration from other regions.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884256","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}

However, the composition and spatial distribution of these communities are not well understood. Community transitions have been proposed in the central portion of the WFS around Tampa Bay, Cedar Key, and as far south as Charlotte Harbor, but supporting data are sparse. Fifteen sites in three regions of Florida were surveyed for species distribution, density, and demographics. Distinct communities were found between St Teresa, Hudson, and Tarpon Springs. Coral and sponge densities were highest off Tarpon Springs followed by St Teresa and lowest off Hudson. Stony corals (Siderastrea radians, Cladocora arbuscula, and Phyllangia americana) and octocoral complexes (Muricea spp. and Plexauridae) were the main drivers of differences between the regions. Several species of corals significantly varied in size between the three regions and stony corals in Tarpon Springs were significantly larger in 2021 than in the same region in 2017. Overall, the communities had healthy corals with no disease and minimal bleaching. This research broadens the understanding of WFS hard bottom communities and their spatial distributions through detailed surveys. Additional research on the hard bottom communities of the WFS is necessary to attain a comprehensive understanding of the coastal shelf and support long-term management.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"65 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884465","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}

There are two major volcano features in the SBC: Il Duomo (about 20 m high, cresting at a bottom depth of 115 m) and Il Duomito (about 15 m high, cresting at 185 m). While the geology of these features has been well studied, their fish assemblages have not been well documented. Using an autonomous underwater vehicle, we surveyed the fishes that live on the volcanoes and on the surrounding mud. We observed 1836 fishes, which represented a minimum of 43 species. Of these species, at least 23 (53.5%) were of rockfishes (genus Sebastes). Most of the species were entirely or primarily associated with a specific habitat type, either asphalt or mud. The most abundant primarily asphalt-associated species were greenblotched, swordspine, greenspotted, and flag rockfishes, and bocaccio, cowcod, and bank rockfish. The most abundant mud-associated species included Pacific sanddab, slender, Dover, and English soles, and unidentified poachers. A few taxa (shortspine combfish, greenstriped rockfish, and spotted ratfish) were found both on the mud and over the edges of the asphalt. We observed relatively low densities of all fishes on the volcanoes compared to densities on many southern California natural reefs within the same depth range. We suggest that this is due to (1) a lack of cobble fields around the volcanoes, creating limited habitat for either dwarf species or juvenile fishes, (2) a lack of complex habitat (volcanoes are relatively smooth) creating very limited habitat for adults that need to shelter, and (3) fishing pressure targeting economically important species. Given the unique nature of these tar volcanoes off California, we also suggest the state consider protecting this habitat and the organisms within it.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884714","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}

An increased frequency of snappers, groupers, and amberjack were observed at Sonnier Bank, predominately in mesophotic depths, indicating the Sonnier MCE as either a hotspot or potential refuge for meso-and apex predators.

We aimed to (1) provide the first baseline of mollusk diversity in sediments of the NW region, and (2) test if there were west-east gradients of α- and β-diversities. We found 141 species in sediments: 68 deepsea benthic, 43 shelf benthic, and 30 pelagic species. The richness of pelagic species was similar along the NW region indicating significant settlement of pteropod shells to the seabed. The occurrence of shelf species in the deepsea suggested a downslope transport of shells enhanced by the slope steepness and dredging in two ports. β-diversity of deepsea benthic mollusks showed a high turnover at local scales explained by habitat heterogeneity. β-diversity of pelagic species was extremely low suggesting that the planktonic assemblage was evenly distributed. In contrast, high β-diversity of shelf benthic species occurred likely due to downslope transportation of materials. Deepsea gastropods were mostly detritivores, while bivalves were mostly suspension feeders. These dominant biological traits indicated oligotrophic conditions in sediments likely coupled with an intense hydrodynamic regime in the deepsea. The NW Cuban region seems to be a hotspot for mollusk diversity because of the discovery in a single expedition of seven new species, 12 new records, and 36% endemism relative to the entire Gulf of Mexico. Our findings revealed a complex and diverse mix of deep/pelagic/shelf species but did not indicate a west-east gradient in the mollusk assemblage structure.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70884478","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}

While host-mediated dispersal is an important driver of gene flow in many terrestrial metazoan symbionts, few studies have identified the drivers of symbiont genetic differentiation in the marine realm, where habitats are comparatively more homogeneous and long-distance dispersal is common. In the present study, we perform a meta-analysis of existing studies examining symbiont spatial genetic diversity to determine which symbiont- and host-related traits shape the patterns of genetic differentiation of metazoan symbionts, while also considering technical aspects of each study. Specifically, we wanted to assess the influence of biological traits and/or technical aspects in (1) detecting genetic differentiation in marine symbionts, and (2) shaping the minimum spatial scale at which genetic differentiation was detected. By assessing genetic diversity of mtDNA markers, we found that the spatial scale at which studies are conducted was a crucial predictor of both detection of genetic structure and scale at which differentiation of marine symbionts was detected. Symbiont-based traits did not influence genetic structure, however, host-mediated dispersal was the only biological trait that shaped genetic structure of marine symbionts by influencing the spatial distribution at which differentiation was detected.","PeriodicalId":55312,"journal":{"name":"Bulletin of Marine Science","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70883636","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}
