The present study deals with the first status on the Suape port ecosystem, recorded from 41 sediment samples throughout the Massangana/Tatuoca and Ipojuca/Merepe estuarine systems. Species diversity values are higher in the seaward part of the bays and decreases toward the inner parts. The dominance of Ammonia tepida in the inner portions of the bays is indicative of environmental instability and pollution of coastal waters. Eggerella spp., unusual in Brazilian fauna, was present only in the innermost portion of the Tatuoca estuary, in the dredged channel, where heavy metal impacts have been reported. Amphistegina gibbosa, Triloculina oblonga, and Quinqueloculina lamarckiana are represented on the outside of the bays and are indicative of high hydrodynamic marine environments. The Ipojuca and Merepe rivers presented the highest ecological index, possibly attributed to the marine and terrestrial/mangrove influence for the region. We infer that geomorphological transformation caused by the Suape Port installation modified and established environments with distinct characteristics, mainly in the Suape Bay dredged area, indicative of possible eutrophication of this environment. The new data may be useful for determining environmental conditions and establishing new ways to monitor the consequences of anthropogenic interference and dredging in the Massangana/Tatuoca and Ipojuca/Merepe estuarine systems.","PeriodicalId":54832,"journal":{"name":"Journal of Foraminiferal Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42548698","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 spring waters have high alkalinity and high calcium concentrations due to the Paleogene limestone lithology of this region. Benthic foraminifers are abundant on the shallow shelf, including Archaias angulatus which hosts chlorophyte symbionts. This study was motivated by the hypothesis that areas of discharge from limestone lithofacies may provide refugia for calcifying organisms during ocean acidification. Environmental data and sediment samples were available from 41 sites at depths <8 m. Benthic foraminiferal species identified (142) included 65 porcelaneous, 65 hyaline, and 12 agglutinated taxa, with 13 species sufficiently common to make up ≥2% total relative abundance. Overall, 58% of the specimens were porcelaneous and most of the remainder were hyaline. Smaller miliolids dominated in samples from most of the inshore polyhaline sites (22–30), while hyaline taxa co-dominated the more offshore sites (salinities >30), representing a distribution reversal compared to previous reports from Gulf of Mexico coastal habitats. The elevated alkalinity and calcium ion concentrations associated with freshwater discharge from limestone lithofacies allows Ar. angulatus and small miliolids to thrive in polyhaline waters.","PeriodicalId":54832,"journal":{"name":"Journal of Foraminiferal Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46306238","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}

These specimens with a flat, discoidal test, occasionally with an indistinct central depression, possess a central layer of equatorial chambers/chamberlets displaying a cyclical (orbitoidal) growth pattern and thick lateral layers with numerous chamberlets. The megalospheric embryonic apparatus possesses three small chambers (a triconch, the chambers of which are separated by notably thin walls), followed by a large auxiliary chamberlet. These specimens closely correspond to the genus Caudriella Haman and Huddleston and its type-species Margaritella ospinae (Caudri) that has only previously been reported with confidence from the Caribbean region, notably the type locality within the middle Eocene Punta Mosquito Formation at Margarita Island off Venezuela. Caudriella at its type locality also possesses a trilocular embryonic apparatus, which was incorrectly interpreted as arranged in a rectilinear or slightly curved row. The diagnosis of Caudriella is emended and considering the similarities in their equatorial sections with closely associated Linderina Schlumberger, a comparison of their embryonic-nepionic stages is given from the same deposits in NW Turkey and with those from the middle Eocene of the Sulaiman Range (Pakistan) and Kutch (India). A new record of primitive Caudriella is presented from Jamaica. The palaeobiogeographic distribution of Caudriella is reconsidered, being recorded from both the American/Caribbean and the Western Neo-Tethys bioprovinces. Limited data suggest eastward directed dispersal of the genus, even though this would be counter to most of the prevailing surface currents during the Eocene.","PeriodicalId":54832,"journal":{"name":"Journal of Foraminiferal Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46789081","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}

We generated high-resolution age models using larger benthic foraminifera biostratigraphy and recorded the change in microfacies. The LBF microfacies in SBZ 3 (∼58–60.7 Ma) and SBZ 4 (56–58Ma) is dominated by Miscellanea, Glomalveolina, Ranikothalia, orthophragminids, dasycladalean green algae and coralline red algae, indicating that deposition occurred within inner to mid-ramp environments. An abrupt shift in the depositional setting from open marine Lakadong Limestone to restricted marine Lakadong Sandstone across the PETM possibly indicates major changes in hydrological cycle during the extreme warmth that followed the PETM. The marine sedimentation continued during the Early Eocene (SBZ 7–9 corresponding to 55.1–52.8 Ma) within Meghalaya that led to the formation of Umlatdoh Limestone dominated by Halimeda, Alveolina, and miliolids. The larger foraminiferal extinction and origination in the Meghalaya basin is marked by the extinction of late Palaeocene Ranikothalids, Glomalveolinids, dominating the Lakadong Limestone and the dominance of Alveolinids and Discocylinids in the early Eocene Umlatdoh Limestone.","PeriodicalId":54832,"journal":{"name":"Journal of Foraminiferal Research","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47438807","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}
