Floral oils are used in provisioning, building, and lining the brood cell and nests. The genus Epicharis has a neotropical distribution and females are closely associated with plants of the Malpighiaceae family, with the highest number of records in species of the genus Byrsonima. However, due to the strong seasonality of adult activity and solitary behavior, knowledge about important floral resources to Epicharis bees is still scarce. In order to identify important resource sources for a widely distributed species, the current work aimed to analyze the pollen spectrum of Epicharis flava Friese in an urban area in the Atlantic Forest domain. For this, females of E. flava were captured during five days while visiting flowers of Byrsonima sericea DC. (Malpighiaceae) in an urban area, and the pollen load in their scopae was submitted to acetolysis processing for further analysis under the microscope. In total, 71 pollen types were found, with emphasis on Fabaceae, Solanaceae, Bignoniaceae, and Malpighiaceae, considered sources of nectar, pollen, and floral oils. This study made it possible, through the analysis of pollen in the scopae, to identify a list of potentially important species for the maintenance of E. flava populations. This information is necessary for the management of urban green areas, aiming at increasing biodiversity. In addition, these data can serve as a base for further research on oil-collecting bees in the Neotropics.Keywords: floral oilpollinator-plant interactionsolitary beeurban environmentDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

This region has emerged as a strategic location for researching planktic microfossils, particularly dinoflagellate cysts, in modern and Late Quaternary sediments, offering crucial insights into the biophysical properties of mid-latitude waters. This study examined cyst distribution in marine sediment cores near Maria Island, Tasmania, southeastern Australia, up to 9,000 years before present (kyrs BP). Dominant cysts included Protoceratium reticulatum, Protoperidinium spp. (P. avellana, P. conicum, P. oblongum, P. subinerme, P. shanghaiense), and Spiniferites spp. (S. bulloideus, S. hyperacanthus, S. membranaceus, S. mirabilis, S. pachydermus, and S. ramosus). Inshore, Spiniferites spp. constituted a higher proportion (up to 61%), while offshore was dominated by P. reticulatum (up to 80%). Impagidinium spp. and Nematosphaeropsis labyrinthus were exclusively found offshore from ∼6 kyrs BP, suggesting a shift from shallow to deep-water habitat. Alexandrium tamarense species complex cysts were present over 140 years inshore and approaching 9 kyrs BP offshore, indicating a longstanding endemic presence. Gymnodinium catenatum cysts were detected exclusively inshore from ∼50 years ago, indicating a relatively recent bloom phenomenon.The East Australian Current's limited southward reach is suggested by the absence of warm-water cyst-producing taxa Lingulodinium polyedra. Similarly, the non-detection of cold-water species Spiniferites antarctica and Impagidinium pallidum reflects Subtropical Front boundaries against subantarctic incursions from the south. In contrast to coccolithophores in the same core, no noticeable shift from cold to warm-water dinoflagellate cyst species was observed. This documentation of dinoflagellate cysts aids in predicting environmental impacts on local communities and beyond.Keywords: PalaeoclimateOcean currentsSea level riseDinoflagellate cystsTrophic dynamicsTasmaniaAustraliaDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

The data generated covers a long-time span from the Precambrian to the Holocene of Egypt. Previously published results are devoted primarily to the study of many exploration wells and outcrop sections. Comprehensive studies were carried out on a range of palynomorph groups including spores and pollen, algae and prasinophytes, dinoflagellates, acritarchs, scolecodonts, chitinozoans, and other miscellaneous forms as well as palynofacies. Particular attention is given to the history of palaeopalynology. This study presents three main phases. The results of the first phase were limited, as the knowledge of palynology in Egypt was poorly known from 1959 until 1979. Between 1980-2000, which represents the second or shaping phase, an intensive study of surface and subsurface material was carried out. The third phase (2000 until now) provides the academic and commercial expansion of palynological research in Egypt, where palynology can have immediate application in petroleum exploration studies.In the first phase, the application of palynology is seriously hampered by the limited extent of the published data. Only 27 works emerged by the end of 1979. A considerable acceleration could be noticed in the second phase when palynological research was established in many national institutions and started to play a considerable role in petroleum exploration. Beyond academia, some of the operating oil companies started to set up palynological labs and staff as part of biostratigraphy teams. These included, for example, GPC, Khalda Petroleum Co. with a focus on the north Western Desert, and GUPCO with a focus on the Gulf of Suez, and most of the results obtained were incorporated with the internal data on the well files. During the period 2000-2009, especially when palynofacies studies were incorporated, the progress and the attitude of palynological research changed. This allowed for a more accurate reconstruction of the depositional process and eventually a paleobiogeographic history mainly for the Cretaceous age, which is an important target for hydrocarbon exploration in Egypt. From 2010 onwards, the number of publications has clearly grown and reached 23 publications in 2020. Such a high pace of development seems to have been at the expense of basic research comprising taxonomy and biostratigraphy, something that might negatively impact the quality of research and also researchers, especially the young ones. The change brought about through this phase by integrating organic geochemistry, sedimentology, and other disciplines may, however, have left a positive impact, principally in terms of international collaborations and expansion of palynology applications beyond the standard academic cluster.Important highlights and outputs, and prospective forthcoming developments and recommendations pertaining to Egyptian palynology generally (and in each phase) are di","PeriodicalId":54644,"journal":{"name":"Palynology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135268335","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}

Documented chitinozoan occurrences are mainly from the Miaopo Formation on the Upper Yangtze Platform. The present study reports new data from the Miaopo Formation at the Zhenjin section in the Yichang area. In total, 13 genera and 33 species are recognised, and three new species are described: Spinachitina? coronifera sp. nov., Lagenochitina yichangella sp. nov. and Pellichitina confragosa sp. nov. The Baltoscandian index species, Laufeldochitina striata, is documented in the lowermost part of the formation. This is the first report of this species in South China. The L. striata Biozone is suggested for the basal part of the formation due to the presence of the eponymous species. The index species of the Laufeldochitina stentor Biozone, the Armoricochitina granulifera and Cyathochitina megacalix subzones adopted in the Jieling section are also observed in the Zhenjin section. However, according to the new data obtained at Zhenjin, the first appearance datum of C. megacalix and A. granulifera coincides with that of L. striata. Therefore, the C. megacalix Subzone is kept but moved to the L. striata Biozone. A. granulifera has stable occurrences in almost the entire Miaopo Formation, corresponding to the Nemagraptus gracilis graptolite biozone. It is slightly older than Baltic records but could be useful for recognising this time interval in South China.Keywords: biostratigraphyChinaChitinozoaMiddle-Late Ordovicianlatest Darriwilian to SandbiantaxonomyDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).
