This altogether created challenging environments for fossilization and preservation of native biota. Consequently, well preserved Oligocene fossils are infrequent worldwide and just as rare in the Central Paratethys. The well-preserved Rupelian (Early Oligocene) diatomites from the Skole Nappe, the external unit of the Outer Carpathians in southeastern Poland were deposited in the Central Paratethys. In some samples, in addition to diatoms, sediments also contain a great diversity of other silicified micro- and nannofossils. Here we report our findings of silicoflagellates (fifteen taxa from five genera), two rotosphaeridians, and several morphotypes of fossil scales, some of uncertain taxonomic affinity. Among silicoflagellates, the most common are species from genera Corbisema (C. triacantha, C. hastata, and C. apiculata) and Dictyocha (D. clinata and D. fibula). We also recovered scales of rotosphaeridians (Pinaciophora and possibly Rabdiophrys) and remains of organisms of uncertain affinity (Clathropyxidella and Macrora) often reported together with silicoflagellates. All of these taxa are the first reports for the Central Paratethys. Silicoflagellate species composition is consistent with the datums derived from other fossils. Silicoflagellates, marine diatoms and archaeomonads suggest a neritic depositional environment.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"40 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141688857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of water “blooms” by euglenoids occurs during accelerated development and intensive cell division of these organisms. Euglenoids outcompete other microalgae and produce significant biomass under favorable conditions. The ability to produce temporal, reproductive and protective cysts also contributes to rapid bloom formations. Our observations suggest that their features probably make them model organisms for observing environmental changes in small water bodies. So far, little attention has been given to the species-dependent color variation of euglenoid blooms. Long-time research on euglenoid taxonomy, biogeography and habitat observations allow observers to recognize different blooms depending on the species causing the phenomenon: Euglena sanguinea, E. mutabilis, E. clara, E. hemichromata, E. geniculata, E. agilis, Euglenaria anabaena, Euglenaformis chlorophoenica, Monomorphina pyrum, Phacus pleuronectes, Ph. orbicularis, Lepocinclis ovum, Trachelomonas volvocina, T. volvocinopsis and T. caudata.

The taxonomy and phylogeny of the southern genus Gondwania have been analyzed based upon fieldwork in Antarctica, Patagonia, New Zealand and Tasmania and subsequent studies including molecular methods. Five species are accepted in the genus Gondwanea including G. inclinans and G. joannae that are combined into the genus. Two species are included in the neighboring new genus Transdrakea, T. alacalufes, a saxicolous species from Patagonia, which is described as new to science and T. schofieldii. Based on molecular data, Austroplaca imperialis is described as a new species to accommodate Patagonian specimens previously named G. regalis. Even though morphologically very similar, the two species are distinct based on molecular and chemical characters and distribution. Gondwania and Transdrakea are chemically homogenous with parietin as the very dominant compound; Transdrakea has a very reduced thallus, whereas Gondwania includes species with crustose thalli, as well as species with fruticulose growth habits. G. inclinans and G. cribrosa are only known from Australia/New Zealand. G. regalis, G. joannae and T. schofieldii are only known from Antarctica. G. sublobulata is confirmed from Patagonia and the Falkland Islands, but Antarctic specimens previously named G. sublobulata belong to G. joannae. G. sejongensis is shown to be a synonym to G. joannae. A key to Gondwania and Transdrakea species is presented.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the United States, it is estimated that 80–90% of species diversity in national parks is presently unknown. Therefore, contemporary biodiversity inventories are critical for conservation, management and establishing baselines for future comparisons. Ongoing efforts to characterize lichen diversity highlight diverse and robust communities in a number of national parks in the USA. In arid regions of the western USA facing ecological transformations, lichens can play a pivotal role for monitoring these changes. Lichen diversity in Bryce Canyon National Park (BRCA) in southern Utah, USA remains nearly completely uncharacterized, despite nearly 100 years as a federally protected area. Our study aims to provide a critical perspective into the lichen diversity of BRCA. Using a metabarcoding community sampling approach, we documented 215 candidate lichen-forming fungal species distributed across ecologically distinct sites in BRCA. At each sampled site, species richness ranged from 104 to 133 species, with no more than 20% shared species among the three sites. The limited overlap between collection sites suggests that BRCA harbors greater diversity than initially thought. We document a number of sensitive lichens, particularly Usnea spp. and Ramalina sinensis, that should be monitored as air pollution, land use, and impacts of climate change affect biological communities in the park. The inventory also includes unknown species and other species that have not been documented in the western USA. While our DNA-based inventory highlights strikingly rich lichen diversity, future voucher-based collections will be essential for robust taxonomic determinations.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":" 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
