    A total of 34 bryophyte species were identified (25 hepatics, 9 mosses) from restinga at Setiba State Park, Guarapari Municipality, EspĂ­rito Santo State, Brazil. Several species reported previously from restinga appear to be erroneous records, based on misidentification

    Sofrendo influências de outros ecossistemas, tais como o Cerrado e a Floresta Amazônica, o Pantanal de Mato Grosso constitui um ecossistema único. Embora sua flora fanerogâmica seja relativamente bem conhecida, a brioflora ainda necessita ser estudada mais profundamente. Fazendo parte da bacia do bio Paraguai e localizado a 94,8km de Cuiabá nas coordenadas 16º15'24"S e 56º36'24"W, o Município de Poconé possui uma população de cerca de 30.000 habitantes. Foram realizadas coletas briológicas nos anos de 1984, 1999 e 2000, tendo sido encontradas 12 espécies pertencentes a 12 famílias de Bryophyta e 10 espécies distribuídas em duas famílias de Marchantiophyta, sendo Lejeuneaceae a melhor representada, com oito espécies. Foram encontradas cinco novas ocorrências para o região Centro-Oeste: Trichosteleum fluviale (Mitt.) Jaeg., Frullania tetraptera Nees & Mont., Lejeunea glauscescens Gottsche, Lejeunea calcicola Schuster, Lejeunea caespitosa Lindenb. São ainda citadas nove novas ocorrências para o Estado do Mato Grosso: Hyophila involuta (Hook.) A. Jaeg., Groutiella apiculata (Hook.) Crum & Steere, Fabronia macroblepharis Schwaegr., Trichosteleum fluviale (Mitt.) Jaeg., Frullania arecae (Spreng.) Gottsche, Frullania tetraptera Nees & Mont., Lejeunea glauscencens Gottshe, Lejeunea calcicola Schuster e Lejeunea caespitosa Lindenb. Lejeunea calcicola Schuster é citada pela segunda vez para o Brasil.Under the influence of outer ecosystems, such as the Cerrado and Amazon rain forest, the Pantanal of Mato Grosso is a unique ecosystem. Otherwise his fanerogamic flora is well known, the bryoflora is yet to be properly discovered. As part of Paraguai river basin and located at 94.8km from Cuiabá at 16º15'24"S and 56º36'24"W, the county of Poconé has a population around 30,000 hab. Colects were taken in 1984, 1999 and 2000. Among the Division Bryophyte 12 species in 12 familie were founs. In the Division Marchantiophyta 10 species in two families were found. The better represented family was Lejeuneaceae, with eight species. Five new occurrences to the Centro-Oeste region were found: Trichosteleum fluviale (Mitt.) Jaeg., Frullania arecae (Spreng.) Gottsche, Frullania tetraptera Nees & Mont., Lejeunea glaucescens Gottsche, Lejeunea calcicola Schuster, Lejeunea caespitosa Lindenb. and nine new occurrences to Mato Grosso State were found: Hyophila involuta (Hook.) A. Jaeg., Groutiella apiculata (Hook.) Crum & Steere, Fabronia macroblepharis Schwaegr., Trichosteleum fluviale (Mitt.) Jaeg., Frullania tetraptera Nees & Mont., Lejeunea glaucescens Gottshe, Lejeunea calcicola Schuster and Lejeunea caespitosa Lindenb. Lejeunea calcicola Schuster is mentioned for the second time to Brazil

    The Pantanal Ecosystem is still poorly known in its bryoflora, with almost no literature and very few collections. This paper represents a contribution to better understand the bryophyte diversity in the brazilian Pantanal. With a population around 85,857 and 27,462.38 Km2 and located at 16º11’42" S and 57º40’51" W, the Cáceres county is totally inserted in the Pantanal ecosystem. Its bryoflora has never been studied before. Here are presented 5 liverworts and 21 mosses, of which Barbula indica (Hook.) Spreng., Calymperes palisoti Schwägr., Fabronia ciliaris var polycarpa (Hook) W.R.Buck, Taxiphyllum taxirameum (Mitt.) M. Fleisch. are cited for the first time for Mato Grosso. Fissidens dissitifolius Sull. is cited for the first time to Brazil and Tortella lilliputana (Müll. Hal. ex G. Roth) R.H. Zander, is cited for the second time to Brazil. The data suggest how poorly known the area still remains and more studies are in need for the Pantanal and Mato Grosso state.O ecossistema Pantanal ainda permanece pouco conhecido do ponto de vista briológico, com poucas coleções e quase nenhuma literatura. Neste contexto, este trabalho apresenta uma inédita contribuição para o conhecimento da diversidade briológica Pantaneira. Com uma população de 85.857 habitantes em 27.462,38 quilômetros quadrados, entre as coordenadas 16º11’42" S e 57º40’51" W, o municípo de Cáceres, está totalmente inserido no ecossistema Pantanal. Sua brioflora nunca foi estudada anteriormente. Neste trabalho apresentamos a ocorrência de 5 hepáticas e 21 musgos, entre os quais: Barbula indica (Hook.)

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
