    Abstract: The present study aimed to examine the phenolic content and evaluate the antimicrobial and antioxidant potential of ethanol extracts from the moss species Phyllogonium viride Brid. on the pathogenic bacteria Salmonella enterica serovar enteritidis , Staphylococcus aureus , Listeria monocytogenes and Escherichia coli , and the pathogenic fungi Candida albicans and Cryptococcus neoformans . The antimicrobial activity was determined from Minimum Inhibitory Concentration (MIC) Minimum Bactericidal Concentration (MBC) and Minimum Fungicidal Concentration (MFC). Antioxidant activity was determined by the DPPH method. Folin‐Denis reagent was used for the content of total phenolics and flavonoids and HPLC‐DAD for identification of phenolic compounds. The results showed that bacteriostatic and bactericidal activities occurred at concentrations ranging from 9.76 μg/mL–78.13 μg/mL among all evaluated microorganisms. These values, considering the criteria used, suggest the P. viride extract as a potent antimicrobial. For antioxidant activity, P. viride extract was considered weak. Analysis of the phenolic content showed a wide range of compounds, with Kaempferol (0.41 mg/g) being the major compound, followed by t ‐cinnamic acid and caffeic acid (0.17 mg/g). Although P. viride is a species of moss not yet referenced in scientific publications of biotechnological interest, it has shown promising potential for further studies and possible application as an antimicrobial of natural origin.

    Abstract: The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis , concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora.

    Abstract: Esta pesquisa teve como tema o Projeto Escolas Conectadas como parceiro na formação continuada em Educação Ambiental de educadores do Brasil e, como objetivo de pesquisa, buscou-se analisar como o Projeto Escolas Conectadas auxilia na formação continuada em Educação Ambiental de educadores do Brasil, com foco no curso Água: gotas de conscientização. Como referencial teórico, embasou-se em diferentes autores(as) de Educação Ambiental e formação de professores, como Albanus (2008) e Nóvoa (2001). Numa abordagem qualitativa, mas com expedientes de apoio quantitativos, desenvolveu-se uma pesquisa com a plataforma digital do Projeto Escolas Conectadas – Fundação Telefônica Vivo, com foco no curso Água: gotas de conscientização – edição 2018. Utilizou-se a técnica de observação participante com 409 cursistas inscritos, através da mediação do curso e de análise documental. Constatou-se que o Projeto Escolas Conectadas auxilia na formação continuada em Educação Ambiental de educadores do Brasil, possibilitando sua capacitação. Conclui-se que a edição investigada viabilizou aprendizagens por meio das trocas de experiências com pares residentes em diferentes estados brasileiros (favorecendo a compreensão das singularidades do meio ambiente considerada cada região, bem como acerca da importância da água), promoveu inspirações para a prática na sala de aula (fomentando não só aos educadores participantes do curso, como também aos seus alunos, o respeito, o zelo e o apreço pela natureza) e suscitou visão crítica sobre as questões analisadas no decorrer da formação.

    Abstract: Introdução: pesquisas recentes mostram que musgos contêm substâncias com atividade biológica evidenciando um nicho a ser explorado. Objetivo: avaliar a produção científica globalem relação à atividade antibacteriana de musgos, no período de 1992 a 2022.Metodologia: análise bibliométrica quali-quantitativa dos artigos recuperados da base Web of Scienceutilizando osoftwareExcel 2018 e VOSviewer, respectivamente.Resultados: 92 artigos foram recuperados e demostram uma tendência crescente de publicações ao longo dos anos, com uma maior concentração nos últimos 3 anos. Turquia, Sérvia, e Índia, tiveram o maior número de publicações e citações. Sérvia e Índia têm sido parceiros frequentes em colaborações internacionais com co-autorias juntamente com Dinamarca e Vietnã, respectivamente. Natural Product Communicationse Fitoterapiaforam as revistas mais utilizadas para tonar público os resultados. A análise de palavras-chave sugeriu que as pesquisas concentram-se em estudos sobre atividades biológicas e químicas envolvendo principalmente hepáticas, sendo as do gênero Marchantia spp. e Plagiochasmaspp. as mais utilizadas. Pottiaceae e Sphagnaceae foram as famílias de musgos com mais espécies estudas. A espécie Hypnum cupressiformeHedw. é a que obteve um maior número de publicações, 8 no total. As 104 espécies que apareceram nos artigos recuperados não se encontram ameaçadas de extinção no Brasil e no mundo e 17 delas possuem registro de ocorrência no Brasil. Conclusão: a atividade antibacteriana em musgos representa uma parcela pequena das pesquisas na área, apesar do seu potencial uso como antibacteriano, o que enaltece e evidencia a necessidade de estudos que abordem esse tema.

    Abstract: We examined the relationship between reproductive allocation and vegetative growth in three monoicous sexual systems of bryophytes. The sexual systems show a gradient of increasing distance between the sexes, from gonioautoicous to cladautoicous to rhizautoicous. Here, we investigated the following two hypotheses: (1) reproductive allocation differs between sexes and sexual systems, and male reproductive allocation increases with increasing distance between male and female gametangia; and (2) reproductive allocation is negatively related to vegetative growth. Methods We sampled the three sexual systems, represented by three moss species of the genus Fissidens in the Atlantic Forest of Southeastern Brazil. Ramets were washed in the laboratory; the reproductive structures were detached from the vegetative ramets and sorted regarding sex and individual, dried at 70 °C for 72 h, and weighed in an ultramicrobalance. We calculated the mean reproductive and vegetative mass and reproductive allocation and used generalized linear models to test our predictions. Key Results Reproductive allocation differed between species and sexes. It was higher in the rhizautoicous than in the cladautoicous and gonioautoicous species. Mean reproductive allocation was greater in males than in females of the rhizautoicous species, greater in females than males of the cladautoicous species, and did not differ between the sexes in the gonioautoicous species. Estimates of reproductive and vegetative mass were positively related in females of the rhizautoicous species. Vegetative mass was not related to reproductive allocation in the gonioautoicous species, but negatively related to reproductive allocation in the male and female branchlets of the cladautoicous species and in the female ramets of the rhizautoicous species. Conclusions The reproductive allocation patterns differ between the rhizautoicous species and the ‘truly’ monoicous species, with shorter intersexual distances, which implies that our hypotheses were supported only in part. We suggest that the hypotheses should be reformulated and tested further by comparing ‘truly’ monoicous species with dioicous species and by including other genera.

    Abstract: Resumo Sphaerocarpos muccilloi (Sphaerocarpaceae, Marchantiophyta) foi descrito em 1981 como uma espécie endêmica e única da família no Brasil. É considerada Criticamente Ameaçada (CR) no estado do Rio Grande do Sul, Brasil, de acordo com a “Lista Vermelha das espécies da flora ameaçadas do estado do Rio Grande do Sul”. S. muccilloi é citado apenas para 3 localidades: Porto Alegre, São Leopoldo e Ivoti (coletado entre 1963 e 1977), todas áreas hoje altamente antropizadas, sendo a última coleta ocorrida há mais de 40 anos. Após uma revisão em herbários e coletas em campo S. muccilloi foi recoletado no ano de 2017 no Bioma Pampa (municípios de Santana do Livramento - Área de Proteção Ambiental do Ibirapuitã; Mata e Santa Vitória do Palmar). Outra espécie, Sphaerocarpos texanus, não registrada para o Brasil, foi reportada para o estado do Paraná. Estes novos registros fornecem importantes informações sobre a ocorrência e distribuição da família no Brasil. Para S. muccilloi, estes novos registros indicam que a distribuição desta espécie ameaçada é mais ampla. Estes dados subsidiarão a revisão da lista de espécies ameaçadas do Rio Grande do Sul e Brasil, além de subsidiar estratégias de conservação.
