description The Atlantic Forest biome has suffered in recent years with degradation, due to the increase of anthropic activities, which lead to the main problem of forest remnants, which is the fragmentation, hindering the floristic studies and conservation itself. This thesis had the objective to expand the floristic knowledge of angiosperms within an area of Atlantic Forest in Rio Grande do Norte (RN), through the elaboration of an updated species catalog, using herbarium records, with subsequent analysis of the spatial distribution of collections within the region.The study area selected is the Bonfim-Guaraíra Environmental Protection Area (BGEPA), included in the eastern portion of the RN within the Atlantic Forest domain. We assessed the levels of sampling effort, percentages of remaining forests, and indicated the priority areas for research and conservation within the EPA. We created a georeferenced database of the angiosperm records from herbariua ASE, CESJ, HUCS, HUEFS, JPB, JBRJ and UFRN that are available in online platforms (JABOT and SpeciesLink) totaling 2029 records. Collections distribution points were plotted over maps of the land use and land cover obtained from the MAPBIOMA platform. The first step of this work was performed with the data cleaning of all collection records. After the data cleaning, we had a reduction in the total number of records to 966. Errors with geographical coordinates corresponded to 25.25% of the total, while duplicate records totaled almost 60% of all analyzed data, indicating that the flora of the area is still poorly known and that more than half of the available records are duplicates. The land cover and use map indicated that the Agriculture and Pasture Mosaic class with 20.100,7 ha (47% of the total area), followed by the Forest Formation class with 7.895,3 ha (18.46%) are the largest in BGEPA. In addition, most collections are from the Forest Formation class (43.89%). To check if roadsides were concentrating collections, maps with a buffer along roads were created and it was possible to identify that the most records came from the range between 0.5 km and 1 km of of roads or highways. A checklist was created for all the species present at BGEPA with the georeferenced database totaling 387 species distributed in 269 genera and 86 families. The richest family was Fabaceae, in the Rosideae clade, with 51 registered species. In contrast, the genus with most species was Cyperus (Cyperaceae). Only Eugenia pipensis was identified as endemic to the BGEPA, and only Melocactus violaceus and Cyperus articulatus are categorized as Vulnerable on the threatened redlists. It was confirmed that the two municipalities Nisia Floresta and Tibau do Sul are the most abundant in species, which indicates there is a need for collection in other municipalities of BGEPA, as well as in other undercollected phytophisiognomies.

O domínio Mata Atlântica tem sofrido nos últimos anos com degradações, devido ao aumento das atividades antrópicas, o que leva a um dos principais problemas dos remanescentes florestais, que é a fragmentação, dificultando os estudos florísticos e a conservação em si. O objetivo deste trabalho é relacionar dados espaciais, empregando-se o Sistema de Informações Geográficas (SIG), com dados florísticos dentro de uma área de Mata Atlântica no Rio Grande do Norte. A Área de Proteção Ambiental (APA) Bonfim-Guaraíras (ABG) foi selecionada como área de estudo, já que se insere na porção oriental do Rio Grande do Norte (RN), dentro do domínio da Mata Atlântica. Serão avaliados os índices de esforço amostral, percentuais de remanescentes florestais e indicadas as áreas prioritárias para pesquisa e conservação dentro da APA. Para isso foi criado um banco de dados com 2029 registros georreferenciados de angiospermas dos herbários ASE, CESJ, HUCS, HUEFS, JPB, JBRJ e HUFRN disponíveis em plataformas online (JABOT e speciesLink). A primeira etapa desse trabalho foi realizada com o processo de data cleaning, para limpeza dos registros coletados. Após o processo de data cleaning tivemos uma redução no número total de registros para 966. Os resultados mais expressivos desse processo estão disponíveis no capítulo 1 dessa dissertação. A partir do banco de dados georreferenciado foi possível a criação de um checklist para todas as espécies presente na APA Bonfim-Guaraíra. Foram listadas 387 espécies distribuídas por 269 gêneros e 86 famílias. A família mais abundante foi a Fabaceae do clado das Rosídeas com cerca de 51 espécies registradas. Em contrapartida o gênero como maiores registros foi o Cyperus da família Cyperaceae. Apenas uma espécie foi identificada como endêmica a Eugenia pipensis, e apenas duas com situação vulnerável nas listas de ameaçadas, sendo elas a Melocactus violaceus e a Cyperus articulatus. Confirmou-se que os dois municípios Nísia Floresta e Tibau do Sul são os mais abundantes em espécies, o que indica necessidade de coleta nos outros municípios da ABG, para melhor conhecer sua flora e a situação de suas espécies. 2020-04-03T18:33:32Z 2020-04-03T18:33:32Z 2020-01-29 masterThesis COUTINHO, Joaquim Custódio.
