Snails of the family Lymnaeidae act as intermediate hosts in the biological cycle of Fasciola hepatica, which is a biological agent of fasciolosis, a parasitic disease of medical importance for humans and animals. The present work aimed to update and map the spatial distribution of the intermediate host snails of F. hepatica in Brazil. Data on the distribution of lymnaeids species were compiled from the Collection of Medical Malacology (Fiocruz-CMM, CPqRR), Collection of Malacology (MZUSP), “SpeciesLink” (CRIA) network and through systematic surveys in the literature. Our maps of the distribution of lymnaeids show that Pseudosuccinea columella is the most common species and it is widespread in the South and Southeast with few records in the Midwest, North and Northeast regions. The distribution of the Galba viatrix, G. cubensis and G. truncatula showed a few records in the South and Southeast regions, they were not reported for the Midwest, North and Northeast. In addition, in the South region there are a few records for G. viatrix and one occurrence of Lymnaea rupestris. Our findings resulted in the first map of the spatial distribution of Lymnaeidae species in Brazil which might be useful to better understand the fasciolosis distribution and delineate priority areas for control interventions.

Field collection and herbaria data did not allow to quantify the diversity of aquatic plants from Northern Brazil, so we could not detect biogeographic patterns. Therefore, our objectives were to identify and quantify the aquatic macrophytes of North Brazilian states, analyzing herbaria data plataforms (SpeciesLink and Flora do Brasil). The checklist was produced by bibliographic search (articles published between 1980 and 2000), herbaria collections of the platforms SpeciesLink and Flora do Brasil and field expeditions, where we utilized asystematic sampling. We also analyzed the floristic similarity of aquatic macrophytes among Northern Brazil, wetlands of distinct Brazilian regions and the Neotropics. We recorded 539 species, of which 48 are endemic to Brazil. The states with highest number of species were Amazonas and Pará, independently on platform. The most represented families were Poaceae (89 species), Podostemaceae (55), Cyperaceae (50) and Fabaceae (47). We highlight the unprecedent richness of Podostemaceae, due to our own field collection efforts on favorable habitats, 25 species being endemic. Emergent and/or amphibious plants (515) were dominant in total species richness and were best represented in lotic habitats. We found significant differences in richness and floristics among states, obtained from the platforms. There is floristic similarity among Northern states and other Brazilian wetlands. In conclusion, we observed a rich aquatic flora in Northern Brazil, in spite of scarcity of records for Acre, Rondonia and Tocantins; we highlight the unprecedent number of endemic species of Podostemaceae (25) and contrasting richness between SpeciesLink and Flora do Brasil.

O gênero Dalbergia L.f., pertencente à família Leguminosae-papilionoideae, compreende cerca de 250 espécies. Muitas são cultivadas por variadas finalidades, como Dalbergia nigra (Vell.) Allemão ex Benth. (Jacarandá-cabiúna) e Dalbergia spruceana Benth. (Jacarandá) para produção de madeira; Dalbergia subcymosa Ducke (Verônica) pelo uso medicinal e Dalbergia ecastaphyllum (L.) Taub (Rabo-de-bugio) para produção de própolis vermelha. Dessa forma, objetivou-se realizar um levantamento das espécies de Dalbergia para o estado do Pará. Para tanto, as informações foram extraídas do acervo do Herbário IAN utilizando o sistema BRAHMS (Botanical Research And Herbarium Management System) e da plataforma online SpeciesLink filtrando os registros para o estado do Pará e para o gênero Dalbergia. O mapa de distribuição foi feito através da ferramenta mapCRIA da plataforma SpeciesLink utilizando as coordenadas geográficas de coleta. A partir do levantamento constatou-se a presença predominante de Dalbergia monetaria L.f. (Verônica) e Dalbergia inundata Spruce ex Benth (Cabiúna-de-estribo) no acervo das bases de dados. Em relação aos locais de coleta, Santarém apresentou maior número de registros, seguido de Oriximiná e Bragança. Outro fator relacionado é o adensamento de espécies em áreas de influência fluvial. Logo, foi possível demonstrar a biodiversidade das espécies no estado, a qual poderá contribuir com estudos botânicos e revisões taxonômicas do referido gênero na região.
