Part of this biodiversity is within protected areas. The development of online databases in the last years greatly improved the available biodiversity data. However, the existing databases do not provide information about the protected areas in which individual plant species occur. The lack of such information is a crucial gap for conservation actions. This study aimed to show how the information captured from online databases, cleaned by a protocol and verified by taxonomists allowed us to obtain a comprehensive list of the vascular plant species from the Parque Nacional do Itatiaia, the first national park founded in Brazil. All existing records in the online database JABOT (15,100 vouchers) were downloaded, resulting in 11,783 vouchers identified at the species level. Overall, we documented 2,316 species belonging to 176 families and 837 genera of vascular plants in the Parque Nacional do Itatiaia. Considering the whole vascular flora, 2,238 species are native and 78 are non-native. New information The Parque Nacional do Itatiaia houses 13% of the angiosperm and 37% of the fern species known from the Brazilian Atlantic Forest. Amongst these species, 82 have been cited as threatened, following IUCN categories (CR, EN or VU), seven are data deficient (DD) and 15 have been classified as a conservation priority, because they are only known from a single specimen collected before 1969.

A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of Parque Nacional do Caparao (PNC) was previously built using online databases and published on the website Catalogo de Plantas das Unidades de Conservacao do Brasil. Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states. New information Parque Nacional do Caparao houses 8% of the land plant species endemic to the Brazilian Atlantic Forest, including 6% of its angiosperms, 31% of its lycophytes and ferns and 14% of its avascular plants. Twelve percent of the threatened species listed for the State of Espirito Santo and 7% listed for the State of Minas Gerais are also protected by PNC. Surprisingly, 79% of the collections analysed here were carried out in Minas Gerais, which represents just 21% of the total extension of the Park. The compiled data uncover a huge botanical collection gap in this federally-protected area.

Fragmentation and loss of habitat are considered to be the main causes for the decrease in biological diversity in tropical forests. This study aims to evaluate the size and edge effects on tree physiognomy and on the bryophyte community structure in relation to richness, composition, and distribution of ecological groups. Ten forest fragments from the Murici Ecological Station, in the state of Alagoas (Brazil) were studied. In each fragment 10 evenly spaced plots were delimited along four 100 m transects located perpendicularly to the border. One hundred and six species were found, of which 56 were liverworts and 50 were mosses. Results showed that flora impoverishment and other variations in the bryophyte community structure are related to fragment size. Shade epiphytes were the most affected. An ‘edge effect’ was not detected in this study. Vegetation physiognomy parameters contributed partially to the bryophytes’ responses. Diameter at breast height, height, and the density of trees were both positively correlated with bryophyte richness, while canopy openness was not. Our results suggest that the larger fragments are better structured physiognomically, i.e. the trees are taller and have larger diameters, which are probably important factors in enabling them to retain a rich bryophyte flora.
