ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Na Ilha Cardosa, no sistema lagunar de Maricá-RJ, Brasil, foram realizados levantamentos florísticos, com ênfase para as lenhosas, e diagramas de perfil da vegetação de dois terrenos adjacentes: um terreno de sedimentos arenosos quaternários e outro de tabuleiro. Em cada área foi marcado um transecto de 2 x 60m, sendo amostrados todos os indivíduos lenhosos com DAS ³ 2,5 cm. Foram amostrados 276 indivíduos lenhosos e herbáceos pertencentes a 69 espécies de 33 famílias. Encontrou-se uma diferenciação florística entre as duas áreas expressa nos percentuais de espécies e famílias exclusivas a uma das áreas, e nas famílias com maior riqueza de espécies, assim como diferenças estruturais relativas à densidade, largura da copa, proporção de árvores e lianas e presença de ramificação basal do caule. As formações estudadas apresentaram, florística e fisionomicamente, semelhanças com florestas de restinga. Foram discutidas a adequação da largura e critério de inclusão utilizados para o perfil. O diagrama de perfil foi considerado um instrumento útil no estudo e comparação de estruturas fisionômicas florestais.

In the Cardosa Island, located in the Maricá lagoon system, a floristic survey (especially of woody plants) was carried out and profile diagrams were drawn in order to compare the vegetation of two contiguous areas: an area on quaternary sandy terrain and other on the top of a small hill (Table-land). In each area a 2 x 60m transect was delimited and every shrub, tree or liana with diameter at the base of the stem (DSB) ³ 2,5cm inside of it was recorded and drawn. 276 herbaceous and woody individuals, belonging to 69 species and 33 families, were sampled. The percentage of species and families restricted to one area , and the structural features relative to density, crown width, proportion of trees and lianas and the presence of basal ramification of the stem showed differences between the two areas. Both formations showed floristic and physiognomic similarities with restinga's forests. The adequacy of the transect width, as well as of the minimum DSB used in the profile diagrams were also discussed. The profile diagram was considered an useful instrument for the study and comparison of forests physiognomic structures.

The composition and structure of the edaphic macroarthropod community of these two sites were comparatively studied. The results obtained show that the total densities in the plantation of C. robusta can be higher than in the primary forest. Even though, contrarily to the observed in the forest, this community is characterized by the dominance of some non social groups and by the concentration of most of its individuals in the litter layers. As a consequence, the entire community is more susceptible to seasonal variations in density. Thus, these results emphasize the importance of the leaf litter in providing habitat, food as well as more stable microclimatic conditions for the macroarthropods community. For this reason it is importam to avoid any kind of land management that takes the litter from the soil.
