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.

ABSTRACT This study aimed to identify alterations in gills and hepatopancreas of the crab Ucides cordatus as indicative of environmental contamination in mangrove areas subject to chemical effluents from port activities in Maranhão, Brazil. Samples of gills and hepatopancreas were removed from each animal and fixed in Davidson's solution until the procedure of histological technique. The biometric data (means and standard deviations) of the specimens collected in the study areas indicated that the crabs in the reference area are significantly (P < 0.05) higher and heavier than the crabs collected in the potentially impacted area (port area). Gill alterations (rupture of pilaster cells, dilation of the marginal channel, cuticle rupture and necrosis) and hepatopancreas alterations (abnormal lumen, vacuolized B cells, pycnotic nuclei and necrosis) were significantly (P < 0.05) more frequent in crabs collected in the port area than crabs collected in the reference area. These data indicate that the health of crabs is compromised due to the pollutants present in the mangroves that surround the port area in São Marcos' Bay.

Distribution, longevity and migration of Cyathostominae free living stages have been studied in differents types of climate in the World. Few works exist on this subject in South America. The objective of this research was evaluating survival and migration in Tifton 85 (Cynodon spp. cv. Tifton 85) sward in tropical climate. Fecal plots were monthly placed on pasture Tifton, from September of 2003 to September of 2004. Sward and faeces were collected weekly, at 8 a.m., 1 and 5 p.m. and processed by Baermann technique. L3survival on faeces varied from four to nine weeks in rainy period and from eight to 15 weeks in dry period, with higher recovered in rainy period. In the pasture,larvae longevity varied from two to eight weeks in rainy period and from five to 13 weeks in dry period, with higher L3 recovery in dry period. The multivariable weeks in dry period, with higher L3 recovery in dry period. The multivariable analysis of main components evidenced the influence of time and environmental variables on the number of recovered larvae from faeces and pasture. Climatic conditions influenced the development, survival and migration of infective larvae. L3 were recovered during the three times of collection and no significant difference was observed among three times. The study results demonstrated that in tropical climate conditions Cyathostominae L3 are available on faeces and pasture during whole months of the year

A distribuicao, longevidade e migracao de larvas infectantes de ciatostomíneos de equinos vem sendo estudada em diferentes tipos de clima no Mundo. Poucos trabalhos existem sobre este tema na América do Sul. O objetivo do presente estudo foi avahar a sobrevivencia e a migracao em gramínea Tifton 85 (Cynodon spp. cv.Tifton 85) sob condicoes de clima tropical. Massas fecais foram depositadas mensalmente na gramínea Tifton, no período de Setembro de 2003 a Setembro de 2004.Gramínea e fezes foram coletadas a cada sete dias, as 8, 12 e 17 h e processadas pela técnica de Baermann para recuperacao de L3. Ñas fezes, a sobrevivencia das L3 variou de quatro a nove semanas no período chuvoso e oito a 15 semanas no período seco, com maior recuperacao durante o período chuvoso. Na gramínea, a longevidade das larvas variou de duas a oito semanas no período chuvoso e cinco a 13 semanas no período seco, com maior recuperacao das larvas infectantes no período seco. A análise multivariada de componentes principáis evidenciou a influencia do tempo e das variáveis ambientáis sobre o número de larvas recuperadas das fezes e da gramínea. As condicoes climáticas influenciaram no desenvolvimento, na sobrevivencia e migracao das larvas infectantes. As L3 foram recuperadas durante os tres horarios de coleta e nao se observou diferenca significativa entre os horarios. Os resultados do estudo demonstraram que em condicoes de clima tropical as L3 de ciatostomíneos estáo disponíveis ñas fezes e na pastagem, durante todo os meses do ano
