Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

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

ECP-Social: uma proposta de avaliação da performance social para negócios sustentáveis

Este artigo apresenta o modelo ECP-Social, cuja proposta é identificar a performance social empresarial a partir de um framework de indicadores. A premissa de que a performance social é resultante de um comportamento empresarial frente a pressões da estrutura da indústria e de choques externos a ela delineia o modelo, que conta ainda com uma ferramenta para a sua operacionalização, por meio da qual se identifica o comportamento social, confrontado que, na seqüência, com a estrutura da indústria, gerando o perfil social empresarial. O modelo permite colherem-se informações que permitem a tomada de decisão em relação ao gerenciamento do impacto social

Qualidade pós-colheita de melão 'Orange Flesh' minimamente processado armazenado sob refrigeração e atmosfera modificada Postharvest quality of fresh-cut 'Orange Flesh' melon stored under refrigeration and modified atmosphere

Melões 'Orange Flesh' minimamente processados foram armazenados por 8 dias sob refrigeração (6 &plusmn; 1ºC e 90 &plusmn; 5% UR) e atmosfera modificada (passiva e ativas: 5% O2 + 5% CO2 e 2% O2 + 10% CO2). As variáveis pH, acidez titulável, sólidos solúveis e acetaldeído não foram influenciadas pelas atmosferas estudadas. Aumentos na concentração de CO2 ocorreram ao logo do armazenamento, sendo que a atmosfera modificada ativa (2% O2 + 10% CO2) foi mais eficaz no controle da produção de CO2 até o quarto dia de armazenamento.<br>Fresh-cut 'Orange Flesh' melons were stored for 8 days under refrigeration (6 &plusmn; 1ºC e 90 &plusmn; 5% RH) and modified atmosphere (passive and active: 5% O2 + 5% CO2 and 2% O2 + 10% CO2). The variables pH, titratable acidity, soluble solids and acetaldehyde were not affected, differently, for the atmospheres studied. Increase in CO2 concentration occurred over the storage period. Active modified atmosphere (2% O2 + 10% CO2) was the most effective in controlling the CO2 production until the fourth day of storage
