Description
Criado há mais de um século, o RB compreende atualmente cerca de 750.000 espécimes montados, com forte representação da flora brasileira, principalmente das florestas Atlântica e Amazônica. Quase 100% desses espécimes foram inseridos no banco de dados e imageados e, atualmente, cerca de 17% foram georreferenciados. Este artigo científico concentra-se exclusivamente na coleção de exsicatas de plantas terrestres e algas do RB, que atualmente está aumentando em cerca de vinte a trinta mil espécimes por ano, graças a trabalho de campo, intercâmbios e doações. Desde 2005, diversos projetos nacionais e internacionais foram implementados, melhorando a qualidade e a acessibilidade da coleção. O fator facilitador mais importante nesse processo foi a criação do sistema institucional para coleta e gerenciamento de plantas, denominado JABOT. Como o RB está em constante crescimento, o conjunto de dados é atualizado semanalmente nos portais SiBBr e GBIF.
Os ambientes mais representados são as florestas Atlântica e Amazônica, um hotspot de biodiversidade e a maior floresta tropical do mundo, respectivamente. O conjunto de dados descrito neste artigo contém os dados e metadados de espécimes de plantas e algas da coleção RB e o link para acessar as respectivas imagens. Atualmente, os dados RB estão disponíveis publicamente online em diversos portais de biodiversidade, como nosso banco de dados institucional JABOT, o Herbário Virtual Reflora, o SiBBr e o portal GBIF. No entanto, uma descrição do conjunto de dados RB na totalidade não está disponível na literatura.

Couverture géographique
The majority of specimens were collected in Brazil (ca. 90%) and the country’s most widely represented region is the Southeast, where the herbarium is based (ca. 349.000 specimens, 50% of the total). The south-eastern states of Rio de Janeiro (ca. 189,000 specimens) and Minas Gerais (ca. 90,000) are represented by the largest number of specimens (Fig. 5). It should be noted that most of this region is part of the Atlantic Forest and Rio de Janeiro state is positioned entirely within this biome. North Brazil ranks second in number of specimens and the states of Amazonas and Pará are the best represented, with ca. 29,000 (ca. 4%) and 28,000 (ca. 4%), respectively (Fig. 5). One of the first great plant collectors in the region, especially with regard to Amazonian flora, was Adolf Ducke, who conducted expeditions in the states of Amazonas and Pará, mainly in the first half of the 20th century.

Méthodes d'échantillonnage
The herbarium specimen collection combines specimens from institutional projects, undergraduate and post-graduate research and exchanges or donations from other herbaria. In addition, from 1970 onwards, relevant national projects of flora documentation sent specimens to RB, such as RADAMBRASIL Project (1970-1985) and the Flora Program CNPq (1975-1983, MCT/CNPq 1987). Furthermore, as the official custodian for the Ministry of Environment, RB also receives many specimens from private companies with activities related to environmental impact studies and phytochemical products and most of these specimens are donated in exchange for identification. The institution includes 53 associate researchers and hosts around 550 visiting taxonomists every year, standing out as the most visited herbarium in Brazil. Quality
| Etendue de l'étude | Not described |
|---|---|
| Contrôle qualité | The RB uses the institutional system JABOT to perform all functions regarding herbarium management (i.e. loans, donations, new specimen registration, database management, quality control and web publication). The JABOT is a PostgreSQL database management system with 117 tables specifically created for botanical collections. The data insertion can be made directly into the JABOT interface or via uploading spreadsheets, with controlled and free text fields (Silva et al. 2017). |
Description des étapes de la méthode:
- Plant processing procedures: The herbarium follows the usual procedures for processing specimens (Bridson and Forman 2000, Simpson 2006). Fresh materials are pressed and dried over a stove or in an oven. Once they are dry, specimens are glued on to acid-free paper, with gummed cloth tape or thread for bulky plants. Bryophytes, fungi and lichens are placed into acid-free packets. Algae can also be mounted on acid-free paper with gummed cloth tape or stored in plastic boxes in the case of calcareous algae.
