O Sistema de Informação Científica é uma plataforma de pesquisa que tem por objetivo facilitar o acesso à informação científica disponível em diferentes sistemas on-line. A informação é apresentada em uma página única e permite ao usuário o acesso direto à sua fonte primária. A plataforma é destinada principalmente a pesquisadores e estudantes universitários que buscam encontrar, de maneira rápida e eficiente, informações que podem dar suporte a seus estudos. Entretanto, o sistema é aberto para consulta a todos os públicos.

Também foi apresentado o Sistema de Informação sobre Interações Abelhas - Plantas no Brasil tem por objetivo reunir informações existentes sobre interações entre abelhas e plantas para facilitar as decisões sobre polinização de culturas e conservação de abelhas e plantas. Os dados das interações foram obtidos de levantamentos de abelhas nas flores e de trabalhos que utilizaram a análise polínica como ferramenta para identificação de fontes florais utilizadas por abelhas, realizados em diversas regiões do país e disponíveis em dissertações, teses e artigos, no âmbito do subprojeto "Avaliação do status atual das interações plantas-polinizadores", sob a coordenação da Profa. Dra. Astrid de M.P. Kleinert do Instituto de Biociências da Universidade de São Paulo. O sistema apresenta como resultado a interação de mais de 900 espécies de abelhas com mais de duas mil espécies de plantas.
No evento também foi ressaltado o papel da RNP (Rede Nacional de Ensino e Pesquisa) que além dos serviços de conectividade, oferece ao CRIA uma infraestrutura física para os seus servidores em seu Internet Data Center, com garantias de alta disponibilidade, segurança e operação ininterrupta.
Esperamos com esses sistemas reforçar a importância do conhecimento e conservação das abelhas para a manutenção da biodiversidade e produção de alimentos.

A herbarium can be defined
as a collection of preserved samples of plants and fungi and associated data.
In a herbarium, specimens (samples) of plants and fungi collected in the field
are normally dried and mounted on sheets of paper and labelled with essential
data, including who collected the sample, when and where
it was collected, what was collected (the scientific name of the
plant or fungi) and who identified the sample. The identification
of the sample can be informed as part of the field data or can be determined
later by experts. As taxonomy evolves with time, scientific names, and
sometimes even municipalities and country names must be updated. A dynamic
curation of specimens and associated data must be in place.
Through herbaria data one
can analyze species’ distribution through both time and space. Studies based on
this data are important for a number of applications such as education,
research, and conservation. A herbarium is a center of documentation of the
biodiversity of the past and an important instrument to model the biodiversity
of the future. If prepared and maintained correctly, these specimens hold their
scientific value for centuries. Having a sample associated to the data enables
reassessing its identification and perhaps carrying out analysis that may not
have existed when the sample was collected. An example is DNA sequencing of
historical specimens. This undoubtedly increases the importance of a herbarium.
Herbaria exist since 1635,
with the establishment of the Museum National d'Histoire Naturelle in
Paris, France, but the first herbaria in Brazil were established in the early
19th century. It is important to compare Brazil’s largest herbaria with
those in Europe and USA. The largest herbaria in the world, such as Muséum
National d'Histoire Naturelle and New York Botanical Garden (NY), hold about 8
million specimens, while Brazil’s two largest herbaria, Botanical Garden of Rio
de Janeiro and our National Museum only hold about 600 thousand specimens each.
However, Brazil has about 200 active herbaria that together hold about 8
million specimens. Integrating the data of Brazilian herbaria through a
network, enabled by the development of information and communication
technology, made it possible for Brazil to have an on-line herbarium with
significant holdings, comparable to large herbaria worldwide.
This e-infrastructure is
enabling the consolidation of a collaborative network of experts totally
engaged in improving the quality of the holdings and of on-line data. This
network also is involved with 95% of the botany related graduate courses of the
country, influencing research and education of future botanists.
Brazil’s Virtual Herbarium today – some numbers
The network integrates 193
datasets from 130 Brazilian herbaria and 20 herbaria from Europe and the USA,
with holdings of samples collected in Brazil.
Figure

Virtual Herbarium (see http://inct.splink.org.br/showNetwork)
Together these data providers hold over 7 million samples and share
about 5.6 million data records and 1.5 million images of more than 78
thousand distinct species (all with accepted names). Besides integrating
new herbaria to the network, it is still necessary to invest in
digitization.
An important indicator is the movement of data (entry and removal) in
the network, showing its dynamic nature. Figure 2 presents monthly
averages for both total online records and total georeferenced records.
The red line shows the number of data providers per month.
Figure 2. Monthly averages of data entry (see http://splink.cria.org.br/indicators)One can see the constant increase of data and data providers, with
the exception of October 2015 when one of Brazil’s largest herbaria
decided to remove its data because they felt that they were losing
visibility. This shows that there are still some cultural and
institutional barriers to overcome. As for usage, more than 1.7 billion data records were used between
October 2012 and May 2017. The year 2016 indicated an average usage of
1.2 million records a day.

Brazil’s Virtual Herbarium and OCSDNet
Within the context of the Open and Collaborative Science in
Development Network (OCSDNet), Brazil’s Virtual Herbarium sought to
understand the impact of data sharing and open collaboration for both
data providers and users. For this purpose, the following activities
were carried out:
Application of a semi-structured questionnaire and SWOT analysis
indicating strengths, weaknesses, opportunities, and threats concerning
Brazil’s Virtual Herbarium;
Email sent out to voluntary contributors of two on-line tools –
annotation system and geographic distribution modeling workflow
(BioGeo);
Analysis on blocked data, asking data providers the reasons why data was blocked; and,
Analysis on data users and usage of Brazil’s Virtual Herbarium.
Impacts
The greatest impact of this OCSDNet project was on the herbaria (data
providers) that had the opportunity to reflect on outcomes derived from
their participation in the network and share their thoughts with other
herbaria. This has made previous “herbaria that share data” into a
robust network. The human network established is, by far, the greatest
impact of this project and is the center of its innovative character. It was found that on-line voluntary contributions through the annotation system and BioGeo (see http://biogeo.inct.florabrasil.net)
had their own research as their motivation for participation. However,
these contributors helped to improve data quality. The distribution
models were also reported to be used to determine new areas for field
collections and as such, these users also contributed in sharing new
data records. One of the aims of the Virtual Herbarium was to promote e-science. An
example of its impact on taxonomy and the identification of new species
is shown in Figure 4.
Figure
4. Number of angiosperms species described by Brazilian (orange line)
and foreign (grey line) scientists from 1990 to 2013. (Canhos, et al.
2015)).The growth of the number of angiosperm species in Brazil described by
Brazilian scientists is clear. The availability of data through
Brazil’s Virtual Herbarium and the network of specialists established
surely contributed to this change.
An important characteristic of this network, the geographic
distribution of participating herbaria and their association to graduate
programs, also has a great impact on education and training of future
researchers, not only as to tools and data usage, but also as to the
promotion of open sharing of data and knowledge.
When developing the Virtual Herbarium, its main aim was to make data
available on-line to all interested. This is not an easy task as it
implies a cultural change as well. In the beginning of the project, it
was not clear what the data provider, in this case, the team responsible
for the herbaria, would gain from this. To most, it seemed to involve
much more work with very little to gain. Due to the reflection carried
out through the OCSDNet project, it became clear that a lot is gained
from organizing and sharing one’s own data. Besides receiving credit for
their work, most data providers also became intensive users of data and
were able to also share knowledge and benefit from other users’
knowledge to improve their own data.
Our team therefore concludes that providing data is not a one-way
road. Besides using and benefiting from feedback mechanisms, most
herbaria found that visits to the facilities increased as did new
collaborative projects and research. Most benefited from an increase in
usage and in awareness of the data’s importance. With time, this also
brought an increase in their recognition and support from their own
institution.
