The flora of south-eastern Mato Grosso State (Brazil): a review of herbarium collections.

The diversity and richness of the Brazilian flora are documented in herbarium collections. When areas are deforested, but not documented, we lose both flora and the opportunity to know which species occupied those areas. The south-eastern mesoregion of Mato Grosso State, comprising 22 municipalities, has undergone the loss of native vegetation cover, accelerated by the substantial expansion of agribusiness.

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area.

Background: Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity.

[Maria Bandeira: a pioneering botanist at the Botanic Garden of Rio de Janeiro].

This article sheds light on Maria Bandeira, the first female botanist to work at the Botanic Garden of Rio de Janeiro. She was active in the 1920s, but is absent from the historiography and little cited in the scientific literature. The significant number of plant, fungus, and lichen specimens she collected, her capacity to reach far-flung places, her extensive correspondence with foreign experts, and her studies at Sorbonne are all sources for the analysis of the way botany was practiced and the social networks at play in science at the time.

[Teaching, research, and extension service: botanist Honório da Costa Monteiro Filho].

The article revisits the work of Honório da Costa Monteiro Filho, highlighting his contribution to the study of economic botany and the taxonomy of Brazilian Malvaceae. Many of his seventy articles, are still cited. Yet little is known about his important role in educating agronomists involved with Brazilian flora and the creation of the Botanical Society of Brazil.

Evidence for conservation and sustainable use in a fragment of the Atlantic forest in southeastern Brazil by a traditional human group.

The use of forest resources by a rural community adjacent to a Biological Reserve was examined using quantitative methods based on the consensus of six local specialists. Plants with trunk diameters at 1.3 m above soil level (DBH) ≥ 5 cm were sampled in 0.

[Research in ethnobotany and the return of systematized knowledge to the community: a complex issue].

How should information gathered in ethnobotanical research be returned to the social environment where it was generated? What should be taken to the community? These questions motivated the accompaniment of two ethnobotanical studies and their respective proposals for how to return to the community the knowledge associated to plants, systematized by the scientist. It is common for research data to be returned to a community by means of manuals, information booklets, illustrated lists of plants, lectures and courses. Nevertheless, other forms have been prepared that characterize an exchange of knowledge among the scientist and the community, with mutual gains.
