Introduction
I'm a botanist with a Ph.D. in Comparative Biology from the State University of Maringá. My research is focused on systematics of campo rupestre clades of Melastomataceae. I have published mostly on Microlicia (tribe Lavoisiereae) but I am now expanding my research effort with Melastomataceae to include members of the tribe Marcetieae. Many of these clades are fire-adapted with major diversification that coincided with the origin of the Cerrado biome within the last 10 million years.

A new species of Microlicia is described from the Parque Estadual das Sete Passagens, Bahia, Brazil. Microlicia roseopetala appears to be related to M. leucopetala, but differs by having smaller flowers with shorter hypanthia (1.8–2.6 mm long), shorter calyx lobes (2.0–2.7 mm long) that are oblong to triangular, shorter magenta petals (4.6–6.6 mm l...
Marcetia wilburiana is described and illustrated from the southwestern region of the Chapada Diamantina in Bahia, Brazil, where it appears to be a rare and local species of campo rupestre. Its affinities appear to be with M. ericoides and M. shepherdii, both of which have a wiry subshrubby habit; small, coriaceous, glabrous leaves that are appresse...
Three new species of the Neotropical genus Marcetia are described and illustrated: Marcetia barbadensis, Marcetia minima, and Marcetia serratifolia.

The recognition of Marcetia barbadensis and Marcetia serratifolia is confirmed with an...
Microlicia crenatifolia is described from the Diamantina Plateau, a well-known hotspot of plant endemism in southeastern Brazil. It can be recognized by its small leaves (up to 8.3 mm long) that are conspicuously crenulate to slightly serrate, short floral pedicels (0.7-1.0 mm long), and linear calyx lobes that are externally glandular-punctate and...

Microlicia is a Neotropical genus with about 245 species centered in central-eastern Brazil, in areas of campo rupestre and Cerrado. The majority of species occur in the states of Minas Gerais, Bahia, and Goiás. Based on specimens from the herbaria ALCB, HUEFS, MBM, SPF, HUFU, and US, we here describe two new species from the Chapada Diamantina reg...
Understanding how and why fish species composition varies between locations through beta‐diversity has received increased interest recently. The physical structure, extension and environmental characteristics along the river basins influence the dispersal of organisms, which ultimately affects metacommunity dynamics and biodiversity patterns. Here,...
The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

Brazilian biodiversity is undergoing numerous attacks and misguided policies that aim to reduce protected areas (PAs) with the main argument of expanding agribusiness to improve the country's economic performance. An example is the draft law (DL) 527/2016, which aimed to reduce approximately 70% of the Devonian Escarpment Environmental Protection A...
The Cadeia do Espinhaço (also referred to as “Espinhaço Range”) is a mountain range that extends for more than 1,200 km from northern Bahia to southern Minas Gerais in eastern Brazil. Mountains in the Cadeia do Espinhaço usually have impoverished soils and complex micro-habitats, where outstanding levels of endemism are found. Pleistocene glaciatio...
• The delimitation of conservation units may be supported by information on compositional (taxonomic), functional, and phylogenetic diversity of a given locality or region. In this context, systematic conservation planning and key biodiversity areas are promising approaches for biodiversity protection.
• Factors such as species representativeness a...
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...

Microlicieae is a Neotropical tribe of Melastomataceae, and most of its species are endemic to Brazil, especially in campo rupestre sites. The campo rupestre ecosystem occurs in areas with shallow soils deficient in water and nutrients, and elevations above 900 m. Foliar characters provide important structural features which are of taxonomic value...

The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...
