Introduction
I have been studying plant diversity for 10 years, with a particular focus on understanding bromeliad diversity in Brazil and adjacent regions. My research focuses on taxonomy and systematics, and incorporates field work and natural history collections with computational approaches.

Article
Full-text available
The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impedime...
Article
Vriesea psittacina is a widespread bromeliad species in the Brazilian Atlantic Forest. Here, we discuss nomenclatural issues of its infraspecific classification. We performed a nomenclatural revision based on the main monographs for the family Bromeliaceae. In addition, we analyzed specimens to clarify questions involving the associated binomials 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...
Article
Full-text available
Bromeliaceae arose in the Early Cretaceous, diverging from Typhaceae at ca. 125 Ma. After an apparent evolutionary stasis of 100 million years, they have undergone a high diversification starting in the Miocene. By adding fossils to the phylogenies, one can infer dates of arising and the divergence of lineages and link them to geological and climat...
Article
Barbacenia rogieri (Velloziaceae), a disjunct species rare in herbaria, is redescribed from its natural habitat in Rio de Janeiro and Esp ırito Santo, Brazil. B. purpurea and B. rogieri are lectotypified; an epitype and a synonym are designated for the latter. Taxonomic and conservation status comments are provided along with the first color photos...

Livros didáticos (LDs) são instrumentos imprescindíveis e potencialmente determinantes no aprendizado. Aqui, visamos avaliar parâmetros de qualidade nos livros didáticos quanto à organografia vegetal. LDs de instituições que oferecem curso de Ensino Médio no estado do Rio de Janeiro foram escolhidos e analisados quanto à moda e mediana em conformid...
Article
Full-text available
Pollinators are important drivers of angiosperm diversification at both micro- and macroevolutionary scales. Both hummingbirds and bats pollinate the species-rich and morphologically diverse genus Vriesea across its distribution in the Brazilian Atlantic Forest. Here, we (i) determine if floral traits predict functional groups of pollinators as doc...
Article
Vriesea mimosoensis is described and illustrated as a new taxon from the Atlantic Forest in Espírito Santo, Southeastern Brazil. Morphological comparisons of this taxon with related species are presented. Here we discuss taxonomy comments, etymology, geographical distribution and the conservation status of this new species.
Article
Full-text available
Aim: Understanding the complex interaction and relative contributions of factors involved in species and trait diversification is crucial to gain insights into the evolution of Neotropical biodiversity. Here, we investigated the drivers of morphological variation in bromeliads along a latitudinal gradient in a biodiversity hotspot. Location: Atl...
Article
Full-text available
Subtribe Vrieseinae comprise four genera, Alcantarea, Stigmatodon, Vriesea s.s. and Waltillia, encompassing c. 20% of species in Tillandsioideae (Bromeliaceae), almost all of which are exclusive to Brazil. Here, we explore the biogeographic history of Vrieseinae, sampling 21 of the 22 genera of Tillandsioideae (130 terminals) and three DNA sequence...

Resumo O Parque Nacional da Serra dos Órgãos (PARNASO) localiza-se na região serrana do estado do Rio de Janeiro e representa uma importante unidade de conservação brasileira, guardando importantes ecossistemas da Mata Atlântica do sudeste do Brasil. Apresenta-se um estudo florístico-taxonômico dos gêneros Edmundoa, Neoregelia e Wittrockia (Bromeli...
Article
Full-text available
Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vas...

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...
Article
A new, critically endangered taxon, Vriesea mourae, endemic to the Serra da Bocaina mountains in southeastern Brazil, is described. We provide data on its conservation status, etymological and taxonomic notes, photographs, and illustrations. The taxon is morphologically similar to V. warmingii, differing mainly in the shorter blade, diameter of ped...
Article
In the eighteenth century, José Mariano da Conceição Vellozo in his work Flora Fluminensis, sought to expand the floristic knowledge of Rio de Janeiro and surroundings. This was the first flora of Brazil written and edited by a native naturalist. However, the existence and location of the type material of species described in this work are not know...

Full-text available
Vriesea Lindl. (Bromeliaceae) has its center of diversity in eastern Brazil, especially in the Atlantic Rainforest domain. The present study extended the distribution of V. agostiniana to São Paulo state and V. saltensis to Espírito Santo state; they were previously considered endemic to single locations in the states of Rio de Janeiro and Minas Ge...
Article
Full-text available
The infraspecific taxon Vriesea gradata Mez var. bicolor E. Pereira & I. A. Penna is elevated to the rank of species and given the new name V. fluviatilis Kessous & A. F. Costa, and the taxonomy and geographical distribution of this species are discussed.

Parque Nacional da Serra dos Órgãos is located between the cities of Teresópolis, Petrópolis, Guapimirim and Magé including from Low Montane Rainforest to High Altitude Fields. Bromeliaceae has about 3.503 species distributed in 59 genera. Canistropsis and Nidularium are endemic of Brazil and have their diversity center in the Atlantic Forest Domai...
