Do Aquatic Macrophytes Limit the Invasion Potential of Exotic Species in Pantanal Grasslands?
Bao, Francielli; ; de Assis, Marco Antonio ; ; (Wetlands, 2019) [Artigo]
Natural disturbances have the potential to limit exotic species invasions. The exotic grass, Urochloa humidicola, has high propagation potential following seasonal flooding, but, flooding tends to reduce the cover. Neither ... -

Aluminum-accumulating Vochysiaceae species growing on a calcareous soil in Brazil
Nogueira, Matheus Armelin; Bressan, Anna C. G. ; ; Habermann, Gustavo (Plant and Soil, 2019) [Artigo]
Aims: Cerrado woody species are divided into a small group of aluminum (Al)-accumulating species and the rest of the woody species. Both groups grow well on acidic and Al-rich soils. We found a Cerrado remnant growing on ... -
Seasonal dynamics of the water relations and photochemical efficiency of Copaifera langsdorffii Desf. co-occurring in savanna and seasonal forest

Seasonal dynamics can have important effects on vegetation structure and the physiological responses of species that co-occur in tropical savanna and seasonal forest. Few studies have revealed the physiological adjustments ... -
How flower colour signals allure bees and hummingbirds: a community-level test of the bee avoidance hypothesis
de Camargo, Maria Gabriela Gutierrez; ; ; ; ; Morellato, Leonor Patrícia Cerdeira (New Phytologist, 2019) [Artigo]
Colour signals are the main floral trait for plant–pollinator communication. Owing to visual specificities, flower visitors exert different selective pressures on flower colour signals of plant communities. Although they ... -
The diversity and evolution of pollination systems in large plant clades: Apocynaceae as a case study
; ; ; ; ; ; ; ; ; Amorim, Felipe W. et al. (Annals of Botany, 2019) [Artigo]
Background and Aims: Large clades of angiosperms are often characterized by diverse interactions with pollinators, but how these pollination systems are structured phylogenetically and biogeographically is still uncertain ... -
Fusoid cells in the grass family Poaceae (Poales): A developmental study reveals homologies and suggests new insights into their functional role in young leaves
Leandro, Thales D.; Rodrigues, Tatiane Maria ; ; Scatena, Vera Lucia (Annals of Botany, 2018) [Artigo]
Background and Aims In mature grass leaf blades as seen in cross-section, oblong cell-like structures have been interpreted most recently as intercellular gas spaces delimited by successive collapsed fusoid cells. These ... -
First record of Oziroë argentinensis (Lillo & Hauman) Speta (Asparagaceae) for Brazil
Melo, Pablo Hendrigo Alves de; Lombardi, Julio Antonio (Feddes Repertorium, 2019) [Artigo]
We report the first record of Oziroë argentinensis (Asparagaceae) for Brazil, previously known from Paraguay, Bolivia, and Argentina. The plant was collected in the state of Mato Grosso do Sul, growing between limestone ... -
Tropical mountains as natural laboratories to study global changes: A long-term ecological research project in a megadiverse biodiversity hotspot
; ; ; ; ; Morellato, Leonor Patrícia Cerdeira; ; ; ; (Perspectives in Plant Ecology, Evolution and Systematics, 2019) [Resenha]
Campo rupestre is a megadiverse vegetation mosaic dominating one of the world's geologically oldest tropical mountains. The campo rupestre hosts nearly 15% of Brazil's flora, with 40% of endemism in an area smaller than ... -
Decarboxylation mechanisms of C4 photosynthesis in Saccharum spp.: Increased PEPCK activity under water-limiting conditions
; ; ; ; Domingues, Douglas Silva; ; (BMC Plant Biology, 2019) [Artigo]
Background: C4 plants have been classified into three subtypes based on the enzymes used to decarboxylate C4 acids in the bundle sheath cells (NADP-ME, NAD-ME and PEPCK pathways). Evidences indicate that, depending on ... -
Towards a phylogenetic classification of the Ocotea complex (Lauraceae): classification principles and reinstatement of Mespilodaphne
; De Moraes, Pedro L. R.; (Botanical Journal Of The Linnean Society, 2019) [Artigo]
The large genus Ocotea (c. 400 species) has been known to be paraphyletic with respect to most other Neotropical genera of Lauraceae for almost 20 years, but a phylogenetic classification has not yet been proposed. Here ... -
Seed Morphology of Ruellieae Species (Acanthaceae) in Brazil and Its Taxonomic Implications
Freitas Azevedo, Igor Henrique; Rodrigues de Moraes, Pedro Luis (Systematic Botany, 2019) [Artigo]
