Cloud forests usually occur at high-altitude sites of the Atlantic Forest in eastern Brazil, albeit scattered and fragmented along the mountain tops. In this habitat, the vegetation occurs at low-temperature conditions and ... -
Is aluminum (Al) eliminated by senescent structures of Miconia albicans, an Al-accumulating species from Brazilian savanna?
Timpone, Luá Taibo; Habermann, Gustavo (Flora: Morphology, Distribution, Functional Ecology of Plants, 2022) [Artigo]
Aluminum (Al)-accumulating plants are distributed worldwide. In the Cerrado vegetation in South America, these plants occur as few woody species from Melastomataceae, Rubiaceae, Syplocaceae and Vochysiaceae. Nevertheless, ... -
Phenology of Zamia boliviana (Zamiaceae), a threatened species from a seasonally dry biodiversity hotspot in South America
Segalla, Rosane; ; ; Morellato, Leonor Patrícia Cerdeira (Plant Species Biology, 2022) [Artigo]
Dioecy, a character common to all cycads, requires obligatory outcrossing. The absence of potential reproductive mates of the opposite sex renders individuals effectively sterile. Therefore, reproductive synchrony is ... -
Many roads to success: different combinations of life-history traits provide accurate germination timing in seasonally dry environments
Escobar, Diego Fernando Escobar; ; Morellato, Leonor Patricia Cerdeira (Oikos, 2021) [Artigo]
Germination timing is determined by several plant life-history traits. Seed dormancy regulates the time and place of early plant development and spreads recruitment risks over time. Dispersal phenology and syndrome can ... -
Do neighbours matter? The effect of single- and mixed-species sowing density on seed germination of annual wetland plants
Bao, Francielli; Rossatto, Davi Rodrigo ; ; ; de Assis, Marco Antonio ; ; Ramos, Desirée Marques (Applied Vegetation Science, 2021) [Artigo]
Question: Germination is one of the decisive processes influencing species presence and plant community structure. Here, we investigated the influence of seed density and single and mixed species on germination percentage ... -
Plant communities in tropical ancient mountains: How are they spatially and evolutionary structured?
; Morellato, Leonor Patrícia C.; (Botanical Journal of the Linnean Society, 2021) [Artigo]
The integration of phylogenetic methods and species distribution can really help in the investigation of biogeographic patterns and to fill gaps in evolutionary ecology. Here we investigated how the vascular flora of the ... -
Temporal organization among pollination systems in a tropical seasonal forest
Genini, Julieta; ; ; ; Morellato, Leonor Patrícia Cerdeira (Science of Nature, 2021) [Artigo]
Temporal constancy of pollination systems is essential for the maintenance of pollinators through time. Community-level assessment of flowering phenology allows understanding variations across seasons and years and the ... -
Could the absence of aluminum (Al) impair the development of an Al-accumulating woody species from Brazilian savanna?
Bressan, Anna Carolina Gressler; de Oliveira Carvalho Bittencourt, Brenda Mistral ; Silva, Giselle Schwab ; Habermann, Gustavo (Theoretical and Experimental Plant Physiology, 2021) [Artigo]
Vochysia tucanorum (Vochysiaceae) is an aluminum (Al)-accumulating tree species from the Cerrado vegetation in South America, known as ‘Brazilian savanna’. In the field, it may accumulate up to 20,000 mg Al kg−1 dry leaf ... -
Leaf venation of Ocotea species (Lauraceae) from Bahia, Brazil
Moraes, Pedro Luís Rodrigues de; Ribeiro, Henrique Lauand ; Coan, Alessandra Ike ; (Feddes Repertorium, 2021) [Artigo]
With the aim of recognizing and identifying both fertile and sterile specimens of Ocotea from the Brazilian state of Bahia, we analyzed the leaf venation pattern of 55 species, 21 of them being described and illustrated ... -
Applicability of seed bank assessment methods in wetlands: Advantages and disadvantages
Bao, Francielli; de Assis, Marco Antonio ; (Oecologia Australis, 2021) [Artigo]
The soil seed bank is the primary source of regeneration in wetlands and has different assessment methods that vary according to the objective of the study. We evaluated the seed bank composition using three methods: ... -
Leaf venation of Ocotea species (Lauraceae) from the Reserva Natural Vale, Linhares, Espírito Santo, Brazil
Moraes, Pedro Luís Rodrigues de; Cruz, Isabel Cristina Lima da ; Coan, Alessandra Ike ; (Feddes Repertorium, 2021) [Artigo]
With the aim of recognizing and identifying both fertile and sterile specimens of Ocotea from the Reserva Natural Vale, Linhares, we analyzed the leaf venation pattern of 31 species, 13 of them being described and illustrated ... -
Secondary metabolites produced by endophytic fungi: Novel antifungal activity of fumiquinone B
; Correia, Ana Maria Lima; ; Rodrigues, Andre ; Assis, Marco Antonio ; ; ; (Acta Scientiarum - Biological Sciences, 2019) [Artigo]
Fungi are present in the most diverse environments including the interior of plant tissues, living as endophytes without causing apparent damage. These endophytes are producers of secondary metabolites, also known as natural ... -
Pixelwise Time Series Retrieval in Phenological Studies
; Alberton, Bruna; Morellato, Leonor Patricia ; (International Geoscience and Remote Sensing Symposium (IGARSS), 2019) [Trabalho apresentado em evento]
The support of time series similarity searches might be crucial in phenology studies, in which long-term time series analysis based on the identification of similar and different phenological patterns shared by individuals ... -
Topography and seasonality promotes taxonomic beta diversity of seedlings in a tropical wetland
Bao, Francielli; ; ; ; de Assis, Marco Antonio ; ; (Oecologia Australis, 2019) [Artigo]
Spatial and temporal beta diversity of seedlings in tropical wetland remain poorly understood. We assessed the ecological pattern of taxonomic beta diversity of seedling assemblages along a topographic gradient, seasonally ... -
