Family legacy: contrasting diversity–elevation relationships on a coastal Atlantic Forest mountain system
(Plant Ecology, 2022) [Artigo]Unveiling the ecological processes driving diversity and its relationship to the environment remains a central goal in ecological studies. Here, we investigated the elevation effect on plant beta-, phylogenetic and ... -
How candidate genes respond to aluminum toxicity in Citrus x limonia Osbeck?
(Theoretical and Experimental Plant Physiology, 2022) [Artigo]In acidic soils, toxic aluminum (Al) inhibits root growth of sensitive species, including Citrus plants. In the Americas, rainfed Citrus plantations are highly dependent on unique rootstocks, such as the ‘Mandarin’ lime ... -
Phenological patterns of herbaceous Mediterranean plant communities in spring: is there a difference between native and formerly-cultivated grasslands?
(Plant Ecology and Evolution, 2022) [Artigo]Background and aims – Plant phenology, defined as the timing of recurring life events like leaf flushing, flowering, or fruiting, is highly sensitive to environmental factors such as photoperiod, temperature, and moisture. ... -
Do aluminum (Al)-accumulating species from the Brazilian savanna accumulate Al in the roots?
(Trees - Structure and Function, 2022) [Artigo]Key message: Al-accumulating species are tolerant, accumulating more than 1000 mg Al kg−1 dry leaves, and varying root Al concentrations. Non-accumulating species are ‘avoiders’, retaining low root and leaf Al concentrations. ... -
Benefits of alignment quality-control processing steps and an Angiosperms353 phylogenomics pipeline applied to the Celastrales
(Cladistics, 2022) [Artigo]We examined the impact of successive alignment quality-control steps on downstream phylogenomic analyses. We applied a recently published phylogenomics pipeline that was developed for the Angiosperms353 target-sequence-capture ... -
Influence of palm trees on the richness and distribution of plant species on the murundus at a Caatinga/Cerrado ecotone
(Rodriguesia, 2022) [Artigo]Understand the role of the drivers in vegetation pattern is essential in ecology since diversity plays a major role in the stability and maintenance of plant communities. The murundus are small and scattered earthmounds ... -

Plants in the clouds: vascular epiphytes of Pedra Azul, a mountain top in Espírito Santo, Southeastern Brazil
(Rodriguesia, 2022) [Artigo]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?
(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
(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 ... -
Do neighbours matter? The effect of single- and mixed-species sowing density on seed germination of annual wetland plants
(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 ... -
Many roads to success: different combinations of life-history traits provide accurate germination timing in seasonally dry environments
(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 ... -
Plant communities in tropical ancient mountains: How are they spatially and evolutionary structured?
(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
(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?
(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
(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
(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
(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
(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 ... -
