Family legacy: contrasting diversity–elevation relationships on a coastal Atlantic Forest mountain system
de Andrade Kamimura, Vitor
; Marcusso, Gabriel Mendes ; Sabino, Gabriel Pavan ; Assis, Marco Antonio ; ; de Paula Loiola, Priscilla (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?
Silva, Carolina M. S.; ; Domingues, Douglas S. ; Habermann, Gustavo (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?
; ; Morellato, Leonor Patricia C.; (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?
Zaia, Marina; Timpone, Luá Taibo ; Habermann, Gustavo (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
; ; ; ; ; Lombardi, Julio A.; ; (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
; ; ; ; ; Marcusso, Gabriel Mendes; (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
Marcusso, Gabriel Mendes; ; Lombardi, Julio Antonio (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?
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 ... -
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 ... -
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 ... -
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 ... -
