Angiosperm disjunction "Campos rupestres - restingas": a re-evaluation Disjunção de Angiospermas Campos Rupestres - Restingas: uma reavaliação [PDF]

Acta Botânica Brasílica, 2007
A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands) in the Espinhaço mountain range and the restingas (coastal strand vegetation) in Brazil has been proposed repeatedly for several flowering-plant ...

Exploring the mycobiota of bromeliads phytotelmata in Brazilian Campos Rupestres. [PDF]

Braz J Microbiol, 2023
The phytotelmata is a water-filled tank on a terrestrial plant, and it plays an important role in bromeliad growth and ecosystem functioning. Even though previous studies have contributed to elucidate the composition of the prokaryotic component of this aquatic ecosystem, its mycobiota (fungal community) is still poorly known. In the present work, ITS2

Habitat heterogeneity and diversity of bryophytes in campos rupestres [PDF]

Acta Botânica Brasílica, 2017
Campos rupestres (rupestrian grasslands) are characterized by the presence of rock outcrops associated with an herbaceous-shrub physiognomy typically growing on quartzitic soils; they occur a wide variety of habitats.

Plant Biodiversity Drivers in Brazilian Campos Rupestres: Insights from Phylogenetic Structure. [PDF]

Front Plant Sci, 2017
Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring ...

Modeling Climate Change Impacts on a Socioeconomically Vital Plant: The Case of <i>Comanthera elegans</i> (Goldenfoot Flower). [PDF]

Ecol Evol
Comanthera elegans, an ecologically important species in rocky grasslands, is projected to face significant habitat loss under future climate change scenarios. Modeling with the Maxent algorithm showed that its suitable habitats, defined by high rainfall seasonality and moderate temperatures, are at risk, especially under high greenhouse gas emissions.

Fine-tuning the buzz: comparing visitation frequency and pollination effectiveness in plant-pollinator networks. [PDF]

New Phytol
Summary Ecological network approaches have advanced our understanding of how species interactions influence community and evolutionary dynamics. However, a key limitation is that most network analyses rely solely on visitation data, often overlooking functional aspects of interactions.
