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

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 ...

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 ...

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.

Microbiomes of Velloziaceae from phosphorus-impoverished soils of the campos rupestres, a biodiversity hotspot. [PDF]

Sci Data, 2019
AbstractThe rocky, seasonally-dry and nutrient-impoverished soils of the Brazilian campos rupestres impose severe growth-limiting conditions on plants. Species of a dominant plant family, Velloziaceae, are highly specialized to low-nutrient conditions and seasonal water availability of this environment, where phosphorus (P) is the key limiting nutrient.

Patterns of geographic distribution and conservation of the open-habitat avifauna of southeastern Brazilian mountaintops (campos rupestres and campos de altitude)

Papeis Avulsos De Zoologia, 2010
Montane open-habitats of southeastern Brazil are represented by the campos rupestres (principally in the Espinhaço Range) and by the campos de altitude (in the Serra do Mar and Serra da Mantiqueira).

Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]

Ecol Evol
Climate change is projected to sharply reduce suitable habitats for eight endemic rupestrian plant species in Brazil's Iron Quadrangle. Ensemble niche models reveal species‐specific vulnerabilities and highlight climatic refugia and corridors that may support persistence.

Seasonal bacterial profiles of Vellozia with distinct drought adaptations in the megadiverse campos rupestres. [PDF]

Sci Data
Microbial communities can vary as a function of seasonal precipitation and the phenotypic characteristics of the prevailing plant species in an ecosystem. The Brazilian campos rupestres (CRs) host a unique flora adapted to harsh conditions, including severe droughts and nutrient-poor soils.

Plotting a future for Amazonian canga vegetation in a campo rupestre context. [PDF]

PLoS One, 2019
In order to establish effective conservation strategy, drivers of local and regional patterns of biodiversity need to be understood. The composition of local biodiversity is dependent on a number of factors including evolution and redistribution of lineages through dispersal and environmental heterogeneity.

Testing the Limits of Morphology: A Comprehensive Morphometric Study of the Sister Lineages Lasiocyano Galleti-Lima, Hamilton, Borges and Guadanucci, 2023 and Lasiodora C. L. Koch, 1850 (Theraphosidae, Mygalomorphae). [PDF]

J Morphol
An extensive morphometric framework combining linear and geometric morphometry was applied to evaluate interspecific differentiation within the Lasiocyano sazimai and Lasiodora lineage (Theraphosidae). Despite statistically significant differences in some analyses, extensive morphological overlap and high intraspecific variation consistently reduced ...
