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

open access: yesPapeis 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]

open access: yesEcol 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.

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]

open access: yesJ 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 ...

A missing piece is found: a new species of Paepalanthus (Poales, Eriocaulaceae) and the puzzling relations of the campos rupestres mountaintop floras of eastern Minas Gerais, Brazil [PDF]

open access: yesPhytoKeys
Paepalanthus is a diverse genus characteristic of the campos rupestres, a megadiverse vegetation found on mountaintops of mainly quartzitic mountain ranges of central-eastern Brazil. Recent efforts on prospecting the biodiversity of Serra do Padre Ângelo,

Lithobiomes Heterogeneity and Geographic Distance Shape the Landscape Genomics Within Brazilian Mountain Systems [PDF]

open access: yesEcology and Evolution
Lithological heterogeneity, climatic gradients, and geographic distance may shape the genetic structure of montane plant species, but their combined effects remain underexplored in Neotropical ecosystems.

O fogo é sempre um vilão nos campos rupestres?

open access: yesBiodiversidade Brasileira, 2011
Os campos rupestres ocupam menos de 3% das áreas de Cerrado e Caatinga, mas abrigam uma proporção significativa das espécies vegetais vasculares presentes nestes biomas.
