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

Ecology 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.

A New Species of Calycolpus (Myrtaceae) from the Campos Rupestres, Minas Gerais, Brazil

Novon, 1998
Calycolpus australis (Myrtaceae) of Minas Gerais, Brazil, is described as a new species. It is perhaps most similar to C. alternifolius but differs in various floral characters. This new species extends the range of the genus six degrees of lati- tude farther south. Calycolpus is a genus of ca. 10 species ranging from Central America to Brazil with the

Floristic mosaics of the threatened Brazilian campo rupestre

Nature Conservation Research, 2022
The increase in rates of habitat loss requires an understanding of how biodiversity is distributed. Campo rupestre is an old, climatically buffered, and infertile landscape located in Brazil. Considered a biodiversity hotspot, the campo rupestre is mainly threatened by mining activity that requires a large operating area.

EXTENDING THE LIMITS OF CAMPOS RUPESTRES IN BRAZIL

Caminhos de Geografia, 2021
Campos rupestres are typical ecosystems of rock outcrops with high biodiversity and endemism, located in Brazilian territory, with vegetation analogous in Africa and Australia. The campos rupestres cover deeply dystrophic soils on highlands inserted in Amazon rainforest, Atlantic rainforest and Cerrado biomes. Despite recognition of campos rupestres as
