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

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Circumscribing campo rupestre – megadiverse Brazilian rocky montane savanas [PDF]

Brazilian Journal of Biology, 2014
Currently campo rupestre (CR) is a name accepted and used internationally by botanists, zoologists, and other naturalists, usually applied to a very specific ecosystem, despite the lack of a consensual published circumscription. We present a tentative geographic circumscription of the term, combining data on climate, geology, geomorphology, soil, flora,

ESPECTROS BIOLÓGICOS FLORÍSTICOS DE CAMPOS RUPESTRES DE AFLORAMENTO E CAMPOS ÚMIDOS DIFEREM ENTRE SI E EM RELAÇÃO AO ESPECTRO BIOLÓGICO NORMAL DE RAUNKIAER

Revista do Instituto Florestal, 2012
A distribuição de frequência de classes de formas de vida em uma flora, conhecida como espectro biológico florístico, varia em função das condições climáticas e edáficas em que as plantas se desenvolvem. Neste trabalho comparamos os espectros biológicos

CARACTERIZAÇÃO FLORÍSTICA DA VEGETAÇÃO SOBRE AFLORAMENTO ROCHOSO NA ESTAÇÃO EXPERIMENTAL DE ITAPEVA, SP, E COMPARAÇÃO COM ÁREAS DE CAMPOS RUPESTRES E DE ALTITUDE

Revista do Instituto Florestal, 2011
A classificação de comunidades vegetais nem sempre é tarefa fácil, principalmente quando se trata de tipos de vegetação pouco estudados. Esse é o caso da vegetação sobre afloramento rochoso da Estação Experimental de Itapeva – EEI, situada no sudoeste ...

Dissecting a biodiversity hotspot: the importance of environmentally marginal habitats in the Atlantic Forest Domain of South America [PDF]

, 2017
Aim We aimed to assess the contribution of marginal habitats to the tree species richness of the Mata Atlântica (Atlantic Forest) biodiversity hotspot. In addition, we aimed to determine which environmental factors drive the occurrence and distribution ...

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

Papéis 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).

Lychnophora pinaster in endangered campos rupestres: phenolic compounds and population ecogeography

Anais da Academia Brasileira de Ciências, 2023
Lychnophora pinaster, known as arnica-mineira, is endemic to campos rupestres, at risk of extinction. The present study aimed to characterize the ecogeography and phenolic constituents of 11 L. pinaster populations collected in the mesoregions North, Jequitinhonha, Metropolitan of Belo Horizonte and Campos das Vertentes in the state of Minas Gerais ...
