Regeneration after fire in campo rupestre: Short- and long-term vegetation dynamics [PDF]

Flora, 2018
The Cerrado (Brazilian savanna) is the second largest biome in Brazil, covering 22% of the country, and campo rupestre is one of the most biodiverse ecosystem. Campo rupestre are extremely old mountaintop tropical ecosystems, composed of a mosaic of herbaceous, shrubland and savanna vegetation, generally located above 900 m above sea level ...

Ants in Burned and Unburned Areas in Campos Rupestres Ecosystem

Sociobiology, 2016
Ground-dwelling ants have shown consistent resilience to fire in savanna environments. We carried out a study to investigate how ant community structure responds to fire in a harsh and fragile Cerrado ecosystem, the campos rupestres. We studied the change in the ant communities on a local scale subjected to fire in two rocky outcrop habitats at two ...

Determinant factors for epiphyte-phorophyte interactions in patches of cloud forest within a matrix of campos rupestres [PDF]

Acta Botânica Brasílica
The epiphytic flora is influenced by the architecture and morpho-physiology of phorophytes. Our knowledge about the ecology of these communities remains limited, especially in the campos rupestres.

Testing arbitrary classes of light in a physiognomically heterogeneous area of "campo rupestre" vegetation [PDF]

Anais da Academia Brasileira de Ciências, 2013
The Brazilian "campo rupestre" vegetation shows high light heterogeneity, characteristic which is often disregarded in ecophysiological studies due the difficult of obtaining accurate measurements in a complex environment. The aim of the present study it was to describe how much heterogeneous is the light distribution in this environment, as well as ...

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Beyond forests: Harnessing conservation gardening for open biomes in Brazil

PLANTS, PEOPLE, PLANET, EarlyView.
Urban gardening offers an innovative conservation strategy by integrating native ornamental species into urban landscapes. We evaluated the ornamental potential of the Brazilian flora by comparing the representation of species from forests versus open biomes (focusing on campo rupestre grasslands) and introduced and validated the Index of Ornamental ...

Plant life in campo rupestre : New lessons from an ancient biodiversity hotspot [PDF]

Flora, 2018
The years 2011–2020 represent the United Nations Decade of Biodiversity, aiming to inspire worldwide actions to support biodiversity conservation. This Special Issue illustrates the current knowledge of plant life in campo rupestre, a megadiverse, highly-endemic vegetation complex, and one under alarming and unprecedented threats.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

The Global South's OCBIL Theory Helps Elucidate Evolution, Ecology, and Conservation in Biological and Cultural Diversity

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Ecological theory has been shaped disproportionately by studies conducted in young, disturbance‐prone, relatively fertile landscapes (YODFELs), mostly in the Global North. Yet, many megadiverse regions in the Global South are dominated by old, climatically buffered, infertile landscapes (OCBILs), resulting in fundamentally different patterns that ...
