Host specificity and aggregation for a widespread mistletoe in Campo Rupestre vegetation [PDF]
Assessment of host infection and distribution patterns are crucial to understand the underling mechanisms that shape parasitic plant spread in natural ecosystems. However, such data remain scarce for mistletoes inhabiting Brazilian campo rupestre vegetation, old-growth montane fire-prone grasslands. We evaluated the host range and distribution patterns

Two new Critically Endangered species of Ditassa (Apocynaceae) from the threatened cangas of the Iron Quadrangle, Minas Gerais, Brazil [PDF]
Background and aims – Vegetation on ironstone outcrops is highly threatened, particularly due to the impact of mining. In this study, two new species of Ditassa (Metastelmatinae, Asclepiadoideae, Apocynaceae) from the cangas of the Iron Quadrangle (Minas

Systematics and cryptic diversification of Leptodactylus frogs in the Brazilian campo rupestre
AbstractThe campo rupestre is a unique mountaintop ecosystem in eastern South America, recognised for its endemism and as ecological refugia for plant and animal taxa. Multiple clades of frogs are represented in the Brazilian campo rupestre. One such case is four species of the Leptodactylus fuscus group, three of which are endemic to specific mountain

Environmental severity promotes phylogenetic clustering in campo rupestre vegetation [PDF]
The stress-dominance hypothesis postulates that the importance of competition in plant communities declines with increasing environmental stress while the importance of environmental filters increases. To test this hypothesis for campo rupestre vegetation, we analyzed phylogenetic diversity and community structure of angiosperm communities at two study

Lack of floristic identity in campos rupestres − a hyperdiverse mosaic of rocky montane savannas in South America [PDF]
The rocky montane savannas of South America, known as campos rupestres in Brazil, where they largely occur, represent a megadiverse habitat housing c.15% of the Brazilian vascular flora in less than 1% of the Brazilian territory.

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