Biodiversity and ecosystem services in the Campo Rupestre: A road map for the sustainability of the hottest Brazilian biodiversity hotspot [PDF]

Perspectives in Ecology and Conservation, 2020
Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. The undeniable importance of conserving tropical forests has drawn most

An assessment of methods to combine evolutionary history and conservation: A case study in the Brazilian campo rupestre [PDF]

Applications in Plant Sciences
Premise Conservation policies typically focus on biodiversity hotspots. An alternative approach involves analyzing the evolutionary history of lineages in geographic areas along with their threat levels to guide conservation efforts.

Germination niche of campo rupestre plants: effects of increased temperature and darkness

Journal of Mountain Science
Anthropogenic disturbances are causing significant impacts on plant distribution worldwide, and many of these effects are driven by changes in the recruitment patterns of plant species.

Two new species of Microlicia (Melastomataceae) from unprotected campo rupestre in the western Chapada Diamantina, Bahia, Brazil [PDF]

PhytoKeys
Microlicia D.Don (Melastomataceae, Lavoisiereae) is a genus of shrubs and subshrubs comprising nearly 300 species, primarily distributed across nutrient-poor, open habitats in Brazil’s campos rupestres, cerrado, and other montane ecosystems.

Forest islands sustain more temporally stable insect metacommunities in a heterogeneous tropical mountaintop landscape [PDF]

npj Biodiversity
We evaluated how habitat type influences community temporal dynamics in a heterogeneous tropical mountain landscape. We sampled ants, dung beetles, and fruit-feeding butterflies across two mountaintop habitats: campo rupestre and forest islands in the ...

Microclimate drives demographic compensation in a narrow endemic tropical species. [PDF]

New Phytol
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]

Ecol 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.
