The deadly route to collapse and the uncertain fate of Brazilian rupestrian grasslands [PDF]

open access: yesBiodiversity and Conservation, 2018
Rupestrian grasslands are biodiverse, evolutionary old vegetation complexes that harbor more than 5000 species of vascular plants and one of the highest levels of plant endemism in the world. Growing on nutrient–impoverished soils and under harsh environmental conditions, these mountaintop ecosystems were once spared from major human interventions of ...

Vellozioid roots allow for habitat specialization among rock‐ and soil‐dwelling Velloziaceae in campos rupestres

open access: yesFunctional Ecology, Volume 34, Issue 2, Page 442-457, February 2020., 2020
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Plant growth on harsh substrates (habitat specialization) requires specific traits to cope with stressful conditions. We tested whether traits related to nutrient acquisition (root colonization by fungal symbionts, and plant morphological and ...
