Nordic Journal of Botany, EarlyView.Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

Rare frost events reinforce tropical savanna–forest boundaries
Journal of Ecology, 2018 The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be important for maintaining savanna,

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)
Nordic Journal of Botany, EarlyView.Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

International Savanna Fire Management Initiative
Biodiversidade Brasileira, 2019 Due to colonisation, traditional ways of fire management have been suppressed across landscapes and as a result vast areas of country are poorly managed and degraded. Conventional methods of firefighting have largely failed. Climate change will make the

Frontiers in Plant Science, 2018 The evolutionary processes underlying the high diversity and endemism in the Cerrado, the most extensive Neotropical savanna, remain unclear, including the factors promoting the presence and evolution of savanna enclaves in the Amazon forest.

Nutrients in an African Savanna: the consequences of supply heterogeneity for plants and animals
, 2010 In savannas, trees and grasses co-exist and share resources such as water and nutrients. The ratio between the tree and grass components (i.e., vegetation structure) importantly controls productivity, animal assemblages and earth-atmosphere feedbacks.

Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas
Nordic Journal of Botany, EarlyView.We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to
