Vitex oreadica and V. umbellata (Lamiaceae): two new species from Cerrado and Atlantic forest of Brazil

open access: yesNordic 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.

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

open access: yesOikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...
