A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

open access: yesNordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

open access: yesOikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

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

Trait‐associated pathway links plant diversity to litterfall phenology in a seasonally dry tropical forest

open access: yesOikos, EarlyView.
Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...
