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

Oikos, 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

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Floristic survey of Rubiaceae in the largest remnant of Cerrado in the metropolitan region of São Paulo, Brazil

Rodriguésia
We present a floristic survey of the family Rubiaceae in Juquery State Park, a conservation unit that harbors the largest Cerrado area in the metropolitan region of São Paulo and is a refuge within the Atlantic Forest domain. The work was conducted using

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

Oikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Towards integrative taxonomy in Neotropical botany: Disentangling the Pagamea guianensis species complex (Rubiaceae) [PDF]

, 2018
Species complexes are common in the Neotropical flora, and the Pagamea guianensis complex is one of the most widespread groups of species in the Amazonian white-sand flora.

Multifaceted obscurity of Thismia abei (Thismiaceae): A fairy lantern with the protologue long disregarded in practice

PLANTS, PEOPLE, PLANET, EarlyView.
Tiny, leafless fairy lanterns are easily overlooked on the forest floor. Thismia abei, endemic to Japan, persists in small, unstable populations and is listed nationally as Critically Endangered. Our recent work has revealed another, less obvious form of obscurity.

The Origin and Diversification of the Hyperdiverse Flora in the Chocó Biogeographic Region

Frontiers in Plant Science, 2019
Extremely high levels of plant diversity in the American tropics are derived from multiple interactions between biotic and abiotic factors. Previous studies have focused on macro-evolutionary dynamics of the Tropical Andes, Amazonia, and Brazil’s Cerrado
