30 Years of postdisturbance recruitment in a Neotropical forest. [PDF]
Ecol Evol, 2021 We examined recruited trees taxonomic/functional diversity/composition trajectories in a Neotropical forest to identify the processes underlying community response to a disturbance gradient. We revealed a two‐phase successional pathway defined by (a) the emergence of deterministic recruitment processes enhancing the recruitment of light‐demanding ...

The mutualism-antagonism continuum in Neotropical palm-frugivore interactions: from interaction outcomes to ecosystem dynamics. [PDF]
Biol Rev Camb Philos Soc, 2022 ABSTRACT Frugivory, that is feeding on fruits, pulp or seeds by animals, is usually considered a mutualism when interactions involve seed dispersal, and an antagonism when it results in the predation and destruction of seeds. Nevertheless, most frugivory interactions involve both benefits and disadvantages for plants, and the net interaction outcomes ...

Insights From a New 1-ha Permanent Forest Plot Reveal Differences Between Habitat Type and Similarities Between Forest Type in the Southwestern Amazon. [PDF]
Ecol EvolSouthwestern Amazon forests are highly diverse, but information on how tree diversity and composition changes between habitat and forest types remains scarce. We conducted floristic analyses to investigate these changes across a precipitation gradient, between habitat types, and between disturbed and old‐growth forest.

Relieving efforts in palm-tree tissue sampling for population genetics analyses. [PDF]
Ecol Evol, 2021 This study tests root tissue viability as an alternative nucleic acid source (root vs. leaf) and explores different protocols (tissue storage and DNA purification methods) to obtain high‐quality DNA samples. Results showed the effective potential of using root tissue as an alternative source, which could facilitate populations sampling of palm‐tree ...

Capacidad antioxidante del néctar de ungurahuí (Oenocarpus bataua)
Nutrición Clínica y Dietética Hospitalaria, 2022 ABSTRACT Introduction: Studies of antioxidant capacity in fruit drinks are related to the content of polyphenols, carotenoids and flavonoids. Objective: To evaluate the antioxidant capacity of the nectar of ungurahuí (Oenocarpus bataua) in the process of making the nectar, in the stages of selection, pre-cooking, standardization and nectar, and the ...

Genotyping-by-sequencing informs conservation of Andean palms sources of non-timber forest products. [PDF]
Evol ApplAbstract Conservation and sustainable management of lineages providing non‐timber forest products are imperative under the current global biodiversity loss. Most non‐timber forest species, however, lack genomic studies that characterize their intraspecific variation and evolutionary history, which inform species' conservation practices.

Taxonomy of the Oenocarpus-Jessenia (Palmae) complex in Brazil [PDF]
Acta Amazonica, 1985 Two genera, Oenocarpus and Jessenia are recognized in this complex of Neotropical palms. They are well represented in Brasil, Oenocarpus with seven species (O. distinchus, O. discolar, O. tarampabo, O. bacaba, O. macrocalyx, O. mapora and O.

Degree of seed desiccation sensitivity of the Amazonian palm Oenocarpus bacaba depends on the criterion for germination [PDF]
Acta Amazonica, 2021 Across the seed-seedling transition, several germination criteria are used in studies of palm-seed germination. In Oenocarpus bataua, these criteria have differential tolerance to thermal stress.
