The mutualism–antagonism continuum in Neotropical palm–frugivore interactions: from interaction outcomes to ecosystem dynamics

C Marques Dracxler, WD Kissling - Biological Reviews, 2022 - Wiley Online Library
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 …

Variation in fruit and seed dimensions is better explained by dispersal system than by leaf size in a tropical rainforest

PR Stevenson, DC Acosta‐Rojas… - American Journal of …, 2023 - Wiley Online Library
Premise Variation in fruit and seed traits could originate from selection pressures exerted by
frugivores or other ecological factors (adaptive hypotheses) and developmental constraints …

Oilbirds disperse large seeds at longer distance than extinct megafauna

PR Stevenson, L Cardona, S Cárdenas, A Link - Scientific Reports, 2021 - nature.com
The extinction of megafauna in the Neotropics is thought to have reduced the potential of
large seeds to be dispersed over long distances by endozoochory (ingestion by animals) …

Are seeds able to germinate before fruit color ripening? Evidence from six Neotropical bird‐dispersed plant species

DM Cruz‐Tejada, DC Acosta‐Rojas… - Ecosphere, 2018 - Wiley Online Library
Many plants attract seed dispersers and indicate the presence of ripe, fleshy fruits with
coloration changes. If seed maturation is simultaneous with visual signs for frugivorous, a …

Subannual phenology and the effect of staggered fruit ripening on dispersal competition

SC Schubert, EL Walters - Biotropica, 2022 - Wiley Online Library
Seed dispersal mutualisms evolve in complex communities of plants and frugivorous
animals, within which indirect interactions such as competition and facilitation can occur …

Seed dispersal effectiveness by oilbirds (Steatornis caripensis) in the Southern Andes of Colombia

S Cárdenas, MÁ Echeverry‐Galvis, PR Stevenson - Biotropica, 2021 - Wiley Online Library
Oilbirds are specialized frugivores that disperse seeds; however, no study has evaluated
their seed dispersal effectiveness (SDE). We estimated SDE for nine plant species and …
