Inequalities in fruit-removal and seed dispersal: consequences of bird behaviour, neighbourhood density and landscape aggregation
TLDR
The authors' model and field data show an interaction between plant spatial pattern and bird foraging, which results in neighbourhood-specific dispersal and rates of fruit removal, and as fruiting plants become aggregated, inequalities in fruit-removal rates increase and seed dispersal distance decreases.

Crop Size and Fruit Neighborhood Effects on Bird Visitation to Fruiting Schefflera morototoni Trees in Puerto Rico
TLDR
The results highlight the important effects of local fruiting environments on the ability of individual plants to attract seed dispersers and the relative roles of crop size and fruit neighborhood variables in affecting visitation to focal trees by avian frugivores. Expand
Fruit quantity of invasive shrubs predicts the abundance of common native avian frugivores in central Pennsylvania
TLDR
Since populations of key bird frugivores may be currently depending on Lonicera resources, it is argued that control measures should account for the negative effects that the loss of this fruit resource could have on populations of native consumers in highly invaded regions. Expand
A new method to track seed dispersal and recruitment using 15N isotope enrichment.
TLDR
Stable isotope enrichment, combined with batch-sampling, is a cheap, reliable, and user-friendly method for bulk-processing seeds and is thus excellent for the detection of rare dispersal events. Expand
INTERSPECIFIC NEIGHBORS CHANGE SEED DISPERSAL PATTERN OF AN AVIAN-DISPERSED PLANT
TLDR
This work experimentally tested the potential for seed dispersal facilitation and competition among co-fruiting-plant neighbors using Solanum americanum and Cestrum diurnum, two plant species that co-occur in open habitats of Puerto Rico and whose seeds are dispersed by the same bird species. Expand
Relative importance of phenotypic trait matching and species' abundances in determining plant–avian seed dispersal interactions in a small insular community
TLDR
Although the best way to predict plant-avian interactions was based on both phenotypic traits and species abundance, the most important factor to explain these mutualistic interactions was fruit-beak size overlap, followed by species abundance and fruit nutrient compounds. Expand
Network models of frugivory and seed dispersal: Challenges and opportunities
TLDR
New research avenues to connect network models to FSD processes are outlined, and the challenges and opportunities of this tool with a field study are illustrated, to serve to spark and renew interest in FSD and further the understanding of plant–animal communities. Expand
Evolutionary ecology of pungency in wild chilies
TLDR
The results suggest that the pungency in chilies may be an adaptive response to selection by a microbial pathogen, supporting the influence of microbial consumers on fruit chemistry. Expand
Where do seeds go when they go far? Distance and directionality of avian seed dispersal in heterogeneous landscapes.
TLDR
Findings reveal the strong dependence of seed dispersal on the existing templates that guide the movements of avian dispersers in heterogeneous landscapes and also suggest that LDD above tree lines and beyond hard habitat edges can be difficult. Expand
Avian fruit preferences across a Puerto Rican forested landscape: pattern consistency and implications for seed removal
TLDR
Preference patterns, particularly those exhibiting consistency in space and time for plant species having prolonged fruiting periods, may have important mechanistic consequences for the persistence, succession, and regeneration of tropical plant communities. Expand
