Differential contribution of frugivores to complex seed dispersal patterns.
Frugivores are highly variable in their contribution to fruit removal in plant populations. However, data are lacking on species-specific variation in two central aspects of seed dispersal, distance of dispersal and probability of dispersal among populations through long-distance transport. We used DNA-based genotyping techniques on Prunus mahaleb seeds dispersed by birds (small- and medium-siz...
متن کاملConnecting Resource Tracking by Frugivores to Temporal Variation in Seed Dispersal Networks
Mutualistic interactions between species are crucial for the maintenance and functioning of the community. Current research has shown the importance of not only understanding the structure of these mutualistic interaction networks but also their temporal dynamics. Temporal changes in species abundance, such as those caused by vertebrate resource tracking, may create temporal variability in a ne...
متن کاملSeed Dispersal of a High Quality Fruit by Specialized Frugivores: High Quality Dispersal?1
Dispersal quality, as estimated by the cumulative effects of dispersal, germination, seed predation, and seedling survival, was examined for Beilschmiedia pendula (Lauraceae) in Monteverde, Costa Rica. I determined the pattern of dispersal by finding seeds deposited by birds, protected the seeds from seed predators with cages to assess germination and seedling survival, and examined seed predat...
متن کاملFrugivores and seed dispersal: mechanisms and consequences for biodiversity of a key ecological interaction.
The 5th Symposium on Frugivores and Seed Dispersal, held in Montpellier (France), 13-18 June 2010, brought together more than 220 researchers exemplifying a wide diversity of approaches to the study of frugivory and dispersal of seeds. Following Ted Fleming and Alejandro Estrada's initiative in 1985, this event was a celebration of the 25th anniversary of the first meeting in Veracruz, Mexico. ...
متن کاملObserving Seed Removal: Remote Video Monitoring of Seed Selection, Predation and Dispersal
What happens to seeds once they have reached a surface – here referred to as post-dispersal seed fate (cf. Chambers and MacMahon, 1994) – is becoming an increasingly important question. A large body of literature is available evaluating postdispersal seed fate (reviewed in Hulme, 1998, 2002; Crawley, 2000; Moles and Westoby, 2003; see Hulme and Kollmann, Chapter 2, this volume; Vander Wall and ...
