Objective: We evaluated and compared diurnal and nocturnal seed dispersal in primary and secondary sub-Andean forests in Southern Colombia. Methods: We estimated number and biomass (kg/ha) of seeds dispersed over one year (2017) using 60 fruit traps that were checked before sunrise and before sunset for 10 continuous days every two months. Results: We found that from 1 874 dispersed seeds, 55.8 % (10.9 kg/ha) were collected during the day and 44.2 % (6.39 kg/ha) at night. There were no significant differences between diurnal and nocturnal seed dispersal in number of seeds or biomass. We also found no difference in seed dispersal between primary and secondary forest over time. Within diurnal organisms, primates and fruit-eating birds appear to be primarily responsible for this ecosystem service during the day; while bats, birds (e.g. oilbirds), and probably primates did so during the night. Conclusions: Diurnal and nocturnal dispersal seem to be equal in terms of number and weight of seeds, but not in the similarity of dispersed plant species. It remains a challenge to recognize the relative importance of different fruit-eating organisms as seed dispersers using fruit trap methods. 2023 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44975700045 https://www.redalyc.org/journal/449/44975700045/ https://www.redalyc.org/journal/449/44975700045/html/ https://www.redalyc.org/journal/449/44975700045/44975700045.epub https://www.redalyc.org/journal/449/44975700045/movil 10.15517/rev.biol.trop..v71i1.51599 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.1 Vol.71 |
