Vellend, M. (2002) A pest and an invader: White-tailed deer (Odocoileus virginianus Zimm.) as a Seed dispersal agent for honeysuckle shrubs (Lonicera L.). Natural Areas Journal, 22(3):230-234. (Scopus )

Résumé

Predicting and managing the spread of invasive plant species require a sound and detailed knowledge of dispersal mechanisms. I examined white-tailed deer (Odocoileus virginianus Zimm.) feces in five mature forest stands in central New York, USA, and found seeds of alien invasive bush honeysuckles (Lonicera tatarica L., L. morrowii A. Gray, L. × bella Zabel) in feces from all five stands. Lonicera seeds were found in 66 of 72 pellet groups examined, and the overall mean number of seeds per pellet group was 62 ± 19 SE; within-stand means ranged from 0.6 ± 0.3 SE to 334 ± 165 SE. Percent germination of seeds collected in feces from one site was 76%, compared to 81% for fresh-collected seeds, and Lonicera seedlings were observed growing out of feces in the field. Prior to this study, the only important dispersers recognized for invasive Lonicera spp. have been birds. Using data from the literature on the feeding, digestive, and movement behaviors of deer vs. birds, I show that white-tailed deer have tremendous potential for contributing to the spread of invasive honeysuckles and perhaps other plant species.
