The Potential for Seed Dispersal by the Banana Slug (Ariolimax columbianus)

摘要: Abstract We observed wild banana slugs (Ariolimax columbianus) eating fruits of several Pacific Northwest plant species. Slime trails and direct observations indicated that are capable reaching the many plants. This motivated us to test hypothesis may act as seed dispersers, provided they defecate viable seeds. fed captive Rubus spectabilis, R. discolor, Vaccinium ovatum, V. parvifolium, Gaultheria shallon Disporum smithii determine effects slug ingestion on germination. At least some seeds each species germinated after were consumed by slugs, but germination species-specific. Seeds spectabilis less likely germinate passage through guts we found significant evidence two fruit color morphs reacted differently over time. did not statistically differ in behavior between treatments, although trend su...
