Seed retention times in New Zealand’s largest gecko, Hoplodactylus duvaucelii, and implications for seed dispersal

Fruit is an important component in the diet of many lizards, but their role as seed dispersers is often overlooked. Seed retention time and animal movement determine how far a fleshy fruited seed will be dispersed from the parent plant. Seed retention times were investigated in 78 captive Hoplodactylus duvaucelii (Duvaucel’s geckos). Geckos were offered fruits from 10 plant species. Fifty-one geckos consumed fruits and the mean seed retention time was 69 hours (range 31 to 145 hours).
