Post-dispersal fate of Quercus ilex seeds and seedlings compared between Mediterranean oak forest and savanna, since caching at 15 November 2005. Proportions shown are Kaplan-Meier survival estimates. (a) removal of seeds from artificial caches prior to seedling emergence; (b) emergence of seedlings from non-pilfered caches; (c) mortality of seedlings after emergence; note that here t = 0 reflects time since emergence, which differs between savanna and forest.
