摘要:
Abstract: Although spatial memory and olfaction are crucial for cache recovery, the knowledge of whether scatter-hoarding rodents place different memories on caches with different seed odors is still lacking. We used Siberian chipmunk Tamias sibiricus and peanut kernel system to test how scatter-hoarding rodents trade off spatial memory and olfaction when retrieving paired artificial caches emitting either strong or weak odor. T. sibiricus preferred to first recover caches with strong odor across trials both in the impoverished and enriched env...
