Randomized trial investigates how seed traits and relative abundance affect foraging preferences in rodents, suggesting key ecological impacts.

This research aims to explore how relative abundance and seed traits influence the foraging decisions of scatter-hoarding rodents.
Conducted a field experiment in a subtropical forest with 19,200 artificial seeds of varying sizes and tannin content.
Deployed seeds across 240 patches with five relative abundance levels to assess seed removal patterns.
Measured seed removal, caching probability, and dispersal distance in relation to seed traits and frequency.
Large seeds were removed less frequently as their relative abundance increased; smaller seeds showed the opposite pattern.
Frequency-dependent responses were also noted for tannin treatments, with effects varying based on context.
Caching probability and dispersal distance were largely unaffected by the relative frequency of seeds.
