Pairing gut content analysis of arthropods with protein-marking of seeds revealed a much more diverse community of post-dispersal granivores than has previously been predicted for a single seed species. Linkage strength of particular granivores did not always correlate well with seed removal rates, potentially due to the fact that relative densities of these taxa were not well measured by pitfall traps. The method of seed marking thus has merit as a tool used in conjunction with other methods (e.g., seed removal, laboratory feeding trials, etc.) to help resolve which species are potentially important granivores of plants.
