Resource partitioning refers to the division of resources among different species to reduce competition. In this case, the smaller mouse is likely adapting to eat different types of grass or utilizing different parts of the grass to reduce competition with the larger rodent species. This results in a difference in body size between locations with and without the larger rodent species. This is a common pattern observed in ecosystems and is an example of resource partitioning.
