As an AI language model, I am not capable of predicting or guessing specific keystone species. However, generally speaking, a keystone species is one that has a disproportionately large impact on its ecosystem relative to its abundance. This can include apex predators that keep prey populations in check, pollinators that are critical to plant reproduction, or even decomposers that help recycle nutrients. Some examples of keystone species include wolves, sea otters, bees, and dung beetles.
