Population
Graph
Over the time the aye-aye population has grown drastically due to natural selection. The aye-aye's speciation has known to be from the lemur and there were lots of lemurs when the aye-aye first came known. But the aye-aye is outsized compared to the lemurs of Madagascar. The aye-ayes adaptations to the Madagascar rainforest have helped them survive. For example, the aye-ayes long middle finger and their large ears helped them find food. Their tails help them keep balance to climb to safety in trees. There are different variations of aye-ayes. Some have a shorter middle finger than others or really small ears. Both of these adaptations could affect their lifespan because they can't get a food source or maybe find protection.
Future Population
My prediction for the aye-ayes population would be for it to keep growing for now. Aye-ayes are endangered therefore there are people trying to help protect them and have the aye-ayes reproduce so they won't die out. The population would not decrease until most aye-ayes are out in the wild on there own, being able to protect themselves and still reproduce successfully. But there is a fair amount of them so that could potentially make them a target in the rainforest because there could be a lot of them if they keep reproducing.
Ecosystem
In the future, Aye-aye's population would only slightly alter the ecosystem. Aye-ayes eat a lot of bugs so if there wasn't an animal eating that many bugs, it could affect the bug population. If the aye-ayes did die out there would be more bugs, then they would take over the world (not really). But there would be lot more bugs around than there is now. Predators of the aye-aye like the fossa would also have to find another food source, which then affects other animals. If the aye-aye continue to produce there could be overproduction. There wouldn't be enough food for everyone to eat so then some would die.
