In this video we take a look at the terrarium my brother made during his childhood. This terrarium was made between 2007 – 2008. This makes the terrarium at least 12 years old.
Two worlds coexist in this sealed ecosystem: Above, isopods live on rocky terrain with plants and a small lurking predator species: Centipedes. Below, algae, moss, and fungi thrive, providing a home for springtails, nematodes, and other invertebrates. This Jartopia video observes these lifeforms and reflects on how they have survived for generations within the closed ecosystem.
Originally this terrarium was home to a lot more plant and isopod species, however as the years went by biodiversity was lost as the new ecosystem balanced out.
Currently the ecosystem is experiencing cycles. As the plant population increased, so did the isopods. This caused the isopod population to graze on a lot of the terrariums plants, causing the plant population to decrease. I imagine centipede populations may increase in future giving the plants the opportunity to recover.
