Explore the Biomes

Move from the macro-system into the specific habitats that make up the miniBIOTA biosphere.

Engineering

Explore the six connected systems that regulate climate, water, light, motion, control, and enclosure inside the biosphere.

A Chemistry Shift in the Lake Ripples Across the Biosphere

When the plant structure in the Freshwater Lake changed, the effects didn't stay in the lake. Because the biomes share air, water, and nutrients, a shift in one habitat shows up in the others. This longform entry tracks how a transition from macroalgae dominance toward tapegrass establishment changed the lake's nutrient cycling, and what that meant for connected biomes. The ghost shrimp in the seagrass meadow, thriving for over two years, became the reference point for whether the lake could finally support the same species under sealed conditions.

The Lake Before Closure: 2025 Ecological State

In the final weeks before the Freshwater Lake was sealed into a closed biosphere, each major population had reached a working equilibrium. This longform entry documents the ecological baseline at the moment of closure: what had stabilized, what was still uncertain, and what it looked like for a freshwater system on the edge of becoming fully self-sustaining.

Chironomid Larvae Introduced: A New Decomposer Enters the Food Web

Midge fly larvae collected from an outdoor rainwater bucket were introduced to the Freshwater Lake as a potential sediment-layer decomposer. Their red coloring points to hemoglobin adaptation for low-oxygen environments, which makes them a practical fit for a detritus dweller in a sealed system. This marks the first deliberate introduction of an invertebrate chosen specifically for its role in the lake's decomposition layer.

miniBIOTA Begins

miniBOITA began as a 29 gallon terrarium tank filled with soil from the nearby forest and my favorite fern, the rabbits foot fern. I would continue to add various bits of moss and insects to observe their interactions
