By June 2026, with the biosphere entering Year 7, a shared pattern emerged across all three major ecosystem zones. In the Freshwater Lake, Daphnia (Daphnia ambigua), Moina (Moina sp.), and copepods introduced in April 2026 established but did not scale. Water column stratification, with warm water in the upper half and cooler water below, may be limiting zooplankton range and reproduction even with adequate algal food supply. A heat exchanger for water circulation is in planning. In the Seagrass Meadow, cyanobacteria and Graceful Redweed (Gracilaria sp.) held ground through March into early June despite Mottled Shore Crab (Pachygrapsus transversus) grazing, turtlegrass and manatee grass introductions, sea urchin additions, and a large amphipod population converting dead shoalgrass into animal biomass. In the terrestrial and coastal systems, field crickets survived by walking to the lake to drink; grasshoppers did not, because the climate system does not yet produce morning dew on vegetation, which is how grasshoppers access water in a natural setting. The connecting observation across all three zones: nutrients arrive and are processed, but the system lacks export paths. The lake accumulates algae it cannot export. The meadow converts winter shoalgrass leaf shed into a nutrient pulse that feeds algae rather than leaving the system. The dryland atmosphere cycles moisture back from the water, but not on a daily schedule the dryland organisms can rely on. The next build phase targets water circulation in the lake and climate control for dew production as the foundation for closing these cycles.
