Freshwater Lake
Fully aquatic freshwater biome.
A still freshwater habitat where submerged plants, suspended algae, microcrustaceans, shrimp, snails, and crayfish are reorganizing after fish removal.

Ghost shrimp graze biofilm and surface growth while foraging.
Ghost Shrimp dietary inputs include algae, biofilm, detritus, and small organic particles.
Ghost shrimp consume detritus and small organic material.
Ghost Shrimp dietary inputs include algae, biofilm, detritus, and small organic particles.
Ghost shrimp help process suspended organic particles while feeding.
Ghost Shrimp feed on small organic particles and suspended material while foraging.
Daphnia filter suspended algae and planktonic food from the water column.
Daphnia record identifies filter feeding and suspended-algae grazing.
Slough crayfish consume detritus and edible organic material.
Slough Crayfish dietary inputs include plants, snails, worms, and generally edible organic material.
Before removal, fish predation likely suppressed visible microcrustaceans in the lake.
The lake post-seal story documented fish removal as a reset of microcrustacean predation pressure.
Calanoid copepods can filter fine suspended algae and planktonic particles.
miniBIOTA observations 188 and 197 document copepods in the lake water column; calanoid feeding role is based on general ecology.
Cyclopoid copepods may use planktonic algae and fine suspended food resources.
miniBIOTA observations 188 and 197 document copepods in the lake water column; cyclopoid diets vary by species and life stage.
Slough crayfish have been observed feeding from rooted lake plants below the substrate.
Observation 204 documented crayfish digging beneath substrate to consume Sagittaria roots.
Slough crayfish can graze edible surface growth while foraging across the lake floor and plants.
Species diet and observed foraging support surface grazing, but direct biofilm grazing is not yet directly documented.
Before removal, the flagfish likely consumed small water-column crustaceans.
Chronicle 30 and pipeline 338 document fish removal to reduce microcrustacean predation pressure.
Before removal, the flagfish likely added predation pressure on small copepods.
Chronicle 30 and pipeline 338 document fish removal to reduce microcrustacean predation pressure.
Before removal, flagfish helped graze visible surface growth and biofilm.
Observation 247 notes surface biofilm accumulation after fish removal, preserving previous fish grazing pressure as historical context.
Asian clams previously filtered suspended algae before disappearing from the system.
Asian clam species diet lists suspended algae; species status is extirpated.
Asian clams previously contributed to water-column filtering of fine suspended material.
Asian clam filter-feeding ecology and miniBIOTA extirpated status support this historical row.

Decomposing organic matter can help support microbial and biofilm growth on lake surfaces.
Detritus accumulation is documented; microbial and biofilm support is inferred nutrient cycling.
Decomposition can return nutrients that support suspended algae and microbial production.
General nutrient cycling plus observed green-water and suspended algae context, including observation 245.
