Bioluminescent Bay Ecosystem Dynamics

Explore the factors affecting the carrying capacity of Pyrodinium bahamense, the dinoflagellate responsible for Puerto Rico's glowing bays.

Bay Simulation

Current Population: 0 cells/L

Carrying Capacity (K): 0 cells/L

Mathematical Model (Logistic Growth)

ΔP/Δt = r · P(1 - P / K) - F · P

P: Population Density | r: Intrinsic Growth Rate (dependent on Temp/Salinity)

K: Carrying Capacity (dependent on Mangrove Nutrients)

F: Flushing Rate (dependent on Bay Mouth Width & Tidal Exchange)

Environmental Factors

100%

Dictates carrying capacity (K) by providing essential Vitamin B12.

Narrow

A narrow mouth traps dinoflagellates. A wide mouth flushes them out to sea (F).

Low

Doesn't kill dinoflagellates, but drastically reduces visible bioluminescence.

Disturbance Events

Simulates storm surge widening the bay mouth and damaging mangroves.
