Fig. 2: Allee-like behavior of the H cells.

a, b Birth rate (9) + (6) of H cells (orange) and death rate (5) of H cells (blue) versus H density. The characteristic s-shape of a birth rate in a population with Allee effect is visible. a Rates in absence of the analyte (σ = 0.1 h⁻¹). b Rates in presence of the analyte (σ = 5 h⁻¹). Parameters used: κ = 35 h⁻¹, ρ = 14 h⁻¹, P = 2 ⋅ 10⁸ mL⁻¹, n = 4.
