Summary of parameters used

Parameter	Definition	Comments
α	Habitat carrying capacity	Dimensionless unit The natural habitat carrying capacity α was set to two units
β	Red-eared slider survivorship, affected by habitat condition	–1 < β < 1 Positive values closer to zero represent better conditions for red-eared slider survivorship. Negative values indicate habitat increase by natural spread of sliders
x_n	Population at the beginning of the n^th year	Dimensionless unit Initial population for time interval [n, n + 1]
y_n = α – βx_n	Effective habitat carrying capacity	Dimensionless unit Constant habitat carrying capacity for time interval [n, n + 1]
