TABLE 1.

Life history parameter values used to calculate the potential for population increase (r) for the short and long lifespan scenarios

Lifespan	Parameter	Minimum	Deterministic value	Maximum
Short	Age at maturity	8	9.5	11
Short	Female litter size	2	4	6
Short	Gestation period	2	2.5	3
Short	Maximum age	35	40	45
Short	Natural mortality	0.062	0.112	0.162
Long	Age at maturity	25	30	35
Long	Female litter size	2	4	6
Long	Gestation period	2	2.5	3
Long	Maximum age	60	70	80
Long	Natural mortality	0.053	0.063	0.073

The median was taken as the deterministic value and the minimum and maximum provide the range used in Monte‐Carlo sampling.
