Abstract: Abstract The existence of two positive periodic solutions of first order functional differential equations with nondecreasing nonlinear terms is proved. The results are applied to the logistic equation of multiplicative type, the generalized Richards single species growth model, the generalized Michaelis-Menton type single species growth model, and to a model representing the dynamics of a renewable resource that is subject to Allee effects.
