Lyapunov type inequalities for (linear or nonlinear) Hammerstein integral equations are established and applied to second order differential equations (ODEs) with general separated boundary conditions. These new inequalities provide necessary conditions for the Hammerstein integral equations and these boundary value problems to have nonzero nonnegative solutions. As applications of these inequalities for nonlinear ODEs, we obtain extinction criteria and optimal locations of favorable habitats for populations inhabiting one dimensional heterogeneous environments governed by reaction-diffusion equations with spatially varying growth rates and external forcing.

Keywords: Hammerstein integral equations, Lyapunov type inequalities, population models, extinction criteria, Allee effects, optimal favorable habitats.

(b) The optimal position with $m_{a, k}$ when $(\beta, \delta, T)\in \mathcal{D}_{4}$, where $k = 3$, $a = 1-T$, $\beta = \delta = 3$, $T = 0.3$, and $a_{1}(T) = \frac{1-T}{2} = 0.35$. (c) The optimal position with $m_{a, k}$ when $(\beta, \delta, T)\in \mathcal{D}_{5}$, where $k = 3$, $a = 1-T$, $\beta = 3$, $\delta = 3.5$, $T = 0.3$, and $a_{1}(T) = 0.6$. (d) The unimodal curve of $\eta_{1}$, as defined in (4.12), with respect to the variable $a\in[0, 1-T] = [0, 0.7]$ for $(\beta, \delta, T)$ in different area. Here, the curve, plotted by the dash line, corresponds to the parameters in (a), the curve, plotted by the solid line, to the parameters in (b), and the curve, plotted by the dotted line, to the parameters in (c)
