Nonlinear stochastic Markov processes and modeling uncertainty in populations
Published 2011-11-01“…We consider an alternative approach to the use of nonlinear stochastic Markov processes (which have a Fokker-Planck or Forward Kolmogorov representation for density) in modeling uncertainty in populations.These alternate formulations, which involve imposing probabilistic structures on a family of deterministic dynamical systems, are shown to yield pointwise equivalent population densities. Moreover, these alternate formulations lead to fast efficient calculations in inverse problems as well as in forward simulations. …”

Florida Bromeliad Weevil (no official common name), Metamasius mosieri Barber (Insecta: Coleoptera: Curculionidae: Dryophthorinae)
Published 2003-10-01“… The Florida bromeliad weevil is an occasional and minor pest on ornamental bromeliads and occurs at very low population densities in its natural habitat. It should not be confused with the Mexican bromeliad weevil, Metamasius callizona, which is currently attacking five species of native bromeliads in 16 counties and will likely destroy populations of six additional species of already-threatened or endangered bromeliads if not brought under control. …”

Delayed population models with Allee effects and exploitation
Published 2014-11-01“…Using a delay-differential equation modeling the evolution of a single-species population subject to constant effort harvesting, we show that the interplay between harvest strength and Allee effects leads not only to collapses due to overexploitation; large delays can interact with Allee effects to produce extinction at population densities that would survive for smaller time delays.In case of bistability, our estimations on the basins of attraction of the two coexisting attractors improve some recent results in this direction. …”
