Population dynamics: general results from local analysis [PDF]

open access: green, 2004
In this thesis a new approach to the formulation and analysis of general models is presented. In general models the interaction between state variables is not restricted to specific functional forms. Instead they are described by general functions. This approach is used to formulate and study models of general food chains and food webs.

Generational Spreading Speed and the Dynamics of Population Range Expansion [PDF]

open access: yesThe American Naturalist, 2015
Some of the most fundamental quantities in population ecology describe the growth and spread of populations. Population dynamics are often characterized by the annual rate of increase, λ, or the generational rate of increase, R0. Analyses involving R0 have deepened our understanding of disease dynamics and life-history complexities beyond that afforded

Two-mode effective interaction in a double-well condensate [PDF]

open access: yes, 2013
We investigate the origin of a disagreement between the two-mode model and the exact Gross-Pitaevskii dynamics applied to double-well systems. In general this model, even in its improved version, predicts a faster dynamics and underestimates the critical

Difference equations as models of evolutionary population dynamics

open access: yesJournal of Biological Dynamics, 2019
We describe the evolutionary game theoretic methodology for extending a difference equation population dynamic model in a way so as to account for the Darwinian evolution of model coefficients.
