Isolation by distance and stochastic migration in a fragmented population of Prosopis alba
(Botanical Society of America, 2017-02)
PREMISE OF THE STUDY: Gene flow through dispersal of seeds and pollen is a fundamental determinant of spatial genetic structure (SGS) in natural populations of trees at different spatial scales. Within continuous populations, ...
Stochastic dynamics in exotic and native blowflies: an analysis combining laboratory experiments and a two-patch metapopulation model
(Springer, 2007-07-01)
In this study we explored the stochastic population dynamics of three exotic blowfly species, Chrysomya albiceps, Chrysomya megacephala and Chrysomya putoria, and two native species, Cochliomyia macellaria and Lucilia ...

Migration, poverty, and housing in honduras
(Universidad de Chile. Facultad de Economía y Negocios, 2004-06)
Welfare comparisons may be sensitive to the assumptions made about economies
of scale within households. This paper uses recent advances in sequential
stochastic dominance techniques to show how to test for the robustness ...
Solving the migration–recombination equation from a genealogical point of view
(Springer Heidelberg, 2021)
We consider the discrete-time migration–recombination equation, a deterministic,
nonlinear dynamical system that describes the evolution of the genetic type distribution
of a population evolving under migration and ...
Avoiding extinction by migration: The case of the head louse
(World Scientific, 2015-05-15)
The possibility of spreading by migration, colonizing new spatial domains suitable for development and reproduction, can substantially relieve a biological population from the risk of extinction. By means of a realistic ...
Dynamic behavior, stochasticity and enviromental heterogeneity in Tribolium castaneum
(Universidade Estadual Paulista (Unesp), 2008)
In this study we analyzed the influence of demographic parameters on the population dynamics of Tribolium castaneum, combining empiricism and population theory to analyze the different effects of environmental heterogeneity, ...
