Estimating sex-specific dispersal rates with autosomal markers in hierarchically structured populations.
A recent study suggests that sex-specific dispersal rates can be quantitatively estimated on the basis of sex- and state-specific (pre- vs. postdispersal) F-statistics. In the present paper, we extend this approach to account for the hierarchical structure of natural populations, and we validate it through individual-based simulations. The model is applied to an empirical data set consisting of...
متن کاملOptimal sex ratios in structured populations.
In this paper, we develop a general method to determine evolutionary equilibrium sex ratios and to check evolutionary stability, continuous stability and invadability in exact genetic models with or without dominance. This method is then applied to three kinds of models for structured populations: the first one concerns Hamilton's LMC model, except that only a fraction beta of female offspring ...
متن کاملEmerging Diversity and Competition Success in Dispersal-structured Populations
Interacting particle systems can be used to study various problems in fields as diverse as condensed matter physics, chemical kinetics, population biology (individual based models), or sociology (agent based models). Insect swarms, bacterial patterns or bird flock are just a few examples of organism aggregates in real systems. An attempt to reproduce particle aggregation in the context of popul...
متن کاملDispersal, spatial scale, and species diversity in a hierarchically structured experimental landscape.
Although there has been growing interest in the effect of dispersal on species diversity, much remains unknown about how dispersal occurring at multiple scales influences diversity. We used an experimental microbial landscape to determine whether dispersal occurring at two different scales - among local communities and among metacommunities - affects diversity differently. At the local scale, d...
متن کاملForecasting spatially structured populations: the role of dispersal and scale.
We forecasted spatially structured population models with complex dynamics, focusing on the effect of dispersal and spatial scale on the predictive capability of nonlinear forecasting (NLF). Dispersal influences NLF ability by its influence on population dynamics. For simple 2-cell models, when dispersal is small, our ability to predict abundance in subpopulations decreased and then increased w...
