Costly defense traits in structured populations
Martin Hutzenthaler, Felix Jordan, Dirk Metzler
We propose a model for the dynamics of frequencies of a costly defense trait. More precisely, we consider Lotka-Volterra-type models involving a prey (or host) population consistin…
Genetic diversity in introduced populations with Allee effect
Meike J. Wittmann, Wilfried Gabriel, Dirk Metzler
A phenomenon that strongly influences the demography of small introduced populations and thereby potentially their genetic diversity is the Allee effect, a reduction in population…
Population genetic consequences of the Allee effect and the role of offspring-number variation
Meike J. Wittmann, Wilfried Gabriel, Dirk Metzler
A strong demographic Allee effect in which the expected population growth rate is negative below a certain critical population size can cause high extinction probabilities in small…
Ecological and genetic effects of introduced species on their native competitors
Meike J. Wittmann, Martin Hutzenthaler, Wilfried Gabriel +1
Species introductions to new habitats can cause a decline in the population size of competing native species and consequently also in their genetic diversity. We are interested in…
