Population consequences of environmental sex reversal.
When sex determination in a species is predominantly genetic but environmentally reversible, exposure to (anthropogenic) changes in the environment can lead to shifts in a population's sex ratio. Such scenarios may be common in many fishes and amphibians, yet their ramifications remain largely unexplored. We used a simple model to study the (short-term) population consequences of environmental ...
متن کاملPopulation dynamic consequences of allee effects.
We take a well-known dynamic model of an isolated, unstructured population and modify this to include a factor that allows for a reduction in fitness due to declining population sizes, often termed an Allee effect. Analysis of the behaviour of this model is carried out on two fronts - determining the equilibrium values and examining the stability of these equilibria. Our results point to the st...
متن کاملPopulation Consequences of Releasing Sex-reversed Fish: Applications and Concerns
1. Abstract Sex differentiation is generally more labile in gonochoristic fish than it is, for example, in birds and mammals. Environmentally induced sex reversal is therefore often possible and creates genotype-phenotype mismatches that can be useful in population management. Interestingly, sex chromosomes of fish are typically not significantly decayed, i.e. all types of offspring of sex-reve...
متن کاملHybrid Matrix Models and Their Population Dynamic Consequences
In this paper, the main purpose is to reveal what kind of qualitative dynamical changes a continuous age-structured model may undergo as continuous reproduction is replaced with an annual birth pulse. Using the discrete dynamical system determined by the stroboscopic map we obtain an exact periodic solution of system with density-dependent fertility and obtain the threshold conditions for its s...
