This paper describes the use of a dynamical simulation model to evaluate various management policies in a two-stage production systems. Such a simulation-based evaluation is applied to the situation of GrandIlet (Reunion Island) where 51 pig farms must supply a collective treatment plant (CTP) with pig slurry.

Appendages consisted of aggressive calls and segments of advertisement calls from conspecific males and males of three oth...

This study introduces advertisement into the dynamic nonlinear duopoly model. It demonstrates three major findings. The first is that the model can be destabilized via either flip bifurcation or Hopf bifurcation, the second is that a half-pitchfork bifurcation of output occurs when the advertisement dynamics is periodic and the nonlinearity of the output dynamics becomes stronger, and the third...

Existing theory predicts that male signalling can be an unreliable indicator of paternal care, but assumes that males with high levels of mating success can have high current reproductive success, without providing any parental care. As a result, this theory does not hold for the many species where offspring survival depends on male parental care. We modelled male allocation of resources betwee...

During September 1969 the author visited both Mauritius with peaks not much higher than 1000 latest technical developments on those two islands.
