Detailed Description

The class for male voles.

Contains all the behaviour specific to the male vole. Only st_Infanticide and st_JuvenileExplore are specific to the male, other behaviours differ only in details from the female.

Dispersal()

VoleDispersalReturns Vole_Male::Dispersal ( double  p_OldQual, int  p_Distance  )

Male vole dispersal behaviour.

Works like female dispersal - but a return code of 3 will trigger infanticide
Checks p_Distance away to see if it can find a territory in the next MHabQualThreshold category or with
an improved quality of 1.1* p_OldQual if already in optimal habitat
This entails some risk though, so there is a fixed increase in the mortality chance when it does this.

{
 
    // int retval = 0;
    // p_OldQuatells whether dispersal is conditional on quality or not
    // p_OldQual is set to old habitat quality or -1
    // p_Distance is the p_Distance used by the move function
    // aim is to move in a directed way traversing the landscape using the best
    // habitats

EndStep()

void Vole_Male::EndStep ( void  )

Male vole EndStep.

The EndStep is one of the three timestep divisions. This is called once for each vole after BeginStep and Step.
The main function here is to remove voles that have died during step and otherwise to grow if not at max weight. It also checks if the vole was killed due to human management and determines the potential territory size.

Male vole infanticide behaviour.

Will only enter here if have taken over a new area a reasonable distance from the old one and will only commit infanticide in 10% of his attempts in his minimum territory range.
Tells the population manager to send an infanticide message to all females in the territory.

Step()

void Vole_Male::Step ( void  )

virtual

Male vole Step.

The Step is one of the three timestep divisions. This is called repeatedly after BeginStep and before EndStep, until all voles report that they are done with Step.

Most of the behaviours are controlled by moving voles between behavioural states in Step (for other models this is also done in BeginStep and EndStep).
When a vole is done for the day it will signal this by setting m_StepDone==true. NB that a call to one behaviour may trigger a call to another behaviour on the next call to step inside the same timestep. In this way a daily cycle of activity can be undertaken.

Reimplemented from Vole_JuvenileMale.

{
  if (m_StepDone || m_CurrentStateNo == -1) return;
  switch (CurrentVState)
  {
   case tovs_InitialState:  //initial state
       CurrentVState=tovs_MEvaluateExplore;
       break;
   case tovs_MMaturation: // Maturation
       if (st_Maturation()) Setm_Mature();
       CurrentVState=tovs_MEvaluateExplore; // Eval and Explore
       break;
   case tovs_MEvaluateExplore: // Eval&Explore
       CurrentVState = st_Eval_n_Explore();
