Member Function Documentation

BeginStep()

void Hare_Male::BeginStep ( void  )

virtual

BeginStep for Hare_Male.

Resets the day's activity counter and checks for default mortalities and potentially extra mortalities. Calculates energy usage for movement based on todays weight.
Also contains optional code designed to test for disease and size related death probabilities - part of the POM exercise
Unlike younger classes this method also tests for reaching the end of physiological lifespan

Reimplemented from Hare_Juvenile.

st_Foraging()

Male Foraging.

Foraging code for the Hare_Male.

Foraging time is reduced dependent upon the density of hares in the local area. There are a number of options for calculting this effect used in the POM

Step for Hare_Male.

Step controls all the state/transition behaviour for the male hare.
Has some optional code for dispersal related mortality for use in POM testing.
