Add New Animal

Adding an animal type, typically another species, could not be easier. Just select the type you want and press OK. The new entry will be automatically inserted into the parameter list with a set of default parameters based on animal mass that you can modify to make the new animal type different if there are already other types in your model.

Animals types are added to your model defined by the mass of a mature male of that species. This is then used to derive several important parameter values using body-size relations (allometry).

You can chose from the following animal species (listed with their mature male mass),
  • Thomsons Gazelle 13 kg
  • Grants Gazelle 25 kg
  • Impala 45 kg
  • Goat 53 kg
  • Sheep 53 kg
  • Nyala 60 kg
  • East African Oryx 150 kg
  • Greater Kudu 215 kg
  • Wildebeest 215 kg
  • South African Oryx 225 kg
  • Hereford Cattle 225 kg
  • Sable 230 kg
  • Zebu Cattle 300 kg
  • Cattle 476 kg
  • Eland 575 kg
  • Buffalo 625 kg

    or define your own animal type by the mass of a mature male.

By adding a new animal type to your model you are extending by one the array that stores all of your animals. There is therefore just the one container, 1 for all animal types.
This is a class inheritance diagram from Derry (1998) showing how properties are included down an object-oriented hierarchy (oddly in the opposite direction to the arrows). This clarifies why you might consider your plant and animal modules as containers or individual plant and animal types as discussed in the notes for the Module Inventory window, but as long as you appreciate that your animal types are characterized by their body mass and that this is one way to add new types to your model, then this is unnecessarily technical detail for just building your models and running your simulations.

The other way to add new animal types is by simply increasing the parameter value for the number of herbivores you want to include in your model using the Parameter View window, i.e., navigate to the Animals parameter category and increment the total count of Herbivore species that you will find there. Update your model using the Simulation controls in the Main Control Panel and you will see a new parameter category appear for the extra animal types. This will work for any number of extra animal types, but then you have to be able to modify their parameters to make them different, otherwise just the single entry is required.
