Module Inventory

The module inventory is a quick way to see what types of plants and animals you have in your model in addition to the default abiotic modules. The "Add New ..." buttons are quick ways to introduce new plants and animals into your model.

Double click the module you want to view and this will open the next related parameter category in the Parameter View window using one of the Search mechanisms.

Introduce new plant and animal types into your model using the Add New ... buttons (see below).

Modules in your model

The above conceptual (not a class inheritance) diagram shows information flow between the main modules in your model. Climate and other atmospheric data is read into the Climate module from your data files and fed to the Soil module where soil moisture is the result of water loss from surface runoff, evaporation and deep percolation. Plant growth is calculated from soil water levels available for root uptake which is allocated to the plant parts that your animals select from to form their diet. Animal growth and population dynamics (reproduction and mortality) result from this intake which is levied back to the Plant module as removal of plant biomass. Time moderates all the other processes, stipulating a daily iteration interval and synchronizing input and output events during the course of your simulation.

The Plant module can either be considered as reproducible for each plant type that you introduce into your model or as a single entity that contains all of your plant types. It doesn't really matter other than to highlight that there is information flow (data transfer) between it and the Animal module (which can be considered in the same way, single or multiple).

However you want to think of it, it is clear that very soon building up your model with just a few plant and animals types is going to lead to quite a few potential interactions, depending on the animals' diet preferences.
Here we have 2 specialized feeders (a grazer and a browser) and a mixed feeder with 6 potential plant source diet choices, in any allowed combination, i.e., each animal can choose a daily mixed diet from their menu of preferred food plants. The fact that these selections operate at the level of plant parts (leaves, stems, fruit/seeds) and their state besides (green leaves and dead leaves, green stems and dead stems) gives you an idea of the number of permutations possible for your plants and animals depending on type and food preferences.

Module types

The minimum configuration for your model would contain the Time, Climate and Soil modules. These must be included and the modelling software will ensure that they are in place, at least with default parameter values, before you can proceed with your simulation.

The Add New ... windows are there to make it easy for you to do just, introduce new plant and animal types. They both offer default types that you can use to adapt to your needs.
