Marten+ODD+protocol

= = Overview

Purpose
The purpose of this model is to synthesize available data from existing literature regarding the behavior of the American Marten (//Martes americana//) and to implement this behavior in an individual-based model. This model will then be used to project the success or failure of Marten populations in Vilas County, Wisconsin, a location where Marten populations have been declining, and reintroduction programs have been put into place. This model will be used to 1) determine what factors appear to be influencing the fate of the population, and 2) test what effects potential land-use change scenarios may have on Marten populations.

Entities
Entities in this model include agents which represent the individuals of the Marten population, a small mammal layer which represents the food source for the Martens, and the TrailsForward environment which is a spatially-explicit dynamic representation of forest cover and human development on the landscape.

Marten

 * Immutable to a single agent
 * sex
 * parent id's
 * base metabolic rate
 * Updated infrequently
 * reproductive status
 * infertile
 * immature
 * kit-rearing
 * fertile
 * pregnant
 * age
 * Updated frequently
 * caloric budget
 * fat reserves
 * current metabolic rate (seasonal adjustment?)
 * prey input

Landscape inputs

 * Forest
 * Not certain what is needed/relevant:
 * dominant shade tolerance
 * intolerant
 * mid-tolerant
 * tolerant
 * diameter distribution (2cm classes)
 * mean dbh
 * measure of cwd?
 * Development
