This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.This workflow calculates the Elasticity and Sensitivity of population growth rate with respect to various vital rates. The goal in both cases is to determine which vital rate(s) has/have the most influence on population growth rate (λ).Elasticity and Sensitivity: Sensitivity and elasticity analyses are prospective analyses.The sensitivity matrix: The sensitivity desc...

Workflow Elasticity and Sensitivity of the Vital rates (1)

Thumb
This workflow calculates the Elasticity and Sensitivity of population growth rate with respect to various vital rates. The goal in both cases is to determine which vital rates has/ve the most influence on population growth rate (?). Elasticity and Sensitivity: Sensitivity and elasticity analyses are prospective analyses. a) The sensitivity matrix: The sensitivity describes the effect on ? of changes in vital rates of the matrix. The derivative tells what would happened to ? if aij was to c...

Northern Resident Killer Whale (NRKW) demographic data.The input data (a .csv-file) has to have the format of a table containing the Orcinus orca demographic data with the columns named: Year, Age, Count, Offspring and Cat1. Each year, the number of individuals per age and the number of offspring per age reproductive female category are counted (females ≥ 10 years old). IF A Female category does not have offspring equals to 0. For the called column, Cat1; Ages 1 to 9 belongs to Juv (Juveni...
