This documentation contains the tutorial to run two related workflows. 1.    Resident killer whale-chinook salmon interactions workflow The Resident killer whale-chinook salmon interactions workflow provides an environment to create calculate a two-sex stage-structured matrix with no density dependence and with vital rates as random variables or as functions of Chinook abundance from specific stock aggregates and to (i) quantify the differences in demographic rates be...

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.The Bootstrap of observed census transitions (confidence intervals of λ) workflow for local execution calculates bootstrap distributions of population growth rates (λ), stage vectors, and projection matrix elements by randomly sampling with replacement from a stage-fate data frame of observed transitions. The goal of a demographic analysis is very often to est...

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.The Parametric Bootstrap or Resample a projection matrix Workflow provides an environment to resample a projection matrix using a multinomial distribution for transitions and a log normal distribution for fertilities (Stubben, Milligan, and Nantel. 2011). The resample is based on number of plants surveyed. The projection matrix A is first split into separate transition and ...
