Attributions: Elasticity and Sensitivity of the Vital rates

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...

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.The Life Table Response Experiments Year Effect for Multiple Places workflow provides an environment to analyse two or more matrices (e.g., two or more matrices of different years from one place) at two or more different locations. The objective of this workflow is to determine the effects of the research years (2 or more) on λ. This workflow performs a fixed LTRE, o...

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.This workflow estimates by simulation the quasi-extinction probability time cumulative distribution function for a structured population in an independently and identically distributed (iid) stochastic environment. This workflow is based on the popbio package (stoch.quasi.ext - Calculate quasi-extinction threshold, Stubben, Milligan and Nantel, 2013) based on the MATLAB cod...

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.The Life Table Response Experiments Effect of Years in One Place workflow provides an environment to analyse two or more matrices from different years in one location. The objective of this workflow is to determine the effects of the research years (2 or more) in one place on λ. This workflow performs a fixed LTRE, one way design (Caswell 2001).LTRE is a retrospectiv...
