Workflow Resident killer whale-chinook salmon inter... (1)

Thumb
The resident killer whale-chinook salmon interactions workflow provides an environment to 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 between killer whale (Orcinus orca) population that explain population growth; (ii) to determine the relative influence of vital rates and Chinook (Oncorhynchus tshawytsc...

Workflow Killer whale demography (1)

Thumb
This workflow analyzes the demography and population growth of resident killer whale populations. Originally created for comparative studies of Northeastern Pacific populations at risk, Southern Resident Killer Whales (SRKW) and the Northern Resident Killer Whales (NRKW), the workflow can be used for other killer whale populations or cetaceans counting with census data and life cycles that can be represented using the matrix models described in this document. This workflow perform the follow...

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...

Table used to define fishery impacts (FI) on Chinook abundance by stock aggregate, time lag (5YA: 5-year running average), and hypothesis (SR: Southern Resident Killer Whale; NR: Northern Resident Killer Whale) and abundance ID. FI represent ocean catch of specific Chinook stocks or stock aggregates. See below information about hypothesis.
