Exploration of fishing scenarios (1)

• Download

This workflow must run after the workflow: Resident killer whale-chinook salmon interactions. The interaction workflows generates a PostWorkspace file, this is a zip file and it is an R Workspace that transfers values from the Resident killer whale-chinook salmon interactions (main) workflow to the Exploration of fishing scenario (post-processing) workflow. This workflow merges statistical inference derived from linkages between RKW vital rates (survival probability and fecundity rates) a...

Killer whale demography (1)

• Download

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...

Elasticity and Sensitivity of the Vital rates (1)

• Download

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...
