Pack Relative importance of Chinook salmon abundance on r...


Created: 2014-08-29 11:04:10 | Last updated: 2014-09-30 09:35:02

The pack contains three workflows, 13 files and 2 documentations (tutorials to run the workflows).Workflows:1) Demography of the killer whales.2) Resident killer whale-chinook salmon interactions.3) Exploration of fishing scenarios.These workflow uses input data of two different populations of Orcas in the northeastern Pacific Ocean of Canada and the U.S. But these workflows can also use input data from other populations of the Orcas in the world (see requirements for data entry in the docume...

Pack Cohen cumulative distance pack


Created: 2014-07-23 13:43:22 | Last updated: 2014-07-24 08:21:00

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Cohen’s cumulative distance Workflow provides an environment to calculate the Cohen’s cumulative distance. The Cohen’s cumulative distance measures the difference between observed and expected vectors along the matrix path that the population would take to reach the expected population vector. It is a function of both the observed stage distribution (n0) and the structure of the matrix...

Pack Keyfitz's delta pack


Created: 2014-07-23 11:19:37 | Last updated: 2014-07-24 08:25:22

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Keyfit delta Workflow provides an environment to calculate the Keyfit delta value. Keyfitz’s delta is a measure of the distance between any two probability vectors (Keyfitz 1968). In this case is a measure of the distance between n (Observed Stage Distribution) and w (Stable Stage Distribution). The maximum value is 1 and the minimum value is 0 (when the vectors are identical).

Pack Eigen analysis pack


Created: 2014-07-03 15:57:49 | Last updated: 2014-07-25 11:18:57

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Eigen analysis workflow provides an environment for the analysis of a stage-matrix and perform several analyses on it.The Eigen analysis results are a set of demographic statistics:Lambda or dominant eigenvalue (λ).The stable stage distribution (w).The sensitivity matrixThe Elasticity matrix.Reproductive value (v).The damping ratio (ρ).
