Pack Bootstrap of observed census transitions pack


Created: 2014-07-09 12:56:51 | Last updated: 2014-07-25 10:37:19

This pack contains a workflow, a file and documentation (tutorial to run the workflow).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 estimate lambda, because lambda is es...

Pack Net reproductive rate (Ro) pack


Created: 2014-07-04 13:59:07 | Last updated: 2014-07-25 11:25:32

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The . Net reproductive rate (Ro) Workflow provides an environment to calculate the net reproductive rate (Ro). Ro is the mean number of offspring by which a new-born individual will be replaced by the end of its life, and thus the rate by which the population increases from one generation to the next.

Pack Generation time (T) pack


Created: 2014-07-04 13:20:43 | Last updated: 2014-07-25 11:22:30

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Generation Time (T) Workflow provides an environment to calculate the generation time. Th generation time is the time T required for the population to increase by a factor of Ro (net reproductive rate). In other words, T calculates how much time takes to a plant/animal to replace itself by a factor of Ro.

Pack Damping ratio pack


Created: 2014-07-02 13:32:31 | Last updated: 2014-07-25 11:07:16

This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Damping ratio pack contains a workflow that provides an environment to calculate the damping ratio of several matrices and plot them.The damping ratio can be considered as a measure of the intrinsic resilience of the population, describing how quickly transient dynamics decay following disturbance or perturbation regardless of population structure, the larger the p, the quicker the population converges ...
