Matrix Population Model analysis v12 (2)

• Download

The Matrix Population Models Workflow provides an environment to perform several analyses on a stage-matrix with no density dependence: - Eigen analysis; - Age specific survival; - Generation time (T); - Net reproductive rate (Ro); - Transient Dynamics; - Bootstrap of observed census transitions (Confidence intervals of lambda); - Survival curve; - Keyfitz delta; - Cohen's cumulative distance. This workflow requires an instance of Rserve on localhost This workflow has been created by the Bi...

The Matrix Population Models Workflow provides an environment to create stage-matrices with no density dependence and to perform several analyses on them: - Eigen analysis; - Age specific survival; - Generation time (T); - Net reproductive rate (Ro); - Transient Dynamics; - Bootstrap of observed census transitions (Confidence intervals of lambda); - Survival curve; - Keyfitz delta; - Cohen's cumulative distance. If multiple year transitions are selected, the results will be ordered by year. ...

Net reproductive rate (Ro) (2)

This workflow calculates the net reproductive rate (Ro) that is mean number of offspring by which a newborn 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 (Caswell, 2001) =============================================================== This workflow has been created by the Biodiversity Virtual e-Laboratory (BioVeL http://www.biovel.eu/) project. BioVeL is funded by the EU’s Seventh Framework Program, gr...

Generation time (T) (2)

The time T required for the population to increase by a factor of Ro (net reproductive rate) e.g.: If Ro (net reproductive rate) = 5.56 and T (generation time) = 8.055 The average plant of the species Gentiana pneumonanthe in Terschelling in the year 1987 replaced itself with almost six new plants and took approximately 8.05 years to do so. ========================================================= This workflow has been created by the Biodiversity Virtual e-Laboratory (BioVeL http://www.bio...

Age specific analysis (3)

• Download

The age specific analysis workflow gives the basic information on age-specific survival, this includes the mean, variance and coefficient of variation (cv) of the time spent in each stage class and the mean and variance of the time to death. Fundamental matrix (N): is the mean of the time spent in each stage class. Variance (var): is the variance in the amount of time spent in each stage class. Coefficient of variation (cv): is the coefficient of variation of the time spent in each class...
