Net reproductive rate (Ro) (2)

• Download

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)

• Download

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...

Transient Dynamics. (3)

• Download

This workflow produces plots of the short-term dynamics and convergence to stable stage distribution using stage vector projections. ============================================================ 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, grant no. 283359. This workflow was created based on Package ‘popbio’ in R. Stubben, C & B. Milligan. 2007. Estimating and Anal...

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...

Eigen analysis (3)

• Download

The Eigen analysis results are a set of demographic statistics: 1) Lambda or dominant eigenvalue: The population will be stable, grow or decrease at a rate given by lambda: eg: ? = 1 (population is stable), ? > 1 (population is growing) and finally ? < 1 (populatiopn is decreasing) . 2) The stable stage distribution: It is the proportion of the number of individuals per stage and it is given by (w). Elasticity and Sensitivity: Sensitivity and elasticity analyses are prospective analyses....
