Workflow Transient Dynamics. (3)

Thumb
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...

Workflow Age specific analysis (3)

Thumb
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...

Workflow Eigen analysis (3)

Thumb
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....

Workflow Creation of a stage matrix model from demo... (2)

Thumb
This workflow create a stage matrix model based on two years census data of tagged or mapped individuals of an animal or plant population. Each annual census describes for each individual its life stage, reproductive output (estimated number offprings) and whether or not it is a new recruit. The workflow converts this data into a stage matrix model from 1 year to 2 that contains transitions probabilities from each stage to the next. This workflow has been created by the Biodiversity Virtual...
