Extract population details from RAMAS Metapop .mp files.
Usage
meta(mp)
Arguments
mp
A character string containing the path to a RAMAS Metapop .mp file
containing simulation results. Metapop .mp files are plain text files that
store settings describing RAMAS metapopulation models, and the results of
simulating population dynamics according to those models.
Value
A data.frame containing one row per population, with columns:
popName
The name of the population.
xMetapop, yMetapop
The spatial
coordinates of the population centroid, in RAMAS's coordinate system (see
mp2xy).
initN
The initial abundance.
ddType
The density dependence type.
Rmax
The maximum
growth rate.
K
The initial carrying capacity.
Ksd
The standard deviation in K, if applicable.
allee
The allee parameter, if applicable.
kch
A constant, or
reference to a .kch file describing temporal change in K.
ddDispSourcePopN
The parameter indicating the effect of source
population abundance on its dispersal rate.
cat1LocalMulti
The
local multiplier for probablity of Catastrophe 1, if applicable.
cat1LocalProb
The local probability of Catastrophe 1, if
applicable.
includeInTotal
Indicates whether abundance of this
population is included in totals reported in simulation results.
stageMatrix
The name of the stage matrix in use by the population.
relFec
The mean fecundity of this population, relative to those
given in the stage matrix.
relSurv
The mean survival rates of this
population, relative to those given in the stage matrix.
localThr
The abundance threshold below which the population might be
considered dead (depending on global options specified elsewhere).
cat2LocalMulti
The local multiplier for probability of Catastrophe
2, if applicable.
cat2LocalProb
The local probablity of Catastrophe
2, if applicable.
sdMatrix
The name of the standard deviation
matrix in use.
ddDispTargetPopK
The target population K below which
dispersal out of this population is reduced.
tSinceCat1
The number
of time steps since this population last experienced Catastrophe 1.
tSinceCat2
The number of time steps since this population last
experienced Catastrophe 2.
relDisp
Dispersal rates of this
population relative to those specified by the global dispersal
matrix/function.
relVarFec
Variation in fecundity rates of this
population, relative to those given in the standard deviation matrix.
relVarSurv
Variation in survival rates of this population, relative
to those given in the standard deviation matrix.
