Dialogue box for help setting up a parameter list
Optional parameters to use as defaults in clicky box.
Creates a minimal set of parameters necessay to run simulations and analysis. Additional arguments can be added to the outputted list as needed.
|Initial population size||Population size at the start of the simulation|
|Population growth rate||Annual population multiplication rate (Lambda=N_t/N_0)|
|Number of years||Maximum number of years for the simulation|
|Number of types||Types of individuals to treat separately in the population simulation|
|Proportion of population||Proportion of population in each individual-type (e.g. sex ratio)|
|Buffer distance||Minimum distance between movement centers for each type of individual|
|Movement radius|| With
|Proportions of movements within radius||With movement radius, used to define bivariate normal use distribution|
|Truncation||Limits to long-distance movements (proportion of movement distribution to allow)|
|Cell size||Area of grid cell|
|Minimum habitat value||Cutoff value for where individual centers should be located|
|Minimum sampling value||Cutoff for home much habitat must be included in cell to sample|
|Number of visits||Maximum number of visits to each grid cell per year|
For parameters defining movement distribution, estimates may be drawn from either movement studies (e.g., step lengths), home range studies (e.g., minimum convex polygon, kernal estimates), or expert opinion. These parameter estimates should reflect expected movement during the sampling season only. For some species (e.g., a wide-ranging species such as wolverine), an individual may be reasonably expected to potentially visit any location in its home range during the sampling season; however, this is not always expected to be the case.
