population_modification_functions: How the population is modified in a landscape.

Description Usage Arguments Examples

Description

Pre-defined functions to define population modification (e.g. translocation) during a simulation.

Usage

1
2
translocation(source_layer, sink_layer, stages = NULL,
  effect_timesteps = 1)

Arguments

source_layer

the name of a spatial layer in the landscape object with the locations and number of individuals to translocate from. Note, this layer will have only zero values if individuals are being introduced from outside the study area

sink_layer

the name of a spatial layer in the landscape object with the locations and number of individuals to translocate to. Note, this layer will have only zero values if individuals are being controlled (e.g. culling)

stages

which life-stages are modified - default is all

effect_timesteps

which timesteps in a single simulation do the translocations take place

# Use the translocation_population_dynamics object to modify the  
# population using translocations:

test_translocation <- translocation(source_layer = "egk_source",
                                       sink_layer = "egk_sink",
                                       stages = NULL,
                                       effect_timesteps = 1)
