MigConnectivity: A package for quantifying migratory connectivity pattern and strength for migratory animals
Description
The MigConnectivity package allows the user to estimate or calculate
transition probabilities for migratory animals between any two phases of the
annual cycle, using a variety of different data types, with the function
estTransition
. The user can also estimate or calculate the
strength of migratory connectivity (MC), a standardized metric to quantify
the extent to which populations co-occur between two phases of the annual
cycle. MC is independent of data type and accounts for the relative abundance
of populations distributed across a seasonal range. The package includes
functions to estimate MC (estStrength
) and the more traditional
metric of migratory connectivity strength (Mantel correlation; rM;
estMantel
) incorporating uncertainty from multiple
sources of sampling error. Description of the MC metric can be found in Cohen
et al. (2018).
Key MigConnectivity Functions
estTransition
: Estimate psi (transition probabilities between
locations in two phases of the annual cycle)
estStrength
: Estimate MC, migratory connectivity strength
