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
