make_iteroparity R Documentation
Estimate rate of iteroparity for American shad from
latitude based on Leggett and Cascardden (1978) and
Bailey and Zydlewski (2013).
Description
Function used to extract river-specific latitude
from built-in data sets.
Usage
make_iteroparity(latitude)
Arguments
latitude
Latitude, in decimal degrees. Can be queried for
each river using make_lat.
Value
Probability of repeat spawning. A numeric vector
of length = 1.
