number of prey species

T

number of time periods

J

scalar or vector (of length T) number of predators caught at each time

I

scalar or vector (of length T) effective number of traps at each time

lambda

matrix of rates at which predator eats prey species; TxS

gamma

matrix of rates at which prey species is seen in habitat; TxS

EM
