feed_fun: Probability of actively questing and then finding a host
Description
Probability of actively questing and then finding a host
Usage
feed_fun(x, y, a, pref, q, tmin, tmax)
Value
Numeric vector of length 1
Arguments
x
Predictor 1 in transitions table. Numeric vector indicating host
density for each of the host species. Length should be equal to the number
of host species.
y
Predictor 2 in transitions table. Numeric vector of length 1
indicating temperature.
a
Parameter a in parameters table.
pref
Parameters named pref in parameters table. Numeric vector of
length equal to the number of host species. Values are the preference for
ticks in a given transition for each host species.
q
Parameter q in parameters table. Used in Briere function.
tmin
Parameter tmin in parameters table. Indicates minimum
temperature at which ticks actively quest.
tmax
Parameter tmax in parameters table. Indicates maximum
temperature at which ticks actively quest.
Details
Product of binomial and Briere functions
(prob of finding a host) * (prob of active questing)
