Provide the encounter history format for the CJS model

A list of 0s and 1s where

0= no capture of that idvidual for that occasion

1= capture for that individual for that occasion

followed by Xw (the number of individuals that hat that exact encounter history or frequency)

Provide and interpret and example encounter history for 6 idviduals in the CJS format

011001 4;

000100 2;

Provide an example/imaginary data set that would be appropriate for the CJS
Estimating survival rate of Alligator Gar in a backwater habitat on the Trinity using gill nets and electroshocking techniques
Give a brief description of the Known Fate model
A model that asses survival rates of a population that is baed on data in which the death of the death of an animal is known
provide a model diagram for Known Fate
[image]
List the relevant parameters calculated and the definition of each parameter for Known Fate
Known Fate calcualtes S_hat which is an estimate of the survival rate
Provide the encounter history format for Known Fate

The enoucnter history format is based on wether the individual was alive or deadduring a time interval followed by Xw-the number of individuals that have that exact same encounter history (frequency)

10- found and didn’t die

11- found and was dead

01- invalid b/c animal cant be counted dead if not ever found

00- animal either not captured yet or not accounted for during time interval in question

Provide and interpret an example encounter history format for 5 individuals for Known Fate

00 10 10 11 1; caught 2nd and 3rd interval, died in 4th

11 00 00 00 1; caught and died in first interval 

10 10 10 10 1: caught in all intervals

00 10 00 11 1; caught in 2nd interval, died in 4th

10 00 00 00 1; caught in first interval and not captured again

Provide an example/imaginary data set that would be appropriate for Known Fate
This could be used to estimate survival of radio tagged chupacabras in the Lubbock area. They are here and they are eating all the poor Cat Ladies’ cats.
