| Give a brief description of the cormack jolly seber model |
|
Definition
| The CJS is a model used to estimate survival of a population based on data collected by capturing, marking, and recapturing individuals |
|
|
Term
| Provide a model diagram for the CJS |
|
Definition
|
|
Term
| List the relevant parameters calculated in the CJS |
|
Definition
| calculates survival rate between capture occasions (Phi) and probability of capture at each occasion (p) |
|
|
Term
| Give a brief definition of each parameter used in the CJS |
|
Definition
Ī¦ (Phi)- suvival rate
p- probability of capture |
|
|
Term
| Provide the encounter history format for the CJS model |
|
Definition
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) |
|
|

| Give a brief description of the Known Fate model |
|
Definition
| 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 |
|

|
|
Term
| Provide the encounter history format for Known Fate |
|
Definition
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 |

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

| 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. |
