closed pop assumption
MARK will estimate this for open populations |

| Cormack Jolly Seber Assumptions |
|
Definition
- Homogeneity of capture and survival probabilities for marked animals within each sample occasion
- Instantaneous recapture
- release Emigration is permanent

| Dead Recoveries difference from CJS |
|
Definition
| no need to calculate recapture probabilities and need estimate of prob of tag recovery |
|
|
Term
| Dead recovery analysis requires the following |
|
Definition
—2 periods (2 years recommended)
—5 or more releases followed by recoveries |
|
|
Term
Dead Recoveries
R denotes
mij denotes
f denotes
|
|
Definition
R denotes sample of tagged animals
mij denotes released in period i and recovered in period j
f tag recovery rate (depends on which case)

Case 1: when hunters shoot and retrieve banded birds
|
|
|
Term
| Case: (1-S)(1-r); where (1-S) is probability of mortality and (1-r) is the probability of finding and reporting |
|
Definition
| Case 2. In many banding studies, marked animals are found dead and then reported |
|
|
Term

| Dead Recoveries Assumptions |
|
Definition
—Marking is representative of the population of interest
—No tag loss
—Tags are correctly recorded during banding and reporting
—Fates of tagged animals are independent
—*Homogeneity of survival and recovery probabilities for marked animals within parameter of interest
