Question

how could i estimate the carrying capacity for a population using the jolly seber method? Some of the variables i have obtained include population estimate, dilution rate, apparent survival, finite rate of growth and intristic growth rate. I also have the jolly seber work book, so how can i estimate the carrying capacity from these parameters.

Answer 1

Jolly seber method is used to extend the mark and recapture the open population and can be used to estimate carrying capacity. The open population is used to estimate carrying capacity after permitting the factors such as Birth, death, immigration, emigration, Dilution rate, Growth rate etc). The time intervals between samples need to be constant.

1. It is based on the fact that each and every individual having the same probability (a t) of being caught in the tth sample, and it doesnt matter that if it is marked or unmarked.

2. Probability is same for every marked individual (f t) which survive from the tth to the (t+1)st sample.

3. Marks do not get lost by the Individuals, and these marks are not overlooked at capture.

4. With relation to the intervals between sample the sampling time is considered negligible.
