Chaos,onsistently fits insect data. Unfortunately, there are at least 16 models giving rise to the negative binomial, many of which could be given a biological interpretation (Boswell and Patii, 1970). Therefore, the fact that a particular probability distribution fits does not necessarily provide insight into the underlying biological forces.

Sequentially Testing Three Hypotheses,ately the mid-crown height of the trees. In the study reported by Morris (1954), very tall trees for which the mid-crown could not be reached with pole pruners were felled and sample branches selected as follows: one branch from the apical quarter of the crown, one from the second quarter, one-half

Capture-Recapture: Closed Populations,the animal species whose mobility require alternative sampling methods. Difficulties also arise if the population is sparse. Either very large sampling units or a large number of them is required to estimate population density with an acceptable level of precision.

,Capture—Recapture: Open Populations,parameters can be estimated with less data. However, it is not always possible to design a study so that the closed population assumption holds even approximately. In these cases, the open population models are needed. The seminal work on open population models was conducted independently by Jolly (

Life-Stage Analysis, is density dependent. Interest may be focused on the stability of the population and factors affecting that stability. We refer to the statistical approach to answering these questions as life-stage analysis. Caughley (1977a), Southwood (1978) and Pedigo and Zeiss (1996) discuss life-table construc
