摘要:
The technique of estimating wildlife population size and density using the belt or line—transect sampling method has been used in many past projects, such as the estimation of density of waterfowl nesting sites in marshes, and is being used currently in such areas as the assessment of Pacific porpoise stocks in regions of tuna fishing activity. A mathematical framework for line—transect methodology has only emerged in the last 5 yr. In the present article, we extend this mathematical framework to a line—transect estimator based upon a log—linear model approach.

摘要:
A Monte Carlo technique was used to produce sets of samples from a series of artificial 2—species communities. The Fagerrecurrent group index was calculated for these samples. The effects of sample numbers were assessed by comparing the sample indices to size—corrected population index values. A small negative bias was noted for indices calculated from the smaller sample sets, particularly in those communities where the species were rare. The index appears to give conservative estimates of affinity when only a small number of samples are taken.
