摘要: A composite approach to point transect sampling is adopted in which the properties of abundance estimator stem from scheme performed select points on study area as well modelled probabilities detection. consistent and asymptotically normal derived under some assumptions about detection function, while a multivariate generalization this result provided multi-species surveys estimate species vector. Jackknife estimators diversity indices are also functions estimators. An application considered for comparing ecological avian communities short rotation forestry versus traditional crops.
