Adaptive Line Transect Sampling

Biometrics, 2002
Adaptive line transect sampling offers the potential of improved population density estimation efficiency over conventional line transect sampling when populations are spatially clustered. In adaptive sampling, survey effort is increased when areas of high animal density are located, thereby increasing the number of observations.

Line Transect Methods for Plant Surveys

Biometrics, 2007
SummaryInterest in surveys for monitoring plant abundance is increasing, due in part to the need to quantify the rate of loss of biodiversity. Line transect sampling offers an efficient way to monitor many species. However, the method does not work well in some circumstances, for example on small survey plots, when the plant species has a strongly ...

Incorporating Covariates into Standard Line Transect Analyses

Biometrics, 2003
Summary. An implicit assumption of standard line transect methodology is that detection probabilities depend solely on the perpendicular distance of detected objects to the transect line. Heterogeneity in detection probabilities is commonly minimized using stratification, but this may be precluded by small sample sizes. We develop a general methodology

A Remark on the Line Transect Method

Biometrical Journal, 1982
AbstractThis paper gives a re‐formulation of a model for the line transect method in terms of the theory of stationary point processes. The well‐known formulae for this method are shown to be valid also under very general assumptions.
