Spatial distribution, sampling efficiency and Taylor's power law
2018
TAYLOR, R. A. J.
1. A relationship between sampling efficiency and Taylor's power law (TPL) is derived and illustrated with data from gypsy moth samples taken in Pennsylvania. 2. It is shown that attractant traps such as pheromone and light traps may exhibit density‐dependent sampling efficiency which can influence the parameters of TPL. 3. Comparison of the light trap and pheromone trap sample data with those of a standardised suction trap enables the attractant traps to be standardised. 4. Rescaling male moth catches per trap to number per unit volume increases the slope, intercept and correlation coefficient while stretching the pattern of data points. 5. Density‐dependent sampling efficiency of attractant traps shows how TPL is sensitive to spatial aggregation behaviour as well as other life‐history variables.
