Download E-books Advanced Distance Sampling: Estimating Abundance of Biological Populations PDF

By J.L. Laake

This complex textual content specializes in the makes use of of distance sampling to estimate the density and abundance of organic populations. It addresses new methodologies, new applied sciences and up to date advancements in statistical thought and is the persist with up significant other to Introduction to Distance Sampling (OUP, 2001).
