WebAbout this book. This book introduces ecologists to the wonderful world of modern tools for data analysis, especially multivariate analysis. For biologists with relatively little prior knowledge of statistics, it introduces a modern, advanced approach to data analysis in an intuitive and accessible way. The book begins by reviewing some core ... WebIn terms of microbial ecology, analyzing the alpha diversity of amplicon sequencing data is known to be the common first step in assessing differences between microbial environments. Species richness, which the count of the number of species or operational taxonomic units (OTUs) present in an area, is the simplest measure of alpha diversity.
