The concept of similarity, or a sense of 'sameness' among things, is pivotal to theories in the
cognitive sciences and beyond. Similarity, however, is a difficult thing to measure …

Nonmetric multidimensional scaling (NMDS) is a powerful statistical tool which enables
complex multivariate data sets to be visualized in a reduced number of dimensions. Users …

In this work, we compare the resolution of V2-V3 and V3-V4 16S rRNA regions for the
purposes of estimating microbial community diversity using paired-end Illumina MiSeq …

Background Agricultural food production is at the base of food and fodder, with fertilization
having fundamentally and continuously increased crop yield over the last decades. The …

Aim To examine the contribution of large‐diameter trees to biomass, stand structure, and
species richness across forest biomes. Location Global. Time period Early 21st century …

The book describes and discusses the numerical methods which are successfully being
used for analysing ecological data, using a clear and comprehensive approach. These …

In the early 1980s, a strategy for graphical representation of multivariate (multi‐species)
abundance data was introduced into marine ecology by, among others, Field, et al.(1982). A …

The method of choice for multivariate representation of community structure is often non-
metric multi-dimensional scaling (MDS). This has great flexibility in accomn~ odating …

A flexible method is needed for constrained ordination on the basis of any distance or
dissimilarity measure, which will display a cloud of multivariate points by reference to a …

Publisher Summary The theory of gradient analysis is presented in this chapter, in which the
heuristic techniques are integrated with regression, calibration, ordination and constrained …
