5.2.4.5 Beta-diversity analysis Beta-diversity of microbial communities illustrates the relative differences in species composition between habitats (Pane et al., 2020). Alpha diversity is only concerned about single sample analysis. Therefore despite of similar alpha diversity value, two different sample...
We calculated and compared Rao's Q and Shannon indices at different spatial resolutions (0.5, 5, and 30m) and scales (window sizes) by using imageries from Pl茅iades 1A, RapidEye, and Landsat-8 acquired in April 2013, the pre-monsoon season. Rao's Q index explained diversity more ...
Aim This paper presents the statistical bases for temporal beta‐diversity analysis, a method to study changes in community composition through time from repeated surveys at several sites. Surveys of that type are presently done by ecologists around the world. A temporal beta‐diversity Index (TBI)...

In studies of spatial or temporal beta diversity, community composition data, often containing many zeros, must be transformed in some way before they are analysed by multivariate methods of data analysis. Data are transformed to reduce the skewness of species distributions and make dissimilarities dou...

Moreover, total beta can be broken up into within- and among-group components by manova, into orthogonal axes by ordination, into spatial scales by eigenfunction analysis or among explanatory data sets by variation partitioning. 展开 关键词: Beta diversity community composition data community ecology...
