| Summary : Normalized Stochasticity Ratio
|
Description :
To estimate ecological stochasticity in community assembly.
Understanding the community assembly mechanisms controlling
biodiversity patterns is a central issue in ecology. Although it is
generally accepted that both deterministic and stochastic processes
play important roles in community assembly, quantifying their relative
importance is challenging. The new index, normalized stochasticity
ratio (NST), is to estimate ecological stochasticity, i.e. relative
importance of stochastic processes, in community assembly. With
functions in this package, NST can be calculated based on different
similarity metrics and/or different null model algorithms, as well as
some previous indexes, e.g. previous Stochasticity Ratio (ST), Standard
Effect Size (SES), modified Raup-Crick metrics (RC). Functions for
permutational test and bootstrapping analysis are also included.
Previous ST is published by Zhou et al (2014)
< doi:10.1073/pnas.1324044111>. NST is modified from ST by considering
two alternative situations and normalizing the index to range from 0 to
1 (Ning et al 2019) < doi:10.1073/pnas.1904623116>. A modified version,
MST, is a special case of NST, used in some recent or upcoming
publications, e.g. Liang et al (2020)
< doi:10.1016/j.soilbio.2020.108023>. SES is calculated as described in
Kraft et al (2011) < doi:10.1126/science.1208584>. RC is calculated as
reported by Chase et al (2011) < doi:10.1890/ES10-00117.1> and Stegen et
al (2013) < doi:10.1038/ismej.2013.93>. Version 3 added NST based on
phylogenetic beta diversity, used by Ning et al (2020)
< doi:10.1038/s41467-020-18560-z>.
