Species-Site Compositional Matrix Comparison Methods
Pp. 33-45 (13)
Matrix comparison is an important element in community ecology because
the distribution of different species over different areas is usually compiled in a form of
a species-site matrix. Thus, if we have different species-site matrices (different species
groups in the same sites or the same species assemblage in different non-spatially
overlapped regions), we may want to know whether the resultant species-site matrices
present similarities. In other words, we may want to compare the distributional
congruence of the same set of species across different non-spatially overlapped regions
or the distributional congruence of different groups of species in the same set of sites
for a region. Thus, statistical methods for matrix comparison could help address these
ecological questions. In this chapter, I will present the major statistical methods for
conducting matrix similarity comparison. I will use the distribution of bird and mammal
species in Hainan Island of China as the case study and example to demonstrate some of
the matrix comparison methods introduced in the chapter.
