T.  aStudies in the analysis of data from Australia tidal forest ('Mangroves'). II. The use of an asymmetric monothetic divisive classificatory program.  c1980  aAn algorithm (ASYM) is defined which implements a monothetic divisive classification of presence/absence data; it is based on the Jaccard measure and is consequently asym- metric, in that it ignores double-zero matches. It is insensitive to group size but sensitive to floristic heterogeneity. An extensive set of Australian tidal forest data is processed both by ASYM and by the symmetric information-statistic divisive program DIVINE. It is concluded that the two systems are complementary in that they reveal somewhat different aspects of the data-structure; but that if only program were to be used, ASYM would be ecological preferable.  aAustralia  aAnálise  aAnalysis  aAsymetric monothetic divisive  aClassificatory program  aFloresta relativo a mare  aMangroves  aPrograma classificatorio  aTidal forests1 aBUNT, J.
