Expected Phylogenetic Diversity and the Edge-Length Abundance Distribution We define sampled phylogenetic diversity to be the total branch length in a sampled tree, and we describe a sampled tree by a set of variables, gi, where i runs over each edge in the metacommunity tree and each gi can be either zero or one, corresponding to whether the edge also appears in the sampled tree. We define the...

Molecular evolutionary studies of eukaryotes have relied on a sparse collection of gene sequences that do not represent the full range of eukaryotic diversity in nature. Anaerobic microbes, particularly, have had little representation in phylogenetic studies. Such organisms are the least known of eukaryotes and probably are the most phylogenetically diverse. To provide fresh perspective on the ...

background and objectives: chlorophyceae are important constituents of marine phytoplankton. the taxonomy of chlorophyceae was traditionally based solely on morphological characteristics. in the present research project, genetic diversity was investigated to analyze five species of chlorophyceae from waters of the persian gulf. materials and methods:   a clone library of the ribosomal small sub...
