	Systematics of bryophytes, particularly Pottiaceae Phylogenetic theory (evaluating the reliability of reconstruction) Flora of North America (Lead Editor, Vols. 27-29, the bryophyte volumes) Websites Bryophyte Flora of North America Res Botanica Research Emphases With the revolution in computerized data management and information processing, certain new computer-mediated methods have been touted as "paradigm changes": e.g. complexity theory, chaos theory, fuzzy logic, and phylogenetic reconstruction. As to the last, I consider it a major incremental change but certainly not a revolution given a general lack of reliably supported "bold conjectures," and have directed efforts to counter this in five areas: 1. Continued work in traditional taxonomy in the face of a major new emphasis in the field on phylogenetic work: (A) Taxonomic treatments of Pottiaceae for FNA. (B) Manage and promote completion of the three bryophyte volumes for the FNA. 2. Evaluate the ways phylogenetic analysis is considered (by its practitioners) acceptable as a basis of: (A) classification and (B) reconstruction of evolutionary relationships. This includes examining the reliability of standard statistical methods (e.g., bootstrap and decay index), and the introduction of new measures based on nearest neighbor interchange and exact binomial tests. Paraphyly in my opinion is acceptable because monophyly simply reflects an inherent limitation in the method of phylogenetic analysis, namely that reconstruction of genealogies cannot provide acceptable species definitions any other way. 3. Promotion of appreciation for the the ecological species concept as more representative of the basic unit of taxonomy required by biodiversity studies. The ideal species concept should be comparative evolutionary ecology. Selected Publications The Pottiaceae s.str. as an evolutionary Lazarus taxon. J. Hattori Bot. Lab. 100: 581--602.  2006. Reprint.
