Research Description

Mishler's research interests can be grouped into two main areas: empirical studies of ecology, phylogeny, systematics, and development of mosses, and the theoretical basis of systematic and evolutionary biology.

Empirical studies include: (1) the phylogenetic relationships of the major groups of bryophytes (including mosses) and other land plants, using morphological, developmental, and ultrastructural characters as well as chloroplast DNA sequence data; (2) the development of moss peristomes in relation to evolution of the group; and (3) biosystematic studies of the haplolepideous mosses, including the tropical family Calymperaceae and the diverse temperate genus Tortula (Syntrichia), which involve transplant and ecological studies in the field, comparative physiological measurements and culture experiments in the lab, and morphological studies in the herbarium; (4) the reproductive biology of bryophytes, especially dryland mosses; and (5) the bryophyte floras of California, Moorea (in the Society Islands of the South Pacific), and Australia.

Theoretical studies include investigations of the nature of species, rank-free classification, methods for phylogenetic reconstruction (with an emphasis on cladistic analysis of molecular and genomic data), the relationship between development and evolution, phyloinformatics (comparative genomics, databasing, and visualization of phylogenetic trees), and biodiversity informatics (digitization of biological collections and integration with taxonomic and ecological data). His lab applies methods ranging from microscopy through growth experiments, DNA sequencing, and comparative genomics.
