    Thesis (Ph.D.) University of Alaska Fairbanks, 1987Four sections of the genus Primula are represented in northern North America: Aleuritia, Armerina, Crystallophlomis, and Cuneifolia. In this dissertation I discuss anatomical, morphological, cytological, ecological, and reproductive characters for thirteen species, and demonstrate coherence of sectional groups through cluster analysis and ordination. In Primula, distyly and homostyly play critical roles in systematics and biogeography. It is generally assumed that distylous individuals are almost completely outcrossed, and homostyles are capable of selfing. In the taxa examined here, distyly exists at the diploid and tetraploid levels while homostyly is seen in both diploids and higher polyploids. I suggest that distyly breaks down with selection for reproductive assurance in environments where pollinators are unreliable, or following hybridization in conjunction with polyploidy. While most northern Primula species are homostylous, several examples of distylous taxa demonstrate that this can be a successful breeding system in higher latitudes. In homostyles, self-compatibility and the proximity of reproductive organs assures a high degree of selfing; however, most northern homostylous taxa also exhibit attributes which suggest facultative outcrossing is common. In North America, evolution in Primula has been strongly influenced by Quaternary events leading to isolation, migration, and secondary contact of gene pools, in association with the breakdown of distyly to homostyly. The success of homostylous taxa is at least partially due to their ability to self-fertilize coupled with the availability of areas to colonize when Pleistocene ice retreated. The phytogeographic affinities, cytology, and reproductive shifts of Primula make it a useful model for processes occurring in the Alaskan flora. The steppes and mountains of Asia have been important source areas, and migration has taken place along mountains, rivers, island arcs, and coastlines. Speciation in the genus has been aided by hybridization, polyploidy, and reproductive diversity

    A taxonomic and phylogeographic study of the Botrychium lunaria complex

    Get PDF
    This dissertation documents an analysis of genetic diversity in the Botrychium lunaria complex using starch gel enzyme electrophoresis and statistical analysis of genetic relationships. The study resulted in identifying the genetic variation within and between the entities comprising the complex and revealed their geographic distribution. These results provided a basis for inferring what entities comprise the complex and how the entities may be recognized taxonomically. This study also examines the biogeography of the B. lunaria complex. I used the results of enzyme electrophoresis studies, statistical analysis and Geographical Information Systems (GIS) mapping to investigate the complex\u27s origins, the relationships between its entities, how the entities arose and their patterns of geographic distribution. Studies revealed considerable genetic diversity within the B. lunaria complex as well as distinct geographic patterns to the complex\u27s genetic diversity. In addition, I determined how the genetic entities should be recognized taxonomically and at which taxonomic levels they should be recognized. Geographic distribution of the members of the B. lunaria complex reflects their phylogenetic relationships. Their genetic composition, migration patterns and divergence times reveal genetic isolation that can probably be attributed to Quaternary glacial-interglacial cycles. The present distribution of members of the B. lunaria complex can also be explained, in part, by long distance dispersal via spores. Divergences between taxa occurred during different glacial periods. Distributions of taxa also indicate post-glacial spread of taxa and genotypes. Beringia, the landmass connecting eastern Siberia and Alaska, is a center of moonwort diversity as well as providing a colonization route between Eurasia and North America
