For those of whom I am unable to personally thank here, know that I deeply appreciate your support. First and foremost, I want to thank my chair Michael Glassow for his patience, enthusiasm, and encouragement during all aspects of this daunting project. I am also truly grateful to have had the opportunity to know, learn from, and work with my other committee members, Mike Jochim, Amber VanDerwarker, and Lynn Gamble. I cherish my various field experiences with them all on the Channel Islands and especially in southern Germany with Mike Jochim, whose worldly perspective I value deeply. I also thank Terry Jones, who provided me many undergraduate opportunities in California archaeology and encouraged me to attend a field school on San Clemente Island with Mark Raab and Andy Yatsko, an experience that left me captivated with the islands and their history.
  • Outline of Angiosperm Phylogeny

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

Department nf Botany The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 26 March 1980 ABSTRACT Seven species are recognized in Arnica subgenus Austromontana and two species in a new subgenus Calarnica based on a critical review and conserva• tive revision of the species. Chromosome numbers are given for 91 populations representing all species, including the first reports for Arnica nevadensis. Results of apomixis, vegetative reproduction, breeding studies, and artifi• cial hybridizations are given. Interrelationships of insect pollinators, leaf miners, achene feeders, and floret feeders are presented. Arnica cordifolia, the ancestral species consists largely of tetraploid populations, which are either autonomous or pseudogamous apomicts, and to a lesser degree diploid, triploid, pentaploid, and hexaploid populations.

    A Phylogeny of Legumes (Leguminosae) Based on Analysis of the Plastid Matk Gene Resolves Many Well-Supported Subclades Within the Family1

    American Journal of Botany 91(11): 1846±1862. 2004. A PHYLOGENY OF LEGUMES (LEGUMINOSAE) BASED ON ANALYSIS OF THE PLASTID MATK GENE RESOLVES MANY WELL-SUPPORTED SUBCLADES WITHIN THE FAMILY1 MARTIN F. W OJCIECHOWSKI,2,5 MATT LAVIN,3 AND MICHAEL J. SANDERSON4 2School of Life Sciences, Arizona State University, Tempe, Arizona 85287-4501 USA; 3Department of Plant Sciences, Montana State University, Bozeman, Montana 59717 USA; and 4Section of Evolution and Ecology, University of California, Davis, California 95616 USA Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly of subfamily Papilionoideae and at least seven major subclades are well-supported by bootstrap and Bayesian credibility values. These subclades are informally recognized as the Cladrastis clade, genistoid sensu lato, dalbergioid sensu lato, mirbelioid, millettioid, and robinioid clades, and the inverted-repeat-lacking clade (IRLC). The genistoid clade is expanded to include genera such as Poecilanthe, Cyclolobium, Bowdichia, and Diplotropis and thus contains the vast majority of papilionoids known to produce quinolizidine alkaloids. The dalbergioid clade is expanded to include the tribe Amorpheae. The mirbelioids include the tribes Bossiaeeae and Mirbelieae, with Hypocalypteae as its sister group. The millettioids comprise two major subclades that roughly correspond to the tribes Millettieae and Phaseoleae and represent the only major papilionoid clade marked by a macromorphological apomorphy, pseu- doracemose in¯orescences.

    Classification of the Vegetation Alliances and Associations of Sonoma County, California

    Classification of the Vegetation Alliances and Associations of Sonoma County, California Volume 1 of 2 – Introduction, Methods, and Results Prepared by: California Department of Fish and Wildlife Vegetation Classification and Mapping Program California Native Plant Society Vegetation Program For: The Sonoma County Agricultural Preservation and Open Space District The Sonoma County Water Agency Authors: Anne Klein, Todd Keeler-Wolf, and Julie Evens December 2015 ABSTRACT This report describes 118 alliances and 212 associations that are found in Sonoma County, California, comprising the most comprehensive local vegetation classification to date. The vegetation types were defined using a standardized classification approach consistent with the Survey of California Vegetation (SCV) and the United States National Vegetation Classification (USNVC) system. This floristic classification is the basis for an integrated, countywide vegetation map that the Sonoma County Vegetation Mapping and Lidar Program expects to complete in 2017. Ecologists with the California Department of Fish and Wildlife and the California Native Plant Society analyzed species data from 1149 field surveys collected in Sonoma County between 2001 and 2014. The data include 851 surveys collected in 2013 and 2014 through funding provided specifically for this classification effort. An additional 283 surveys that were conducted in adjacent counties are included in the analysis to provide a broader, regional understanding. A total of 34 tree-overstory, 28 shrubland, and 56 herbaceous alliances are described, with 69 tree-overstory, 51 shrubland, and 92 herbaceous associations. This report is divided into two volumes. Volume 1 (this volume) is composed of the project introduction, methods, and results. It includes a floristic key to all vegetation types, a table showing the full local classification nested within the USNVC hierarchy, and a crosswalk showing the relationship between this and other classification systems.
