  • Phylogeny and Phylogenetic Nomenclature of the Campanulidae Based on an Expanded Sample of Genes and Taxa
    Systematic Botany (2010), 35(2): pp. 425–441 © Copyright 2010 by the American Society of Plant Taxonomists Phylogeny and Phylogenetic Nomenclature of the Campanulidae based on an Expanded Sample of Genes and Taxa David C. Tank 1,2,3 and Michael J. Donoghue 1 1 Peabody Museum of Natural History & Department of Ecology & Evolutionary Biology, Yale University, P. O. Box 208106, New Haven, Connecticut 06520 U. S. A. 2 Department of Forest Resources & Stillinger Herbarium, College of Natural Resources, University of Idaho, P. O. Box 441133, Moscow, Idaho 83844-1133 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Previous attempts to resolve relationships among the primary lineages of Campanulidae (e.g. Apiales, Asterales, Dipsacales) have mostly been unconvincing, and the placement of a number of smaller groups (e.g. Bruniaceae, Columelliaceae, Escalloniaceae) remains uncertain. Here we build on a recent analysis of an incomplete data set that was assembled from the literature for a set of 50 campanulid taxa. To this data set we first added newly generated DNA sequence data for the same set of genes and taxa. Second, we sequenced three additional cpDNA coding regions (ca. 8,000 bp) for the same set of 50 campanulid taxa. Finally, we assembled the most comprehensive sample of cam- panulid diversity to date, including ca. 17,000 bp of cpDNA for 122 campanulid taxa and five outgroups. Simply filling in missing data in the 50-taxon data set (rendering it 94% complete) resulted in a topology that was similar to earlier studies, but with little additional resolution or confidence.

PhytoKeys 174: 13–45. https://doi.org/10.3897/phytokeys.174.59555 Abstract Lobelioideae, the largest subfamily within Campanulaceae, includes 33 genera and approximately1200 species. It is characterized by resupinate flowers with zygomorphic corollas and connate anthers and is widely distributed across the world. The systematics of Lobelioideae has been quite challenging over the years, with different scholars postulating varying theories. To outline major progress and highlight the ex- isting systematic problems in Lobelioideae, we conducted a literature review on this subfamily. Addition- ally, we conducted phylogenetic and biogeographic analyses for Lobelioideae using plastids and internal transcribed spacer regions.

  • ABSTRACT the First Through Fifth Instars of the Gypsy Moth Were Tested for Development to Adults on 326 Species of Dicotyledonous Plants in Laboratory Feeding Trials
    LABORATORY FEEDING TESTS ON THE DEVELOPMENT OF GYPSY MOTH LARVAE WITH REFERENCE TO PLANT TAXA AND ALLELOCHEMICALS JEFFREY C. MILLER and PAUL E. HANSON DEPARTMENT OF ENTOMOLOGY, OREGON STATE UNIVERSITY, CORVALLIS, OREGON 97331 ABSTRACT The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and Rosidae. Species of oak, maple, alder, madrone, eucalyptus, poplar, and sumac were highly suitable. Plants belonging to the Asteridae, Caryophyllidae, and Magnoliidae were mostly rejected. Foliage type, new or old, and instar influenced host plant suitability. Larvae of various instars were able to pupate after feeding on foliage of 147 plant species. Of these, 1.01 were accepted by first instars. Larvae from the first through fifth instar failed to molt on foliage of 151 species. Minor feeding occurred on 67 of these species. In general, larvae accepted new foliage on evergreen species more readily than old foliage. The results of these trials were combined with results from three previous studies to provide data on feeding responses of gypsy moth larvae on a total of 658 species, 286 genera, and 106 families of dicots. Allelochemic compositions of these plants were tabulated from available literature and compared with acceptance or rejection by gypsy moth. Plants accepted by gypsy moth generally contain tannins, but lack alkaloids, iridoid monoterpenes, sesquiterpenoids, diterpenoids, and glucosinolates. 2 PREFACE This research was funded through grants from USDA Forest Service cooperative agreement no.

Up to five independent colonizations have been proposed based on morphological differences among extant taxa. We present a molecular phylogeny showing that the Hawaiian lobeliads are the product of one immigration event; that they are the largest plant clade on any single oceanic island or archipelago; that their ancestor arrived roughly 13 Myr ago; and that this ancestor was most likely woody, wind-dispersed, bird-pollinated, and adapted to open habitats at mid-elevations. Invasion of closed tropical forests is associated with evolution of fleshy fruits. Limited dispersal of such fruits in wet-forest understoreys appears to have accelerated speciation and led to a series of parallel adaptive radiations in Cyanea, with most species restricted to single islands. Consistency of Cyanea diversity across all tall islands except Hawai`i suggests that diversification of Cyanea saturates in less than 1.5 Myr.
