Molecular Phylogenetics of Mosses and Relatives
MOLECULAR PHYLOGENETICS OF MOSSES AND RELATIVES! by! Ying Chang! ! ! A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF ! DOCTOR OF PHILOSOPHY! in! The Faculty of Graduate Studies! (Botany)! ! ! THE UNIVERSITY OF BRITISH COLUMBIA! (Vancouver)! July 2011! © Ying Chang, 2011 ! ABSTRACT! Substantial ambiguities still remain concerning the broad backbone of moss phylogeny. I surveyed 17 slowly evolving plastid genes from representative taxa to reconstruct phylogenetic relationships among the major lineages of mosses in the overall context of land-plant phylogeny. I first designed 78 bryophyte-specific primers and demonstrated that they permit straightforward amplification and sequencing of 14 core genes across a broad range of bryophytes (three of the 17 genes required more effort). In combination, these genes can generate sturdy and well- resolved phylogenetic inferences of higher-order moss phylogeny, with little evidence of conflict among different data partitions or analyses. Liverworts are strongly supported as the sister group of the remaining land plants, and hornworts as sister to vascular plants. Within mosses, besides confirming some previously published findings based on other markers, my results substantially improve support for major branching patterns that were ambiguous before. The monogeneric classes Takakiopsida and Sphagnopsida likely represent the first and second split within moss phylogeny, respectively. However, this result is shown to be sensitive to the strategy used to estimate DNA substitution model parameter values and to different data partitioning methods. Regarding the placement of remaining nonperistomate lineages, the [[[Andreaeobryopsida, Andreaeopsida], Oedipodiopsida], peristomate mosses] arrangement receives moderate to strong support. Among peristomate mosses, relationships among Polytrichopsida, Tetraphidopsida and Bryopsida remain unclear, as do the earliest splits within sublcass Bryidae. -

First found in Florida in Miami in 1968, this invasive aphid can now be found anywhere in Florida Description where the genus Podocarpus is grown (Brown and Mannion The podocarpus aphid is easily distinguishable from other 2014). aphids by its bluish-purple color (Hidalgo et al. 2015) (Figure 1). The body of the adult aphid is 1.3 mm in length and flattened dorsoventrally (Takahashi 1920; Foottit et al. 2012). The antennae are six segmented and shorter than the length of the body (Russell 1982). The female aphids can be winged or wingless. Wingless females are oval and have a white wax dusting while winged females are similar in appearance, with a slight difference in antennal and leg structure (Hidalgo et al. 2015). The winged females will often have small scent glands, called pseudosensoria, present on their hind tibiae (the first segment of their hind legs) (Russell 1982). -

Johnsonby Benjamin L. Turner and withLucas contributions A. Cernusak by Stanley A. Ahler, Herbert Haas, and Georges Bonani SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institu- tions throughout the world. Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affilia- tion with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. -

In this preliminary experiment seeds of juniper from four stands in different elevations (1900, 2100, 2200, 2250 m) were subjected to two pre-treatments with different duration period: warm stratification for three-months followed by 45 days warm stratification followed by 45 days cold stratification, and six months with 90 days warm followed by 90 days cold stratification. In comparison to the other three stands, the stand 2100 above sea level had more vigorous trees from which the seeds were collected. After stratification, seed samples were subjected to a standard germination test according to ISTA regulations. Juniper seeds originating from the Kalamoun mountains showed with 92.5% a high percentage of empty seeds. The better quality of seeds with less empty seeds (87%) were found in the stand which included the more vigorous juniper trees in 2100 m above sea level. Germination of seeds was significantly dependant on the duration period of the warm and cold stratification. -
