The examination will be conducted in English. Abstract Vinnersten, A. 2003. Tracing History. Phylogenetic, Taxonomic and Biogeographic Research in the Colchicum Family. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911. 33 pp. Uppsala. ISBN 91-554-5814-9 This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. The molecular analysis based on three plastid regions—the rps16 intron, the atpB- rbcL intergenic spacer, and the trnL-F region—reveal the intrafamilial classification to be in need of revision. The two tribes Iphigenieae and Uvularieae are demonstrated to be paraphyletic. The well-known genus Colchicum is shown to be nested within Androcymbium, Onixotis constitutes a grade between Neodregea and Wurmbea, and Gloriosa is intermixed with species of Littonia. Two new tribes are described, Burchardieae and Tripladenieae, and the two tribes Colchiceae and Uvularieae are emended, leaving four tribes in the family. At generic level new combinations are made in Wurmbea and Gloriosa in order to render them monophyletic. The genus Androcymbium is paraphyletic in relation to Colchicum and the latter genus is therefore expanded.

    Reptiles in and Around the House Identification and Distribution Reptiles Inhabit Every Environment in Australia

    Reptiles in and around the house Identification and Distribution Reptiles inhabit every environment in Australia. Common reptiles found in Western Australian backyards include: Tiger snakes Notechis scutatus occur in southwest WA, and are often seen near water, including rivers, dams, drains and wetlands. Unlike most other Australian elapids, tiger snakes climb well. They can range from grey, olive, brown to black in colour and often have yellow and black cross-bands, but not all have this pattern. Venomous Dugite. Photo: R. Lloyd/Fauna Track Dugites Pseudonaja affinis occur in southwest WA and Gwarda Pseudonaja nuchalis occur from Perth northwards. They live in a wide variety of habitats including coastal dunes, heathlands, shrublands, woodlands and forests. They are long and slender, with relatively large scales that have a semi-glossy appearance. They can range from brown, olive to grey in colour, and can have irregular black/dark grey spotting, but patterning varies. Venomous Mulga snakes Pseudechis australis occur in a wide variety of habitats, northwards from Perth and Narrogin. They are quite robust, with a broad, deep head and bulbous cheeks. They can range from pale brown, dark olive to reddish-brown in colour, and darker snakes often have two-toned scales with a lighter colour that contrasts with the darker colour to produce a reticulated effect. The belly is cream to salmon-coloured. Venomous There are two subspecies of carpet pythons found in a large variety of habitats in WA: Morelia spilota imbricata occurs in the southwest and Morelia spilota variegata occurs in the Kimberley. They are 1-4m in length, tend to be pale to dark brown with black blotches that sometimes have a Carpet python.

  • 10 Seed Release and Dispersal Mechanisms

    10 Seed Release and Dispersal Mechanisms

    10 Seed Release and Dispersal Mechanisms For seedling recruitment to occur seeds need to be dispersed into an environment that promotes germination and seedling survival. Dispersal consists of two phases. Primary dispersal is defined as the initial transport of seeds or seed-bearing fruits (collectively seeds and fruits are called diaspores) to the ground or water body, or for aerial parasites, a host branch. Secondary dispersal relates to any subsequent movement to the seed’s final resting place. Primary dispersal may be active (e.g. seeds released explosively from the fruit, e.g. dehiscence (opening) of Hardenbergia pods), passive (e.g. seeds fall out when the capsules of Eucalyptus open), or require a vector to aid in seed removal (e.g. wind uplift of winged seeds of Hakea or winged fruits of Nuytsia; Amyema berries consumed by mistletoe birds). Secondary dispersal involves either a biotic (e.g. ants) or environmental (e.g. wind, water) vector, and it is usually a different mechanism than that involved in primary dispersal. While primary dispersal is usually only for a few metres, secondary dispersal may cover several kilometres, and sometimes thousands for tiny seeds. This chapter covers some of the dispersal mechanisms exhibited by the SouthWest flora following their release. Terminology used to describe seed dispersal mechanisms is provided in Table 10.1. Table 10.1: Seed dispersal terminology. Term Definition Anemochory Wind dispersed Chamaechory Dispersal by rolling along the ground (wind assisted) Zoochory Animal dispersed (general) Myrmecochory Ant dispersed Ornithochory Bird dispersed Mammalochory Mammal dispersed Hydrochory Water dispersed Barochory Unassisted (gravity causes seeds to drop to the ground) Autochory Dispersal assisted by the actions of the parent plant (e.g.

    GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

    Vicariance, Climate Change, Anatomy and Phylogeny of Restionaceae

    Botanical Journal of the Linnean Society (2000), 134: 159–177. With 12 figures doi:10.1006/bojl.2000.0368, available online at http://www.idealibrary.com on Under the microscope: plant anatomy and systematics. Edited by P. J. Rudall and P. Gasson Vicariance, climate change, anatomy and phylogeny of Restionaceae H. P. LINDER FLS Bolus Herbarium, University of Cape Town, Rondebosch 7701, South Africa Cutler suggested almost 30 years ago that there was convergent evolution between African and Australian Restionaceae in the distinctive culm anatomical features of Restionaceae. This was based on his interpretation of the homologies of the anatomical features, and these are here tested against a ‘supertree’ phylogeny, based on three separate phylogenies. The first is based on morphology and includes all genera; the other two are based on molecular sequences from the chloroplast genome; one covers the African genera, and the other the Australian genera. This analysis corroborates Cutler’s interpretation of convergent evolution between African and Australian Restionaceae. However, it indicates that for the Australian genera, the evolutionary pathway of the culm anatomy is much more complex than originally thought. In the most likely scenario, the ancestral Restionaceae have protective cells derived from the chlorenchyma. These persist in African Restionaceae, but are soon lost in Australian Restionaceae. Pillar cells and sclerenchyma ribs evolve early in the diversification of Australian Restionaceae, but are secondarily lost numerous times. In some of the reduction cases, the result is a very simple culm anatomy, which Cutler had interpreted as a primitively simple culm type, while in other cases it appears as if the functions of the ribs and pillars may have been taken over by a new structure, protective cells developed from epidermal, rather than chlorenchyma, cells.
