The analyses, including type species of all genera in Koeleriinae (Acrospelion, Avellinia, Cinnagrostis, Gaudinia, Koeleria, Leptophyllochloa, Limnodea, Peyritschia, Rostraria, Sphenopholis, Trisetaria, Trisetopsis, Trisetum), along with three outgroups, confirm previous indications of extensive polyphyly of Trisetum. We focus on the monophyletic Trisetum sect. Sibirica cladethatweinterprethereasadistinctgenus,Sibirotrisetum gen. nov. We include adescriptionofSibirotrisetum with the following seven new combinations: Sibirotrisetum aeneum, S. bifidum, S. henryi, S. scitulum, S. sibiricum, S. sibiricum subsp. litorale,andS. turcicum; and a single new combination in Acrospelion: A. distichophyllum. Trisetum s.s. is limited to one, two or three species, pending further study. Key words: Acrospelion, Aveneae, grasses, molecular systematics, Poeae, Sibirotrisetum, taxonomy, Trisetum.

S. Hitchcock, revised by Agnes Chase (1951). iii PREFACE The first part of our Annotated Checklist, covering the 2001 species of Ferns, Fern Allies, Gymnosperms, and Dicotyledons native or naturalized in the Washington-Baltimore Area, was published in March 2000. Part II covers the Monocotyledons and completes the preliminary edition of the Checklist, which we hope will prove useful not only in itself but also as a first step toward a new manual for the identification of the Area’s flora. Such a manual is needed to replace the long- outdated and out-of-print Flora of the District of Columbia and Vicinity of Hitchcock and Standley, published in 1919. In the preparation of this part, as with Part I, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. As with the first part, we are distributing this second part in preliminary form, so that it can be used, criticized, and updated while the two parts are being readied for publication as a single volume.

Severtzov Institute of Problems of Evolution and Ecology of the Russian Academy of Sciences, Leninski Prospect 33, 119017 Moscow, Russia Abstract: Alpine grasslands in the Southern Carpathian Mts, Romania, harbour an extraordinarily high diversity of plants and invertebrates, including Carpathic endemics. In the past decades, intensive sheep grazing has caused a dramatic de- crease in biodiversity and even led to eroded soils at many places in the Carpathians. Because of limited food resources, sheep are increasingly forced to graze on steep slopes, which were formerly not grazed by livestock and are considered as local biodiversity hotspots. We examined species richness, abundance and number of endemic vascular plants and terres- trial gastropods on steep slopes that were either grazed by sheep or ungrazed by livestock in two areas of the Southern Carpathians. On calcareous soils in the Bucegi Mts, a total of 177 vascular plant and 19 gastropod species were recorded. Twelve plant species (6.8%) and three gastropod species (15.8%) were endemic to the Carpathians.

  • Arctic National Wildlife Refuge Volume 2
    Appendix F Species List Appendix F: Species List F. Species List F.1 Lists The following list and three tables denote the bird, mammal, fish, and plant species known to occur in Arctic National Wildlife Refuge (Arctic Refuge, Refuge). F.1.1 Birds of Arctic Refuge A total of 201 bird species have been recorded on Arctic Refuge. This list describes their status and abundance. Many birds migrate outside of the Refuge in the winter, so unless otherwise noted, the information is for spring, summer, or fall. Bird names and taxonomic classification follow American Ornithologists' Union (1998). F.1.1.1 Definitions of classifications used Regions of the Refuge . Coastal Plain – The area between the coast and the Brooks Range. This area is sometimes split into coastal areas (lagoons, barrier islands, and Beaufort Sea) and inland areas (uplands near the foothills of the Brooks Range). Brooks Range – The mountains, valleys, and foothills north and south of the Continental Divide. South Side – The foothills, taiga, and boreal forest south of the Brooks Range. Status . Permanent Resident – Present throughout the year and breeds in the area. Summer Resident – Only present from May to September. Migrant – Travels through on the way to wintering or breeding areas. Breeder – Documented as a breeding species. Visitor – Present as a non-breeding species. * – Not documented. Abundance . Abundant – Very numerous in suitable habitats. Common – Very likely to be seen or heard in suitable habitats. Fairly Common – Numerous but not always present in suitable habitats. Uncommon – Occurs regularly but not always observed because of lower abundance or secretive behaviors.

    GLOBAL RELATIONSHIPS BETWEEN PLANT FUNCTIONAL TRAITS AND ENVIRONMENT IN GRASSLANDS EMMA JARDINE A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy The University of Sheffield Department of Animal and Plant Sciences Submission Date July 2017 ACKNOWLEDGMENTS First of all I am enormously thankful to Colin Osborne and Gavin Thomas for giving me the opportunity to undertake the research presented in this thesis. I really appreciate all their invaluable support, guidance and advice. They have helped me to grow in knowledge, skills and confidence and for this I am extremely grateful. I would like to thank the students and post docs in both the Osborne and Christin lab groups for their help, presentations and cake baking. In particular Marjorie Lundgren for teaching me to use the Licor, for insightful discussions and general support. Also Kimberly Simpson for all her firey contributions and Ruth Wade for her moral support and employment. Thanks goes to Dave Simpson, Maria Varontsova and Martin Xanthos for allowing me to work in the herbarium at the Royal Botanic Gardens Kew, for letting me destructively harvest from the specimens and taking me on a worldwide tour of grasses. I would also like to thank Caroline Lehman for her map, her useful comments and advice and also Elisabeth Forrestel and Gareth Hempson for their contributions. I would like to thank Brad Ripley for all of his help and time whilst I was in South Africa. Karmi Du Plessis and her family and Lavinia Perumal for their South African friendliness, warmth and generosity and also Sean Devonport for sharing all the much needed teas and dub.

What animals achieve by active movement plants must accomplish by adaptive form. The feather-like stigmas of a grass flower filter the air for floating pollen; a dandelion with tiny paratroopers establishes a new beachhead; and a mountain mahogany seed drills itself by hygroscopic movement through the leaf litter on an arid hillside. These examples illustrate plant-life's shrewd mastery of the environment. Plants are highly sensitive to their surroundings. From their small fortresses they must endure the coldest temperatures, the strongest winds, the longest drought, fire, and the attacks of predators.

  • High-Latitude Yukon Boreal-Cordilleran Grassland Plant Communities Wayne L Strong1
    ARCTIC VOL. 68, NO. 1 (MARCH 2015) P. 69 – 78 http://dx.doi.org/10.14430/arctic4453 High-Latitude Yukon Boreal-Cordilleran Grassland Plant Communities Wayne L Strong1 (Received 13 January 2014; accepted in revised form 10 June 2014) ABSTRACT. High-latitude (61.9˚ – 62.8˚ N) graminoid plant communities located near the northern limit of boreal forest occurrence in the Carmacks – Pelly Crossing area of Yukon were sampled and classified, and four sociations were recognized: Calamagrostis purpurascens (purple reedgrass), Hesperostipa comata (needle-and-thread grass), Poa glauca – Artemisia frigida (glaucous bluegrass – pasture sagewort), and Pseudoroegneria spicata – Artemisia frigida (bluebunch wheatgrass – pasture sagewort). These plant communities occurred primarily on south-southwest slopes (180˚ – 230˚) with 45% – 75% gradients. Relative to southern Canada mixedgrass prairie, Yukon grasslands were likely species poor, had less total canopy cover, and produced less than half as much aboveground herb biomass (typically 200 – 300 kg/ha). The distribution of the sociations appeared limited to ~60˚ – 65˚ N latitude in the Yukon-Alaska region. Calamagrostis was the most abundant and widespread grassland sociation in the study area. The four sociations occupied less than 4% of the Carmacks – Pelly Crossing landscape, although they represented the most extensive high-latitude boreal grassland vegetation in Canada (≥ 2600 ha) and they were among the most northerly in North America. Key words: Beringia; boreal; ecology; grassland; palaeovegetation; plant community; sociation RÉSUMÉ. Les communautés de plantes graminoïdes en haute latitude (61,9˚ - 62 ,8˚ N) situées près de la limite nord du milieu de forêt boréale dans la région de Carmacks - Pelly Crossing, au Yukon, ont fait l’objet d’un échantillonnage et d’un classement.
