  • Lesser Prairie-Chicken Habitat Map for Portions of Eastern New Mexico
    ________________________________________________________________________ Lesser Prairie-Chicken Habitat Map for Portions of Eastern New Mexico ________________________________________________________________________ 16 November 2005 Lesser Prairie-Chicken Habitat Map for 1 Portions of Eastern New Mexico Paul Neville, Teri Neville, and Kristine Johnson2 ABSTRACT The purpose of this project was to provide a map depicting the extent and location of lesser prairie-chicken habitat in New Mexico. The 923,441 ha (2,281,868 ac) study area includes most of the remaining occupied habitat for the lesser prairie-chicken in the state. We used field data in conjunction with satellite imagery and aerial photography to create a vegetation map. We classified the map according to plant associations and subsequently regrouped it into map units that incorporated landforms, to reflect the habitat requirements of lesser prairie-chickens. We performed GIS analyses incorporating vegetation type, patch size, and fragmentation to identify areas of high quality lesser prairie-chicken habitat. These analyses demonstrate that only three places within the mapped area contain large patches of suitable habitat, and one of those is south of US 380, where LPCH populations are already sparse and scattered. The GIS analyses also indicate that the vast majority of high-quality vegetation types occur in patches smaller than 3200 ha, rendering them by most definitions below the minimum size required by LPCH. Used in combination with GIS analysis and current LPCH population data, the map represents a powerful management, planning, and monitoring tool. 1 Draft Final report submitted 31 August 2005 in partial fulfillment of Task Order 5 to Cooperative Agreement No. GDA010009 between Natural Heritage New Mexico at the University of New Mexico and Bureau of Land Management; Work Order No.

  • Final Report
    Final Report Final pre-release investigations of the gorse thrips (Sericothrips staphylinus) as a biocontrol agent for gorse (Ulex europaeus) in North America Date: August 31, 2012 Award Number: 10-CA-11420004-184 Report Period: June 1, 2010– May 31, 2012 Project Period: June 1, 2010– May 31, 2012 Recipient: Oregon State University Recipient Contact Person: Fritzi Grevstad Principal Investigator/ Project Director: Fritzi Grevstad Introduction Gorse (Ulex europaeus) is an environmental weed classified as noxious in the states of Washington, Oregon, California, and Hawaii. A classical biological control program has been applied in Hawaii with the introduction of 4 gorse-feeding arthropods, but only two of these (a mite and a seed weevil) have been introduced to the mainland U.S. The two insects that have not yet been introduced include the gorse thrips, Sericothips staphylinus (Thysanoptera: Thripidae), and the moth Agonopterix umbellana (Lepidoptera: Oecophoridae). With prior support from the U.S. Forest Service (joint venture agreement # 07-JV-281), we were able to complete host specificity testing of S. staphylinus on 44 North American plant species that were on the original test plant list. However, following review of the proposed Test Plant List, the Technical Advisory Group on Biocontrol of Weeds (TAG) recommended that we include an additional 18 plant species for testing. In this report, we present host specificity testing and related objectives necessary to bring the program to the implementation stage. Objectives (1) Acquire and grow the additional 18 species of plants recommended by the TAG. (2) Complete host specificity trials for the gorse thrips on the 18 plant species.

A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains,

  • 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. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

University of Cape Town BOLUS LIBRARY C24 0005 5091 Abstract 1111111111111 The pollen morphlogy of 34 species of Clutia L. (Euphorbiaceae) has been studied by light and scanning electron microscopy. The grains are medium sized, prolate to subprolate and rarely prolate spheroidal, tricolporate and distinctly tectate. The tectum is reticulate to punctate and the lumina are variable in size and shape. Pollen dimensions were found to be of no significance in defining infrageneric relationships while reticulation pattern, pitting density and roughnes of the exine distinguished several pollen groups when analysed by multivariate methods. The three large groups maintained their integrity regardless of method of multivariate analysis employed. A further comparison with the sections of Clutia suggested by Pax (1911) and Prain (1913) gave substantial support for some of these sections.Type ED 1 is characterised by irregular exine pits and rough tecta and is correlated to the section C. alatemoideae recognized by both workers in earlier sectioning of Clutia. Type RT 1 I corresponds to C. abyssinica and C.

Osborne2 FAMILY: Euphorbiaceae GENUS: Codiaeum SPECIFIC EPITHET: variegatum CULTIVARS: ‘Banana’, ‘Gold Dust’, ‘Mammy’, ‘Norma’, ‘Petra’, ‘Sunny Star’ and many others. Crotons have been popular in tropical gardens for centuries. Crotons grow into shrubs and small trees in their native habitats of India, Malaysia, and some of the South Pacific islands. Few other plants can surpass them in both foliage color and leaf shape variation. Leaf colors range from reds, oranges and yellows to green with all combinations of variegated colors. Leaf shapes vary from broad and elliptical to narrow and almost linear. Leaf blades range from flat to cork-screw-shaped. Since some cultivars are tolerant of interior environments, crotons have also become very popular as interior potted foliage plants. One additional point, often overlooked, is that foliage of crotons Figure 1. Crotons are useful for adding color to floral arrangements, is excellent material for use in floral arrangements.

  • Boraginaceae), with an Emphasis on the Popcornflowers (Plagiobothrys)
    Diversification, biogeography, and classification of Amsinckiinae (Boraginaceae), with an emphasis on the popcornflowers (Plagiobothrys) By Christopher Matthew Guilliams A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Bruce G. Baldwin, Chair Professor David Ackerly Professor Brent Mishler Professor Patrick O'Grady Summer 2015 Abstract Diversification, biogeography, and classification of Amsinckiinae (Boraginaceae), with an emphasis on the popcornflowers (Plagiobothrys) by Christopher Matthew Guilliams Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Bruce G. Baldwin, Chair Amsinckiinae is a diverse and ecologically important subtribe of annual herbaceous or perennial suffrutescent taxa with centers of distribution in western North America and southern South America. Taxa in the subtribe occur in all major ecosystems in California and more broadly in western North America, from the deserts of Baja California in the south where Johnstonella and Pectocarya are common, north to the ephemeral wetland ecosystems of the California Floristic Province where a majority of Plagiobothrys sect. Allocarya taxa occur, and east to the Basin and Range Province of western North America, where Cryptantha sensu stricto (s.s.) and Oreocarya are well represented. The subtribe minimally includes 9 genera: Amsinckia, Cryptantha s.s., Eremocarya, Greeneocharis, Harpagonella, Johnstonella, Oreocarya, Pectocarya, and Plagiobothrys; overall minimum-rank taxonomic diversity in the subtribe is ca. 330-342 taxa, with ca. 245--257 taxa occurring in North America, 86 in South America, and 4 in Australia. Despite their prevalence on the landscape and a history of active botanical research for well over a century, considerable research needs remain in Amsinckiinae, especially in one of the two largest genera, Plagiobothrys.
