En promedio, el rendimiento de forraje verde, materia seca y calidad de forraje fueron superiores al del monocultivo de avena (p<0.05). El porcentaje de proteína cruda se incrementó en la medida que creció la proporción de vicia común en la asocia- ción, acompañado de una disminución del contenido de fibra. En cuanto a los índices de competencia, el cultivo asociado de avena con vicia favorece el rendimiento relativo total de forraje (LERtotal>1). Ninguna de las especies manifestó comportamiento agresivo (A=0). Se observó mayor capacidad competitiva de la vicia común (CR>1) comparado con la capacidad competitiva de la avena. Palabras clave: cultivo asociado; rendimiento; calidad de forraje; competencia interespecífica ABSTRACT The oats (Avena sativa) and common vetch (Vicia sativa) cultivated in association was evaluated under dry land conditions at 4035 m above sea level to determine its performance and effects on yield, forage quality and interspecific competition.

  • Davis Expedition Fund Report on Expedition / Project
    DAVIS EXPEDITION FUND REPORT ON EXPEDITION / PROJECT Expedition/Project Title: Biogeography and Systematics of South American Vicia (Leguminosae) Travel Dates: 28/09/2010 – 12/11/2010 Location: Northern Chile and northern Argentina Group Members: Paulina Hechenleitner Collection of research material of Vicia in the form of Aims: herbarium specimens, habitat data, digital images, silica- dried leaf samples, and base-line data on the IUCN conservation status of Vicia. Outcome (not less than 300 words):- See attached report. Report for the Davis Expedition Fund Biogeography and Systematics of South American Vicia (Leguminosae) Botanical fieldwork to northern Chile and northern Argentina 28th of Sep to 12th of November 2010 Paulina Hechenleitner January 2011 Introduction Vicia is one of five genera in tribe Fabeae, and contains some of humanity's oldest crop plants, and is thus of great economic importance. The genus contains around 160 spp. (Lewis et al. 2005) distributed throughout temperate regions of the northern hemisphere and in temperate S America. Its main centre of diversity is the Mediterranean with smaller centres in North and South America (Kupicha, 1976). The South American species are least known taxonomically. Vicia, together with Lathyrus and a number of other temperate plant genera share an anti- tropical disjunct distribution. This biogeographical pattern is intriguing (Raven, 1963): were the tropics bridged by long distance dispersal between the temperate regions of the hemispheres, or were once continuous distributions through the tropics severed in a vicariance event? Do the similar patterns seen in other genera reflect similar scenarios or does the anti-tropical distribution arise in many different ways? The parallels in distribution, species numbers and ecology between Lathyrus and Vicia are particularly striking.

  • Overview of Vicia (Fabaceae) of Mexico
    24 LUNDELLIA DECEMBER, 2014 OVERVIEW OF VICIA (FABACEAE) OF MEXICO Billie L. Turner Plant Resources Center, The University of Texas, 110 Inner Campus Drive, Stop F0404, Austin TX 78712-1711 [email protected] Abstract: Vicia has 12 species in Mexico; 4 of the 12 are introduced. Two new names are proposed: Vicia mullerana B.L. Turner, nom. & stat. nov., (based on V. americana subsp. mexicana C.R. Gunn, non V. mexicana Hemsl.), and V. ludoviciana var. occidentalis (Shinners) B.L. Turner, based on V. occidentalis Shinners, comb. nov. Vicia pulchella Kunth subsp. mexicana (Hemsley) C.R. Gunn is better treated as V. sessei G. Don, the earliest name at the specific level. A key to the taxa is provided along with comments upon species relationships, and maps showing distributions. Keywords: Vicia, V. americana, V. ludoviciana, V. pulchella, V. sessei, Mexico. Vicia, with about 140 species, is widely (1979) provided an exceptional treatment distributed in temperate regions of both of the Mexican taxa, nearly all of which were hemispheres (Kupicha, 1982). Some of the illustrated by full-page line sketches. As species are important silage, pasture, and treated by Gunn, eight species are native to green-manure legumes. Introduced species Mexico and four are introduced. I largely such as V. faba, V. hirsuta, V. villosa, and follow Gunn’s treatment, but a few of his V. sativa are grown as winter annuals in subspecies have been elevated to specific Mexico, but are rarely collected. Gunn rank, or else treated as varieties. KEY TO THE SPECIES OF VICIA IN MEXICO (largely adapted from Gunn, 1979) 1.

  • Community Planning and Economic Development Creating Solutions for Our Future Joshua Cummings, Director
    COUNTY COMMISSIONERS John Hutchings District One Gary Edwards District Two Tye Menser District Three Community Planning and Economic Development Creating Solutions for Our Future Joshua Cummings, Director 2020 Thurston County Community Planning Field Screening Guidelines for Prairie Habitat Section 1 - 1.1 Purpose Under the development of the Habitat Conservation Plan (HCP), it is the long-term goal of Thurston County to conserve and restore large, intact areas of prairie habitat in addition to smaller tracts of land within 1/2 mi of larger prairies (Chapter 24.25.065 Thurston County Code (TCC)). While the screening process described in this protocol focuses on the detection of diagnostic prairie flora listed in the CAO, the overall intention for prairie conservation under the CAO and pending the HCP is to protect a much broader range of prairie butterflies, birds and mammals, and habitat. South Puget Sound Prairie ecosystems support a wide range of rare flora and fauna, some of which are listed under federal or state protection, including butterflies which are considered Species of Conservation Concern (SCC) or Greatest Conservation Need (SGCN). Particular attention is given to the protection of federally listed and imperiled butterfly species in Thurston County, such as the Taylor’s checkerspot (TCB, Euphydryas editha taylori), Puget blue (Icaria icarioides blackmorei), hoary elfin (Callophrys polios), Oregon branded skipper (Hesperia Colorado oregonia), Mardon skipper (Polites mardon), and valley silverspot (Speyeria zerene) butterflies, and the plant species known to serve as host and nectar plants for these butterflies. Other federally listed and candidate prairie species include the streaked horned lark (Eromophila alpestris strigata), Mazama pocket gopher (Thomomys mazama), and the Oregon vesper sparrow (Pooecetes gramineus).
