The aim of this study is to contribute additional information on the development of ERR_HeadB=ERR_HeadC=ERR_HeadB=ERR_HeadC/HeadB inflorescences in Cynodonteae by generating data on Distichlis, Bouteloua, Munroa, Erioneuron and Muhlenbergia ERR_HeadC=ERR_HeadD=ERR_HeadC=ERR_HeadD/HeadC and to compare them with results for other grasses. Using scanning electron microscopy images, we identified ERR_Extract3=ERR_HeadA=ERR_Extract1=ERR_HeadA common developmental patterns among grasses and described developmental novelties for Bouteloua, Distichlis INRE_HeadA=INRE_HeadB=INRE_HeadA=INRE_HeadB/HeadA and Muhlenbergia. Novel developmental features are: the amphipetal initiation of second-order branches along INRE_HeadB=INRE_HeadC=INRE_HeadB=INRE_HeadC/HeadB the inflorescence of B. curtipendula, the elongation of the internodes of the inflorescence branches before floral INRE_HeadC=INRE_HeadD=INRE_HeadC=INRE_HeadD/HeadC development in M. asperifolius and ‘Type II’ unisexual flowers in D. acerosa. Variable traits among studied species INRE_Extract3=INRE_HeadA=INRE_Extract1=INRE_HeadA are: inflorescence symmetry, direction of branch and spikelet initiation and differentiation, number of developing App_Head=App_HeadA=App_Head=App_HeadA/App_Head stamens, glume developmental patterns and timing of the arrest of gynoecium development during the formation BList1=SubBList1=BList1=SubBList of unisexual flowers. Our results allow us to postulate that a delicate balance of phytohormones may direct early BList1=SubBList3=BList1=SubBList2 development of grass inflorescence branching system by controlling direction of first-order branch differentiation.

  • A Vegetation Map of Carlsbad Caverns National Park, New Mexico 1
    ______________________________________________________________________________ A Vegetation Map of Carlsbad Caverns National Park, New Mexico ______________________________________________________________________________ 2003 A Vegetation Map of Carlsbad Caverns National Park, New Mexico 1 Esteban Muldavin, Paul Neville, Paul Arbetan, Yvonne Chauvin, Amanda Browder, and Teri Neville2 ABSTRACT A vegetation classification and high resolution vegetation map was developed for Carlsbad Caverns National Park, New Mexico to support natural resources management, particularly fire management and rare species habitat analysis. The classification and map were based on 400 field plots collected between 1999 and 2002. The vegetation communities of Carlsbad Caverns NP are diverse. They range from desert shrublands and semi-grasslands of the lowland basins and foothills up through montane grasslands, shrublands, and woodlands of the highest elevations. Using various multivariate statistical tools, we identified 85 plant associations for the park, many of them unique in the Southwest. The vegetation map was developed using a combination of automated digital processing (supervised classifications) and direct image interpretation of high-resolution satellite imagery (Landsat Thematic Mapper and IKONOS). The map is composed of 34 map units derived from the vegetation classification, and is designed to facilitate ecologically based natural resources management at a 1:24,000 scale with 0.5 ha minimum map unit size (NPS national standard). Along with an overview of the vegetation ecology of the park in the context of the classification, descriptions of the composition and distribution of each map unit are provided. The map was delivered both in hard copy and in digital form as part of a geographic information system (GIS) compatible with that used in the park.

This is the second largest family in the flora area after Asteraceae. A total of 97 taxa in 46 genera of grasses are included in this publication, which includes ones established and reproducing in the modern flora (86 taxa in 43 genera), some occurring at the margins of the flora area or no long known from the area, and ice age fossils. At least 28 taxa are known by fossils recovered from packrat middens, five of which have not been found in the modern flora: little barley ( Hordeum pusillum ), cliff muhly ( Muhlenbergia polycaulis ), Paspalum sp., mutton bluegrass ( Poa fendleriana ), and bulb panic grass ( Zuloagaea bulbosa ). Non-native grasses are represented by 27 species, or 28% of the modern grass flora.

Vascular plants and a brief history of the Kiowa and Rita Blanca National Grasslands. Gen. Tech. Rep. RMRS- GTR-233. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L. Hazlett is an ethnobotanist, Director of New World Plants and People consulting, and a research associate at the Denver Botanic Gardens, Denver, CO.

  • Floristic Surveys of Saguaro National Park Protected Natural Areas
    Floristic Surveys of Saguaro National Park Protected Natural Areas William L. Halvorson and Brooke S. Gebow, editors Technical Report No. 68 United States Geological Survey Sonoran Desert Field Station The University of Arizona Tucson, Arizona USGS Sonoran Desert Field Station The University of Arizona, Tucson The Sonoran Desert Field Station (SDFS) at The University of Arizona is a unit of the USGS Western Ecological Research Center (WERC). It was originally established as a National Park Service Cooperative Park Studies Unit (CPSU) in 1973 with a research staff and ties to The University of Arizona. Transferred to the USGS Biological Resources Division in 1996, the SDFS continues the CPSU mission of providing scientific data (1) to assist U.S. Department of Interior land management agencies within Arizona and (2) to foster cooperation among all parties overseeing sensitive natural and cultural resources in the region. It also is charged with making its data resources and researchers available to the interested public. Seventeen such field stations in California, Arizona, and Nevada carry out WERC’s work. The SDFS provides a multi-disciplinary approach to studies in natural and cultural sciences. Principal cooperators include the School of Renewable Natural Resources and the Department of Ecology and Evolutionary Biology at The University of Arizona. Unit scientists also hold faculty or research associate appointments at the university.
