  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

    Medical Research Archives The Vascular Flora of Back Bay National Wildlife Refuge and False Cape State Park, Virginia The Vascular Flora of Back Bay National Wildlife Refuge and False Cape State Park, Virginia Richard Stalter* and Eric E. Lamont ** Department of Biological Sciences, St. John's University, Jamaica, NY 11439 New York Botanical Garden, Bronx, NY 10458 *Corresponding Author Dr. Richard Stalter ( [email protected] ) Copyright 2015 KEI Journals. All rights reserved. Medical Research Archives The Vascular Flora of Back Bay National Wildlife Refuge and False Cape State Park, Virginia ABSTRACT The vascular flora of Bay National Wildlife Refuge and False Cape State Park, Virginia consists of 602 species within 343 genera and 123 families. Of these 519 are native (86%) while 83 are not native to the region. Thirty two species are listed as rare or endangered in Virginia including two small populations of Bartonia verna at False Cape State Park found nowhere else in the state. Several species with southern affinities reach their northern range limit on the Back Bay region, whereas only two northern taxa, Hudsonia tomentosa and Myrica pensylvania are near their southern limit. Non-native varieties of Phragmites australis are a major component of the natural vegetation and pose a threat to native taxa. Each taxonomic entry in the checklist is accompanied by an annotation which includes the locality and habitat in which each taxon occurs, frequence of occurrence, range extensions, rarity status, and pertinent synonyms. Key words : flora, distribution, biodiversity, Back Bay National Wildlife Refuge, False Cape State Park, Virginia. Copyright 2015 KEI Journals.

  • Floristic Quality Assessment Report
    FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al.

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.

    M acroflora y macrofauna de los sistemas estuarinos de Michoacán, México Andrea Raz-Guzmán Posgrado en Ciencias del Mar y Limnología. UNAM Resumen Los sistemas estuarinos michoacanos han sido estudiados escasamente. Por esto se muestrearon 22 sistemas para registrar la macroflora y macrofauna, registros nuevos, especies bajo algún estatus, especies de importancia comercial y su distribución espacial. Las especies recolectadas y las registradas en la literatura sumaron 123 (29 plantas, 94 animales). Las familias mejor representadas fueron Cyperaceae, Palaemonidae, Gobiidae y Carangidae. Los registros nuevos incluyen 29 especies de plantas, 7 de insectos, 2 de crustáceos, 15 de moluscos y 3 de peces. Las especies bajo algún estatus son Rhizophora mangle , Avicennia germinans , Conocarpus erectus , Laguncularia racemosa y Poecilia butleri . Phragmites australis , Typha domingensis , Macrobrachium hobbsi y M. tenellum presentaron las distribuciones más amplias. Los sistemas con más especies fueron Santa Ana, Salinas del Padre, Nexpa y Coahuayana. Diez especies de plantas y Stramonita biserialis son ornamentales. Los coleópteros, hemípteros y odonatos son depredadores de larvas de mosquitos y, junto con Macrobrachium digueti , son bioindicadores de la calidad del agua. Litopenaeus vannamei , M. americanum y 19 especies de peces sostienen pesquerías importantes, mientras que Callinectes arcuatus , C. toxotes y Cardisoma crassum se comercializan localmente. Melanoides tuberculata es introducido, oportunista, hospedero de tremátodos parásitos, no Ciencia Nicolaita # 76 46 Abril de 2019 Macroflora y macrofauna de los sistemas estuarinos de Michoacán, México registrado para Michoacán y no regulado en el país. La riqueza de especies estuarinas en Michoacán es marcadamente baja en respuesta a sus lagunas y esteros pequeños y oligo-mesohalinos y la resultante heterogeneidad ambiental baja, así como al reducido número de estudios enfocados específicamente a los sistemas estuarinos.
