    "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.

Kingston a, , Terry Harrison b a Department of Anthropology, Emory University, 1557 Dickey Dr., Atlanta, GA 30322, United States b Center for the Study of Human Origins, Department of Anthropology, New York University, 25 Waverly Place, New York, NY 10003, United States Received 20 September 2005; received in revised form 1 August 2006; accepted 4 August 2006 Abstract Major morphological and behavioral innovations in early human evolution have traditionally been viewed as responses to conditions associated with increasing aridity and the development of extensive grassland-savanna biomes in Africa during the Plio- Pleistocene. Interpretations of paleoenvironments at the Pliocene locality of Laetoli in northern Tanzania have figured prominently in these discussions, primarily because early hominins recovered from Laetoli are generally inferred to be associated with grassland, savanna or open woodland habitats. As these reconstructions effectively extend the range of habitat preferences inferred for Pliocene hominins, and contrast with interpretations of predominantly woodland and forested ecosystems at other early hominin sites, it is worth reevaluating the paleoecology at Laetoli utilizing a new approach. Isotopic analyses were conducted on the teeth of twenty-one extinct mammalian herbivore species from the Laetolil Beds (∼4.3–3.5 Ma) and Upper Ndolanya Beds (∼2.7–2.6 Ma) to determine their diet, as well as to investigate aspects of plant physiognomy and climate. Enamel samples were obtained from multiple localities at different stratigraphic levels in order to develop a high-resolution spatio-temporal framework for identifying and characterizing dietary and ecological change and variability within the succession.

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.

ABSTRACT - The Pliocene fossil record of hipparionine horses in the Indian Subcontinent is poorly known. Historically, only one species, “Hippotherium” antelopinum Falconer & Cautley, 1849, was described from the Upper Siwaliks. Here, we present the frst evidence of Eurygnathohippus Van Hoepen, 1930, a lineage hitherto only known from Africa, in the Upper Siwaliks during the late Pliocene. Morphologically, the South Asian Eurygnathohippus is most similar to Eurygnathohippus hasumense (Eisenmann, 1983) from Afar, Ethiopia, a species with a similar temporal range.

This locality has been recently calibrated at the Pliocene/Pleistocene boundary (2.6 ± 0.2 Ma) and therefore it is of interest for the first appearance of the genus Equus and last appearance of hipparionine horses. The Roca-Neyra equid sample, re- analyzed herein using morphological, morphometrical, and statistical analyses, has revealed the co-occurrence of Plesio- hipparion cf. ?P. rocinantis and Equus cf. E. livenzovensis. The analysis undertaken on several European, African, and Asian “Hipparion” sensu lato species from late Miocene to Early Pleistocene has revealed different remnant Hipparion lineages in the Plio-Pleistocene of Europe: Plesiohipparion, Proboscidippaion, and likely Cremohipparion.

Begerow Koreferent: Prof. Dr. R. Tollrian 2 ҅Fungi have a profound impact on global ecosystems. They modify our habitats and are essential for many ecosystem functions. Fungi form soil, recycle nutrients, decay wood, enhance plant growth and cull plants from their environment. They feed us, poison us, parasitize us and cure us. They destroy our crops, homes and libraries, but they also produce valuable biochemicals, such as ethanol and antibiotics. For both practical and intellectual reasons it is important to provide a phylogeny of Fungi on which a classi- fication can be firmly based. ҆ (Blackwell u.a. 2006) Inhaltsverzeichnis 3 Inhaltsverzeichnis Inhaltsverzeichnis ........................................................................................................... 3 Abbildungsverzeichnis .................................................................................................... 6 Tabellenverzeichnis ........................................................................................................ 7 Abkürzungsverzeichnis .................................................................................................. 8 1 Einleitung ............................................................................................................

This reference provides comprehensive information on the taxonomy and distribution in time and space of all currently recognised southern African fossil mammals. After an introductory background chapter on southern Africa, mammals, sites and dating, the following chapters are presented by epoch, covering the Eocene, Miocene, Pliocene, Pleistocene and Holocene. Individual maps provide information on where in the landscape specific taxa have been found, and a comprehensive index lists all the fauna and site locations. It ends with a chapter on how the book can be used, and lines of future research. Collecting a vast amount of information together in an accessible format, this is an essential reference for non-specialist taxonomists and palaeontologists, as well as for those using fossil data for other applications, such as archaeology, neontology and nature conservation. This title is also available as Open Access on Cambridge Core. D.

Herein, the authors report on skulls, mandibles and postcranial specimens of two species of Chinese Sivalhippus, S. ptychodus and S. platyodus. We frame our description and analyses within the context of newly described characters of the cheek teeth of Hippotherium from the Pannonian C of the Vienna Basin, the oldest and most primitive Old World hipparions. Our report includes original skull, mandibular and limited postcranial ma- terial of Sivalhippus ptychodus and skulls and dentitions of Sivalhippus platyodus from the Paleontological Museum of Uppsala (PMU, Uppsala, Sweden), the American Museum of Natural History (AMNH, New York, USA) and the Licent Collection in Tianjin Natural History Museum (Tianjin, China). The skull, maxillary and mandibular material we attribute to Sivalhippus ptychodus and Sivalhippus platyodus exhibit some primitive features for Old World hipparions and synapamorphies of the face and dentition that unite it with the Sivalhippus clade.
