    "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.

Therefore, the types of mycoheterotrophic plant are very abundant in tropical areas. One of the areas in Indonesia with the tropics is North Sumatera province. Unfortunately, the information about the species of mycoheterotrophic in North Sumatra is still limited. The objective of the research was to figure out the types of mycoheterotrophic plants in North Sumatra. The study was conducted in August until October 2019 in several areas of the Natural Resources Conservation Hall (BBKSDA) of North Sumatra province, the nature Reserve and nature Park. The research sites covered Tinggi Raja Nature Reserve, Dolok Sibual-Buali Nature Reserve, Sibolangit Tourist Park and Sicike-Cike Natural Park. In conducting sampling, the method used was through exploration or cruising method.

Using historical data from an aviation operations data provider, national governments, international agencies, and aircraft emissions modelling software, this paper details a global, transparent, and geographically allocated CO2 inventory for commercial aviation.

  • The Natural Communities of South Carolina

    The Natural Communities of South Carolina

    THE NATURAL COMMUNITIES OF SOUTH CAROLINA BY JOHN B. NELSON SOUTH CAROLINA WILDLIFE & MARINE RESOURCES DEPARTMENT FEBRUARY 1986 INTRODUCTION The maintenance of an accurate inventory of a region's natural resources must involve a system for classifying its natural communities. These communities themselves represent identifiable units which, like individual plant and animal species of concern, contribute to the overall natural diversity characterizing a given region. This classification has developed from a need to define more accurately the range of natural habitats within South Carolina. From the standpoint of the South Carolina Nongame and Heritage Trust Program, the conceptual range of natural diversity in the state does indeed depend on knowledge of individual community types. Additionally, it is recognized that the various plant and animal species of concern (which make up a significant remainder of our state's natural diversity) are often restricted to single natural communities or to a number of separate, related ones. In some cases, the occurrence of a given natural community allows us to predict, with some confidence, the presence of specialized or endemic resident species. It follows that a reasonable and convenient method of handling the diversity of species within South Carolina is through the concept of these species as residents of a range of natural communities. Ideally, a nationwide classification system could be developed and then used by all the states. Since adjacent states usually share a number of community types, and yet may each harbor some that are unique, any classification scheme on a national scale would be forced to recognize the variation in a given community from state to state (or region to region) and at the same time to maintain unique communities as distinctive.

    Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands

    SMITHSONIAN INSTITUTION Contributions from the United States National Herbarium Volume 52: 1-415 Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands Editors Pedro Acevedo-Rodríguez and Mark T. Strong Department of Botany National Museum of Natural History Washington, DC 2005 ABSTRACT Acevedo-Rodríguez, Pedro and Mark T. Strong. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Contributions from the United States National Herbarium, volume 52: 415 pages (including 65 figures). The present treatment constitutes an updated revision for the monocotyledon and gymnosperm flora (excluding Orchidaceae and Poaceae) for the biogeographical region of Puerto Rico (including all islets and islands) and the Virgin Islands. With this contribution, we fill the last major gap in the flora of this region, since the dicotyledons have been previously revised. This volume recognizes 33 families, 118 genera, and 349 species of Monocots (excluding the Orchidaceae and Poaceae) and three families, three genera, and six species of gymnosperms. The Poaceae with an estimated 89 genera and 265 species, will be published in a separate volume at a later date. When Ackerman’s (1995) treatment of orchids (65 genera and 145 species) and the Poaceae are added to our account of monocots, the new total rises to 35 families, 272 genera and 759 species. The differences in number from Britton’s and Wilson’s (1926) treatment is attributed to changes in families, generic and species concepts, recent introductions, naturalization of introduced species and cultivars, exclusion of cultivated plants, misdeterminations, and discoveries of new taxa or new distributional records during the last seven decades.

F. T. Merckx ● Richard M. K. Saunders ● Dianxiang Zhang 1 Received: 9 July 2020 / Revised: 29 November 2020 / Accepted: 7 December 2020 / Published online: 6 January 2021 © The Author(s) 2021. This article is published with open access Abstract Mycoheterotrophic plants (MHPs) growing on arbuscular mycorrhizal fungi (AMF) usually maintain specialized mycorrhizal associations. The level of specificity varies between MHPs, although it remains largely unknown whether interactions with mycorrhizal fungi differ by plant lineage, species, and/or by population. Here, we investigate the mycorrhizal interactions among Burmannia species (Burmanniaceae) with different trophic modes using high-throughput DNA sequencing. We characterized the inter- and intraspecific dynamics of the fungal communities by assessing the composition and diversity of fungi among sites. We found that fully mycoheterotrophic species are more specialized in their 1234567890();,: 1234567890();,: fungal associations than chlorophyllous species, and that this specialization possibly results from the gradual loss of some fungal groups. In particular, although many fungal species were shared by different Burmannia species, fully MHP species typically host species-specific fungal assemblages, suggesting that they have a preference for the selected fungi. Although no apparent cophylogenetic relationship was detected between fungi and plants, we observe that evolutionarily closely related plants tend to have a greater proportion of shared or closely related fungal partners. Our findings suggest a host preference and specialization toward fungal assemblages in Burmannia, improving understanding of interactions between MHPs and fungi.
