"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. -
Resolution of Deep Angiosperm Phylogeny Using Conserved Nuclear Genes and Estimates of Early Divergence Times
ARTICLE Received 24 Mar 2014 | Accepted 11 Aug 2014 | Published 24 Sep 2014 DOI: 10.1038/ncomms5956 OPEN Resolution of deep angiosperm phylogeny using conserved nuclear genes and estimates of early divergence times Liping Zeng1, Qiang Zhang2, Renran Sun1, Hongzhi Kong3, Ning Zhang1,4 & Hong Ma1,5 Angiosperms are the most successful plants and support human livelihood and ecosystems. Angiosperm phylogeny is the foundation of studies of gene function and phenotypic evolution, divergence time estimation and biogeography. The relationship of the five divergent groups of the Mesangiospermae (B99.95% of extant angiosperms) remains uncertain, with multiple hypotheses reported in the literature. Here transcriptome data sets are obtained from 26 species lacking sequenced genomes, representing each of the five groups: eudicots, monocots, magnoliids, Chloranthaceae and Ceratophyllaceae. Phylogenetic analyses using 59 carefully selected low-copy nuclear genes resulted in highly supported relationships: sisterhood of eudicots and a clade containing Chloranthaceae and Ceratophyllaceae, with magnoliids being the next sister group, followed by monocots. Our topology allows a re-examination of the evolutionary patterns of 110 morphological characters. The molecular clock estimates of Mesangiospermae diversification during the late to middle Jurassic correspond well to the origins of some insects, which may have been a factor facilitating early angiosperm radiation. 1 State Key Laboratory of Genetic Engineering and Collaborative Innovation Center for Genetics and Development, Ministry of Education Key Laboratoryof Biodiversity Sciences and Ecological Engineering, Institute of Plant Biology, Institute of Biodiversity Science, Center for Evolutionary Biology, School of Life Sciences, Fudan University, 220 Handan Road, Yangpu District, Shanghai 200433, China. 2 Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and the Chinese Academy of Sciences, Guilin 541006, China. -
Wood Functional Anatomy of Chiococca Alba Hitch
Acta Biológica Catarinense 2017 Jan-Jun;4(1):52-61 Wood functional anatomy of Chiococca alba Hitch. (Rubiaceae) from cerrado Anatomia funcional da madeira de Chiococca alba Hitch. (Rubiaceae) de cerrado João Carlos Ferreira de MELO JÚNIOR1, 2, Maick William AMORIM¹, Gustavo Borda de OLIVEIRA¹ & Celso Voos VIEIRA¹ ABSTRACT Recebido em: 22 mar. 2017 The wood anatomy is able to evidence systematic and ecological aspects associated with Aceito em: 12 jun. 2017 the evolution and functionality of the secondary xylem. The present study was carried out using wood of Chiococca alba (Rubiaceae) from cerrado (savannah), to describe its anatomy and to verify if the hydraulic architecture of this species corroborates the theory that postulates the functional tendency that optimizes the transport efficiency associated with safety. The anatomical analysis followed the conventional protocols of wood anatomy. Different indexes of wood hydraulics quantification were calculated, such as solitary vessels index, vessel grouping, conductivity, vessel collapse, theoretical resistance to vessel implosion and mesomorphism. The structural characteristics described for C. alba are in agreement with the general anatomical descriptions for the Rubiaceae family that relate the presence of exclusively solitary vessels and small diameter, simple perforation plates, alternate intervessel pits, apotracheal parenchyma in species with non-septate fibers and narrow and heterogeneous rays. The calculated indexes showed that C. alba is a xerophyte species with great resistance to the collapse of the vessels during the transport of water, little vulnerability to embolism and relative efficiency in the transport when compared to other species of its subfamily (Cinchonoideae) in function of the typical low water availability of the savannah soil. -
Vascular Flora of Gus Engeling Wildlife Management Area, Anderson County, Texas
2003SOUTHEASTERN NATURALIST 2(3):347–368 THE VASCULAR FLORA OF GUS ENGELING WILDLIFE MANAGEMENT AREA, ANDERSON COUNTY, TEXAS 1 2,3 2 JASON R. SINGHURST , JAMES C. CATHY , DALE PROCHASKA , 2 4 5 HAYDEN HAUCKE , GLENN C. KROH , AND WALTER C. HOLMES ABSTRACT - Field studies in the Gus Engeling Wildlife Management Area, which consists of approximately 4465.5 ha (11,034.1 acres) of the Post Oak Savannah of Anderson County, have resulted in an annotated checklist of the vascular flora corroborating its remarkable species richness. A total of 930 taxa (excluding family names), belonging to 485 genera and 145 families are re- corded. Asteraceae (124 species), Poaceae (114 species), Fabaceae (67 species), and Cyperaceae (61 species) represented the largest families. Six Texas endemic taxa occur on the site: Brazoria truncata var. pulcherrima (B. pulcherrima), Hymenopappus carrizoanus, Palafoxia reverchonii, Rhododon ciliatus, Trades- cantia humilis, and T. subacaulis. Within Texas, Zigadenus densus is known only from the study area. The area also has a large number of species that are endemic to the West Gulf Coastal Plain and Carrizo Sands phytogeographic distribution patterns. Eleven vegetation alliances occur on the property, with the most notable being sand post oak-bluejack oak, white oak-southern red oak-post oak, and beakrush-pitcher plant alliances. INTRODUCTION The Post Oak Savannah (Gould 1962) comprises about 4,000,000 ha of gently rolling to hilly lands that lie immediately west of the Pineywoods (Timber belt). Some (Allred and Mitchell 1955, Dyksterhuis 1948) consider the vegetation of the area as part of the deciduous forest; i.e., burned out forest that is presently regenerating. -
Digging Deeper Project and Click “Join” on the Upper Right
ECOQUEST January 2021 WHAT IS AN ECOQUEST? EcoQuests, part of the Sarasota-Manatee Ecoflora Project, challenge Floridians to become engaged citizens in the DIGGING observation, study, appreciation, and conservation of the native flora and fauna of Florida, and understand the impacts to it by exotic species. DEEPER: HOW DO I GET STARTED? 1. Download the easy-to-use iNaturalist app on Indigenous Plants & your mobile device, or visit iNaturalist.org on your computer. 2. Set up a user account or sign in to join projects and People of Florida submit observations. 3. Visit the Sarasota-Manatee EcoFlora Digging Deeper project and click “join” on the upper right. 4. Photograph plants anywhere in Sarasota and Manatee Counties. Take multiple photos to show important features for identification (overall plant, leaves, flowers, fruit, stem). 5. Post your observations to iNaturalist. 6. Check out your ranking on this month’s challenge online! WHAT IS THE GOAL? Help us document as many of our featured indigenous plants as possible this January. Remember that any observation still contributes to the Sarasota-Manatee EcoFlora Project, even if it’s not featured in our monthly challenge. For this month’s EcoQuest, Digging Deeper, we are exploring the connection between Florida’s indigenous people and plants. Much of the ethnobotanical knowledge of American Indians is passed down through generations, as is the case with the Seminole and Miccosukee tribes. We know they relied upon plants for food and shelter, made dugout canoes of pine and cypress, and used plant fibers for textiles, crafting dolls and basket-making. Some of these traditions still exist today. -

Woodmansee [email protected] January 20, 2006 Submitted by The Institute for Regional Conservation 22601 S.W. 152 Avenue, Miami, Florida 33170 George D. Gann, Executive Director Submitted to CarolAnn Sharkey Key West Botanical Garden 5210 College Road Key West, Florida 33040 and Kate Marks Heritage Preservation 1012 14th Street, NW, Suite 1200 Washington DC 20005 Introduction The Key West Botanical Garden (KWBG) is located at 5210 College Road on Stock Island, Monroe County, Florida. It is a 7.5 acre conservation area, owned by the City of Key West. The KWBG requested that The Institute for Regional Conservation (IRC) conduct a floristic evaluation of its natural areas and grounds and to provide recommendations. Study Design On August 9-10, 2005 an inventory of all vascular plants was conducted at the KWBG. All areas of the KWBG were visited, including the newly acquired property to the south. Special attention was paid toward the remnant natural habitats. A preliminary plant list was established. Plant taxonomy generally follows Wunderlin (1998) and Bailey et al. (1976). Results Five distinct habitats were recorded for the KWBG. Two of which are human altered and are artificial being classified as developed upland and modified wetland. In addition, three natural habitats are found at the KWBG. They are coastal berm (here termed buttonwood hammock), rockland hammock, and tidal swamp habitats. Developed and Modified Habitats Garden and Developed Upland Areas The developed upland portions include the maintained garden areas as well as the cleared parking areas, building edges, and paths. -
Using ITS Sequences Suggests Lability in Reproductive Characters
MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 33 (2004) 127–139 www.elsevier.com/locate/ympev Phylogeny of Coreopsideae (Asteraceae) using ITS sequences suggests lability in reproductive characters Rebecca T. Kimballa,*, Daniel J. Crawfordb a Department of Zoology, University of Florida, P.O. Box 118525, Gainesville, FL 32611-8525, USA b Department of Ecology and Evolutionary Biology, The Natural History Museum and Biodiversity Research Center, University of Kansas, Lawrence, KS 66045-2106, USA Received 3 November 2003; revised 14 April 2004 Available online 7 July 2004 Abstract Relationships among the 21 genera within the tribe Coreopsideae (Asteraceae) remain poorly resolved despite phylogenetic stud- ies using morphological and anatomical traits. Recent molecular phylogenies have also indicated that some Coreopsideae genera are not monophyletic. We used internal transcribed spacer (ITS) sequences from representatives of 19 genera, as well as all major lin- eages in those genera that are not monophyletic, to examine phylogenetic relationships within this group. To examine the affects of alignment and method of analysis on our conclusions, we obtained alignments using five different parameters and analyzed all five alignments with distance, parsimony, and Bayesian methods. The method of analysis had a larger impact on relationships than did alignments, although different analytical methods gave very similar results. Although not all relationships could be resolved, a num- ber of well-supported lineages were found, some in conflict with earlier hypotheses. We did not find monophyly in Bidens, Coreopsis, and Coreocarpus, though other genera were monophyletic for the taxa we included. Morphological and anatomical traits which have been used previously to resolve phylogenetic relationships in this group were mapped onto the well-supported nodes of the ITS phy- logeny. -
Woody and Herbaceous Plants Native to Haiti for Use in Miami-Dade Landscapes1
Woody and Herbaceous Plants Native to Haiti For use in Miami-Dade Landscapes1 Haiti occupies the western one third of the island of Hispaniola with the Dominican Republic the remainder. Of all the islands within the Caribbean basin Hispaniola possesses the most varied flora after that of Cuba. The plants contained in this review have been recorded as native to Haiti, though some may now have been extirpated due in large part to severe deforestation. Less than 1.5% of the country’s original tree-cover remains. Haiti’s future is critically tied to re- forestation; loss of tree cover has been so profound that exotic fast growing trees, rather than native species, are being used to halt soil erosion and lessen the risk of mudslides. For more information concerning Haiti’s ecological plight consult references at the end of this document. For present purposes all of the trees listed below are native to Haiti, which is why non-natives such as mango (the most widely planted tree) and other important trees such as citrus, kassod tree (Senna siamea) and lead tree (Leucanea leucocephala) are not included. The latter two trees are among the fast growing species used for re-forestation. The Smithsonian National Museum of Natural History’s Flora of the West Indies was an invaluable tool in assessing the range of plants native to Haiti. Not surprisingly many of the listed trees and shrubs 1 John McLaughlin Ph.D. U.F./Miami-Dade County Extension Office, Homestead, FL 33030 Page | 1 are found in other parts of the Caribbean with some also native to South Florida. -
