Spores of Serpocaulon (Polypodiaceae): Morphometric and Phylogenetic Analyses
Grana, 2016 http://dx.doi.org/10.1080/00173134.2016.1184307 Spores of Serpocaulon (Polypodiaceae): morphometric and phylogenetic analyses VALENTINA RAMÍREZ-VALENCIA1,2 & DAVID SANÍN 3 1Smithsonian Tropical Research Institute, Center of Tropical Paleocology and Arqueology, Grupo de Investigación en Agroecosistemas y Conservación de Bosques Amazonicos-GAIA, Ancón Panamá, Republic of Panama, 2Laboratorio de Palinología y Paleoecología Tropical, Departamento de Ciencias Biológicas, Universidad de los Andes, Bogotá, Colombia, 3Facultad de Ciencias Básicas, Universidad de la Amazonia, Florencia Caquetá, Colombia Abstract The morphometry and sculpture pattern of Serpocaulon spores was studied in a phylogenetic context. The species studied were those used in a published phylogenetic analysis based on chloroplast DNA regions. Four additional Polypodiaceae species were examined for comparative purposes. We used scanning electron microscopy to image 580 specimens of spores from 29 species of the 48 recognised taxa. Four discrete and ten continuous characters were scored for each species and optimised on to the previously published molecular tree. Canonical correspondence analysis (CCA) showed that verrucae width/verrucae length and verrucae width/spore length index and outline were the most important morphological characters. The first two axes explain, respectively, 56.3% and 20.5% of the total variance. Regular depressed and irregular prominent verrucae were present in derived species. However, the morphology does not support any molecular clades. According to our analyses, the evolutionary pathway of the ornamentation of the spores is represented by depressed irregularly verrucae to folded perispore to depressed regular verrucae to irregularly prominent verrucae. Keywords: character evolution, ferns, eupolypods I, canonical correspondence analysis useful in phylogenetic analyses of several other Serpocaulon is a fern genus restricted to the tropics groups of ferns (Wagner 1974; Pryer et al. -

Growth of Fern Gametophytes After 20 Years of Storage in Liquid Nitrogen
FERN GAZ. 20(8): 337-346. 2018 337 GROWTH OF FERN GAMETOPHYTES AFTER 20 YEARS OF STORAGE IN LIQUID NITROGEN V. C. Pence Center for Conservation and Research of Endangered Wildlife (CREW) Cincinnati Zoo & Botanical Garden, 3400 Vine Street, Cincinnati, OH 45220, USA email: [email protected] Key words: cryopreservation, ex situ conservation, gametophyte; in vitro; long-term storage ABSTRACT In vitro grown gametophytes of six species of ferns, which had been cryopreserved using the encapsulation dehydration procedure, were evaluated for survival after 20 yrs of storage in liquid nitrogen. Tissues were rewarmed and transferred to a recovery medium with the same methods originally used to test pre-storage viability. All six species resumed growth. Post-storage viability was not consistently higher or lower than pre-storage viability of LN exposed tissues, likely reflecting the small sample sizes. However, these results demonstrate that long-term storage in liquid nitrogen is a viable option for preserving gametophytes of at least some fern species and could be utilized as an additional tool for preserving valuable gametophyte collections and for the ex situ conservation of fern biodiversity. INTRODUCTION For many species of ferns, gametophyte tissues have proven to be highly adaptable to growth in vitro (Table 1) . Most of these have been initiated through the aseptic germination of spores, although the aseptic germination of gemmae has also been demonstrated (Raine & Sheffield, 1997). As in vitro cultures, gametophytes can provide tissues for research and for propagation, both for ornamental ferns as well as for ferns of conservation concern. The ex situ conservation of ferns has traditionally relied on living collections and spore banks (Ballesteros, 2011). -

ATOLL RESEARCH BULLETIN NO. 503 THE VASCULAR PLANTS OF MAJURO ATOLL, REPUBLIC OF THE MARSHALL ISLANDS BY NANCY VANDER VELDE ISSUED BY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C., U.S.A. AUGUST 2003 Uliga Figure 1. Majuro Atoll THE VASCULAR PLANTS OF MAJURO ATOLL, REPUBLIC OF THE MARSHALL ISLANDS ABSTRACT Majuro Atoll has been a center of activity for the Marshall Islands since 1944 and is now the major population center and port of entry for the country. Previous to the accompanying study, no thorough documentation has been made of the vascular plants of Majuro Atoll. There were only reports that were either part of much larger discussions on the entire Micronesian region or the Marshall Islands as a whole, and were of a very limited scope. Previous reports by Fosberg, Sachet & Oliver (1979, 1982, 1987) presented only 115 vascular plants on Majuro Atoll. In this study, 563 vascular plants have been recorded on Majuro. INTRODUCTION The accompanying report presents a complete flora of Majuro Atoll, which has never been done before. It includes a listing of all species, notation as to origin (i.e. indigenous, aboriginal introduction, recent introduction), as well as the original range of each. The major synonyms are also listed. For almost all, English common names are presented. Marshallese names are given, where these were found, and spelled according to the current spelling system, aside from limitations in diacritic markings. A brief notation of location is given for many of the species. The entire list of 563 plants is provided to give the people a means of gaining a better understanding of the nature of the plants of Majuro Atoll. -

A Floristic Evaluation of the Natural Plant Communities and Grounds Occurring at The Key West Botanical Garden, Stock Island, Monroe County, Florida Steven W. 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. -
Davallia Denticulata L 1101000110101001210 D
J EDINBURGH UNIVERSITY LIBRARY Shelf Mark __l UniversityH Edinburgh 30150 024493592 Systematic Study on Davalliaceae in Peninsular Malaysia Haja Maideen Kader Maideen Doctor of Philosophy The University of Edinburgh Royal Botanic Garden Edinburgh 2008 Abstract Davalliaceae is a fern family established by A. B. Frank in 1877, based on the genus Davallia. It contains about 150 species in 8-12 genera and is restricted to the Old World tropics and subtropics. They are mostly epiphytes with long creeping fleshy rhizomes covered with peltate scales. In Peninsular Malaysia, the Davallioid ferns belong to Davallia Sm., Humata Cav., Leucostegia C. Presl and Araiostegia Copel. (Parris & Latiff, 1997). This study used morphological, cytological and molecular (three chloroplast regions) data in an attempt to classify Davalliaceae, especially in Peninsular Malaysia. The results presented in this thesis showed moderate to strong support for the paraphyly of genera in Davalliaceae, especially in Peninsular Malaysia. The results were incongruent with the latest classification based on morphology (Nooteboom, 1998) but congruent with a global study based on molecular data. The phylogeny showed that Leucostegia doest not belong to Davalliaceae. Four major clades were recognised in Davalliaceae, namely the Araiostegia Clade (AC); Davallia with two clades: Davallia Clade I (denticulata clade and dimorpha-divaricata clade), Davallia Clade II (scyphularia-solida clade and trichomanoides clade) and the Humata clade (HC). Maximum parsimony and Bayesian analyses of rps4 + rps4-trnS IGS and combined three regions produced congruent topologies, but the topologies ofrbcL and trnL-F region produced only slight differences. The expanded rbcL data also showed that all species were fully resolved without having a separated/regional clade. -
