  • Biodiversity in Forests of the Ancient Maya Lowlands and Genetic
    Biodiversity in Forests of the Ancient Maya Lowlands and Genetic Variation in a Dominant Tree, Manilkara zapota (Sapotaceae): Ecological and Anthropogenic Implications by Kim M. Thompson B.A. Thomas More College M.Ed. University of Cincinnati A Dissertation submitted to the University of Cincinnati, Department of Biological Sciences McMicken College of Arts and Sciences for the degree of Doctor of Philosophy October 25, 2013 Committee Chair: David L. Lentz ABSTRACT The overall goal of this study was to determine if there are associations between silviculture practices of the ancient Maya and the biodiversity of the modern forest. This was accomplished by conducting paleoethnobotanical, ecological and genetic investigations at reforested but historically urbanized ancient Maya ceremonial centers. The first part of our investigation was conducted at Tikal National Park, where we surveyed the tree community of the modern forest and recovered preserved plant remains from ancient Maya archaeological contexts. The second set of investigations focused on genetic variation and structure in Manilkara zapota (L.) P. Royen, one of the dominant trees in both the modern forest and the paleoethnobotanical remains at Tikal. We hypothesized that the dominant trees at Tikal would be positively correlated with the most abundant ancient plant remains recovered from the site and that these trees would have higher economic value for contemporary Maya cultures than trees that were not dominant. We identified 124 species of trees and vines in 43 families. Moderate levels of evenness (J=0.69-0.80) were observed among tree species with shared levels of dominance (1-D=0.94). From the paleoethnobotanical remains, we identified a total of 77 morphospecies of woods representing at least 31 plant families with 38 identified to the species level.

However, this tremendous diversity is underpinned by a sur- prisingly robust basic floral structure in which a central group of carpels forms on an axis of determinate growth, almost invariably surrounded by two successive zones containing stamens and perianth organs, respectively. Over the last 25 years, remarkable progress has been achieved in describing the molecular mechanisms that control http://aob.oxfordjournals.org/ almost all aspects of flower development, from the phase change that initiates flowering to the final production of fruits and seeds. However, this work has been performed almost exclusively in a small number of eudicot model species, chief among which is Arabidopsis thaliana. Studies of flower development must now be extended to a much wider phylogenetic range of flowering plants and, indeed, to their closest living relatives, the gymnosperms.

  • Complete Inventory
    Maya Ethnobotany Complete Inventory of plants 1 Tenth edition, Christmas week December 2011 Maya Ethnobotany Complete Inventory:: fruits,nuts, root crops, grains,construction materials, utilitarian uses, sacred plants, sacred flowers Guatemala, Mexico, Belize, Honduras Nicholas M. Hellmuth Maya Ethnobotany Complete Inventory of plants 2 Introduction This opus is a progress report on over thirty years of studying plants and agriculture of the present-day Maya with the goal of understanding plant usage by the Classic Maya. As a progress report it still has a long way to go before being finished. But even in its unfinished state, this report provides abundant listings of plants in a useful thematic arrangement. The only other publication that I am familiar with which lists even close to most of the plants utilized by the Maya is in an article by Cyrus Lundell (1938). • Obviously books on Mayan agriculture should have informative lists of all Maya agricultural crops, but these do not tend to include plants used for house construction. • There are monumental monographs, such as all the trees of Guatemala (Parker 2008) but they are botanical works, not ethnobotanical, and there is no cross-reference by kind of use. You have to go through over one thousand pages and several thousand tree species to find what you are looking for. • There are even important monographs on Maya ethnobotany, but they are usually limited to one country, or one theme, often medicinal plants. • There are even nice monographs on edible plants of Central America (Chízmar 2009), but these do not include every local edible plant, and their focus is not utilitarian plants at all, nor sacred plants.

MOYA LÓPEZ Abstract The nomenclature and typification of Pseudophoenix, a neotropical genus of four species, are reviewed and updated. Plumier's involvement in the description of P. vinifera is reported and discussed, and unpublished Plumier illustrations of the species present at the National Museum of Natural History in Paris are published. Resumen Se revisa y actualizan la nomenclatura y los tipos de Pseudophoenix, un género neotropical de cuatro especies. Se informa y discute la participación de Plumier en la descripción de P. vinifera, y se publican las ilustraciones inéditas de Plumier de las especies presentes en el Museo Nacional de Historia Natural de París. Introduction Pseudophoenix consists of four species of mostly insular distribution in the Caribbean basin. They are known for their handsome trunks, these often swollen, white, and with attractive, dark, ring- like leaf scars; plumose, pinnate leaves; and infructescences with showy, reddish fruits (Fig. 1). Three species are restricted to the island of Hispaniola, P. ekmanii (southwestern Dominican Republic), P. lediniana (southern Haiti), and P. vinifera (Haiti and Dominican Republic), while the fourth, P. sargentii, the most widely distributed of the four species, occurs in Belize, Cuba, Dominica, Dominican Republic, Haiti, Mexico (Yucatán Peninsula), Puerto Rico, The Bahamas, Turks and Caicos Islands, and U.

  • Notes on Cuban Native Palms
    Willdenowia 36 – 2006 507 ANGELA LEIVA SÁNCHEZ Notes on Cuban native palms Abstract Leiva Sánchez, A.: Notes on Cuban native palms. – Willdenowia 36 (Special Issue): 507-513. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem. doi:10.3372/wi.36.36148 (available via http://dx.doi.org/) A brief, updated account on the taxonomic history of Cuban palms is provided, together with a key for the field identification of the 14 currently recognized native genera. Four of the most interesting genera of Cuban native palms (Thrinax, Coccothrinax, Copernicia and Roystonea) are commented. The name Coccothrinax crinita is lectotypified. Key words: Cuba, Arecaceae, taxonomic history, lectotypification. Introduction Palms are ubiquitous in the Cuban landscape. It is almost impossible to spend a day in this coun- try without seeing at least one palm species. As an indicator of the frequency of palms, 206 geo- graphical localities are named after palms (Leiva 1999). About 81 indigenous palm species in 14 genera are known from the various ecosystems of the island. Since many years Cuban palms have drawn the attention of Cuban scientists as well as those from foreign countries. A brief historical overview The scientific knowledge of Cuban palms began with the discovery and collection of the first palms by Alexander von Humboldt and Aimé Bonpland. They were described and published by Kunth (1815): Cocos crispa Kunth (today: Acrocomia crispa (Kunth) Becc.), Corypha mira- guama Kunth (today: Coccothrinax miraguama (Kunth) Becc.), Oreodoxa regia Kunth (today: Roystonea regia (Kunth) O. F. Cook). These are very common palms in Cuba. Botanists such as C. F. P.

Les analyses phylogénétiques conduites dans la famille, incorporant des schémas de datation moléculaire calibrés à l’aide de fossiles, montrent de nettes discontinuités dans l’histoire évolutive de ce groupe de plantes au cours du Cénozoïque, coïncidant clairement avec des phénomènes paléoclimatiques et géologiques majeurs. En particulier, un ensemble de phylogénies moléculaires conduites à divers niveaux sur un groupe pris comme modèle, la sous-tribu néotropicale des Bactridinae, nous a permis d’identifier quatre signaux de diversification dans la structure phylogénétique, particulièrement significatifs

El Rocío, km 3 1/2 Distribution Calabazar, CP 19230 Ciudad de La Habana, Cuba and [email protected] Conservation Cuba has a rich palm flora despite its relatively small territory. The palms play an important role in Cuba's landscape and vegetation and in the everyday life of Cuban people, who have multiple uses for these plants (Muñiz & Borhidi 1982). The goal of this study is to up-date the list of Roystonea (Zona 1996), Sabal (Zona 1990) and Cuban palms given by León (1946), taking into Thrinax (Read 1975), as well as the revision of consideration the revisions of several palm Bactris for the Caribbean (Salzman & Judd 1995). genera from the new world and the new species The most recent additions to the list of palms reported for Cuba. This new checklist will allow from Cuba by Moya et al. (1991), Zona (1992) future publications to use the correct and Borhidi and Hernández (1993) were also nomenclature. included. In preparing this checklist, we reviewed the The family Palmae in Cuba is represented by 15 following lists of Cuban species: Grisebach (1866), genera, two subgenera and 81 species, six hybrids Sauvalle (1868), Beccari (1912, 1913), Dahlgren and nine infraspecific taxa for a total of 96 (1936), León (1946), Alain (1969), Muñiz and indigenous palms (Table 1).
