  • Red Ring Disease of Coconut Palms Is Caused by the Red Ring Nematode (Bursaphelenchus Cocophilus), Though This Nematode May Also Be Known As the Coconut Palm Nematode
    1 Red ring disease of coconut palms is caused by the red ring nematode (Bursaphelenchus cocophilus), though this nematode may also be known as the coconut palm nematode. This disease was first described on coconut palms in 1905 in Trinidad and the association between the disease and the nematode was reported in 1919. The vector of the nematode is the South American palm weevil (Rhynchophorus palmarum), both adults and larvae. The nematode parasitizes the weevil which then transmits the nematode as it moves from tree to tree. Though the weevil may visit many different tree species, the nematode only infects members of the Palmae family. The nematode and South American palm weevil have not yet been observed in Florida. 2 Information Sources: Brammer, A.S. and Crow, W.T. 2001.

    Meeting of the Network for Neotropical Biogeography 4th Program and Abstracts PANAMA - January 14-17, 2015 Smithsonian Tropical Research Institute Program 4th Meeting of the Network for Neotropical Biogeography NNB4 Smithsonian Tropical Research Institute 14-17 January, 2015 This meeting is being hosted by the Smithsonian Tropical Research Institute (STRI), and financially supported by the Smithsonian Tropical Research Institute, Indicasat and the Florida Museum of Natural History/University of Florida. Organizers Liliana Londoño and Carlos Jaramillo, STRI PANAMA CHANGED THE WORLD! The Isthmus of Panama emerged from the sea millions of years ago, joining two continents and producing one of the largest vicariance events in Earth’s history: the Great American Biotic Interchange (GABI). At that time, marine populations were separated while terrestrial plants and animals underwent massive migrations between North and South America, dramatically changing the Earth. The rise of the isthmus also impacted atmospheric and oceanic circulation, including substantial changes in Atlantic and Caribbean salinity. There is no better place to have a symposium on Neotropical Biogeography! 1 NETWORK FOR NEOTROPICAL BIOGEOGRAPHY Tropical America – the Neotropics – is the most species-rich region on Earth. Understanding the mechanisms underlying the historical assembly and evolution of this extreme biodiversity constitutes a major challenge in biology, and will require hitherto unrealized inter- disciplinary scientific collaboration. The primary goals of this network are to: • Promote scientific interaction • Stimulate the exchange of material, students and researchers • Increase inter-disciplinarity between different fields • Discuss and plan joint projects and grant applications • Stimulate collaborative field work and reciprocal help with field collection of research material • Inform on upcoming events, recent papers and other relevant material The NNB was created in 2011 and has been increasing every year, with previous meetings in Germany, USA and Colombia.

  • 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.

We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud.
