Project Report THE APPLICATION OF PHYTOLITH AND STARCH GRAIN ANALYSIS TO UNDERSTANDING FORMATIVE PERIOD SUBSISTENCE, RITUAL, AND TRADE ON THE TARACO PENINSULA, HIGHLAND BOLIVIA ___________________________________________________________________ A Thesis Presented to the Faculty of the Graduate School University of Missouri, Columbia ___________________________________________________________________ In Partial Fulfillment Of the Requirements for the Degree Master of Arts ___________________________________________________________________ By AMANDA LEE LOGAN Supervisor: Dr. Deborah M. Pearsall AUGUST 2006 Dedicated to the memory of my grandmother Joanne Marie Higgins 1940-2005 ACKNOWLEDGEMENTS There are a great number of people who have helped in this process in passing or in long, detailed conversations, and everything in between. First and foremost, many thanks to my advisor, Debby Pearsall, for creative and inspired guidance, and for taking the time to talk over everything from the smallest detail to the biggest challenges. Debby introduced me to the world of phytoliths, and then to the wonders of starch grains, and encouraged me to find and pursue the issues that drive me. My committee has been very helpful and patient, and made my oral exams and defense far more enjoyable then expected—Dr. Christine Hastorf, Dr. Bob Benfer, and Dr. Randy Miles. Dr. Benfer was crucial in helping me sort through the statistical applications. I also benefited tremendously from conversations with and advice from my cohorts in the MU Paleoethnobotany lab, or as we are better known, the “Pearsall Youth”— Neil Duncan, Shawn Collins, Meghann O’Brien, Tom Hart, and Nicole Little. Dr. Karol Chandler-Ezell gave me great advice on calcium oxalate and chemical processing. Dr. Todd VanPool graciously provided much needed advice on the statistical applications. Being a part of the Taraco Archaeological Project has brought many good ideas to mind, taught me a lot about Bolivian and Andean archaeology, and has truly been a pleasure. Many thanks to the whole TAP team, especially Dr. Christine Hastorf, Maria Bruno, Jose Capriles, Dr. Kate Moore, Bill Whitehead, Dr. Matt Bandy, and Facundo Llusco. Christine Hastorf has waited patiently for good results, provided the most rigorously collected samples I could hope for, and most importantly, showed interest at every level of my project. She provided me with coca samples in 2004, washed the artifact residues in the 2005 field season, and provided me with a book on Bolivian ii grasses. Maria Bruno was instrumental in teaching me many things ethnobotanical in Bolivia, let me take samples from her voucher specimens and from her field soil collection, as well as providing much needed information and advice throughout the course of this project. Finally, the comparative phytolith work on Andean plants conducted by Alejandra Korstanje (Universidad Nacional de Tucumán) and loaned to the MU Paleoethnobotany lab was extremely valuable for my purposes. As always, thanks to Shannon King for support in every way and on every level, from the first applications to the final draft. Many thanks go to my family, especially my father, John Logan, and my aunt, Donna Logan, for encouraging me to get this far and to keep going. Branka Hrvoj listened to a lot of phytolith talk, and helped me stay positive. Special thanks to Dr. Catherine D’Andrea (Simon Fraser University) for piquing and developing my interest in archaeobotany, getting me here in the first place, and supporting my pursuits ever since. Discussions with many of the participants in the 2005 Chacmool Archaeological Conference, especially Sonia Quon and Dr. Linda Perry, were helpful in disentangling the complexities of this data. Most of the comparative plant samples used in this study were collected at the Missouri Botanical Garden, thanks to Dr. Jim Solomon. Some grass and sedge species were collected at the University of Missouri Columbia Herbarium, courtesy of Dr. Robin Kennedy. Thanks also to Dr.R.L. Lyman who kindly gave the thesis the final once-over. This research was supported by an NSF grant to Christine A. Hastorf, for this I am truly grateful; this would have been only half the project otherwise. I also received additional support through research assistantships from NSF grants to Deborah M. Pearsall. iii TABLE OF CONTENTS Acknowledgements............................................................................................................. ii List of Tables

    A REVISION OF TRISETUM Victor L. Finot,' Paul M. Peterson,3 (POACEAE: POOIDEAE: Fernando 0 Zuloaga,* Robert J. v sorene, and Oscar Mattnei AVENINAE) IN SOUTH AMERICA1 ABSTRACT A taxonomic treatment of Trisetum Pers. for South America, is given. Eighteen species and six varieties of Trisetum are recognized in South America. Chile (14 species, 3 varieties) and Argentina (12 species, 5 varieties) have the greatest number of taxa in the genus. Two varieties, T. barbinode var. sclerophyllum and T longiglume var. glabratum, are endemic to Argentina, whereas T. mattheii and T nancaguense are known only from Chile. Trisetum andinum is endemic to Ecuador, T. macbridei is endemic to Peru, and T. foliosum is endemic to Venezuela. A total of four species are found in Ecuador and Peru, and there are two species in Venezuela and Colombia. The following new species are described and illustrated: Trisetum mattheii Finot and T nancaguense Finot, from Chile, and T pyramidatum Louis- Marie ex Finot, from Chile and Argentina. The following two new combinations are made: T barbinode var. sclerophyllum (Hack, ex Stuck.) Finot and T. spicatum var. cumingii (Nees ex Steud.) Finot. A key for distinguishing the species and varieties of Trisetum in South America is given. The names Koeleria cumingii Nees ex Steud., Trisetum sect. Anaulacoa Louis-Marie, Trisetum sect.

We tested this Climatic debt hypothesis in tropical alpine environments above 4700 m a.s.l. (Central Andes) and we explored the underlying Chronosequence mechanisms at work by using four sites gradually deglaciated since the acceleration of warming in the late 1970’s.

  • Diversidad De Plantas Y Vegetación Del Páramo Andino
    Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1).

The two most important species of this region are F. dolichophylla J. Presl (known as “chilliwa”) and F. orthophylla Pilg (known as “iru ichu”). This research aimed to investigate the phylogenetic relationships within the Festuca genus from the highlands of Bolivia, to evaluate the genetic diversity using EST-SSR markers and to assess the nutritional value for its use in breeding and conservation. The phylogenetic analysis, which was based on sequences derived from nuclear (ITS, CEN, Acc1) and chloroplast DNA (matK) regions, revealed that the Bolivian Festuca species derived from a common ancestor of the fine-leaved lineage of the Festuca sub-genus.

  • NEARBY, a Computer Program for Phytogeographic Analysis Using Georeferenced Specimen Data
    NEARBY, a Computer Program for Phytogeographic Analysis Using Georeferenced Specimen Data Daryl L. Lafferty & Leslie R. Landrum Natural History Collections, School of Life Sciences Arizona State University, Tempe, Arizona 85287-4108, U.S.A. Author emails: [email protected]; [email protected] ABSTRACT: We present a computer program, NEARBY, that uses databases of georeferenced specimens to explore plant and lichen distributions and co-occurrences. NEARBY utilizes three SYMBIOTA databases: SEINet (mainly vascular plants of North America), NEOTROPICAL (mainly vascular plants of neotropical and temperate South America), and CNALH (lichens, mainly of the western hemisphere). A Primary species is entered into the program and a geographic area is defined. Parameters are chosen that limit the search for specimens of Secondary species that have been collected near the Primary species. The output consists of: a summary of the input data and how it was modified for the search; a list of the most commonly found Secondary species that occur with the Primary species in the defined area; and additional data and links to images for each species. These data can be manipulated in various ways or copied into another program for analysis. NEARBY includes a map option that allows the user to compare distributions of the Primary and Secondary species. An example of a search is discussed in detail and case studies that illustrate the use of the program are provided. An appendix describing the program function is provided. INTRODUCTION The distribution of organisms across landscapes, continents, and the globe have long been an interest of biologists, including Humboldt and Bonpland (1807; English translation 2009), Hooker (1853), and Darwin (1859; reprint 1985).
