Without her guidance this study would not have been possible. I am especially indebted to Prof. Dr. Willibald Haffner as well, who recently passed away. His scientific knowledge and enthusiasm set a great example for me. I gratefully acknowledge Prof. Dr. Beck (Universität Bayreuth) and Prof. Dr. Knoke (Technische Universität München), and my colleagues and friends of the Institute of Geography (Friedrich-Alexander Universität Erlangen-Nürnberg) for sharing invaluable comments and motivation. Furthermore, I would like to express my sincere gratitude to those experts who unselfishly shared their knowledge with me, in particular to Dr. David Neill and Dr. Rainer Bussmann (Missouri Botanical Garden), Dr. Roman Krettek (Deutsche Gesellschaft für Mykologie), Dr. Jonathan Armbruster, (Auburn University, Alabama), Dr. Nathan K. Lujan (Texas A&M University), Dr. Jean Guffroy (Institut de Recherche pour le Développement, Orleans), Dr. Gabi Schachtel (Justus-Liebig Universität Giessen), and Lukas Wolfsbauer (Friedrich-Alexander Universität Erlangen-Nürnberg). I would also like to convey thanks to our counterparts Dr. Hidalgo and Dr. López Sandoval (Pontificia Universidad Católica del Ecuador, Quito) for a magnificent cooperation and to Virginia Lane for patiently revising the English of this dissertation and previous articles. I am also grateful to Stefan Adler, Judith Jaksch, and especially to Julia Kieslinger for their assistance during the draft of figures, the editing of text and photos, and their comprehension. I am grateful to collaborators of the Herbario Reinaldo Espinosa of the Universidad Nacional de Loja (Jhofre Aguirre, Bolivar Merino, Wilson Quizhpe, Holger Salas, Darío Veintimilla, Orlando Sánchez, Carlos Chimbo, and Néstor León) for their expertise and assistance with data collection and plant identification as well as for their logistical support. Deepest gratitude goes to Eduardo Tapia for his research assistance during field work and for making it so comfortable. My gratitude goes to the staff of the San Francisco Research Station, in particular to Abraham Pacheco, María Feijoó, Serafín Ramón, Rocío and Tati Aguirre, Polivio Ortega, and Pedro Paladines for, as Florian Werner remarked, “making the place damn close to home”. I am also grateful to all the researchers who shared with me their knowledge, expertise and time in Ecuador. This includes, among many others, Susanne Iost, Folkert Bauer, Dorothee Sandmann, Jutta Kapfer, Diana Avilés, Adriana Darquea, Jörg Zeilinger, Felix Matt, Franziska Volland-Voigt, Katrin Wolf, Rütger Rollenbeck, Sven Günter, Jürgen Homeier, Florian Werner, Alexandra Zach, Valentyna Krashevska, Kristin Roos, Glenda Mendieta, Baltazar Calvas, Patricio Crespo, and Adriana Tutillo. I wish also to convey my thanks to the whole staff of Nature & Culture International, especially to Nancy Romero, Renzo and Bruno Paladines, Trotsky Riera, and Felipe Serrano. I thank the inhabitants of the communities of Chumpias, El Cristal, El Retorno, El Tibio, Los Guabos, Napints, Sabanilla, Shaime and the owners of the visited fincas for their hospitality and generous participation in the interviews. i I kindly thank the German Research Foundation (DFG) for supporting this study in the frame of the projects proposed and conducted by Prof. Dr. Perdita Pohle: “Pflanzenkenntnisse und Pflanzennutzung bei den Shuar, Saraguro und Colonos in den tropischen Bergwaldregionen Südecuadors”, “Ethnoökologische Untersuchungen in den tropischen Bergwaldregionen Südecuadors - ein Beitrag zum Erhalt und zur nachhaltigen Nutzung von Biodiversität” (DFG Research Group FOR 402), and “Human ecological dimensions in sustainable utilization and conservation of tropical mountain forests” (DFG Research Group FOR 816). During the completion of the study I met people that influenced not only this research but also my life. I am especially indebted to the Pons family and to Ruth Espinosa and her family for making Ecuador so special. In addition, I offer my deepest gratitude to all those who supported me after the death of my father and especially during 2009, making the conclusion of this thesis possible. Thank you! I cannot forget two good friends who also passed away during these years. Tío Alberto, Roberto, también va por vosotros. Finally, I owe my deepest gratitude to my beloved family, who always has been there for me and has supported me unconditionally. Thank you for your understanding: ¡Gracias, mamá! ¡Por fin sabrás a qué me he dedicado todo este tiempo! ii CONTENT ACKNOWLEDGEMENTS i CONTENT OF FIGURES vii CONTENT OF TABLES xii CONTENT OF BOXES xv CONTENT OF ACRONYMS AND ABBREVIATIONS xvi GLOSSARY OF LOCAL TERMS xix 1 INTRODUCTION 1 1.1 GENERAL CONTEXT 1 1.2 REGIONAL CONFINEMENT: THE CASE OF SOUTHERN ECUADOR 5 1.3 AIM AND STRUCTURE OF THIS STUDY 8 2 CORE CONCEPTS: THE VALUE OF PLANT DIVERSITY, TRADITIONAL 10 ECOLOGICAL KNOWLEDGE AND TOOLS FOR BIODIVERSITY CONSERVATION 2.1 PLANT DIVERSITY AS A RESOURCE: THE USE VALUES OF BIOLOGICAL DIVERSITY 10 2.2 TRADITIONAL ECOLOGICAL KNOWLEDGE (TEK) 14 2.3 INSTRUMENTS TO CONSERVE TROPICAL FOREST AREAS THROUGH USE 15 2.3.1 Agroforestry, the use of non-timber forest products (NTFPs), and forest 16 restoration 2.3.2 Ecotourism 19 2.3.3 Payments for Environmental Services (PES) 20 2.3.4 Bioprospecting 25 3 THE AREA OF STUDY 28 3.1 SOUTHERN ECUADOR 28 3.1.1 The physical setting: topography, geology, and geomorphology 29 3.1.2 The climatic regimes 32 3.1.3 Vegetation in southern Ecuador 34 3.1.4 Nature reserves and other protected areas 35 3.1.4.1 The Biosphere Reserve Podocarpus-El Cóndor 36 3.1.4.2 National Parks of southern Ecuador 37 3.1.4.3 Protective Forests 39 3.1.4.4 Other reserves of importance 43 3.1.5 Ethnic groups in southern Ecuador 44 3.1.5.1 The Shuar of southern Ecuador 45 3.1.5.2 The Saraguros of southern Ecuador 48 3.1.5.3 The Mestizos of southern Ecuador 49 iii 3.1.6 Socio-economical structure of southern Ecuador 52 3.1.6.1 Population in southern Ecuador 52 3.1.6.2 Society and economy in southern Ecuador 52 3.2 STUDY SITES 57 3.2.1 The Shuar communities of Shaime (including Shamatak), Chumpias and Napints 58 3.2.2 The Saraguro communities of El Tibio and El Cristal 62 3.2.3 The Mestizo communities along the Upper Zamora 65 4 METHODS APPLIED 70 4.1 FIELD RESEARCH 70 4.1.1 Interview techniques 71 4.1.2 Sample plots and area estimation 73 4.1.3 Collection of plant specimens 74 4.2 DATA PROCESSING AND CLASSIFICATION 74 4.2.1 Plant processing and identification 74 4.2.2 Data compilation and format 75 4.2.3 Classification of ethnobotanical data 76 4.3 STATISTICAL DATA ANALYSES 78 4.3.1 Family Importance Value Index 78 4.3.2 Similarity and dissimilarity analyses 78 5 THE ETHNOBOTANICAL SURVEY 81 5.1 THE ETHNOBOTANICAL SURVEY, GENERAL FACTS 81 5.2 RESULTS OF THE SURVEY IN SHUAR COMMUNITIES 84 5.2.1 General aspects of Shuar plant use 84 5.2.2 The ethnobotanical use categories among the Shuar 87 5.2.2.1 Medicinal plants of the Shuar(MED) 88 5.2.2.2 Edible plants of the Shuar (FOO) 96 5.2.2.3 Plants used in construction by the Shuar (CON) 100 5.2.2.4 Fodder plants of the Shuar (FOD) 102 5.2.2.5 Plants used for fuel by the Shuar (FUE) 104 5.2.2.6 Ornamental plants of the Shuar (ORN) 106 5.2.2.7 Plants used to make tools and containers by the Shuar (T/C) 108 5.2.2.8 Plants used for hunting and fishing by the Shuar (H/F) 109 5.2.2.9 Plants used to make crafts by the Shuar (CRA) 110 5.2.2.10 Ritual and mythical plants of the Shuar (R/M) 111 5.2.2.11 Plants used in veterinary by the Shuar (VET) 112 5.2.2.12 Plants used by the Shuar to dye, to paint or to varnish (DPV) 113 5.2.2.13 Fiber plants of the Shuar (FIB) 114 5.2.2.14 Production of beetle larvae (BEE) 115 5.2.2.15 Shade trees of the Shuar(SHA) 115 5.2.2.16 Plants with other uses of the Shuar (OTH) 112 5.2.3 Other plants and fungi used by the Shuar of the Upper Nangaritza 117 5.3 RESULTS OF THE ETHNOBOTANICAL SURVEY AMONG THE SARAGUROS 121 5.3.1 The ethnobotany of the Saraguros 121 5.3.2 Use categories among the Saraguros 123 5.3.2.1 Edible plants of the Saraguros (FOO) 124 5.3.2.2 Medicinal plants of the Saraguros (MED) 127 5.3.2.3 Plants used in construction by the Saraguros (CON) 134 5.3.2.4 Ornamental plants of the Saraguros (ORN) 135 iv 5.3.2.5 Fodder plants of the Saraguros (FOD) 137 5.3.2.6 Plants used for fuel by the Saraguros (FUE) 138 5.3.2.7 Plants used as living fences by the Saraguros (FEN) 138 5.3.2.8 Plants used to make tools and containers by the Saraguros (T/C) 140 5.3.2.9 Shade trades of the Saraguros (SHA) 140 5.3.2.10 Plants with other uses of the Saraguros (OTH) 141

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

  • Vascular Flora and Vegetation Classification of the South Atlantic Coastal Plain Limestone Forest Association of Central Georgia
    VASCULAR FLORA AND VEGETATION CLASSIFICATION OF THE SOUTH ATLANTIC COASTAL PLAIN LIMESTONE FOREST ASSOCIATION OF CENTRAL GEORGIA by PATRICK SUMNER LYNCH (Under the Direction of J.L. Hamrick) ABSTRACT The South Atlantic Coastal Plain Limestone forest is a globally imperiled (G2) forest association known only from the upper Coastal Plain of central Georgia. These calcareous forest communities support diverse floristic assemblages unique among the Georgia Coastal Plain, but have not been subject to detailed floristic study. I conducted a comprehensive floristic inventory, multivariate community analyses and floristic quality assessments to document composition, elucidate community structure and underlying physiographic regimes, and assess habitat integrity for seven sites in Houston, Bleckley and Twiggs counties. Community analyses revealed twelve community types within two floristically defined domains corresponding to uplands and slopes, and bottomlands, respectively, and governed largely by moisture content and degree of inclination. Floristic quality assessments revealed varying degrees of floristic quality and habitat integrity corresponding primarily to local physiography and disturbance history. Floristic inventory recovered 339 vascular plant taxa representing 218 genera in 98 families, including 17 rare Georgia species.

  • Agave Americana and Furcraea Andina: Key Species to Andean Cultures in Ecuador
    Ethnobotany Agave americana and Furcraea andina: Key Species to Andean Cultures in Ecuador LUCÍA DE LA TORRE1*, IAN CUMMINS2, AND ELIOT LOGAN-HINES2 Botanical Sciences 96 (2): 246-266, 2018 Abstract Background: The rich Agaveae-based culture that exists in the Ecuadorian Andes is little known. Wild DOI: 10.17129/botsci.1813 and cultivated rosettes of Agave americana and Furcraea andina coexist in arid Andean landscapes. A. americana is considered an introduced species to Ecuador.

Agave americana, Furcraea andina March 12th, 2018 Species studied: Associated editor: Study site, dates: Ecuadorian Andes, 2016. Salvadro Arias Methods: Semi-structured interviews to Agaveae users (37) and a review of literature on ethnobotanical research conducted in Ecuador since the 18th century. Results: A. americana is more diversely and widely used than F. andina (124 vs 36 uses and 548 vs 140 use records, respectively). The versatility of A. americana lies in its mishki (sap extracted from its heart) which has multiple medicinal, edible and ceremonial applications. We found significant variation of its use patterns throughout the region. The main use of F. andina as a source of fiber is disappearing. Most productive initiatives involve A. americana (92 %, n = 53). Conclusion: The importance of A. americana in the Ecuadorian Andes is comparable to that of agaves in Mexico, but not to its importance in other Andean countries where it is used sporadically.

The lack of knowledge concerning Verhuellia is largely due to its restricted distribution, poorly known collection localities, limited availability in herbaria and absence in botanical gardens and lack of material suitable for molecular phylogenetic studies until recently. Because Verhuellia has some of the most reduced flowers in Piperales, the reconstruction of floral evolution which shows strong trends towards reduction in all lineages needs to be revised. † Methods Verhuellia is included in a molecular phylogenetic analysis of Piperales (trnT-trnL-trnF and trnK/matK), based on nearly 6000 aligned characters and more than 1400 potentially parsimony-informative sites which were partly generated for the present study. Character states for stamen and carpel number are mapped on the combined molecular tree to reconstruct the ancestral states.

  • Epilist 1.0: a Global Checklist of Vascular Epiphytes
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong.

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.
