Pollination Ecology and Demography of a Deceptive Orchid POLLINATION ECOLOGY AND DEMOGRAPHY OF A DECEPTIVE ORCHID Ryan P. Walsh A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY August 2013 Committee: Helen Michaels, Advisor Timothy J. Murnen Graduate Faculty Representative Karen Root Moira van Staaden Randy Mitchell ii ABSTRACT Helen Michaels, Advisor This dissertation is focused on three main questions addressing the reproductive and demographic effects of pollen limitation, seed predation and deceit pollination in the food deceptive orchid Cypripedium candidum. We conducted two hand pollination field experiments to quantify pollen limitation and inbreeding. Both studies showed strong pollen limitation, with supplemental hand pollinations increasing fruit set in 2009 by 41% and 2011 by 30-35%. Taller plants in the study were more likely to be pollinated, while all other size variables did not influence pollination or fruit set. The 2011 study demonstrated a reduction in seed mass in selfed capsules by 63%. We found high levels of fruit predation in 2009 with 73% of the fruit experiencing pre-dispersal seed predation resulting in an 89% reduction in seed mass. Of the size variables analyzed, shorter plants were more likely to be attacked by weevils. In a nectar addition study we manipulated plants to provide a nectar reward, dyed their pollinia for tracking and compared their reproduction against control plants with no reward. Nectar reward, which had no effect on fruit production, however did result in a nearly threefold increase in selfing. Approximately 26% of non-rewarding C. candidum pollination events result in selfing, while the addition of nectar increased selfing to 78%. Selfed seed capsules had a decreased seed mass as demonstrated in the previous experiment. Finally, we conducted a four year demographic study and produced matrix models that estimated the population growth rate at λ = 1.01 under an average of 22% pre-dispersal seed predation. Elasticity values of the models indicated the stasis and growth of one-flowered individuals to be the most important factors to the population growth iii rate. A model simulating the effects of nectar addition with the average rate of seed predation resulted in λ = 0.99. These studies demonstrate the complex reproductive dynamics of deceptive plants and provide evidence suggesting the evolution of deceit pollination is driven by multiple factors, including predation and decreased fecundity from selfing. iv ACKNOWLEDGMENTS I would like to thank my advisor, Dr. Helen Michaels for mentoring me through both undergraduate and graduate school and dragging me begrudgingly into the world of plant pollinator interactions.

  • Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

  • Taxonomic Notes on Anacamptis Pyramidalis Var. Urvilleana (Orchidaceae), a Good Endemic Orchid from Malta
    J. Eur. Orch. 48 (1): 19 – 28. 2016. Stephen Mifsud Taxonomic notes on Anacamptis pyramidalis var. urvilleana (Orchidaceae), a good endemic orchid from Malta Keywords Orchidaceae; Anacamptis urvilleana; Anacamptis pyramidalis; Anacamptis pyramidalis var. urvilleana; Maltese endemics; Flora of Malta; Central Mediterranean region. Summary Mifsud S. (2016): Taxonomic notes on Anacamptis pyramidalis var. urvilleana (Orchidaceae), a good endemic orchid from Malta.- J. Eur. Orch. 48 (1): 19-28. In several global plant species databases the Maltese-endemic Anacamptis urvilleana is considered as a synonym of A. pyramidalis, hence reflecting the belief of some European authors. A number of morphological differences and phenology differentiate the Maltese pyramidical orchid from A. pyramidalis. As a result, it is suggested to maintain the identity of this orchid as A. pyramidalis var. urvilleana which merits conservation treatments different from the widely distributed A. pyramidalis s. str. Zusammenfassung Mifsud S. (2016): Taxonomische Anmerkungen zu Anacamptis pyramidalis var. urvilleana (Orchidaceae), eine gute endemische Orchidee von Malta.- J. Eur. Orch. 48 (1): 19-28. In verschiedenen weltweiten Datenbanken botanischer Namen, die auch die Meinung einiger europäischer Autoren wiedergeben, wird der maltesische Endemit Anacamptis urvilleana als Synonym von A. pyramidalis geführt. Die maltesische Pyramiden-Hundswurz unterscheidet sich jedoch sowohl in einer Reihe von morphologischen Merkmalen als auch phenologisch von A. pyramidalis. Auf dieser Grundlage wird vorgeschlagen, diese Orchidee als A. pyramidalis var. urvilleana zu führen. Zu ihrem Schutz sind andere Erhaltungsmaßnahmen erforderlich als für die weitverbreitete A. pyramidalis s. str. Journal Europäischer Orchideen 48 (1): 2016. 19 1.

  • Watsonia 14 (1982), 79-100
    Walsonia , 14, 79-100 (\982) 79 Book Reviews Flowers of Greece and the Balkans. A field guide. Oleg Polunin. Pp. xv+592 including 62 pages of line drawings and 21 maps, with 80 colour plates. Oxford University Press, Oxford. 1980. Price £40.00 (ISBN 0-19- 217-6269). This latest of Oleg Polunin's Field guides to the European flora presents a concise, but by no means superficial, picture of the flowering plants and conifers of the Balkan peninsula. The area that is covers takes in the whole of Greece (including the East Aegean Islands, excluded from Flora Europaea), Turkey-in-Europe, Albania, Bulgaria, Jugoslavia as far north as the River Sava, and the small portion of Romania that lies south and east of the River Danube. The author has condensed his account of the rich and varied flora of the region, together with the associated mass of published material, into a form that is attractive, comprehensible and useful to the amateur botanist. A book of this type has been badly needed, as the available floristic texts on the Balkans tend to be over 50 years old, scarce, extremely expensive and written in a foreign language, often Latin. However, the most significant attribute of this book is not that it gives access to diffuse and obscure information, but that it provides a radical alternative to popular botanical accounts of Greece which emphasize the lowland spring flora, notably the orchids and other petaloid monocots. Based on the author's many years of botanical experience and extensive travel in the region, Flowers of Greece and the Balkans demonstrates the wide range of flora and vegetation that the amateur botanist can expect to see in the Balkan peninsula.

Phylogenetic relationships within this tribe have been studied previously using only nuclear ribosomal DNA (nuclear ribosomal internal transcribed spacer, nrITS). However, different parts of the phylogenetic tree in these analyses were weakly supported, and integrating information from different plant genomes is clearly necessary in orchids, where reticulate evolution events are putatively common. The aims of this study were to: (1) obtain a well-supported and dated phylogenetic hypothesis for tribe Orchideae, (ii) assess appropriateness of recent nomenclatural changes in this tribe in the last decade, (3) detect possible examples of reticulate evolution and (4) analyse in a temporal context evolutionary trends for subtribe Orchidinae with special emphasis on pollination systems.

  • Fungal Diversity Driven by Bark Features Affects Phorophyte
    www.nature.com/scientificreports OPEN Fungal diversity driven by bark features afects phorophyte preference in epiphytic orchids from southern China Lorenzo Pecoraro1*, Hanne N. Rasmussen2, Sofa I. F. Gomes3, Xiao Wang1, Vincent S. F. T. Merckx3, Lei Cai4 & Finn N. Rasmussen5 Epiphytic orchids exhibit varying degrees of phorophyte tree specifcity. We performed a pilot study to investigate why epiphytic orchids prefer or avoid certain trees. We selected two orchid species, Panisea unifora and Bulbophyllum odoratissimum co-occurring in a forest habitat in southern China, where they showed a specifc association with Quercus yiwuensis and Pistacia weinmannifolia trees, respectively. We analysed a number of environmental factors potentially infuencing the relationship between orchids and trees. Diference in bark features, such as water holding capacity and pH were recorded between Q. yiwuensis and P. weinmannifolia, which could infuence both orchid seed germination and fungal diversity on the two phorophytes. Morphological and molecular culture-based methods, combined with metabarcoding analyses, were used to assess fungal communities associated with studied orchids and trees. A total of 162 fungal species in 74 genera were isolated from bark samples. Only two genera, Acremonium and Verticillium, were shared by the two phorophyte species. Metabarcoding analysis confrmed the presence of signifcantly diferent fungal communities on the investigated tree and orchid species, with considerable similarity between each orchid species and its host tree, suggesting that the orchid-host tree association is infuenced by the fungal communities of the host tree bark. Epiphytism is one of the most common examples of commensalism occurring in terrestrial environments, which provides advantages, such as less competition and increased access to light, protection from terrestrial herbivores, and better fower exposure to pollinators and seed dispersal 1,2.

GIGORD 1Department of Biological Sciences, University of Exeter, Hatherly Laboratories, Prince of Wales Road, Exeter EX4 4PS, UK 2Department of Ecology and Evolution, Biology Building, University of Lausanne, Lausanne, CH-1015, Switzerland Abstract. Among rewardless orchids, pollinator sampling behavior has been suggested to drive a positive relationship between population phenotypic variability and absolute reproductive success, and hence population fitness. We tested this hypothesis by constructing experimental arrays using the rewardless orchid Dactylorhiza sambucina, which is dimorphic for corolla color. We found no evidence that polymorphic arrays had higher mean reproductive success than monomorphic arrays for pollinia removal, pollen deposition, or fruit set. For pollinia removal, monomorphic yellow arrays had significantly greater reproductive success, and monomorphic red the least. A tendency for yellow arrays to have higher pollen deposition was also found. We argue that differential population fitness was most likely to reflect differential numbers of pollinators attracted to arrays, through preferential long-distance attraction to arrays with yellow inflorescences. Correlative studies of absolute reproductive success in 52 populations of D. sambucina supported our experimental results. To our knowledge this is the first study to suggest that attraction of a greater number of pollinators to rewardless orchids may be of greater functional importance to population fitness, and thus ecology and conservation, than are the behavioral sequences of individual pollinators.

  • Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local Study)
    plants Article Phytogeographical Analysis and Ecological Factors of the Distribution of Orchidaceae Taxa in the Western Carpathians (Local study) Lukáš Wittlinger and Lucia Petrikoviˇcová * Department of Geography and Regional Development, Faculty of Natural Sciences, Constantine the Philosopher University in Nitra, 94974 Nitra, Slovakia; [email protected] * Correspondence: [email protected]; Tel.: +421-907-3441-04 Abstract: In the years 2018–2020, we carried out large-scale mapping in the Western Carpathians with a focus on determining the biodiversity of taxa of the family Orchidaceae using field biogeographical research. We evaluated the research using phytogeographic analysis with an emphasis on selected ecological environmental factors (substrate: ecological land unit value, soil reaction (pH), terrain: slope (◦), flow and hydrogeological productivity (m2.s−1) and average annual amounts of global radiation (kWh.m–2). A total of 19 species were found in the area, of which the majority were Cephalenthera longifolia, Cephalenthera damasonium and Anacamptis morio. Rare findings included Epipactis muelleri, Epipactis leptochila and Limodorum abortivum. We determined the ecological demands of the abiotic environment of individual species by means of a functional analysis of communities. The research confirmed that most of the orchids that were studied occurred in acidified, calcified and basophil locations. From the location of the distribution of individual populations, it is clear that they are generally arranged compactly and occasionally scattered, which results in ecological and environmental diversity. During the research, we identified 129 localities with the occurrence of Citation: Wittlinger, L.; Petrikoviˇcová, L. Phytogeographical Analysis and 19 species and subspecies of orchids. We identify the main factors that threaten them and propose Ecological Factors of the Distribution specific measures to protect vulnerable populations.

    Oklahoma Native Plant Record 39 Volume 1, Number 1, December 2001 Native Orchids of Oklahoma Dr. Lawrence K. Magrath Curator-USAO (OCLA) Herbarium Chickasha, OK 73018-5358 As of the publication of this paper Oklahoma is known to have orchids of 33 species in 18 genera, which compares to 20 species and 11 genera reported by Waterfall (1969). Four of the 33 species are possibly extinct in the state based on current survey work. The greatest concentration of orchid species is in the southeastern corner of the state (Atoka, Bryan, Choctaw, LeFlore, McCurtain and Pushmataha Counties). INTRODUCTION Since the time of Confucius (551-479 BCE) who mentioned lan in his writings, "acquaintance with The family Orchidaceae is the largest of the good men was like entering a room full of lan or families of flowering plants with somewhere between fragrant orchids" (Withner, 1959), orchids have been 25,000 and 35,000 species, with new species important in many facets of Chinese life including continually being described. There are also literature, painting, horticulture, and not least, numerous natural and artificial hybrids. The only medicine". They are mentioned in the materia place where orchids are not known to occur is medica, “Sheng nung pen ts'ao ching”, tracing back Antarctica. to the legendary emperor Sheng Nung (ca. 28th Orchids fascinate us because of the century BCE). The term "lan hua" in early Chinese seemingly infinite combinations of colors and forms records refers to species of the genus Cymbidium that are found in orchid flowers from the Arctic to (Withner, 1959), most likely Cymbidium the tropical rain forests.

Summary Klahr, B. (2005): The orchids of Formentera.- Jour. Eur. Orch. 37 (4): 501 XXX. A short review of history and geography of Formentera is given; aspects of flora and fauna of a south mediterranean Island, survival of plants in a half-arid zone without any wells or fresh ground water. As the most southern Island of the Pityuses, Formentera belongs climatically more to Africa than to Europe. It is a very rocky eroded Island after having had a long period without agriculture. Endemic species in flora and fauna are mentioned. Wild Orchids are growing on this small Island mainly in the higher regions of the plateau La Mola and Cap de Barbaria. There is not as much pastureland as in other mediterranean countries. Ophrys and Orchis predominate.. Most areas of Formentera were explored during the whole year, also difficult to reach regions like “Torrentes” (Canyons). The period of my observation is 2002 - 2005. The Orchids are endangered as a result of the reinforced agriculture and chemical fertilizing, subsidized by the EU, and by increasing building activities. Centuries fallow agricultural land that makes very interesting biotopes will be destroyed. The orchids of Formentera are bibliographically quoted; the results are to be supplemented with four new found species and new sites.
