Pollination Ecology Summary
Pollination Ecology Summary Prof. em. Klaus Ammann, Neuchâtel [email protected] June 2013 Ohne den Pollenübertragungs-Service blütenbesuchender Tiere könnten sich viele Blütenpanzen nicht geschlechtlich fortpanzen. Die komplexen und faszinierenden Bestäubungsvorgänge bei Blütenpanzen sind Ausdruck von Jahrmillionen von Selektionsvorgängen, verbunden mit Selbstorganisation der Lebewesen; eine Sicht, die auch Darwin schon unterstützte. Bei vielen zwischenartlichen Beziehungen haben sich zwei oder auch mehrere Arten in ihrer Entwicklung gegenseitig beeinusst. Man spricht hier von sogenannter Coevolution. Deutlich ist die Coevolution auch bei verschiedenen Bestäubungssystemen und -mechanismen, die von symbiontischer bis parasitischer Natur sein können. Die Art-Entstehung, die Vegetationsökologie und die Entstehung von Kulturpanzen sind eng damit verbunden Veranstalter: Naturforschende Gesellschaft Schaffhausen 1.

DOI:10.15835/nbha4229611 Cutting Type and IBA Treatment Duration Affect Teucrium fruticans Adventitious Root Quality Leo SABATINO, Fabio D’ANNA, Giovanni IAPICHINO* University of Palermo, Department of Agricultural and Forest Sciences, Viale delle Scienze, 90128, Palermo, Italy; [email protected]; [email protected]; [email protected] (*corresponding author) Abstract Root development of stem cuttings of Silver Germander (Teucrium fruticans) was investigated in relation to cutting type and indole-3-butyric acid (IBA) treatment. Terminal cuttings of a clone grown in Sicily were trimmed to three types: terminal cuttings with apex (TWA), terminal cuttings without apex (TWOA) or sub-terminal cuttings (ST). To verify the cutting response to exogenous auxin, cuttings were dipped to a 2.0 cm depth in a 0.5% indole-3-butyric acid solution for 0, 5 or 7 minutes. Overall percent survival was 97 to 98%. Rooting percent, root number and root length were affected by cutting type and indole-3-butyric acid treatment. In general, TWA cuttings demonstrated a higher capacity to form roots than cuttings without apex (TWOA and ST cuttings). In absence of indole-3-butyric acid treatment, TWA and ST cuttings gave higher rooting percentages than TWOA cuttings. Exposing cuttings to indole-3-butyric acid improved percent rooting, number of roots per cutting and root length. The best results in terms of rooting percentage and root number per cuttings were obtained with TWA cuttings in combination with 7 min indole-3-butyric acid basal dip. -
Towards Resolving Lamiales Relationships
Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales. -

This research reflects the data available at the time this evaluation was conducted. Summary This evaluation was conducted largely based on the parent species Lamium maculatum. This is due to the potential for any given cultivar to revert back to the parent type as it grows and/or hybridize with itself or neighboring varieties to produce hybrid seed, some of which is likely to very closely resemble the parent plant. Lamium maculatum can be aggressive in garden beds. It has escaped cultivation to a relatively small degree, but seems to be limited to disturbed sites, i.e. it may not have the capacity to compete successfully with native plants in natural areas in Minnesota. As a nettle, and a member of the mint family, it can spread aggressively via vegetative propagation. -

Disenchantment and Re-enchantment: Rhetorical Tension in the Siècle des Lumières A DISSERTATION SUBMITTED TO THE FACULTY OF THE UNIVERSITY OF MINNESOTA BY Sean P. Killackey IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Daniel Brewer DECEMBER 2020 © Sean P. Killackey, 2020 Acknowledgements First and foremost, I would like to thank the members of my committee, without whom none of this project would have seen the light of day. I am deeply grateful to Dan Brewer, Juliette Cherbuliez, Mary Franklin-Brown, and Michael Gaudio for their commitment and perseverance in seeing this dissertation project through to its completion. Before this dissertation even took shape, their courses and scholarship inspired new avenues of intellectual pursuit for me. I am particularly grateful for the many conversations at workshops, in offices and hallways, and after myriad speaker events with each of them during the development of ideas that would eventually coalesce into a dissertation project. I would like to express my deep and enduring gratitude to my advisor, Daniel Brewer, who read countless revisions with patience and tirelessly gave diplomatic and insightful feedback, challenging my assumptions and posing questions that lead me to more fruitful exploration and stronger writing. His intellectual guidance for this project over the long duration is a testament to his perseverance and his passion for critical inquiry into the literature and culture of the eighteenth century. I sincerely thank Juliette Cherbuliez for chairing my committee and for her advice on the importance of working with people who “ask great questions.” Her brilliant and challenging questions impacted my thinking on this project, perhaps more than she even knows. -

Doyle Professor of English, Science, Technology and Society, and Information Science and Technology Nancy Locke Associate Professor of Art History Craig Zabel Associate Professor of Art History Head of the Department of Art History *Signatures are on file in the Graduate School. ii Abstract This dissertation examines the ways that five contemporary artists—Mark Dion (b. 1961), Fred Tomaselli (b. 1956), Walton Ford (b. 1960), Roxy Paine (b. 1966) and Cy Twombly (b. 1928)—have adopted the visual traditions and theoretical formulations of historical natural history to explore longstanding relationships between “nature” and “culture” and begin new dialogues about emerging paradigms, wherein plants, animals and fungi engage in ecologically-conscious dialogues. Using motifs such as curiosity cabinets and systems of taxonomy, these artists demonstrate a growing interest in the paradigms of natural history. For these practitioners natural history operates within the realm of history, memory and mythology, inspiring them to make works that examine a scientific paradigm long thought to be obsolete. This study, which itself takes on the form of a curiosity cabinet, identifies three points of consonance among these artists. -
A Guide to Some of the Shrubs Currently
305 Syringa vulgaris (lilac) The name suggested needs to be checked as it is quite likely this is a hybrid or cultivar at the very least, but S. vulgaris at least in part is likely. It is a deciduous shrub that has gone in and out of fashion over the years. It is deciduous and has spectacular flowering from mid spring for about a month and then blends back into the shrubbery. This example is in the Betula Border, about midway and can be seen at its best around early October. There are now no other lilacs on campus. I suspect this one was planted early on, possibly in the late 1950’s or early 1960’s. A large spreading shrub of around 4metres in height and spread. Both of the above photos were taken on 15th October 2008. 306 Telopea oreades This is an evergreen shrub at the south western end of the pond at the Amenity Area. It has been relatively slow growing in this site, planted during the 1990’s and is currently about 3m in height. To the best of my knowledge, this plant has not flowered yet. It appears perfectly hardy in the relatively open site it occupies. An upright growing evergreen shrub native to south east Australia Leaves are simple, alternately arranged, oblanceolate, petiolate, mostly entire. 307 Teucrium chamaedrys (wall germander) There are two places on campus where these low growing sub-shrubs are growing. One is on the east side of the Wine Lab. near the north west corner of the Horticultural Teaching lab., the other is opposite the south west side of the southern entrance to the Commerce Building near Farm Road at the base of a sycamore tree. -
Morphological, Anatomical and Cytological Studies on Endemic Lamium Pisidicum
Pak. J. Bot ., 45(1): 73-85, 2013. MORPHOLOGICAL, ANATOMICAL AND CYTOLOGICAL STUDIES ON ENDEMIC LAMIUM PISIDICUM PELĐN BARAN 1* AND CANAN ÖZDEMĐR 2 1Uşak University, Faculty of Science and Art, Department of Biology, 1 Eylül Campus, D2Academic Block, Uşak 64200-Turkey; 2Celal Bayar University, Faculty of Art and Science, Department of Biology, Muradiye Campus, Muradiye-Manisa 45140-Turkey *Corresponding author’s e-mail: [email protected] Abstract Morphological and anatomical features of endemic Lamium pisidicum R. Mill (Lamiaceae) were studied. L. pisidicum is a perennial with a taproot system. The stem is ascending to erect in position and clearly quadrangular in shape. The leaves are ovate to broadly ovate or rarely reniform in shape. Verticillasters are 2-14 flowered. The corolla is pinkish-purple to mauve and the upper lip is deeply bifid and the tube is without annulus. The stigma is bifid. The stamens are didynamus. Anatomically, spring and autumn woods are distinguishable in the root structure of the perennial taxon. There is a well- developed collenchymatous layer at the corners of the stem and a pith hollow in the centre. In the petiole cross-section, 1-2 layered collenchyma layer is located at the corners while 3 central vascular bundles are located in the middle and 1 vascular bundle at the petiolar wings. The leaf is bifacial. Each anther is of two thecae and each theca is of 2 pollen sacs. Pollen type is trizonocolpate and pollen shape is spheroidal. The cross-section of seed is triangular. Glandular hairs distributed on the plant species are classified into 2 main types, peltate and capitate.
