Diversitatea biologică asigură funcţionalitatea optimă a ecosistemelor naturale, existenţa şi dezvoltarea biosferei în general. Datorită intensifi cării impactului antropic asupra biosferei, numărul speciilor de plante periclitate sporeşte din an în an, se reduc simţitor te- renurile acoperite cu vegetaţie naturală, ariile naturale protejate nu-şi pot îndeplini funcţia de stabilizare a sistemelor ecologice. Realizarea Planului de acţiuni în cadrul Convenţiei cu privire la diversitatea biologică (Rio de Janeiro, 1992), necesită efi cientizarea semnifi cativă a măsurilor în vederea conservării biodiversităţii şi habitatelor naturale, utilizării raţionale a resur- selor biologice, restabilirii ecosistemelor degradate şi speciilor periclitate. Sperăm că rezultatele ştiinţifi ce expuse în materialele simpozionului vor servi ca sursă de informare şi promovare a cunoştinţelor în societate, contribuind astfel la sporirea nivelului de educaţie a societăţii.

Langer Institute of Pharmacognosy, University of Vienna Center of Pharmacy, Althanstrasse 14, A - 1090 Vienna, Austria Improved descriptions and detailed drawings of the most important anatomical characters of the roots of Echinacea purpurea (L.) MOENCH,E. angustifolia DC., E. pallida (NuTT.) NUTT.,and of Parfhenium integrifolium L. are presented. The anatomy of the rhizome of E. purpurea, which was detected in commercial samples, and of the root of E. atrorubens NUTT., another known adulteration for pharmaceutically used Echinacea-species, is documented for the first time. The possibilities and limitations of the identification by means of microscopy are discussed. The anatomical differences between the roots of E. angustifolia, E. pallida and E. atrorubens are not sufficient for differentiation, however, root and rhizome of E. purpurea and the root of Parthenium integrifolium appear well characterized. Because of the highly similar anatomy the microscopic proof of identity and purity of crude drugs of Echinacea must be done with uncomminuted material and the examination of cross sections. (Keywords: Echinacea angustifolia, Echinacea atrorubens, Echinacea pallida, Echinacea purpurea, Parthenium integrifolium, Asteraceae, microscopy, anatomy, identification) 1. Introduction The first, and for a long period only, detailed anatomical descriptions of the underground parts of Echinacea were published at the beginning of the last century', '. Due to later changes in the taxonomy within the genus Echinacea, unfortunately the plant sources for these descriptions remain unclear. The increasing interest in Echinacea and the adulterations that had been observed frequently caused Heubl et aL3 in the late eighties to examine the roots of E.

    GLOBAL RELATIONSHIPS BETWEEN PLANT FUNCTIONAL TRAITS AND ENVIRONMENT IN GRASSLANDS EMMA JARDINE A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy The University of Sheffield Department of Animal and Plant Sciences Submission Date July 2017 ACKNOWLEDGMENTS First of all I am enormously thankful to Colin Osborne and Gavin Thomas for giving me the opportunity to undertake the research presented in this thesis. I really appreciate all their invaluable support, guidance and advice. They have helped me to grow in knowledge, skills and confidence and for this I am extremely grateful. I would like to thank the students and post docs in both the Osborne and Christin lab groups for their help, presentations and cake baking. In particular Marjorie Lundgren for teaching me to use the Licor, for insightful discussions and general support. Also Kimberly Simpson for all her firey contributions and Ruth Wade for her moral support and employment. Thanks goes to Dave Simpson, Maria Varontsova and Martin Xanthos for allowing me to work in the herbarium at the Royal Botanic Gardens Kew, for letting me destructively harvest from the specimens and taking me on a worldwide tour of grasses. I would also like to thank Caroline Lehman for her map, her useful comments and advice and also Elisabeth Forrestel and Gareth Hempson for their contributions. I would like to thank Brad Ripley for all of his help and time whilst I was in South Africa. Karmi Du Plessis and her family and Lavinia Perumal for their South African friendliness, warmth and generosity and also Sean Devonport for sharing all the much needed teas and dub.
