By Charles Daubeny, F.R.S., &c., Professor of Botany, Oxford.* The eruption to which I wish to direct the attention of this Section has already been described by several eye-witnesses, two of whom, namely, Professor Palmieri and M. Pierre de Tchihatscheff, of London, have communicated to the Geolo- gical Society brief reports of the most striking physical pheno- mena attending it, such as the outburst of springs of acidulous and hot water, and the upheaval of the ground at Torre del Greco, to the height of 1.12 metre above the level of the Mediterranean. M. Claire Deville, also, a French savant who has made the gases evolved from volcanos his particular study, was sum- moned from Paris immediately upon the commencement of the eruption, and arrived in time, if not to witness the outbreak, at least to collect and examine the emanations which were its immediate consequences. All, therefore, I shall attempt to do in this brief communi- cation, is to point out to you the facts of the greatest novelty which others have anticipated me in recording, and to con- sider the bearing Avhich they may have on the general theory of Volcanos. Vesuvius, within the last few years, has entered apparently upon a new phase of volcanic operations. At former periods * Read at a Meeting of the British Association for the Advancement of Science, Friday, October 3d, 1862. NEW SERIES VOL. XVII. NO. I. JAN. 1863. A 2 Professor Daubeny on the Eruption of Vesuvius in 1861. its eruptions occurred at distant intervals apart, but were distinguished by their violence and magnitude. Thus, only 9 eruptions are recorded as having taken place between the commencement of the Christian era and of the beginning of the seventeenth century ; in the course the latter, viz., from 1631 to 1694, there occurred 4; in the nineteenth, eighteenth century 22 ; and in the first half of the viz., from 1802 to 1850, no less than 17. Thus, even allowing for the greater imperfection of records during the Middle Ages, which might have prevented a few of the earlier eruptions from having been handed down to us, there seems to be sufficient evidence of a gradually increasing frequency in the volcanic outbreaks, as we approach the pre- sent time. As to the gfeater violence of the earlier eruptions, there seems sufficient proof of it in the accounts given us by ancient writers of the fearful outbreak of a.d. 79, by which Pompeii and Herculaneum were overwhelmed; of that of 204, described by Dion Cassius and Galen, in which the noises produced by the ejection of matters from the crater were loud enough to be heard at Capua ; of the third, in 472, which is said by Pro- copius to have spread alarm even at Constantinople ; and of that great one in 1631, which, after a pause of one hundred and thirty-one years, during which the crater had been covered with shrubs and rich verdure, overspread with lava the greater part of the villages lying at its foot on the side of the Bay of Naples, and occasioned the death of 4000 persons.

    NETWORKING FOR DIVERSITY Annual Report 2017 – 2019 2017 – BGBM BGBM Annual Report 2017 – 2019 Cover image: Research into global biodiversity and its significance for humanity is impossible without networks. The topic of networking can be understood in different ways: in the natural world, with the life processes within an organism – visible in the network of the veins of a leaf or in the genetic diversity in populations of plants – networking takes place by means of pollen, via pollinators or the wind. In the world of research, individual objects, such as a particular plant, are networked with the data obtained from them. Networking is also crucial if this data is to be effective as a knowledge base for solving global issues of the future: collaboration between scientific experts within and across disciplines and with stakeholders at regional, national and international level.

  • Palatability of Plants to Camels (DBIRD NT)
    Technote No. 116 June 2003 Agdex No: 468/62 ISSN No: 0158-2755 The Palatability of Central Australian Plant Species to Camels Dr B. Dorges, Dr J. Heucke, Central Australian Camel Industry Association and R. Dance, Pastoral Division, Alice Springs BACKGROUND About 600,000 camels (Camelus dromedarius) are believed to inhabit the arid centre of Australia, mainly in South Australia, Western Australia and the Northern Territory. Most of these camels are feral. A small camel industry has developed, which harvests selected animals for domestic and export markets, primarily for meat. Camels can eat more than 80% of the common plant species found in Central Australia. Some plant species are actively sought by camels and may need to be protected. METHOD Observations of grazing preferences by camels were made periodically for up to 12 years on five cattle stations in Central Australia. Where camels were accustomed to the presence of humans, it was possible to observe their grazing preferences from a few metres. Radio transmitters were fitted on some camels for easy detection and observation at any time. These evaluations were used to establish a diet preference or palatability index for observed food plants. Table 1. Palatability index for camels Index Interpretation 1 only eaten when nothing else is available 2 rarely eaten 3 common food plant 4 main food plant at times 5 preferred food plant 6 highly preferred food plant 7 could be killed by camel browsing More information can be obtained from the web site of the Central Australian Camel Industry Association http://www.camelsaust.com.au 2 RESULTS Table 2.

Although their toxicity has been known for a long time, PA containing plants are still in use in many traditional medicines. Traditional healing systems have become of increasing interest as many people believe that they can be used without any risk and side effects. This also applies to the traditional medicine of Madagascar and the Mascarene island (Mauritius, Réunion, Rodriguez). Recent literature reports have recommended this traditional medicine because of its good efficacy and pharmacological properties. However, several plants are listed there which have already been described to contain toxic PAs or are suspected of containing them. 1. Introduction play a growing role in the treatment of diseases in the form of self-medication. Pyrrolizidine alkaloids (PAs)are naturally occurring compounds In addition, increased tourism has made it possible that people which are contained in about 3% of all flowering plants (Bull come into contact with different traditional healing systems all et al.

    Snow White and Rose Red: Studies on the contrasting evolutionary trajectories of the genera Leucanthemum Mill. and Rhodanthemum B.H.Wilcox & al. (Compositae, Anthemideae) DISSERTATION ZUR ERLANGUNG DES DOKTORGRADES DER NATURWISSENSCHAFTEN (DR. RER. NAT.) DER FAKULTÄT FÜR BIOLOGIE UND VORKLINISCHE MEDIZIN DER UNIVERSITÄT REGENSBURG vorgelegt von Florian Wagner aus Burgstall (Mitwitz) Juli 2019 Das Promotionsgesuch wurde eingereicht am: 12.07.2019 Die Arbeit wurde angeleitet von: Prof. Dr. Christoph Oberprieler Unterschrift: ……………………………....... Florian Wagner iv Abstract Plant systematics, the study of taxonomy, phylogeny and evolutionary processes in plants has undergone considerable progress in the last decades. The application of modern molecular approaches and DNA-sequencing techniques in the field has led to an improved inventory of biodiversity and a better understanding of evolutionary processes shaping the biological diversity on our planet. The increased availability of molecular and genomic data has particularly facilitated the investigation of shallowly diverged and taxonomically complex taxon-groups, which is challenging due to minor morphological differences, low genetic differentiation and/or hybridization among taxa. The present thesis investigates species delimitation, hybridization and polyploidization in the recently diverged genera Leucanthemum Mill. and Rhodanthemum B.H. Wilcox & al. of the subtribe Leucantheminae K.Bremer & Humphries (Compositae, Anthemideae) by applying Sanger-, 454-pyro-, and restriction site associated
