It is believed to have originated on Cupressus sempervirens from eastern Greece to just south of the Caspian Sea (Watson et al., 1999). This pest has been recognized as a separate species for only a short time (Watson et al., 1999) and much of the information on its biology and ecology has been reported under the name Cinara cupressi.

  • Contributions to the Life-History of Tetraclinis Articu- Lata, Masters, with Some Notes on the Phylogeny of the Cupressoideae and Callitroideae
    Contributions to the Life-history of Tetraclinis articu- lata, Masters, with some Notes on the Phylogeny of the Cupressoideae and Callitroideae. BY W. T. SAXTON, M.A., F.L.S., Professor of Botany at the Ahmedabad Institute of Science, India. With Plates XLIV-XLVI and nine Figures in the Text. INTRODUCTION. HE Gum Sandarach tree of Morocco and Algeria has been well known T to botanists from very early times. Some account of it is given by Hooker and Ball (20), who speak of the beauty and durability of the wood, and state that they consider the tree to be probably correctly identified with the Bvlov of the Odyssey (v. 60),1 and with the Ovlov and Ovia of Theo- phrastus (' Hist. PI.' v. 3, 7)/ as well as, undoubtedly, with the Citrus wood of the Romans. The largest trees met with by them, growing in an un- cultivated state, were about 30 feet high. The resin, known as sandarach, is stated to be collected by the Moors and exported to Europe, where it is used as a varnish. They quote Shaw (49 a and b) as having described and figured the tree under the name of Thuja articulata, in his ' Travels in Barbary'; this statement, however, is not accurate. In both editions of the work cited the plant is figured and described as ' Cupressus fructu quadri- valvi, foliis Equiseti instar articulatis '. Some interesting particulars of the use of the timber are given by Hansen (19), who also implies that the embryo has from three to six cotyledons. Both Hooker and Ball, and Hansen, followed by almost all others who have studied the plant, speak of it as Callitris qtiadrivalvis.

Başer b a Department of Pharmaceutical Sciences, Faculty of Science, Tshwane University of Technology, Private Bag X680, Pretoria 0001, South Africa b Department of Pharmacognosy, Faculty of Pharmacy, Anadolu University, 26470-Eskişehir, Turkey Received 15 February 2010; received in revised form 31 March 2010; accepted 1 April 2010 Abstract Widdringtonia is the only genus of the 16 genera of Cupressaceae present in South Africa. This genus is represented by three species in South Africa; W. nodiflora, W. schwarzii and W. cedarbergensis (= W. juniperoides) and the latter listed as critically endangered. Cedarwood oil (generally obtained from Juniperus species) is widely used as a fragrance material in several consumer products, however, no data has been published on the volatiles of the Clanwilliam cedar (W. cedarbergensis) native to South Africa. The essential oil composition of the wood and leaf oil isolated by hydro-distillation were analysed by GC–MS. The two oils were distinctly different. Twenty compounds representing 93.8% of the total oil were identified in the leaf oil which was dominated by terpinen-4-ol (36.0%), sabinene (19.2%), γ-terpinene (10.4%), α-terpinene (5.5%) and myrcene (5.5%). Twenty six compounds representing 89.5% of the total were identified in the wood oil with the predominance of thujopsene (47.1%), α-cedrol (10.7%), widdrol (8.5%) and cuparene (4.0%).

J., Martínez J. F., Buhagiar J. (2013). Genetic structure of Tetraclinis articulata, an endangered conifer of the western Mediter- ranean basin. Silva Fennica vol. 45 no. 5 article id 1073. 14 p. Highlights • The employment of ISSR molecular markers has shown moderate genetic diversity and high genetic differentiation in Tetraclinis articulata. • Genetic structure of populations seems to be influenced by the anthropogenic use of this species since historical times, or alternatively, by the complex palaeogeographic history of the Mediterranean basin. • Results could be used to propose management policies for conservation of populations. Abstract Tetraclinis articulata (Vahl) Masters is a tree distributed throughout the western Mediterranean basin. It is included in the IUCN (International Union for Conservation of Nature) red list, and protected by law in several of the countries where it grows. In this study we examined the genetic diversity and genetic structure of 14 populations of T. articulata in its whole geographic range using ISSR (inter simple sequence repeat) markers. T. articulata showed moderate genetic diversity at intrapopulation level and high genetic differentiation. The distribution of genetic diversity among populations did not exhibit a linear pattern related to geographic distances, since all analyses (principal coordinate analysis, Unweighted pair group method with arithmetic mean dendrogram and Bayesian structure analysis) revealed that spanish population grouped with Malta and Tunisia populations.

  • Cheŵa Women's Instructions in South-Central Africa
    [Downloaded free from http://www.conservationandsociety.org on Monday, January 16, 2017, IP: 187.227.107.114] Conservation and Society 14(4): 406-415, 2016 Article Animals’ Role in Proper Behaviour: Cheŵa Women’s Instructions in South-Central Africa Leslie F. Zubieta Current affiliation: Centre for Rock Art Research + Management, The University of Western Australia, Perth, Western Australia, Australia E-mail: [email protected] Abstract The most common role of animals in the Cheŵa culture of south-central Africa is twofold: they are regarded as an important source of food, and they also provide raw materials for the creation of traditional medicines. Animals, however, also have a nuanced symbolic role that impacts the way people behave with each other by embodying cultural protocols of proper — and not so proper — behaviour. They appear repeatedly in storytelling and proverbs to reference qualities that people need to avoid or pursue and learn from the moral of the story in which animals interplay with each other, just as humans do. For example, someone who wants to prevent the consequences of greed is often advised to heed hyena stories and proverbs. My contribution elaborates on Brian Morris’s instrumental work in south-central Africa, which has permitted us to elucidate the symbolism of certain animals and the perception of landscape for Indigenous populations in this region. I discuss some of the ways in which animals have been employed to teach and learn proper behaviour in a particular sacred ceremony of the Cheŵa people which takes place in celebration of womanhood: Chinamwali. Keywords: Animal symbolism, initiation, Cheŵa, rock art, behaviour, Indigenous women, south-central Africa, Indigenous knowledge, Chinamwali INTRODUCTION highway.

Proposal To list the species Widdringtonia whytei in CITES Appendix II without annotation specifying the types of specimens to be included, in order to include all readily recognizable parts and derivatives in accordance with Resolution Conf. 11.21 (Rev. CoP17). On the basis of available trade data and information it is known that the regulation of trade in the species is absolutely necessary to avoid this critically endangered species, with major replantation efforts underway, becoming eligible for inclusion in Appendix I in the very near future.

Overview Widdringtonia whytei or Mulanje cedar, the national tree of Malawi, is a conifer in the cypress family endemic to the upper altitude reaches of the Mount Mulanje massif (1500-2200 a.s.l.). This highly valued, decay- and termite-resistant species is considered to be “critically endangered” by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species after years of overexploitation from unsustainable and illegal logging combined with human-induced changes to the fire regime, invasive competing tree species, aphid infestation, and low rates of 1 This document has been submitted by Malawi.

A study was conducted for the first time under controlled conditions in order to assess the effects of temperature and light on germination and viability of W. whytei seeds. Seeds incubated at a constant temperature of 20 °C attained the highest cumulative germination percentage (100%) followed by 87% germination under fluctuating temperatures of 15 °C night/25 °C day. No seed germination occurred at temperatures below 15 °C. Seeds that failed to germinate at temperatures below 15 °C showed the highest (N90%) viability compared to the seeds incubated at 25 °C (60%). Across temperature regimes, germination was significantly higher under light (44.7%) than dark (35.6%) conditions. It is concluded that temperature is one of the critical factors for germination of W.
