ZooKeys 547: 165–192. doi: 10.3897/zookeys.547.6018 Abstract The taxonomic circumscription of the large and diverse leaf beetle genusChrysolina Motschulsky is not clear, and its discrimination from the closely related genus Oreina Chevrolat has classically been controver- sial. In addition, the subgeneric arrangement of the species is unstable, and proposals segregating Chryso- lina species into new genera have been recently suggested. In this context, the availability of a phylogenetic framework would provide the basis for a stable taxonomic system, but the existing phylogenies are based on few taxa and have low resolution. -

Research Article
Journal of Fundamental and Applied Sciences Research Article ISSN 1112-9867 Available online at http://www.jfas.info EFFECTS OF TEMPERATURE AND SALINITY ON THE SEEDS GERMINATION OF Retama raetam (FORSSK.) WEBB. SCARIFIED WITH SULFURIC ACID Z. Mehdadi*, F. Z. Bendimered, M. Dadach and A. Aisset University of Djillali Liabes, Faculty of natural sciences and life, Laboratory of plant biodiversity: conservation and valorization, Sidi Bel Abbes, 22000, Algeria Received: 19 November 2016 / Accepted: 20 July 2017 / Published online: 01 Septemer 2017 ABSTRACT The present study consists of the elimination of tegumentary inhibition affecting seeds of Retama raetam by the chemical scarification. This pretreatment was carried out using pure sulfuric acid (98 %) and the seeds' germinative behavior was studied in the laboratory under controlled conditions of temperature and salinity. The results reveal that the chemical scarification by the sulfuric acid during six hours, had favored the germination of seeds which were incapable of germinating. The thermal optimum of germination expressed by the highest germination capacities and speeds as well as the shortest average times of germination and latency times corresponded to 20 °C and 25 °C. At low temperatures (0 °C and 5 °C) and high temperatures (35 °C and 40 °C), the germination was not possible.The seeds of R. raetam are sensitive to salinity, when the NaCl concentration increases the rate of germination decreases. The threshold of tolerance was recorded at 272 mM, from which the germination was inhibited. Key words: Retama raetam; chemical scarification; germination; temperature; salinity.

Their isolation has given rise to many endemic species and subspecies, of which the great views of Tenerife Blue Chaffinch in perfect light were a highlight for many. We marvelled over the flora, so different to that of mainland Europe, and enjoyed the various species of lizards, plus the butterflies and other invertebrates we encountered. The day on La Gomera was a delight, not least for the numbers of Cory’s Shearwaters, whales and dolphins, plus the White-faced Storm Petrels we encountered. Lovely weather with plenty of sunshine, comfortable accommodation, good food and great company all made for an excellent week. Day 1 Saturday 23rd February Fly to Tenerife South – La Chafiras – Road to Vilaflor Fifteen tour group members met with Andrew and Jessica at Gatwick’s North Terminal for the 6.50am Easyjet flight to Tenerife South Airport. After a bit of a delay due to fog at Gatwick, we landed on the island at around 12.15pm, meeting up with our last group member, who had arrived on the island the previous day. -

Received 23 August, 2017; Accepted 7 November, 2017. Calycotome spinosa (L.) Link is one of the important plants in traditional medicine especially in Algeria. The present work deals with the phytochemical screening, the flavonoids extraction from leaves and flowers of this plant, the quantification of total polyphenols and flavonoids, as well as the evaluation of antioxidant and antimicrobial properties of ethyl acetate and n-butanol fractions. While, the rest, interacted with its phenolics identification. The results of preliminary phytochemical screening showed that C. spinosa contained various metabolites: Polyphenols, flavonoids, alkaloids, saponins etc. In addition, the findings of polyphenols determination using Folin Ciocalteu was high in all the fractions: 107.75±0.41 and 64.24±1.81 mg gallic acid equivalents/g extract for leaves ethyl acetate and n-butanol respectively and 81.45±0.6 and 96.06±2.72 mg gallic acid equivalents/g extract for flowers ethyl acetate and n-butanol successively. -
Host Specificity of Uresiphita Reversalis (Guenee) (Crambidae)
.Journal o{ the LCl'id<Jl'terists' Society .51(2 ), 1997, 149- 1.5.5 HOST SPECIFICITY OF URESIPHITA REVERSALIS (GUENEE) (CRAMBIDAE) ROSEMARY LEEN United States D epartment of Agriculture, Forest Service, Pacific Southwest Research Station, P. O. Box 236, Volcano, Hawaii 96785, USA ABSTRACT. Host specificity tests were conducted on (Jresiphita reversalis and to a lesser degree on U. pulygonalis. First instal's of U. reversalis were limited to feeding on quinolizidine-bearing tribes of fabaceous legumes. However, U polygonali.Y from the Ca nary Islands and u. reversalis both fail ed to complete development on Cytisus scoparius (Genisteae) beyond the second instar. Cytisus scoparius and Cytisus striatus were never observed as hosts of U. reversatis in California during the years of this study (1984- 1989). Host range of U. reversa/is encompassed six quinolizidine-bearing tribes of the Fabaceae: Genisteae, Snphoreae, Thermopsidae, Bossiaeeae, Podalyreae, and Euchresteae, although the latter two tribes have not been reported as hosts in the field. Both native and intro duced species in quinolizidine-bearing tribes will undoubtedly be used by U. reversalis when the opportunity arises. Additional key words: Pyralidae, Pyraustinae, aposernatism, host plant range, French broom, quinolizidine alkaloids. Uresiphita reversalis (Guenee) expande d its host range from native legumes to include several introduced ornamental broom species. Feed ing by U. reversalis on Genista monspessulana (L.) L. Johnson (commonly known as French broom or Genista) was first reported to the USDA Agri cultural Research Service, Albany, California, in 1983 when larvae caused substantial defoliation of some populations in the San Francisco Bay area. -

Evaluation of Fatty Acids Profile and Mineral Content of Retama Monosperma (L.) Boiss
J. Mater. Environ. Sci. 6 (2) (2015) 538-545 El Hamdani & Fdil ISSN : 2028-2508 CODEN: JMESCN Evaluation of fatty acids profile and mineral content of Retama monosperma (L.) Boiss. of Morocco N. El Hamdani, R. Fdil* Laboratoire de Chimie bio organique, Faculté des Sciences, Université Chouaïb Doukkali, BP 299, 24000, El Jadida, Maroc Received 30 May 2014; Revised 20 September 2014; Accepted 21 September 2014. *Corresponding Author. E-mail: [email protected]; Tel: (+212 523342325 ) Abstract The content of lipids and the fatty acid (FA) profile were determined for branches/leaves (BLs) and seeds (Sds) of Retama monosperma. The total lipids were extracted with hexane and further derivatives to FA methyl esters (FAME). The analyses of FAME samples were performed by gas chromatography coupled to a flame ionisation detector. The total lipids content in BLs and Sds were 0.3 % and 5% respectively. The results indicate that palmitic acid (C16: 0) is the most abundant saturated FA in both Sds and BLs followed by stearic acid (C18: 0), while the oleic acid (C18:1n9) is the dominant mono-unsaturated FA in the Sds. The two samples contained linoleic (C18:2n6) and linolenic acid (C18:3n3) as major polyunsaturated acids. The greatest proportion of linoleic acid was found in Sds, while linolenic acid is highest in BLs. The traditional use of the Retama monosperma as an antidiabetic is probably related to its FA. The results of mineral analysis showed that all Sds and BLs contained considerable amount of macro and micro elements. Key words: Retama monosperma, Leguminosae, fatty acids, omega-3, omega-6, minerals 1. -
San Diego County Invasive Ornamental Plant Guide
SAN DIEGO COUNTY INVASIVE ORNAMENTAL PLANT GUIDE This Guide is produced and distributed by the San Diego Chapter of the American Society of the Landscape Architects (SD/ASLA) and the San Diego Chapter of the California Native Plant Society (CNPS) for the primary purpose of educating landscape professionals and the general-public regarding the cultivation, selection, use and management of non-native and/or invasive plants in San Diego regional landscapes. It is understood that this Guide is of special importance in the “urban interface”: areas where natural vegetation and man-made landscapes come into close contact. It is not the intent of the authors to add unnecessary constraints or to discourage the planting of a broad selection of native and non-native species where it is unlikely that their presence would have any effect upon indigenous plant populations or habitat. This Guide is provided solely as a reference document and is not intended for regulatory purposes. What is an Invasive Plant? An ‘Invasive Plant’ is a species that has become a weed pest: a plant that grows aggressively, spreads rampantly and displaces native plants. Invasive plants usually appear on disturbed ground and moist places, and the most aggressive can invade native areas. Invasive plants are generally undesirable because they can be difficult to control, can escape from cultivation, and can out-compete native plants. Invasive plant infestations can be environmentally destructive, costing government, resource agencies and private land owners millions of dollars each year to control and remove. Characteristics of Invasive Plants Invasive plants can be trees, shrubs, vines, groundcovers, grasses or aquatic plants. -
