The purpose of this portion of the PASA obligation is to present previously published information on the tree and wood characteristics of selected secondary species growing m seven tropical countries. The format is concise and follows the outline developed for the second edition of the "Handbook of Hardwoods" published by HMSO, London. Species selected for review are well known in the source countries, but make up a very small component, if any, of their export trade. The reasons why these species play a secondary role in the timber harvest are discussed in the other accompanying PASA reports. ii INDEX Pages SURINAM 1-11 Audira spp. Eperu falcata Eschweilera spp. Micropholis guyanensis Nectandra spp. Ocotea spp. Parinari campestris Parinari excelsa Pouteria engleri Protium spp.

    Antonio-Nkondjio et al. Parasites & Vectors (2017) 10:472 DOI 10.1186/s13071-017-2417-9 REVIEW Open Access Review of the evolution of insecticide resistance in main malaria vectors in Cameroon from 1990 to 2017 Christophe Antonio-Nkondjio1,5*, N. Sonhafouo-Chiana2, C. S. Ngadjeu3, P. Doumbe-Belisse3, A. Talipouo3, L. Djamouko-Djonkam4, E. Kopya3, R. Bamou4, P. Awono-Ambene1 and Charles S. Wondji5 Abstract Background: Malaria remains a major public health threat in Cameroon and disease prevention is facing strong challenges due to the rapid expansion of insecticide resistance in vector populations. The present review presents an overview of published data on insecticide resistance in the main malaria vectors in Cameroon to assist in the elaboration of future and sustainable resistance management strategies. Methods: A systematic search on mosquito susceptibility to insecticides and insecticide resistance in malaria vectors in Cameroon was conducted using online bibliographic databases including PubMed, Google and Google Scholar. From each peer-reviewed paper, information on the year of the study, mosquito species, susceptibility levels, location, insecticides, data source and resistance mechanisms were extracted and inserted in a Microsoft Excel datasheet. The data collected were then analysed for assessing insecticide resistance evolution. Results: Thirty-three scientific publications were selected for the analysis. The rapid evolution of insecticide resistance across the country was reported from 2000 onward. Insecticide resistance was highly prevalent in both An. gambiae (s.l.) and An. funestus. DDT, permethrin, deltamethrin and bendiocarb appeared as the most affected compounds by resistance. From 2000 to 2017 a steady increase in the prevalence of kdr allele frequency was noted in almost all sites in An.

    CHARACTERISTICS OF TEN TROPICAL HARDWOODS FROM CERTIFIED FORESTS IN BOLIVIA PART I WEATHERING CHARACTERISTICS AND DIMENSIONAL CHANGE R. Sam Williams Supervisory Research Chemist Regis Miller Botanist and John Gangstad Technician USDA Forest Service Forest Products Laboratory1 Madison, WI 53705-2398 (Received July 2000) ABSTRACT Ten tropical hardwoods from Bolivia were evaluated for weathering performance (erosion rate, dimensional stability, warping, surface checking, and splitting). The wood species were Amburana crarensis (roble), Anudenanthera macrocarpa (curupau), Aspidosperma cylindrocarpon Cjichituriqui), Astronium urundeuva (cuchi), Caesalpinia cf. pluviosa (momoqui), Diplotropis purpurea (sucupira), Guihourriu chodatiuna (sirari), Phyllostylon rhamnoides (cuta), Schinopsis cf. quebracho-colorudo (soto), and Tabeb~liuspp. (lapacho group) (tajibo or ipe). Eucalyptus marginatu Cjarrah) from Australia and Tectonu grandis (teak), both naturally grown from Burma and plantation-grown from Central America, were included in the study for comparison. The dimensional change for the species from Bolivia, commensurate with a change in relative humidity (RH) from 30% to 90%, varied from about 1.6% and 2.0% (radial and tangential directions) for Arnburunu cer~ren.risto 2.2% and 4.1% (radial and tangential) for Anadenanthera macrocarpu. The dimensional change for teak was 1.3% and 2.5% (radial and tangential) for the same change in relative humidity. None of the Bolivian species was completely free of warp or surface checks; however, Anadenanthera macrocarpu, Aspidosperma cy- lindrocurpon, and Schinopsis cf. quebracho-colorado performed almost as well as teak. The erosion rate of several of the wood species was considerably slower than that of teak, and there was little correlation between wood density and erosion rate. Part 2 of this report will include information on the decay resistance (natural durability) of these species.

On a ainsi vu apparaître les concepts de forêt communautaire et des forêts communales. Les communes prenaient ainsi la possibité d’acquérir et de gérer une partie du domaine forestier permanent (art 20 de la loi de 1994) pour leur propre compte. La Commune dispose à cet effet de toutes les ressources fauniques et floristiques qui s’y trouvent à condition de respecter les prescriptions du plan d’aménagement approuvé par l’administration. Par décret N° 2002/1070/PM/ du 19 juin 2002 du 1 er Ministre, il a été classé une portion de 15 270 ha de forêt dans le domaine privé de la commune de Djoum. Conformément aux dispositions des textes en vigueur, cette forêt ne peut entrée en exploitation qu’après la validation de son plan d’aménagement. La Commune devait ainsi réaliser : - la cartographie de base de ce massif ; - un inventaire d’aménagement pour une meilleure connaissance du potentiel ligneux qui s’y trouve ; - une étude socio-économique pour évaluer le niveau de pression que connaît ce massif de la part des populations et leurs attentes par rapport à son exploitation ; - rédiger un plan d’aménagement ressortant les prescriptions de gestion de ce massif forestier.

  • African Mahogany Anegre Birdseye Maple Black Walnut
    African Mahogany African Mahogany (Khaya) is a genus of seven species of trees in the mahogany family Meliaceae, native to tropical Africa and Madagascar. All species become big trees 30-35 m tall, rarely 45 m, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet absent; each leaflet is 10-15 cm long abruptly rounded toward the apex but often with an acuminate tip. The leaves can be either deciduous or evergreen depending on the species. The flowers are produced in loose inflorescences, each flower small, with four or five yellowish petals and ten stamens. The timber of Khaya is called African mahogany, the only timber widely accepted as mahogany besides that of the true mahogany, of the genus Swietenia. Khaya senegalensis, also known as the African dry zone mahogany is also used for its non timber parts. In West Africa, Fulani herdsmen prune the tree during the dry season to feed cattle. Anegre Anegre is milled from the Tawa tree (Beilschmiedia tawa) is a New Zealand broadleaf tree common in the central parts of the country. Tawa is often the dominant canopy species in lowland forests in the North Island and north east of the South Island, Individual specimens may grow up to 30 meters or more in height with trunks up to 1.2 meters in diameter, and they have smooth dark bark. The word "tawa" is the Maori name for the tree. One of the few hardwood trees in the country with good timber, the wood of this tree can be used for attractive and resilient floor boarding.

  • Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607)
    Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607) by Nancy Ross Preface Since it was published in 1984, Tropical Timbers of the World has proven to be an extremely valuable reference to the properties and uses of tropical woods. It has been particularly valuable for the selection of species for specific products and as a reference for properties information that is important to effective pro- cessing and utilization of several hundred of the most commercially important tropical wood timbers. If a user of the book has only a common or trade name for a species and wishes to know its properties, the user must use the index of common names beginning on page 451. However, most tropical timbers have numerous common or trade names, depending upon the major region or local area of growth; furthermore, different species may be know by the same common name. Herein lies a minor weakness in Tropical Timbers of the World. The index generally contains only the one or two most frequently used common or trade names. If the common name known to the user is not one of those listed in the index, finding the species in the text is impossible other than by searching the book page by page. This process is too laborious to be practical because some species have 20 or more common names. This supplement provides a complete index of common or trade names. This index will prevent a user from erroneously concluding that the book does not contain a specific species because the common name known to the user does not happen to be in the existing index.

  • Choice of Suitable Regional and Residual Gravity Maps, the Case of the South-West Cameroon Zone
    Earth and Planetary Physics RESEARCH ARTICLE 3: 26–32, 2019 SOLID EARTH: GEODESY AND GRAVITY doi: 10.26464/epp2019004 Choice of suitable regional and residual gravity maps, the case of the South-West Cameroon zone Fidèle Koumetio1*, Donatien Njomo2, Constant Tatchum Noutchogwe3, Eric Ndoh Ndikum4, Sévérin Nguiya5, and Alain-Pierre Kamga Tokam2 1Department of Physics, Faculty of Science, University of Dschang, PO Box 67 Dschang, Cameroon; 2Department of Physics, Faculty of Science, University of Yaounde I, Cameroon; 3Department of Physics, ENS Bambili, University of Bamenda, Cameroon; 4Department of Fundamental Sciences, H.T.T.T.C. Bambili-Bamenda, University of Bamenda, Cameroon; 5Department of Physics, Faculty of Genial Engineering, University of Douala, Cameroon Abstract: The quantitative interpretation of gravity anomalies due to shallow structures needs separation between long wavelength anomalies (regional anomalies) and short wavelength anomalies (residual anomalies). The regional-residual field separation can be carried out using the polynomial method. In this case, the so-called regional field of order n is treated as a polynomial of degree n. The present study shows that the degree n must vary between a smallest value nmin and a maximum value nmax. This article presents a method to process gravity data that allows determination of nmin and nmax for a given study area. We apply the method to gravity data of the South-West Cameroon zone. In this chosen study area, we find that regional anomaly maps of orders ranging from 1 to 9 and residual anomaly maps of orders ranging from 1 to 8 can be used for suitable interpretation. The analyses show that one may need residual anomaly maps of several orders to perform satisfactory quantitative interpretation of the different intrusive bodies found in a given area.
