Beudels-Jamar Co-supervisor Institut Royal des Sciences Naturelles de Belgique Marie-Claude Huyen Co-supervisor Université de Liège Pascal Poncin Supervisor Université de Liège i “A long time ago, Bonobo and the humans were living together in the villages. One day, the tax inspector visited the village and Bonobo had no money. For lack of two francs, Bonobo run away in the forest with his wife. Too shameful of its behaviour and while hairs were growing on his body, Bonobo did not dare to come back in the village and became the Human of the forest.” “A long time ago, the oil palm and the raphia palm were fighting to know which one was the most powerful. The oil palm said “my fruits provide oil”, the raphia palm retorted “with my branches, clothes are weaved”. While they could not find a common ground, they asked Bonobo to stop the quarrel. Bonobo agreed that oil palm was right. The raphia palm was angry and responded “since you gave right to the oil palm, I take back my branches with which your clothes are weaved”. He took back the clothes and Bonobo was naked. Shameful, Bonobo ran away in the forest and never came back in the village.” Teke tales ii ACKNOWLEDGEMENTS / REMERCIEMENTS When I started my PhD thesis, I never imagined how much this project would become a wonderful adventure. I learnt so much about sciences, I met so many interesting people. I also had the opportunity to experience the life in Congo. I never expected I should have to fight against ants to protect my house, to spend 36 hours on a plastic seat in a boat to reach the field or to attach my phone on a stake to be able to make phone calls! But it was so wonderful to be immersed in the Teke culture, I only keep good memories of all these months spent in the field. I must confess that I do not consider this thesis as my work but rather as a wonderful project that I had the chance to conduct. So many people help me by giving time, energy, advices and I really would like to thank you all for your contributions in my thesis! Let’s go back a few years ago to remember thanks to whom this project has been possible. November 2008 Roseline, I remember when I entered for the first time in your office. I did not have any idea of what I could do in my life but I was sure that I wanted to work in conservation biology. You asked me “if you had the choice, what would you really like to do?”. I was dreaming about bonobos and this wonderful adventure started. Thanks you so much for having opened the doors of my deepest dreams, thanks you for all your advices, for sharing your experience, for all the time you spent to correct my work even when you were travelling across the world. You really support me since the beginning and nothing would have been possible without you! December 2008 One month later, I arrived at the University of Liege with an outline of this PhD project. I really thank Pascal Poncin for welcoming me in his team, for having supported my project and for giving me the opportunity to work in the Primatology Research Group. The second person who gave me the opportunity to accomplish this project is without any doubt Marie-Claude. You gave me judicious advices, constant support, so many times for reading, correcting and commenting my writings. You always find the solution to overcome each obstacle in this PhD and I cannot thank you enough for what you have done. September 2009 My thesis really started after months of preparation and thanks to the funding of the FRIA (Fonds pour la Formation a la Recherche dans l’Industrie et l’Agriculture) and of the F.R.S- F.N.R.S (Fonds National pour la Recherche Scientifique). Other funding also helped me later, that I should already thank: the University of Liege, the Leopold III foundation and the ERAIFT (Ecole Régionale post-universitaire d’Aménagement et de gestion Intégrés des Forêts et Territoires tropicaux). iii Since this period, I am also benefiting from the help and the advices of Alain Hambuckers and Regine Vercauteren. Thanks you so much for having participated to the development of this work! I also would like to thank Jan Bogaert and Jean-Louis Doucet, who were always present to answer my questions. I warmly thank all my colleagues from the University and the Museum for those funny lunch time and for the nice atmosphere in our offices. A special thanks to Barbara, Fany and Chab for the great times at the congresses. March 2010 When I arrived for the first time in the field, I met Pupa (Valentin Mbenzo). You gave yourself the mission to make me meet everybody in the villages, to teach me everything about the place, the local culture, the bonobos and your work. I am really convinced this is thanks to you that all my work on the field was possible, even when you were not there anymore. Thanks you for continuing to take care of me and I really hope that we could have new opportunities to work together. I am grateful to Menard Mbende for all his help and his advices in the field, for his wonderful capability to resolve each problem, for all his stories about Congo and for his humour in each situation. Je dois aussi remercier Daniel Malalu, qui m’a conduit un peu partout sur le terrain, à répétitions de « sois calme » à chaque pente où j’avais peur que les freins de la voiture lâchent et en me mettant en tête ce refrain qui ne m’a toujours pas quitté (« Mon père avait raison, ma mère avait raison,… »). I also thank Jean Mobuli and Petra Lahaan, even if they arrived later in the field. Jean, tu as vraiment transformé cette base WWF en un endroit agréable à vivre et tu fais un travail formidable. Don’t give up ! Nous revenons bientôt avec un disque dur pleins de films pour occuper tes longues soirées d’hiver. Petra, thanks you so much for our collaboration, I really hope we will have new opportunities to meet each other. Je remercie également toutes les autres personnes du WWF-Congo pour leur aide dans la préparation de chaque mission de terrain, et tout particulièrement Raymond Luebuenamo qui m’a ouvert les portes de Malebo. And besides all the support of WWF-Congo, I warmly thank people from WWF-Belgique, who helped me numerous time! Je remercie également Mbou-Mon-Tour de m’avoir accueilli dans leur ferme, Paulin pour ton aide quotidienne, Jean-Christophe pour le travail formidable que vous accomplissez. Je dois aussi dire un tout grand merci aux chefs de terre de Nkala et Mpelu, merci de m’avoir accueilli dans vos villages, de m’avoir permis de travailler dans vos forêts, de m’avoir fait partager avec vous et avec les autres villageois de si bons moments, de si bonnes fêtes du 30 juin. Nazali kobosana bino te, nakozonga mpembeni ! iv September 2010 Mais l’ensemble de ce travail n’aurait vraiment pas été possible sans l’aide de tous mes assistants de terrain, Yaya Cicé, Petit Mowa, Mpesse, Mafa, Bula, Pala, Papa Fido, et tous ceux qui nous ont aidé à couper les transects chaque année. Cicéron, tu as vraiment accompli un travail formidable et je t’en suis énormément reconnaissante. Sans toi, cette thèse n’aurait pas été possible. Tu as su gérer nos équipes en mon absence, apprendre à chacun le travail avec une patience et un savoir-faire impressionnant. Travailler avec toi était une expérience magnifique, tu t’es investi, tu t’es intéressé à ce que nous faisions et tu m’as appris tellement de choses. J’espère que tu garderas cette curiosité et cette soif d’apprendre et qu’elles te permettront d’accomplir cette nouvelle aventure qu’est l’université. Je te souhaite énormément de courage, je suis toujours là si tu as besoin de moi et j’attends avec impatience de retravailler avec toi. Mowa, j’ai passé des moments formidables avec toi en forêt, merci pour ton dévouement dans notre travail. Je te souhaite pleins de succès à l’école et j’espère que nous pourrons retravailler ensemble bientôt. Je remercie également les pisteurs bonobos, qui m’ont aidé à localiser les sites de nids, à collecter les fèces, et qui ont partagé avec moi leurs connaissances des bonobos de la région.

Accepted 4 October, 2010 The Upper Nyong valley belongs to the forest ecological area of Cameroon. Local people living around use drastically natural resources to enhance their livelihoods. According to the Cameroon forest law, more than 30% of natural area must be transformed into park and reserves. In the process of transformation, ecological studies can be conducted to evaluate potential resources available. This paper highlighted some results of a floristic survey conducted in the Upper Nyong valley through the Cameroon wildlife conservation project (CWCS), in order to evaluate the ecological and ethnobotanical uses of forest products and derived resources. The methodology used was based on linear transects and quadrats. As a result, 352 useful plants were inventoried and categorized into medicinal, food, traditional furniture, threatened and industrial plants. As implications and relevance to management, this study would help in the implementation of protected forest network coupled with the decentralization of forest resources. This could be the most sustained alternative for the conservation of this heritance from generation to generation.

INTRODUCTION AND ACKNOWLEDGEMENTS All the species dealt with in this study were collected in the Ivory Coast, Africa by VERSTEEGH and DEN OUTER in 1969. Although most collecting areas are near the main roads, a sufficient allround impression of the forest situation could be obtained because smaller or larger forested areas are often within reach of the road. Only those trees, shrubs and climbers which were flowering or fruiting in secondary forest-areas, mangrove and the savanna were examined. A few were collected in old plantations. One of the reasons to make the collection was to prepare a determination key kept as simple as possible, based on field characters and particularly those of the bark. The total number of considered species is 593, viz.: 144 trees with a dbh of more than 25 cm, 180 trees with a dbh of less than 25 cm, 152 shrubs and 117 climbers.

  • Melliferous Plants for Cameroon Highlands and Adamaoua Plateau Honey
    Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey April 2011 i Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey A melliferous flower is a plant which produces substances that can be collected by insects and turned into honey. Many plants are melliferous, but only certain plants have pollen and nectar that can be harvested by honey bees (Apis mellifera adansonii in Cameroon). This is because of the bee’s physiognomy (their body size and shape, length of proboscis, etc.) A plant is classified as melliferous if it can be harvested by domesticated honey bees. This is a symbiotic relationship (both organisms benefit), with bees collecting nectar, and pollen for food, and useful plant substances to make propolis to fill gaps in the hive. Plants benefit from the transfer of pollen, which assures fertilization. The tables of 1. Native & Forest Plants, April 2011 i Melliferous plants for Cameroon Highlands and Adamaoua Plateau honey 2. Exotic, Agroforestry & Crop Trees and 3. Bee hating trees list many of the known melliferous plants in the Cameroon Highlands and Adamaoua Plateau. This is the mountain range stretching from Mt Oku in the Northwest, through the Lebialem Highlands and Dschang , to Mt Kupe and Muanengouba and to Mt Cameroon in the Southwest. The information presented covers the flowering period, the resources harvested by bees (Nectar, pollen, propolis, and honeydew). It is worth noting that each plant does not produce the same quantity or quality of these resources, and even among species production varies due to location, altitude, plant health and climate. Digital copies of presentations with photos of some of the plants can be obtained from CIFOR [email protected] , SNV, WHINCONET ([email protected]), ANCO ([email protected]) or ERUDEF [email protected] or [email protected] This data was collected from 2007 to 2010 based on interviews with beekeepers in the Northwest and Southwest, observations, information obtained from botanists in Cameroon and internationally, observations and a review of literature.

Accepted 17 December, 2013 Only one study has reported on the medicinal properties of Cordia platythyrsa (C. platythyrsa) though it is used in African traditional medicine for treatment of fever and pain. The current study aimed at investigating the analgesic and anti-inflammatory properties of C. platythyrsa using various animal models: writhing test, tail flick, thermal hyperalgesia, mechanically induced-pain, formalin-induced pain and carrageenan-induced inflammation tests. Like aspirin, the two doses of plant extracts used inhibited acetic acid-induced pain though these effects were weaker than the effects of morphine. Although, the plant extract significantly (p<0.01) inhibited thermal pain, its effects were less significant compared to morphine. Celecoxib (10 mg/kg) and plant extract (100 mg/kg) significantly inhibited thermal hyperalgesia compared to indomethacin. On the other hand, both doses of plant extract significantly increased mechanical pain thresholds 30 and 90 min post treatment.

Received 14 September, 2019; Accepted 22 October, 2019 In tropics, species diversity in agricultural systems is often assessed without distinction between native and exotic species. However, the conservation value of an ecosystem depends on its richness in native species. This study was conducted to determine the conservation value of agricultural systems in Togo megahotspot, one of the species-rich sites in Upper Guinean. Specifically, the study compares fallow systems (FS), coffee systems (COFS), cocoa systems (COCS) to forest relics (FR) on the one hand, and on the other hand the agricultural systems (FS, COFS, COCS) between them base on natives tree species diversity and composition. Sites have been selected to represent different forest lands use types. Plots (n = 233) of different sizes (400, 500 and 625 m²) were used for data collection. In each plot, all living trees (DBH ≥ 10 cm) were counted. Rarefaction, generalized linear models (GLM) and ecological distance approach were used to standardized and compare the data.

  • Quested FAO to Prepare a Long-Term Strategy for the FRA Programme Consistent with Prospects for Sustainable Funding
    -FRA 2015 WORKING PAPER- Guide for country reporting for FRA 2015 The Forest Resources Assessment Programme To promote a Global Forest Resources Assessment that meets long-term global needs, COFO in its twentieth session (2010), requested FAO to prepare a long-term strategy for the FRA programme consistent with prospects for sustainable funding. COFO in its twenty-first session (2012) endorsed this strategy and the implementation of FRA 2015 as a first step. This Guide is intended to support data collection and reporting as part of the FRA 2015 process. Exactly how FRA can contribute to increasing the area and quality of sustainably managed forest has not always been clearly stated, yet it is essential if the assessment is to target those users who contribute meeting the challenges of forest management in the 21st century. FRA can help shape both policy making processes, inform and encourage forest-related investment decisions by a wide range of actors, including governments, private companies, NGOs and donor organizations. FRA must also be able to adapt to meet different needs of the diverse global forest data users: governments, non- governmental organizations, the media, intergovernmental agencies, academia, research institutions and the private sector. Understanding and meeting these diverse client needs is an important on-going challenge and an important element in how FRA 2015 was designed. The new Forest Resources Information Management System (FRIMS), the Collaborative Forest Resources Questionnaire (CFRQ) and many of the changes in the reporting template for 2015 have been initiated to help achieve the following objectives: 1. Reducing the reporting burden and increasing harmonization of forest definitions 2.
