Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -

LES ENJEUX ENTOURANT LA GESTION DÉCENTRALISÉE DES AIRES PROTÉGÉES EN CENTRAFRIQUE : LE CAS DE LA FORÊT DE BANGASSOU THÈSE PRÉSENTÉE À L’UNIVERSITÉ DU QUÉBEC À CHICOUTIMI EN VUE DE L’OBTENTION DU GRADE DE PHILOSOPHIAE DOCTOR (PH.D.) DANS LE CADRE DU PROGRAMME DE DOCTORAT EN DÉVELOPPEMENT RÉGIONAL OFFERT CONJOINTEMENT PAR L’UNIVERSITÉ DU QUÉBEC À CHICOUTIMI ET L’UNIVERSITÉ DU QUÉBEC À RIMOUSKI PAR © HILAIRE TCHÉCHOUPARD Août 2017 DEDICACE À nos chers enfants afin qu'ils suivent notre exemple en matière de persévérance dans les études ! II REMERCIEMENTS Cette thèse est le couronnement de plusieurs années de recherche, de stress, de solitude, d’inquiétude, de remise en question, mais aussi de joie et de découvertes. En d’autres mots, cette thèse est le résultat d'un travail qui nous a souvent valu un surcroît d'efforts, de persévérance, de résilience et d'abnégation. Toutefois, celle-ci n'aurait pu être réalisée sans la contribution des uns et des autres qui, de près ou de loin, nous ont soutenu financièrement, matériellement, moralement et scientifiquement. Ainsi, nous voudrions exprimer particulièrement nos sincères remerciements aux personnes-ressources et institutions ci-après. Tout d’abord, nous formulons notre profonde gratitude au comité de supervision de notre thèse. En premier lieu, nous disons un grand merci à notre codirecteur, M. Jules Dufour, professeur émérite à l’Université du Québec à Chicoutimi, qui, depuis la formulation du sujet jusqu'à la finalisation de cette thèse, n'a cessé de nous canaliser avec ses riches expériences et compétences scientifiques en développement durable et notamment dans le domaine des aires protégées. -

A Preliminary checklist of the Vascular Plants and a key to Ficus of Goualougo Triangle, Nouabalé-Ndoki National Park, Republic of Congo. Sydney Thony Ndolo Ebika MSc Thesis Biodiversity and Taxonomy of Plants University of Edinburgh Royal Botanic Garden Edinburgh Submitted: August 2010 Cover illustration: Aptandra zenkeri, Olacaceae Specimen: Ndolo Ebika, S.T. 28 By Sydney Thony Ndolo Ebika Acknowledgments Acknowledgments The achievement of this MSc thesis in Biodiversity and Taxonomy of Plants is the result of advice, support, help and frank collaboration between different people and organizations and institutions. Without these people this thesis could not have been achieved. My deep grateful thanks go to both Dr. Moutsamboté, J.-M. ( Rural Development Institute, Marien Ngouabi University, Republic of Congo ) and Dr. Harris, D.J. (Royal Botanic Garden Edinburgh) who gave me a powerful boost in studying plants during the botanic training workshop titled Inventory and Identification they organized at Kabo, Republic of Congo, in August 2006. Especially I would like to thank Dr. Harris, because the collaboration he established with the Goualougo Triangle Ape Project, Nouabalé- Ndoki National Park (NNNP), project I was working for, and his continued support for me has been very important to my training as a botanist. The Goualougo Triangle Ape Project (GTAP) is the area where all of the specimens treated in this thesis were collected. The team of this project was always looking after me night and day from 2006 to 2009. I would like to thank both principal investigators of the Triangle both Dr. Morgan, D. and Dr. Sanz, C. for their support to me. -
Compilation of Available Biological Information on Salonga National Park, Democratic Republic of Congo
COMPILATION OF AVAILABLE BIOLOGICAL INFORMATION ON SALONGA NATIONAL PARK, DEMOCRATIC REPUBLIC OF CONGO September 2007 Dr. Fiona Maisels Wildlife Conservation Society, DRC Biodiversity, Salonga. Complied by Fiona Maisels WCS Africa Programme With the generous help of : Callan Cohen, Ian Harrison, Bila-Isia Inogwabini, Gay Reinartz, Bob Schelly, Lisa Steel, and Melanie Stiassny. Objective: Complete the compilation and synthesis of all existing biological information on the park (spatially and descriptively). Taxa covered are: - Plants - Fish - Birds - Mammals Methods There is little existing documentation of the Salonga area. A few publications list taxa for small areas of this landscape, so individual people were contacted and unpublished information (lists or maps of occurrence of species) requested. The data received, and what is published, are presented in this report either as lists, or as maps culled from existing reports. Each list is accompanied by a map showing sites where the data was collected, and, for the large mammals, maps of distribution have been possible. No data on reptiles or amphibians were found specifically for Salonga. 1. Plants Four main sources were used here. Jean-Baptiste Dhetchuvi and Maisels et al worked in the northern sector of the Salonga National Park, at Botsima (Fig. 1). The Maisels et al list comprises mostly species eaten by primates, or larger trees. Dhetchuvi collected as a botanist, so all life forms are represented. Reinartz and Inogwabini worked mostly out of Etate, again in the northern sector (Fig. 1), to the west of the Park. The Reinartz et al list comprises species used for nests by bonobos, or eaten by bonobos, whereas the Inogwabini list is more general. -

The Ecology of Forest Elephant Distribution and Its Implications for Conservation
The Ecology of Forest Elephant Distribution and its Implications for Conservation Stephen Blake A thesis submitted for the degree of PhD University of Edinburgh 2002 PREFACE This thesis was written by myself and is the result of my own work, unless otherwise acknowledged at the end of appropriate chapters. ii ABSTRACT Genetic evidence suggests that extant African elephants, currently recognised as two sub-species in the genus Loxodonta, should be divided into distinct species; savannah elephants (L. africana) and forest elephants (L. cyclotis). Forest elephants are most abundant in the equatorial forest of the Congo Basin, and account for a considerable portion of Africa’s elephants. Despite their key role in forest ecosystems, few data on forest elephant ecology are available, at a time when intense hunting and widespread habitat fragmentation and conversion pose an increasingly severe extinction threat. A study of forest elephant ecology was initiated in the remote Ndoki Forest of northern Congo. The goal was to identify the ecological determinants of elephant distribution and ranging, and to determine the impact of human activity, at a relatively intact site. Data from a local, intensively surveyed site, and repeated extensive foot surveys over a 253km swathe of the Ndoki Forest, which traversed the northwest-southeast drainage gradient, revealed a spatial and temporal partitioning in the availability of resources important to elephants on several scales. Dicotyledon browse was most abundant in open canopy terra firma forest, light gaps, and swamps, while monocotyledon food was most concentrated in terra firma forest to the southeast, and was super-abundant in localised swamp patches. -
Pan Troglodytes Schweinfurthii) of Northern Democratic Republic of Congo
International Journal of Primatology https://doi.org/10.1007/s10764-020-00149-4 The Relationship Between Tool Use and Prey Availability in Chimpanzees (Pan troglodytes schweinfurthii) of Northern Democratic Republic of Congo Thurston C. Hicks1,2 & Hjalmar S. Kühl2,3 & Christophe Boesch2 & Steph B. J. Menken4 & John Hart5 & Peter Roessingh4 & Corneille Ewango6 & Roger Mundry7 Received: 5 August 2019 /Accepted: 24 February 2020/ # The Author(s) 2020 Abstract A key feature of human behavioral diversity is that it can be constrained by cultural preference (“cultural override”); that is, population-specific preferences can override resource availability. Here we investigate whether a similar phenomenon can be found in one of our closest relatives, as well as the potential impacts of ecological differences on feeding behavior. Our study subjects were different subpopulations of Eastern chimpanzees (Pan troglodytes schweinfurthii) occupying two very different habitats, moist tropical lowland forests vs. moist tropical forest–savanna mosaic on opposite sides of a major river. Given differences in encounter rates of different kinds of tool sites on both sides of the Uele River, we predicted that these subpopulations would differ in their likelihood of using tools to prey on two insect species despite similar availability. In surveys conducted over a 9-year period at 19 different survey regions in northern Democratic Republic of Congo (10 in lowland forest and 9 in mosaic), we collected and analyzed data on chimpanzee tool-assisted exploitation of insects. To determine the availability of insect species eaten by the chimpanzees, we counted insects and their mounds on transects and recces at 12 of these sites. -

Turumbu Indigenous Knowledge on Non-Cultivated Edible Plants
Eating from the Wild: Turumbu Indigenous Knowledge on Non-Cultivated Edible Plants, Tshopo District, DRCongo Céline Termote1, Patrick Van Damme1 and Dhed’a Djailo Benoît² 1Laboratory of Tropical and Subtropical Agronomy and Ethnobotany, University of Ghent, Coupure links 653, 9000 Gent, Belgium, Tel: +32 92646089, [email protected], [email protected] ²Laboratory of Genetics, Pplant Iimprovement and Bbiotechnology, Faculty of Science, University of Kisangani, BP 2012 Kisangani, DRCongo, Tel : +243 998609315, [email protected] ABSTRACT Documenting and revalorizing the rapidly disappearing indigenous knowledge on wild edible plants is essential to promote health and preserve diversity. Focus group discussions were organized within 3 Turumbu-villages to document wild foods known, availability, preparation methods and uses. Preferences in taste, commercial, nutritional and cultural value, were discussed during participatory ranking exercises. Results show 85 species within 70 genera and 454 families. Fruits of Anonidium manni and Landolphia owariensis, and (unfolded) leaves of Megaphrynium macrostachyum and Talinum triangulare are most appreciated. Inventories and preference rankings should be completed with nutritional analyses and market studies to set priorities for participatory domestication. KEYWORDS Domestication, Ethnobotany, Wild Edible Plants, Under-Utilized Crops 1 INTRODUCTION Biodiversity conservation is of utmost importance for agriculture and world food supply. However, existing biodiversity is still under-utilized to expand food production. About 30,000 of the more than 250,000 currently described plant species are edible, whereas about 7,000 have been cultivated or collected by humans for food at one time or another (FAO, 1997). Several thousands of species may thus be considered to contribute to food security, but the value of many species is under-estimated. -
