C’est initialement grâce à Marie-Claude Huynen que j’ai pu entendre parler de ce projet de recherche passionnant en Afrique Centrale. Je souhaite te remercier pour ta présence, tes encouragements et la confiance que tu m’as accordée depuis mes premiers moments à Liège. C’est Alain Hambuckers qui m’a ensuite permis de prendre ce projet en main. Je me souviendrai longtemps de mon enthousiasme face à l’idée de mettre en place un projet sur la régénération forestière dans la brousse congolaise. J’ai rapidement dû m’adapter face à la multitude de possibilités qui m’étaient offertes et de challenges qui me barraient la route. Dès le début donc, ce projet a été énormément formateur et enrichissant. Alain, tu t’es montré incroyablement disponible pour écouter mes doutes, discuter, et me donner des conseils avisés pour avancer, étape par étape, tout en m’accordant beaucoup de confiance et de libertés quant aux choix que je faisais. Je t’en remercie grandement! Je remercie grandement la Politique Scientifique Fédérale Belge (Belspo) d’avoir financé ce projet pendant les deux premières années, le F.R.S.-FNRS pour m’avoir attribué une bourse FRIA les trois années suivantes, ainsi que le Patrimoine de l’ULg pour m’avoir appuyé financièrement pour que je puisse mener mes missions sur le terrain et participer aux congrès scientifiques. Je tiens à remercier les membres de mon comité de thèse, Marie-Claude Huynen, Roseline Beudels-Jamar, Louis François, et Pierre-Michel Forget, pour leur présence régulière et leur patience lors de mes présentations quelques peu redondantes, ainsi qu’à leurs nombreux conseils et encouragements. Pierre-Michel, avant notre rencontre, j’ai eu la chance de choisir une espèce de Myristicaceae pour mon projet, le lien était fait! Tu as rejoint le bateau en cours de route mais tu as été une personne clé pour ma thèse, et ton implication est loin de s’être limitée aux réunions annuelles du comité. Tu as toujours été partant pour prendre une journée pour venir à Liège et discuter de mes résultats plus ou moins satisfaisants malgré ton emploie du temps très chargé. Tes connaissances pointues ont sans aucun doute largement contribué à améliorer la qualité des différents chapitres. Tu m’as aussi poussé à donner une suite ambitieuse à la deuxième partie du projet. Merci! J’espère de tout cœur que cela portera ses fruits et que notre collaboration ne fait que commencer. Je voudrais remercier toutes les personnes qui m’ont accompagné pendant les différentes missions au Congo. Adeline Serckx, africaine blanche parfaitement organisée qui m’a appris dès mes premiers jours sur le continent à prévoir aussi bien des câpres et du parmesan pour agrémenter nos repas en brousse, que de gérer une équipe de pisteurs locaux pour récolter les données vitesse grand V. Jief, que dire? Passer de délires les plus absurdes, à des discussions sur la dynamique de succession forestière, et à l’organisation logistique pour aller camper dans «la savane aux éléphants» fût plutôt riche en émotions. Vous avez tous les deux été des personnes importantes pendant ma thèse, que ce soit pour les moments partagés sur le terrain que pour m’avoir inspiré et motivé dans mes recherches. Merci aussi à Ménard Mbende et Céline Devos pour leur accueil et leur aide précieuse à mes débuts à Malebo. Un tout grand Remerciements 7 merci à Jean Mobuli aka chef de base pour son aide et ses conseils toujours sages et précieux, ainsi que sa chaleureuse présence pendant les longs mois à Guantana-Malebo. Merci à toute l’équipe de la base de Malebo. Chab et Olivia, vous y êtes arrivés seulement à la fin de mon terrain, mais quel plaisir de vous avoir eu à mes côtés pour ma dernière mission! Je tiens aussi à remercier Paulin et Wivine de la ferme Mbou-Mon-Tour, ainsi que les chefs-de-terres des villages de Nkala, Embirima, Mpelu, et Mbanzi pour m’avoir autorisé à mener mes recherches dans leurs forêts. Toutes les données acquises résultent des efforts de nombreux pisteurs que je tiens à remercier chaleureusement : Mora, Pala, Ngamba, Americain, Nioka, Jean-Baptiste, Boula, Papa Denis, Idia, Mpesse. Merci également aux mémorantes Kim Mathy et Alice Dauvrin de m’avoir aidé pour la récolte de données. Je tiens aussi à remercier les équipes du WWF et de Mbou-Mon-Tour à Kinshasa pour leur support logistique. Enfin, merci à la moto Buxer de m’avoir permis des allez retours incessants entre mes nombreux sites d’études. Je voudrais remercier l’équipe des forestiers de Gembloux Agro-Bio Tech. Tout d’abord Cédric Vermeulen pour ton idée judicieuse de publier un article sur les camera-trap. Jean-Louis Doucet, pour ta disponibilité pour discuter de mes différents objectifs et méthodes. Tu as toujours fait des remarques constructives en mettant le doigt sur les points faibles de mon projet. C’est en fin de thèse que j’ai eu la grande chance de bénéficier de tes compétences de botaniste pour identifier mes centaines d’échantillons de plantes. Avec Jean-François Gillet et Olivier Lachenaud, vous avez été une ressource inestimable pour valoriser mes données. Je vous en remercie. Merci aussi aux différents membres de l’équipe de Foresterie Tropicale pour leur accueil lors de mes journées de transit à Gembloux. J’ai durant cette thèse rencontré plusieurs personnes d’une grande richesse qui m’ont toujours inspiré et accompagné, que ce soit en Belgique ou ailleurs sur la planète lors de conférences: Laurence, Fany, Barbara, Nima, Lauranne, Yaëlle. Je tiens aussi à remercier Thomas Drouet et David Bauman pour la collaboration de dernière minute et les analyses des échantillons de sols et les statistiques quelques peu précipités. Mais un tel projet n’est pas simplement le fruit de collaborations scientifiques, de kilomètres en forêt, et de longues heures passées devant Word et Excel. C’est aussi et sans nul doute grâce à un soutien extérieur que j’ai eu la chance de mener ce bout de chemin et de conduire à bien mon projet tout en restant équilibré. Je voudrais ainsi remercier tout particulièrement ma moitié pour son respect dans mes choix et son incroyable patience pendant mes périodes d’absences souvent trop longues et épicées à coup de Plasmodium falciparum, ainsi que mes périodes de confinement devant l’ordinateur parsemées de « j’ai pas le temps je dois bosser ». Jantje, tu m’a toujours accompagné et encouragé pour que je poursuive dans ma voie, et ce malgré les compromis à faire. Pendant ces cinq années, tu m’as aidé à relativiser et à garder les pieds sur terre pendant les périodes difficiles, les départs, les retours, les «après». Et, parlant sans cesse de graines qui germent et de jeune plantes qui poussent, je me devais moi-même de faire cette magnifique expérience biologique et de m’investir ailleurs que dans la quête interminable de résultats significatifs: notre petit Jules en est la plus belle des concrétisations. Merci milles fois pour tout. Je souhaite finalement remercier profondément ma famille pour leurs encouragements et leur soutien tout au long de ce projet. 8 Résumé Résumé Les patrons de biodiversité dans les forêts tropicales humides résultent d’interactions complexes à l’échelle de la communauté, tels que la dispersion des graines par les animaux. Les activités anthropiques (chasse, perte et fragmentation des forêts, etc.) perturbent ces processus écologiques et menacent ainsi le maintien de la diversité à l’échelle de la communauté végétale. Néanmoins, le niveau de résilience des processus impliqués dans la régénération forestière dans les paysages perturbés demeure incertain. La présente thèse vise à comprendre comment les services de dispersion des graines assurés par les grands frugivores ainsi que leur rôle fonctionnel dans la régénération des plantes sont affectés dans un paysage influencé par les activités anthropiques. Nous avons mené un travail de terrain dans une mosaïque de forêts- savanes en République Démocratique du Congo, un paysage ayant une structure spatiale fragmentée et qui abrite des activiés anthropiques (chasse, agriculture itinérante sur brûlis). Premièrement, nous avons examiné les services de dispersion des graines assurés par un grand primate menacé, le bonobo (Pan paniscus). Les bonobos dispersent une majorité de grandes graines que peu d’autres frugivores peuvent disperser, qui incluent de nombreuses espèces sciaphiles.

  • Impacts of Global Climate Change on the Phenology of African Tropical Ecosystems
    IMPACTS OF GLOBAL CLIMATE CHANGE ON THE PHENOLOGY OF AFRICAN TROPICAL ECOSYSTEMS GABRIELA S. ADAMESCU MSc by Research UNIVERSITY OF YORK Biology October 2016 1 Abstract The climate has been changing at an unprecedented rate, affecting natural systems around the globe. Its impact has been mostly reflected through changes in species’ phenology, which has received extensive attention in the current global-change research, mainly in temperate regions. However, little is known about phenology in African tropical forests. Africa is known to be vulnerable to climate change and filling the gaps is an urgent matter. In this study we assess plant phenology at the individual, site and continental level. We first compare flowering and fruiting events of species shared between multiple sites, accounting for three quantitative indicators, such as frequency, fidelity for conserving a certain frequency and seasonal phase. We complement this analysis by assessing interannual trends of flowering and fruiting frequency and fidelity to their dominant frequency at 11 sites. We complete the bigger picture by analysing flowering and fruiting frequency of African tropical trees at the site and community level. Next, we correlate three climatic indices (ENSO, IOD and NAO) with flowering and fruiting events at the canopy level, at 16 sites. Our results suggest that 30 % of the studied species show plasticity or adaptability to different environments and will most likely be resilient to moderate future climate change. At both site and continental level, we found that annual flowering cycles are dominant, indicating strong seasonality in the case of more than 50% of African tropical species under investigation.

  • 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 main rain forest area in Africa is the Guineo-Congolian region that extends from Senegal to western Kenya and northern Angola (White 1979; Figure 1a). Although the rain forests in this region are generally less diverse than those in the Neo- tropics and Indo-Malaysia (Huston 1994), they are estimated to house more than half of Africa’s species (Sayer et al. 1992). For example, the region holds some 84% of the primate species, 68% of the passerine bird species and 66% of the butterfly species found in Africa (Crowe & Crowe 1982; Carcasson 1964; Sayer et al. 1992). In addition, an esti- mated 8000 plant species are found in the Guineo-Congolian region (Sayer et al. 1992) Figure 1.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract A study was carried out in the 50-ha Korup Forest Dynamic Plot in South West Cameroon, to eva- luate the diversity of mycorrhizal associations as well as to determine the effect of habitat types on the type of mycorrhizal association. A total of 781 individual trees belonging to 51 families, 165 genera and 252 tree species, were sampled from the four habitat types found in the plot: low drier, hill slope, ridge top and wetland complexes. In each habitat type, all stems ≤ 1 cm depth at breast height had already been tagged, measured, mapped and identified to the species level. Root sam- ples were collected, cleared, stained and examined microscopically for mycorrhizal type. Of the total number of species sampled, 248 (98.41%) formed mycorrhizal associations with only 4 (1.59%) being non mycorrhizal. For mycorrhizal trees, 232 (93.55%) formed exclusively arbus- cular mycorrhiza, 10 (4.03%) formed ectomycorrhiza, while 6 (2.42%) formed both ecto- and ar- buscular mycorrhiza.

DOI: DOI: http://dx.doi.org/10.22034/srls.2020.520831.1008 Abstract The abundance and diversity of bird species were studied in Ehor Forest Reserve Edo state, Nigeria. The study area was divided into three compartments based on their different land-use types. The line transects method was used to collect bird species diversity and abundance in the study area. In all of 60 transect lines were randomly placed, measuring 1000 m. Each transect was divided into 200 m sections, with each block having 20 transects randomly placed. The site size determined the number of transect lines. Data were collected for six months (Dry and Wet seasons) in 20018. The quadrant method was used to determine plant species composition. This method involves a total enumeration count (TEC) of all trees above 1m in height and a Basal area of not less than 10cm from 25×25m2 quadrant sample plot, which was randomly selected through balloting from each sampling compartments.
