As a result, human presence has an important impact on the demography, behaviour, and overall ecology of the nonhuman primates’ populations. More specifically, the increasing human pressure represents a critical danger for the survival of most primate species, often leading to the local extinction of entire populations. However, some primate species show a high degree of plasticity when facing human disturbance, and even adapt their ecological behaviour to heavily modified urban areas. Our research project, in collaboration with the City of Bangkok, focuses on long-tailed macaques (Macaca fascicularis), a species distributed throughout all Southeast Asia, and showing a great ability to adapt to urban habitat. The goal of our study is to define the impact of urbanized habitat fragments on the social interaction and reproductive patterns of the macaque populations, in order to design sustainable management plans and reduce conflicts with local human populations. We present preliminary results from a 4 month study period (May to August 2007) on a large semi-provisioned troop living in the South of Bangkok suburban area. Data were collected via instantaneous scan sampling for activity budget, and focal sampling for diet, while aggressive and sexual interactions within the group were noted ad libitum. The study group, 128 animals (10 males, 6 subadults, 48 females of whom 39 with an infant, and 64 juveniles) appears to use an area highly disturbed by of human activities. In the coming year we plan to extend our observations to a second troop inhabiting an estimated area of 5 km2 of pristine mangrove with an ongoing forest regeneration project. <br/> <br/>Commentaires: Abstract published in Folia Primatologica (2008), 79(5): 315 http://hdl.handle.net/2268/150738 Titre: Ranging behaviour and sleeping sites of Macaca fascicularis in Bali Barat National Park, Indonesia <br/> <br/>Auteur, co-auteur: Brotcorne, Fany; Maslarov, Cindy; Dosogne, Thibaut; Wandia, I. Nengah; Beudels-Jamar, Roseline; Huynen, Marie-Claude <br/> <br/>Résumé: Ranging behaviour and sleeping site selection are important primate behavioural traits likely to vary under environmental changes. We tested the role of ecological (predation avoidance) and anthropic (human proximity) factors in Macaca fascicularis range use, an edge species known to prefer living along forests borders and in the vicinity of human settlements. Data result from 56 day follows of one group of Macaca fascicularis exploiting a human-modified landscape within Bali Barat National Park (Indonesia). Observations allowed identifying and describing 17 sleeping sites and the characteristics of 37 sleeping trees. Despite a large forest area available, the group’s home range centred around human settlements. The home range size, average daily range and daily travel decreased over the study period, while the human presence inside the park increased over the corresponding months. The proximity with humans also influenced the pattern of sleeping sites use; macaques slept more than expected close to human settlements and this tendency increased over the study period. In contradiction with the predation avoidance assumption, macaques did not choose sleeping trees significantly taller and larger than other trees available. We conclude that the observed sleeping site strategy (sleeping near humans) could be advantageous in terms of predator avoidance and proximity with human food, but additional influences should not be neglected. http://hdl.handle.net/2268/150723 Titre: BEHAVIOURAL ECOLOGY OF LONG-TAILED MACAQUES IN THE CONTEXT OF URBAN COMMENSALISM: A COMPARISON STUDY BETWEEN BANGKOK (THAILAND) AND BALI (INDONESIA) <br/> <br/>Auteur, co-auteur: Brotcorne, Fany; Huynen, Marie-Claude; Beudels-Jamar, Roseline; Savini, Tommaso; Wandia, I. Nengah; Fuentes, Agustin <br/> <br/>Résumé: The quest for coexistence with non-human primates requires an extensive analysis of the growing commen-salism phenomenon. The long-tailed macaque (Macaca fascicularis), a very successful commensal species, adapts remarkably to anthropogenic habitats. Studies in several Asian locations raised the issue of hu-man-macaque conflict related to human health and safety as well as to conservation threats on macaques. Here, we aimed at assessing the anthropogenic impact (human presence and provisioning frequency) on the eco-behavioural profile of two populations living commensally with humans in Bangkok (Thailand) and Ubud (Padangtegal, Bali). We used an identical focal and scan sampling methodology during two three-month study periods in 2007 (Bangkok) and 2009 (Bali). Despite different ecological conditions, the two populations showed a strongly similar activity budget. Resting was the most common activity (40% vs. 35%), followed by feeding (28% vs. 24%), moving (15% vs. 14%) and affiliations (14% vs. 19%). Agonistic behaviours were slightly more frequent in Bali (0.6% vs. 3.0%), maybe due to higher population density (8.5/ha vs. 14.2/ha). Contrary to previous studies, we did not find any impact of provisioning on agonistic interactions. Concerning diet composition, proportions of natural vs. provisioned food and proportions of various food categories were consistent between the two sites. Since the ecological conditions were different, the anthropogenic factors are likely to explain the strong consistency in eco-behavioural profile of the two populations. Further studies are planned on three other populations to assess the specific impact of commensalism on behavioural ecology and derive the implications for long term population trends. http://hdl.handle.net/2268/150716 Titre: Demographic changes and behavioural ecology of a commensal long-tailed macaque population at Padangtegal, Bali (Indonesia) <br/> <br/>Auteur, co-auteur: Brotcorne, Fany; Huynen, Marie-Claude; Wandia, I. Nengah; Fuentes, Agustin <br/> <br/>Résumé: The current anthropic pressures lead to a growth of the commensalism phenomenon with primates and humans interacting and competing for space and food. As these situations generate inter-specific conflicts, an extensive analysis seems essential for primate conservation issues. Bali (Indonesia) is characterized by a high density of long-tailed macaques (Macaca fascicularis) living in association with humans. The macaque population of the Padangtegal Monkey Forest (Ubud) has been the focus of successive studies since 1986 (Wheatley, 1986; Fuentes et al., 2007). Here, we present updated data (September-December 2009) on demography, activity budget and diet of this population while analyzing variations over time. The macaques at Padangtegal showed a substantial population growth over the last thirty years (34% average growth every 6 years). In 2009, we listed 498 individuals split in 5 groups with an average adult sex ratio of 1:4.5. The home range size also increased over time (7ha in 1986 vs. 30ha in 2009) but was finally limited by surrounded human infrastructures. Consequently, the population density doubled in the course of the last 8 years and counted 16.6 macaques per hectare in 2009. On the other hand, the activity budget pattern appeared quite stable over time with a large proportion of time spent inactive and socializing and a relatively small proportion of time spent in feeding activities. This activity pattern is characteristic of provisioned primate populations. Finally, the diet composition slightly varied over time except for the radical decrease of provisioned carbohydrate-rich food proportions, following some management decisions. Macaques at Padangtegal thus show some stability in their behavioural ecology despite considerable changes in demography. Nevertheless, these positive population trends do not protect macaques from some long term risks tied to commensalism, such as inbreeding depression and increased probability of disease transmission. http://hdl.handle.net/2268/150707 Titre: Food provisioning and agonistic behaviours in commensal long-tailed macaque (Macaca fascicularis) at Uluwatu Temple, Bali (Indonesia) <br/> <br/>Auteur, co-auteur: Brotcorne, Fany; Huynen, Marie-Claude; Wandia, I. Nengah <br/> <br/>Résumé: Most previous research on nonhuman primates reported increased levels of agonistic behaviors associated with food provisioning by humans. To further investigate the permanence of this effect of increased social competition in long-term commensal-living primates, we examined the immediate impact of food provisioning on agonistic behavior rates in a commensal population of long-tailed macaques (Macaca fascicularis) at Uluwatu Temple, Bali (Indonesia). We compared proportions of agonistic behaviors between various food provisioning levels defined by the absence/presence and the quantity of food provisioned. We collected data using focal and scan sampling methods during a four-month study period (June to October 2010). We performed non-parametric statistical tests (Wilcoxon Test & Friedman Test; p < .05) on a population sample of 66 individuals. Results did not show obvious impact of provisioning on agonism rates, nor increase of potential appeasement strategies such as sexual behaviours, grooming or self-directed behaviours, often associated with the presence of provisioned food. These data suggest that the long-tailed macaques at Uluwatu Temple are responding effectively to high provisioning level, that is, without increasing social competition. We hypothesize that the high spatiotemporal abundance of human food, associated with the species’ eco-behavioural flexibility and the long term story of human-macaque commensal relationships in Uluwatu may explain the absence of provisioning impact on agonistic rates. <br/> <br/>Commentaires: Abstract published in American Journal of Primatology (2011), 73(S1): 83 http://hdl.handle.net/2268/150645 Titre: Etude de la population d’hippopotames (Hippopotamus amphibius L.) de la rivière Mouena Mouele au Parc National du Loango-Sud (Gabon) <br/> <br/>Auteur, co-auteur: Michez, Adrien <br/> <br/>Résumé: Le Parc National du Loango ainsi que les 12 autres parcs nationaux gabonais créés en 2002 constituent une expérience sans précédent dans le domaine de la conservation en Afrique Centrale. La valorisation de ceux-ci, notamment scientifique, est une condition sine qua non à leur pérennisations dans le paysage gabonais. Le présent travail est le fruit de l’analyse d’une série de données récoltées sur l’hippopotame et son milieu au Parc National du Loango-Sud, plus particulièrement sur la population basée dans la rivière Mouena Mouele. Trois populations distinctes mais non-isolées ont été identifiées pour le sud du parc. Dans un rayon de 10 km autour d’un point fixé sur la rivière, une description des savanes a été réalisée, identifiant trois principaux types dominés respectivement par Axonopus compressus (Sw.) P.Beauv., Panicum congoense Franch. et Paspalum vaginatum Sw. Le régime alimentaire a été décrit via l’analyse d’échantillons de fèces comparés aux relevés phytosociologiques. Les principales espèces relevées dans les échantillons furent Paspalum vaginatum, Desmodium triflorum, Axonopus compressus et Stenotaphrum secundatum (Walt.) Kuntze. La fréquentation préférentielle par la population de certains types de savanes comme celle à Axonopus compressus a été également montré. Le statut de la population a été jugé en dessous d’un niveau de saturation, plusieurs facteurs limitant ont été identifiés telle une éventuelle pression anthropique combinée à une diminution de la ressource en saison sèche. Vu son rôle majeur dans l’écosystème, la conservation de l’hippopotame à Loango doit être considérée comme une priorité. http://hdl.handle.net/2268/150441 Titre: A bit of quiet between the migrations: the resting life of the European eel during their freshwater growth phase in a small stream <br/> <br/>Auteur, co-auteur: Ovidio, Michaël; Seredynski, Aurore; Philippart, Jean-Claude; Nzau Matondo, Billy <br/> <br/>Résumé: The movements and habitat use of resident yellow eels were studied in a stream stretch having both natural and minimum flow zones. N = 12 individuals (total length 505–802 mm) were surgically tagged with radio transmitters and released at their capture sites. They were located using manual radio receivers during the daytime from 2 to 5 days/ week over periods ranging from 200 to 329 days, for a total of 1,098 positions. Eels showed home ranges ranging from 33 to 341 m (median value, 62 m), displayed strong fidelity to sites and demonstrated a great degree of plasticity in habitat use. Eels were slightly mobile throughout the year, but their movements were season and temperature dependent, with a maximum during the spring (mean water temperature, 12 C) and a minimum in winter (3 C). Stones and roots (utilization rate greater than 50 % of eels for more than 30 % of location days) were significantly the most frequently used habitats. Between the two flow zones, the natural flow was the most occupied, with a significantly higher proportion of resident eels(66.7 % of radio-tagged yellow eels) and longer occupation (81 % of location days) than the minimum flow zone with less suitable habitats. http://hdl.handle.net/2268/149563 Titre: Expertise sous forme d'évaluation et d'encadrement dans les thématiques de la biodiversité végétale des prairies et de la biodiversité animale dans le cadre des méthodes agro-environnementales (MAE prairies et animaux) : ANNEXE 2 Evaluation environnementale de la méthode 1c Suivi biologique des mares <br/> <br/>Auteur, co-auteur: Dopagne, Claude <br/> <br/>Résumé: Le suivi des mares de la méthode 1c des mesures agro-environnementales a été initié en 2004 par une première évaluation sur 47 mares.

Par la suite, en 2007, 28 autres bandes fleuries (semis au printemps 2006) réparties sur les régions agricoles Famenne et Condroz ont été visitées2. En 2009, 53 bandes fleuries ont été suivies. 34 des 36 bandes situées au sud du sillon Sambre-et-Meuse (SSSM), qui avaient fait l’objet du suivi précédent, ont été revisitées à trois reprises. En complément de celles-ci, 19 nouvelles bandes (également implantée en 2006) ont été visitées pour la première fois au nord du sillon Sambre-et-Meuse (NSSM). Fort des expériences précitées, 2010 est considérée comme l’année de référence pour la standardisation de la méthodologie du suivi des lépidoptères. Dorénavant celui-ci comportera deux axes principaux : la continuation du suivi sur 20 bandes implantées en 2006 et le début d’un suivi de 20 bandes implantées en 2009. Ces suivis seront menés pendant cinq années à raison de quatre visites de terrain par an. 2011 est donc l’année « deux » du suivi lépidoptérologique utilisant le protocole standardisé l’année précédente. http://hdl.handle.net/2268/149397 Titre: Video multitracking and study of the collective behaviour in tadpoles <br/> <br/>Auteur, co-auteur: Delcourt, Johann http://hdl.handle.net/2268/149199 Titre: Feeding ecology and seed dispersal of a troop of pigtailed macaques (Macaca nemestrina leonina) at the Khao Yai National Park, Thailand <br/> <br/>Auteur, co-auteur: Latinne, Alice http://hdl.handle.net/2268/149198 Titre: Habituation et Contribution à l’étude de l’écologie d’une troupe de Macaques à queue de cochon, Macaca nemestrina, au sein du Parc National de Khao Yai, Thaïlande <br/> <br/>Auteur, co-auteur: Latinne, Alice http://hdl.handle.net/2268/148946 Titre: Diet composition of young and adult Northern Grey-headed Sparrow Passer griseus and adult Southern Red Bishop Euplectes orix in Burundi <br/> <br/>Auteur, co-auteur: Nasasagare, Régine Pacis; Ntakimazi, Gaspard; Libois, Roland <br/> <br/>Résumé: We studied the diet composition of Northern Grey-headed Sparrow Passer griseus and Southern Red Bishop Euplectes orix in four localities of the Rusizi Plain, northwest Burundi. We analyzed crop contents of 100 adults from each of the two species and the composition of food brought by parents to nestlings of the sparrow at ten nests. In all four sites, the sparrow’s diet consisted primarily of rice. The bishop also fed mostly on rice grains but also ate Lepidoptera caterpillars, some other insects and wild grass seeds such as Panicum sp. and Brachiaria sp. For adults of both bird species, there was no significant variation in diet throughout the year. However, the diet of young sparrows was much more diverse and changed from the day of hatching until fledging. On the day of hatching, chicks ate mainly caterpillars but by the tenth day, food items comprised one third caterpillars, one third Orthoptera and the rest of other insects including Odonata, Dictyoptera, Isoptera and adult Lepidoptera. After this and until fledging, the chicks were fed increasingly on rice seeds. Simultaneously, the proportion of caterpillars taken gradually decreased until none was fed to the nestlings at the end of the nestling period. The items brought by parents also varied with time of day, with caterpillars and grasshoppers in higher proportions in the morning, decreasing around mid-day and then increasing in the evening. http://hdl.handle.net/2268/148614 Titre: Computers As Genomic Time Machines for Meeting our Ancestors <br/> <br/>Auteur, co-auteur: Baurain, Denis http://hdl.handle.net/2268/148613 Titre: The African coelacanth genome provides insights into tetrapod evolution. <br/> <br/>Auteur, co-auteur: Amemiya, Chris T.; Alfoldi, Jessica; Lee, Alison P.; Fan, Shaohua; Philippe, Herve; Maccallum, Iain; Braasch, Ingo; Manousaki, Tereza; Schneider, Igor; Rohner, Nicolas; Organ, Chris; Chalopin, Domitille; Smith, Jeramiah J.; Robinson, Mark; Dorrington, Rosemary A.; Gerdol, Marco; Aken, Bronwen; Biscotti, Maria Assunta; Barucca, Marco; Baurain, Denis; Berlin, Aaron M.; Blatch, Gregory L.; Buonocore, Francesco; Burmester, Thorsten; Campbell, Michael S.; Canapa, Adriana; Cannon, John P.; Christoffels, Alan; De Moro, Gianluca; Edkins, Adrienne L.; Fan, Lin; Fausto, Anna Maria; Feiner, Nathalie; Forconi, Mariko; Gamieldien, Junaid; Gnerre, Sante; Gnirke, Andreas; Goldstone, Jared V.; Haerty, Wilfried; Hahn, Mark E.; Hesse, Uljana; Hoffmann, Steve; Johnson, Jeremy; Karchner, Sibel I.; Kuraku, Shigehiro; Lara, Marcia; Levin, Joshua Z.; Litman, Gary W.; Mauceli, Evan; Miyake, Tsutomu; Mueller, M.

The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution. http://hdl.handle.net/2268/148570 Titre: 15th Benelux Congress of Zoology abstract book <br/> <br/>Editeur scientifique: Colleye, Orphal; Dauby, Patrick; Fabri, Gregory; Frederich, Bruno; Lepoint, Gilles; Mauguit, Quentin; Plumier, Jean-Christophe http://hdl.handle.net/2268/148457 Titre: Evolution de la répartition de la loutre d'Europe (Lutra lutra) au Maroc <br/> <br/>Auteur, co-auteur: Libois, Roland; Rosoux, René; Fareh, Mostafa
