Abstract:

AbstractPopulations of the common hippopotamus Hippopotamus amphibius have undergone widespread decline as a result of habitat conversion and hunting for bushmeat and, increasingly, for ivory. North Cameroon holds important populations of large mammals, including the hippopotamus. The species' status and population trend are poorly known, and led CITES to suspend trade in hippopotamus trophies in 2013. Using the methodology of surveys conducted during 1976–1987, we conducted counts of the hippopotamus in Bénoué National Park during the wet season of 2011 and dry season of 2013, and drew on unpublished biannual density counts conducted by the Garoua Wildlife College, Cameroon, during 1989–2010. Counts along the 100 km stretch of the Bénoué River in the Park indicated a reduction from 400 individuals in 1987 to 188 in 2013. However, linear densities along a 15–32 km stretch in proximity to the Park headquarters and two tourist camps were constant during 1976–2013 (c. 3.7 individuals km−1). Hippopotamus distribution was negatively associated with the presence of the camps of gold diggers, which occupied the northern half of the Park. Observations of antelopes suggested they had a comparable distribution, unlike primates, which were distributed relatively evenly. Our results show the importance of year-round conservation presence in the Park, which could be achieved with adequate personnel, a functional road system, and reinforcement of operations in neighbouring sport-hunting areas.

Abstract:

Abstract:We studied the effects of savanna fires on the structure of local ungulate communities in a West African woodland savanna. The distribution of 11 ungulate species over 9−15 burned sites (the number of which increased as burning activity continued during the dry season) and 7−13 unburned sites was compared with a variety of null models or randomized ‘virtual communities’. Five different parameters of community structure were examined: body mass distribution, co-occurrence patterns, species richness, species density and guild dominance. Overall, ungulate species were not randomly distributed over burned and unburned sites. The regular spacing of body masses in the set of species recorded on burned and unburned sites indicated competition, since species similar in body mass are more likely to compete than species of different size. However, co-occurrence patterns on burned sites were random, indicating absence of competition at fine spatial scales due to differential habitat use within the burned landscape. Although the attractiveness of the regrowth on burned sites resulted in higher numbers of ungulates compared with unburned sites, species richness was not different. Grazers were the dominant guild on burned sites, but there were no differences in species richness or species density between grazers and browsers on unburned sites.

Abstract:

A mathematical model is applied to the Aoste Valley (Italy), which is a good example of the hydrological workings of alluvial rock basin aquifers in mountainous regions. The course of the Dorea Baltea follows the valley, which between the altitudes of 500 and 600 m is dominated by summits reaching more than 3000 m. The lacustrine- and fluviatile-type sedimentary deposits are accompanied by several alluvial cones that, due to their varying nature, confer very diverse hydrodynamic characteristics to the land. In this particular context, the source and drainage of the Dorea control the hydrodynamics of the aquifers and influence the spatial dispersion of the physicochemical properties of the groundwater. The model also led to quantify and determine the zones and types of exchanges with the river. Simulation of lowering the water table in the river showed the variable sensitivity of the water table piezometry with various spatial impacts. Finally, the streamaquifer impact is highlighted by the spatial evolution of the sulphate contents coming from deep lateral sources. Taking into account the streamaquifer exchanges in an underground-flow mathematical model gives a better understanding of the workings of the valley aquifers and thus their management, especially for the development of watercourses in mountainous regions.[Journal translation]

Abstract:

In recent years, wildlife policies that consider the participation of stakeholders have been promoted. An understanding of the stakeholders' attitudes towards conservation and existing policies are critical in designing new policies or sustainable conservation strategies. This paper examines stakeholders' (local people, park staff and professional hunter guides) attitudes, towards the Bénoué Wildlife Conservation Area (BWCA) and towards Cameroonian wildlife policy. The BWCA encompasses the Bénoué National Park and its surrounding hunting concessions that also include some villages. Both the Park and the hunting concessions are two categories of protected areas. Data were collected using informal interviews and questionnaires administered to 114 households from three communities, 17 park staff and seven professional hunter guides. Local people's attitudes towards protected areas depended on the management category of the particular protected area. Local people were positive towards the existence of the Park, but negative towards the system of hunting concession areas. There was local variation between communities concerning these attitudes. Local people were generally positive to maintaining the present Park area, but preferred a reduction in the size of the hunting concessions. Both Park staff and professional hunter guides expressed concern about present management strategies and the extent of illegal resource exploitation. Despite having poor knowledge of the current Cameroonian wildlife policy, most of the local households expressed support for it, but called for increased local involvement in management, off-take and the harvesting of benefits from both Park and hunting concession activities. The Park staff were sceptical about local participation in this context and saw such endeavours as a threat to a sound biodiversity management scheme. The findings indicate the need to strengthen current wildlife policy, promote the involvement of local people and empower the Park staff, both in terms of resources and in terms of skills in interacting with local people. The revised policy should be designed so as to vary according to the category of protected area and allow site-specific adaptations. Local people must experience reduced incurred costs and increased incomes from the Park. An environmental education programme is recommended to extensively disseminate the policy to user groups in the area.

Abstract:

Résumé Au cours de l'été 1995, la distribution des concentrations atmosphériques en dioxyde d'azote (NO 2 ) et enozone (O 3 ) a été analysée dans une vallée alpine (Chamonix, France). Sur 8 km, du fond de la vallée (1 020 m) à 2 000 m d'altitude, 42 sites répartis selon une maille de 1 km 2 ont fait l'objet de trois échantillonnages passifs hebdomadaires, du 17 juillet au 7 août 1995. Des mesures en continu des concentrations en NO 2 et en O3 effectuées simultanément sur deux des sites ont permis de vérifier les résultats obtenus par l'échantillonnage passif. Les concentrations en NO 2 s'atténuent graduellement du sud-ouest au nord-est suivant l'axe de la vallée, passant de 50,3 à 9,9 [.mu]g/m 3 . Par contre, elles diminuent rapidement avec l'altitude (de 27,3 [.mu]g/m 3 au fond de la vallée à 3,2 [.mu]g/m 3 à 2 000 m d'altitude). Les concentrations maximales sont relevées à proximité des zones de concentration du trafic routier: route principale (26 000 véhicules par jour), route d'accès au tunnel du Mont-Blanc (7 000 v/j) et aires de stationnement. L'ozone est en concentration maximale en altitude (125 [.mu]g/m 3 ) et diminue graduellement vers le fond de la vallée (67,1 [.mu]g/m 3 ). Le resserrement de la vallée dans la partie nord-est conduit à l'augmentation des concentrations dans cette zone. Le climat (turbulences de l'air, phénomènes d'inversion thermique), les phénomènes photochimiques et la configuration de la vallée sont les facteurs expliquant ce patron de distribution des concentrations en NO 2 et en O 3 dans la vallée.

Abstract:

Les espaces pastoraux subissent des régressions et des conquêtes de par le monde. Ceux-ci occasionnent la diminution assez large de la quantité et de la qualité des fourrages encore disponibles. Cette étude a été réalisée dans le but d’évaluer qualitativement les espèces fourragères présentes au sein du département de la Bénoué. La méthode utilisée pour l’identification des espèces fourragères (herbacées et ligneuses) se base sur les différents entretiens menés auprès des éleveurs de ruminants, par le suivi des bovins, caprins et ovins au pâturage et par l’utilisation des clés d’identification disponibles. Les résultats montrent que les zones de pâturages existantes, diffèrent en qualité floristique et selon la localité où l’on se retrouve. En plus, plusieurs essences fourragères existent et appartiennent à environ 41 espèces. Parmi la vingtaine d’espèces fourragères appréciées par le bétail, 05 ligneuses le sont encore plus (Prosopis africana, Daniella oliveri, Acacia sieberiana, Stereospermum kunthianum et Balanites aegyptica). Il en est de même des 02 herbacées : Acroceras amplectens et Pennisetum pedicellatum. Plus d’une dizaine se retrouve en voie de disparition/menacées de nos jours. Si rien n’est fait, dans quelques années on observera une diminution de la richesse floristique en termes de ressources fourragères dans les différentes localités. Par ailleurs, une étude portant sur les éléments nutritifs et une étude quantitative de ces espèces fourragères rencontrées doivent être menées, pour mieux enserrer les espèces à conserver et les meilleurs espaces offrant de meilleures ressources fourragères.Mots clés : Zones de pâturage, richesse floristique, éleveurs de ruminants, clés d’identifications. English Title: Qualitative assessment of fodder species present in the Bénoué division (North Cameroon)Pastoral land (areas) worldwide are undergoing rapid decline as a result of urbanization (development). This often leads to a large decrease in the quantity and quality of available fodder. This study was aimed at evaluating quantitatively the various fodder species present within the Bénoué division. The method used for identification of fodder species (herbaceous and ligneous) was through interviews (surveys), conducted with animal-grazers (breeders) pasturing their flocks (cattle, goats and sheep) in the field and using available keys for fodder for pinpointing. The existing pastoral areas (zones), varies in quality and quantity of flora depending on the location where it is found. Several fodder species exist, belonging to about forty-one (41) classes of species. Among the twenty (20) fodder species best valorized by livestock, five (5) ligneous are most preferred (Prosopis africana, Daniella oliveri, Acacia sieberiana, Stereospermum kunthianum et Balanites aegyptica). As for the herbaceous, same is true for two (2) species, Acroceras amplectens et Pennisetum pedicellatum. More than a dozen species happen to be endangered. Thus, if nothing is done in a few years in order to conserve and preserve these endangered species they might become threatened as a result of gradual reduction in terms of their flora abundance within the different localities. In addition, a study relating to the nutritive elements and a quantitative study of these fodder species met must be undertaken, for better enclosing the species to be preserved and best spaces offering of better fodder resources.Keywords: Pastoral areas, flora abundance, livestock grazers, keys of identifications.

Abstract:

From 1948–1952, Rudy Vallée, a successful performer whose career spanned radio, film, recorded music and stage entertainment, expanded his operations into the burgeoning US television market with the launch of his independent production company, Vallée Video. One of hundreds of forgotten companies that arose during this period to meet growing demand for programming content, Vallée Video offers an important case study for understanding animation workers’ role in postwar television production. Drawing on corporate records and films preserved in the Rudy Vallée Papers at California’s Thousand Oaks Library and the UCLA Film and Television Archive, the authors’ analysis documents Vallée’s use of freelance artists and external animation houses for work ranging from camera effects for illustrated musical shorts to animated commercials and original cartoon series. These productions demonstrate the fluid movement of animation labor from theatrical film to small screen markets and participated in larger aesthetic shifts toward minimalist drawing styles and limited character animation that would soon dominate mid-20th century US television.

RÉSUMÉLes analyses pollinique et macrofossile de sédiments de deux lacs des environs de Mont-Saint-Pierre (Gaspésie), l'un dans la vallée côtière, l'autre sur le plateau, permettent de reconstituer l'histoire postglaciaire de la végétation dans deux situations physiographiques contrastées. Seul le plateau a été colonisé par une végétation initiale de type toundra (> 10 400 ans BP), pendant que la vallée était encore en partie ennoyée par la mer de Goldthwait. L'afforestation du plateau fut caractérisée d'abord par des populations de Picea sp., accompagné de Populus sp. et Larix laricina, puis par un envahissement progressif par Abies balsamea et Betula papyrifera. La baisse de la représentation pollinique de l'aulne vert (Alnus cf. crispa), maximale durant l'afforestation, paraît être un indicateur assez fidèle de la fermeture de la couverture forestière. Cette phase se termine vers 9000 ans BP sur le plateau. Le rythme de l'afforestation a été différent dans la vallée. Des taxons héliophiles s'y sont maintenus plus longtemps, ce qui peut être relié à l'activité des versants abrupts qui flanquent la vallée. Malgré des variations de l'abondance relative des arbres, la sapinière à bouleau blanc a sans doute occupé le plateau depuis 9000 ans BP environ. Par contre, la végétation de la vallée s'est passablement modifiée jusque vers 5000 à 4500 ans BP, par la migration successive de Betula alleghaniensis, de Pinus strobus, de Fraxinus nigra, dAcer saccharum et d'Ulmus americana. L'implantation progressive de ces arbres relativement thermophiles est à l'origine de la diversité du paysage actuel de la vallée. Ces reconstitutions permettent d'écarter l'hypothèse de Dansereau (1944) selon laquelle les érablières à Acer saccharum de la Gaspésie seraient des groupements hérités de l'optimum climatique de l'Holocène moyen, au cours duquel les érablières auraient été largement répandues sur le territoire. Les données montrent que ces érablières datent de l'Holocène Supérieur, la migration d'Acer saccharum ayant sans doute été freinée par des barrières topo-climatiques entraînant une discontinuité prononcée des habitats pouvant accueillir cette espèce.

Abstract:

The de la Vallée Poussin standard orientation density function νκ(ω)=C(κ)cos⁡2κ(ω/2) is discussed with emphasis on the finiteness of its harmonic series expansion which, advantageously distinguishes it from other known standard functions. Given its halfwidth, the de la Vallée Poussin standard orientation density function allows, for example, to tabulate the degree of series expansion into harmonics required for its exact representation.
