Abstract:

SummaryThe montane forests of western Cameroon are well known for their endemic birds. The most northerly such forests probably occur on Mt Tchabal Mbabo, where a preliminary survey of the avifauna in 1990 found 12 montane species, of which six represented significant range extensions, among them the threatened Ploceus bannermani. Given the increasing human pressures on other montane forests in Cameroon, Mt Tchabal Mbabo may be attractive for future conservation because of its comparative lack of human disturbance. Densities of indigenous people are low and there is a lack of significant hunting and firewood-gathering, the precipitous nature of the northern slope makes human intrusions difficult, and the lack of human disturbance may mean that local animal populations are stable.Les forêts d'altitude de l'ouest du Cameroun sont bien connues pour leurs populations endémiques d'oiseaux. Les forêts les plus au nord sont celles du Mont Tchabal Mbabo, où un recensement préliminaire de la faune aviaire en 1990 a révélé 12 espèces, dont six avaient une aire de répartition relativement grande, y compris l'espèce menacée Ploceus bannermani. Etant donné l'accroissement des pressions humaines sur les autres forêts d'altitude au Cameroun, le Mont Tchabal Mbabo pourrait se réveler intéressant pour des programmes de conservation futurs, compte tenu d'une perturbation humaine relativement inexistante. Les densités de population indigène y sont faibles, et la chasse ainsi que le ramassage du bois pour les besoins domestiques ne sont pas significatifs. Les pentes abruptes du nord rendent difficile toute intrusion humaine, et l'absence de perturbations dues à l'homme pourrait signifier la stabilité des populations animales locales.

Abstract:

Prunus africana (Hook. f.) Kalkman est une plante de haute valeur médicinale qui connait de forte pression d’exploitation au Mont Cameroun. Dans le cadre d’une récolte durable des écorces, deux méthodes d’exploitation (2/4 et 4/8 opposées) ont été recommandées par l’Agence National de Développement des Forêts (ANAFOR) qui est l’autorité scientifique CITES du Cameroun. Cette étude porte sur l’analyse de la soutenabilité biologique et économique de ces méthodes de récolte en vigueur Cameroun. Un inventaire d’exploitation au taux de sondage de 100% dans une parcelle de 100 ha en fin de première rotation (cycle de 5 années), a servi à la collecte des données sur l’état de santé des arbres (mort, vivant, dépérissant), la mesure des diamètres à hauteur de poitrine et le dénombrement de la population d’arbre. Au total 170 arbres ont été dénombrés, ce qui correspond à 1,7 tiges/ha. Dans cet échantillon on compte 84 arbres (54%) exploités à la méthode 4/8. Ce groupe comprend 23 arbres dépérissant (27,40%), 7 arbres morts (8,30%) et 54 arbres vivants (64,30%). Tandis que sur un effectif de 86 arbres (56%) exploités par la méthode 2/4 on a observé 12 arbres dépérissant (14%), aucun arbre mort et 74 arbres vivants (86%). Ces informations montrent que la méthode d’écorçage (4/8) est plus compromettante sur la croissance des populations d’arbre. Elle est également économiquement la moins rentable avec des pertes de 1650 $US comparée à la méthode 2/4 (660 $). La méthode 2/4 a un faible impact sur la santé des arbres, elle peut être améliorée et adoptée comme méthode de récolte durable qui garantit une cicatrisation rapide de l’écorce des arbres et des revenues importants.Mots clés : Plante médicinale, méthode de récolte durable, régénération, aménagement des ressources forestières, Mont Cameroun. English Title: Comparative analysis of the sustainability of prunus africana (Hook. f.) Kalkman harvesting techniques used in Cameroon: biologic and socioeconomic incidence Prunus africana (Hook. f.) Kalkman is a medicinal plant with a high socioeconomic value which is facing serious bark harvesting pressure in Mount Cameroon. To ensure sustainable exploitation, two norms (2/4 and 4/8 opposites) was prescribed by the National Forestry Agency (ANAFOR) which is the CITES scientific authority in Cameroon. This study analyzes the biologic and economic sustainability of these harvesting practices. Data collection consisted of trees inventory, measurement of trees diameter and appreciation of tree vitality within a 100 ha plot at the end of the first rotation (five years later after bark harvesting). The sample comprise 170 trees (corresponding to 1.7 trees/ha) amongst which 84 trees (54%) were harvested using 4/8 technic. In this group, 23 (27.40%) trees were found in bad health, 7 (8.30%) trees dead, 54 trees alive (64.30%) and the annual diameter increment was 0.42±0.37 cm while in a group of 86 trees (56%) harvested with 2/4 technic, observation shown: 12 trees (14%) in bad health, 74 trees alive (86%) and annual diameter increment of 0.44±0.36 cm. This statistic shows that, 4/8 technic has a negative impact on trees population and is less benefit with losses estimated at 1650 $US comparing to 660 $US (2/4 technic). The 2/4 technic can be improved and adopted as a suitable harvesting method; since it ensures a fast diameter recovery, low impact on trees population and generate more income.Keywords: Medicinal plant, sustainable harvesting techniques, regeneration, forest resources management, Mount Cameroon.

Abstract:

Les Loranthaceae constituent des ressources précieuses pour les populations locales africaines. Cependant, peu d’ethnies connaissent l’importance socio-économique des Loranthaceae de par le manque d’études ethnobotaniques sur ces espèces. Afin de contribuer à la valorisation et à la gestion durable des Loranthaceae parasites des plantes ligneuses, une approche associant deux méthodes a été adoptée. L’une, basée sur des relevés de surface et l’autre sur une enquête ethnobotanique relative aux connaissances locales des Loranthaceae dans 9 Arrondissements de la Région de l’Extrême-Nord du Cameroun. Au total, 4 genres (Agelanthus, Globimetula, Phragmanthera et Tapinanthus) et 7 espèces parasites (Agelanthus dodoneifolius, Globimetula braunii, Phragmanthera capitata, Tapinanthus bangwensis, T. belvisii, T. globiferus et T. ophiodes) ont été inventoriés et identifiés dans les Monts Mandara. Il ressort aussi que ces espèces parasites sont utilisées en pharmacopée dans des recettes médicinales et magico-religieuses (45,56%), pour traiter des infertilités (32,70%) et des troubles mentaux (32,36%). Les résultats ont aussi montré que Mangifera indica (35,74%) et Senna singueana (34,41%) sont les hôtes des parasites les plus sollicités. Aussi ont-ils révélé que la commercialisation des Loranthaceae constitue une source de revenu économique et une ressource importante en pharmacopée pour les populations locales des Monts Mandara. Ces résultats pourraient servir de référence pour la recherche de stratégies d’exploitation et de conservation durable de cette diversité végétale.Mots clés : Loranthaceae, Espèces parasites, pharmacopée, Monts Mandara, Cameroun. English Title: Diversity and socio-economic importance of Loranthaceae parasites of woody plants of Mandara Mountains in the Far-North Region, Cameroon Loranthaceae are valuable resources for local African populations. However, few ethnic groups know the socio-economic importance of Loranthaceae due to the lack of ethnobotanical studies on these species. In order to contribute to the enhancement and sustainable management of Loranthaceae parasites of woody plants, an approach combining two methods was adopted. One, based on surface surveys and the other on an ethnobotanical survey relating to local knowledge of Loranthaceae in 9 Subdivisions of the Far North Region of Cameroon. In total, 4 genera (Agelanthus, Globimetula, Phragmanthera and Tapinanthus) and 7 parasitic species (Agelanthus dodoneifolius, Globimetula braunii, Phragmanthera capitata, Tapinanthus bangwensis, T. belvisii, T. globiferus and T. ophiodes) have been inventoried on the Mandara Mountains. It also appears that these parasitic species are used in pharmacopoeia in medicinal and magico-religious recipes (45.56%), to treat infertility (32.70%) and mental disorders (32.36%). The results also showed that Mangifera indica (35.74%) and Senna singueana (34.41%) are the hosts of most solicited parasites. They also revealed that the commercialisation of Loranthaceae constitutes a source of economic income and an important resource in pharmacopoeia for the local populations of the Mandara Mountains. These results could serve as a reference of strategies for the sustainable exploitation and conservation of this plant diversity.Keywords: Loranthaceae, parasitic species, pharmacopoeia, Mandara mountains, Cameroon.

Abstract:

Abstract Hypertension is a global public health challenge, but awareness, treatment, and control rates remain low. May Measurement Month (MMM) creates a platform for awareness creation and opportunistic screening which can identify significant numbers with raised blood pressure (BP). We present results of the 2018 edition of MMM in Cameroon. A cross-sectional survey of self-selected volunteers aged ≥18 years was conducted in May 2018. The definition of hypertension and statistical analyses followed the standard protocol. Data were collected from 28 public (indoors and outdoors) and private locations which were assigned unique site identification numbers, over a 30-day period. Of the 8883 participants screened, 53.8% were male and the median age was 35 (interquartile range 21) years, and 30.0% reported not having a previous BP measurement. After imputation, 1867 (21.0%) were hypertensive, 645 (34.5%) were aware of their diagnosis, and 507 (27.2%) were on antihypertensive medication, among whom 242 (47.8%) had controlled BP. In linear regression models adjusting for age, sex, and the use of antihypertensive medication, systolic and diastolic BP were significantly higher in participants aware of their diagnosis, those on antihypertensive medication, and who reported alcohol intake of 1–3 times per month and, one or more times per week. Hypertension prevalence is the lowest, and awareness, treatments, and control rates the highest reported in epidemiological studies in Cameroon in the last two decades. Further surveys will be useful in evaluating the impact, if any, of the MMM campaign on the burden of hypertension in the Cameroon.

Abstract:

Studies investigating imitation are usually conducted with adult models in Western contexts; therefore, the influence of cultural context and the model’s age on infants' imitation is largely unknown. This study assessed deferred imitation in 9-month-old infants from the German middle-class ( N = 44) and the ethnic group of Nso in rural Cameroon ( N = 43). Infants either received an adult or an older child as a model. Moreover, the test material comprised varying degrees of target action difficulty. Across cultures and target actions infants imitated more when an adult model demonstrated the target actions. However, results revealed that infants did not show an adult model advantage for easier target actions, but only for those that were considered more difficult.

Abstract:

The Mayer-Rokitansky-Küster-Hauser syndrome is the congenital absence or underdevelopment of the uterus and vagina even though the external genitalia, ovaries and ovarian function are normal. This condition is uncommon in Cameroon. A 23-year-old woman of the Fulbé tribe, a predominantly Islamic tribe of the northern part of Cameroon, complained of the absence of menstruation after age of puberty and lower abdominal pain occurring almost at the same period every month. She has been married polygamously for 10 years and has been having normal, satisfactory sexual intercourse. The sonographic and laparoscopic findings of this patient were consistent with Mayer-Rokitansky-Küster-Hauser syndrome. The patient was counseled for in vitro fertilization and surrogacy. Patients with Mayer-Rokitansky-Küster-Hauser syndrome typically present with primary amenorrhea during adolescence. With the existing medical technology in Cameroon, this condition is easily accessible in tertiary healthcare facilities. Patients with Mayer-Rokitansky-Küster-Hauser syndrome could become mothers through in vitro fertilization and surrogacy, but the cost is prohibitive in Cameroon.

Abstract:

Background: To accelerate access to pediatric HIV care in Cameroon, operational challenges in implementing HIV pediatric care need to be identified. The aim of this study was to assess the knowledge, attitudes, and practices of health care workers regarding pediatric HIV infection in Cameroon. Methods: A descriptive cross-sectional study was conducted over a 4-month period (April to August 2014) in 12 health facilities in 7 regions of Cameroon selected using systematic random sampling. Data were collected from interviews with health care providers and managers using standardized self-administered questionnaires and stored in the ACCESS software. Results: In total, 103 health care providers were included in this study, of which 59 (57.3%) were health workers and 44 (42.7%) community agents. Most of the health workers in charge of HIV pediatric care were nurses, requiring effective medical task shifting that was institutionalized in Cameroon. The knowledge of health care providers in relation to pediatric HIV care was acceptable. Indications for prescription of test for early infant diagnosis were known (96.1%), but their attitudes and practices regarding initiating antiretroviral therapy (ART) in infants less than 2 years (5.2%) and first-line ART protocols (25.4%) were insufficient, due to little information about standard procedures. Conclusion: Capacity building of health care providers and large-scale dissemination of normative national documents are imperative to improve HIV pediatric care in the health care facilities.

Abstract:

Abstract The multi-country May Measurement Month (MMM) screening campaign aims to raise awareness on blood pressure (BP) and hypertension in individuals and communities, and measure BP, ideally, of those who had no BP measurement in the preceding year. We here report key findings from the Cameroon arm of MMM 2019. An opportunistic sample of adults (≥18 years) was included from 5 May to 5 June 2019 across 15 sites (markets, churches, homes, motor parks, workplaces, and hospitals/clinics). Data collection, cleaning, the definition of hypertension, and statistical analysis followed the standard protocol. The mean age of the 30 187 participants screened was 36.9 (SD: 14.9) years, 50.4% were female (5% of whom were pregnant), and 94.4% were screened out of the hospital/clinic settings. After multiple imputation of missing data, 6286 (20.8%) had hypertension, 24.0% were taking antihypertensive medication, and 705 (11.2%) of all participants with hypertension had controlled BP. In linear regression models adjusted for age, sex, and antihypertensive medicines use, a previous diagnosis of hypertension, a history of stroke, and use of antihypertensive medicines were significant predictors of systolic and diastolic BP levels. BPs were also significantly higher when measured in public outdoors, public indoors (diastolic BP only), workplaces, and other unspecified areas compared to hospitals/clinic settings. MMM19 is the largest ever BP screening campaign in a single month, in Cameroon and despite the limitations resulting from non-random sample selection, the opportunistic screening allows access to awareness and screening for hypertension out of the hospital/clinic settings.

Abstract:

Since March 2020, the Cameroonian government implemented nationwide measures to stall COVID-19 transmission. However, little is known about how well these unprecedented measures are being observed as the pandemic evolves. We conducted a six-month online survey to assess the preventive behaviour of Cameroonian adults during the COVID-19 outbreak. A five-point adherence score was constructed based on self-reported observance of the following preventive measures: physical distancing, face mask use, hand hygiene, not touching one’s face, and covering the mouth when coughing or sneezing. Predictors of adherence were investigated using ordinal logistic regression models. Of the 7381 responses received from all ten regions, 73.3% were from male respondents and overall mean age was 32.8 ± 10.8 years. Overall mean adherence score was 3.96 ± 1.11 on a scale of 0–5. Mean weekly adherence scores were initially high, but gradually decreased over time accompanied by increasing incidence of COVID-19 during the last study weeks. Predictors for higher adherence included higher age, receiving COVID-19 information from health personnel, and agreeing with the necessity of lockdown measures. Meanwhile, experiencing flu-like symptoms was associated with poor adherence. Continuous observance of preventive measures should be encouraged among Cameroonians in the medium- to long-term to avoid a resurgence in COVID-19 infections.

Abstract:

AbstractThe forests of the Cameroon-Nigeria transboundary region have been highlighted as a high conservation priority, yet many of the extant forest remnants remain relatively unknown, particularly with regard to the occurrence of large mammals. Between 2002 and 2004 we surveyed the large mammal fauna of the Mone and Ejagham Forest Reserves and the Upper Banyang, Nkwende Hills and Etinde forests of south-west Cameroon. Our objective was to document the extant large mammal species as an important step in the review of government priorities to identify key sites within the region for conservation and management. We reviewed the available literature on mammal distribution and then surveyed the forests for mammal and human signs. Despite a growing illegal commercial trade in wildlife, particularly for bushmeat, many sites retain populations of one or more threatened and locally rare large mammal species of significant conservation importance. Moreover, the sites collectively complement each other in terms of their representation of the threatened large mammal fauna. An emphasis on the enforcement of wildlife legislation and minimizing logging impact are of primary importance for the conservation of large mammals in these and other forest remnants in south-west Cameroon. In addition, at some sites, there already exists community interest in active wildlife management.

Abstract:

RicinodendronheudelotiiBail., commonlyknown as Njansang, is a speciesendemic to the dense evergreenforests of Africa. Its fruits are highlyprized and are usedboth for home consumption and for marketing in Cameroon and in the Congo Basin in general.This studyaims to evaluate fruit production of thisspeciesunder the influence of two types of land use. To do this, itwasconducted in the bimodal rainfallforest zone located in the Central region (Cameroon) between the months of August and October of the years 2017 to 2019.Thus, individuals of R. heudelotiiwereidentified and their fruit production wasevaluated in agroforestry plots based on cocoatrees and in more or lessdegradedforests.The resultsobtainedshowedthat the fruit production per plant of Njansangis 8.34 Â± 7.45 kg per year.It did not varysignificantlyfromyear to year, but wassignificantlyhigher in September.Moreover, itwassignificantlyhigher in cocoa agro-foreststhan in weaklydisturbedforests.Theseresultscould help forecastharvests and production sales for the month or year.Also, theycouldstimulate the introduction and integration of R. heudelotiiindividualsintococoa agro-forestrysystems and thusboost domestication, development of the species and the diversification of agroforestry production systems.

Abstract:

In this paper, the work consists of categorizing telecommunication base stations (BTS) for the Sahel area of Cameroon according to their power consumption per month. It consists also of proposing a model of a power consumption and finally proceeding to energy audits in each type of base station in order to outline the possibilities of realizing energy savings. Three types of telecommunication base stations (BTS) are found in the Sahel area of Cameroon. The energy model takes into account power consumption of all equipment located in base stations (BTS). The energy audits showed that mismanagement of lighting systems, and of air-conditioning systems, and the type of buildings increased the power consumption of the base station. By applying energy savings techniques proposed for base stations (BTS) in the Sahel zone, up to 17% of energy savings are realized in CRTV base stations, approximately 24.4% of energy are realized in the base station of Missinguileo, and approximately 14.5% of energy savings are realized in the base station of Maroua market.

Abstract:

Background. The endemic nature of the hepatitis B virus (HBV) in Sub-Saharan Africa is a significant public health problem that places health care providers (medical students inclusive) at increased risk of occupational exposure. However vaccination against HBV is not systematic among medical students in Cameroon. Thus, we sought to evaluate awareness and HBV vaccine coverage among medical students in Cameroon. Methods. Using semistructured questionnaire and a cross-sectional approach, medical students from 3 State Universities in Cameroon were evaluated for their knowledge, attitudes, and vaccination status against the HBV. Data were collected over a 3-month period. HBV vaccine status was defined as complete (3 doses), partial (1 and 2 doses), and unvaccinated. Data were entered and analyzed using Epi-info 7. Results. There were 714 respondents among whom 186 (26.05%) had been vaccinated at least once against HBV. Sixty-six (9.24%) were partially vaccinated and 120 (16.81%) completely vaccinated. No student had done postvaccination serologic testing to confirm full immunisation. Eighty-three percent (83.00%) of respondents had adequate knowledge on HBV infection and vaccine, while 90.00% had adequate knowledge on HBV transmission. Most medical students had a positive attitude towards the HBV vaccine. The most common negative attitudes were worries about the side effects and fears of being infected by the vaccine. Conclusion. Despite adequate knowledge on HBV infection and vaccination only about 1 in 6 medical students had completed the HBV vaccination series. This highlights the need for better health policies aimed at increasing access and coverage of the HBV in at-risk populations like medical students.

Abstract:

A pesar de un modesto resurgimiento del sector turístico en Camerún durante la última década, actualmente los apoyos que ofrece el estado camerunés en este ámbito son más que limitados, habiendo sufrido un recorte considerable tanto a nivel de soporte logístico a través del desarrollo de infraestructuras, como en cuanto a aportaciones económicas y subvenciones directas se refiere. El objetivo de nuestro estudio es descubrir el potencial turístico del Parque Nacional del Monte Camerún, en la Región Suroeste del país, y determinar al mismo tiempo las dificultades de los colectivos de trabajadores que orientan su actividad profesional hacia el ecoturismo dentro de dicho espacio natural. Optando por una metodología de observación participante sobre el terreno, y contrastando nuestros datos mediante una revisión bibliográfica y documental sobre la realidad estudiada, llegaremos a comprender cómo el potencial turístico de la zona es considerable, valorando la riqueza de sus recursos naturales, y de forma paralela identificaremos las dificultades de los colectivos locales para lograr desarrollarse y permitir una mejora en sus condiciones laborales, revelando un grado de coordinación y organización interna de estos colectivos muy limitado. Como conclusiones destacamos entre otras que la oferta de iniciativas de turismo sostenible en la región es en gran medida apoyada por organizaciones y entidades extranjeras, las cuales ayudan a promocionar el potencial turístico de esta zona del Camerún, ya de por si con un patrimonio natural extraordinario, aportando un cierto flujo de visitantes que mantiene vivo el ecoturismo en la región, pero sin reforzar esta colaboración entre agentes locales e iniciativas exteriores, la supervivencia del turismo ecológico como motor de desarrollo sostenible a nivel local podría verse gravemente amenazada.

Abstract:

Ce travail porte sur l’évaluation du potentiel des images multi-temporelles et multi-capteurs (optique et radar) des satellites Sentinel 1 et 2 pour la cartographie de l’occupation du sol et le suivi de l’évolution du trait de côte dans un écosystème tropical sur la période 2015 à 2020. La zone d’étude choisie est l’Estuaire du Cameroun. Cette zone représente un milieu de transition écologique majeur dans la sous-région avec la présence de réserves naturelles protégées (mangroves, forêt dense, zones humides) mais aussi une forte activité anthropique (constructions, agriculture, forêt dégradée). L’approche méthodologique a consisté en une chaine de prétraitements et d’analyses visuelles d’images, suivie d’une combinaison des bandes de chaque capteur, d’une classification supervisée Random Forest pour ébaucher une cartographie de l’occupation du sol et enfin une numérisation du trait de côte. Globalement, les résultats montrent que la classification, avec les images Sentinel 2 en utilisant 10 bandes et en ajoutant 4 indices de végétation, s’avère légèrement plus précise (95.75%) que celle issue des 13 bandes initiales (91.78%). La classification avec les seules images Sentinel 1A double polarisation (VV, VH) conduit à une précision de 78.44%. La combinaison des bandes Sentinel 2A (10 bandes et 4 indices) et Sentinel 1 améliore les résultats et conduit à une précision de 98.76%. Nos résultats montrent aussi que l’utilisation des séries chronologiques d’images multi-temporelles améliore considérablement la précision de classification par rapport à l’usage d’une seule image (mono-date), et cela pour les deux capteurs, soit un gain supplémentaire de 13% et 10% respectivement pour Sentinel-2 et Sentinel-1. Néanmoins ce gain reste faible pour les classes temporellement stables. Les résultats d’analyse de l’évolution du trait de côte montrent que l’estuaire du Cameroun est perturbé selon différents niveaux d’érosion (Cap Cameroun, Partie Nord île Manoka, embouchure de la Sanaga), et d’accrétion (Limbé, et Partie Sud île Manoka) et aussi par de faible variations internes. La fusion des données de télédétection optique et radar dans la discrimination des classes d’occupation du sol, a permis de montrer que les zones de constructions sont les plus vulnérables à l’érosion côtière. Par contre, la présence de la végétation (mangrove, forêt) stabilise et protège la côte d’éventuels risques de cette nature.

Abstract:

Tree litter fall was monitored for 2 years in two Terminalia ivorensis A. Chev. plantations in the humid tropics of southern Cameroon. The plantations were 6 and 17 years old when they were each thinned to two timber stand densities (TSD) and understorey food crops were introduced. Leaf litter was the predominant litter fraction in all treatments. Treatment means of specific leaf area for T. ivorensis ranged from 83.7 to 100.7 cm2·g-1. Litter-fall production, leaf area per tree, and leaf area index for T. ivorensis were all higher in year 2 than in year 1. There was near complete defoliation of the T. ivorensis stand by Epicerura sp. (Lepidoptera: Notodontidae) caterpillars in the month just before the start of litter-fall sampling. This is the first report of an Epicerura sp. from Cameroon. Terminalia ivorensis leaf litter production per tree, specific leaf area, and leaf litter nutrient concentrations showed few significant differences between TSD treatments. This lack of response suggests that T. ivorensis is a suitable species for growing at stand densities lower than is normal silvicultural practice in association with food crops.

Abstract:

In 2010 the New York Times reported that ‘[t]ribes of Amazon Find an Ally Out of “Avatar”’, James Cameron. The alliance was against the building of Belo Monte, a hydroelectricdam in the Xingu River in Brazil. Cameron made a documentary about Belo Monte, A Message from Pandora. Here he states that Avatar becomes real in the struggle against the dam. This appears to confirm U. K. Heise’s observation that the ‘Amazon rainforest has long functioned as a complex symbol of exotic natural abundance, global ecological connectedness, and environmental crisis’. This construal, however, downplays the ‘symbols’ cultural components. In this article I show that the image of an ecological ‘rainforest Indian’ and a particular kind of culture constitutes a crucial part of the Amazon as ‘a complex’ cross-disciplinary ‘symbol’. Firstly, I examine how an Amazonian topology (closeness to nature, natural cultures) is both a product of an interdisciplinary history, and a place to speak from for ethno-political activist. Next I analyze how Amazonian cultures have been turned into ‘ethnological isolates’ representing a set of grand theoretical problems in anthropology, not least concerning the nature/culture-distinction, and how environmentalism has deployed the same topology. Finally I examine how Avatar and one of its cinematic intertexts, John Boorman’s The Emerald Forest, is used as a model to understand the struggle over the Belo Monte. In a paradoxical way the symbolic power of indigenous people in ecological matters here appears to be dependent upon a non-relation, and a reestablishment of clear cut cultural boundaries, where ‘the tribal’ is also associated with the human past. Disturbingly such symbolic exportation of solutions is consonant with current exportations of the solution of ecological problems to ‘other places’.

Abstract:

The diurnal primate community of the Korup area of south-west Cameroon is rich in species and high in endemism. Two years monitoring in the Support Zone around Korup National Park have shown that, although all species of the original community are still present, Preuss' red colobus and drill, which were considered to be threatened in the early 1990s, have declined further and are probably facing local extinction. Densities of the crowned monkey also seem to have declined. Only mona and putty-nosed monkeys have an expanded distribution, and densities that are within the range of those reported from previous studies in the region. Although hunting is the most important cause of these declines, logging also appears to be having a detrimental effect. In logged forest group densities of chimpanzee, red-capped mangabey, mona monkey and red-eared monkey decreased between the two survey years, whilst remaining constant or increasing in unlogged forest. The frequency of associations of guenon species did not differ between logged and unlogged study sites, but encounters of associations of all four guenon species were only found in unlogged forest. We strongly recommend enforcement of anti-poaching activities inside the Korup National Park, and establishment of wildlife management in the Support Zone, as only a combined strategy can successfully guarantee the persistence of the wildlife of the region.

AbstractThe extra-solar planet WASP-1b, discovered by SuperWASP consortium in 2006, was observed through R filter using the 1-meter telescope with CCD camera at Yunnan Observatory on November 11, 2006. The systematic errors in photometric data were reduced by means of Tamuz et al. (2005) and Collier Cameron et al. (2006)'s algorithms. In order to estimate the parameters of the system, the MCMC (Markov Chain Monte Carlo) analysis is applied to fit the observed light curve. The following parameters of the system are derived: Rp=1.44RJ, Mp=0.88MJ, R*=1.52R⊙, a=0.0396AU. The new parameters of the planet imply its low density, which agrees to the previous results.

Abstract:

Research Highlights: A transparent approach to developing a forest reference emissions level (FREL) adjusted to future local developments in Southern Cameroon is demonstrated. Background and Objectives: Countries with low historical deforestation can adjust their forest reference (emission) level (FREL/FRL) upwards for REDD+ to account for likely future developments. Many countries, however, find it difficult to establish a credible adjusted reference level. This article demonstrates the establishment of a FREL for southern Cameroon adjusted to societal megatrends of strong population—and economic growth combined with rapid urbanization. It demonstrates what can be done with available information and data, but most importantly outlines pathways to further improve the quality of future FREL/FRL’s in light of possibly accessing performance-based payments. Materials and Methods: The virtual FREL encompasses three main elements: Remotely sensed activity data; emission factors derived from the national forest inventory; and the adjustment of the reference level using a land use model of the agriculture sector. Sensitivity analysis is performed on all three elements using Monte Carlo methods. Results: Deforestation during the virtual reference period 2000–2015 is dominated by non-industrial agriculture (comprising both smallholders and local elites) and increases over time. The land use model projections are consistent with this trend, resulting in emissions that are on average 47% higher during the virtual performance period 2020–2030 than during the reference period 2000–2015. Monte Carlo analysis points to the adjustment term as the main driver of uncertainty in the FREL calculation. Conclusions: The available data is suitable for constructing a FREL for periodic reporting to the UNFCCC. Enhanced coherence of input data notably for activity data and adjustment is needed to apply for a performance-based payment scheme. Expanding the accounting framework to include forest degradation and forest gain are further priorities requiring future research.

Abstract:

Cross River gorillas are the least numerous of the African ape taxa. Since their rediscovery, several organisations have sought to conserve these critically endangered apes, resulting in a “crisis conservation narrative” focused on the threats posed by local human activities. However, landscapes are not just ecological, they are also social, shaped by political and economic processes. This study examines the interconnections between humans and gorillas by approaching the Mone-Oku forest as a combination of ecological, social, and political systems. Through a combined use of botanical surveys, analyses of nesting sites, participant observation, and semistructured interviews, we obtained nuanced ecological and ethnographic insights into the human–gorilla interface. The results illustrate a history of alterations within the Mone-Oku forest, some of which are human-induced. These alterations have had both positive and negative outcomes for the gorillas and continue to the present day, where political history has shaped limited livelihood alternatives, increasing the reliance on a forest that has remained a constant in the more recent history of “developmental” neglect and isolation. However, this situation is not static, with future alterations to the forest also subject to regional and international political and economic influences, such as the increased worldwide demand for cacao.

ABSTRACT During a large serosurvey of wild-caught primates from Cameroon, we found 2 mona monkeys (Cercopithecus mona) out of 8 and 47 mustached monkeys (Cercopithecus cephus) out of 302 with human immunodeficiency virus (HIV)-simian immunodeficiency virus (SIV) cross-reactive antibodies. In this report, we describe the full-length genome sequences of two novel SIVs, designated SIVmon-99CMCML1 and SIVmus-01CM1085, isolated from one mona (CML1) and one mustached (1085) monkey, respectively. Interestingly, these viruses displayed the same genetic organization (i.e., presence of a vpu homologue) as members of the SIVcpz-HIV type 1 lineage and SIVgsn isolated from greater spot-nosed monkeys (Cercopithecus nictitans). Phylogenetic analyses of SIVmon and SIVmus revealed that these viruses were genetically distinct from other known primate lentiviruses but were more closely related to SIVgsn all across their genomes, thus forming a monophyletic lineage within the primate lentivirus family, which we designated the SIVgsn lineage. Interestingly, mona, mustached, and greater spot-nosed monkeys are phylogenetically related species belonging to three different groups of the genus Cercopithecus, the C. mona, C. cephus, and Cercopithecus mitis groups, respectively. The presence of new viruses closely related to SIVgsn in two other species reinforces the hypothesis that a recombination event between ancestral SIVs from the family Cercopithecinae is the origin of the present SIVcpz that is widespread among the chimpanzee population.

Abstract:

An adult (presumably female) Herpele squalostoma was found attending 16 young in Cameroon. Four young that were preserved one day after collection have multicusped teeth and skin-like material in their gut. The adult and remaining young were maintained in captivity without provision of food for one month. During this period the young gained more than 10% in mass. Twenty-nine days after collection one additional young was preserved, this has adult-like dentition. We conclude that H. squalostoma resembles the oviparous caecilians Boulengerula taitanus and Siphonops annulatus in having young that receive extended parental care and that remove and eat the stratum corneum of maternal skin using specialized deciduous teeth. This discovery matches a prediction that maternal dermatophagy is widespread (and homologous) among teresomatan caecilians.

Abstract:

SUMMARYWe studied the seasonal fluctuation of norovirus and other enteric viruses in Cameroon. Two hundred participants aged between 1 and 69 years were prospectively followed up. Each participant provided monthly faecal samples over a 12-month period. A total of 2484 samples were tested using multiplex real-time PCR assay for the detection of norovirus, rotavirus and enterovirus. The effect of weather variables and risk factors were analysed by Pearson correlation and bivariate analysis. Overall, enterovirus was the most commonly detected virus (21·6% of specimens), followed by norovirus (3·9%) and rotavirus (0·4%). Norovirus and enterovirus were detected throughout the year with a peak of norovirus detection at the beginning of the rainy season and a significant alternation of circulation of norovirus genogroups from one month to the next. Age <5 years and consumption of tap water were risk factors for norovirus infection. Better understanding of factors influencing transmission and seasonality may provide insights into the relationship between physical environment and risk of infection for these viruses.

Abstract:

BackgroundThe incidence of sports-related sudden cardiac arrest (SrSCA) in sub-Saharan Africa is unknown.ObjectiveTo determine the incidence of sudden cardiac arrest (SCA) in non-competitive athletes in an urban population of Cameroon, a country in sub-Saharan Africa.MethodsTwo study populations in Cameroon were used. A 12-month, multisource surveillance system of 86 189 inhabitants over 12 years old recorded all deaths in two administrative districts of Douala City. All fields of sports, emergency medical service, local medical examiners and district hospital mortuaries were surveyed. Two blinded cardiologists used a verbal autopsy protocol to determine the cause of death. SCA was identified for all deaths occurring within 1 hour of onset of symptoms. A cross-sectional study was conducted among 793 persons in Yaoundé City, which is the second study population aimed at determining the proportion of people who are physically active.ResultsThe mean age in the cross-sectional study was 27.3±10.7, with more men (56.2%). The cross-sectional study showed that 69.0% (95% CI 65.8 to 72.2) of the population could be considered to have at least 3 hours of physical activity per week. The surveillance found that among 288 all-cause deaths, 27 (9.4%) were due to SCA. One SrSCA was registered in a 35-year-old woman while running. Merging both sources revealed an SrSCA incidence of 1.7 (95% CI 0.2 to 12.0) cases per 100 000 athletes per year.ConclusionThis pioneer study reports the incidence estimates of SrSCA in a sub-Saharan African general population and should be regarded as a first step to a big problem.
