International Journal of Primatology Research ABSTRACT Menchum landscape, has recently becomes a vital research ground for the conservation of a variety of wildlife and primate species, most especially the endangered Nigeria-Cameroon chimpanzees (Pan troglodytes ellioti). Despite conservation eff orts, drills have been extinct in most of their natural habitats, with revealing presence of olive baboons due to overhunting and habitats loss. As such, this study was undertaken in the Menchum Landscape; Case study of the Kimbi-Fungom National Park (K-FNP) and Kom-Wum Forest Reserve (K-WFR), aimed to practically investigate the status of drills and baboons in order to contribute vital information for their conservation. Primary data were obtained through recces walk, whereby direct and indirect observations of bio-indicators and human signs were recorded and analyzed manually to obtain their encounter rate. From the results, 13 and 289 drills and olive baboons individuals were directly observed which gave a mean encountered rate of 0.10 signs/km and 2.21 signs/km respectively. Up to 38 voices of olive baboons were heard and and 16 carcass observed which gave an encountered rate of 0.33 signs/km and 0.17 signs/km respectively. Distribution analysis of these primates shows that 100% of drills and 27% of olive baboons were concentrated in the Black Bush Areas of Window. Anthropogenic activity gave an average encountered rate of 0.32 signs/km mean while all signs associated with hunting, registered the highest encountered rate of 0.68 signs/km. Thus, upgrading data on the abundance and distribution of drills and baboons, identifying areas of intense anthropogenic activities through eff ective conservation methods will greatly help to identify hotspots and ensure better protection for these species. Also, it is vital to undertake regular educational conservation plans to promote all stakeholders on the necessity to conserve the remaining species, especially the few drills population.

Councils are facing a formidable task to establish sustained and sustainable economic growth through increased performamce and productivity as the necessary basis for reducing poverty. An informed approach is to have a strategy to face the future challenges and missions of the council. The strategic instrument is the Council Development Plan (CDP) which is a document that aims to bring public service closer to the population by a total commitment of the council towards the population it serves. With the decentralization process, the administrative and institutional environment of council management, its human, material and financial resources will be called upon to increasingly contribute. Our space here is Benakuma Council which was created in 1993 by Decree No. 93/321 of 25 November 1993 relating to the creation of Urban and Rural Councils in Cameroon. The council area corresponds to the Menchum Valley Sub-Division, Menchum Division in the North-West Region of Cameroon. The council went operational in 1996 covering a surface area of 1 050 sq. km and a total population of 50 384 inhabitants as per the 2005 General Population and Housing Census. There are two main clans in the municipality: the Beba-Befang and the Esimbi clans.

They are widely used as a nonhuman primate model for biomedical studies, and the Southwest National Primate Research Center (SNPRC) at Texas Biomedical Research Institute has maintained a large captive baboon colony for more than 50 yr. Unlike other model organisms, however, the genomic resources for baboons are severely lacking. This has hindered the progress of studies using baboons as a model for basic biology or human disease. Here, we describe a data set of 100 high-coverage whole-genome sequences obtained from the mixed colony of olive (P. anubis) and yellow (P. cynocephalus) baboons housed at the SNPRC.

  • The Social Daily Activity Correlation of Olive Baboon (Papio Anubis) in Gashaka-Gumti National Park, Nigeria
    Annals of Ecology and Environmental Science Volume 2, Issue 1, 2018, PP 23-28 The Social Daily Activity Correlation of Olive Baboon (Papio Anubis) in Gashaka-Gumti National Park, Nigeria Melle Ekane Maurice1*, Lameed G.A1 1Department of Environmental Science, Faculty of Science, University of Buea, Cameroon 1Department of Wildlife and Fisheries Management, Faculty of Agriculture and Forestry, University of Ibadan, Nigeria *Corresponding Author: Melle Ekane Maurice, Department of Environmental Science, Faculty of Science, University of Buea, Cameroon. ABSTRACT Baboons range throughout sub-Saharan Africa, across a multitude of habitat types making them the most widespread African primate genus and perhaps coincidentally, are one of the best studied primates. In recent times, the rapid expansion of human population, the spread of agriculture, and the resulting destruction of natural habitats has drastically increased in sub-saharan Africa. Thus, the consequences of this close association between wildlife and humans are absolutely relevant to conservation and management strategies. The objective of this study was to determine the daily correlation of social behavior of the Olive baboon in the national park ecosystem. The study was undertaken for one year in Gashaka-Gumti National Park, Taraba State, Nigeria. A single animal group habituated for some years by a previous research team was constantly followed for a focal and scan data collection. The daily and monthly data collected on checksheets was statistically analysed using the Chi-square and correlation statistical models. The Olive baboon daily movement activity or, positively and significantly correlated to feeding r2 = 0.82, and vocal r2 = 0.80 at (P<0.05) respectively.

  • The Sex Lives of Female Olive Baboons (Papio Anubis)
    Competition, coercion, and choice: The sex lives of female olive baboons (Papio anubis) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jessica Terese Walz Graduate Program in Anthropology The Ohio State University 2016 Dissertation Committee: Dawn M. Kitchen, Chair Douglas E. Crews W. Scott McGraw Copyrighted by Jessica Walz 2016 Abstract Since Darwin first described his theory of sexual selection, evolutionary biologists have used this framework to understand the potential for morphological, physiological, and behavioral traits to evolve within each sex. Recently, researchers have revealed important nuances in effects of sexual coercion, intersexual conflict, and sex role reversals. Among our closest relatives living in complex societies in which individuals interact outside of just the context of mating, the sexual and social lives of individuals are tightly intertwined. An important challenge to biological anthropologists is demonstrating whether female opportunities for mate choice are overridden by male- male competitive and male-female coercive strategies that dominate multi-male, multi- female societies. In this dissertation, I explore interactions between these various mechanisms of competition, coercion, and choice acting on the lives of female olive baboons to determine how they may influence expression of female behavioral and vocal signals, copulatory success with specific males, and the role of female competition in influencing mating patterns. I found females solicit specific males around the time of ovulation. Although what makes some males more preferred is less clear, there is evidence females choose males who might be better future protectors – males who will have long group tenures and are currently ascending the hierarchy.

These regions of Cameroon have been restive since 2016 in what is popularly referred to as the Anglophone crisis. The crisis has been transformed to a separatist movement, with some Anglophones clamoring for an independent No-So, re-baptized as “Ambazonia”. The purpose of the study is to illuminate the geopolitical perspective of the conflict which has been evaded by many scholars. Most scholarly write-ups have rather focused on the causes, course, consequences and international interventions in the crisis, with little attention to the geopolitical undertones. In terms of methodology, the paper makes use of qualitative data analysis. Unlike previous research works that link the unfolding of the crisis to Anglophone marginalization, historical and cultural difference, the findings from this paper reveals that the strategic location of No-So, the presence of resources, demographic considerations and other geopolitical parameters are proving to be responsible for the heightening of the Anglophone crisis in Cameroon and in favour of the quest for an independent Ambazonia.

Abstract: Baboons are the type of monkey that are found in African forests and the Arabians. There are five species of baboons worldwide which are distributed in different habitats such as tropical rainforests, savannas, open woodlands and semi-arid areas. A close observation made on baboons at the Yankari Game Reserve(YGR), showed that they feed on various foods which are the reason they are known as pests as well as they are scavengers on elephant's dung. Apart from poaching activity by humans, baboons at YGR are also threatened by loss of habitat due to regular predatory activity by a lion (Pathera leo) in the reserve on the baboons. Out of the five species, only one species (Papio anubis) are found in the large population at the Yankari Game Reserve. This increase in the population of the olive baboons at the YGR has become a source of concern to tourists and researchers who visit the reserve. Due to frequent visits by people to the reserve, the baboons has developed a high level of intellectualism as well as tricks to overcome the dominance by humans encroaching their habitat. Some of these behaviours are groupings, pretence, and acrobatics.

Hans H. de Iongh (Leiden University, Leo Foundation) MSc Luka L. Narisha (Kenya Wildlife Service) Lion (Panthera leo melanochaita) diet in relation to prey preference and density in Meru National Park, Kenya Mateo Bal s0185753 This research project was developed within a collaborative framework between the University of Antwerp, the Institute of Environmental Sciences of Leiden University, Kenya Wildlife Service, the Leo Foundation and the Born Free Foundation. Submitted to obtain the master’s degree in biology - specialisation Biodiversity, Conservation and Restoration. 2 ABSTRACT The African lion (Panthera leo) plays a key role in savannah ecosystems by directly and indirectly regulating trophic structure. Their foraging behavior has frequently been described as opportunistic, but often reveals a distinct preference for certain prey species that are energetically more profitable. This research project focussed on the population structure and diet of lions in Kenya’s Meru National Park. Data were collected from February until April 2019 and contribute to the PhD research of MSc Luka Narisha. A total of 28 lions were identified during fieldwork, indicating a lion density of 2.2 adult lions per 100 km2. Transect counts of potential prey species in the park revealed that Kirk’s dik-dik (Madoqua kirkii) had the highest relative abundance of all prey species (50.89%), while African buffalo (Syncerus caffer) contributed the most to the total prey biomass (33.94%).
