Seasonal variation in plants consumption pattern by foraging Olive Baboons (Papio anubis. Lesson, 1827) inside Kainji Lake National Park,

This study which lasted for eight (8) months in 2011, covering the period of dry and wet seasons examined seasonal plant species consumed by foraging Olive baboon (Papio anubis) inside Kainji Lake National Park, Nigeria. Data were collected in the morning between 8.00am - 12.00pm and in the evening between 2.00pm - 6:00pm. Plant species and their parts eaten were monitored and identified through direct observation and faecal analysis. It was observed that seven plants species ((Andropogon gayanus, Strychnos spinosa, Nuclear latifiora, Vitelaria paradoxa, Ficus sycomorus, Annona senegalensis and Tamarindus indica ) were consumed in the wet season with 303 feeding events while ten plants species (Detarium macrocarpum, Gardenia sotoemsis, Parkia biglobosa, Piliostigma thonningii, Pterocarpus erinaceus , Prosopis africana, Ficus sycomorus, Xamenia americana, Annona senegalensis and Vitex doniana) were consumed during the dry season with 315 feeding events. The feeding pattern shows that plants with higher nutritional quality were often consumed. Seasonal variation showed slight disparity in the nutrient composition of the identified plants. It was concluded that seasonal variations do affect the plants consumption pattern of foraging Olive baboon and that exsitu conservation of these plants is imperative for sustainable captive management of Olive baboon. © JASE

Population status of olive baboon Papio anubis (lesson, 1827) in Kainji lake national park, Nigeria

The study assessed the population status of Olive Baboon Papio anubis in Kainji Lake National Park, in both sectors of the park. Direct count was carried out on the line transect where activities of Olive Baboon Papio anubis was observed during reconnaissance survey. It involves counting of individual or group of individual species sighted. While the indirect method involves gathering information on current locations for primate through consultation with experience Park Rangers, hunters, farmers and community leaders, counting of animal index such as feacal droppings, foot prints, calls, and feeding remnants, within each transect. These were related to relative abundance/distribution of Primates in a particular area at a particular time. Data was collected from November, 2017-August, 2019. Data was analyzed using distance software. Student t-test was used to compare between wet and dry seasons population. The results were presented in tables. The overall Population estimation revealed Papio anubis has the highest mean abundance (19 ± 0), population density (0.042 ± 0.000) and relative abundance of (6 ± 0) at Oli range and the species was not observed in the two ranges of Zugurma sector of the park. Individuals and troops recorded during the dry seasons exceeded those of the wet seasons in all the sectors during the study. The population structures (age and sex) adult female Olive Baboon has the highest mean of individual in all seasons with (140 ± 41) the least in the troop been the Sub-adult male with (32 ±6). The Olive baboons were observed to be social and a very popular attraction for park staff that resident in the Oli camp, visitors and researches alike.

Selected indigenous wild fruits influence on feeding behaviour of captive olive baboons (Papio anubis. Lesson, 1827))

Feeding behaviour of captive male olive baboons was studied in a 200 feeding trial using five selected indigenous fruits: Strychnos spinosa (SS), Nuclear latifolia (NL), Piliostigma thonningii (PT), Detarium macrocarpum (DM) and Adansonia digitata (AD), categorized into large, medium and small sizes with a view to foster this animal ex-situ conservation. The fruits were harvested fresh and served on the floor of the cages in-between morning and afternoon routine feeding. Data were collected on fruit choice to determine fruits preference; time spent to remove or break the fruits pericarp; and the position of the animal while eating. This study shows that fruits preference was significantly (p < 0.05) influenced. It followed the order: DM>NL>PT>SS>AD. Experimental Olive baboons picked small fruits ahead of others irrespective of their nutritional quality. Time spent to remove or break the fruits pericarp were significantly (p < 0.05) influenced. On eighty-nine occasions, captive Olive baboons preferred hanging on the cages walls while eaten. For sustainable conservation of this fauna species, more research on its feeding behaviour with respect to these fruits shape, weight and colour is encouraged.  Key Words: Olive baboons, Conservation, Feeding behaviour, Wild fruit

Conservation Status and Habitat Preferences of Common Warthog ( Phacochoerus Africanus ) in Old Oyo National Park, Nigeria

This study assessed the conservation status and habitat preference of Common warthog in Old Oyo National Park, Nigeria using direct sighting and line transect method. The abundance estimate and encounter rate of common Warthog in the study area from 2018-2019 showed that year 2018 recorded 213 individuals at an encounter rate of 0.38/km while year 2019 recorded 184 individuals at an encounter rate of 0.32/km while the mean abundance estimate of common Warthog are 4.65\ub10.64 and 1.71\ub10.48 which represents 156 and 58 individuals at encounter rate of 0.55/km and 0.20/km in the wet season and dry season of year 2018 compared to year 2019 with average abundance estimate value of 4.00\ub10.85 and 1.41\ub10.61 which represents 135 and 48 individuals at an encounter rate of 0.47/km and 0.17/km for wet and dry season respectively. The mean age structure and sex ratio of the observed warthog population during dry and wet seasons revealed that juveniles had highest mean of age structures among the populations observed across the seasons. The habitat preference of common warthog revealed that they are mostly found in mixed woodland and open savanna with 112 observation and the lowest was recorded in the outcrop vegetation and open savanna with 21 individuals.in the wet season. During the dry season, mixed woodland/open savanna and Riparian grassland had the highest sightings of 45 and 33 individuals each. The outcrop vegetation/open savanna had the lowest observation of 1 individuals only. The study also recommends that more aspect of the ecology of the animal should be studied in details and emphasis should be placed on the habitat requirements

Global Burden of Sickle Cell Anaemia in Children under Five, 2010-2050: Modelling Based on Demographics, Excess Mortality, and Interventions

The global burden of sickle cell anaemia (SCA) is set to rise as a consequence of improved survival in high-prevalence low- and middle-income countries and population migration to higher-income countries. The host of quantitative evidence documenting these changes has not been assembled at the global level. The purpose of this study is to estimate trends in the future number of newborns with SCA and the number of lives that could be saved in under-five children with SCA by the implementation of different levels of health interventions.First, we calculated projected numbers of newborns with SCA for each 5-y interval between 2010 and 2050 by combining estimates of national SCA frequencies with projected demographic data. We then accounted for under-five mortality (U5m) projections and tested different levels of excess mortality for children with SCA, reflecting the benefits of implementing specific health interventions for under-five patients in 2015, to assess the number of lives that could be saved with appropriate health care services. The estimated number of newborns with SCA globally will increase from 305,800 (confidence interval [CI]: 238,400-398,800) in 2010 to 404,200 (CI: 242,500-657,600) in 2050. It is likely that Nigeria (2010: 91,000 newborns with SCA [CI: 77,900-106,100]; 2050: 140,800 [CI: 95,500-200,600]) and the Democratic Republic of the Congo (2010: 39,700 [CI: 32,600-48,800]; 2050: 44,700 [CI: 27,100-70,500]) will remain the countries most in need of policies for the prevention and management of SCA. We predict a decrease in the annual number of newborns with SCA in India (2010: 44,400 [CI: 33,700-59,100]; 2050: 33,900 [CI: 15,900-64,700]). The implementation of basic health interventions (e.g., prenatal diagnosis, penicillin prophylaxis, and vaccination) for SCA in 2015, leading to significant reductions in excess mortality among under-five children with SCA, could, by 2050, prolong the lives of 5,302,900 [CI: 3,174,800-6,699,100] newborns with SCA. Similarly, large-scale universal screening could save the lives of up to 9,806,000 (CI: 6,745,800-14,232,700) newborns with SCA globally, 85% (CI: 81%-88%) of whom will be born in sub-Saharan Africa. The study findings are limited by the uncertainty in the estimates and the assumptions around mortality reductions associated with interventions.Our quantitative approach confirms that the global burden of SCA is increasing, and highlights the need to develop specific national policies for appropriate public health planning, particularly in low- and middle-income countries. Further empirical collaborative epidemiological studies are vital to assess current and future health care needs, especially in Nigeria, the Democratic Republic of the Congo, and India

Biodiversity, traditional medicine and public health: where do they meet?

Given the increased use of traditional medicines, possibilities that would ensure its successful integration into a public health framework should be explored. This paper discusses some of the links between biodiversity and traditional medicine, and addresses their implications to public health. We explore the importance of biodiversity and ecosystem services to global and human health, the risks which human impacts on ecosystems and biodiversity present to human health and welfare

Disappearance and appearance of an indigestible marker in feces from growing pigs as affected by previous- and current-diet composition

Abstract Background Indigestible markers are commonly utilized in digestion studies, but the complete disappearance or maximum appearance of a marker in feces can be affected by diet composition, feed intake, or an animal’s BW. The objectives of this study were to determine the impact of previous (Phase 1, P1) and current- (Phase 2, P2) diet composition on marker disappearance (Cr) and appearance (Ti) in pigs fed 3 diets differing in NDF content. Results When pigs were maintained on the 25.1, 72.5, and 125.0 g/kg NDF diets, it took 5.1, 4.1, and 2.5 d, respectively, for Cr levels to decrease below the limit of quantitation; or 4.6, 3.7, or 2.8 d, respectively, for Ti to be maximized. These effects were not, however, independent of the previous diet as indicated by the interaction between P1 and P2 diets on fecal marker concentrations (P < 0.01). When dietary NDF increased from P1 to P2, it took less time for fecal Cr to decrease or fecal Ti to be maximized (an average of 2.5 d), than if NDF decreased from P1 to P2 where it took longer for fecal Cr to decrease or fecal Ti to be maximized (an average of 3.4 d). Conclusions Because of the wide range in excretion times reported in the literature and improved laboratory methods for elemental detection, the data suggests that caution must be taken in considering dietary fiber concentrations of the past and currently fed diets so that no previous dietary marker addition remains in the digestive tract or feces such that a small amount of maker is present to confound subsequent experimental results, and that marker concentration have stabilized when these samples are collected
