Item Preliminary Assessment of Fauna Species Diversity in Ipinu Igede Community Range Forest in Oju Local Government of Benue State, Nigeria(2018) Yager, G.O.; Alarape, A.A.; Onuwa, O.A.Background and Objectives: Appraisal of fauna species which form an integral part of range ecology, in rangeland based protected areas is necessary before any meaningful conservation work can commence. This study was aimed at assessing the composition of fauna species in the community forest. Methodology: Animal species were enumerated through direct on-site using four transects line of 2.0 km by 10 m broad distributed randomly, field observation and indirect indices. Data were analyzed using descriptive statistics (table, figures and plates). Results: Fifty-six species of wild animals from 40 families were observed in the study area. There were 21 species of mammals from 15 families, 6 species of reptiles from 6 families and 29 species of birds from 19 families. A total of 1,419 sightings were recorded. The most abundant animal species found in the area were Epixerus ebii, Eidolon helvum, Chlorocebus tantalus, Papio anubis, Philothemus irregularis, Musophaga violacea, Numidia meleagris and Francolinus bicalcaratus. The status of most mammals was Low risk-conservation dependent as applicable to reptiles. All the birds are known to breed in the reserve. Transect C had the highest diversity index (0.0130) and transect A had the lowest animal diversity index (0.0061) but with the highest species count of thirty six (36) and individual animal species sighted (454). Conclusions: The community forest support unique fauna species making it significant in terms of conservation and scientific interest and has to be protected through conservation awareness and community participation to conserve the current state and enhanced its range productivity.Item Evaluation of Range Condition and Trend of Ikwe Forest Reserve Igbor, Gwer-East Local Government Area of Benue State, Nigeria(2017) Yager G.O; Alarape, A.A.; Bunza, M.SPublic concern over biological resources assessment has grown over the decade due to a decline in resources through habitat fragmentation. The study was designed to evaluate the range condition and trend of Ikwe Forest Reserve in Gwer-East local government area of Benue State, Nigeria. Assessment of herbaceous cover and composition, woody plant/shrubs density and plant vigor were carried out in randomly selected sample plots. Litter cover was determined by step point transect method, while erosion and its extent were assessed by presence and degree of gullies. Data collected was analyzed using descriptive statistics and analysis of variance (ANOVA). Results obtained showed that the herbaceous cover composed of perennials (39%) and annuals (61%).Item The distribution and abundance of baboons (Papio Anubis) in Sambisa game reserve(2015) Modu, M.; Alarape, A.A.; Omifolaji, J.K.; Burabe, B.I.Base line information on animal population distribution and abundance is crucial to planning and implementation of effective management strategies for the conservation of species. There is paucity of information on the distribution and abundance of papio anubis in Sambisa game reserve. Therefore, this study was carried out to obtain information on estimate, population structure and abundance of the species, as well as habitat disturbances. The line transect sampling method was used for the enumeration. The data obtained was analyzed using the software package DISTANCE 6.0 to determine population density estimate. The result indicated that Baboon population was concentrated in three ranges of the Reserve a Range has suffered habitat disturbances resulting into insignificant number of primates. The mean encounter rates (MERs) for the species was 1.85km-1. Baboon had the estimated density of about 12km-2. There was a significant difference in the pattern of the species densities for morning and evening counts. The mean encounter rate for Baboon were 1.15 km-1 (n=110) and 0.71 km-1 (n= 68) individual animals for morning and evening sightings respectively. The relative density for the primate species across the four ranges in the reserve revealed that Baboon was not recorded in Balda range and only 2 individuals sighted in Jeltere. Kwada and yuwe range have the highest abundance of 119 and 57 individuals sighted respectively. The population structure shows declining trend as number of juveniles was relatively lower than adult population. However, the relatively higher percentage of female adults may result in population growth, if majority of them are within the breeding age. The highest numbers of primate species were found in the centre of the reserve (Kwada and Yuwe) where habitat disturbances were controlled.Item Relative density and distribution of tantalus monkey (Cercopithecus tantalus) in the four ranges of Sambisa game reserve(2015) Modu, M.; Alarape, A.A.; Omifolaji, J.K.; Burabe B.I.Tantalus monkey (Cercopithecus tantalus) was reported as widely abundant primate species in Sambisa Game Reserve. In order to provide information on the density of Tantalus monkey, this research was undertaken to study the abundance and distribution of the species in the Reserve. The line transects method of estimating animal population was used for the enumeration. An analysis of data was conducted using the software package DISTANCE 6.0 to determine population density estimate. Kwada, Yuwe, Jeltere and Balda are the four ranges within the reserve. Considering the number of species sighted, Tantalus monkey is widespread throughout the reserve where it was sighted in all the 4 ranges with the highest density of 10.84 km-2 (n=80) in Yuwe range. In Jeltere ecological habitat for the species survival is under threats. Habitat loss and habitat degradation in the area are principally due to illegal logging, forest fires and forest clearance for agriculture harbored very few individual of the species. The mean encounter rates (MERs) for the species 1.58km-1 with density estimate of about 11km-2. There was a significant difference in the pattern of the species densities for morning and evening count indicating less activity in the evening with mean encounter rate of 0.54 km-1 (n=85) and 0.43 km-1 (n= 67) individual animals for morning and evening sightings respectively. The relative density for the species across the four ranges in the reserve revealed that Tantalus monkey was present in all the four ranges of the game reserve. A total of only 21 Tantalus monkey were sighted in the Balda range, this calls for close monitoring and control of its population particularly within the range.Item Wildlife Diversity, Habitats and Dynamics, The Tripod For Sustainable Ecotourism Management in Nigeria(Ibadan University Press, 2021) Alarape, A.A.
