Short note on observation of breeding activities of the lander horseshoe bat (Rhinolophus Landeri- martin, 1837) within an urban area in southwest, Nigeria
(2022) Adeyanju, T. E.; Alarape. A.A
This study made observations on breeding activities of the Lander Horseshoe bat in southwest, Nigeria. Bats were captured using mist nets placed in the ground storey at the University of Ibadan, southwest, Nigeria. Forty-two per cent of total R. landeri (n=14) captured in March, 2017 and between February-August, 2019 were breeding either pregnant or with pups. Though distribution of the species is believed to range nationwide, the last report on breeding activity was about forty-six years ago and with a data deficient status; this observation is the first record for the breeding activities of R. landeri on the southwest range of
Impact of Anthropogenic Activities on Vegetation Cover and Mammalian Herbivores in Afi Mountain Wildlife Sanctuary, Cross River State, Nigeria
(2022) Yager, G.O.; Alarape, A.A.; Onaji, O.J.; Acha, S.
Despite the popular perception of protected areas, forest resources are still subject to many forms of anthropogenic activities such as logging, hunting and burning. This necessitates the study on the impact of anthropogenic activities on vegetation cover and mammalian herbivores in Afi mountain wildlife sanctuary. Four communities around the study area namely; Ebok, kakukob, Esekwe and Olum were selected based on proximity to the sanctuary. Data on socio-economic characteristic and anthropogenic activities of the communities were determined using questionnaire. A total of sixty (60) copies of questionnaire, 15 each were distributed to the four communities. Dynamics in vegetation cover for 1985, 2000 and 2021 was determined using landsat imagery. Data were analyzed using descriptive statistics, Normalized Difference Vegetation Index. The result revealed that, males (65.0%) were the dominant respondents. The study respondents were in the age bracket between 41-50 years (51.6%) and majority (51.7%) can at least read and write. The result also indicates a drastic decrease in the forest cover as from 1985-2021, owning to increase in activities such as settlement, logging and farming within the sanctuary. Major threats to the vegetation cover and mammalian herbivores survival were farming, logging and illegal hunting. Conservation of the remaining forest resources should be given top priority.
Diversity and Distribution of Anomalures and Squirrels in Oban Hills of Nigeria
(2022) James, K.O.; Emmanuel,T.I.; Abideen, A.A.; Saka,O.J.; Christian ,J.A.K.; Gautam, D.; Xiaofeng, L.
The Congolian tropical forest represents the epicenter of biodiversity conservation and squirrel diversity in the Western and Central African region of sub-Saharan Africa. The scientific knowledge gap of squirr el species diversity,distribution and ecology of the region is limited. We investigated anomalure and squirrel richness and diversity in different land-use types in the Oban region, Nigeria between January 2010 and April 2013 to update species baseline information on squirrels. In total we recorded 495 individuals of seven species and six genera representing, Anomaluridae and Sciuridae families, were detected in the Oban Hills Region. The Anomaluridae family accounted for one genus and one species (Anomalurus beecrofti),while the Sciuridae family is represented by the Xerini and Protoxerini tribes in five genera (Funisciurus, Heliosciurus, Xerus, Paraxerus, and Protexerus). Encounter rates with five different species revealed that the Protoxerini tribe (FunisciurusanerythrusandHeliosciurusrufobrachium)werethemostfrequentlydetectedacrossallthe land-use types in the region. The high diversity of squirrels detected in the region could be a reflection of its recognition as a biodiversity hotspot. Also,closed-canopy cover had the highest diversity index and evenness recorded than farm fallow. Studies on population monitor in ecology and conservation help species- and site-specific conservation strategies in the region. We conclude that closed-canopy forest has high conservation value, and that management should be initiated where possible to alleviate threats to its continued functioning and effort must be directed towards ascertaining the ecology and biology of squirrel species for effective conservation strategies.
Population abundance, density and diversity of antelope species in pandam wiildlife park, plateau state, Nigeria
(2022) Gabriel, Y. O.; Abideen, A. A.
Habitat loss and fragmentation are heating deep into conservation areas like Wildlife Parks and this has posed a serious threat to wildlife population abundance and diversity. The fluctuations in population of fauna species are dependent on the quality of the habitat. Therefore, the population abundance, density and diversity of antelope species were investigated. Line transects (2 km each) were laid 1km apart in: savannah woodland-SW (n=4), riparian forest -RF (n=3) and swamp land-SL (n=3). The line transect method was used to identify antelopes during wet (July-October) and dry (December-March) seasons (2017-2019). Simpson’s (D) and Shannon-Weiner (H’) indices were estimated for herbivores. Data were analysed using descriptive statistics and ANOVA at α0.05. Four Antelopes were identified and Kobus kob was most dominant. Antelope abundance and mean population density increased from SL (18, 2.3) to SW (80, 10) and were higher in dry (70, 8.8) than wet (56, 7.0) season. Antelopes, highest D (0.7) and H’ (1.6) were in SW, while least were in SL (D= 0.6, H’= 1.2). The savannah woodland favoured the antelopes and had influence on their abundance and diversity. Antelope species were almost not found in other habitats due to human activities within the park. The anthropogenic activities are fast entering into the core area of the park. Hence, the park management should take strategic measures to curb this fast-rising challenges.
People’s Perception about Plant-based Formulated Diets as a Non-chemical Method of Rodent Population Control in Nigeria
(2022) Badmus, H.A.; Alarape, A.A.
A total number of two hundred and thirty five (235) respondents responded to the self-structured (online Google form) questionnaires administered to them without being bias to sample their opinions on the performance of common rodent population control methods and their readiness to embrace plant-based formulated diets as a method of rodent population control in Nigeria. Statistical Package for Social Sciences (SPSS) was used to analyze the questionnaires. The results showed that rodent population should be controlled to reduce their damage to agricultural crops (97.4%), to reduce zoonotic diseases (94.9%), and for conservation reasons (82.6%) in Nigeria. It was also revealed that some of the common rodent population control methods were found to be humane, cost effective, acceptable, and effective but at different levels. The plant-based formulated diet as a method of population reduction would be humane (69.8%), acceptable (65.1%), and effective (68.5%) method. The plant-based formulated diet was viewed as a promising method and this indicated readiness to adopt the method as an alternative to the common methods of rodent population control.
