Butterfly count on different habitats in international institute of tropical agriculture (IITA), Ibadan-Nigeria
(2022) Abideen A.A.; Oluwadara E.O.; Gabriel O.Y.; Adewale, A.
Butterflies are considered as good ecological indicators for other invertebrate and as surrogate representatives of environmental quality changes. Their occurrence and diversity in populations contribute to thriving ecosystems and can indicate the state of an ecosystem’s health. Though, there is high increase in habitat fragmentation of most protected area. However, information on butterfly species abundance, richness on different habitat is limited in the study area. The study assessed the diversity and abundance butterfly species in relation to its environmental factors. Sampling was done quantitatively using three complementary methods, line transect (walk-and-counts), hand nets, and fruit bait traps in June and July 2018. Data was analysed using descriptive statistics, diversity indices and Pearson’s correlation. A total of 646 individual representing 40 butterfly species belonging to 5 families in the order Lepidoptera were recorded across the three different habitats. Members of Nymphalidae family occurred most and accounted for 57.5% species and 63.3% total number of individual species with Acrsea serena been the most dominant across the habitats. Forest habitat had the highest species composition (n = 316). Generally, species abundance (31.0%), richness (33.7%) and family composition (33.7%) respectively, were recorded more through visual count method, while mean species abundance (26.1%) encountered higher with hand-net method. There was no significant relationship between the environmental factors and the total number of individuals or species richness. But rainfall was found to be positively correlated with the species diversity and abundance. Hence, understanding the factors affecting butterfly species diversity and abundance in IITA is very important for conservation purposes.
Feeding ecology of primates in Pandam wildlife park, Plateau State, Nigeria.
(2018) Abideen A.A.; Gabriel O.Y.; David E.
Primates are ecologically flexible and generalist feeders yet selective in choice of diet. Insufficient information on the plants consumed by primates hinders appropriate and deliberate conservation measures. I therefore seek to identify the plants species, dominant part consumed in Pandam Wildlife Park (PWLP). Direct observation method was adopted along 2km line transect to record food plants species and part consumed by primates for a period of 6 months. Proximate composition of food plants were determined using standard procedures. Data were analyzed using descriptive statistic and ANOVA at (p<0.01). Feeding sites were identified along riparian strata, savanna woodland and the swampy strata and four primates species belonging to one family (Cercopithecidae) were encountered, which include Cercopithecus mona, Erythrocebus patas, Papio anubis and, Chlorocebus tantalus, all primates were observed to feed in group. Seventeen food plants beonging to 14 families, one grass species (Andropogon gayanus), four invertebrates (Lumbrucis terrestris, Eurymerodesmus spp and Chinocectes opilio) and two crop plants (Zea mays and Sorghum vulgare) were identified. Plant parts consumed by primates include fruit, (75%) and leaves (25%). Among the food plant species, the highest crude proteins (11.86±0.07a), fats/oil (13.57±0.06a), ash (10.67±0.03a), moisture (13.63±0.07a), and crude fiber (27.85±0.48a) where obtained in Piliostigma thonningii, Rafia sundanica, Piliostigma thonningii, Stryhtinos spinose, and Tamarindus indica. Primates in the study area fed on variety of food items, predominantly on fruits irrespective of the season. Their frugivorous tendency has far ranching ecological implication with attendant effect on seed dispersal, seed treatment, seed predation, food predation, food competition, food provision, food scarcity among other sympatric animals that have fruits constituting a portion of their diet.
The pattern of local utilization and trade in wildlife /trophies in Saki West Local government area, Oyo State, Nigeria
(2021) Munir K.A.W; Abideen A.A.; Afusat A.A.; Isilamiyat A.L.
Wildlife species and trophies are of valuable use to humanity. These values include aesthetic, education, medicinal purpose, recreation, and as foreign exchange earner. Legitimate hunters and poachers alike are the main source of supply of wildlife species and trophies whilst vendors market them. This study is purposed to indicate the pattern of utilization of wildlife species in the study area. Fifteen sampled communities were surveyed in the study area. A hundred respondents were served with a copy of each of the questionnaires. The questionnaire sought information on the following variables namely, socio-economic characteristics of the respondents, source, and types of the species, and commercial dynamics of the trade. The Data collected were analyzed applying statistical tests including the t-test to determine the frequency distribution on the benefit-cost ratio and profitability index. The result revealed that the economic returns on both the wildlife species and trophies trade are profitable with a BCR (Benefit-cost ratio) of 5.00% (P = ≤ 0.05) and 2.92% respectively. This fact shows that wildlife species and trophies contribute significantly to the economics of the area. Conservation education and awareness should be encouraged against poaching and wild-scale domestication practices should be engaged in to reduce or even eliminate poaching activities on the wildlife species concerned. These measures should adequately supplement the animal protein level of traditional livestock and enhance sustainable food security globally.
