  • Assessment of tree species and their utilization in Kurfi local government
           area of Katsina State, Nigeria

    • Authors: N. Abdurrasheed , M.T. Okoh
      Abstract: The study was carried out in Kurfi Local Government Area of Katsina State, Nigeria. Situated in dry land region of the State. Data was collected with pre-tested questionnaires administered to 120 farmers randomly selected as sample for the entire population. Information was gathered on the demographic characteristics, utilization of the tress species; including the different parts used and their uses, benefits and challenges of tree species. Data collected were analyzed using a descriptive statistic. The results from the respondents indicated the uses of tree species, the different part used and their functions, 11% of the respondents uses the leaves of Adansonia digitata, and 12% uses the leaves of Acacia albida as animal feed, other uses include mulch, condiments and medicinal purposes. Also, 67% and 33% of the respondents use seeds for animal feed and food, respectively. Among the challenges faced by the farmers, 48% of the respondents indicated the occurrence of pest and diseases as well as urbanization as one of the factors endangering tree species in Kurfi Local Government Area. From the result obtained, it was discovered that most tree species found in the study area were used for food, medicine and animal feed. The most common trees found in the area includes Adansonia digitata, Parkia biglobosa, Tamarindus indica etc. It is recommended that committee which shall be saddle with the responsibility of conserving and managing tree species within the study area among other things should be constituted. There is also a need for further study in the future that will focus not only on composition but includes other parameters that will assess species richness, evenness, diversity and similarity. These will provide adequate information for conservation and management purpose.

  • Determination of leaf litter input, quality, and decomposition rates in
           young Nauclea diderrichii and Terminalia superba plantations in Nigeria

    • Authors: S.O. Olajuyigbe , M.O. Adebo
      Abstract: Using litter traps and a litterbag experiment, the input, decomposition rates and changes in chemical characteristics of leaf litter were evaluated in seven-year-old Nauclea diderrichii and Terminalia superba plantations in Nigeria. Four plots (25 m by 25 m) were laid in the Nauclea diderrichii plantation, while three (25 m by 25 m) were laid in the Terminalia superba plantation. One litter trap was placed in each plot, while 30 litterbags containing leaf litter of each species were randomly placed in each plantation for 80 days. Litter input per month, leaf litter weight loss, nitrogen, organic carbon, phosphorus, lignin, polyphenol contents, C:N and lignin: N ratios of the litter samples were determined. After four months, there was no significant difference in the monthly litter input to each plantation. However, monthly litter input was higher in Nauclea stand (549.21kg ha-1) than Terminalia (109.02 kg ha-1). After 80 days, 39.81% and 54.15% of leaf litter weight was remaining for Terminalia superba and Nauclea diderrichii, respectively. The single exponential decay constants were 0.0093 day-1 (Nauclea diderrichii) and 0.0096 day-1 (Terminalia superba). As decomposition progressed, nitrogen, phosphorus, organic carbon, lignin and polyphenols varied differently for the two species. Phosphorus and C: N ratio increased with time of decomposition for both species. However, the C: N ratio of Terminalia leaf litter had a sudden decrease after 80 days, suggesting mineralization of the leaf litter.

  • Seasonal variation, diversity and population dynamics of four species of
           monkey in Okomu National Park, Edo State, Nigeria

    • Authors: S.A. Ekaye, S.O. Ogoanah
      Pages: 1 - 10
      Abstract: The aim of this work is to ascertain the diversity, seasonality and dynamics of four monkey species in Okomu National Park, a lowland rainforest ecosystem of Edo State, Nigeria. It covers a land mass area of approximately 200km square, making it the smallest of the National Parks in Nigeria. Daily surveys of monkeys were carried out between 7:00am and 11:00am while evening surveys were between 03:00pm - 06:00pm for 8 months covering 4 months of wet season and 4 months of dry season. Each trail was traversed twice daily with an average walk speed of 1.0 km/hr. Sightings was aided with binoculars, digital camera and acoustic detection. Results showed that a total of 1391 monkeys were sighted, six hundred and sixty-two (662) in the wet season and seven hundred and twenty-nine (729) in the dry season. The results also show that the percentage abundance is Cercopithecus mona > C. erythrogaster > Cercocebus torquatus > Cercopithecus nictitans. The overall percent composition of the species showed that C. mona had the highest of 48.5%, followed by C. erythrogaster 27.12%, C. torquatus 18.85% and the least was C. nictitans 12.75%. This study confirms the prevalence of four (4) species of Monkey in Okomu National Park which are Cercopithecus mona, Cercopithecus erythrogaster, Cercopithecus nictitans and Cercocebus torquatus. Biological indices indicate that Cercopithecus erythrogaster is the most diverse and the richest species in Okomu while the least diverse species is Cercocebus torquatus. Cercopithecus nictitans is the most evenly distributed monkey species in Okomu National Park. We recommend continuous survey and monitoring of primate species in this area and encourage community-based conservation policies to protect the already threatened primates and habitat.

  • Incidence of infanticide among captive wildlife in some selected zoos in
           Nigeria

    • Authors: H.O. Jegede, B.N. Ogunro, A.B. Hanga, S.O. Oyerinde
      Pages: 11 - 17
      Abstract: This study aimed at revealing the cause of infanticide among zoo collections and proffer strategies to mitigate its occurrence. Three zoos in Nigeria were studied using empirical data from 20-year Veterinary retrospective records and circumstances surrounding the occurrence. A total of 17 infanticide cases were reported from three zoos in Nigeria; 8 from UNILORIN Zoo, seven from UI Zoo and two from Kano Zoo. A total of 55 infants were found to have died during the 17 infanticide events. The Nile Crocodile accounted for the highest number of individual infant deaths, while the side-striped jackal accounted for the highest frequency of infanticide events. The occurrence was highest in carnivores, and major offenders were of maternal origins, accounting for 59% of all infanticides. Exploitation was observed as the major motive, either sole or combined with other motives. This study assessed scenarios surrounding maternal infanticide in different animal species and predisposing factors peri-occurrence. We also proposed possible solutions, especially in developing nations’ zoo settings, where this occurrence is grossly under-reported and most often neglected. Correction of observed factors linked with infanticide led to the prevention of further occurrence of infanticide in the three zoos.

  • Effects of temperature and relative humidity on colonization of bees hives
           within Futa community

    • Authors: F.O. Oluwaseyi , M.A. Mustapha, I.G. Oluwaseyi
      Pages: 18 – - 18 –
      Abstract: The objective of this study was to determine the effects of temperature and relative humidity on colonization of honey bee hives within FUTA community. An initial reconnaissance survey was carried out prior to the commencement of the study; the coordinates of all the locations were taken and recorded with a GPS. Three different locations were used for this study, and three artificial beehives were constructed and placed at these three locations within the FUTA community. The study lasted for fifteen weeks. The climatic conditions of these three locations were measured each week, i.e. temperatures and relative humidity. Variations in these climatic factors were observed throughout the fifteen weeks of this study. The beehive located behind the Quarantine section of Prof. T.A Afolayan Wildlife Park) had the maximum temperature of 31.4 ⁰c and low relative humidity of 76.9%, while the beehive located at Animal Production and Health Teaching and Research Farm had a minimum temperature of 28.0⁰c and maximum relative humidity of 80.5% after fifteen weeks. At the 6th week, 8th and 9th week respectively the beehives were all noticed to have been colonized respectively. There was significant difference between the the mean of temperature of the three different locations. This study shows that the modern/artificial beehive under a good climatic condition and management is a sustainable way of high honey production, bees tends to thrive under relatively high temperature and relatively low humidity.

  • A comparative assessment of aspects of reproductive biology of two
           freshwater prawns, Macrobrachium felicinum (Holthuis, 1949) and Atya
           gabonensis (Giebel, 1875) in River Benue, Makurdi, Nigeria

    • Authors: C. Obetta, R.A. Obande, J.O. Cheikyula, S.G. Solomon
      Pages: 26 - 30
      Abstract: This work was designed to determine and compare sex ratio, fecundity, egg diameter and gonadosomatic index of M. felicinum and A. gabonensis in Lower River Benue from January to December 2016. A total of 295 M. felicinum were sampled with an overall sex ratio of 8.52:1(F:M). The highest sex ratio of female to male (12:1 F:M) was in August while the least was in September (5.00:1 F:M). About 2413 Atya gabonensis were collected with an overall sex ratio of 1:211. F:M Fecundity varied from 230 - 69,782 eggs in M. felicinum and 4,300 - 8,600eggs in A. gabonensis. Stronger correlation was observed between fecundity and total length (r=0.64 in M. felicinum and 0.87 in A. gabonensis). Mean egg diameter of A. gabonensis was 0.46 ± 0.0 mm and that of M. Felicinum was 0.44 ± 0.03. Macrobrachium felicinum showed higher Gonadosomatic Index (0.58 ± 0.041) than A. gabonensis (0.33 ± 0.009). Macrobrachium felicinum appeared to have more reproductive output than A. gabonensis. Both species, A. gabonensis and M. felicinum were recommended as good candidates for culture as their seeds are readily available in the Lower River Benue.

           within Ilorin metropolitan communities, Nigeria

    • Authors: K.R. Adebayo , I.K. Adesina , F. A. Adeniji
      Pages: 31 - 38
      Abstract: This study evaluated the quality of water samples collected from twenty-seven open wells located at nine selected fuel stations situated within three Ilorin metropolitan areas. Three stations each, in the three local government areas were randomly selected. Physiochemical parameters of samples and total petroleum hydrocarbon (TPHC) were analysed for any possible petroleum product leaking from the station’s underground storage tank into the nearby wells, using standard methods for the analysis. Physiochemical values of the samples analysed for Ilorin South fuel Stations (SFS), Ilorin East fuel stations (EFS) and Ilorin West fuel stations (WFS) were pH, colour, electrical conductivity, turbidity, total dissolved solids (TDS), total hardness (TH), total iron (TI), copper, manganese, nitrate, chloride, TPHC, chemical oxygen demand (COD) and biological oxygen demand (BOD).The best average pH was obtained for WFS at 7.01 and lowest TPHC. Data analysis showed that factor area and location accounted for 51.17% (BOD), 62.75% (COD) and 38.51% (TPHC) of open wells within Ilorin Metropolitan area.

  • Changes in the liver of African catfish, Clarias gariepinus juveniles
           exposed to sub-lethal concentrations of glyphosate

    • Authors: J.O. Cheikyula, J.A. Umaru, A. Ategha
      Pages: 39 - 44
      Abstract: This study was undertaken to determine the histological changes in the liver of the African catfish, Clarias gariepinus exposed to sub-lethal concentrations glyphosate. One hundred (100) African Catfish (C. gariepinus) juveniles were exposed to increasing glyphosate concentrations of 0.00mg/l, 20.00mg/l, 34.00mg/l, and 56.00mg/l glyphosate with replicates for a period of 28 days in the General Purpose Laboratory of the Department of Fisheries and Aquaculture of Joseph Sarwuan Tarka University Makurdi, Nigeria. Histological changes observed in the livers were cell vacuolization, degeneration of hepatocytes, haemorrhage and ultimately necrosis. The severity of these changes increased with concentration of glyphosate from 0.00 – 56.00 mg. There was no significant difference (P>0.05) between temperature and pH in the water quality parameters of the treatments, but there was a significant difference (P<0.05), in Dissolved Oxygen (DO), Total Dissolved Solids (TDS), and Electrical Conductivity (EC) where they all decreased with increasing concentration of glyphosate.

  • Preliminary investigation effects of physical mutagen (x-rays) on
           germination and morphological parameters of Dennettia tripetala bak.f at
           early growth

    • Authors: S.A. Odeyemi, O.O. Ovuike, C.O. Ezekwe
      Pages: 45 - 53
      Abstract: Dennettia tripetala is a slow growing plant species. It has many medicinal uses. Fresh fruits of D. tripetala were collected from a mother tree. The seeds were exposed to different few x-ray doses using medical x-ray device. The same soil medium was used to raise the seedlings. Experiment was arranged in a Completely Randomized Design inside a greenhouse with five replicates. It was carried out for the period of thirteen months. Data on germination percent and morphological parameters such as root length, seedling height, number of leaf (leaf production), leaf area, basal diameter were taken for the statistical analysis. High germination percent was induced by the different doses (1,2,4,6 and 8 MGy) of x-rays. Germination occurred in control seeds and seeds treated with 6 MGy after 19 days of sowing, but it delayed to twenty-three days in other treatments (1, 2, 4 and 8 MGy). The highest mean germination (93.3 %) was recorded among the treated seeds. The least mean germination (72.3 %) was recorded in control. In this preliminary study, it was deduced that the response of each morphological parameter to the doses were varied. Some parameters were stimulated by some doses and some parameters were not stimulated by some doses of X-rays.

      Abstract: This study determined the chemical properties of biochar amendments and the performance of two maize varieties grown on the soil. The seeds of two improved varieties of OLOYIN /SW1 and SWAN-1-SR-Y were used while the local breed was obtained from a local market. Treatment consisted of two soil amendment of biochar from 100% Maize residue (MAS) and 100% African Teak (AFT) applied at same rate (10tha-1) with zero biochar application as the control. Results were analyzed using Analysis of Variance (ANOVA) and their treatment means were separated by Duncan’s Multiple Range Test at p < 0.05.The organic carbon, total nitrogen and phosphorus for the two amendments used were 47.60, 3.70, 47.81 g kg-1 for maize residue, and 44.30, 3.20 and 23.76 g kg-1 for African Teak. Highest mean plant height, stem girth and number of leaves were 112 cm, 4.90 cm and 9.00 cm were obtained in the OLOYIN when equal proportion of maize residue and African Teak biochars was applied. However, lower growth component values were obtained for the local variety. The highest mean maize grain yield of 279.4 (g) in OLOYIN followed by 243.3 (g) in SWAM -1-SR-Y while the least yield was recorded in the local variety. Also, highest protein (99.7 %), (93.4 ± 0.12%) and vitamin C (27.43, 27.25 mg kg-1) were obtained for the harvested two improved varieties when compared with the local one.

  • Effect of elephants and other ungulates on the vegetation in Serengeti
           National Park in Tanzania

    • Authors: F. Wilson, E.P. Mhache
      Pages: 74 - 83
      Abstract: This study assessed the effects of elephants and other ungulates on the vegetation in Northern Part of Serengeti National Park (SENAPA) in Tanzania. This study is peculiar since it assessed the effects of elephants and other ungulates on the vegetation in Northern Part of SENAPA which is missing in the literature. The objectives were to determine plant species composition in the Northern Part of SENAPA, examine the effects of elephants and other ungulates on vegetation in the Northern Part of SENAPA and determine plant species damaged by elephants and other ungulates in the Northern part of SENAPA. The study adopted descriptive explanatory research design. Data was collected by transect walks, interviews, questionnaires, observations and documentary literature review. The data were organized and analysed using Statistical Package for Social Sciences Computer Program Version 22, Micro-Soft Excel and content analysis. Findings indicated that, the most plant species composition in the northern part of Serengeti National Park were Vachellia xathophloea, Senegalia polycantha, Shrub vegetation, open savanna grassland and woodland species, Vachellia tortilis, Vachellia drepanolobium, Sclerocarya birrea, Lannea schweinfurthii, Vachellia Africana, Commiphora species, Brachystegia species, Salvadora persica and Vachellia nilotica. Effects of elephants and other ungulates were manifested in the death of grasses and vegetation structure, uprooting of plants, breaking tree branches, toppling of trees, stripping barks of trees and seeds dispersal. Furthermore, findings revealed that, different plant species were damaged by ungulates between paths or trails and habitats. The conclusion from the study is that, elephants and other ungulates (giraffe, rhinoceros, wildebeest, hippopotamus and buffalo) negatively affect the vegetations in SENAPA. Therefore, the study recommended the need for plant species inventory and close monitoring of changes in vegetation composition and structure and the construction of an artificial water point in the northern part of SENAPA which will reduce the impacts of elephants and other ungulates on vegetation.

  • Developing diameter distribution models in Ukpon rainforest reserve of
           Cross River State, Nigeria

    • Authors: S.E. Bassey , V.A.J. Adekunle
      Pages: 84 – - 84 –
      Abstract: The aim of this study is to provide the most appropriate model for tree distribution into diameter classes in Ukpon tropical rainforest reserve of Cross River State, Nigeria. Systematic line transect was used to lay sample plots. Two transects of 1500m in length with a distance of at least 500m between the two parallel transects were used for this study. Sample plots of 50m x 50m in size were laid in alternate along each transect at 100m interval and thus, summing up to 10 sample plots per 1500m transect and a total of 20 sample plots in the study area. A total of 1100 individual tree species spread across 65 species belonging to 21 different tree families were measured for diameter at breast height, diameters at the base, middle and top and tree total height. The mean diameter at breast height and total height of 28.8cm and 18.6m were obtained. Mean basal area of 50.29 m2 ha-1 was obtained with a mean volume of 271.249 m3 ha-1. Easy Fit software was used for Diameter Distribution models. Three diameter distribution models were developed and validated for the reserve. However, Dagum four parameters (4P) was the more flexible among the selected diameter models in the reserve. None of the selected model was significant; meaning that each of the three models is accurate and fit for diameter prediction is the reserve. The research has provided easy to use diameter distribution models for prescription of silvicultural treatment per time in the reserve in order to enhance effective and efficient management of the reserve.

      Abstract: Heavy metals contamination has been of great concern in the last decades because of their health hazards to man and other organisms when accumulated within a biological system. This study investigated Albizia lebbeck species for removal of chromium (Cr) from contaminated soil. Pots experiment consisting of five treatments (Control: 0mg Cr/kg), (50 mg Cr/kg), (100mg Cr/ kg), (150mg Cr /kg), (200mg Cr/kg) and replicated five times in a completely randomized design were used in this study. The study was carried out for a period of 12 weeks after transplanting. Growth parameters such as seedling heights stem diameter and number of leaves were assessed at the end of the experiment. Bioaccumulation factor (BAF) and translocation factor (TF) were used to assess the phytoremediation potentials of the seedlings. Physicochemical properties of the soils; Cr concentrations in soils before and after experiment and those of the plants were determined using standard instrumentation techniques. The respective mean seedling heights, stem diameter and leaf production throughout the weeks of the experiment from the treatments were: 0mg Cr/kg (6.11-14.32cm; 0.20 - 0.30mm; 1.50 - 3.21), 50mg Cr/kg (10.56-18.67cm; 0.20 - 0.28mm; 1.60 – 3.22), 100mg Cr/kg(10.99-12.03cm; 0.21 – 0.27mm; 1.61 – 2.21), 150mg Cr /kg(11.87-15.12cm; 0.22 – 0.26mm; 1.41 – 2.32) and 200mg Cr/kg(12.02-15.78cm; 0.21 – 0.26mm; 1.10 – 2.43). There were no significant differences among the treatments for the growth parameters of the Albizia lebbeck seedlings at p≤0.05. Values of BAF (0.00-0.11) and TF (0.00-0.61) of Cr in the plants indicate low potential of this plant for phytoextraction of chromium. This study has shown that Albizia lebbeck are low- efficient plant for remediation of soil contaminated with chromium.

      Abstract: Diabetes mellitus (DM) is a group of metabolic disease characterized by hyperglycemia resulting from defects in insulin secretion, insulin action or both. Thus, the study was carried out to evaluate the potentials of the use of Raunvolfia vomitoria in the treatment of diabetic patients. The study involved the preparation and administration of an infusion produced with the leaves of Rauvolfia vomitoria to eight volunteers who already have been diagnosed to have diabetes. Futhermore 150 respondents were also selected from where Raunvolfia vomitoria was majorly planted to know their level of awareness about Diabetes mellitus. Findings showed that the diabetic patients responded positively to the Rauvolfia vomitoria infusion, in that their blood glucose level reduced considerably. Also, results showed that 94% had the knowledge of diabetes while only 4% have not heard about diabetes. 80.67% were between the ages of 15 and 30 years while 2% were between the ages of 61 and 75 years. The study proved that people are aware of diabetes mellitus but do not check their sugar level or take that aspect of their health serious except in severe conditions.

      Pages: 119 - 127
      Abstract: The present study investigates pollen fertility, chromosomes number and karyomorphology of T. catappa and T. mantaly collected from Humid Forest Research Station, Umuahia Nigeria. The study was cytologically carried out using acto-orcein for pollen fertility percentage and somatic chromosome determination. The aim was to compare the pollen fertility and karyotypes of the two species. Pollen fertility was based on stainability test. The pollen fertility percentage mean obtained in T. catappa was 87.30 %, in T. mantaly, the pollen fertility percentage mean obtained was 73.80 %. Somatic chromosome number determined for the two species was 2n = 24, haploid chromosome number was n = 12. In karyotype analysis, chromosome length was between 3.18 to 3.26 μm. Two types of chromosome centromere were observed; metacentric (m) and sub-metacentric (sm) with the karyotype formula 5m+7sm in T. catappa and 9m+3sm in T. mantaly. This study has highlighted the differences in pollen fertility and karyomorpology of the two species investigated. Findings from this study can be applied in plant breeding and conservation programme.

      Abstract: Amidst increasing evidence of climate change and its impacts on food insecurity and economic growth, the study assessed Climate change and Agriculture nexus: Modelling the impact of Carbon dioxide emission on Cereal yield in Nigeria (1961 - 2018) with a view to assessing the impact of carbon dioxide emission (Co2) on Cereal production and to contribute to the body of knowledge. The study utilized secondary data from FAOSTAT. The study utilized annual data spanning from 1961-2018 of Carbon emission, Cereal yield and Gross Domestic Product growth. Augmented Dickey-Fuller (ADF) analysis was used to make decisions on whether the variables were stationary or not. Autoregressive distributed lag method of estimation was used to examine the short-run and long-run effect of carbon emission on Cereal crop yield or performance in Nigeria. The result of the short-run model of the ARDL revealed that there was a negative relationship (-0.216025) between Carbon emission and Cereal yield in Nigeria and it’s statistically significant at 5% level of significance while the long-run model of the ARDL revealed a direct relationship (0.175135) between Cereals yields and carbon emissions (CO2), with impact statistically significant. The study concluded that there is direct relationship between Carbon dioxide emission and Cereals yields. The study recommended that efforts should be made to reduce the amount CO2 or determine the optimal value of CO2 required in the atmosphere to support plant photosynthesis for future crop production especially in low income countries with a relatively high population.

  • Common invasion of non-native plant species and their co-occurrence in an
           urban area of Ondo State, Nigeria

    • Authors: B.E. Omomoh, G.E. Ogunsanwo, G.F. Akomolafe , L. Brown
      Pages: 135 - 153
      Abstract: Urban development is a significant contributor to the loss of biodiversity. Biological invasion is a consequence of urban development where invasive species appear singly or in multiple following unprecedented disturbance. The current study was carried out to assess the presence and impact of the prevailing invasive non-native plant species co-habiting in the Federal University of Technology, Akure, Nigeria. Thirty-two (32) quadrants were systematically laid out to measure the species diversity and species composition of non-native plants across the University landscape. The species abundance of invasive non-native plants found within the quadrants was measured using the diversity indices. The Shannon–Wiener index (H) value was low in all the sites except Centre for Research and Development (CERAD) which was relatively high with 0.31 values. A one-way ANOVA (Duncan, P>0.05) shows that the Shannon-Wiener value and the relative density of the invasive non-native species had no significant difference among the nine selected sites; Forest Plantation (FP), Wild Park (WP), Teaching and Research Farm (T&RF), West African Science Service Centre on Climate Change and Adapted Land Use (WASKA), Centre for Research and Development (CERAD), University Senate (US), New Undergraduate Hostel (NUH), New Postgraduate Hostel (NPH) and New Road (NR). It was observed from the result that ten different instances of invasive non-native species colonized and dominated a particular study area following disturbance. In summary, it was observed that the infestation of these plant species is currently affecting the indigenous plant growth and survival at every season of the year. However, the study shows that biological control is easier done when a single species forms a colony in a site than when it is systemically spread across all areas.

      Abstract: The study looked at the water quality of the River Kaduna using the Canadian Council of Ministers of the Environment (CCME) Water Quality Index. The study covered both raining and dry seasons in 10 sampling points. Water parameters analyzed were turbidity. Zn, Pb, Cd, Cr, Cu, Mn, Fe, dissolved oxygen, electrical conductivity, pH, TDS and Ni using standard laboratory techniques. The data obtained were used to develop Water Quality Index (WQI) across the 10 sampling points. The WQI reveals that the water quality at Barnawa, Kudenda, Tudun Wada, Makera and Anguwn Muazu were poor as their index values ranged between 31.8 – 42 while the other locations Kawo, Anguwun Dosa, Malali, Kigo and Anguwn Rimi were marginal as their index ranged between 45 – 61.3. It is recommended that pollution be controlled at the source.
