Opis:
This study focused on the contribution of NTFPs species to the livelihood of Mokwa people, Niger state. It was undertaken to ascertain the proportion of humans involved in the exploitation of NTFPs in the study area, to determine the types of NTFPs exploited and their roles in the lives of the communities and to determine the actual contribution of NTFPs species to the livelihood of the Mokwa people. Data were collected using structured questionnaire and oral interviews to acquire information from sampled members of the Mokwa LGA communities. The data was analyzed using descriptive statistics (tables, chart, and graphs). The findings from this study indicate that NTFPs are abundant in the study area and are found in all the forested land areas within the communities. NTFPs collection for utilization is usually carried out throughout the year. All the respondents in Ja’agi, Kudu, Kpaki, and Mokwa town collect and use the NTFPs in food preparation for the family and for other purposes. The number of households involved in the collection of NTFPs was highest in the Ja’agi community (95%), while only (28%) households were involved in Mokwa town. The chi-square test revealed that there were high significant differences (P>0.05) between the number of respondents involved in the collection and non-collection of NTFPs in Mokwa LGA. Twenty (20) plant by-products and fruits were the major types of NTFPs being collected. Most NTFPs species were of medicinal plants, while some supplement everyday meals. It should be noted that Mokwa LGA communities earn some money from the collection of NTFPs - especially from plants such as Vitellaria paradoxa (73%) Pakia biglobosa (16%), and Mangifera indica (4%). Lack of jobs in the government established institutions is the major problem facing the communities. It is, therefore, recommended that provision of jobs and business opportunities will help improve the living standard of the people and hence reduce their effect on the forest resources.

Opis:
Most indigenous people have acquired expertise in the use of medicinal plants, but information on the utilization of the medicinal plants are poorly documented. Thus, this study deals with the ethnobotanical survey of medicinal plants used in treating viral infections in Saki West Local Government Area, Oyo State. Data was collected using structured questionnaires and oral interviews to acquire information from selected members of Saki West Local Government Area. A total of sixty (60) structured questionnaires were given randomly to respondents in the selected villages in the study area. Data were analyzed using descriptive statistics. The finding shows that the majority of the respondents were females (61.7%). Moreover, 50 % of the respondents were from the age group of 31 to 40 (also the largest group). In addition, a majority (88.3%) of the respondents were married, and only a few (16.7%) had no formal education. Furthermore, the major occupation of the respondents was herb selling (35.0%). The findings on the various plant parts utilized for herbal medicine indicated that the leaves, stem bark and whole root were the most commonly used parts. Most of the respondents also prepared herbal medicine by decoction. What is more, oral ingestion (drinking) was found to be the most (70.0%) preferred mode of administration in the study area. Finally, the major problem encountered while acquiring medicinal plants was wild animal threat. This work indicated that there is a need for an ethnobotanical survey in every state of the nation on the medicinal plants used in the treatment of viral infection.

Opis:
Individual tree growth models are important decision-making tools in forestry. This study evaluated the predictive ability for basal area, of a Java program derived from the algorithm of gamma distribution function. The input value was diameter at breast height. In generating and testing the program, a stratified random sampling technique was used to select four different age classes of teak plantation, namely: 11, 13, 22 and 59 years-old, respectively. Complete enumeration of trees (n = 433) was done for all the plots selected. Diameter at breast height (DBH) was measured with the aid of diameter girth tape, which was also used for basal area computation. Data obtained were processed into tree and stand levels. Parameters α and β for Gamma Distribution function (GDF) were estimated from growth data. The java program was then written based on the algorithm of Gamma distribution function for α, β and n parameters. Values of diameter at breast height fitted into the Java program shows that it was able to predict the basal area. Therefore, the predictive ability of the developed Java Program for basal area of individual and full stand teak trees demonstrates that it can be used for prediction of yield in forest stands.

Field evaluation of insect pests and pathogens associated with sesame cultivated in the Niger Delta region of Nigeria was conducted to provide baseline information on their status. The experiment was laid out in Randomized Complete Block Design. Herein, sesame seeds were obtained from the Jos and Maiduguri main markets. These were sown, then data were collected on insect species beginning three weeks after sowing (WAS) for six weeks and identified to species levels. At 10 WAS, plant parasitic nematodes (PPNs) were extracted from both root and soil samples in the rhizosphere of sesame, using the modified Baermann method. Plant parasitic nematodes were identified to generic level. Infected plant parts from field were thoroughly washed, disinfected and plated on PDA, and subsequently incubated at 25 ± 2 °C. Fungal pathogens were isolated, identified and checked for their viability and purity. Data obtained were subjected to both parametric and none parametric analyses. Insect species collected included Leptaulaca fissicolis, Gryllus bimaculatus, Apogonia nitidula, Trilophida conturbata, Elis sp. amongst others. A total of six genera of PPNs, Helicotylenchus, Pratylenchus, Scutellonema, Gracilacus, Meloidogyne and Tylenchus were associated with Sesame. Gracilacus and Pratylenchus had the highest population in soil (37.5%) and roots (37.5%). Three fungal isolates, namely, Fusarium oxysporum, Fusarium solani and Trichoderma sp, were consistently isolated from the plant parts - with Fusarium oxysporum and Fusarium solani being pathogenic. Knowledge of these insect pests and pathogens will aid in their management.

Opis:
Few studies have shown that Cnestis ferruginea possess some therapeutic properties. The present study was aimed screening the extracts of the fruits and leaves of Cnestis ferruginea for phytochemicals using crude screening and gas chromatography-mass spectrophotometer (GC-MS) methods, and also antimicrobial activity against clinical isolates. Preparation of the extracts (aqueous and ethanolic), identification of isolates, and antimicrobial sensitivity were done using previously reported standard methodologies. Replicate readings for the antimicrobial sensitivity were analysed using analysis of variance at 95% level of significance. The result of the crude qualitative screening revealed the presence of phenol, terpenes, alkaloids, saponins, tannin and polyphenol in various amounts in both the leaves and fruits. Quantitative analysis using GC-MS revealed a total of 14 similar phytochemicals each in the leaves and fruits of the study plant in varying amounts. In the fruits, phenol had the highest concentration of 15.01%, followed by terpenes (10.64%), alkaloid (5.43%), and tannins (5.16%). Others were anthocyanins, phytate, phytosterol, steroids, saponins, cardiac glycosides, oxalate, flavonoids, cyanogenic glycosides and coumarin with concentrations that ranged from to 0.01- 4.21%. On the other hand, in the leaves, alkaloids had the highest concentration of 31.62%, followed by phenol (20.59%), phytate (15.18%), and tannin (12.34%). Others include were flavonoid, terpenes, phytosterol, cardiac glycosides, saponins, cyanogenic glycosides, oxalate, anthocyanins, steroids and coumarin with concentrations that ranged from 0.16-8.45%. The isolates were identified as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Proteus spp. The results of the antimicrobial sensitivity revealed varying zones of inhibitions; however, it increased as the concentration of the extract increased. The observed highest zones of inhibitions were 33.86 mm for the fruit ethanolic extract and 30.56 mm for the aqueous extract of the leaves against Proteus and Staphylococcus aureus, respectively.

Opis:
With advances in next generation sequencing and microscopy, a clearer picture is beginning to emerge about the predatory properties of Bdellovibrio and like organisms (BALOs). BALOs are Gram negative microorganisms which are natural predators of other Gram-negative microorganisms, especially those associated with diseases in humans and animals. One of the limitations of BALOs is their inability to prey upon Gram-positive organisms that cause the bulk of human diseases. The global spread of antibiotics resistance to almost every group of antibiotics, and the paucity of newer antibiotics since 1970s is very worrisome. The ability of BALOs to decimate pathogen populations principally those carrying multidrug résistance genes coupled with the increasing rate of antibiotics resistance, has made them an attractive option as biocontrol agents. With the absence of resistance to BALOs, these much anticipated “magic bullets” will certainly find more and more applications in health, agriculture, medicine and environment in the nearest future.

Opis:
Telfairia occidentalis leaves and Cucumis sativus (cucumber) are vegetables that grow best in Tropical countries like Nigeria and have good nutritional properties but are highly perishable. Both vegetables were evaluated for wine production singly and in composite forms using palm wine and Baker’s yeast strains. In addition to wine production, the vegetables were screened for phytochemicals, anti-nutrients and nutrients (proximate composition, elements and vitamins) using standard methodologies. Proximate composition (g/100g dry matter) revealed that T. occidentalis leaves had moisture content, ash, protein, fat, fibre and carbohydrate contents of 86.60±0.10, 5.72±0.02, 4.30±0.10, 0.97±0.02, 6.30±0.10 and 82.45±0.02, respectively. In contrast, Cucumis sativus had a moisture content, ash, protein, fat, fibre and carbohydrate contents of 96.75±0.01, 5.40±0.02, 13.50±0.02, 10.30±0.10, and 66.12±0.01, respectively. Both plants contained various phytochemicals, including alkaloids, glycosides, saponins, tannins, flavonoids, reducing compounds and polyphenol, but not anthraquinones and phlabotanins. However, on quantification, reducing compounds and polyphenol recorded the highest concentrations. Vitamins A and C were detected in both samples. C. sativus had high amounts of K, P, and Mg and moderate amounts of Ca, Na, Cu, Fe and Mg. T. occidentalis leaves had moderate amounts of Ca, Zn, Fe, Mg, Ca and Na. Anti-nutrients levels were all below allowable regulatory limits for vegetables. Density, pH and alcohol values ranged from 0.20 - 0.99, 0.30- 4.6 and 1.95 - 9.94%, respectively. Sensory evaluation of the wine samples showed that wine produced from 70% fluted pumpkin and 30% cucumber had the best scores in terms of acceptability, taste, aroma and appearance. Given the findings in the study, wine production using tropical vegetables could double as a viable alternative to tropical fruits and also help to curb post-harvest losses commonly experienced in the tropics.

This study was aimed at determining the optimum yield of bioethanol (as biofuel and industrial chemical) from yam, potato, watermelon and pineapple peels using different concentrations of hydrochloric acid (HCl). Results obtained from acid hydrolysis, fermentation and distillation revealed that yam peel gave the highest quantity of glucose (38.7±0.90%) and ethanol (18.40±0.18%) at an acid concentration of 1.5M, watermelon peel equally recorded a highest yield of glucose (18.3±0.50%) and ethanol (8.35±0.14%) at 1.5M. For potato peel, the highest quantity of glucose (33.8±1.10%), and ethanol (18.23±0.04%) was at 2.0M, this concentration (2.0M) was equally the optimum for pineapple peel, the highest glucose concentration and ethanol yield of which was 24.5±0.62% and 11.44±0.29% respectively. Utilizing these agro-wastes for the production of bioethanol provides a means of recycling these biological wastes which are normally prone to rapid microbial spoilage.

Opis:
This study focused on bird species richness and diversity in Borgu sector, Kainji Lake National Park, Nigeria. The study was undertaken to derive information on the species of birds utilizing the study area, and to determine the relative abundance and diversity of birds in the study area. The Line transect methods was used for the study. The result revealed that the present number and kinds of birds species in all the ranges sampled is very low, with Range 4 having the highest bird’s species richness of (22.29%). A total of 3255 birds were inventoried in all the ranges. These belonged to 44 species from 28 families. Family Ardeidae contain the highest number of 593 birds, followed by the family Sturnidae and Numididae - having 392 and 351 birds, respectively. The findings indicate that birds’ abundance is very low with many bird species displaying 0% relative abundance. The low abundance and diversity of birds indicates that Kainji Lake National Park birds in relation to habitat characteristics is very poor. Furthermore, the result from the test prediction Output shows that the estimators predict that (after 5 samples) there will be 41 birds’ family species in the habitat in future, since they (ACE, ICE, Chao2, Jack2) level off at 41. The result indicate that only the same birds species, instead of new birds species are presently seen in Kainji Lake National Park, which are poorly represented among 28 families sampled. It is, therefore, recommended that environmental education campaign on birds’ conservation and protection should be carried out in the communities around the park so as to persuade residents to stop killing birds.

Our results indicate that the optimum qe was 15.982 mg/g by Co 25 mg/L, H 4.1cm and Q 8 mL/min. In the study, qe was observed to decrease with increase in Co and Q. The optimum bed height was 4.1cm. Our experimental data were modelled by applying Thomas and Yoon-Nelson kinetic models. Correlation coefficient, R2 values (generally above 0.85) show that the two kinetic approaches provide an effective model of the experimental data. We conclude that oil palm fruit mesocarpfibre has potential as a precursor for production of carbon for acid-dye removal from wastewater.

Oil was extracted from the dehulled seeds of Lagneraria siceraria (bottle gourd) and analysed for physico-chemical properties, as well a fatty acid composition. Standard procedures were employed in all analysis. The seed oil was liquid at room temperature with percentage yield (23.65%). The oil was characterized in terms of specific gravity (0.918 g/cm3), refractive index (1.34), viscosity (26.46 X 103 poise), melting point (11-14.5 °C), moisture content (0.18%), saponification value (203.36 mg KOH/g), unsaponifiable matter (7.13%), iodine value (46.1 g/100g), peroxide value (7.5 meq/kg), free fatty acid value (18.42%), acid value (60.02 mg KOH/g) and ester value (143.34 mg KOH/g). It was also classified as non- drying (iodine value ˂115 g/100 g). The peroxide value indicates that the oil is less prone to rancidity with iodine value less than 30meq/kg. The high saponification value qualifies it for use in the manufacture of soaps and shampoos. Four classes of fatty acid were identified in the oil: palmitic acid (C16:1) (13.5 ± 0.21), stearic acid (C18:1) (6.5 ± 0.96), oleic acid (C18:1) (11.6 ± 0.62) and linoleic acid (C18:2) (68.4 ± 0.13). Linoleic acid was the most abundant fatty acid in the oil. The fatty acid content of the oil reveals that L. Siceraria seed oil could be a rich source of oil for domestic and industrial purposes if exploited.

This research focuses on the ground water quality index in Ado-Ekiti State, Nigeria. Groundwater sample wells were randomly collected and their spatial locations captured using a handheld GPS. Water samples were taken from 45 wells and their physio-chemical properties were analyzed in the laboratory. Spatial distribution maps of the water quality parameters were then developed. Herein, the Kriging method of interpolation from geospatial analyst wizard in Esri ArcGIS software was deployed in the generation of thematic maps of water quality parameters. A drinking water quality index was subsequently developed to describe the overall quality of groundwater in the study area. Laboratory analysis of 34 wells showed water of acceptable use as it conforms to WHO standard, while 11 wells were found to have unsuitable water for domestic use. The results further show spatial variation in the water quality. The south central depicts poor water quality, fair water quality in the south-east, while the North, north east, north-west down to the south west depicted the best water quality.

Opis:
The human microbiome is a complex collection of microorganisms, including their genes and the metabolites colonizing the human body, and playing various functions in health and disease. The arrival of culture-independent molecular techniques such as metagenomics, transcriptomics, proteomics, and metabolomics have removed the limitations imposed by culture-dependent techniques. These advanced techniques have also brought about some paradigm shifts in what is known about the structural and functional diversities of the human microbiome in health and disease. The dynamics of the human microbiome is implicated in a number of human gastrointestinal and non-gastrointestinal diseases. This makes it a contemporary issue in biological and medical sciences. Of interest, some applications have already emerged for the human microbiome. These include being the source of antimicrobial substances, faecal microbiome therapy, probiotics, prebiotics and phage therapy. Given that a number of factors can alter the host microbiome - such as environment, lifestyle, stage of life, occupation, mode of delivery, therapy and so on, there is a need for more human microbiome projects that will help to capture these diversities in various continents. Furthermore, for the full impact of the various applications (both potentials and current) of human microbiome to be felt, there is need for more studies that will fully elucidate their physiology in humans.

Opis:
This research investigated the inhibition behavior of Spondias mombin leaf (SML) extracts in 0.1 M HCl solution on mild steel at various concentrations and temperatures. The result reveals that the inhibition efficiency of the extract on the mild steel sheet increases with increasing concentration of the extract and decreases with increase in temperature. Therefore, the adsorption mechanism of the extract on the mild steel surface is physical. Calculated Correlation Coefficient (R2) values show that the process follows a Freundlich adsorption isotherm. The proposed temperature coefficient equation of adsorption mechanism was found to be appropriate.
