Abstract:

Biodiversity provides essential services like provision of food, medicine, pest and disease control, pollination, protection from natural hazards, regulation of climate and air quality, nutrient recycling, cultural and aesthetic values and source of income. Due to the neglect of agriculture, there is massive poverty in Nigeria. Conservation of biodiversity would alleviate poverty through sustainable agriculture. In order to conserve biodiversity while reducing poverty and increasing human well-being and development to achieve MDGs, biodiversity must become part of government development policies.

Abstract:

Biodiversity accounts for the variability among living organisms and its conservation presents insights for mitigating the problem of depletion or exhaustion of biological resources. From the simplest level of genes, species, and ecosystems; biodiversity provides a wide range of goods and services for survival with potential direct or indirect utilization by humans. Biodiversity is key as it constitutes the rich biological resources that typically measures all variations at the genetic, species and ecosystem level and is particularly important for nutrient recycling in soil fertility maintenance; purification of water and air and detoxification of wastes as well as for mitigating pollution and moderation of floods and droughts. It is also invaluable for protecting watersheds and combating erosion; stabilization of climate; and control of pests and diseases. The diversity of insect species is unparalleled being estimated at 1.5 million species but biodiversity is generally threatened in Nigeria by high population growth rate, poverty, policy and legislation constraints as well as poor land use planning and climate change among others. The direct threats to biodiversity in Nigeria include habitat degradation, unsustainable agricultural practices and unsustainable harvesting of biological resources among others. The major approach to biodiversity conservation in Nigeria is the protected-area system and the establishment of a National Insect Museum to be domiciled in one of the Federal Universities is key.

Abstract:

There are generally no acceptable views on the conservation of biodiversity because there are no known best approaches to that. This has presented a challenge on what and how to conserve in developing countries like Nigeria. This paper used a multi-criteria decision-making model based on the Analytic Hierarchy Process (AHP) to elicit experts’ opinions on biodiversity conservation approaches and their corresponding conservation targets. The rationality of the experts was checked by measuring their consistency in the decision-making process. A greedy search algorithm based on linear programming application was also used for resource allocation. This technique is holistic and allows the decision maker to consider all pertinent factors. The approach allows policy makers to integrate worldviews; culture; diverse flexibility of concerned communities and other stakeholders in identifying conservation practices to achieve sustainability. In terms of current performance for the biodiversity conservation approaches; the conservation experts rated their performance on Ecosystem-service-based approach high with the priority index of 0.460. Their performances on Area- and Species-based approaches are ranked second and third with priority indexes of 0.288 and 0.252 respectively. Conversely; in the case of expectations; Ecosystem service is the most important with a priority index of 0.438 followed by Area-based with a priority index of 0.353 and Species–based with a priority index of 0.209. The Ecosystem-service based approach has the highest contribution coefficient. Resources are allocated accordingly; in form of capacity building; based on the priorities that were obtained. The research is a rights-based tool for capacity building; and a paradigm shift from the purely scientific approach to decision-making. It is designed to bridge a scientific gap between policy formulation and resource allocation in biodiversity conservation.

Abstract:

Biodiversity refers to the varieties, multiplicity, and diversity of life in the ecosystem. It is being lost on a daily basis in Nigeria’s Niger Delta. This is as a result of the environmental degradation caused by oil exploration and gas activities. In the process of drilling for oil and exploring for gas resources, the natural environment such as plants, animals and their communities is destroyed and endangered. Oil exploration activities continue unabated in the Niger Delta. There is need to combat biodiversity loss if not many of the benefits from biodiversity will be lost. With critical analysis the philosophy of deep ecology is examined and presented as having potentials to contribute to conserving biodiversity in Nigeria’s Niger Delta. The paper concludes that there is vital need to preserve biodiversity using deep ecology values. Keywords: Deep ecology, biodiversity, conservation, Niger Delta, Nigeria, and Philosophy

Abstract:

Comprehensive biodiversity assessment of moths in Nigeria rely greatly on accurate species identification. While most of the Nigerian moths are identified effortlessly using their morphological traits, some taxa are morphologically indistinguishable, which makes it difficult for taxon diagnosis. We investigated the efficiency of the DNA barcode, a fragment of the mitochondrial Cytochrome C oxidase subunit I, as a tool for the identification of Nigerian moths. We barcoded 152 individuals comprising 18 morphospecies collected from one of the remaining and threatened rainforest blocks of Nigeria – the Cross River National Park. Phenetic neighbor-joining tree and phylogenetic Maximum Likelihood approach were employed for the molecular-based species identification. Results showed that DNA barcodes enabled species-level identification of most of the individuals collected from the Park. Additionally, DNA barcoding unraveled the presence of at least six potential new and yet undescribed species—Amnemopsyche sp., Arctia sp., Deinypena sp., Hodebertia sp., Otroeda sp., and Palpita sp. The phylogenetic Maximum Likelihood using the combined dataset of all the newly assembled sequences from Nigeria showed that all species formed unique clades. The phylogenetic analyses provided evidence of population divergence in Euchromia lethe, Nyctemera leuconoe, and Deinypena lacista. This study thus illustrates the efficacy of DNA barcoding for species identification and discovery of potential new species, which demonstrates its relevance in biodiversity documentation of Nigerian moths. Future work should, therefore, extend to the creation of an exhaustive DNA barcode reference library comprising all species of moths from Nigeria to have a comprehensive insight on the diversity of moths in the country. Finally, we propose integrated taxonomic methods that would combine morphological, ecological, and molecular data in the identification and diversity studies of moths in Nigeria.

Abstract:

Africa has been tagged a festival continent as year in year out, towns and villages witness cultural festivals throughout the year. These festivals are mostly concerned with resources conservation and utilization. The adoption of Western Model of conserving biodiversity in the trickle-down fashion has failed to yield reasonable result; whereas traditional festivals epitomize indigenous people’s respect and reverence for, and pragmatic understanding of, their natural environment. The quest of conserving biodiversity for sustainable development therefore calls for the integration of traditional festivals in sustainable resource management framework. In spite of the invaluable potentials of traditional festivals in biodiversity conservation as an indigenous resource management system, it has not been given a prominent place in the modern day scientific resource management framework. Using ethnographic research design, the paper exploits the natural resources conservation potentials of Osun-Osogbo and Argungun fishing festivals in Nigeria. Data are collected from archival, ethnographic and internet materials, as well as text books, pictures and information through interviews and observations. The paper presents an analysis of ways through which policy frameworks can benefit from festivals and how a wide audience can be reached with biodiversity conservation messages for the purpose of creating awareness. The paper develops a framework for ecosystem based adaptation, using indigenous festivals for the purpose of replicating it in every other community where such festivals do not exist and integrating it in festivals that are not based on natural resource conservation.

Abstract:

This research surveyed some socio-economic activities of communities around Pandam Game Reserve (PGR) central Nigeria to determine their implications for biodiversity Conservation in PGR. Data were collected using structured questionnaires and field observations. Results showed a 100% response to questionnaires administered. Eighty three percent (83%) of the respondents were males while 17% were females. Eighty percent (80%) attended at least primary school level of education while 20% had no form of formal education. Prominent among occupation of respondents was farming with 40% and the occupation of respondents with list response was hunting with 1%. Field observations showed the presence of the following human activities: logging, firewood collection, fishing, farm encroachment, cattle grazing and poaching. The implication of these socio-economic activities in PGR if left uncontrolled could result to biodiversity lost. A multi-stakeholder approach and participatory management of the reserve which will consider the socio-economic concerns of locals have been suggested as a critical component for building cooperation. These if properly exploited is believed will contribute substantially to biodiversity sustainability in PGR. Keywords: Communities, Biodiversity, Conservation, Pandam Game Reserve

Abstract:

The impact of soil erosion on the conservation of biodiversity in Isiala Ngwa North LGA, Southeastern Nigeria was examined. Data were obtained through focus group discussions and plant species enumeration. Diversity indices of plant species were derived from quadrat analysis using Shannon Wiener’s diversity index. Eighteen soil samples were collected from agricultural erosion sites in the study area and analysed in the laboratory. The results obtained were analysed using principal component analysis (PCA). The rotated component matrix of the soil properties, as well as plant and animal diversity indices from the PCA isolated three components that together explained 93.821% of the observed variation. The results show that bush clearing in the form of slash and burn, uncoordinated bush burning and harvesting of plant species are the activities that cause soil erosion in the study area. Agro-forestry, bush fallowing, reforestation and legislation on indiscriminate harvesting of plant species were recommended.

Abstract:

Abstract Within Enugu and Anambra States, Nigeria, identification of fishes has been based on morphological traits and do not account for existing biodiversity. For DNA barcoding, assessment of biodiversity, conservation and fishery management, 44 fish sampled from Enugu and Anambra States were isolated, amplified and sequenced with mitochondrial cytochrome oxidase subunit I (COI). Twenty groups clustering at 100% bootstrap value including monophyletic ones were identified. The phylogenetic diversity (PD) ranged from 0.0397 (Synodontis obesus) to 0.2147 (Parachanna obscura). The highest percentage of genetic distance based on Kimura 2-parameter was 37.00 ± 0.0400. Intergeneric distances ranged from 15.8000 to 37.0000%. Congeneric distances were 6.9000 ± 0.0140–28.1000 ± 0.0380, with Synodontis as the existing synonymous genus. Confamilial distances in percentage were 16.0000 ± 0.0140 and 25.7000 ± 0.0300. Forty-two haplotypes and haplotype diversity of 0.9990 ± 0.0003 were detected. Nucleotide diversity was 0.7372, while Fu and Li’s D* test statistic was 2.1743 (P < 0.02). Tajima’s D was 0.2424 (P > 0.10) and nucleotide frequencies were C (17.70%), T (29.40%), A (24.82%), G (18.04%) and A + T (54.22%). Transitional mutations were more than transversions. Twenty species (99–100%) were identified with the e-value, maximum coverage and bit-score of 1e−43, 99–100 and 185–1194, respectively. Seventeen genera and 12 families were found and Clariidae (n = 14) was the most dominant among other families. The fish species resolution, diversity assessment and phylogenetic relationships were successfully obtained with the COI marker. Clariidae had the highest number of genera and families. Phylogenetic diversity analysis identified Parachanna obscura as the most evolutionarily divergent one. This study will contribute to fishery management, and conservation of freshwater fishes in Enugu and Anambra States, Nigeria.

Abstract:

<p>Deforestation occurs around the world; though tropical rainforests are particularly targeted, it is considered to be one of the contributing factors to global climate change. While Nigeria is probably best known today for its oil deposits, according to the World Resources Institute, Nigeria is home to 4,715 different types of plant species, and over 550 species of breeding birds and mammals, making it one of the most ecologically vibrant places of the planet. It is also one of the most populous country with appalling deforestation record. This situation is hence making our ecosystems, biodiversity, agriculture and other natural endowments highly unsecured. The Forest provides excellent resources for bees and beekeeping, and bees are a vital part of forest ecosystems. Bees are essential for sustaining our environment because they</p><p>Pollinate flowering plants and conserves biological biodiversity along with their products (honey, propolis, bee wax, royal jelly and bee venom) which are beneficial to man. Conservation of the forest is therefore imperative for sustainable beekeeping. The study reviews the different causes of climate change and how they affect different natural forest activities which are weather-dependent. Also how climate change and other causes (both natural and man-made) lead to deforestation, which in turn distort sustainable honey production in Nigeria. Different sustainable measures hoped to alleviate the effects of climate change and deforestation where also discussed. </p>

Abstract:

This study seeks to address the need for diversity in covering environmental issues given that they are multi-dimensional. Journalists have the responsibility of determining what contents are hyped in the media, by so doing they influence audiencesâ€™ reaction to issues. Thus the agenda setting theory of the media was used as the framework for this study as it helped explain why the press emphasizes certain environmental issues over others. Content analysis was employed to analyze four leading Nigerian newspapers to determine their priorities in covering environmental issues. It was found that despite the much pressing local problems like waste disposal/management, pollution, deforestation, open defecation, poor urban planning, nature conservation, loss of biodiversity, over logging etc, the Nigerian press devotes much attention to climate change/global warming coverage. This seems to be a misplaced priority as Nigeria is said to contribute less than one percent of carbon emission that causes global warming. This study argues that while it is necessary to report climate change, it should not be at the expense of more pressing local issues that the citizens have to contend with in their daily living. There is therefore need to devote ample spaces and time to these local issues otherwise the coverage of environmental issues in Nigeria will be akin to the concept of â€œAfghanistanismâ€ where the local media approach issues from the international perspective while dealing with such issues myopically from the local angle.

Abstract:

SummaryThe scope and scale of wildlife crimes around the world have risen in intensity and complexity, yet current enforcement strategies have often not delivered desired effects on illegal activities, even within protected areas. Tackling the array of illegal activities by emphasizing law enforcement above other options is challenging and potentially unsustainable. We explored the potential for social norms, community regulations and socioeconomic factors to promote compliance with wildlife laws by interviewing 334 respondents in 28 villages that share boundaries with protected areas in Nigeria. Using an anonymous direct questioning approach, we recorded a high prevalence of non-compliance behaviours in all studied communities. Injunctive norms (i.e., perceptions of acceptable behaviour within a social group) significantly predicted compliance, as respondents with no complicit friends or family members were more likely to comply with wildlife regulations. Perceived likelihood of community-level sanctions played a more salient role than the fear of arrest by rangers in influencing compliance. In addition, non-compliance increased with number of dependents, but reduced with average monthly household income. Our study demonstrates that clear knowledge of the social norms that drive local behaviour as well as the authorities that enforce them is integral to understanding the forces that drive community involvement and participation in conservation. Incorporating local communities in planning enforcement interventions may help protect threatened species and landscapes.

Abstract:

The present study assessed the trees species diversity and the benefits that arise from their presence in five selected recreation centers in the urban area of Ibadan: Agodi Gardens, Ibadan Recreation Club, National Museum of Unity, Ibadan Golf Club and Ibadan Polo Club. The selected areas were purposively chosen due to the presence of tree species in the urban landscape. Both primary and secondary data were used for the study. Agodi Garden had in total 537 individuals, 46 tree species within 25 families. Ibadan Recreation Club had the total number of 148 trees, whereas 32 species within 22 families were represented. National Museum of Unity had a total number of 770 trees, classified in 23 species within 17 families. Ibadan Polo Club had a total number of 97 trees, 20 species and 15 families were represented. Ibadan Golf Club had a total number of 915 trees, 31 species and 9 families. Fabaceae family had the highest occurrence in Ibadan Recreation Club, National Museum of Unity, Ibadan Golf Club and Ibadan Polo Club, while Verbenaceae was more represented in Agodi Gardens. The study has shown the high occurrence of invasive species in tropical environment based on their regeneration potential. Data collected on total number of tree species, frequency of occurrence and families were subjected to descriptive analysis. A semi-structured questionnaire was used to obtain information. These centers serve as ex-situ urban centers/parks that still maintain and conserve various tree species and are important resources for social, economic and educational use. Biodiversity indices were also analyzed and it can be concluded that the type of organization and the main activity of the centers strongly influence the species diversity. The trend of Shannon-Wiener diversity index (H') showed that Ibadan Polo Club was the most diverse. Despite the higher number of individual trees encountered in NMUI, the H' value was very low, indicating the dominance of a few tree species within the area. From EH values obtained in the study, it can be concluded that trees species are most evenly distributed in IPC, followed by IRC, AG, IGC and lastly by NUMI.

Full text

Abstract:

The importance of inland fisheries sector cannot be over-emphasized and its significance in providing food security and generating local income is not in doubt. Production from inland open water capture fisheries is declining due to over-exploitation and habitat degradation. The rapidly declining catch from fish landing is a possible indication that the fish yields of most Nigerian inland waters are generally low for causes that may range from inadequate management of fisheries to degradation of water bodies. Artisanal fishing in the Niger Delta is faced with myriads of obstacles emanating from human activities; one of these problems being the menace of the commercial fishing trawlers and activities of the oil companies in the area. The local supply of fish and fishery products consists of production from the artisanal (85%), industrial (14%) and Aquaculture (1%) subsectors. The high activity level in the Niger Delta has exposed the area to the dangers of pollution of water, land and air as well as oil spills which have endangered aquatic life as well as the entire ecosystem, topography and surface vegetation leading to loss of biodiversity and conflicts. The contribution of fisheries to the nation economy is very significant in terms of employment, income generation, poverty alleviation, foreign exchange earnings and provision of raw materials for the animal feed industry. In order for biodiversity conservation to be effective, management measures must be broad based. Keywords: Inland Fisheries, Aquaculture, Over-exploitation, Sustainable, and Pollution.

Abstract:

Cross River National Park (CRNP) is a rainforest biodiversity hotspot and region of species endemism in Nigeria. It has solid minerals, valuable timber, assorted fauna species, rich agricultural lands, medicinal plants and several other plant species that are new to science. The formal establishment of the park in 1991 was anchored on the global ecological importance attached to the region. Instead of implementing the resettlement of enclave communities and a 7 year livelihoods program, as was originally proposed in the park management plan (prepared by WWF and ODNRI in 1989), the park has been concentrating on authoritarian protection as park management strategy. Using a combination of document research, participatory rural appraisal techniques and rural livelihoods survey, the study assesses the effectiveness of authoritarian protection in the midst of economic and ecological contestations in CRNP. Findings reveal that donor partners abandoned CRNP in 1995 without implementing the resettlement and buffer zone livelihoods program. This led to the explosion of commercial bush meat hunting activities in the park (despite authoritarian protection). The paper argues that authoritarian protection alone cannot save biodiversity in CRNP. It presents the perspectives and conservation standpoints of buffer zone communities on the bush meat crisis and how to address it in CRNP. It highlights the need for the creation of arenas for finding common ground on all contentious issues threatening biodiversity conservation in CRNP, the need to revisit the drawing board and donor return, and the present and future dangers facing CRNP if nothing is done.

Abstract:

Inspite of the strong aversion shown to Entomophagy (consumption of edible insects) due to civilization, insects have played an important part in the history of human nutrition in Africa, Australia, Asia and the Americas. Hundreds of species have been used as human food. Globally, about 14 insect orders contain one or more species of edible insects. Africa is one of the leading continents that consume insects as food. In Africa, insects form part of the traditional diets of millions of people and are also used as feed for their farm animals. Nowadays, Entomophagy is a major entomological research interest with focus on its future prospect for food and feed security. Nigeria, the focus of this study is very rich in forest edible insects due to its marked ecological and climatic diversity. Some of the popular edible insects are grasshoppers, caterpillars, beetle grubs and adults, winged termites, bee, wasp and ant brood as well as winged ants, cicadas, and a variety of aquatic insects. Despite their importance as food, biodiversity and conservation efforts have focused mainly on other groups of animals, ignoring the vast world of insects. Therefore, there is a compelling need to collect data on the diversity and conservation of edible insects in Africa, and to make this information available to all interested parties. This study provides information on the list and distribution of these edible insects in Nigeria, their harvesting, processing and preservation techniques, their seasonality, nutritional value and the potential for expanding the market.

Abstract:

Mushere children’s ethno-ornithology was surveyed from October to November 2015 to find out their level of bird knowledge—as well as whether and how children valued and learned about birds—in order to determine the potential role such knowledge might play in Mushere biodiversity conservation. Methods included picture elicitation exercises, free-listing, and semi-structured interviews. Our results revealed a limited knowledge of birds in Mushere children, and that bird knowledge was gendered. Girls learned through observation, while boys learned through practical bird-related activities. Learning was mostly horizontal for boys but vertical and/or oblique for girls; the most reported learning mode was through oral tradition. Farmland and garden birds were the most common groups, with birds in the families Columbidae and Estrildidae having the highest salience and frequency of mention. We suggest that this reflects the importance of ecological salience, since both groups are relatively locally abundant. The children also had a limited knowledge of cultural beliefs and uses of the birds, but valued birds as important. We argue that how much children will know and learn about any biological domain will be determined by the cultural attitudes and perceptions of that domain, and the cultural importance attached to it. We conclude that the limited knowledge of birds in Mushere children reflects Mushere cultural indifference (ornithoapatheia) to birds. We suggest that a consistent and deliberate conservation education program that will work towards encouraging ornithophilia, the love of birds, and biophilia, the love of nature, in Mushere children could be beneficial.

Abstract:

Wetlands perform a wide variety of functions that include flood control, ground water recharge, shore line stabilization, storm protection and climate moderation. However, despite these huge wetland functions, it has witnessed poor appreciation and dreadful conditions. Niger Delta has witnessed constant coastal erosion and rising sea level, this has led to large portions of the landmass being eroded. This paper aims to review some environmental effects of flooding in the Niger Delta region of Nigeria to provide the desired knowledge of role that wetlands play in reducing flood impacts. However, having witnessed the flood, the experience opened my eyes to the environmental challenges facing Niger Delta with respect to Wetlands degradation, poor perception of wetland values and functions, poor environmental practices and non-implementation of environmental regulations. This memorable experience rekindled the desire and motivation to seek a solution to wetland degradation with the aim of recognizing significance of wetlands at the centre of achieving both livelihood and biodiversity improvements to address coastal flooding problem.The study therefore concludes that wetlands are very significant in flood control and thus the conservation and restoration of wetlands, should put in place measures to reduce wetland destruction.International Journal of EnvironmentVolume-4, Issue-3, June-August 2015Page: 177-184

Abstract:

Man is using more energy, land, water, and natural resources than ever before. Population increase also leads to increasing food insecurity. In view of this, the contributions of agroforestry (AF) to enhancing food security and environmental conservation were assessed. The study was carried out in Ondo state, Nigeria, situated in the tropical rainforest ecological zone. Data were collected with pre-tested questionnaires administered to 300 farmers - household heads, randomly selected from four Local Government Areas (LGAs). Information was gathered on farmers’ awareness of and involvement in AF systems, willingness to plant, retain or take care of trees planted, farm location and sizes, tree species commonly retained/planted on farmland, major causes of deforestation, extension education in AF and other information relevant to the study. Data were analyzed using a descriptive statistics and χ2 model. Results revealed that the primary occupation of the majority of the respondents (80%) is farming. Land is mainly obtained through lease from landowners (52%). This is followed by those who inherited land (26%). Very few respondents (6%) have their farms on government land through AF (Approved Taungya System). Most farmers (67%) were willing to plant, retain and take care of trees on their farmland to provide shade for crops, for edible fruits, timber and firewood, erosion and leaching control, biodiversity conservation, reduction of global warming, and increased crop yield. Average yearly crop yield (cassava and maize) from AF farms was 750 kg/ha against 630 kg/ha for non-AF farms. Agroforestry is a means of increasing food production and at the same time, it makes wood available to rural dwellers. However, there is a need to improve both formal and informal AF education among the rural communities for agroforestry to become more widely accepted by local populations.

Abstract:

Understanding the level and distribution of genetic diversity in African locust bean (Parkia biglobosa) would strengthen breeding and conservation programmes towards domestication and sustainable use of this species. Sixteen accessions of P. globosa were assessed for variability based on seed morphology, seed protein and DNA profiling. Significant variation in seed characteristics were observed across locations. Seed protein profiling by SDS-PAGE revealed homogeneity as most bands were found common in all accessions, indicating that the protein profiles are highly conserved. Protein profiling separated the 16 accessions into four major clusters at 0.93 similarity coefficient. Most accessions grouping into Cluster 1 had a similarity coefficient of close to 100% and were from the Derived Savanna suggesting the presence of duplicates. Accessions NH/2016/P14, NH/2016/P03 and NH/2016/P04 grouped into clusters II, III and IV; respectively. Sixteen RAPD markers generated a total of 256 bands of which 63.67% were polymorphic. Gene diversity ranged from 0.41 to 0.93 and Polymorphic Information Content (PIC) from 0.39 to 0.93. The RAPD-based dendrogram separated accessions into six groups at 0.68 similarity coefficient. Based on a polymorphic seed storage protein marker a genetically distinct accession NH/2016/P04 could be exploited for breeding purposes. The homogeneity of alleles and narrow genetic base as revealed by RAPD and SDS-PAGE analyses suggests possible loss of intraspecific genetic diversity. Thus, intensification of germplasm collections across the different agroecological zones and characterization using specific markers will give a better understanding of diversity of P. biglobosa in order to enhance selection towards conservation, breeding and sustainable utilization.

Abstract:

In this study, the Bodna River was analyzed for some physicochemical parameters. The main aim of the study was to determine the effect of human activities on the physical, chemical and biological properties of the river, and to enhance systemable usage for conservation and management. The water quality parameters examined were Temperature, pH, Transparency, Salinity, Total dissolved solids (TDS), Dissolved oxygen (DO) and Electrical Conductivity (EC) for the four sampling stations from May 2018 to April 2019. There was no significant difference (p>0.05) in the pH values of the river ranging between (7.16 to 7.20) in all the sampling stations. The Analysis of Variance (ANOVA) showed significance differences (p<0.05) in other parameters across the months. The result showed that air temperature ranged from 32.10±0.73 to 36.15±0.17 oc, water temperature from 30.20±0.94 to 34.30±0.22oc, transparency ranged from 5.9±0.61cm to 18.7±6.17cm, Salinity varied 2.08±0.06 to 3.15±0.50 mg/l. Total dissolved solid (TDS) was between 33.50±7.91 and 83.85±21.06mg/l. Dissolved oxygen (DO) ranged from 6.23±0.05 to 8.28±0.10 mg/l and Electrical conductivity (EC) ranged from 40.00±4.32 to 87.25±19.97ꭒ/s. The parameters were correlated within the stations. The results from the study showed that most of the physicochemical parameters were within the accepted values for consumption, biodiversity, productivity, domestic usage and are below pollution level.

Abstract:

The lack of management practice/silvicultural treatments in the complex tropical mixed forests of Nigeria has led to uncontrolled exploitation of natural forest stands and loss of biodiversity. To sustain production, protection and conservation in the complex tropical mixed stands, this study proposed the application of a selection method – the BDq (B: basal area, D: maximum diameter, q-ratio) method for the management of the stands. Two strata were used as a pilot test: stratum 1 consisted of 15 plots and stratum 2 comprised of 7 plots with a plot area of 0.25 ha. Only trees with diameter at breast (d) ≥ 10.0 cm were considered in this study. Harvest in the BDq method was quantified, by setting B at 20, 25 and 30 m2 ha-1 corresponding to heavy, medium and light-harvesting regimes, respectively. D was set at 65 cm and q-factor was computed for each plot. The results showed that the three BDq regimes (heavy, medium and light) prescribed yielded reasonable felling intensities (FI) derived as the percentage of extracted volume (Vext) and biomass (Wext). The Vext and FI for stratum 1 ranged from 39.94 – 62.30 m3 ha-1 and 11.22 – 18.18 %; and stratum 2 had 30.44 – 51.33 m3 ha-1 and 10.02 – 17.57 %. In the case of biomass, the Wext and FI for stratum 1 ranged from 18.46 – 29.82 tons ha-1 and 9.40 – 15.95 %; stratum 2: 14.16 – 24.82 tons ha-1 and 9.73 – 17.50 %. The finding shows that the application of BDq method to the complex tropical mixed forests in Nigeria would yield an attractive stand.

Abstract:

Abstract Studies have shown that information on landscape transformation is an important benchmark data set because of its value as an environmental change indicator. Therefore, dynamism of landscape transformation over a 34-year period are analysed for a case study in Ibiono-Ibom, Akwa-Ibom State, Nigeria. The study adopted a mixed method consisting of remote sensing and GIS-based analysis, and semi-structured interviews covering 400 households while factors contributing to landscape structures and changes are studied. The results point out three main driving factors responsible for the landscape transformation in the study area: agricultural practices which lead to intensification of forest resources, riparian vegetation, vegetated wetlands and non-vegetated wetlands; urbanization which modifies the structure and morphology of the landscape, and finally, population growth directly related to massive infrastructural development which encroached on all other land spaces. GIS-based analysis of remotely-sensed data showed that built-up area had increased by 7535.2 ha between 1986 and 2020; shrub and arable land by 1343.9 ha and light forest decreased by 4998.3 ha. While bare-land reduced by 1522.1 ha; vegetated wetland reduced by 1092 ha; water body coverage reduced by 168 ha and non-vegetated wetland size also reduced by 2029.4 ha. Analysis of household survey results revealed that the perceptions of respondents validate the observed patterns during the remotely-sensed data analysis phase of the research, with 54 % (n=400) of respondents reporting a decline in agricultural land use, and 19.3 % (n=400) observing a decline in forest areas in the study area. Furthermore, agricultural intensification, urban development, timber exploitation, firewood collection and increase in settlements were identified as the proximate drivers of these observed landscape transformation dynamics in the study area. The study concluded that the variation in landscape transformation of the study area are clear indication of the extent of biodiversity loss and ecosystem degradation in the study area.

Abstract:

The community structure and diversity of land snail fauna in Ekiti State was investigated in two protected and one unprotected tropical rainforest ecosystems. Twelve (12) plots measuring 20m x 20m each were surveyed in each forest area, using direct search and leaf-litter filtering techniques. A total of 1095 specimens representing 43 species in 9 molluscan families were collected. Each forest area yielded between 190 and 584 individuals. Alpha diversity ranged from 27 to 32 species, with species richness highest in Ogbesse Forest Reserve and least in the unprotected forest area at Ipole Iloro. The herbivorous Subulinidae and carnivorous Streptaxidae were the most represented families as regards species richness, with family Subulinidae (45.20%) being the most abundant numerically. The most abundant species was Thapsia oscitan of the family Urocyclidae, contributing almost 15% of the total number of individuals. Six (6) species occurred as singleton while 4 species occurred as doubleton. There was considerable variation in species richness between the three sampled forest areas, Cluster analysis formed two groups, Analysis of similarity (ANOSIM) between clusters using the BrayCurtis similarity index gave values of R=1, P=0.34, indicating that the study areas were well separated. The high diversity and abundance recorded from this study reveal the study area is rich in land snails, thus, efforts should be made to maintain the ecological integrity of the protected areas as well as improve biodiversity conservation and management in the unprotected areas.

Abstract:

Inventory of plant species whose barks were sold in markets located in two local government areas of Kaduna State, Nigeria was carried out in this study. Three markets were selected randomly from each of the two Local Government Areas of the study area. In each market, 10 medicinal plant vendors and 10 respondents were randomly selected and interviewed with the aid of semi structure questionnaire matrix. Plants whose stem barks were of medicinal values were identified; their mode of preparations and utilizations were documented. The respondents were diverse and cut across socioeconomic classification. Respondents’ consciousness was linked to oral transfer of the indigenous knowledge on plants and the recent realization of their economic values thus trading and the act of apprenticing in trading in medicinal plants is now a viable entrepreneurial venture. 54 plant species, belonging to 28 families, have their barks valued for medicine and were sold in the study area. The species were rich in diverse chemical constituents. The sales and patronage of the identified barks, in the study area, transcend gender but skewed to the males due to religious belief thus suggesting that gender specific roles in medicinal plants could be faith-based. Dependence on plant barks was borne out of the age long tradition and confidence of the people on plant medicine. This was complimented by their affordability and ready availability especially in the markets in the study area. Most of the identified barks were sourced outside the study area though forest reserves abound in all parts of the state, yet importation dominated the supply chain as the reserves were highly depleted due to anthropogenic activities. This study tends to support the previous clamour for biodiversity conservation through cultivation of the identified plant species in the study area.

Abstract:

AbstractThe protected area network of Africa has grown from nothing to over 2 million km2 in the past 110 years. This network covers parts of all biomes and priority areas for biodiversity conservation but protected area gaps remain, as identified at the 5th World Parks Congress in 2003. Forest reserves, managed by Forest Departments, are typically excluded from global protected area lists, but in Africa they are found in 23 countries and cover at least 549,788 km2, adding 25% to the conservation estate. Forest reserves protect 5.3% (2,027 km2) of the dry forest habitats, 5% (165,285 km2) of lowland and montane moist forests, 2.6% (364,354 km2) of savannah woodlands, 1.8% (10,561 km2) of flooded grasslands, and 1.65% (1,177 km2) of mangroves. Forest reserves also protect parts of three conservation schemes: 6.5% (61,630 km2) of BirdLife's Endemic Bird Areas, 3.4% (147,718 km2) of Conservation International's Hotpots and 3.4% (346,864 km2) of WWF's Global 200 Ecoregions. Several of the global protected area gaps identified in Africa are also covered by forest reserves, in the Eastern Arc Mountains, Eastern African coastal forests, Kenyan Highlands, Cameroon-Nigerian Mountains, West African Forests and mountain areas of Malawi, Zimbabwe, Mozambique and Zambia. Some African forest reserves have a legally defined role in biodiversity conservation and are strictly protected; they thus fit criteria for protected areas. Working with forest departments in individual countries may help develop a more comprehensive protected area network without creating additional new reserves.

This study investigated the ecology, diversity and seasonal distribution of wild mushrooms at Environmental Pollution Science and Technology (ENPOST) forest reserve, Ilesa, Southwestern Nigeria. Mushrooms growing in the ligneous and terrestrial habitats of the forest were collected, identified and enumerated between March 2014 and March 2015. Diversity indices including species richness, dominance, and species diversity were evaluated. Correlation (p < 0.05) was determined among climatic data and diversity indices. A total of 151 mushroom species specific to their respective habitats were obtained. The highest monthly species richness (70) was obtained in October 2014. While a higher dominance was observed in the terrestrial habitat during the rainy and dry seasons (0.072 and 0.159 respectively), species diversity was higher in the ligneous and terrestrial habitats during the rainy season (3.912 and 3.304 respectively). Overall, the highest carpophores in ligneous and terrestrial habitats were recorded in Schizophyllum commune (10,737) and Mycena monticola (760) correspondingly. Correlation analysis revealed that average monthly precipitation positively correlated with the relative abundance of mushrooms in the terrestrial habitat (r = 0.716, p = 0.013). This study shows the diversity of mushrooms at ENPOST forest, thereby necessitating strict and sustainable conservation measures especially those with great economic values.

Iwaszkiw, Juan, and Francisco Lacoste. ". The aim of this contribution is to consider different issues derived from fish captures from artisanal-commercial fisheries in the Paraná Basin in Argentina. We identify certain impacts related to fishing practices on the involved natural populations and its compromises in ichtiofaunal biodiversity conservation. We consider 17 years of information based on data of fisheries exports for different inland species between 1994-2010. These data includes valuable commercial big sized native fishes like sábalo (Prochilodus lineatus), boga (Leporinus obtusidens), tararira (Hoplias malabaricus), surubí (Pseudoplatystoma spp.), dorado (Salminus brasiliensis) and patí (Luciopimelodus pati), together with several catfish species and minor species as silversides. Freshwater fish exports show a major rise resulting in 331517 ton for these years. The target species is sábalo (88.77 %), other accompanying species are tararira (4.16 %), boga (3.7 %) and Patí (1.35 %) whereas the remainig catches belong to other species. There is a strong rise in the catches of these other species in certain years while there is not a clear legislation for these fish species that allow implementing a proper fishery management along the basin. The importing countries are Brazil, Colombia, Bolivia and Nigeria among others. Since 2003 Colombia buy an average of 50% of inland fisheries exports from Argentina. The analysis historical data (1994-2010) reveals the need to implement measures to control and management of fisheries and its effects on fish biodiversity conservation in the basin."

Abstract:

The use of agro-biodiversity practices are key coping strategies in adapting to climate change. This study determined the level of use of Agro- biodiversity conservation practices, assessed the benefits of the practice and identified constraints to its use. A three- stage sampling technique was used to select 150 respondents on which a structured interview schedule was administered. Descriptive statistics and Pearson’s Product Moment Correlation were used for data analysis. Results shows that the use of animal dungs and plant residues as bio-fertilizers was common biodiversity practice among farmers. 82.5% of the farmers were in the low level of use of these practices. Constraints such as high cost of production lack of awareness of the use of these practices, were major constraints to the use of biodiversity practices. Age, years of schooling years of farming experience were significantly related to level of usage of Agro biodiversity practices. The study concludes that the level of use of Agro biodiversity practices among farmers was low and influenced by socioeconomic characteristics of the farmers. It recommends that government and other stake holders should provide necessary facilities for this practice. Extension agents should also sensitive farmers on the usefulness of Agro-biodiversity.

Abstract:

The West African country Nigeria features highly diverse vegetation and climatic conditions that range from rain forest bordering the Atlantic Ocean in the South to the Desert (Sahara) at the Northern extreme. Based on data from the World Conservation Monitoring Center of the United Nations Environmental Protection, Nigeria, with ~5,000 documented vascular plants, ranks amongst the top 50 countries in terms of biodiversity. Such a rich biodiversity implies that the country is rich in diverse secondary metabolites—natural products/unique chemicals produced by the plant kingdom to confer selective advantages to them. Like many tropical countries, Nigeria is also endemic to numerous infectious diseases particularly those caused by parasitic pathogens. These phytochemicals have been exploited for the treatment of diseases and as a result, a new branch of chemistry, natural product chemistry, has evolved, to try to reproduce and improve the therapeutic qualities of particular phytochemicals. In this review, we have compiled a compendium of natural products, isolated from Nigerian flora, that have been reported to be effective against certain protozoan parasites with the aim that it will stimulate interests for further investigations, and give impetus to the development of the natural products into registered drugs. In total 93 structurally characterized natural compounds have been identified with various levels of anti-parasite activity mainly from Nigerian plants. The synthesis protocol and molecular target for some of these natural anti-parasite agents have been established. For instance, the anti-plasmodial compound fagaronine (7), a benzophenanthridine alkaloid from Fagara zanthoxyloides has been successfully synthesized in the laboratory, and the anti-trypanosomal compound azaanthraquinone (55) elicits its effect by inhibiting mitochondrial electron transfer in trypanosomes. This review also discusses the barriers to developing approved drugs from phytochemicals, and the steps that should be taken in order to accelerate the development of new antiparasitics from the highlighted compounds.

Abstract:

Abstract Africa plays a central importance role in the human origins, and disease susceptibility, agriculture and biodiversity conservation. Nigeria as the most populous and most diverse country in Africa, owing to its 250 ethnic groups and over 500 different native languages is imperative to any global genomic initiative. The newly inaugurated Nigerian Bioinformatics and Genomics Network (NBGN) becomes necessary to facilitate research collaborative activities and foster opportunities for skills’ development amongst Nigerian bioinformatics and genomics investigators. NBGN aims to advance and sustain the fields of genomics and bioinformatics in Nigeria by serving as a vehicle to foster collaboration, provision of new opportunities for interactions between various interdisciplinary subfields of genomics, computational biology and bioinformatics as this will provide opportunities for early career researchers. To provide the foundation for sustainable collaborations, the network organises conferences, workshops, trainings and create opportunities for collaborative research studies and internships, recognise excellence, openly share information and create opportunities for more Nigerians to develop the necessary skills to exceed in genomics and bioinformatics. NBGN currently has attracted more than 650 members around the world. Research collaborations between Nigeria, Africa and the West will grow and all stakeholders, including funding partners, African scientists, researchers across the globe, physicians and patients will be the eventual winners. The exponential membership growth and diversity of research interests of NBGN just within weeks of its establishment and the unanticipated attendance of its activities suggest the significant importance of the network to bioinformatics and genomics research in Nigeria.

Abstract:

Background: The loss of biodiversity in Nigeria is escalating alarmingly. However, there is generally a paucity of information as to what taxa are endangered because of a dearth of functioning conservation agencies in Nigeria.Objectives: The aim of this research is to record the endangered medicinal and other economic plant species in the Sudan Savanna vegetation in Katsina and to provide an assessment of the various threats faced by these plants.Method: Medicinal plants were identified through oral interviews with traditional medical practitioners within the study area. Conservation statuses were assessed using a bespoke data collection and assessment form; the data were then evaluated using the International Union for the Conservation of Nature Red List categories and criteria.Results: A total of 169 species belonging to 62 families were recorded. Of these, 43 taxa were reported to be used for ethnomedicinal practices. It was found that more than half (108) of the 169 species were threatened with extinction and one taxon (Xeroderris stuhlmannii [Taub.] Mendonca Sousa) qualifies as being Extinct locally. Threats recorded include overexploitation (24%), agriculture (15%), deforestation and desertification (12% each), invasive plants (11%), urban residential development (7%) and erosion (6%).Conclusion: Most of the plants are already under threat and require urgent conservation measures. The data point to the critical need for further research into conservation strategies and a more sustainable use of threatened plants. We recommend that the Nigerian government should establish a national Red List agency and ensure effective protected area management and community-based natural resources management.
