The review was conducted to Phenotypic Characterization and breeding practice of Indigenous Chicken Populations in Ethiopia. Concerned with breeding practice of producers of indigenous chicken were practiced for improved their chicken productivity through cross breeding and pure breeding methods. Indigenous chickens don’t have phenotypic standards and their classification is given based on colours and name of place where they are characterized. Still those local chickens are non-descriptive type and show variations in body position, plumage colour, comb type, their adaptation and productivity. Scavenging production systems is the dominant management practices of chicken with small feed supplementation. High incidence of chicken diseases, mainly (NCD) is the major economically important constraints for village chicken production systems followed by feed shortage and predators in the country. Since local chickens have good potential to adapt in different agro-ecology and make available well-appointed source of family protein and income for rural people. Indigenous breeds of chickens are playing an important role in rural economies in most of the developing countries. They play a major role for the rural poor people with respect to their subsidiary income and provide them with nutritious of chicken egg and meat for their own consumption. The present review was made to document the importance of indigenous chicken characterizations and breeding Practices in Ethiopia for rural economy and its improvement with respect to performance.

Ethiopia has largest livestock population in Africa. Despite the largest cattle population, its productive and reproductive performance is very low productivity is relationship between inputs and outputs. The information about reproductive and productive performance in Ethiopia is limited for smallholder. Therefore; the objective of this review paper was to highlight the overall aspects of reproductive and productive performance parameters under Ethiopian condition. Reproductive performance is a trait of outstanding importance in dairy cow enterprises. The production of milk depends heavily on reproductive activity. Reproductive performance traits include number of service per-conception (NSC), calving interval (CI) and days open (DO). Productive performance traits include lactation length (LL), lactation yield (LY) and daily milk yield (DMY) are important criteria for profitable dairy farming. In Ethiopia, crossbred dairy cattle mainly are crosses of zebu with Holstein-Friesian and the mean reproductive performance like CI and productive performance like LL were near to the optimum. The mean values of reproductive and productive traits lower in case of indigenous breed than Friesian and their crosses. However, information is limited about the reproductive and productive performance of dairy cows in smallholder, urban and peri-urban dairy farms in the tropics, particularly in Ethiopia. With efficient management of cows, it is possible to improve performance traits. It is concluded that by improving genetic makeup of dairy cow it is possible to improve the reproductive and productive performance of dairy cattle in Ethiopia.

Heavy metal removal from waste water is essential to solve the global water crises. Transition metal oxide nanoparticles are promising candidates for these applications. Herein, Copper oxide and Tin oxide nanoparticles have been prepared via Facile and economic perception method starting from commercial precursors. The obtained nanoparticles were in flack-like shape and spherical shape for Copper oxide and Tin oxide nanoparticles, respectively. All prepared nanoparticles are in crystalline phases, where the prepared Copper oxide and Tin oxide nanoparticles were in monoclinic and tetragonal crystalline phases, respectively. The crystal size of Copper oxide and Tin oxide nanoparticles were 12 nm and 13 nm respectively. Cd and Pb ions were removed from wastewater by the obtained Copper oxide and Tin oxide nanoparticles. The adsorption processes were studied under various parameters, such as; contact time and pH values. The highest removal uptake was about ~99% of Pb ions were recorded for Copper oxide nanoparticles. This uptake process carried out after 30 min in a neutral medium (pH 7). While, Tin oxide nanoparticles removed about ~94% at the same conditions. On the other hand, Copper oxide nanoparticles removed about ~ 57% from Cd ions. This uptake process carried out after 30 min in a partially acidic medium (pH 6). While, Tin oxide nanoparticles removed about ~54% at the same conditions. Finally, it is highly recommended to use Copper oxide and Tin oxide nanoparticles as promising adsorbents for heavy metal removal applications.

Bisphenol A (BPA) is an environmental endocrine disruptor and has been strongly associated with the development of numerous diseases, including ovarian follicle development disorders. BPA is being replaced by structurally similar chemicals, such as bisphenol S (BPS), bisphenol F (BPF) and bisphenol AF (BPAF). However, the toxicity of these analogues in female reproduction is unclear. Here, we investigated the induction of cytotoxicity and mitochondrial dysfunction in the human granulosa cell line KGN by BPA and its selected analogues. We found that BPA and its analogues, especially BPAF, significantly reduced cell viability and caused cytotoxicity. Furthermore, we observed that BPA and BPAF significantly reduced mitochondrial function, including decreasing ATP generation, promoting ROS production and increasing intracellular Ca2+ levels. An oxidative-antioxidant imbalance was also detected after exposure to these chemicals. In contrast, the total antioxidant capacity was significantly reduced. To our knowledge, this is the first report on the evaluation of the potential of BPA and its analogues to induce cytotoxicity and mitochondrial dysfunction in ovarian granulosa cells. Our study revealed the possible mechanism of BPA and its analogues inducing granulosa cell damage and suggested that mitochondrial dysfunction may play an important regulatory role in bisphenol-induced follicular development disorders.

Small Scale Irrigation plays a substantial role in advancing agriculture by increasing productivity and enhancing household food security. The Objective of the study is to see factors affecting resettled farmers' participation decisions in Small scale irrigation and to analyze the impacts of small scale irrigation on household food security. The study used cross-sectional data with a multistage stage sampling technique of 262 and 77 non-irrigation and irrigation user resettled households were interviewed. Binary probit models, Heckman sample selection model two-step is employed in the analysis of the study. The study showed that resettled households with a strong perception on land productivity utilize modern agricultural input, more perception on soil fertility, more access of extension service and with the previous landholding on the site selected for irrigation have more likelihood of participation decision in small scale irrigation than that household with less access and perceptions. Contrary to that resettled households of large land Size holding, more perception on irrigation land repossession and more awareness on irrigation regulation are found to have less likelihood of participation decision in small-scale irrigation. The ordinary least square using adult Equivalent expenditure on food as outcome variable revealed that as Age of resettled households, distance from the market, tropical livestock holding, and crop diversification increases the resettle household food security increases. While Awareness of households on irrigation regulation & modern farm input utilization was found to harm resettled household food security. As per the study finding holding large land size, less awareness on irrigation regulation, and fear of repossession of irrigation land in case of defaulted farming are found to be the challenging factors to influence resettled household participation decision in small scale irrigation and while as the farmers adopt more input on rain-fed land and develop less awareness on irrigation regulation coping capacity to food security was challenged. This is due to farming input cost escalation, soil fertility deterioration, and poor land preparation, acidisty of the soil due to heavy rain fall and poor crop management practices and hesitation for land reposition incase of irrigation land preparation default. The study recommended a concerned body and stockholders to revisit irrigation regulation for amendment, soil, and water conservation practice to be taken as an intervention package and further study to exceed the scope of the study.

Mercury (Hg) pollution is featuring as one of the major threat for marine ecosystem, biota and human health. Thereby, the objective of the current study was to evaluate the effect of environmentally relevant concentrations of mercury on oxidative stress, enzymatic and non-enzymatic antioxidant defenses and metallothionein levels in the longitudinal muscle of sea cucumber Holothuria forskali. With this purpose, sea cucumber were exposed to graded concentrations of mercury chloride HgCl2 (40, 80 and 160 µg L-1) for 96 h under controlled conditions. Our findings revealed that Hg burden in the longitudinal muscle tended to increase with increasing HgCl2 concentrations. The Hg exposure promoted muscular oxidative stress as evidenced by the increased levels of malondialdehyde (MDA), advanced oxidation protein product (AOPP) and metallothionein (MT) of treated animals compared with controls. Additionally, significant increases in the activities of the enzymatic (glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT)) and non-enzymatic (non-protein thiol (NPSH) and glutathione (GSH)) antioxidants were also observed in all treated groups. Overall, this study proved that mercury is able to produce deleterious effects even at the lowest environmentally-realistic concentration in the Holothuria forskali longitudinal muscle which may be considered as a target tissue of mercury accumulation in holothurian.

The earthworms (Eiseniafetida) were collected from Adami Tulu Agricultural Research Centerand introduced in cattle manure, paunch manure and cattle manure supplemented with wheat sraw, paunche manuresupplemented with wheat sraw and cattle manure plus paunch manure supplemented with wheat sraw.300 numbers of red worms (Eisenia fetida) were introduced in to each treatment. At the end of vermicomposting, the earthworm populationand vermicompost amounts were examined to assess the effect of feeding materials on multiplication of worms (Eisenia fetida), vermicompost yield and vermicompost qualities. The highest numberof worms (688.3) was achieved in the paunch manureand lowest (333.7) in the cattle manure vermicompost as sole source of feeding material as compared to all treatments. But the amount of vermicompost was found to be highest (9.6 kg) in mixture of paunch manure and wheat straw vermicompost. The vermicompost samples were analyzed for the parameters: pH, EC, total nitrogen, organic carbon, available phosphorus. The laboratory analysis results showed highest total nitrogen (3.03%), organic carbon (31.04%), andavailable phosphorus (1523 mg/kg) were recorded in case of vermicompost prepared paunch manure alone. The C:N ratio of all vermicompost samples was in the optimum range (< 20%) and the EC of vermicompost prepared from paunch manure was in the optimum range and the rest were above the optimum rangeof EC values for plants growth. However, the bedding materials give different results and have their own characteristic on selected physic-chemical parameters, all the vermicompost samples were contains sufficient amount of plant nutrients and optimum pH for the better seed germination, plant growth and best fertility and quality of soil. Therefore, all the vermicompost samples could be used as organic fertilizer in agriculture. But based on its highest number of red worms (Eiseniafetida), highestyield of vermicompost and highest total nitrogen contents, organic carbon andavailable phosphorus, vermicompost prepared from paunch manure as sole source of feeding material was considered as quality vermicompost.

This study was conducted with objective to determine extent of phenotypic diversity in Arabica coffee accessions from Eastern Ethiopia. Treatments consisted of 49 coffee accessions. The accessions were field planted at Mechara Agricultural Research Center in July, 2005 using simple lattice design with two replications. Total of 15 quantitative characters were recorded using standard coffee descriptors. The collected data were subjected to SAS software for Analysis of variance. Cluster analysis was also done. Mean squares due to coffee accessions were highly significant (p<1%) for all quantitative characters studied except for number of internodes of main stem and average length of primary branch, indicating the presence of remarkable phenotypic variation among the coffee accessions studied. For stem characters, plant height varied from 94.00 to 165.40 cm; number of internodes of main stem ranged from 17.90 to 24.80 cm; internode length of main stem varied from 5.30 to 8.25 cm; diameter of main stem from 3.40 to 5.35 cm. For branch characters, number of primary branches ranged from 30.20 to 43.10; length of primary branch from 43.10 to 105.10 cm; numbers of internodes of primary branch 14 to 26.70; internode length of primary branch was from 3.20 to 5.73 cm; numbers of secondary branch varied from 41.10 to 133.20. For leaf characters, leaf length varied from 9.20 cm to 18.43 cm and with mean of 13.40 cm. Leaf width from 3.49 to 8.77 cm with mean vale of 6.24 cm. Average leaf area of all accessions was 57.96 with variation from 24.63 to 105.45 cm 2. Weight of hundred beans ranged from 11 g for five accessions (H-25/04, H-40/04, H-41/04 and H-618/ 98) to 16.5 for H03/04 with mean value of 13.53 g. Cluster analysis grouped the coffee accessions into five groups of different sizes, ranging from one entry in cluster IV and V to 34 in cluster I. Inter-cluster distances were highly significant (p=0.01) except between cluster I and II, indicating presence of considerable phenotypic diversity in coffee accessions from eastern Ethiopia. It is advisable to maintain and evaluate the coffee genotypes for disease resistance, moisture stress tolerance, yield and cup quality in future studies.

Total of 15 quantitative characters were recorded using standard coffee descriptors. The collected data were subjected to SAS software for Analysis of variance. Cluster analysis was also done. Mean squares due to coffee accessions were highly significant (p<1%) for all quantitative characters studied except for number of internodes of main stem and average length of primary branch, indicating the presence of remarkable phenotypic variation among the coffee accessions studied. For stem characters, plant height varied from 94.00 to 165.40 cm; number of internodes of main stem ranged from 17.90 to 24.80 cm; internode length of main stem varied from 5.30 to 8.25 cm; diameter of main stem from 3.40 to 5.35 cm. For branch characters, number of primary branches ranged from 30.20 to 43.10; length of primary branch from 43.10 to 105.10 cm; numbers of internodes of primary branch 14 to 26.70; internode length of primary branch was from 3.20 to 5.73 cm; numbers of secondary branch varied from 41.10 to 133.20. For leaf characters, leaf length varied from 9.20 cm to 18.43 cm and with mean of 13.40 cm. Leaf width from 3.49 to 8.77 cm with mean vale of 6.24 cm. Average leaf area of all accessions was 57.96 with variation from 24.63 to 105.45 cm 2. Weight of hundred beans ranged from 11 g for five accessions (H-25/04, H-40/04, H-41/04 and H-618/ 98) to 16.5 for H03/04 with mean value of 13.53 g. Cluster analysis grouped the coffee accessions into five groups of different sizes, ranging from one entry in cluster IV and V to 34 in cluster I. Inter-cluster distances were highly significant (p=0.01) except between cluster I and II, indicating presence of considerable phenotypic diversity in coffee accessions from eastern Ethiopia. It is advisable to maintain and evaluate the coffee genotypes for disease resistance, moisture stress tolerance, yield and cup quality in future studies.","PeriodicalId":161728,"journal":{"name":"International Journal of Ecotoxicology and Ecobiology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130344580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The threat to humans, animals, and plants life by pollution due to gas flare and oil and gas industrial activities cannot be overemphasized. This study compared the hydrocarbons and heavy metals accumulation in cassava tubers harvested from four different locations in Rivers State. The study areas include Rukpoku, Rivers State University (RSU) farm, Eleme community and Nkpolu-Oroworukwo community. Cassava tubers were collected from farms located in the aforementioned areas, prepared and analyzed for hydrocarbons and heavy metals contents. Standard spectro-analytical method was used to determine the concentrations of zinc (Zn), iron (Fe), lead (Pb), copper (Cu) and manganese (Mn), while polycyclic aromatic hydrocarbons (PAHs), total polycyclic hydrocarbon (TPH) and BTEX (benzene, toluene, ethyl benzene, xylene) were analyzed using standard chromatographic procedure. Results obtained from the analyses revealed the presence of heavy metals in all the samples in the order Eleme > Nkpolu-Oroworukwo > Rukpoku > RSU farm. Pb was not detected in the entire sample analyzed, Mn was below the permissible range, while Zn, Fe and Cu were above the permissible range. TPH was detected in all samples analyzed in the order Eleme > Nkpolu-Oroworukwo > Rukpoku > RSU farm. RSU farm had the least concentration of PAH, While BTEX was not detected in all samples analyzed. The results suggest the presence of heavy metals and hydrocarbons (anthracene, acenaphthene, phenanthrene, fluoranthene, pyrene, benz (a) anthracene, benz (b) fluoranthene, indeno (1,2,3-cd) pyrene, dibenz (a, h) anthracene) in cassava tubers harvested from the study locations, but with greatest accumulation in samples from Eleme community and least in those from RSU farm. Consumption of such crops could pose health challenges to the consumers over time.

Anthropogenic activities on the environment have intensified in the last century resulting in a devastating increase in greenhouse gases and triggering global climate oscillation. Global food productions have increase significantly by 50% in order to meet the anticipated demand of the world’s population by 2050. The challenges of food production increases are high and even harder if climate change as a global threat is not addressed. In the coming years, there could be more changes in the biosecurity of food crops due to escalating global climate change. The effects of climate change on plant pathogens and the diseases they cause have been reported in some pathosystems. Climatic changes have been predicted to affect pathogen development and survival rates with possible modification of host susceptibility, host-pathogen-vector interaction that could lead to changes in the impact of diseases on food crops. The climate change may affect not only the optimal conditions for infection but also host specificity and mechanisms of plant infection. Changes in the abiotic conditions are known to affect the microclimate surrounding plants and the susceptibility of plants to disease. These changing conditions are expected to affect microbial communities in the soil and canopy pathosystems, with the possibility of altering the beneficial effects of these communities. Since both the pathogens and host plants could be affected by the dramatic changes in the magnitude of disease expression in a given pathosystem, the geographical distribution of particular plant diseases, their economic importance in a given location, and the set of diseases that infect each crop are crucial to understand their etiology and level of virulence. These changes could affect the measures farmers take to efficiently manage these diseases, as well as the feasibility of cropping systems in particular regions. This review examines the effects of changes in temperature, CO2 and ozone concentrations, precipitation, and drought on the biology of pathogens and their ability to infect plants and survival in natural and agricultural environments. We also underpin the multiple aspects linked to the effects of climate change on crop plant diseases, including the impact of increasing concentrations of atmospheric CO2 and other gases, and how diseases can change under the alteration of atmospheric gases conditions in the future.
