Research ArticleOpen accessEvery word in the titleUpdates on Nutritional Diversity in Sphenostylis stenocarpa (Hoechst ex. A. Rich.) Harms. for Food Security and ConservationCatherine Veronica Nnamani, Sunday Adesola Ajayi, Happiness Ogba Oselebe et al.Neglected and underutilized plant genetic resources constitute opportunity for diversification of food and environmental services globally, particularly within communities in developing country. They can provide, in some cases, higher nutrient content than traditional globally accepted staples commonly consumed. Currently, with climate uncertainty and the desire and challenge for sustainably produced food, there is an urgent need to promote crop diversity. … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 10 Jul 2018 · 9,336 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDiversity and Allelopathic Potential of Weeds among Panamanian Coffee CropsLilia Cherigo, Jorge Lezcano, Sergio Martínez-LuisWorldwide, coffee is one of the most highly consumed and produced crops. Coffee production is a significant activity in the Panamanian economy, mainly in rural communities and among indigenous groups in the Chiriquí province highlands. Weeds growing alongside coffee plants can provoke considerable economic losses for producers by interfering with the growth, development and yield of coffee crop in cultivated … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 6 Sep 2017 · 7,465 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleASSESSING THE EFFECTS OF LOGGING ACTIVITIES ON AVIAN RICHNESS AND DIVERSITY IN DIFFERENT AGED POST-HARVESTED HILL DIPTEROCARP TROPICAL RAINFOREST OF MALAYSIAM. N. Rajpar, M. ZakariaLogging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Jul 2014 · 7,580 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGENETIC DIVERSITY OF OKRA (ABELMOSCHUS ESCULENTUS L.) GENOTYPES FROM DIFFERENT AGRO-ECOLOGICAL REGIONS REVEALED BY AMPLIFIED FRAGMENT LENGTH POLYMORPHISM ANALYSISNaser M. SalamehThis study was carried out to assess the genetic diversity in 48 genotypes and accessions using eight Amplified Fragment Length Polymorphism (AFLP) primer-pairs. The eight selected AFLP primer-pairs generated a total of 150 polymorphic loci. Using the generated AFLP data, the Un-Weighted Pair Group Method with Arithmetic Average (UPGMA) ordered the genotypes into six groups based on Dice similarity coefficient. … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 29 Apr 2014 · 8,069 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleToward a Hierarchical Bayesian Framework for Modelling the Effect of Regional Diversity on Household ExpenditurePudji Ismartini, Nur Iriawan, Setiawan, Brodjol Sutijo Supri UlamaProblem statement: Household expenditure analysis was highly demanding for government in order to formulate its policy. Since household data was viewed as hierarchical structure with household nested in its regional residence which varies inter region, the contextual welfare analysis was needed. This study proposed to develop a hierarchical model for estimating household expenditure in an attempt to measure the effect … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 25 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Diversity of Some Saudi Barley (Hordeum Vulgare L.) Landraces Based on Two Types of Molecular MarkersMohamed Abdel Hamid Mohamed El-Awady, Adel Ahmed El-Sayed El-Tarras, Salah El-Din El-AssalProblem statement: Very little is known about the genetic diversity and morphological variability present in barley landrace in KSA, a country experiencing loss of biodiversity because of replacement of landraces with modern landraces. Approach: The molecular markers RAPD and ISSR were used as an efficient tools to estimate the intra-and inter-cultivar polymorphism among six barley KSA landraces collected from different … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,502 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDiscrimination Capacity of RAPD, ISSR and SSR Markers and of their Effectiveness in Establishing Genetic Relationship and Diversity among Egyptian and Saudi Wheat CultivarsSalah El-Din El-Assal, Ahmed GaberProblem statement: Yield crop cultivars and landraces are valuable sources of genetic variations that the knowledge and implication of these variations are critical in the plant breeding programs. our major objective of this study is investigating the discriminating capacity of RAPD, ISSR and SSR markers and of their effectiveness in establishing genetic relationship and diversity among Egyptian and Saudi wheat … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 9 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Diversity in Cichla monoculus (Spix and Agassiz, 1931) Populations: Implications for Management and ConservationCarlos Henrique Dos Anjos Dos Santos, Carolina Fernandes Silva De Sousa, Maria de Nazare Paula-Silva et al.Problem statement: The object of this study was to examine the genetic structure and gene flow in Cichla monoculus populations in seven varzea lakes of the Solimoes River using Randomly Amplified Polymorphic DNA (RAPD) markers, to monitor the region where petroleum is transported in the Amazon basin. Approach: The loss of genetic diversity is one of the main factors leading … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 30 Jan 2012 · 8,517 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Genetic Diversity among Sugarcane Cultivars (Saccharum officinarum L.) using Simple Sequence Repeats MarkersAshutosh Pandey, Rupesh K. Mishra, Shashank Mishra et al.Problem statement: Increasing sugar productivity is the main concern of sugarcane (Saccharum officinarum L.) breeding programs. The complexity and size of the sugarcane genome is a major limitation in its genetic improvement. Characterization of sugarcane provides essential information of genetic diversity for breeders utilize for crop improvement. Approach and Results: The objective of this study was to evaluate the microsatellite … …OnLine Journal of Biological Sciences, Vol. 11, Issue 4 · 27 Jan 2012 · 7,563 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDiversity of the Rhizosphere Soil Culture-Dependent Fungi of Mature TobaccoXiaolin Li, Xinzhu Li, Kewei Zhao et al.Problem statement: The maturation of tobacco is a very important period of tobacco production. Until recently, there are no many reports on tobacco rhizospheric culturable fungi, especially at the mature stage. Approach: Five rhizosphere soils of tobacco and five non-rhizosphere soils of tobacco were collected in Yanbian county, Panzhihua.
