EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Morphometric Relationship and Condition Factors of Four Cichlids from Golinga Reservoir in Northern Region of GhanaElliot Haruna Alhassan, Daniel Nsoh Akongyuure, Francis AsumangLength-weight relationship and condition factor have severalapplications on fish biology, physiology, ecology and fisheries assessment. A six-month study was conducted from November 2013 to April 2014 to determine the length-weight relationship and condition factor of four major cichlids namely Oreochromis niloticus (Nile tilapia), Hemichromis fasciatus (Banded jewelfish), Sarotherodon galilaeus (Mango fish) and Tilapiazillii (Red-belly tilapia) to fill a knowledge gap … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 15 Aug 2015 · 8,203 accessesView PDFCite

This study in mangrove swamps was carried out in order to know if social wasp, Mischocyttarus (Mischocyttarus) rotundicollis could be attracted by fish (sardine) in decomposition. The insects were collected in mangrove swamps in Itaborai, every two weeks, totaling 72 samples from … …OnLine Journal of Biological Sciences, Vol. 13, Issue 4 · 7 Dec 2013 · 7,048 accessesView PDFCite
Research ArticleOpen accessIn the abstractRestoration of Biodiversity and EcosystemIgnacio Santa-Regina, M. C. Santa-ReginaSuccession is one of the most studied processes in ecology and succession theory provides strong predictability. However, few attempts have been made to influence the course of succession thereby testing the hypothesis that the passage of one stage is essential to enter a next one. At each stage of succession ecosystem processes may be affected by the diversity of species … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 10 Mar 2013 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Atmospheric Turbidity and its Correlation with Climatologically ParametersU. Ali Rahoma, A. H. HassanStudy of Atmospheric turbidity is important for purposes of meteorology, ecology, climatology and monitoring of atmospheric pollution. Linke Turbidity factor (LT) is commonly used to model the attenuation of solar radiation in the atmosphere. The probable dependence on the water vapor content of the relationship linking LT to Angstrom’s turbidity coefficient B, is discussed. In this study, a procedure for … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractMercury in Hair of Muskox on the Seward PeninsulaClaudia Ihl, R. Terry Bowyer, Kriya L. Dunlap, Lawrence K. DuffyProblem statement: Muskoxen (Ovibus moschatus) are distant relatives of sheep (Caprinae) and have roamed the Arctic for a million years, with populations reaching North America between 150,000 and 250,000 years ago. Muskox populations could be negatively influenced by climate change and increased exposure to contaminants. Since the snow depth is a critical factor in their ecology, effects could occur throughout … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 24 Mar 2012 · 7,008 accessesView PDFCite
