Research ArticleOpen accessIn the abstractUnder WaterRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella, Florian Ion Tiberiu PetrescuWith a 361 million square Km surface and a volume of 1370 million of cubic kilo, world seas and oceans have represented and still remain the privileged space for living species evolution. Other than being the 70% of the Earth surface, water environment, contrary to the terrestrial one where life essentially develops in 2 dimensions, is a 3D fully volume … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 10 Jun 2017 · 7,235 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite

In particular, we touch upon the impact of climate change on water resources, agriculture, ecosystems, etc. and propose measures to minimize, prevent and reduce economic losses from the lack of water resources, … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 13 May 2016 · 7,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cement Dust on the Physiological Activities of Arabidopsis thalianaSaeid Abu-Romman, Jarrah AlzubiAir pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation, lipid per oxidation … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 17 Nov 2015 · 8,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Land Cover on Streamflow Variability in a Small Iowa Watershed: Assessing Future VulnerabilitiesKeith Schilling, Matthew Streeter, Kasey Hutchinson et al.Agricultural expansion and urbanization, coupled with climate change represent major threats to the sustainability of river ecosystems and infrastructure. In this study, we evaluated how subbasins with different dominant land covers within the 27.5 km2 Clear Creek, IA watershed affect key hydrologic indicators. Hydrologic output from two stream gages and a calibrated Soil Water Assessment Tool (SWAT) model were used … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 6 Jul 2015 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the abstractACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,455 accessesView PDFCite
