Habitat reconstruction is commonly employed to restore degraded estuarine habitats and lost ecological functions. In this study, we use a combination of stable isotope analyses and macrofauna community analysis to compare the ecological structure and function between a recently constructed Spartina alterniflora salt marsh and a natural reference habitat over a 2-year period. The restored marsh ...
Food-storing birds, for example, marsh tits, Parus palustris, use memory to retrieve stored food and have a larger hippocampus relative to the rest of the telencephalon than do species that store little or no food such as the blue tit, P. caeruleus. The difference between food storers and nonstorers in relative hippocampal volume occurs after the young birds have fledged from the nest and is de...
Halomorphic soils cover a significant area in the Vojvodina region and represent ecological economic challenges for agricultural forestry sectors. In this study, four economically important Serbian poplar clones were compared according to their biochemical transcriptomic responses towards mild severe salt stress select most tolerant afforestation of halomorphic soils. Three prospective Populus ...
در این تحقیق ویژگیهای تخته خرده چوب ساخته شده از چوبهای تولیدی 17 کلن صنوبر در دوره بهره برداری کوتاه مدت دو ساله مورد بررسی قرار گرفته است. از هر کلن (تیمار) سه تخته (در مجموع 51 تخته) با استفاده از چسب اوره – فرم آلدیید در شرایط یکسان ساخته شده، خصوصیات فیزیکی و مکانیکی آنها اندازه گیری و در قالب طرح آزمایشی فاکتوریل کاملا تصادفی متعادل با یک متغیر و با استفاده از آزمون دانکن (DMRT) مورد مقای...
aim : to assess the clinical characteristic of cd as well as correlation of symptoms and the degrees of intestinal mucosal lesions in iranian children. background : microscopic enteritis (marsh 0-ii) is associated with malabsorption. patients and methods : from august 2005 to september 2009, 111 cases with malabsorption and classical gastrointestinal symptoms were evaluated. results : the mean ...
background: celiac disease (cd) has been found in up to 10% of the patients presenting with unexplained abnormal liver function tests (lft). as there is no precise data from our country in this regard, we investigated the prevalence of cd in patients presenting with abnormal lft. methods: from 2003 to 2008, we measured iga anti-tissue transglutaminase (t-tg) antibody (with elisa technique) with...
Salt marsh ecosystems have been considered not susceptible to nitrogen overloading because early studies suggested that salt marshes adsorbed excess nutrients in plant growth. However, the possible effect of nutrient loading on species composition, and the combined effects of nutrients and altered species composition on structure and function, was largely ignored. Failure to understand interact...
Studies were conducted to determine the effects of spent reagent from air pollution control scrubbers used at a brick manufacturing facility on emergence, growth, and physiological responses of corn and hybrid poplar plants. Scrubber by-product was obtained from General Shale Brick, Louisville, KY. Potting substrate was weighed and quantities of scrubber by-product were added to the substrate t...
Background Domain of Unknown Function 231-containing proteins (DUF231) are plant specific and their function is largely unknown. Studies in the model plants Arabidopsis and rice suggested that some DUF231 proteins act in the process of O-acetyl substitution of hemicellulose and esterification of pectin. However, little is known about the function of DUF231 proteins in woody plant species. Res...
