Shifting effects of physiological integration on performance of a clonal plant during submergence and de-submergence.
BACKGROUND AND AIMS Submergence and de-submergence are common phenomena encountered by riparian plants due to water level fluctuations, but little is known about the role of physiological integration in clonal plants (resource sharing between interconnected ramets) in their adaptation to such events. Using Alternanthera philoxeroides (alligator weed) as an example, this study tested the hypothe...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولToxinology of Venomous Marine Worms; A Review
Although the widespread distribution of venomous marine worms around the world, the structural and toxinologcal studies of their toxins are still limited.This study was aimed to evaluate the toxicity of poisonous marine worms. Touching the cilium of Chloeia flava and Sipuncula marine worms cause painful inflammation of the skin. Many species of nemertines prey their victims by a flexible prob...
متن کاملPhysical transport properties of marine microplastic pollution
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Given the complexity of quantitative collection, knowledge of the distribution of mi-croplastic pollution in many regions of the world ocean is patchy, both spatially and temporally, especially for the subsurfac...
متن کاملAssembly of a Marine Viral Metagenome after Physical Fractionation
Metagenomic analyses of marine viruses generate an overview of viral genes present in a sample, but the percentage of the resulting sequence fragments that can be reassembled is low and the phenotype of the virus from which a given sequence derives is usually unknown. In this study, we employed physical fractionation to characterize the morphological and genomic traits of a subset of uncultivat...
