Abstract Three-dimensional excitation–emission matrix fluorescence spectroscopy coupled with parallel factor analysis was adopted to investigate the characteristics of dissolved organic matter (DOM) components in water samples collected from Tuojiang River Basin Chengdu, including its main stream and tributaries. Four DOM that matched three peaks were identified whole river basin tributaries; w...

Known as pantun to the Malays in Brunei, Malaysia, Pattani, Riau, Singapore, and Southern Phillipines, it is called peparikan to the Javanese, sesindiran to the Sundanese and many other different names in different ethnic groups in the different parts of the Indo-Malay world, which is made up of Brunei, Indonesia, Malaysia, Singapore, Pattani in southern Thailand, and Mindanao in the southern P...

— Motivated by a particular interest in the distribution of the nonindigenous, piscivorous Sacramento pikeminnow Ptychocheilus grandis, we examined fish–habitat relationships in small tributaries (draining 20–200 km2) in the Eel River drainage of northwestern California. We sampled juvenile and adult fish in 15 tributaries in both the summer and fall of 1995 and attempted to relate the densitie...

Our study of the Seti River in far western Nepal shows that the solute chemistry of the river and its tributaries is strongly controlled by geology. The Seti flows through four distinct terranes, starting with the Tethyan sedimentary series (TSS) and Greater Himalayan series (GHS). TSS/GHS waters display Sr/Sr ratios of ,0.73 and high Sr and Ca, consistent with the composition of limestone and ...

Defining appropriate environmental flow regimes and criteria for the use of environmental water allocations requires experimental data on the ecological impacts of flow regime change and responses to environmental water allocation. Fish assemblages in one regulated and one unregulated tributary paired in each of two sub-catchments of the Hunter River, coastal New South Wales, Australia, were sa...

INTRODUCTION In spite of its importance as an experimental model, the information on the great cardiac vein in pigs is sparse. OBJECTIVE To determine the morphologic characteristics of the great cardiac vein and its tributaries in pigs. METHODS 120 hearts extracted from pigs destined to the slaughterhouse with stunning method were studied. This descriptive cross-over study evaluated continu...

In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Tisza River and its tributaries, and thereby used the sequential extraction method, geochemical normalization, the calculation of the enrichment factor (EF), and the methods of statistical analysis. The chemical fractionation of Ni, Cu, Zn, Cr, Pb, Fe, and Mn, carried out by using the mod...

The Preble’s meadow jumping mouse (Zapus hudsonius preblei [PMJM]) is a rare rodent of southeastern Wyoming and central Colorado that has been the center of debates regarding subspecies’ genetic identity and the application of the Endangered Species Act. I analyzed a 7-year PMJM mark–recapture data set using a temporal symmetry model (Pradel model) to estimate apparent survival (u), recruitment...

The coincidence of floods in the mainstream and its tributaries may lead to a large flooding downstream confluence area, flood risk analysis is very important for prevention disaster reduction. In this study, multiple regression model was used establish functional relationship among magnitudes tributaries. mixed von Mises distribution Pearson Type III were selected fit probability annual maximu...

measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...
