There are a growing number of large-scale, complex hydrologic models that capable simulating integrated surface and subsurface flow. Many coupled to land-surface energy balance models, biogeochemical ecological process atmospheric models. Although they being increasingly applied for prediction environmental understanding, very little formal verification and/or benchmarking these has been performed. Here we present the results an intercomparison study seven surface-subsurface based on series...

The accurate characterization of fractured geologic medium, imaging fracture patterns and their connectivity have been a challenge for decades. Recently, hydraulic tomography has proposed as new method the conductivity ( K ) specific storage S s distributions media. While encouraging results obtained in field, not rigorously assessed controlled laboratory setting. In this study, we assess performance transient (THT) dolomitic rock block. block is characterized through flow‐through tests...

An 8-week feeding trial was conducted to evaluate the effects of dietary probiotics on growth, non-specific immune responses and disease resistance in juvenile rainbow trout, Oncorhynchus mykiss. Fish averaging 5.8 ± 0.8 g (mean SD) were fed one five experimental diets; control (Cont), four other diets prepared by supplementing single 1 (Bacillus subtilis; SP1, 0.5%), 2 licheniformis; SP2, multi-probiotics (B. subtilis + B.

Intestinal inflammation in farmed fish is a non-infectious disease that deserves attention because it major issue linked to carnivorous fishes. The current norm formulate feeds based on plant-derived substances, and the ingredients have antinutritional factors are known cause intestinal fishes such as Atlantic salmon. Hence, we studied inflammatory responses distal intestine of salmon received feed rich soybean derivatives, employing histology, transcriptomic flow cytometry techniques. fed...

The importance of fracture intersection mixing rules, complete and streamline routing, on simulated solute migration patterns in random networks is assessed. For this purpose, based geological evidence, two‐dimensional model having power law length distributions lognormal permeability are considered. Different network structures accounted for by the distribution, ranging from composed infinite fractures to percolation with constant fractures. Comparison particle statistics shows that there...

Abstract This study demonstrates the importance of including and appropriately parameterizing peatlands forestlands for basin‐scale integrated surface–subsurface models in northern boreal forest, with particular emphasis on Athabasca River Basin (ARB). With a long‐term water balance approach to ARB, we investigate reasons why downstream mean annual stream flow rates are consistently higher than upstream, despite subhumid deficit conditions regimes. A high‐resolution 3D variably saturated...

Imaging flow cytometry (IFC) is a powerful tool which combines with digital microscopy to generate quantitative high-throughput imaging data. Despite various advantages of IFC over standard cytometry, widespread adoption this technology for studies in aquatic sciences limited, probably due the relatively high equipment cost, complexity image analysis-based data interpretation and lack core facilities trained personnel. Here, we describe application examine phagocytosis particles including...

The ubiquitous presence of microplastics and their marine ecotoxicity are major public concerns. Microplastics ingested accidentally by the fauna or taken up indirectly through food chain. These particles can accumulate in cells tissues affect normal biological functions organisms, including defense mechanisms. There is limited information available about response immune to microplastics; degree uptake cells, different organs impact environmental concentrations microplastic matters that...

Abstract Snow algae blooms often form green or red coloured patches in melting alpine and polar snowfields worldwide, yet little is known about their biology, biogeography, species diversity. We investigated eight isolates collected from snow northern Norway, using a combination of morphology, 18S rRNA gene internal transcribed spacer 2 (ITS2) genetic markers. Phylogenetic ITS2 secondary structure analyses assigned six to the Raphidonema nivale, Deuterostichococcus epilithicus, Chloromonas...
