Acting as a co-factor for hundreds of enzymes, zinc (Zn) is an essential trace metal required for organismal success across all phyla. When aquatic organisms such as fish are Zn deficient, growth, metabolism, and health are all negatively impacted. However, Zn in excess may also impair overall...

Hughes, Kenneth G., Klymak, Jody M., Hu, Xianmin, Myers, Paul G.

Strong spatial differences in diapycnal mixing across the Canadian Arctic Archipelago are diagnosed in a 1/128 basin-scale model. Changes in mass flux between water flowing into or out of several regions are analyzed using a volume-integrated advection–diffusion equation, and focus is given to...

Emerging devices, such as those based on carbon (in the form of graphene or nanotubes) or III-V compound semiconductors, are constructed on an atomic scale, where the transport is governed by the Schrödinger equation of quantum mechanics or the Boltzmann transport equation (BTE) of semi-classical...

The influence of the viable but non-culturable (VBNC) state on specific phenotypic traits of Escherichia coli O157:H7 as well as its transport behaviour in porous media was examined in this study. E.coli O157:H7 is a human pathogen capable of entering a VBNC state following exposure to sublethal...

This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...

The Atlantic meridional overturning circulation (AMOC) represents the zonally integrated stream function of meridional volume transport in the Atlantic Basin. The AMOC plays an important role in transporting heat meridionally in the climate system. Observations suggest a heat transport by the...

We present ocean model sensitivity experiments aimed at separating the influence of the projected changes in the “thermal” (near-surface air temperature) and “wind” (near-surface winds) forcing on the patterns of sea level and ocean heat content. In the North Atlantic, the distribution of sea...

The impact of paleoatmospheric forcing and sea ice distribution on the circulation of the subpolar North Atlantic is examined in a regional eddy-permitting ocean model. We focus on water mass formation and the pathway of the North Atlantic Current. Paleofluxes are obtained from a coupled...

Calvo-Polanco, M., Senorans, J., Zwiazek, J.J.

Background: Flooding reduces supply of oxygen to the roots affecting plant water uptake. Some flooding-tolerant tree species including tamarack (Larix laricina (Du Roi) K. Koch) produce adventitious roots in response to flooding. These roots were reported to have higher hydraulic conductivity...

Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...
