    Migration. Objectives of the Global Ignatian Advocacy Network GIAN of Migration. Forced migration is not only one of the greatest challenges we encounter in the world today, but a clear indicator of how the causes of injustice operate as a driving force for the expulsion of at least 71 million people in the world UNHCR figure in 2018.

    Migration distance and maternal resource allocation

    Mar 12, 2021 Program in Ecology, University of Wyoming, Laramie, WY, 82071 USA. Corresponding author. ... Shorter distance migrants completed migration sooner and gave birth earlier, seemingly trading off more time for offspring to grow and develop over greater access to resources. Thus, movement tactic had profound downstream effects on birth timing.

  • Adsorption of Cesium by Synthetic ClayOrganic Matter

    Adsorption of Cesium by Synthetic ClayOrganic Matter

    The strong correlation observed in situ between the bioavailability of radiocesium and soil organic matter content is paradoxical given the lack of coordination chemistry of cesium and its strong affinity for clay minerals. The aim of this work is to determine whether the adsorption of soil polymers, a protein and a polysaccharide, on reference clay minerals decreases cesium adsorption ...

    Aug 15, 2020 Migration as innate behavior. Migration is the long-range seasonal movement of animals. An evolved, adapted response to variation in resource availability, it is a common phenomenon found in all major groups of animals. Birds fly south for the winter to get to warmer climates with sufficient food, while salmon migrate to their spawning grounds.

    The cesium-containing liquids varied in ionic strengths, and often had high electrolyte contents, mainly in the form of NaNO3 and NaOH, reaching concentrations up to several moles per liter. In this study, we investigated the effect of ionic strengths on Cs migration through two types of porous media silica sand and Hanford sediments.

    The Migration Ecology of Birds ScienceDirect

    Migration occurs to some degree in most species of birds that live in seasonal environments. It leads to massive twice-yearly changes in the distributions of birds over the Earths surface. Some migratory birds travel relatively long distances and they accumulate large reserves of body fat for the journey.

    Stream channel migration zones Washington State

    Stream channel migration zones. Channel migration is the natural process that describes how a stream or river channel moves over time. Channel migration can occur gradually, such as when a stream erodes away one bank and deposits sediment along the opposite side. It can also occur quite quickly during floods or high water events.

This surface and near-surface soil contamination by radiocesium may be susceptible to migration on vegetated sites due to plant facilitated 137Cs translocation. Once in the plant, the 137Cs will not only reposition within the soil profile, but grazing and predation ...
