Abstract:
... Soil resources are determined with the use of spatial indicators of soil genetic differences. This approach is the universal basis for an accounting of soil resources on a global, regional, and local scale. The spatial indicators include the areas of functioning soils and their detailed characteristics: the contour size, the area in units of measurement, their number, the nature of border crossing ...

Abstract:
... Two herbivorous species that share a single plant can interact indirectly with one another, even without direct interaction. One type of indirect interaction is exploitative resource competition, which results from a reduction in plant biomass; another type is that caused by changes in plant traits. These are referred to as indirect effects, mediated, respectively, by biomass and plant traits. The ...
