A key consideration in assessing impacts of climate change is the possibility of synergistic effects with other human-induced stressors. In the ocean realm, climate change and overfishing pose two of the greatest challenges to the structure and functioning of marine ecosystems. In eastern Tasmania, temperate coastal waters are warming at approximately four times the global ocean warming average...
Abstract Rate-setting is a problematic area for newcomers to translation and established practitioners alike. Survey data generally support the view that translators feel underpaid money matters remain chief ethical pragmatic concern, but appropriate guidance almost entirely absent from introductory textbooks on profession documentation prepared by industry associations remains unsatisfactory. ...
We investigated the effects of overgrazing on the foraging behavior of livestock on a Mongolian steppe, by quantifying some behaviors of cattle, sheep and goats foraging in a lightly and a heavily grazed area in summer and winter. All animal species showed higher walking velocity and tended to show higher step/bite ratio when they foraged in the heavily grazed area than in the lightly grazed ar...
The forms and dynamics of soil phosphorus can be greatly affected by land use changes, which often involve changes in vegetation cover, biomass production and nutrient cycling in the ecosystem. Present research evaluates the impact of land use change on the amount of total organic and inorganic P, labile, moderately labile and nonlabile P pools in semiarid soils of central Zagros. Samples were ...
