Translation is the communication of the meaning of a source-language text by means of an equivalent target-language text. The English language draws a terminological distinction (not all languages do) between translating (a written text) and interpreting (oral or sign-language communication between users of different languages); under this distinction, translation can begin only after the appearance of writing within a language community.
Scientists investigating the impacts of climate change need to understand how multiple environmental stressors combine to affect individuals, populations and ecosystems. In marine ecosystems, stressors appear to have a significant effect on the larval stages of organisms.
