Evolving Marine Health Threats to Humans,aturally retain the terminology and notation of Chapter 1.2, with one difference. By convention we will denote transformations by lower-case Greek letters, and elements of the set by lower-case Roman letters. In particular, if α maps . onto ., then . will be called the image of . under α, and we write α. = . or α(.) = ..
