Natalia, You may want to look at Ilkka Hanski's 1998 Book Metapopulation Ecology.
In short, the source-sink concept was formulated by Brown and Kodric-Brown to describe patchy populations with different mean malthusian parameters r_m. Sinks had r_m<0, sources had them >0. Levins' original metapopulation model assumed more homogeneous populations. Hanski and others have broadened the definition of 'metapopulation' to include source-sink and other patchily distributed landscapes.
