Abstract The ideas examined and the results presented in the last unfinished manuscript of Friedrich Ruttner have been further developed. Within the 6 populations of the Near East distinguishable by morphometry, the bees of Massandaran in Iran occupy an important position due to their large size. Even sea-level bees exceed the size of the bees of the elevated region of Central Iran, which seems to contradict Bergmanns' a rule. An extended study had revealed that this population, clearly belonging to the subspecies Apis mellifera meda, shows a very distinct Size increase from the Caspian Sea to the northern slope of the Elbrus Mountains, rising to 2 200 m in elevation. A similar but less pronounced ecocline with a marked increase in size can be found reaching up from the Mediterranean coast to the elevated Central Iranian region. The general pattern within A. m. meda in the region along 36 degrees N latitude thus generally confirms Bergmann's rule, thus providing a fineexample of an ecoclinal structure. However, size differences between the extremes, i.e., the Mediterranean and the coast of the Caspian Sea remain marked, which indicates an additional genetic component linked to a differenthistory of the populations. This might prove to be an interesting aspect, as the area covered by A. meda is suspected to have played a major role in the evolution of A. mellifera.
