Reproductive Parameters in Rattus rattus and Rattus exulans of Hawaii, 1968 to 1970

Journal of Mammalogy, 1972
Reproductive parameters were assessed in populations of the roof rat ( Rattus rattus ) and the Polynesian rat ( Rattus exulans ) in Hawaii for 1 year as a step in understanding population regulation in these species. Populations of the roof rat undergo a yearly cycle in which density is highest and reproduction is lowest in the winter.

Journal of Mammalogy, 1971
In conjunction with studies of the rodent populations of the former nuclear test site at Eniwetok Atoll, the feeding patterns of Rattus rattus and Rattus exulans were determined by food acceptance tests, histological examination of stomach contents, and observation of animals under both natural and cage conditions.

Paracrystalline Hæmoglobin as a Species Difference between Rattus norvegicus and Rattus rattus

Nature, 1961
THE common laboratory white rat is almost always the albino variety of the Norway rat (brown rat, Rattus norvegicus)1,2 and only exceptionally the albino variety of the black rat (Rattus rattus)3. The two species are morphologically similar, which makes it rather difficult to distinguish them.

The hyoid complex of Rattus rattus rufescens

Journal of Zoology, 1967
The hyoid apparatus of the rat consists of an anteroposterior compressed and somewhat arched basihyal, the small anterior cornua and the more prominent posterior cornua. The ceratohyal is the only movably articulated element of the anterior cornu and is generally lost during the normal methods of preparing skeleton.

Rattus rattus (Black rat)

1971
As we now know, there are two basic chromosome numbers for R. >rattus, one 42 (Folio 229) and the other 38. Apparently Robertsonian processes were involved in the establishment of the two karyotypes (3). Data are rapidly accumulating in regard to the distribution of these two basic numbers over the globe.
