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.

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.

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.

Leptospirosis in Rattus norvegicus and Rattus rattus in Israel.

Israel journal of medical sciences, 1982
Leptospires were isolated from 21.2% of Rattus norvegicus (the brown rat) and 9.9% of Rattus rattus trapped in a survey of urban and rural areas in Israel. Microagglutination antibodies were found in sera of 9.4 and 8.1% of these rats, respectively. The 191 strains isolated belonged to six serogroups: Leptospira icterohaemorrhagiae (169), L.
