A rat is a small nearly omnivorous rodent of the genus Rattus which comprises 56 different species of what is commonly known as the Old World Rats or true rats who originated in Asia.
There are 56 species of Old World Rat, the most well-known of which are Norvegicus; the Black Rat, Rattus rattus, also known as the Asian Brown Rat, the Brown Rat, the Ship Rat and the Roof Rat; and the Polynesian Rat, Rattus exulans.
The Black Plague is believed to have been caused by the micro-organism Yersinia Pestis, carried by the rat flea Xenopsilia Cheopis which preyed on Rattus Rattus living in European cities of the day; it is noteable that these Roof Rats were not carriers, but were also victims themselves.

The most well-known species are the Black Rat Rattus rattus, and the Brown Rat Rattus norvegicus.
These are of the species Rattus norvegicus, which originated in the grasslands of China and spread to Europe and eventually, in 1775, to the New World.
The Black Plague is traditionally believed to have been caused by the micro-organism Yersinia pestis, carried by the rat flea Xenopsilia cheopis which preyed on Rattus rattus living in European cities of the day; it is notable that these rats were also victims themselves.

The most well-known rat species are the Black Rat Rattus rattus and the Brown Rat Rattus norvegicus.
Pet rats are Brown Rats descended from those bred for research, and may be called "fancy rats." But they are still the same species as the common city "sewer" rat.
The Black Plague is traditionally believed to have been caused by the micro-organism Yersinia pestis, carried by the rat flea Xenopsylla cheopis which preyed on Rattus rattus living in European cities of the day; it is notable that these rats were also victims themselves.

We tested this idea by 1) demonstrating the connection between removal experiments and regression estimates of competition with those obtained from isodars (regressions that implicitly incorporate evolutionarily stable strategies of habitat selection) and 2) evaluating whether interspecific competition inferred from isodars corresponded with the inferences emerging from regression and field experiments.
Previous removal experiments on two herbivorous rodents occupying coastal wet heathlands in eastern Australia documented that competition between Rattus lutreolus and Pseudomys gracilicaudatus is asymmetrically biased in favor of the much larger Rattus.
Rattus compete effectively with Pseudomys in both "wetter" and "drier" patches of heath whereas Pseudomys appear to exert a competitive effect in only the drier sites.

 Do you consider that rats are mice?
Because of their physiologies, I suppose it is acceptable to group rats and mice together, but I don't think that we should forget that they are very distinct creatures.
That is one of the differences between mus musculus and rattus rattus.
There are lots of variations within individual species, and some of the visible variations (such as colour) are more obvious to the eye than the underlying differences between species.

 EFFECTS OF FIRE ON THE BROAD-TOOTHED MOUSE, MASTACOMYS FUSCUS,
A before-after-control-impact research program was conducted to investigate the effect of fuel reduction burns in buttongrass moorlands on the broad-toothed mouse, Mastacomys fuscus, swamp rat, Rattus lutreolus, and swamp antechinus, Antechinus minimus.
Capture rates were low with Rattus lutreolus trapped the most (2.5, 1.7, 3.9 individuals captured/100 trap nights at sites A, B and C respectively) followed by Antechinus minimus (2.7, 1.7, 1.6) and M.

The diets of Rattus fuscipes and R. lutreolus from a site in central southern Victoria were investigated by faecal analysis.
lutreolus was predominantly herbivorous; in heath it selected the basal stems of certain cyperaceous herbs, and in forest it ate non-sclerophyllous grasses.
fuscipes showed little dietary overlap with R. lutreolus; in forest it was reliant on fungi and fibrous plant material from particular grasses; in heath it relied on particular cyperaceous species in winter, and ate primarily fleshy fruit, seed and arthropods in summer.

Laboratory hybridization of Australian Rattus fuscipes and Rattus Lutreolus and its karyotypic confirmation
This paper reports successful laboratory hybridization of R. lutreolus lutreolus (2n = 42) and R. fuscipes assimilis (2n = 38).
The hybridization indicates a closer relationship between these species than previously accepted, but there is no evidence of natural hybrids, perhaps due to an ecological separation observed in the field and to behavioural obstacles to mating observed in the laboratory.

The only rats which live around human habitation and cause damage to stock or property are the two "vermin" species, the fl or ship rat: Rattus rattus and the brown or norway rat: Rattus norvegicus.
These two imports tend to stay quite close to human settlements, cities and suburbs where they can hang out in the waste people dump around the place.

Of the other small mammals, the bush rat, Rattus fuscipes, and the brown antechinus, Antechinus stuartii, favoured floristic groups that provided dense low cover.
Captures of the swamp rat, Rattus lutreolus, were clumped, and centred on several sites along the forest edge on impeded drainage where potential foods were common.
The long-nosed bandicoot, Perameles nasuta, and the southern brown bandicoot, Isoodon obesulus, were uncommon and clear microhabitat preferences were not displayed.
