Rattus exulans is the smallest of the three rats closely associated with humans.
exulans is recognised as a predator of native insects, lizards and birds, browser of native flora and an agricultural pest.
Rattus exulans is considered to be a fairly sedentary animal with a limited home range (Spennemann, 1997).

Descendants of Norwegian rats bred for research, these animals are often called "fancy rats", "coloured rats" or "colour rats." Domesticated rats tend to be both more docile than their wild ancestors and more disease prone, presumably due to inbreeding.
There are over 50 species of rats, the most well-known of which are the Brown Rat, Rattus norvegicus; the Black Rat, Rattus rattus; and the Polynesian Rat, Rattus exulans.
Like mice, rats (especially albino Rattus norvegicus) are frequently subjects of medical, psychological and other biological experiments due to their rapid growth to sexual maturity and because rats are easily kept and bred in captivity.

These sequences are used to produce phylogenetic trees which correspond to the migratory history of the rats, and by extension, the humans that carried them from island to island.
With the complete mt genomes of norvegicus, exulans, and praetor I was able to design primers specific to regions that are conserved among these three species, making it more likely that these primers will be effective on other rat species to be sequenced in the future, such as R.
Once R. tanezumi and R. rattus are added to the list of sequenced mt genomes this will be a very interesting tree to look at, and will hopefully add a new perspective on how rats have come to colonize Oceania.

 Non-Native Species A Brief Account
The Norway Rat is the largest of the four, is rather more large-bodied than the Black Rat, which has a longer tail and is a more agile climber.
Both measure about 40cm from head to tail, in contrast to the smaller House Mouse, which is only about a quarter to half the size; the Polynesian Rat is slightly larger but still is the smallest Rattus species, its native home in the humid tropical regions of South-east Asia.
These venturing omnivores seldom shun potential food sources, and consume almost anything from grains, vegetables, meat, milk, confectionary, soap, milk, eggs, or less nutritious structures such as sofas and wood to grind of the tips of their ever-growing incisors, adapted originally for the consumption of plant stems and other vegetable materials.

 Something old, something new: Do genetic studies of contemporary populations reliably represent prehistoric populations ...   (Site not responding. Last check: 2007-10-10)
In certain locations in the Pacific, for example Easter Island and the main islands of New Zealand, R. exulans are no longer present due to competition with the later-introduced European species of rat, R. rattus and R. norvegicus (in New Zealand, populations of R. exulans remain on a few small offshore islands).
Comparison of ancient and modern R. exulans populations can perhaps provide a new kind of model that can be applied to studies of human settlement.
This is particularly the case for R. exulans remains throughout the Pacific.

We present results of mtDNA variation in both ancient and modern populations of the Pacific Rat (Rattus exulans), an animal that was transported by humans as they settled the Pacific islands.
exulans populations on Pacific islands will to some degree reflect the level of prehistoric human contact with those islands, and thus will be tied to island accessibility.
High levels must be the result of either multiple introductions by humans or in situ evolution over an extended time frame; however, lack of variation could conceivably be the result of recent population crashes, and may therefore not be reflective of low levels of human mobility.

This study involved using commensals to trace early human migration of the Pacific peoples - in this case it was the Pacific rat, Rattus exulans.
exulans also have several other properties that make them so ideal to "lab rats" to sequence.
They also don't crossbreed with the European rat (Rattus rattus and Rattus norvegicus), so there are no problems with reticulate branching.
