What is the average age of a mouse

Indik, et al. Commensal populations of Mus musculus are generally stable and densities can be as high as 10 mice per square meter. In the wild, populations are less stable and densities may be less than 1 mouse per square meters. Overall, populations are flourishing and are in fact aided by human construction of houses, barns, and other structures.

Mus musculus often refers to several fairly distinct kinds of mice. As many as seven separate species may be placed under Mus musculus , such as Mus domesticus , western European house mice, and Mus castaneus , southeastern Asian house mice. The former refers to a genetic strain with inner ear defects, causing the mice to weave, turn in circles, and wobble when they walk.

The latter refers to a pathological condition causing mice to twitter constantly with a "song" resembling that of a cricket. Sage, et al. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.

In otherwords, Europe and Asia and northern Africa. In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Found on all continents except maybe Antarctica and in all biogeographic provinces; or in all the major oceans Atlantic, Indian, and Pacific.

Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.

Convergent in birds. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Jackson, H.

Life history traits averages Female sexual maturity 42 days Male sexual maturity 42 days Gestation 19 days Weaning 22 days Litter size 7 viviparous Litters per year 5. PubMed [ ] Dou et al. On average, the litter size ranges from 6 to 8 pups. On average, you are looking at least 32 to 56 pups each year from one female mouse. The mice reproduce each year, and the mother can mate immediately after giving birth.

So you could be looking at a new litter within 25 days. To make matters even more complicated, the female baby mouse is capable of reproduction at 6 weeks. So, they can start producing pups of their own and have about 10 litters of their own per year. In a theoretical situation, two mice that sneak into your home could give birth to 60 in a year. Of these new mice, about 21 to 30 are female mice capable of having their babies within a month, which can theoretically lead to 5, mice in just one year.

One mathematician calculated it to be 5 million mice per year, that is if it were a perfect world for mice. The average lifespan of a mouse is about 12 months in the outdoors. But when they take refuge in your house, they can live up to 2 or even 3 years.

You may be thinking that you can wait for the mouse to die on its own but what about its babies and the babies of their babies? The rate at which these breeding machines multiply is almost unbelievable. In the wild, they are an important part of the food chain. Many large birds feed on them to sustain their existence, just like mice feed on insects to sustain theirs.

In a way, they are maintaining balance, but inside your home, they are only bringing disease and destruction so if you are in the Houston area and need our services make sure to contact us online or give us a call today.
