Although these biomes are listed as ideal, rats live on every continent except Antarctica. ]]> 2016-05-11 14:29:13 UTC https://padlet.com/javatsemone/etjt6oiky071/wish/110339080 The Norway Rat javatsemone https://padlet.com/javatsemone/etjt6oiky071/wish/110342030 Has adapted to survive in colder climates (Animal Diversity Web, 2004). ]]> 2016-05-11 14:39:55 UTC https://padlet.com/javatsemone/etjt6oiky071/wish/110342030 Interactions jingyizhang111 https://padlet.com/javatsemone/etjt6oiky071/wish/110568049 Dispersion pattern-Rats live in complex social groups. The group contains a set hierarchy and all rats know their places. Because they are territorial, rats live in clumps with their social group.
Density dependent factors that impact rats- food shortage, illness, water shortage, resource shortage
Independent factors that impact rats- weather, natural disaster, human predation

It shows in the way that they reproduce: profusely. One female can have up to 60 babies a year. However, they will always hit a carrying capacity because an increase in offspring means a decrease in food and shelter and an increase of diseases. Therefore their populations will always level off.
 
Specific research in England has shown that the maximum log-likelihood reached a plateau between K = 3 and K = 5 (Haniza, et al., 2015).

This means the rat has a relatively constant mortality at all life stages.

Therefore, an earthquake could destroy their homes, impacting their ecosystem. This chance event could kill many rats, and it also could cause a genetic drift.
A forest fire would also impact the rat's ecosystem because they also tend to live in forests; therefore, a fire would force the rats out of their habitats and. This chance event can also kill many rats and cause genetic drift.
