During the El Niño phase, the jet stream is located south through California, allowing for warmer temperatures and more heavy rains to occur, particularly in the southern portions of the state. During the La Niña phase, the jet stream is much further north, and therefore the far northern portions of California are wetter, while the southern ...
The bushy-tailed woodrat, or packrat (Neotoma cinerea) is a species of rodent in the family Cricetidae found in Canada and the United States. [2] Its natural habitats are boreal forests, temperate forests, dry savanna, temperate shrubland, and temperate grassland.
Pack rats build complex houses or dens made of twigs, cactus joints, and other materials. These contain several nest chambers, food caches, and debris piles. Dens are often built in small caves or rocky crevices, but when close by human habitations, woodrats will opportunistically move into the attics and walls of houses.
The species only becomes sociable during breeding season. [22] The breeding season of eastern wood rats depends on the climate. Those in warmer climates (e.g. Florida and Georgia) can reproduce all year, while eastern wood rats in higher latitudes (e.g. Kansas and Nebraska) breed from early spring to mid fall.

Specifically, those who do not migrate to warmer climates or hibernate for winter are most likely to scatter hoard. [6] [7] [8] This behavior plays an important part in seed dispersal, as those seeds that are left uneaten will have a chance to germinate, thus enabling plants to spread their populations effectively. While it is clear why some ...
