Spotted Owl, Flying Squirrel, Truffle Symbiosis
Throughout the world there are many animals, plants, fungi and numerous other living organisms that are influenced by the overall condition or adaptations of other organisms. Whether it is a symbiotic relationship or a predator/prey relationship there are many ways in which animals and other living organisms operate and live; both dependent on others and their own adaptations. The point is that there are many relationships that provide a basis and means for the survival of a variety of different species around the world. This relationship is very apparent in the scientific findings regarding northern spotted owls (Strix Occidentalis), flying squirrels (Glaucomys Sabrinus), and truffles, which can include many varieties but especially Tuber Gibbosum in the Pacific Northwest and northern territories. Together, these animals and fungus are dependent on one another for both nutritional and reproductive reasons. The northern spotted owl, which is the dominant predator in this food chain, is threatened, as it requires special conditions in which to survive. The first condition for this owl is that it requires an old growth forest. An old growth forest is one, which has been around so long that is has attained biological characteristics that are unique. Due to continuous logging it is easy to see why the northern spotted owl is on the verge of being an endangered species. The northern spotted owls main source of nutrition is the northern flying squirrel. This squirrels main preference is to also reside in old growth forests as they provide optimal site for building nests and finding food. Truffles are the third part of this system and happen to be one of the primary food sources for the flying squirrel. Typically, truffles are found on Douglas fir trees, helping them in absorption of water and nutrients from the soil. Altogether these three individual organisms make up a circle of life and are not only vital to the health and wellbeing of each other, but also the well
