Fish migrate every year from the open Pacific Ocean to the coastal regions of the Pacific Northwest in order to spend about 5-6 weeks recreating. During this time contains also migrate to these coastal areas to feed on the salmon a large component to their diet. This organic interaction has been an important factor of the ecosystem in the Pacific Northwest for many years and now that humans have imposed on this procedure by overfishing we are seeing changes in the ecosystem itself. When knowledge of this issue has been around for approximately 30 years, researchers only commenced researching that beginning in the early 90's. Relating to this research the ongoing issue of overfishing is already beginning to show its effects around the ecosystem, what may happen for the forests and animals of the Pacific Northwest in the event that this issue is definitely not solved?
Through the study of Doctor Tom Reimchen and other researchers, an conversation between salmon and the jungles of the Western has been learned. Each year black and grizzly bears travel from far away towards the streams and rivers inside the Pacific Northwest to feed on the salmon that migrate presently there during their 6 week spawning period. This causes a local interaction, when the bears get a fish they take it into the forest so they can take in it rather than be annoyed. Usually the bears just eat about half of each seafood they capture and leave the rest on the forest flooring, which is after that consumed by simply birds, different small family pets and bugs. Through the decomposition of the fish as well as the body wastes from the bears and also other animals, the soil inside the forest absorbs nutrients along with nitrogen from your salmon. " The use of stable nitrogen isotopes allows us to discover the comparable contribution of salmon towards the ecosystemвЂќ (Reimchen 2001: 14), this exploration showed that nitrogen 12-15, an isotope of nitrogen is present in a large number of the plants in the Pacific Northwest woodlands. Nitrogen 12-15 is mostly present in marine algae and fish are...
