The Effects of Foreign Species Introduction On An Ecosystem The effects of foreign species introduction into an ecosystem are very profound. From small microorganisms to species of large mammals‚ many foreign species introductions occur every day. New implications of their introduction are found just as often. When a foreign species is introduced into an ecosystem‚ often the ecosystem contains no natural predators for the new species. This lack of predators sometimes leads to; in conjunction

Determining Reference Ecosystems and the Historical Range of Variability Each and every year‚ trees record information within their growing rings and dendrochronology is the study of these tree-rings. Although tree-ring analysis is limited by the spatial scale of the climates where trees can grow and the temporal scale of the oldest possible age of a tree in a study area (183636 years ago)‚ it has proven to be a crucial tool in paleoclimatology and paleoecology. “To understand how ecosystems arrived at
