GEOG 111 Lecture Notes - Lecture 14: Emerald Ash Borer, Biogeographic Realm, Biogeography
Document Summary
Geog 111 - lectures twenty seven and twenty eight (last) - 12/5 + 12/9. Example of invasive species lamprey"s in great lakes let in by human interference of river system, parasites that suck on fish and eat their blood threatening many native great lake species. Another example zebra mussels in the finger lakes hudson river and great lakes, has an effect on economics, environment, and biology, was brought here unintentionally. Incredibly effective invasive species killing ash trees but can survive within the wood for a while, and not detectable usually for 1-2 in infected tree and kills trees after 2-3 years. Has no known natural predators, extensive dieback for the trees is common, can alter the habitat, accelerate local hydrologic and sediment cycle, is a health and safety risk, aesthetic risk. At the broadest level the planet can be divided up into realms, which defy political and even continental boundaries, based on the plants and animals in each one.
