Document Summary
Black death in 14th century was caused by bacteria that was transmitted by rats and fleas. What is parasitism: parasitism similar interaction (+/-) as disease, agents: macroparasites. Large, multicellular organisms that feed off, but rarely kill their host. Insects, tapeworms, ticks, sea live: endo- and ectoparasites (inside versus outside) Some parasites may also transmit disease (can be vector: ex. Flea is parasite but can transmit bacteria for black death: ex. New salmon will/won"t be free of parasites: on their way back to sea, spill back occurs where the infected domestic salmon infect the babies returning back to sea, ex. How to study disease and parasitism: natural experiments: look for the effects of natural variation, manipulative experiments: induce variation experimentally and look for effects, ex. Thought it could be from nematode worm: removed the parasite. Midterm: 17, all multiple choice, 34 questions, no calculators, know how to interpret graphs.
