From country parasite to city parasite
What if some quintessentially-Princeton squirrels were introduced into the Harvard campus? They're likely to be an even greater pest in Cambridge — because not all of their parasites will go along. EEB professor Andrew Dobson and researchers at U.C. Santa Barbara conducted the first broad quantitative study showing that introduced species lose half their native parasites. Unfortunately for the 26 species of molluscs, crustaceans, fishes, birds, mammals, amphibians and reptiles studied, the parasites that did remain were just as prevalent after the move.
