Percentage of mice testing positive for hantavirus Name: ___________________ Date: __________________________ The Role of Community and Habitat in Disease Protection By Jason Nappy and Evanice Pineda-Delgad A. The percentage of carrier species (capable of transmitting the Hanta virus) at control sites, which were left untouched, and experimental sites where non-carrier species were removed. B. The relationship between the percentage of mice testing positive and the number of common different mouse species in the tested sites.   30 60% 20 Percentage of mice testing positive for hantavirus 40% Portion of species capable of transmitting hantavirus 10 20% Number of Common Different Mouse Species Control Sites:Untouched Experimental Sites: Species Removed Sampling Period Over Time 1. According to graph A, what happened to the prevalence of carrier species when non-carrier species were removed by scientists? ____________________________________________________________________________________ 2. In graph B, as the number of common different mouse species increases, what happens to the percentage of mice that test positive for hantavirus? 3. What happens to the percentage of mice that test positive for hantavirus when the number of different common species decreases? 4. In which type of habitat do you think hantavirus would be more common, a forest with many mouse species or a deforested area with fewer mouse species? 5.In which type of habitat would a human be more likely to contract hantavirus? 6. How does a diverse community affect the spread of the hantavirus?
