Hypothesis
Does the prevalence of Sin Nombre virus (SNV) in deer mice vary spatially and temporally across different islands?
Conclusion
The prevalence of SNV in mouse populations varies by island and location, indicating complex dynamics in the relationship between deer mice and the virus.
Supporting Evidence
- SNV prevalence in mice varied from 0% to 71% across different islands.
- Capture success and density estimates were lower in 1996 compared to 1995.
- Significantly more adult mice were seropositive than juvenile or subadult mice.
Takeaway
Scientists studied mice on California islands to see how many had a virus called SNV. They found that the number of sick mice changed a lot depending on where they were.
Methodology
Mice were trapped at two locations on three islands, and blood samples were tested for SNV antibodies.
Potential Biases
Potential bias due to non-systematic trapping and incomplete data from previous years.
Limitations
Sampling was limited to one location per island, and mouse densities were not systematically estimated.
Participant Demographics
Mice captured included juvenile, subadult, and adult Peromyscus maniculatus.
