Hypothesis

Does poor condition precede infection in field voles?

Conclusion

Poor condition increases the likelihood of infection, which in turn leads to a further decline in condition.

Supporting Evidence

  • Individuals with low RBC and lymphocyte counts had increased probabilities of developing monocytosis.
  • High indices of infection were generally followed by a decline in RBC and lymphocyte counts.
  • Poor condition predisposes individuals to infection, creating a vicious circle.

Takeaway

If a field vole is not feeling well, it can get sick more easily, and being sick can make it feel even worse.

Methodology

Field voles were sampled monthly for 2 years, measuring haematological indicators of infection and condition.

Potential Biases

Potential bias due to environmental factors affecting health and infection rates.

Limitations

The study was limited to specific seasons and did not include juvenile voles.

Participant Demographics

Field voles from three populations in Northumberland, UK.
