Hypothesis

How do human activities influence the prevalence of amphibian pathogens?

Conclusion

Human activities significantly affect the prevalence of ranavirus in amphibians, while no significant relationship was found for chytrid infection.

Supporting Evidence

  • Eight ponds showed ranavirus infection with prevalence ranging from 0% to 63%.
  • Six ponds had frogs infected with chytrid fungus with prevalence ranging from 0% to 36%.
  • Distance to industrial activity and human habitation significantly influenced ranavirus prevalence.

Takeaway

This study found that where people live and work can change how sick frogs get from certain diseases.

Methodology

The study involved sampling frogs from various ponds and testing them for two pathogens using molecular diagnostics.

Potential Biases

Potential biases may arise from the sampling strategy and the environmental conditions of the study sites.

Limitations

The study's findings are based on correlations and may not establish direct causation.

Participant Demographics

Frogs from 11 populations in central and northeastern Ontario, Canada.
