Hypothesis
Does arsenic treatment affect the success of DNA extraction from bird specimens?
Conclusion
Foot pad samples generally yield better PCR success than body skin samples, especially in older specimens.
Supporting Evidence
- Foot pad samples had higher PCR success rates than body skin samples.
- Older samples showed lower PCR success, likely due to DNA degradation.
- Arsenic treatment negatively impacted PCR performance at high concentrations.
Takeaway
This study found that using foot pads from birds is better for getting DNA than using their body skin, especially for older birds.
Methodology
PCR success was compared between arsenic-treated and untreated foot pad and body skin samples from 64 European Jay specimens.
Potential Biases
Potential bias due to the age of specimens and unknown arsenic concentrations in foot pads.
Limitations
The study's findings may not apply to all bird species or to specimens treated with different preservation methods.
Participant Demographics
European Jay (Garrulus glandarius) specimens from various collection dates.
