FUTURE DIRECTIONS
•Optimize protocol to efficiently target mammalian and avian predators/attackers
•Potential applicability in invasive species monitoring
ARTIFICIAL PREY MODEL BITE / ATTACK MARK ASSESSMENT RESULT
If identifiable -
Predator group
(e.g. bird)
Species level
?

RESULTS
DISCUSSION
•Standardized approach
•Robust identification of attackers
•Decreases number of unidentified attacks (minimizes data loss)
•Reveals high misidentification rate from visual assessment
METHOD
Amplicon
Sequencing
A PILOT STUDY
Attacker identification from bite
marks in clay model studies is often
likely to be biased and lacks a
standardized approach.
In a field-based study, we used clay
models of fire salamanders to test
attacker identification from residual
saliva DNA left on bite marks and
subsequently compared visual and
genetic assessments.
