Table 1 Categories and their respective description used for rating the likelihood of grey seal predation and fox interaction.
From: Assessing harbour porpoise carcasses potentially subjected to grey seal predation
Category | Definition |
---|---|
Definite | The attack was observed and the carcass was retrieved straight after or the origin of trauma could be verified using genetic methods |
Likely | It is highly likely that the documented trauma is the result of grey seal predation; the majority of parameters have been found |
Possible | It is possible that the documented trauma is the result of grey seal predation; some of the parameters have been found; potentially some indication of a different origin of trauma |
Escape | Scar tissue is present, indicating previous interactions with a grey seal, but the cause of death is not directly related |
Unlikely | It is unlikely that the documented trauma is the result of grey seal predation; the majority of parameters have not been found; clear indication of a different origin of trauma |
Fox | It is unlikely that the documented trauma is the result of grey seal predation, but indicators of an interaction with a red fox have been found |
