A comparative analysis of scoring methods for chemical discrimination of prey by squamate reptiles.

摘要: In studies of squamate responses to prey chemicals presented on cotton-tipped applicators, investigators typically record several responses, each which gives only part the overall picture. The tongue-flick/attack score (TFAS) is a widely used composite measure response strength that accounts for attack, its latency, and number tongue-flicks. We present data analyses these variables investigate utility other possible variables. It concluded, both practical theoretical reasons, TFAS two modifications it are best measures strength. Uses statistical derived from discussed. recommended information tongue-flick rate, individuals attacking, latency attack be presented.
