Analysis of footprints provides additional insights during monitoring of Duvaucel’s geckos (Hoplodactylus duvaucelii)

摘要: ABSTRACTThe use of tracking tunnels to record footprints is becoming an important tool for monitoring fauna. This study demonstrated that Duvaucel’s gecko (Hoplodactylus duvaucelii) (toe dimensions, foot length and area) can be used predict snout-to-vent (SVL). Back feet were larger than front and, as long this was taken into account, all anatomical features predicted SVL with R2 values > 0.73. Measurements area easy make provided 0.94–0.97. Footprint analysis a population geckos on Motuora Island in the Hauraki Gulf, confirmed presence island-born improved estimates number individuals. We propose image increase knowledge populations occur at low density, are cryptic and/or hard capture, being monitored by volunteers.
