Crossland et al Hochstetter's frog site occupancy data.xls

The study involved conducting 10 metre transect surveys in streams in the Hunua Ranges, New Zealand between July to August 2006. In each survey, we searched for juvenile, subadult and adult Hochstetter's frogs. There are four data sheets in the file. Sheet 1 is frog detection data (presence/absence per survey). Sheet 2 is frog abundance data (total number of frogs observed per survey). Sheet 3 is detectability covariates; data for air temperature, number of refugia and rainfall are both raw data and standardised data ([x-mean] / standard deviation). Sheet 4 is occupancy covariate data for predator control history at sites.
