Bat data : Australia, Sydney
Metadata[+] Show full item record
Bat activity was sampled using the same study design as Threlfall et al. (2011), in 29 randomly selected replicate 5 5 km 'landscapes'. Landscapes were categorized based on the average level of urbanization and vegetation cover of each landscape, whilst also capturing variations in geology where possible. Bat activity was recorded using Anabat detectors (Titley Electronics, Ballina, Australia) onto a CF storage card via a zero-crossing interface (Z-CAIM, Titley Electronics), in the bat maternity season between October and December 2008, as this is when resource requirements are likely to be highest. A Canonical Correspondence Analysis (CCA) was performed to assess the relationships between individual species activity, local, landscape and prey variables.
