    Bat data : Australia, Sydney
    (2015) Threlfall, Caragh G.; Law, Bradley; Banks, Peter B.
    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.

    Bat data : Brazil, Itabira
    (2005) Silva, Ricardo; Perini, Fernando Araújo; Oliveira, Wagner Rodrigo de
    Each site was surveyed monthly from September 2004 through August 2005, between 18:00h to 1:00, totalizing thirty-six nights and 252 hours of capture. The bats were captured using four mist nets (9 m x 2.5 m), totalizing 110m^2 of total net area in each area. The mistnets were checked every 30 minutes. Diversity indexes were calculated for each area

    Bat data : Michigan, Detroit
    (2014) Kurta, Alan; Teramino, Joseph A.
    Mist-netting was the survey technique over ultrasound-sensing because netting allowed for the elimination of repeat captures, which was required for statistical independence, and allowed for the determination of age ratios, sex ratios, and reproductive condition. Nets were placed over the rivers, perpendicular to the direction of stream flow, and underneath overhanging branches in order to block as much of the flight corridor as possible.

    Bat data : Czech Republic, Brno
    (1997) Gaisler, J.
    Four bat detectors were used, D-980 Pettersson, SKYE, and 2 QMC Mini. We made acoustic recordings of bats within the town of Brno, Czech Republic (230 km2, 350,000 inhabitants), from March till October 1993. The same habitat types were sampled under the same conditions as in 1977 (Gaisler, 1979). Most observations started 10 min after sunset, on the nights of new and full moon (‹ 1 night), and lasted 30 min. In total, we covered 55 such transects labelled 'standard' which encompassed 1650 min of monitoring. Standard transects were used for all comparisons.

    Bat data : Australia, Adelaide City
    (2015) Scanlon, Annette T.; Petit, Sophie
    Used echolocation call detectors (n = 378 detector-nights from November 2005 to October 2006) to assess bat activity among different sites in the Adelaide City parklands, temporal variations in activity (hourly, nightly, monthly), and responses to weather and light (artificial and moon).
